90KW 180KW 150kW 240kW CHAdeMO Fast Charger with CCS2 Combo Dispenser

90KW 180KW 150kW CHAdeMO Fast Charger with 240kW CCS2 Combo Dispenser: Engineering the Future of Multi-Standard Public EV Infrastructure

The global transition toward electric mobility is no longer a peripheral trend but a central pillar of international industrial and environmental policy. As nations race to decarbonize their transportation sectors, the demand for robust, high-performance, and versatile charging infrastructure has reached an all-time high. MIDA Power (迈依达), at the forefront of this revolution, presents a sophisticated solution designed to bridge the gap between legacy standards and the next generation of ultra-fast charging: the 90KW 180KW 150kW 240kW CHAdeMO Fast Charger paired with a 90KW 180KW 150kW 240kW CCS2 Combo Dispenser. This dual-standard system is engineered not just for today’s fleet but for the diverse, high-voltage ecosystems of the next decade.

1. Market and Policy Context: Navigating the Multi-Standard Landscape

The current EV landscape is characterized by a divergence in charging standards that reflects the regional and historical development of the industry. In Europe and many parts of Asia-Pacific and Oceania, the Combined Charging System 2 (CCS2) has emerged as the dominant protocol, supported by major manufacturers like Volkswagen, BMW, and Hyundai. Simultaneously, the CHAdeMO standard—pioneered by Japanese automakers—remains a critical requirement for millions of vehicles on the road, including the Nissan Leaf and various Mitsubishi models.

Government policies, such as the European Union’s Alternative Fuels Infrastructure Regulation (AFIR) and the U.S. National Electric Vehicle Infrastructure (NEVI) formula program, emphasize the need for “interoperable and accessible” charging points. For a charging station operator (CPO), the challenge lies in maximizing asset utilization while ensuring no driver is left stranded. MIDA Power’s 90KW 180KW 150kW 240kW split-system addresses this by providing high-speed service to both CCS2 and CHAdeMO users simultaneously, ensuring that a single installation can serve the broadest possible demographic of EV owners.

Furthermore, as grid capacity becomes a premium commodity, the implementation of such high-power systems requires a deep understanding of energy management. The integration of 150kW and 240kW outputs allows for dynamic allocation, ensuring that power is delivered where it is needed most without exceeding the site’s total power budget.

2. Product Technical Deep-Dive: The Core of MIDA Engineering

At the heart of the MIDA 150kW/240kW system lies a modular power conversion architecture that sets the industry benchmark for reliability and efficiency. Unlike monolithic systems that suffer from total failure if a single component fails, MIDA uses a rack-mounted module design.

Power Modules and Efficiency

The system utilizes 30kW or 40kW high-efficiency power modules. These modules achieve a peak conversion efficiency of over 95.5%, significantly reducing energy loss as heat. This efficiency is critical for long-term operational profitability, as it minimizes the “vampire” costs associated with DC-to-AC conversion. The modules feature wide-bandgap semiconductors, such as Silicon Carbide (SiC), which allow for higher switching frequencies and better thermal performance than traditional silicon-based IGBTs.

Wide Voltage Range: 200V to 1000V

Modern EVs are evolving from 400V architectures to 800V systems (such as the Porsche Taycan, Lucid Air, and Hyundai IONIQ 6). To remain future-proof, the MIDA charger offers a wide output voltage range of 200V to 1000V DC. This ensures that the charger can deliver maximum current to older 400V packs while providing the high-voltage throughput required to charge 800V vehicles at their peak rates. On the 240kW CCS2 dispenser, this translates to a massive surge of power that can add hundreds of miles of range in under 15 minutes.

Connectors and Standards Integration

The dual-head configuration is the defining feature of this model. The 150kW CHAdeMO connector is liquid-cooled or high-amp air-cooled (depending on configuration) to maintain a steady 200A or higher flow without overheating. The 240kW CCS2 dispenser is the “heavy hitter,” designed to handle up to 500A (liquid-cooled cables) to reach the 240kW peak. The system intelligently balances these loads. If a Nissan Leaf is charging at 50kW on the CHAdeMO side, the remaining power is dynamically shifted to the CCS2 side to provide maximum speed to a parked luxury sedan or electric truck.

Thermal Management and Liquid Cooling

High-power charging generates significant heat. MIDA Power employs an advanced thermal management system. For the internal power modules, an independent air duct design prevents dust and salt spray from coming into direct contact with the sensitive electronics, achieving an IP54 or IP55 rating. For the 240kW dispenser cables, MIDA utilizes specialized liquid-cooling technology. A coolant circulate through the charging cable and the connector pins, keeping the temperature well below the 50°C safety threshold even during continuous high-current operation. This allows for a thinner, lighter cable that is easier for the end-user to handle compared to bulky, air-cooled 500A cables.

Cabinet and Split Design

The 150kW/240kW system is typically deployed in a split-cabinet configuration. The main power unit (the “brain” and “heart”) is housed in a robust, weather-resistant cabinet that can be placed in a utility area or at the back of a parking lot. The dispensers (the “limbs”) are sleek, user-facing pedestals. This design saves valuable space at the parking bay and reduces the noise heard by the user, as the large cooling fans of the main power cabinet are located away from the charging point.

3. Standards & Certifications: The MIDA Guarantee of Safety

Compliance is non-negotiable in the high-voltage EV sector. MIDA Power’s systems are rigorously tested to meet and exceed global standards:

• CE & TUV: Ensuring compliance with European safety, health, and environmental protection requirements.
• UL & ETL: For the North American market, our systems meet the UL 2202 and UL 2231 standards for DC fast charging safety.
• OCPP 1.6J and 2.0.1: MIDA chargers are fully compatible with the Open Charge Point Protocol. This allows CPOs to integrate our hardware with any management software for billing, remote diagnostics, and load balancing.
• ISO 15118 (Plug & Charge): The 240kW CCS2 side supports the ISO 15118 protocol, enabling “Plug & Charge” functionality. The car and the charger communicate directly, identifying the user and processing payment automatically without the need for an RFID card or mobile app.

3. Advanced Component Engineering & Material Science: The MIDA Standard of Quality

Beyond the primary power conversion, the longevity and reliability of a 150kW/240kW system depend on the quality of its smallest components and the materials used in its construction. At MIDA Power, we select every part with a “ten-year service life” philosophy.

Precision Semiconductor Selection

The use of Silicon Carbide (SiC) MOSFETs in our 40kW modules is a deliberate choice to handle the high-frequency switching required for 1000V output. SiC components offer three times the thermal conductivity of standard silicon, allowing them to dissipate heat more effectively. This reduces the size of the internal heat sinks and allows for a more compact power module. Each MOSFET is rigorously tested for voltage spikes and thermal stress before being integrated into the module.

High-Grade Magnetic Components

The transformers and inductors within the MIDA power stack are custom-wound to minimize eddy current losses and skin effect at high frequencies. We use high-permeability nanocrystalline cores that maintain their magnetic properties even at high operating temperatures. This attention to magnetic design ensures that the charger operates with a high power factor (>0.99) and extremely low Total Harmonic Distortion (THD < 5%), protecting the local electrical grid from noise and interference.

Robust Cabinet Construction

The exterior of the power cabinet and the dispensers is constructed from 2.0mm thick galvanized steel, treated with a specialized multi-layer anti-corrosion coating. This coating is designed to withstand 1,000 hours of salt spray testing, making the system ideal for coastal installations. The gaskets and seals are made from high-grade silicone, which maintains its elasticity in temperatures ranging from -40°C to +85°C, ensuring the IP55 rating remains intact for years.

Ergonomic Dispenser and Cable Design

The user-facing dispenser is designed with ergonomics in mind. The height of the screen and the placement of the cable holsters are optimized for accessibility, meeting ADA (Americans with Disabilities Act) requirements and similar international standards. The 500A liquid-cooled cables are sourced from industry leaders and feature a reinforced outer jacket that is resistant to oil, UV radiation, and mechanical abrasion.

4. Software Ecosystem & Cybersecurity: Protecting the Digital Core

In the age of connected infrastructure, a charging station is as much a digital asset as a physical one. MIDA Power’s software stack is built for security, interoperability, and ease of management.

RTOS-Based Control Logic

The internal control systems of the charger run on a high-performance Real-Time Operating System (RTOS). This ensures that critical safety tasks—such as ground fault detection and over-current protection—are executed with microsecond precision. The RTOS architecture also allows for multi-threaded operation, enabling the charger to communicate with the vehicle, the cloud backend, and the local energy management system simultaneously without any lag.

Advanced Cybersecurity Measures

Charging stations are part of a nation’s critical infrastructure, and MIDA takes their protection seriously. Our chargers implement:

• Hardware Security Modules (HSM): For the secure storage of cryptographic keys used in TLS 1.2/1.3 communication.
• Secure Boot: Ensuring that only authorized, digitally signed firmware can run on the device.
• Encrypted Local Storage: Protecting user data and transaction logs stored on the device from physical tampering.
• Regular Security Audits: We conduct frequent penetration testing and vulnerability assessments to stay ahead of emerging threats.

Over-The-Air (OTA) Updates

The EV landscape is constantly evolving, with new vehicle models and software protocols being released every month. MIDA chargers feature a robust OTA update mechanism. This allows CPOs to push firmware updates to an entire fleet of chargers with a single click from their management dashboard. Whether it’s an update to the ISO 15118 stack or a new feature for the user interface, your MIDA charger will always be at the cutting edge of technology.

5. Environmental & Electrical Resilience: Surviving the Extremes

MIDA Power chargers are deployed in some of the most challenging environments on Earth—from the scorching deserts of the Middle East to the freezing tundras of Scandinavia.

Thermal Management Strategies

Our dual-circuit cooling system is a masterpiece of thermal engineering. For the power modules, we use a forced-air system with an independent air duct. This means the air that cools the electronics never touches the electronics directly, preventing the build-up of dust and moisture that causes short circuits. For the liquid-cooled cables, the cooling unit is integrated into the dispenser, utilizing a non-conductive, biodegradable coolant that is safe for the environment.

Lightning and Surge Protection

Electrical storms can be devastating for high-voltage equipment. Every MIDA charger is equipped with Type 2 Surge Protection Devices (SPD) on both the AC input and the DC output. We also include integrated lightning protection and grounding monitoring systems that will automatically shut down the charger if a fault is detected, protecting the vehicle and the internal electronics from permanent damage.

Grid Stability and Power Quality

High-power chargers can place significant stress on the local grid. MIDA chargers include advanced filtering and active power factor correction to ensure they present a “clean” load. We also support sophisticated load shedding and peak shaving protocols, allowing the charger to reduce its power draw in response to signals from the grid operator, helping to prevent blackouts and reduce electricity costs.

4. Application Scenarios: Where the 150kW/240kW Split System Shines

The versatility of the MIDA 150kW CHAdeMO / 240kW CCS2 system makes it a preferred choice across several high-stakes commercial environments. Because it addresses two distinct segments of the market—legacy high-performance vehicles and new-age ultra-fast platforms—it offers a level of future-proofing that few other chargers can match.

A. Strategic Highway Corridors and Rest Stops

On major highways, time is the most valuable commodity for the driver. A traveler stopping for a coffee or a quick meal needs to know they can gain 200+ kilometers of range in the time it takes to visit the restroom. The 240kW CCS2 dispenser is designed for exactly this. Vehicles with 800V architectures can pull the full 240kW, while the 150kW CHAdeMO head ensures that older, yet still highly prevalent, long-range EVs are not left out of the high-speed network. By placing these units every 50-80 kilometers, CPOs can create a seamless cross-continental charging experience.

B. Intermodal Logistics and Port Facilities

The transition of heavy-duty and medium-duty transport to electric is well underway. Ports and logistics hubs require chargers that can handle continuous, high-current operation for delivery vans and semi-trucks. The split design of the MIDA system allows the power cabinet to be tucked away in a safe, low-traffic area, while the dispensers are positioned at the loading docks. The 240kW output is sufficient to fast-charge a medium-duty delivery truck during a driver’s break, ensuring that the fleet remains productive and the delivery schedule is met.

C. Public Charging Hubs in Transitioning Markets

In markets where the transition from CHAdeMO to CCS2 is still in progress (such as parts of Eastern Europe, Southeast Asia, and the UK), this dual-standard unit serves as a critical bridge. It prevents the alienation of the early-adopter community who own CHAdeMO vehicles while providing the ultra-fast speeds required to attract new buyers of high-end German and Korean EVs. For the investor, this maximizes the “Fill Rate” of the station, as the unit is almost never idle due to a lack of compatible vehicles.

5. Case Study: The “Green Highway” Transformation at the Brenner Pass

To illustrate the real-world impact of the MIDA 150kW/240kW system, we look at a recent installation along one of Europe’s busiest mountain transit routes: the Brenner Pass. The project was initiated by a regional consortium aiming to reduce the carbon footprint of trans-Alpine logistics.

The Challenge

The site was a high-altitude rest stop subject to extreme temperature fluctuations—from -20°C in winter to 35°C in summer. The grid connection was stable but limited, meaning that every kilowatt of power had to be managed with surgical precision. The site also had to serve a diverse mix of vehicles: local commuter EVs, long-haul electric vans, and a steady stream of tourists from both Northern and Southern Europe.

The MIDA Solution

Four MIDA split-system units were installed. Each power cabinet was placed in a climate-controlled enclosure, while the dispensers were ruggedized for the mountain environment. MIDA’s Dynamic Load Balancing was configured to prioritize the 240kW CCS2 heads during peak daylight hours when tourist traffic was highest, while providing steady 150kW service to the fleet of CHAdeMO-equipped delivery vans used by local Alpine businesses.

The Outcome

Within the first six months of operation, the station recorded an uptime of 99.8%. The liquid-cooled cables on the 240kW dispensers proved to be a user favorite, as they remained flexible and easy to handle even in sub-zero temperatures. The regional consortium reported that the ability to serve CHAdeMO vehicles brought in an additional 25% of revenue that would have been lost if they had installed CCS2-only stations. Most importantly, the high-voltage capability of the 240kW side ensured that the newest 800V EVs could charge at their maximum rate, reducing station congestion and improving throughput.

6. Expert Commentary: Insights from MIDA’s Engineering Excellence

Dr. Zhang Wei, Technical Director at MIDA Power, has overseen the development of our high-power charging platforms for over a decade. In his words:

“The engineering challenge of a 150kW/240kW split system isn’t just about the raw wattage. It’s about the management of that power. When you have a 500-amp current flowing through a cable, you are dealing with immense magnetic forces and thermal loads. Our decision to use Silicon Carbide (SiC) modules was a game-changer. It allowed us to shrink the footprint of the power stack while pushing the efficiency boundary above 95.5%.

Furthermore, the split-cabinet architecture is a direct response to what our customers told us. They don’t want a 2-meter tall monolith blocking their parking bays. They want a sleek, ergonomic dispenser that feels like a traditional fuel pump but delivers the energy of a small substation. By isolating the power modules in a separate cabinet, we protect the ‘brains’ of the system from the dust and grime of the parking lot, significantly extending the service life of the electronics.”

7. Future Outlook and Scalability: The Path to 480kW and Beyond

The 150kW/240kW system is designed to be the foundation of a scalable network. As battery technology improves and charging speeds increase even further, MIDA Power is already preparing the next iteration of this technology.

Modular Upgradability

Because our systems are built on a modular rack design, a 150kW cabinet can be upgraded to 180kW or 200kW simply by adding more power modules, provided the site’s grid connection allows for it. This “pay-as-you-grow” model is incredibly attractive to CPOs who want to manage their initial capital expenditure (CAPEX) while keeping the door open for future growth.

V2G and Grid Stabilization

We are currently integrating Bi-Directional charging capabilities into our high-power platforms. In the near future, these 150kW and 240kW units will not just take power from the grid—they will be able to push it back. During peak demand events, the thousands of EVs connected to MIDA chargers across a region can act as a massive virtual power plant, providing the stability needed to integrate more renewable energy sources like wind and solar.

The Era of Megawatt Charging

While 240kW is current state-of-the-art for passenger vehicles, MIDA is already testing Megawatt Charging System (MCS) prototypes for the heavy trucking industry. The lessons learned in thermal management and liquid-cooling from the 240kW CCS2 dispenser are being applied to create 1MW+ systems that can charge a Class 8 electric truck in under 30 minutes.

6. Manufacturing Excellence & Quality Assurance: The MIDA Promise

The reliability of a 150kW/240kW charger is not just a result of its design, but of the precision with which it is manufactured. MIDA Power operates a state-of-the-art production facility where every unit undergoes a rigorous testing process that exceeds international standards.

Automated Assembly and Precision Engineering

Our manufacturing floor utilizes a combination of advanced robotics and highly skilled technicians. The PCB assembly for our 40kW power modules is performed by high-speed SMT (Surface Mount Technology) lines, ensuring perfect component placement and soldering quality. Every board is then inspected by an Automated Optical Inspection (AOI) system to detect even the smallest defects. This level of automation is critical for maintaining the high power density and efficiency that MIDA is known for.

The “Burn-In” Stress Test

Before a charger leaves our factory, it must prove itself. Every 150kW/240kW system is subjected to a 48-hour “burn-in” test. During this process, the charger is run at its maximum rated power in a climate-controlled chamber that simulates the most extreme operating conditions. We monitor every internal sensor, checking for voltage ripples, thermal spikes, or communication errors. If a unit shows even the slightest inconsistency, it is returned to the engineering team for analysis. This ensures that every MIDA charger arrives at the site ready for years of trouble-free operation.

Material Integrity and Supply Chain Ethics

MIDA Power is committed to using only the highest quality raw materials. We source our steel, copper, and specialized plastics from certified suppliers who share our commitment to environmental responsibility. Our supply chain is transparent, and we conduct regular audits to ensure that the minerals used in our semiconductors and the materials in our cables are sourced ethically. We believe that a green product must have a green soul, from the factory floor to the final installation.

Specialized Anti-Corrosion Treatment

For our high-power cabinets, we utilize a proprietary multi-layer coating process. The steel is first galvanized to provide a base layer of protection, followed by an electrophoretic primer and a final coat of high-durability polyester powder. This system is designed to provide maximum resistance to the UV radiation and salt spray found in coastal environments. Our testing includes a 1,000-hour salt spray challenge, which ensures that the MIDA 150kW/240kW system will not rust or degrade even in the harshest seaside locations.

7. Maintenance & Operational Best Practices: Maximizing Your ROI

A high-power DC charger is a significant investment, and proper maintenance is the key to ensuring a long and profitable service life. MIDA Power provides a comprehensive support ecosystem to help CPOs maximize their uptime.

Predictive Maintenance and Remote Diagnostics

Thanks to our advanced software stack, most maintenance tasks can be managed remotely. The MIDA Cloud platform provides CPOs with real-time visibility into the health of their entire network. The system uses AI-driven algorithms to identify patterns that might indicate a future failure—such as a cooling fan that is beginning to draw more current than normal or a power module that is running slightly hotter than its peers. This allows the CPO to schedule a service visit before a breakdown occurs, ensuring maximum availability for the drivers.

Simple Field Serviceability

We have designed the MIDA 150kW/240kW system to be as easy to service as possible. The modular design means that most repairs can be completed in under 30 minutes. If a power module fails, a technician can simply swap it out for a new one without the need for specialized tools or complex wiring. The dispensers are also designed for easy access, with all critical components located behind a secure, front-opening panel. This minimizes the cost of field service and reduces the time the station is out of service.

Cleaning and Environmental Care

To maintain the efficiency of the cooling system, we recommend regular cleaning of the air intakes and filters. In dusty or high-pollution environments, this might be necessary every three to six months. We also provide specialized cleaning kits for the charging connectors to ensure that the silver-plated contacts remain free of debris and oxidation, maintaining the highest possible conductivity and preventing overheating during high-current sessions.

8. The Roadmap to Net-Zero: MIDA’s Sustainability Vision

At MIDA Power, we don’t just build chargers; we are building the infrastructure for a zero-emission world. Our 150kW/240kW systems are a key part of our vision for a sustainable future.

Circular Economy and Recyclability

We design our products with their end-of-life in mind. Over 90% of the materials used in a MIDA charger—including the steel cabinet, the copper wiring, and the aluminum heat sinks—are fully recyclable. We are also working on a “take-back” program where we refurbish older chargers and give them a second life in less demanding applications, ensuring that our products have the longest possible impact on the planet with the smallest possible footprint.

Powering the Grid of the Future

As renewable energy sources like wind and solar become more prevalent, the grid needs a way to store and manage that energy. The MIDA 150kW/240kW system is designed to be a part of the solution. By integrating with on-site solar and battery storage systems, our chargers can help to stabilize the local grid and ensure that EVs are always charged with the cleanest possible power. We are also leading the way in V2G (Vehicle-to-Grid) research, which will turn every EV into a mobile energy storage unit that can support the grid during times of need.

Global Collaboration for a Greener Planet

The climate crisis is a global challenge that requires a global response. MIDA Power actively participates in international standards organizations and collaborates with governments and NGOs around the world to promote the adoption of electric mobility. We believe that by sharing our engineering expertise and our commitment to quality, we can help to accelerate the transition to a sustainable future for everyone.

9. The Global EV Landscape in 2030 and MIDA’s Role: A Visionary Outlook

As we look toward the year 2030, the transportation sector will be unrecognizable compared to today. The convergence of electric mobility, autonomous driving, and renewable energy will have created a new paradigm for how people and goods move across the planet. MIDA Power is not just watching this future unfold; we are building the infrastructure that will define it.

The Rise of the Autonomous Mega-Hub

By 2030, the traditional gas station will be a relic of the past, replaced by multi-standard “Mega-Hubs” capable of charging hundreds of vehicles simultaneously. MIDA’s 150kW/240kW systems are the precursors to these massive energy centers. We envision hubs where hundreds of megawatts of power are managed by AI-driven systems, seamlessly distributing energy to passenger cars, heavy trucks, and even autonomous delivery drones. The reliability and flexibility of our current split-system architecture will be the foundation of these future giants. In this landscape, the 240kW output will be considered a “standard” speed, while ultra-performance stations will reach megawatt levels for heavy logistics.

The Shift Toward Solid-State and Beyond

Battery technology is on the cusp of a revolution. By 2030, solid-state batteries will likely be in mass production, offering higher energy density and significantly faster charging rates. MIDA’s wide-voltage architecture (up to 1000V) is already prepared for these advancements. Our 150kW/240kW platforms will be able to interface with these new chemistries, providing the precise voltage and current control necessary to maximize their lifespan and performance. We are also exploring the integration of silicon-anode and sodium-ion technologies into our broader charging ecosystem, ensuring that MIDA remains the most versatile partner for the global battery industry.

Decentralized Energy Markets and Peer-to-Peer Charging

The 2030 energy grid will be highly decentralized. Homeowners, businesses, and fleet operators will not just consume power; they will trade it. MIDA Power is developing the blockchain-based software layers that will enable these peer-to-peer energy transactions. A MIDA charger will be a digital gateway that allows a vehicle owner to sell their stored energy to a neighbor or back to the grid during peak demand events. This transformation of the EV from a “load” into a “resource” is the key to a resilient and sustainable power network.

Urbanization and the Integration of Vertical Mobility

As urban centers become more crowded, mobility will move into the third dimension. Electric Vertical Take-Off and Landing (eVTOL) aircraft—also known as “flying taxis”—will require high-power DC charging infrastructure at vertiports. The lessons MIDA has learned in engineering 240kW liquid-cooled systems for ground vehicles are directly applicable to the aerospace industry. We envision a future where MIDA power cabinets provide the energy for a city’s entire electric fleet, from the cars on the street to the taxis in the sky.

MIDA Power as a Global Energy Catalyst

Our role in 2030 will extend far beyond manufacturing hardware. MIDA Power will be a global catalyst for the energy transition, providing the data, the software, and the engineering expertise to help nations achieve their net-zero goals. We believe that by democratizing high-power charging and making it more efficient and accessible, we can help to create a world where clean, sustainable mobility is a right, not a privilege. The 150kW/240kW system is just the beginning of our contribution to this global effort.
