60kW 90kW DC Charger Station for Workplace and Depot Charging

Empowering the Modern Enterprise: A Technical Deep-Dive into MIDA Power’s 60kW and 90kW DC Charging Solutions for Workplace and Fleet Depot Environments

The global transition to electric mobility is no longer confined to the consumer market; it has become a central strategic pillar for the modern corporation. From the electrification of executive fleets to the decarbonization of last-mile delivery operations, the demand for reliable, efficient, and appropriately scaled charging infrastructure is skyrocketing. In this corporate landscape, the “sweet spot” of DC charging has emerged in the 60kW to 90kW range. These chargers provide the perfect balance between high-speed energy delivery and infrastructure cost-effectiveness, making them the ideal choice for workplaces, commercial depots, and hospitality settings.

MIDA Power (迈依达) introduces a specialized line of 60kW and 90kW DC Charging Stations, engineered to meet the rigorous demands of the corporate environment. Unlike high-power highway superchargers, workplace and depot chargers must prioritize long-term reliability, seamless fleet integration, and sophisticated load management to minimize utility demand charges. MIDA Power’s 60kW and 90kW solutions, featuring modular power electronics, advanced OCPP connectivity, and ruggedized IP54-rated cabinets, provide the technical foundation for a zero-emission business model.

1. Market & Policy Context: The Business Case for Workplace and Depot Charging

The adoption of 60kW and 90kW charging is driven by a combination of corporate sustainability mandates, employee expectations, and operational efficiency requirements.

The Shift to “Employee-Centric” Infrastructure

For many employees, the availability of workplace charging is the primary factor in their decision to switch to an electric vehicle. A 60kW or 90kW DC charger is the perfect “mid-day boost” tool. In the 4 to 8 hours a vehicle is parked during the workday, a 60kW charger can provide a full charge to even the largest battery packs, or a rapid top-up for employees with long commutes. This “amenity” has become a powerful recruitment and retention tool in the post-pandemic labor market.

The Decarbonization of Commercial Fleets

Logistics companies and service providers (plumbers, electricians, delivery services) are rapidly transitioning their fleets to electric. These vehicles typically operate on a predictable schedule, returning to a depot at night or during mid-day breaks. A 90kW MIDA charger allows for a “fast-turnaround” depot strategy, where a van can be significantly recharged in 30-45 minutes, ensuring maximum fleet utilization and minimizing the number of spare vehicles needed.

Regulatory Pressures and ESG Reporting

Government mandates (such as the UK’s workplace charging scheme or various U.S. state incentives) are providing financial support for corporate charging. Furthermore, public companies are now required to report on their Scope 1 and Scope 2 emissions. Installing MIDA 60kW/90kW infrastructure provides a quantifiable way to reduce the corporate carbon footprint while generating verifiable data for Environmental, Social, and Governance (ESG) reports.

2. Product Technical Deep-Dive: Reliability Meets Efficiency

MIDA Power’s 60kW and 90kW chargers are designed with a “Duty-Cycle First” approach, ensuring they can handle the constant usage patterns of a busy workplace or depot.

Modular Power Architecture and SiC Efficiency

At the core of the 60kW and 90kW units is MIDA’s proprietary power module technology.

• Redundancy and Reliability: By using 20kW or 30kW power modules in a parallel configuration, we ensure that the charger remains operational even if a single module encounters a fault. This “Graceful Degradation” is critical for depots where a broken charger can ground a delivery vehicle and disrupt operations.
• Silicon Carbide (SiC) Technology: Our latest generation of power modules utilizes SiC MOSFETs, achieving peak conversion efficiencies of over 95.5%. This reduces the heat generated within the cabinet, extending the lifespan of the electronics and lowering the corporate electricity bill through reduced conversion losses.

Wide Voltage Output (200V – 1000V)

Modern fleets are diverse. A workplace parking lot might host everything from a 400V Nissan Leaf to an 800V Porsche Taycan or a next-generation 900V electric delivery truck.

• Future-Proofing: MIDA chargers support the full output range up to 1000V DC. This ensures that the infrastructure installed today will be compatible with the high-voltage commercial vehicles of tomorrow.
• Low-Voltage Support: Our chargers are equally capable of providing efficient power to electric motorcycles, scooters, and light utility vehicles, which are increasingly common in urban logistics.

Thermal Management and Acoustic Optimization

Workplace environments require chargers that are quiet and unobtrusive.

• Intelligent Air Cooling: We utilize speed-controlled, low-noise fans that modulate based on the internal temperature. The airflow path is designed to prevent the intake of dust and debris, with critical electronics housed in an isolated compartment.
• Quiet Operation: Our chargers are designed to operate below 65dB, making them suitable for installation near office windows or in underground parking garages where noise can be amplified.

HMI and User Authentication

• 7-inch High-Brightness Touchscreen: Provides clear instructions for employees and fleet drivers. The interface supports multiple languages and can be customized with the corporation’s branding.
• Multi-Factor Authentication: We support RFID cards, mobile apps, and “Plug & Charge” (ISO 15118), ensuring that only authorized personnel can access the charging infrastructure.

3. Standards & Certifications: Safety in the Workplace

Corporate infrastructure must meet the highest safety standards to protect employees, property, and the power grid.

CE, UL, and TUV Certification

MIDA Power chargers are tested and certified to international standards.

• Electrical Safety: Our 60kW and 90kW units feature advanced insulation monitoring, residual current protection (RCD), and surge protection (SPD), ensuring safe operation in all weather conditions.
• EMC Compliance: Certified to residential and commercial EMC standards, our chargers will not interfere with office Wi-Fi networks, cellular signals, or sensitive lab equipment.

OCPP 1.6J and 2.0.1 Connectivity

Integration is the key to corporate charging.

• Fleet Management Integration: Our full support for OCPP allows MIDA chargers to connect to any corporate fleet management software. This enables “Smart Scheduling,” where vehicles are charged based on their next day’s route requirements.
• Energy Management: Support for OCPP 2.0.1 allows for sophisticated “Local Load Management,” where a cluster of chargers communicates to ensure they never exceed the building’s total electrical capacity.

ISO 15118 (Plug & Charge)

For fleet operations, speed of connection is vital. With ISO 15118, the driver simply plugs in the vehicle, and the charger automatically identifies the van, authorizes the session, and begins charging. No apps, no cards, no wasted time.

4. Application Scenarios: Where MIDA Power Delivers Results

The 60kW and 90kW range is the “utility player” of the EV infrastructure world.

Corporate Headquarters and Office Parks

For the white-collar workplace, these chargers provide a high-value perk. A 60kW charger allows a commuter to add 200km of range during a long lunch or a series of meetings. For the company, it demonstrates a commitment to innovation and sustainability.

Logistics Depots and Last-Mile Delivery

For delivery companies like DHL, DPD, or Amazon DSPs, the 90kW charger is the ideal depot solution. It is fast enough to support a “double-shift” model where vans are topped up during the mid-day driver changeover, but small enough to be installed in multiples without requiring a massive new grid transformer.

Hospitality and Destination Charging

Hotels, resorts, and conference centers are increasingly using 60kW DC charging to differentiate themselves. While Level 2 charging is sufficient for overnight guests, a 60kW DC charger is a powerful draw for business travelers and day-visitors who need a faster turnover.

5. Case Study: The “Eco-Logistics” Depot Rollout

A major regional delivery company sought to electrify its fleet of 50 delivery vans at three separate depots.

The Challenge: The depots had limited electrical capacity, and the vans needed to be fully charged in under an hour during the mid-day shift change. The hardware needed to be rugged enough for an industrial environment and fully integrated with the company’s existing dispatch software.

The Solution: MIDA Power supplied a fleet of 90kW DC Chargers with dual CCS2 ports. We worked with the customer to implement a “priority charging” algorithm, where the vans with the longest afternoon routes were given maximum power first. The ruggedized cabinets were installed on concrete plinths with heavy-duty bollards to protect against vehicle collisions.

The Result: The transition was completed in six months. The company saw a 20% reduction in total operating costs per mile compared to their previous diesel vans. The 90kW chargers maintained an uptime of 99.7%, ensuring that no delivery was ever missed due to a charging failure. The success of the pilot has led to a national rollout of MIDA Power hardware across all 20 of the company’s depots.

6. Expert Commentary: The MIDA Vision for Corporate Electrification

“The workplace is the new refueling station,” says Mr. Wang Da-Wei, Senior Engineer for Enterprise Solutions at MIDA Power. “But unlike a traditional gas station, a workplace charging site must be an intelligent part of the building’s ecosystem. Our 60kW and 90kW chargers are designed with this ‘Integrated Enterprise’ philosophy. We don’t just provide power; we provide data and control. By utilizing SiC technology, we’ve made these units smaller, quieter, and more efficient than anything else in their class. For a fleet manager or a facility director, MIDA represents a ‘Future-Proof’ investment that will support their sustainability goals for the next decade.”

7. Future Outlook & Scalability: Toward the “Smart Energy” Campus

The next decade will see the workplace charging station evolve into a central player in the “Smart Energy” movement.

Integration with Smart Buildings and Microgrids

Future MIDA 60kW/90kW chargers will be fully integrated with Building Management Systems (BMS). This allows a corporate campus to harmonize its energy use across lighting, HVAC, and EV charging. For example, if the building’s solar panels are producing excess energy, the chargers can automatically ramp up their output to “soak up” the clean power. Conversely, during periods of high grid prices, the chargers can modulate their load to save the company money.

The Move to V2B (Vehicle-to-Building)

As bi-directional technology matures, MIDA chargers will enable V2B applications. A company fleet of 50 electric vans represents a massive mobile battery. During a power outage or a period of peak grid demand, these vans can push energy back into the office building, keeping critical systems (like servers and security) operational. This adds a new layer of “Energy Resilience” to the modern enterprise.

AI-Driven Fleet Optimization

We are developing AI tools that can predict the optimal charging schedule for every vehicle in a corporate fleet. By analyzing route data, weather, and battery health, the system can ensure that every van is charged to the exact level needed for its next task—minimizing energy waste and extending the life of the vehicle’s battery.

8. Technical Deep-Dive: Load Balancing and Dynamic Power Management

In a workplace or depot, the primary challenge is not how fast one car can charge, but how many cars can charge simultaneously without overloading the electrical system. MIDA Power’s 60kW and 90kW units feature industry-leading load management capabilities.

Local vs. Cloud-Based Load Balancing

• Local Load Balancing (LLB): A group of chargers can be connected via a local network to a master controller. This controller monitors the total power draw in real-time. If multiple vehicles plug in simultaneously, the LLB system dynamically redistributes the available power, ensuring that the total limit (e.g., the building’s main breaker capacity) is never exceeded.
• Cloud-Based Management: For companies with multiple sites, our cloud platform allows for centralized energy management. A fleet manager can set global charging policies, such as “prioritize emergency vehicles” or “charge all vans between 10 PM and 6 AM to capitalize on off-peak rates.”

Priority-Based Charging

Our software allows for “User-Tiering.” Executive vehicles or critical delivery vans can be assigned “High Priority,” ensuring they always receive the maximum available power. Other vehicles, such as those belonging to employees who will be in the office all day, can be assigned “Low Priority” and charged more slowly over a longer period.

9. Economic Analysis: The TCO and ROI of Enterprise Charging

Investing in MIDA 60kW/90kW infrastructure is a sound financial decision with a clear path to ROI.

Operational Savings for Fleets

The primary driver for depot charging is the displacement of fuel costs. Electric vans are significantly cheaper to “fuel” than diesel ones, especially when charging is managed to capitalize on off-peak utility rates. Furthermore, EVs require less maintenance (no oil changes, fewer moving parts), leading to a lower Total Cost of Ownership (TCO) over the vehicle’s lifespan.

Employee Productivity and Attraction

Providing 60kW charging at the workplace saves employees time. They no longer need to make dedicated trips to public fast chargers or gas stations. This “reclaimed time” translates into higher productivity and job satisfaction. For the company, the ability to attract top-tier talent in a competitive market is an invaluable “Soft ROI.”

Tax Incentives and Government Grants

Many regions offer significant tax credits or direct grants for workplace charging infrastructure. In the UK, the Workplace Charging Scheme (WCS) provides support for up to 75% of the purchase and installation costs. In the US, various federal and state programs offer similar incentives. MIDA Power hardware, with its CE/UL certifications and high efficiency, is a top-tier candidate for these programs.

16. Employee Wellness and the Role of Workplace Charging

Beyond the technical and economic benefits, providing 60kW/90kW charging at the workplace has a profound impact on employee wellness and work-life balance.

Reducing “Range Anxiety” and Daily Stress

For many employees, the transition to an EV is accompanied by a new form of stress: the fear of running out of power before reaching home. By providing a reliable “mid-day boost” at 60kW, employers directly alleviate this anxiety. An employee can arrive at work with a low battery, plug in, and by the time they finish their first meeting, they have more than enough range for their return journey and subsequent errands. This mental peace of mind translates into higher focus and lower stress during the workday.

Promoting Sustainable Lifestyles

A company that provides high-quality EV infrastructure is actively supporting its employees’ personal sustainability goals. It makes the “Green Choice” the easy choice. This alignment of corporate values and personal ethics fosters a stronger sense of community and shared purpose within the workforce.

17. Advanced Power Module Cooling Techniques for Silent Depots

In the 60kW and 90kW range, thermal management is key to both longevity and workplace comfort. MIDA Power has pioneered several advanced cooling techniques that set our hardware apart.

Integrated Heat Pipe Technology

Within our 30kW power modules, we utilize high-performance copper heat pipes to transport thermal energy away from the SiC MOSFETs to the primary radiator surfaces. This technology, which requires no moving parts, allows for much more efficient heat transfer than simple aluminum extrusions. By reducing the “bottleneck” at the chip level, we can run our external fans at much lower speeds, making the MIDA 90kW unit one of the quietest in the industry.

Isolated Airflow Design (IP54 Optimized)

Traditional chargers often draw cooling air directly over the sensitive electronics, which can lead to the buildup of conductive dust or corrosive moisture. MIDA Power utilizes a “Dual-Chamber” design. The cooling air is moved through a dedicated thermal channel that is physically isolated from the control boards and power components. Heat is transferred via the heat-pipe radiators into the airflow, but the electronics themselves remain in a clean, sealed environment. This is why our chargers maintain their efficiency for years, even in dusty depot environments.

18. The Strategic Advantage of 60kW and 90kW for Scalability

One of the biggest mistakes enterprise fleet managers make is over-specifying their charging needs.

Why 60kW/90kW is the “Smart Choice” over 350kW

While 350kW chargers are impressive, they are often overkill for a depot or workplace.

• Grid Footprint: A single 350kW charger can consume the entire spare capacity of a medium-sized office building. In contrast, for the same grid “budget,” a company can install three or four 90kW MIDA units, allowing them to serve much more of their fleet simultaneously.
• Cost Efficiency: The cost per port for 90kW charging is significantly lower than for 350kW systems. For a fleet manager, the goal is “total energy delivered per day,” and a distributed network of 90kW chargers often delivers more total kWh than a single ultra-fast charger that is only utilized intermittently.

19. A Partnership for the Long Haul

At MIDA Power (迈依达), we don’t just sell you a charger; we join you on your electrification journey. We understand that for a corporation, infrastructure is a 10 to 15-year commitment.

21. Installation and Commissioning: A Professional Roadmap for the Corporate Site

The installation of 60kW and 90kW chargers in a workplace or depot environment requires a strategic approach that balances technical requirements with minimal disruption to daily business operations. MIDA Power provides a detailed roadmap to ensure that your facility is ready for the electric transition.

Site Survey and Electrical Load Assessment

The first step is a comprehensive audit of the building’s electrical system. For 60kW/90kW units, a 400V three-phase supply is required. MIDA’s engineering team works with your facility managers to identify the best connection points, often utilizing existing sub-panels to reduce cabling costs. We perform a “Peak Load Analysis” to determine how the new charging demand will interact with the building’s HVAC, lighting, and industrial machinery. This allows us to configure the “Local Load Management” parameters during commissioning to prevent any risk of tripping the main building breaker.

Civil Engineering and Dispenser Placement

In a workplace parking lot, aesthetics and accessibility are key. For depots, durability and vehicle flow are the priorities. MIDA offers both floor-mounted and wall-mounted variants for the 60kW/90kW series. We recommend placing dispensers in a “Dual-Head” configuration between two parking stalls to maximize the utility of the hardware. Our installation guides specify high-durability bollards and protective curbs to safeguard the units from low-speed vehicle impacts common in busy depots.

Commissioning and Software Handshake

Once the hardware is physically installed and wired, the digital commissioning process begins. This involves connecting the chargers to the MIDA Cloud or a 3rd-party fleet management platform via 4G or Ethernet. We perform a full “System Integrity Test,” including insulation resistance checks and ground fault simulation. The final step is a live charging test with a fleet vehicle to verify that the OCPP communication, user authentication (RFID/App), and dynamic power sharing are all functioning according to the enterprise’s specific policies.

22. Maintenance and TCO Optimization for Commercial Depot Operations

For a fleet manager, the Total Cost of Ownership (TCO) is a critical metric. MIDA Power has engineered the 60kW and 90kW series to be the most cost-effective solution in their class over a 10-15 year lifespan.

Efficiency and the Bottom Line

The 95.5%+ efficiency of MIDA’s SiC-based power modules is not just a technical boast; it is a financial advantage. In a high-usage depot where chargers might run for 12 hours a day, the difference between a 90% and a 95.5% efficient charger can save over $3,500 in electricity costs per year, per unit. Over the life of the charger, this efficiency gain alone can pay for a significant portion of the initial hardware cost.

Preventive Maintenance and Uptime Guarantees

Workplace and depot chargers often face high utilization. MIDA Power utilizes a “Predictive Maintenance” model powered by internal sensors. These sensors monitor the health of the cooling fans, the internal temperature of the power modules, and the signal quality of the communication boards. If a fan begins to slow down or a module shows signs of thermal drift, our system automatically alerts the facility manager and MIDA support. This allows for “Non-Disruptive Maintenance,” where parts are replaced before they fail, ensuring that your fleet is never grounded.

Modular Upgradability

As charging technology advances, MIDA’s modular architecture allows your infrastructure to evolve. Our 60kW units can often be field-upgraded to 90kW by adding additional power modules and updating the firmware, provided the site’s electrical capacity allows it. This prevents the need for a full rip-and-replace of the charging hardware as your fleet grows.

23. Technical Deep-Dive: SiC Power Modules and Thermal Management for High-Usage Depots

The reliability of MIDA’s 60kW and 90kW chargers in demanding industrial environments is the result of surgical-level engineering in power conversion and thermal control.

The Role of Silicon Carbide (SiC) in Commercial Charging

In the 60kW to 90kW range, heat is the primary enemy of electronics. Traditional silicon-based chargers generate significant waste heat, requiring large, noisy fans. MIDA’s Gen-3 SiC MOSFETs allow for much higher switching frequencies with significantly lower thermal losses. This allows us to pack 90kW of power into a cabinet that is 40% smaller than our competitors’, while maintaining a much quieter operating profile (below 65dB).

Advanced Airflow and Environmental Sealing (IP54)

Depots are often dusty and can be exposed to moisture and industrial pollutants. MIDA Power chargers utilize a “Dual-Path” cooling system. The sensitive control electronics and the main power modules are housed in a sealed, IP54-rated inner chamber. Heat is transferred to the external airflow via high-efficiency aluminum heat sinks. This ensures that the cooling air—which may contain dust or moisture—never comes into contact with the critical digital components. This “Isolation Cooling” is the reason why MIDA chargers have a significantly lower failure rate in harsh depot environments compared to standard air-cooled units.

24. Comprehensive FAQ for Workplace and Fleet Managers

Q1: Is a 60kW charger fast enough for a typical office workday? Yes, it’s more than enough. A 60kW charger can add approximately 150-200 miles of range in just one hour. For an employee parked for 8 hours, even a much lower power level would suffice, but the 60kW output allows for “Opportunity Charging” for guests or employees who only have a short time between meetings.

Q2: How does the MIDA charger handle the billing for employees vs. company fleet vehicles? Our software allows for “Account Tiers.” You can set up your system so that company fleet vehicles charge for free (tracked for internal accounting), while employees pay a subsidized rate via an RFID card or a mobile app.

Q3: Can the 90kW charger be used for electric delivery trucks? Absolutely. 90kW is the ideal power level for Class 3-6 delivery vans and trucks. It allows for a significant recharge during a driver’s lunch break or a quick turnaround between shifts.

Q4: Does the charger support “Plug & Charge”? Yes, via the ISO 15118 standard. This is particularly useful for depots, as it allows drivers to simply plug in and walk away, with the vehicle being automatically identified and authorized.

Q5: What is the benefit of the 1000V voltage range? While most current passenger EVs are 400V, many new commercial vehicles and high-performance cars are moving to 800V or higher. The 1000V range ensures your workplace chargers won’t be obsolete in three years.

Q6: Can I install multiple 90kW chargers if I have limited grid capacity? Yes. MIDA’s “Dynamic Load Management” allows you to install, for example, four 90kW units on a 200kW electricalservice. The system continuously meters the site’s total draw and dynamically allocates power among the four units, prioritizing vehicles on tight schedules while gently throttling back when building load spikes. The result: you can install more charging capacity than your nominal service would suggest, defer a costly transformer upgrade, and still guarantee every vehicle a full battery by the morning shift. When the building is empty overnight, all four units run at full 90kW with no conflict at all.

Q7: How does the 90kW charger perform in hot climates or poorly ventilated garages? Our smart airflow design draws cool air from below and exhausts heat through the top, while the IP54-sealed enclosure keeps dust and moisture away from the electronics. The units are rated for full output up to 50°C ambient, and the variable-speed fans run only as fast as needed—so a basement parking garage stays quiet during overnight charging, and the modules stay well inside their thermal envelope even on 40°C summer days.

Q8: Can employees use the charger when it is configured for the fleet? Yes—this is one of the most popular workplace features. The “Account Tiers” system lets you reserve a portion of capacity for fleet vehicles with priority access, then open the remaining capacity to employees at a subsidized rate via RFID or the mobile app. The same dashboard that tracks fleet energy for internal accounting also generates employee billing records automatically.

Q9: What happens during a power outage? The charger powers down safely and restarts automatically when the grid returns, resuming any authorized sessions without manual intervention. For sites that need resilience, MIDA offers a battery-backed variant that keeps a dispenser alive during outages—ideal for depots where the first shift cannot afford to wait for the grid.

Q10: What does the installation and commissioning process look like? MIDA’s project team handles site assessment, grid coordination, delivery, and commissioning, and most 90kW units are operational within 48 hours of arriving on site. We also provide staff training and a digital handover package, including full electrical drawings and a maintenance schedule for your facilities team.

Making the Business Case at the Depot

For workplace and fleet managers, the 90kW platform’s value is best understood through a simple scenario: a depot with eight electric delivery vans, each returning with roughly 30% state of charge and needing a full battery for the next day. With four MIDA 90kW chargers on dynamic load management, the fleet completes its entire recharge between the last return and the first departure—about 8 hours—without exceeding the 200kW service, while the building’s HVAC, lighting, and office loads run uninterrupted. The avoided transformer upgrade alone typically covers a quarter of the hardware cost, and the off-peak charging schedule the software enforces cuts the energy bill by 15-25% versus uncontrolled daytime charging. That is the difference between electrification as an expense and electrification as an investment with a visible payback line.

Key Takeaways

• Dynamic load management lets depots install four 90kW units on a 200kW service and grow into full capacity later.
• 90kW is the sweet spot for Class 3-6 delivery vans and trucks—a full recharge in a lunch break or between shifts.
• Account tiers and RFID/app billing let fleet and employee charging coexist on the same hardware with separate ledgers.
• ISO 15118 Plug & Charge and 1000V output future-proof the depot for 800V vehicles and walk-away driver workflows.
