400kW Liquid-Cooled DC Fast Charger | Ultra-Fast EV Station

Product Overview

The 400kW Liquid-Cooled DC Fast Charger | Ultra-Fast EV Station by MIDA Power represents the vanguard of high-power electric vehicle charging technology. Designed specifically for heavy-duty logistics, highway transit corridors, and ultra-fast urban charging hubs, this system delivers a constant 400kW output, enabling high-capacity EV batteries to recharge in minutes rather than hours. The integration of advanced liquid-cooling technology in both the power modules and the charging cables allows for sustained 500A current delivery without thermal throttling, a critical requirement for Class 8 electric trucks and next-generation passenger EVs.

Core Advantages

The MIDA 400kW DC EV Charger Dual Port | 500A Liquid Cooled Unit is engineered to provide a seamless and reliable charging experience in the most demanding commercial environments.

1. Next-Generation Liquid Cooling Technology

Thermal management is the most significant challenge in high-power DC charging. MIDA’s proprietary liquid-cooling system circulates specialized coolant through the charging cables and connector pins, maintaining optimal temperatures even at continuous 500A loads. This prevents the “tapering” effect common in traditional air-cooled systems, ensuring that a 400kW session actually stays at 400kW for the duration of the charge.

2. Dual-Port Efficiency and Dynamic Load Balancing

Equipped with two liquid-cooled CCS2 charging guns, the station can serve two vehicles simultaneously. Our intelligent power distribution algorithms ensure that energy is allocated dynamically based on the state-of-charge (SoC) and battery management system (BMS) requests of each connected vehicle, maximizing throughput and reducing wait times at high-traffic locations.

3. Smart Grid and OCPP Integration

The Smart 400kW DC Fast Charging Station | 1000V Liquid Cooled EVSE is fully compatible with OCPP 1.6J and the latest OCPP 2.0.1 protocols. This allows for seamless integration with global charging network operators, enabling remote monitoring, dynamic pricing, user authentication via RFID or App, and over-the-air (OTA) firmware updates. The system is also V2G (Vehicle-to-Grid) ready, supporting future energy arbitrage and grid stabilization services.

4. Industrial-Grade Reliability and Safety

Safety is paramount in 1000V DC systems. The MIDA 400kW charger features a multi-layered protection architecture, including Type A + 6mA DC leakage protection, overvoltage/undervoltage safeguards, short-circuit protection, and advanced insulation monitoring. The IP54-rated metal enclosure and IK10 impact resistance ensure durability in harsh outdoor conditions, from extreme heat to arctic cold.
