MIDA 420kW 560kW Ultra Fast Liquid Cooled DC Charger 800V Battery Buffer Grid Friendly for Fleet Hub

The MIDA 420kW 560kW Ultra Fast Liquid Cooled DC Charger is a battery-buffered, grid-friendly charging station engineered for fleet hubs with limited grid capacity. Integrating a BESS battery buffer with liquid-cooled ultra-fast power modules, this DC fast charging station delivers peak 800V charging speeds while drawing smooth, capped power from the grid to avoid costly service upgrades.

Core Advantages

Integrated Battery Buffer – An onboard BESS stores energy during low-demand periods and discharges during charging peaks, enabling high output on a constrained grid connection.
Grid-Friendly Operation – Peak shaving and smooth power draw reduce demand charges and eliminate the need for expensive transformer or feeder upgrades.
800V Ultra-Fast Liquid Cooling – Liquid-cooled cables and modules sustain 500A+ current for rapid charging of 800V fleet vehicles without thermal derating.
Scalable Fleet Power – Selectable 420kW and 560kW output over a 200V-1000V range serves mixed fleets of vans, trucks, and passenger EVs.

Application Scenarios

This 420kW 560kW battery-buffered liquid-cooled DC charger is ideal for fleet hubs, logistics depots, and commercial sites with limited grid capacity that still require ultra-fast turnaround. The integrated BESS buffer enables high-power charging where the utility connection alone would be insufficient, cutting demand charges while supporting rapid 800V fleet operations.

After-Sales Advantages

MIDA provides a comprehensive warranty, global spare-parts support, remote diagnostics through its cloud platform, and full site engineering documentation covering both charger and battery buffer. As a manufacturer with over a decade of experience in EV charging and energy storage, MIDA supports OEM/ODM customization of buffer capacity, power output, and connector standards for fleet-hub deployments.

Frequently Asked Questions (FAQ)

What is a BESS-integrated DC charging station?

A BESS (Battery Energy Storage System) integrated DC charging station combines a fast charger with on-board lithium battery storage. The battery buffers energy from the grid or solar, so the station can deliver high charging power even where the grid connection is limited.

How does peak shaving lower charging costs?

The BESS charges its internal battery during off-peak, low-tariff periods and discharges it during peak demand. This peak-shaving strategy reduces expensive demand charges and lets the station output more power than the grid connection alone would allow.

Can the storage charging station run on solar and off-grid?

Yes. Solar-BESS and microgrid models integrate photovoltaic input with battery storage for off-grid or grid-constrained operation, ideal for remote depots, fleet hubs and sites awaiting grid upgrades.

What is the storage capacity and how is it configured?

Storage capacity is modular and configured to the site load profile (for example 215kWh and above). MIDA sizes the battery, PCS and charger power together so the system matches daily energy throughput and peak-power targets.

Which management protocols does the BESS charger support?

The BESS DC charger supports OCPP 2.0.1 for charging management plus an energy-management system for storage, solar and grid coordination, demand response and remote monitoring.

What warranty and support come with the BESS system?

MIDA provides a full warranty on the charger and storage system, global spare parts, remote diagnostics and lifecycle technical support, protecting the investment across the full deployment.
