What is a Mobile DC Fast Charger?
A mobile DC fast charger is a portable charging device integrating a large-capacity energy storage battery, a DC charging module, an intelligent energy management system, and a mobile chassis. It can store electricity in advance and discharge it off-grid, providing DC fast charging services for new energy vehicles without relying on a fixed power grid or civil construction.
Its core difference from fixed energy storage charging piles lies in its flexible relocation and lack of infrastructure requirements; compared to ordinary DC fast chargers, it has its own energy storage unit, alleviating grid pressure; and when the grid capacity of a 120KW charging station is insufficient, it can serve as an emergency energy supplement, achieving the triple value of “energy storage + fast charging + mobility.”


Working Principle of Mobile DC Fast Charger
The operation of a mobile DC fast charger consists of four core stages: energy storage, voltage stabilization, fast charging, and safety management.
- Energy Storage Stage: Connected to 220V/380V mains power or photovoltaic power, the AC-DC module converts the AC power to DC power, which is then stored in the lithium iron phosphate battery pack. The BMS system balances the cells and protects the battery.
- Energy Dispatch: An integrated EMS energy management system supports off-peak electricity price energy storage and peak-hour discharge, reducing electricity costs and mitigating the impact of high-power charging on the power grid.
- Fast Charging Output: During charging, the DC power from the battery pack is regulated by the DC-DC module, outputting a DC fast charging current adapted to the vehicle, directly replenishing the power battery without the need for an onboard charger.
- Intelligent Protection: Real-time monitoring of voltage, current, temperature, and insulation status; millisecond-level power cut-off in case of abnormalities; supports multiple protections against overvoltage, overcurrent, leakage, lightning strikes, and overtemperature.
Simply put, it’s a “giant mobile power bank” for new energy vehicles, and also a freely deployable micro off-grid charging station.

Core Features of Mobile DC Fast Charger
- Grid-Free Deployment: No transformer capacity expansion or civil engineering work is required. It can be quickly deployed to highway service areas, scenic spots, construction sites, and event venues, filling coverage gaps left by traditional 120kW charging stations.
- Peak Shaving and Valley Filling, Reducing Operating Costs: Storing electricity during off-peak hours and discharging during peak hours can save 15%–30% on average annual electricity costs per station, while also alleviating grid overload during peak hours and adapting to areas with weak grids.
- High DC Fast Charging Efficiency: Equipped with a DC charging module, it can replenish 60%–80% of the energy in 30 minutes, with performance comparable to fixed DC fast chargers, meeting the turnaround needs of operational vehicles.
- High Protection Rating and Strong Environmental Adaptability: The entire unit is IP54–IP65 waterproof and dustproof, and can operate stably in temperatures ranging from -30℃ to 55℃, supporting long-term outdoor use.
- Multi-functional and highly expandable: It can also be used as an emergency power source and a reverse power supply. Some models support photovoltaic access, realizing the integration of photovoltaic, energy storage, and charging, which is in line with the dual-carbon policy.
