On-Board Battery Charger

The on-board battery charger is a DC charging device mounted inside the electric vehicle, and transfers an AC input into a DC output to supply a reliable charge to your EV.

The on-board charger is designed with a wide DC output range of 200VDC-450VDC, 250VDC-650VDC and 300VDC-750VDC (adjustable) to meet various voltage and charging requirements.

The on-board charger allows users to charge their electric vehicle so long as there is a reliable power socket, because it is a movable charging pile that features a compact structure, an excellent cooling performance, and outstanding insulation effects.

Applications

Applicable for all types of electric vehicle on-board DC charging.

Advantages Wide input voltage range: 90V-264V, designed with input surge protection, and each charger module has power of 3.3kW, 6.0kW or 20kW The system uses DSP (digital signal processing) control technology, and is 100% numerically controlled from input to output Input THDI < 3%, input power factor reaches 0.99 and overall efficiency reaches 95% and above; Wide output voltage range: 200-750VDC (adjustable): suitable for meeting different charging requirement voltage demands Low DC ripple causes minimal effects on battery lifespan Standard CAN communication interface configuration allows for easy data transferring with external devices. The on-board battery charger is equipped with input overvoltage protection, undervoltage alarming, output overcurrent and short circuit protection functions; The on-board battery charger is equipped with a 13.8VDC auxiliary power supply to support the BMS (battery management system).
