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
