The Role of On-board Chargers in Electric Vehicles

The On-board Charger （OBC）is a charger that is fixedly installed in an electric vehicle, which has the ability to safely, quickly and conveniently fully charge the power battery.

OBC is mainly divided into two main parts, the power supply part and the main board of the charger control. The main function of the power supply is to convert AC power into DC power required by the power battery, and the main board of the charger control is to control the power supply, protect it, and communicate with the external network. The main board of the charger is to control, protect and communicate with the external network, etc. EMPevmobility develops and produces On-board Chargers that use the most efficient CAN high-speed network available to run communications.

Electric car on board charger is a key component that affects charging power and efficiency, and its technological development promotes the popularization and practicalization of electric vehicles. The output power of On-board Chargers equipped with mainstream electric vehicle passenger cars on the market are 3.3KW and 6.6KW.
