    The on-board charger of a pure electric vehicle or a plug-in hybrid vehicle is a DC charging device whose voltage is the same as that of the battery matched with the original vehicle. According to the control commands of the battery management system, the charging current and voltage parameters are dynamically adjusted to complete the electric charging. The core component of the car charging process. As a power electronic system, the on-board charger is mainly composed of a power circuit and a control circuit. The power circuit is composed of AC rectifier, transformer and power tube, and the DC/DC converter is an important part of it. The control circuit realizes serial communication with the power management, and controls the power drive circuit to output a certain voltage and current according to requirements. Usually for OEMs, the requirements of on-board chargers are low cost, small size, light weight, long life, high reliability and high safety. The current mainstream on-board chargers are generally 3.3kw and 6.6kw.

The basic principle of car charger

Generally there are the following interfaces:

1) AC input: connect the connector coming in from the AC charging socket

2) DC output: the part that the car charger outputs to the battery

3) Low-voltage control interface: low-voltage interface between the on-board charger and the BMS and external connections

    As a power electronic system, the on-board charger is mainly composed of a power circuit and a control circuit. For the power circuit, the DC-DC converter composed of the transformer and the power tube is an important part; for the control circuit, its core is the controller, which is used to realize CAN communication with the BMS, collect and analyze the state of the battery. Judgment, and then adjust the charging parameters of the charger and control the power circuit to charge the lithium battery pack according to the three-stage charging curve.
