Detailed explanation of key components of OBC

The key components of OBC include power circuit, control circuit, input and output ports and wiring harness. As the core of energy conversion, the power circuit is mainly composed of semiconductor devices, magnetic devices and switch interface devices. The control circuit is the "brain" of OBC, which collects parameters such as voltage, current, temperature and so on in real time during the charging process through sensors, and sends control signals to the power circuit according to the battery status and charging requirements.
