Function:
The main function of an OBC is to convert alternating current (AC) to direct current (DC) to charge the power battery of an electric vehicle. Specifically:
Charge control: It can adjust the charging current and voltage according to the battery's status and requirements to achieve a safe and efficient charging process.
Communication function: It communicates with the vehicle's battery management system (BMS) and external charging equipment to ensure the safety and stability of charging.
Protection function: It has protection functions such as overvoltage, overcurrent, and overheating to prevent damage to the vehicle and battery during charging.
