The on-board charger can balance the internal and external pressure difference to avoid the accumulation of foreign objects, water, oil, dust, etc; Waterproof and breathable to prevent water vapor from entering the cavity and change the structure of the motor, which can not be fundamentally solved by designers in the past; It is easy to install. It can be solved by opening a hole on the shell or accessories and screwing in; Extend the service life of the motor.
1. It has the function of communication between high-speed can network and BMS to judge whether the battery connection state is correct; Obtain battery system parameters and real-time data of the whole group and single battery before and during charging.
2. It can communicate with the vehicle monitoring system through the high-speed can network, upload the working status, working parameters and fault alarm information of the charger, and accept the start charging or stop charging control command.
3. Complete safety protection measures
AC input overvoltage protection function; AC input undervoltage alarm function; AC input overcurrent protection function; DC output overcurrent protection function; DC output short circuit protection function; Output soft start function to prevent current impact; It has flame retardant function.
4. During charging, the charging function ensures that the temperature, charging voltage and current of the power battery do not exceed the allowable value; It also has the function of limiting the voltage of single battery, and automatically adjusts the charging current dynamically according to the battery information of BMS.
5. Automatically judge whether the charging connector and charging cable are correctly connected. When the charger is correctly connected with the charging pile and the battery, the charger can start the charging process; When the charger detects that the connection with the charging pile or battery is abnormal, stop charging immediately.
6. The charging interlock function ensures that the vehicle cannot be started before the charger and power battery are connected separately.
7. High voltage interlock function, when there is a high voltage endangering personal safety, the module locks without output.
8. The advantage of the on-board charger is that no matter the on-board battery needs to be charged at any time and anywhere, the electric vehicle can be charged as long as there is an AC socket with the rated voltage of the charger. The disadvantages of on-board charger are limited by the space of electric vehicle, small power, small output charging current and long battery charging time.
