Novel battery management system suitable for mixed power automobile

The invention relates to a novel battery management system suitable for a mixed power automobile, which comprises a central management module, diagnostic equipment, a monitoring computer and a temperature sensor detecting a battery. The battery management system can measure the voltage of a battery module, the total voltage of a battery pack, the working current of the battery and the temperature of the battery with higher accuracy, and can also complete the real-time detection of the insulation performance of the battery pack, carries out data analysis and fault judgment on the collected working data of the battery according to a preset fault threshold value, carries out comprehensive analysis according to the protection requirement of the battery and the control requirement of the whole automobile, gives out the early-warning and warning information of the battery system and reflects the working data of the battery, the early-warning and warning information and the self working state of the battery management system to vehicular equipment in real time by a CAN bus which carries out data exchange with the whole automobile. The diagnostic equipment can be carried along with the automobile, which is greatly convenient to diagnose the working state of the battery.
