The invention aims to provide a reliable
hybrid vehicle battery
fault management system and a management method thereof. The
management system comprises a
vehicle control unit, a battery controller, a motor state monitoring module, a
battery voltage monitoring module, a battery current monitoring module, a battery
temperature monitoring module, a battery insulation monitoring module, a
high voltage precharge monitoring module and a battery
equalization monitoring module, and a
high voltage loop
interlocking monitoring module, wherein the motor state monitoring module, the
battery voltage monitoring module, the battery current monitoring module, the battery
temperature monitoring module, the battery insulation monitoring module, the
high voltage precharge monitoring module and the battery
equalization monitoring module are connected with the vehicle controller; the high
voltage loop
interlocking monitoring module is connected with the battery controller; the battery controller is connected with the vehicle controller and the
relay controlling the on and off of a battery high
voltage loop; and the vehicle controller is also connected with a fault prompt unit. The
management system carries out treatment according to different battery faults and the operation conditions of a motor, ensures the safety of driving and drivers and passengers, improves the safety of a
battery system and the service life of the
battery pack and makes the whole
battery system more reliable.
