The invention relates to a fault detection system based on a power battery management system, comprising a fault detection module and a communication module, characterized in that the fault detection module is connected to the communication module through an MCU main control module, and the fault detection The detection module includes the following features: a charging surge protector located between the charging device and the power battery pack; a battery current sensor for detecting the current at the output terminal of each power battery; a voltage sensor and a circuit temperature at each circuit connection terminal Inductors; battery temperature sensors arranged on the output terminals of each power battery; radial vibration sensors arranged on the body of the cooling fan; cooling fan current sensors used to detect the current at the connection end of the cooling fan circuit. The present invention provides a fault detection system capable of displaying each fault in detail, which is beneficial for subsequent troubleshooting and positioning of each fault and maintenance of the vehicle power battery management system.
Description
technical field [0001] The invention relates to the field of automobile batteries, in particular to a fault detection system based on a power battery management system. Background technique [0002] At present, with the increasingly scarce oil resources in the world and the pollution problems caused by them, major international and domestic automobile manufacturers are committed to the development of new energy vehicles to advocate energy saving, emission reduction and sustainable development; Driven by new energy vehicles, it has increasingly become the mainstream choice of major car companies. The power battery is one of the most core components in the "three major batteries" of new energy vehicles, so the fault detection of the power battery and its circuit is particularly important. In the prior art, the BMS (power battery management system, or Battery Management System) transmits the detected faults through CAN (Controller Area Network, controller area network bus) com...
