Abstract

The invention relates to a control method for a power battery and its circuit fault detection system, which is characterized in that it includes the following steps: (1) the MCU main control module sets the value limit value of the power battery measurement information; (2) the fault detection module measures the corresponding Power battery data, and transmit the detected data to the MCU main control module; (3) compare the power battery data measured by the fault detection module with the corresponding measurement information value limit value set in the MCU main control module; (4) The MCU main control module judges whether the power battery and its circuit are faulty according to the compared information. If the power battery and its circuit are faulty, it will be sent to the terminal through the communication module. The invention provides a power battery and its circuit fault detection system capable of displaying each fault in detail, which is beneficial for subsequent troubleshooting, location and maintenance of the vehicle.

Description

technical field [0001] The invention relates to the field of automobile batteries, in particular to a power battery and a control method for a circuit fault detection system thereof. 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 ne...
