Abstract

The invention discloses a power battery fault display method and device. The power battery fault display method comprises the following steps: a BMS(battery management system) detects whether a battery system has faults, fault flags are encoded, codes are integrated into an array, fault information is formed, and fault recording is performed; the fault information is sent; the fault flags are queried according to fault codes; the fault flags are displayed. The faults can be positioned precisely, later checking and positioning of each fault are facilitated, and vehicle maintenance is facilitated.

Description

technical field [0001] The invention relates to the technical field of electric vehicle battery systems, in particular to a power battery fault display method and a power battery fault display device. Background technique [0002] At present, as the world's oil resources become more and more scarce and cause pollution problems, major international and domestic automobile manufacturers are committed to vigorously developing new energy vehicles to advocate energy saving, emission reduction and sustainable development; and power batteries The new energy vehicles driven by automobiles are increasingly becoming the mainstream choice of major car companies. [0003] The power battery is one of the most core components in the "three major electric vehicles" of new energy vehicles. The power battery management system (hereinafter referred to as BMS, or Battery Management System), as the monitoring and management center of the power battery, must monitor the battery pack. Real-time ...
