Abstract

The invention discloses and provides a breakdown diagnostic system of a power battery. Firstly, a status signal of the power battery is collected through a signal collecting module. Secondly, the collected status signal of the power battery by the signal collecting module is analyzed by a breakdown diagnostic module. The breakdown is divided according to the preset breakdown types and breakdown grades when the signal is confirmed to be a breakdown signal, thus the breakdown of the power battery is obtained in time. Further, preset controllable breakdown of the existing breakdown is effectively processed according to the types and the grades of the breakdown by a breakdown processing module, thus an existing regular operation of a whole vehicle is guaranteed. Output power of the power battery is limited by the power battery controlling module according to the types and the grades of the breakdown processing module, thus safe operation of the power battery is guaranteed.

Description

technical field [0001] The invention relates to the field of power batteries, and more specifically relates to a fault diagnosis system for power batteries. Background technique [0002] Due to the scarcity of oil resources and the pollution of the environment, traditional power vehicles can no longer meet people's requirements. With the wide application of electronic technology in vehicles, hybrid vehicles and pure electric vehicles have developed rapidly, such as electric vehicles. [0003] As the main component of hybrid vehicles and pure electric vehicles, the safety and reliability of power batteries are directly related to the safe driving of people and vehicles. However, at present, electric vehicles such as electric vehicles cannot actually obtain the status information of the power battery in a timely manner. When the power battery fails, the failure information cannot be obtained in time, and the failure cannot be processed first, thus affecting the normal operati...
