Abstract

The invention provides a battery management system of an electric automobile. The battery management system comprises a monitoring module, a central processing unit and a control module. The monitoring module is used for monitoring a state of a battery pack and a state of the battery management system in real time, and sending abnormal condition data of the battery pack and / or the battery management system when the states / state of the battery pack and / or the battery management system are / is abnormal. The central processing unit is used for generating a control instruction according to the abnormal condition data of the battery pack and / or the battery management system. The control module is communicated with the monitoring module and the central processing unit and is used for sending the condition data of the battery pack and the battery management system to the central processing unit and controlling the battery management system according to the control instruction. The battery management system can timely master the abnormal operation state of batteries, give full play to performance of the battery pack and provide maximum protection for the battery pack, and can monitor an operation state of the battery management system, timely feed back abnormal states of systems, take protective measures and improve the safety performance of the electric automobile.

Description

technical field [0001] The invention relates to the field of automobile electrical technology, in particular to a battery management system of an electric vehicle. Background technique [0002] With the emergence of the energy crisis, clean and environmentally friendly electric vehicles have received more and more attention. As the core component of electric vehicles, the power battery is of great significance to manage it. [0003] The battery management system is an important means to guarantee the working performance of the power battery. The battery management system maximizes the performance and life of the battery, fully guarantees the operating performance of the battery, and at the same time protects the battery. [0004] The problem existing in the existing battery management system is that the response is delayed, which cannot meet the purpose of real-time monitoring of the battery system and increases the possibility of accidents.
