Referring to Fig. 1, Fig. 1 is a kind of theory diagram for electric automobile 100 that embodiments of the invention provide.It is described electronic
Automobile 100 includes battery management system 10, battery pack 20, vehicle management system 30 and high voltage electric equipment 40.The battery
It is the high voltage electric equipment 40 that management system 10, which is used to control the battery pack 20 when electric automobile 100 needs high-tension electricity,
Power supply, in addition, the battery management system 10 can also be used to gather the battery pack in real time in 20 discharge and recharge of battery pack
The battery information of each cell in 20, the battery information calculating battery pack according to each cell collected
20 state of charge, the charged state of the management battery pack 20 and failure predication etc. is carried out to the battery pack 20, wherein,
The battery information includes voltage, electric current and temperature information.The battery management system 10 includes main control module 1, emergency use
Module 2 and relay 3, the battery pack 20 are made up of the cell of multiple series connection and/or parallel connection.The main control module 1
It is connected with vehicle management system 30 by communication bus, particular by CAN (Controller Area Network, controller
LAN) bus is connected, and the vehicle management system 30, which is used to sending electricity when electric on the electric automobile 100 needs, to be referred to
Make to the main control module 1.First end of the main control module 1 also with the relay 3 is connected, and the second of the relay 3
End is connected with the battery pack 20, and the 3rd end of the relay 3 is connected with high voltage electric equipment 40.The main control module 1 is
The Central Control Module of the battery management system 10, it is corresponding for being sent according to the upper electricity instruction of the vehicle management system 30
Control signal control the relay 3 to close, and then control the battery pack 20 to be powered for the high voltage electric equipment 40.
The emergency use module 2 include detection unit a, control unit b and alarm unit c, the detection unit a with
