The power consumption of traditional vehicle will also cause environmental pollution, which leads to the

5、accelerated development of new energy vehicle. The decrease of energy has also triggered the reform of vehicle power. Consequently, the replacement of traditional gasoline with electric energy in vehicle has entered the publics vision with its limited pollution and influence on the surrounding envir

6、onment. The primary characteristic of electric vehicle lies in its battery engineering, and the system of battery management also becomes a hot topic in the existing research. As an indispensable part of electric vehicle, battery management system plays a critical role in battery management, charge-

7、discharge control and battery monitoring, etc.It is planned that the design requirements and main body design planning of Chinese Changan electric vehicle should be taken as the blueprint in the design of a battery management system which takes C8051F040 single-chip microcomputer as the primary cont

8、roller. It is hoped that the comprehensive detection and management of the battery can be realized through this design. The design mainly includes the selection of the single chip for the battery management system, as well as the detection of voltage, current, battery charging and discharging for ci
