The research on intelligent management system of li-ion power battery string of electric vehicle

Entering the 21st century, the energy shortage seriously restricts the development of human society. Lithium battery with high monomer voltage and high energy density has become the first choice of future power battery. In order to provide electric cars with safe and reliable power sources, this paper put forward an overall design scheme of the battery energy management system. Firstly, according to the requirement of battery management system, the hardware and software of the PC and the monitoring module ware designed. Secondly, in order to meet the needs of battery equilibrium, the charge balance control strategy was proposed. Finally, the battery group was introduced, and a viable battery grouping scheme in engineering was presented. Through practical test, the battery energy management system could effectively manage the power of lithium-ion battery.
