Simulation system of the performance of power battery for electrical vehicle based on Internet of things

Aiming at the uncertain problem of dynamic performance evaluation of power battery for electrical vehicle, this paper researched deep on the establishment of simulation system of the performance of Li-on power battery for electrical vehicle in different working conditions by comparing and analyzing the general structure of simulation system of the performance of electrical vehicle in and abroad combined with the characteristic of pure electrical vehicle, and proposed an on-line performance simulation method of Li-on power battery for electrical vehicle based on the technology of Internet of things. Design for data acquisition, hardware simulation of charging and discharging of the simulation system and the running state monitoring for simulation platform are also included in this paper. It is of most importance for the development of electrical vehicle and Li-on power battery system for electrical vehicle of our country.
