Remote monitoring technology research and platform development for electric vehicle

Aiming at improving the operation security of electric vehicle (EV) and revealing the influence of design parameters on vehicle performance, a remote monitoring platform is designed and developed. Based on GPS data, the platform fulfills the real-time positioning for vehicle by means of projection and curve fitting. With the fault diagnosis of power battery for EV as example, a method for battery state and fault monitoring is put forward based on the principle of threshold and using QTouch development platform and Matlab software. A real vehicle testing on the platform developed is conducted with typical urban driving cycle. The results indicate that the platform can realize the accurate collection and monitoring for the remote data of EV, perform real time fault diagnosis for various assemblies of vehicle and give warning, and can also conduct the performance analysis and evaluation of EV, meeting the requirements of the remote monitoring and management of EV. ©, 2015, SAE-China.
