Pure electric vehicles

as an energy-saving and environmentally friendly means of transport

has be- come a hot topic in the world. However

pure electric car endurance is an important factor

in the process of devel- opment of electric vehicles. For electric vehicles in use due to the restrictions and the impact of environmental fac- tors

battery power

resulting in electric vehicle endurance short questions. The author based on the principle of e- lectric cars using BP neural network technology

and suggest a new BP neural network charging and discharging control strategy

through analysis of electric vehicles and electric vehicles driven strategy mode. In order to validate the proposed control strategy is reasonable

we have established vehicle simulation platform using LabVIEW soft- ware. Through simulation experiments validates the control strategy based on BP neural network rationality

and a- chieves improved electric car endurance purposes.
