A Vehicle Energy Management System for a Battery Electric Vehicle

The prospect of a decreasing supply of fossil energy sources necessitates the search for alternative ways of individual transport. An important step is the electrification of the drive train and further vehicle components, enabling a total control of the overall energy flow while at the same time offering more degrees of freedom in optimizing the vehicle architecture. The current status of the development of a vehicle energy management for a single source Battery Electric Vehicle is presented. A central ECU, a bench test system and a simulation model were developed. The energy management strategy presented can help to improve the lifetime of EV's batteries, which finally needs to be evaluated in vehicle prototype tests.
