This project is intended to proceed with the developement of a battery management system (BMS) in an electric vehicle. The project has been issued from the company Clean Motion AB, and the work took place in a laboratory at Chalmers. In the purpose of being able to connect a set of batteries in parallel in the vehicle, the project examines the possibilities of connecting multiple BMS devices to a CAN bus. This should be done so that the data transmitted on the CAN bus does not collide with other data. Also the software of the BMS has been translated from BASIC to C and nally its features have been tested to verify the correctness.

In the report the reader will nd an analysis and description of the BMS and its software. The reader will also nd a description on how the CAN bus is operating and how the BMS uses it. Thereafter the report evaluates a set of di erent possible solutions for avoiding collision of data on the CAN bus. And how it was nally implemented and tested.

Nyckelord: BMS, CAN, CANopen, I2C
