Tiivistelmä
This thesis covers an electric powertrain testbench development with PC-based control system for battery system testing commissioned by IONCOR Oy. This thesis report focuses on the PC-based control system, which was done using Vector CANoe on CAN bus. The objective of this project is to produce a working testbench with a control system ready for battery system testing.
First, the batteries, inverters and motors used in the testbench are introduced. After that, CAN bus, CANopen protocol, and CANoe are explained before presenting the development process of the control system. Lastly, the testbench development and testing during this project is demonstrated.
The system parts were tested independently constantly throughout the project before the whole system was assembled. Interference and compatibility problems were found during the project, which were a good to find and solve. The functional safety diagnostics in the battery pack sensed the noise level induced by the inverters when motors were idling and intermittently triggered a spurious fault condition. The testbench will be used for battery testing with present and future IONCOR battery products.
The project in whole was a success and produced a working testbench with a control system ready for testing.
