Inverter CAN communication control
Achieved the elimination of double operation and automation of testing through inverter CAN communication control.
The company introducing this case study is a manufacturer developing drive units for electric vehicles in Japan. They are engaged in the development and evaluation of motors and inverters for EVs, and there was a demand for advanced performance verification using dynamometer testing machines. Within this context, there was a request to link the inverter, which is the test specimen, with the testing machine, sending command values from the testing machine side via CAN communication for integrated control. In the evaluation field for motors and inverters for electric vehicles, speed or torque was input from the testing machine side, and load tests for the inverter and motor were conducted. However, in the conventional testing environment, it was necessary to operate the inverter on the test specimen side and the testing machine side using separate PCs, leading to the complexity of setting, starting, and monitoring individually. It was burdensome for the site to have to operate two PCs back and forth for each test. At SeaGoTo Co., Ltd., in order to integrate the control systems that were separated between the testing machine side and the test specimen side for load testing of motors and inverters for electric vehicles, a modification of the control system utilizing CAN communication was implemented.
