Electric Motor-Cycle Drive Tester

The project of producing an electric motorcycle tester device is defined to test and evaluate the ECU board manufactured by Innowatt Company after the initial assembly stage. The mentioned ECU board has a control unit and a drive unit, which in the control section provides the connection between various parts of the motorcycle, such as batteries, a speedometer, an immobilizer, and a motor that rotates the rear wheels and in the drive unit, three-phase power of about 5 kW is connected to the motor. In addition to two terminals for connecting batteries, this ECU has 3 output terminals for voltage injection and 24 general-purpose input/output pins, 10 communication input/output pins, and 6 pins for connecting to the speed sensor. The tester board is designed in such a way that it has access to all the inputs and outputs of the control unit and the drive unit and can evaluate it with its own special process and transfer the accuracy or inaccuracy of the assembled board's operation to the computer through the UART communication. The hardware part of the tester device consists of a processor based on stm32feb IC, a power supply with 12-volt dc input, 7 electronic relays, and their controller IC and other necessary circuits for testing the ECU. In addition to the above sections, there are two UART peripherals to connect the two boards to each other and the tester board to the computer, and the necessary pins for programming the ECU board and the module on it are also established on the tester. The software part based on embedded C is currently being developed and 80% of its work has been completed.
