3. Install a magnetic powder brake at the output end of the transmission shaft to simulate the vehicle load system. By adjusting the load size at both ends, the changes in parameters such as current and voltage of the electric drive transmission system under different operating conditions (starting, acceleration, constant speed, deceleration, parking, climbing, etc.) can be realistically reproduced.
4.Installation of power battery pack with CAN-BUS communication battery management system.
5. The power battery is charged using a car charger with CAN-BUS communication.
6.Equipped with a motor controller upper computer, it can accurately detect changes in brake energy feedback current and master the concept of brake energy recovery.
7. The equipment is equipped with a 12V power grounding mechanical switch, which can disconnect the 12V grounding at any time and cut off the entire system power supply.
8. Equipped with safety protection devices such as protective covers.
9. The UV flat printing panel fully displays the working principle diagram of the electric drive transmission system, and is equipped with detection terminals. With the help of a multimeter and oscilloscope, it can detect parameter changes in various states in real time.
10. The equipment consists of a mobile platform and a panel, with the platform placed horizontally and the main components installed; Four casters are installed at the bottom of the equipment for flexible movement, and the casters are equipped with self-locking devices to fix their positions.
11.There is a 20cm steel tabletop on the base in front of the equipment detection panel, which is convenient for placing data, testing instruments, etc.
12. The equipment is equipped with an intelligent fault setting and assessment system. Teachers set faults, and students analyze and locate the fault points. The main components are led out of the testing port and directly tested at the fault location, mastering the ability to handle real vehicle faults.
