1. It is located in the front cabin, which can convert the direct current from the battery pack into alternating current to drive the motor, and convert the alternating current generated by the motor into direct current under braking and other working conditions to feed back to the battery pack. It can control the vehicle forward and backward, acceleration and deceleration, discharge feedback and other various working conditions, and is one of the important controllers of the whole vehicle's high-voltage system.
2. BYD's latest electronic control technology is four in one. High-voltage electric control assembly includes motor controller module, car charger module, DC-DC converter module, and high-voltage distribution module, which simplifies the connection between the units, with better performance and more reliable use. Compared with other domestic new energy pure electric vehicles, it stands in the forefront of new energy electronic control technology.
3. The four-in-one high-voltage electric control assembly is transparent and refit, installed on the turntable frame, and can be fixed at any position for students to understand and disassemble. It is equipped with 2 special clamp-type digital multimeters for electric vehicles, which are used for on/off circuit and component parameter measurement. The supporting courseware of the training platform describes the components composition, disassembly method, matters needing attention in high-voltage safety, and control logic in different states of BYD E5. (▲ The FLASH power system logical demonstration is provided on site, fully demonstrating the control principle of BYD E5 pure electric vehicle, including stopping state, power on process, EV working state, braking energy feedback, parking 220V AC charging, parking 380V AC charging, parking DC charging, A/C compressor working, PTC heating module operation, and power leakage state. There are a total of 10 states, the demonstration is smooth, and it needs to use the intelligent switch in a diagram to change the state. The FLASH surface is intelligent. Click to automatically display the introduction of main parts, including power battery pack, positive electrode contactor, negative electrode contactor, 1 battery pack voltage divider contactor, 2 battery pack voltage divider contactor, high-voltage electric control assembly, MG drive motor, DC charging port assembly, AC charging port assembly, PTC heating module, and A/C compressor.)
