5. Provide a test platform for scientific research in electrical engineering and power systems.

 

2. Technical parameters

 

The power supply and distribution technology experimental device includes the following core components: a wiring system, measuring meter, multi -function microcomputer protection device, compensation capacitor group, short -circuit settings module, conventional relay, characteristic test signal system, etc.

 

The entire experimental system control power supply (including relay auxiliary voltage) uses a DC 24V power supply within a safe voltage. The experimental signal requirements are required to output in accordance with the second standard of the power system, and the output power is strictly controlled to prevent hidden dangers of electric shock.

 

(1) One wiring system for the change of the matching:

 

Simulation 10kV/380V Anti -voltage voltage variable distribution house, including at least 10kV entry lines (of which can be used as a spare power supply), 1 matching and 4th road 380V. Install a short -circuit f--lure setting unit in a wiring system to simulate various faults of the line or equipment.

 

It cont--ns at least 10 three -phase simulation circuit breakers: simulation of three -phase AC contactor. The simulated circuit breaker can perform a split gates through the local manual buttons and the distant remote control. The local button of the simulated circuit breaker with a red and green light indicator (with the light button, the red light indicates the coincide, and the green light indicates the division).

one. Product introduction

The original original pure electric vehicle power battery pack (including the BMS management system) is selected, the original car is installed and the original car control function is installed, and the original high -voltage power distribution box and the vehicle charger are installed.

True showing the connection control relationship, installation location and operating conditions of the core components of lithium iron phosphate power battery packs, the safety precautions of high -voltage system safety, and tr--nees the students' ability to analyze and deal with lithium iron phosphate power high -pressure battery f--lure.

It is suitable for teaching and m--ntenance tr--ning for new energy pure electric vehicle power battery management courses in various types of universities.

two. Features

1. The m--n components are installed on the tr--ning platform to ret--n the electrical connection method of the original car. It can be convenient to disassemble after power off. Tr--ning and disassembling wire beams and electrical appliances, master the m--n points of disassembly and safety protection of high -voltage system components.

2. The battery management system of the original car is composed of battery management controller and battery information collector and power battery sampling line;

3. The battery management controller ret--ns the original car function, such as charging discharge management, contactor control, power control, battery abnormal state alarm and protection, SOC/SOH computing, self -inspection, and communication functions;

4. The battery information collector ret--ns the original car function, such as battery voltage sampling, temperature sampling, battery balancing, abnormal detection of sampling lines, etc.;

5. Power battery sampling line ret--ns the function of the original car, such as connecting the battery management controller and the battery information collector to achieve communication and information exchange between the two.

6. The BMS battery management system ret--ns the function of the original car, such as active equilibrium function, switching control protection (single disconnection, short circuit, overvoltage, under pressure, overcurrent, temperature), communicate with charger CAN, control through BMS control through BMS control, control through BMS control, control through BMS control, control through BMS control, control through BMS control, control through BMS control, control through BMS control, control through BMS control, control through BMS control, control through BMS control, control through BMS control, control through BMS control, control through BMS control, control through BMS control, control through BMS control, control through BMS control, control through BMS control, control through BMS control, control through BMS control, control through BMS control, control through BMS control, control through BMS. The car charging machine work, estimated SOC (load state) and so on.

7. Installing the original car instrument, you can observe various parameters such as the charge and discharge process. Preserve the function of the original car instrument, the control logic of the power battery pack discharge process and the changes of the m--n component parameters.

8. The tr--ning desk provides the tr--ning descendant of other systems such as the driver. The power high -voltage power supply, the original car is equipped with the cable, and the original car connection method is ret--ned.

8. The equipment is equipped with a 12V auxiliary power supply ground mechanical switch, which can quickly cut off the system's high and low voltage power supply.
