Product Description

Device overview
This training platform adopts the lithium iron phosphate power battery produced by vehicle mass production. The nominal voltage of the single battery is 3.2V, the capacity is 20Ah, and the battery is safe and stable. The power battery pack adopts 23 single cells in series, and the rated voltage of the battery pack is 73.6V. It can dynamically monitor the total battery voltage, current, temperature and the voltage of each single battery cell, and at the same time realize the battery pack SOC estimation, effective charge and discharge control and fault alarm. Function. It is suitable for the testing and maintenance training teaching of BMS lithium battery management system training bench in vocational and technical colleges, general education colleges and training institutions.

2. Features
1. The system consists of lithium iron phosphate battery module, battery management system (BMS), intelligent vehicle charger, DC/DC module, high voltage control module (charging relay/discharging relay/precharge relay/maintenance switch MSD/Hall current sensor ), three-speed ignition switch, 10-inch touch screen, national standard charging gun with socket, 12V battery, 5-speed adjustable analog load, etc.
2. The system is equipped with a 10-inch touch screen, which can observe the battery pack voltage, current, temperature, SOC and other information, and can read the BMS system parameters through the touch screen to modify the system parameters, simulate the system's primary and secondary alarms and Protection and other information change status, touch screen to wake up/sleep autonomously, saving energy.
3. The system is equipped with a simulated load (discharge instrument)/simulates the discharge process of the real vehicle through the simulated load. The BMS dynamically monitors the discharge process, collects the discharge current, and displays it dynamically through the touch screen, and the discharge current can be adjusted through the load switch.
4. The system is equipped with a simulated load. The simulated load simulates the discharge process of the real vehicle. The BMS dynamically monitors the discharge process, collects the discharge current, and displays it dynamically through the touch screen. The discharge current can be adjusted through the load switch.
5. The upper cover of the power battery box is designed with a transparent acrylic plate, which clearly shows the circuit connection of the power battery pack. Each battery is marked with the corresponding serial number, and the line collection line is marked with a wire; the connection method of the collection line can be intuitively understood, and the battery pack can be checked by a multimeter. voltage is measured.
6. The system is equipped with an intelligent on-board charger. The charger communicates with the BMS through the CAN protocol. After connecting the charging gun, the system self-checks and the charging positive contactor is closed. The charger performs constant current charging according to the BMS status information, and the BMS performs real-time charging. Online Monitoring.
7. The system is equipped with emergency stop switch and protection device, which is convenient to cut off the main power supply and carry out safety protection;
8. Detailed color circuit diagrams and schematic diagrams of components meet the teaching needs of control system circuits, component names, etc., and lay a solid foundation for analysis, detection, diagnosis, troubleshooting and assessment of control systems.
9. The control panel is equipped with an external detection terminal, which can detect the electrical signals of each sensor, actuator, etc., such as resistance, voltage, current, frequency signal, etc., in the non-destructive wiring harness.
10. Equipped with appropriate safety protection measures to ensure the safety of teaching.
11. The bench adopts an all-aluminum alloy frame structure, which is beautiful in appearance, atmospheric, and dirt-resistant. It has a self-locking caster device, which is flexible, safe, reliable, and durable.
12. The teaching panel and control panel are made of 4mm thick aluminum-plastic panel, which is resistant to corrosion, shock, pollution, fire and moisture;
13. The training bench uses blue borders to distinguish it from traditional fuel teaching equipment.
14. The protective cover of the training platform is made of acrylic transparent material, so that the internal components of the internal structure of the training platform can be seen at a glance
