DR - Electric Scooter Battery Pack Test Bench

1.1 Equipment Overview: The electric motorcycle (e-motorcycle) battery pack test bench is a crucial device for verifying the performance, safety, and reliability of battery packs, covering functions such as discharge current testing, discharge voltage testing, temperature monitoring, etc. 

1.2 Overview of Main Test Functions: 

1.Battery output current test: After installing the battery in the vehicle and starting the vehicle, the battery will output current. A current transmitter is connected in series between the battery and the load end (vehicle motor) to obtain the real-time output current value of the battery and feed it back to the system to draw a characteristic curve of driving speed and current. After the test is completed, a report can be generated and exported. 

2. Battery output voltage test: After installing the battery in the vehicle and starting the vehicle, the battery will output voltage. A voltage transmitter is connected in series between the battery and the load end (vehicle motor) to obtain the real-time output voltage value of the battery and feed it back to the system to draw a characteristic curve of the driving speed and voltage. After the test is completed, a report can be generated and exported. 

3. Driving range: Automatically records the number of kilometers the vehicle travels from a fully charged battery to a completely discharged state. 

4. Speed measurement during driving: The real-time speed of the vehicle is read by the speed sensor installed on the roller and fed back to the system. 

5. Battery temperature monitoring: Several surface mount sensors are adhered to different parts of the battery to monitor changes in the battery's surface temperature. If the temperature is too high, the system will automatically shut down to prevent overheating damage caused by long-term testing. It can also test the linear relationship between battery temperature, speed, current and voltage. 

6. Vehicle load: Apply pressure to the vehicle through cylinders to provide load, simulating human weight. 

7. Battery charging: The device is equipped with a charging plug. Use a charger that matches the battery to charge the battery. When the battery is fully charged, it will automatically disconnect. When the battery runs out of power, an alarm will sound to prompt you to stop the machine and charge it. 

8. Bumpy Road Test: Install obstacles with thicknesses of 5mm, 10mm, and 20mm on the roller to simulate the vehicle driving on bumpy roads. Test the fluctuation trend of the battery's output current and voltage, and simultaneously test the durability and stability of the battery pack under bumpy conditions. 

9. Tire burst emergency stop: A limit switch is installed on the guide light shaft of the load group. When a tire burst occurs on the electric motorcycle, the limit switch will be triggered, causing the equipment to stop immediately and issue an alarm. 

Add emergency exhaust smoke, smoke detectors and solenoid valves at the front end of the sprinkler pipes on the top of the equipment. The solenoid valves should be linked with the internal smoke detectors.
