Description

Features

The comprehensive test equipment for finished battery is a fast and accurate device for testing the performance of finished battery. The main test items include: open circuit voltage, AC internal resistance, discharge test, discharge over-current test, short circuit protection test, charging test and charging protection test. The system adopts 32-bit ARM processor and 16 bit AD converter for voltage and current. Compared with similar equipment, it has faster test speed, higher test accuracy and supports simultaneous operation of multiple equipment. It is widely used in the production, scientific research and experimental test of power batteries such as automotive electronics, aerospace, ships, solar energy storage, electric bicycles, electric motorcycles, backup power batteries, communication power supplies, etc.

Test items

1. Open circuit voltage: test the voltage at both ends of the positive and negative poles of the battery.

2. AC internal resistance: test the resistance at both ends of the battery discharge circuit.

3. Discharge test: test the continuous carrying capacity of the battery, and check the voltage drop of the battery for a certain period of continuous discharge.

4. Discharge over-current test: test the high current discharge protection function of the battery, and the high current discharge of the battery triggers the discharge over-current protection function of the battery protection board.

5. Short circuit protection: test the battery positive and negative short circuit battery cut-off protection time (microsecond level).

6. Charging test: test the battery's continuous charging function and whether the battery's charging function is good.

7. Charging over-current test: test the high current charging protection function of the battery, and the high current charging of the battery triggers the charging current protection function of the battery protection board.
