inished product tester

Specification:

1.The equipment is suitable for filling and discharging the same mouth

2.equipment and computer communication using photoelectric isolation

3.self checking function,software programmable control,friendly human-machine interaction interface

4.battery overcurrent test,short circuit test and split capacity test,can save test data

5.battery internal resistance test,load carrying capacity test,monomer consistency evalution

fast and accurate device for testing the performance of finished

batteries. The main test items are: no-load voltage, AC internal resistance,

AC internal resistance, charging current, charging voltage, discharging current,

load voltage, over current protection current, and over current recovery voltage.

Test of short circuit protection time. The system uses a 32-bit ARM processor,

and the voltage and current use 16-bit AD converters. Compared with similar

devices, the test speed is faster, the test accuracy is higher, and multiple

devices can be operated simultaneously. Widely used in automotive electronics,aerospace, marine, solar energy storage, electric bicycles, electric

motorcycles, backup power batteries, communication power and other power battery

pack production and scientific research experimental testing.

Test items

1. No-load voltage: test the voltage between the positive and negative terminals

of the open circuit of the battery.

2. AC internal resistance: test the resistance of the battery’s open and negative

terminals.

3. DC internal resistance: test the resistance value at both ends of the battery

discharge circuit

4. Discharge test: test the continuous load capacity of the battery, and let

the battery continue to discharge for a certain period of time to check the

voltage drop.

5. Discharge overcurrent test: test the battery’s high current discharge

protection function. The battery’s high current discharge triggers the battery

protection board’s discharge over current protection function.

6. Short-circuit protection: test the positive and negative battery

short-circuit protection time (microsecond level).

7. Charging test: test the battery continuous charging function, and test whether

the battery charging function is good.

8. Charging overcurrent test: test the battery high-current charging protection

function. The battery high-current charging triggers the battery protection

board charging current protection function.
