EV Mobility Industry

During the EV battery pack manufacturing process, it is important to verify the battery discharging capacity, and the battery discharge testing equipment is used for this purpose. However, the equipment itself needs to be calibrated regularly before the test starts. 

The traditional method to calibrate the equipment is with current shunt. But the operation is difficult, temperature drift is an issue and it is also not intelligent. 

However, nowadays, the battery OEMs start to use Hangzhi HIU AC / DC high precision current tester to replace the current shunts, due its advantages: 

1. Higher Accuracy than current shunts
The HIU1000B High—Precision AC / DC high precision current Tester launched by Hangzhi, with a precision of 0.02% level, which can meet the measurement calibration of all charge—discharge testing equipment
2. Simpler to use
Simply pass the test cable through the round hole of the instrument
3. No human operation error
There is no requirement for the position of the test cable in the round hole, and the test cable position does not affect the test accuracy
4.Can be used for long time
Temperature drift ippm, no impact on the test accuracy

5. Lower cost
For example the cost of HIU1500 is much lower than current shunt 1500A with 0.02% accuracy.
