Typical application
Verifying the battery discharging capacity is crucial during the manufacturing of electric vehicle (EV) battery packs. Battery discharge testing apparatus is employed to accomplish this. Nevertheless, the apparatus must be calibrated on a regular basis prior to the commencement of the test.
The equipment is calibrated using a current switch, which is the conventional method. However, the operation is challenging, temperature drift is a concern, and it is not intelligent.
Nevertheless, in the present day, battery OEMs are increasingly utilising the Hangzhi HIU AC/DC high precision current tester to replace current shunts, as it offers the following benefits:
1. Greater precision than existing shunts
The HIU1000B High-Precision AC/DC high current meter, which was recently introduced by Hangzhi, has a precision of 0.02% and is capable of meeting the measurement calibration requirements of all charge-discharge testing instruments.
2. Easier to operate
Pass the test cable through the instrument's round opening.
3. Absence of human error
The test cable's position in the round cavity is not mandatory, and it does not influence the test's accuracy.
4. Has the potential to be utilised for an extended period of time
The measurement accuracy is not affected by temperature drift in ippm.
5. Reduced expense
For instance, the HIU1500 is significantly less expensive than the current 1500A shunt, which has an accuracy of 0.02%.
