What properties are generally measured for industrial lithium batteries? What equipment is needed?
Industrial lithium batteries have a wide range of applications, and more and more products use lithium batteries. But what aspects of performance need to be tested as a lithium battery? What testing equipment is needed at the same time?
The main testing aspects of industrial lithium batteries are:
1. Check whether the appearance of the battery is clean, whether there is rust, whether the coding is clear, and whether the casing is intact;
2. Check whether the voltage, internal resistance, capacity, and discharge platform of the lithium battery are consistent;
3. Capacity test, cycle test, high and low temperature cycle, rate cycle, see the degree of curve overlap;
4. Test rate charge and discharge, test temperature rise, test dynamic pressure difference;
5. Store the batch at high temperature and normal temperature, and observe the static pressure difference;
6. Safety tests such as short circuit, puncture, impact, thermal shock, high and low temperature charge and discharge, etc.;
7. Anatomical analysis of the neatness of the winding core, pole piece length, number of pole ears, welding, thickness of auxiliary materials, etc.;
For various testing, different testing instruments are needed:
1. Visual inspection: according to product technical specifications and quality requirements, visual inspection;
2. Voltage and internal resistance detection: high-precision multimeter, internal resistance tester, battery sorter, comprehensive tester, etc.
3. Capacity and discharge platform curve: battery sub-capacity cabinet, aging tester, discharge tester;
4. Cycle test, rate test, and rise test: battery discharge test instrument, battery aging cabinet;
5. High and low temperature test: high and low temperature test instrument;
6. Safety tests such as short circuit, puncture, impact, thermal shock, high and low temperature charge and discharge: professional safety test equipment;
If you want to check whether the lithium battery is good or bad, it is a complicated system project, which requires professional technicians to cooperate with professional equipment. It is recommended to find a regular lithium battery manufacturer to cooperate.
The above is the Benwei lithium battery sorted out for everyone, for reference only.
