There is significantly less time available to test during production due to high throughput. Typically the system validation done on the pack level can easily take upwards of 6 minutes per unit. For example, an EV battery manufacturer may plan to manufacture up to 40,000 or more battery packs a year.
An inherent part of battery testing includes charge and discharge tests to measure the battery capacity and the DC internal resistance at different state of charges (SoC). A battery is charged by using a source to put energy into the battery or discharged by using a load to draw energy out. Let's consider a one-time-use battery as an example.
To test the capacity of a battery cell, you have to fully charge and fully discharge the cell while precisely measuring the energy in at least one direction. Also, being able to test a battery's true capacity gives you leverage when buying battery cells.
The good news is that you can get a 18650 or 21700 cell charger/tester that charges the cells and tests the capacity. To check the IR of an individual cell you will need a standalone 4-wire IR tester, we recommend the one below. Testing a battery's capacity is an important part of knowing the overall health of a battery.
