The internal voltage test of lithium battery is: (UL standard) The simulated battery is at an altitude of 15240m above sea level (low pressure 11.6kPa) to check whether the battery leaks or bulges.
Other important tests include safety testing (to make sure the battery won’t overheat or catch fire) and cycle life testing (to see how many times the battery can be discharged/charged without degrading). Both of these tests are essential in ensuring that lithium-ion batteries are safe and reliable.
The performance tests of lithium batteries include voltage, internal resistance, capacity, internal voltage, self-discharge rate, cycle life, sealing performance, safety performance, storage performance, appearance, etc. Performance test is up to 230 items. As well as overcharge, over discharge, weld-ability, corrosion resistance, etc.
Capacity tests are typically done with a discharge rate of 0.1C (100mA), which is about the same as a cell phone’s standby current draw. The other common test for lithium batteries is called an impedance test. This measures the internal resistance of the battery, which increases as the battery ages and wears out.
When testing a lithium-ion battery with a multimeter, the voltage test is one of the most important tests to perform. This test will help you determine the voltage level of the battery, which can indicate whether the battery is fully charged or not. Here are the steps to conduct the voltage test:
Here are some common types of load tests: Constant Current Load Test: This test applies a constant current load to the battery and measures its voltage response over time. It helps assess the battery’s capacity and performance under sustained current draw. Pulse Load Test: This test subjects the battery to intermittent high-current pulses.
