This is achieved by running a load and measuring its current while observing voltage drop. Resistance Testing: This testing method involves the use of an ohmmeter, a type of multimeter, to measure the electrical resistance within the battery. A battery's resistance should ideally be very low, close to zero, between 20 and 50 mOhms.
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.
Unfortunately, the most accurate way to determine if a battery has gone bad and overall battery health would be to use all three tests: Voltage, Load, and Resistance. Voltage Testing: This method entails using a device called a multimeter that measures the electrical potential difference, or voltage, between the battery's two terminals.
IEC stipulates that the standard cycle life test of lithium batteries is: Step 1: Discharge the cell to 3.0V with the discharge rate at 0.2C and then charge to 4.2V with charging rate at 1C and constant current and constant voltage. The experiment requires that the cut-off current is 20mA. Want More Details: Download our battery design ebook.
30A×0.2Ω=6V. So, a 48V battery would drop to 42 volts. With a 100mOhm resistance and the same 30 amp load, the voltage drop is 30A×0.1Ω=3V 30A×0.1Ω=3V. This would result in a drop to 45 volts for a 48V battery.
If you’re wondering how to test the capacity of your Lifepo4 battery, there are a few different ways you can do it. One way is to use a multimeter to measure the voltage of the battery. Another way is to use a capacity tester, which will give you a more accurate reading of the battery’s capacity.
