Battery discharge testing, also known as battery load testing, is a process that test battery health statement by constant current discharging of the set value by continuously the discharge current from a fully charged state and then measuring how long the battery lasts.
Notable discharge testing methods include load bank testing, capacity testing, partial discharge, and charge/discharge cycle testing. The first one is load bank testing. It is the most comprehensive test by which someone can evaluate battery truly. It verifies that the battery can supply its specified power when it is required.
There are several methods: constant current discharge, constant power discharge, constant resistance discharge that can be used to perform a capacity test, but the most common method involves discharging the battery at a constant current until the voltage drops to a predetermined level.
The charging conditions of the battery: charging rate, temperature, cut-off voltage affect the capacity of the battery, thus determining the discharge capacity. Method of determination of battery capacity: Different industries have different test standards according to the working conditions.
The constant current discharge method is a more accurate battery capacity test method. Connect the battery to a certain load and discharge it at a constant current until the battery voltage drops to the predetermined cut-off voltage. By measuring the discharge time and combining the current value, the battery capacity can be accurately calculated.
Load bank capability of delivering the required discharge current. Use digital voltmeters to check entire battery discharge voltage. Use an amp meter to check battery discharge current. Use a digital voltmeter to check individual cell/unit voltages undergoing discharge. Use a stopwatch to check discharge time.
