Customer ServiceAmong all the tests, the discharge test (also known as load test or capacity test) is the only test that can accurately measure the true capacity of a battery system and in turn determine the state of health of batteries.
Because this determines the ability of the battery system to stabilize the output power, which in turn affects the vehicle performance of the EV. The following table is the main test steps for the constant power discharge test of battery cells at different temperatures and different powers.
Only one pause is allowed for the duration of the test and the pause time should not be counted in the total discharge time2. Once the test is completed, determine the battery capacity. The test equipment can then be disconnected. While performing the discharge test, one should be prepared to bypass weak cells approaching polarity reversal.
For the performance test, a constant current method is generally used where a constant current specified by the manufacturer is applied for an accompanying specified time. Battery manufacturers publish tables that include different discharge rates specified for different periods of time.
In any case, no matter how big the load is, power is dissipated in the instrument as heat during the test. Care should be taken to direct the heat dissipation away from the batteries and/or properly ventilate the area to avoid heating the room or batteries while testing.
The discharge rate of a battery can be affected by a number of factors, including the load being placed on the battery, the age of the battery, and the temperature at which it is being used. A battery with a high discharge rate is able to deliver a large amount of electrical current in a short period of time.
