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.
In battery pack charge/discharge testing, technicians test for anomalous voltage or temperature readings at each cell and evaluate the batteries’ characteristics.
Engineers also check for any malfunction, temperature rise in the battery pack, current carrying capacity, cooling capacity, and overall mechanical structure. After complete testing, packs may undergo extra testing to simulate the typical conditions and be integrated into the system or end-product.
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.
Although many tests can be performed to assess the condition of the batteries such as ohmic testing, specific gravity, state of charge etc., only the capacity test, commonly referred to as the discharge or load test, can measure the true capacity of the battery system and in turn determine the state of heath of the batteries.
Additionally, other tests like thermal abuse, mechanical vibration, high-voltage protection, and environmental tests are carried out at this level to ensure voltages are accurate and safe, temperature sensors function effectively, and cells are well balanced. Pack level testing is sometimes also called End-of-Line Testing or Assembly Testing.
