The use of rechargeable batteries in testing systems is becoming increasingly extensive. In order to initialize the rechargeable batteries, the multiple charging and discharging cycles are demanded. In this process, the current and voltage of the battery must be controlled accurately. It is usually required that the precision can reach 0.1%.
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.
Among 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.
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.
There are a number of different tests like: visual inspections, specific gravity, float voltage and current measurements, discharge test, individual cell condition, inter-cell resistance, and others, which are recommended in IEEE, NERC and other standards for diagnosing the condition of the battery banks.
There are two modes of battery charging and discharging: constant current mode and constant voltage mode. In a typical battery charging system, the batteries are charged or discharged at a constant current until the preset voltage is reached. After reaching the preset voltage, the system switches to the constant voltage mode.
