Charge/discharge cycle testing is one evaluation test method used to meet this demand. The test objective is to determine the number of times a battery can be used by evaluating it until it deteriorates after repeated cycles of charging and discharging.
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.
The test objective is to determine the number of times a battery can be used by evaluating it until it deteriorates after repeated cycles of charging and discharging. The standard method is to charge and discharge repeatedly at the recommended charge and discharge rates.
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.
For an identical current, a discharge time shorter than the charge time indicates low coulombic efficiency. At the end of the battery life, there is a decrease in battery charging and discharging times. Likewise, sudden variations in potential can be observed in the event of the appearance of micro-short circuits or component failures.
The Charging Cycles of Lithium-ion Polymer Batteries
If you do not use lithium batteries often, please remember to complete a charging cycle every month and do a power calibration, i.e. deep discharge and deep charge, once. After the nominal number of charge and discharge cycles is used up, a battery''s ability to store power will drop to a certain level, but the battery can continue to be used ...
