Battery charge and discharge test system quality

What is a battery discharge test?

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.

What is a battery charge / discharge cycle test system?

High precision, integrated battery charge / discharge cycle test systems designed for lithium ion and other chemistries. Advanced features include regenerative discharge systems that recycles energy from the battery back into the channels in the system or to the grid.

What is a battery test?

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.

Does discharge current affect battery capacity test?

Thus, the discharge current during capacity test may affect the test for last capacity. Though every battery has labeled the manufacture speciation and uses 0.2C or 0.3C for capacity test commonly, the dynamic battery often performs charge and discharge higher than 0.2C or 0.3C.

What is a battery capacity test?

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.

Can a battery pause be counted in a discharge test?

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.
