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.
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.
Discharge rate refers to the rate at which a battery is depleted of its stored electrical energy. It is usually measured in terms of amps or milliamps per hour (Ah or mAh), and it represents the current drawn from the battery over a certain period of time.
It is mainly used in manufacturing during production of the battery. Battery test equipment can also be used in R&D departments to study battery performance. One typical application of a BTS is to charge and discharge a one-cell lithium-ion battery. Considering the voltage drop in the cable, the voltage required to do this is 0V to 5V.
Charging and discharging modes of the battery are provided by appropriate position of switches S1-S4 and by a controlled voltage stabilizer (CVS). ... ... Errors of the ADC and reference voltage are minimized by selecting appropriate electronic components.
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.
