How Is Battery Capacity Measured? The battery capacity test measures how much capacity (current x time) in ampere-hours, Ah, the battery can deliver before the terminal voltage is reached. The measurement assumes the current flow shall be maintained at a constant rate. For a lead-acid battery, the test time is approximated to be near the ...
Also known as load testing, or discharge testing, capacity testing is a dynamic test whereby a simulated load (in amperes or watts) is imposed on the battery system for a specified time. The discharge continues to a defined end-of-discharge (EOD) voltage, referencing a measured battery temperature taken at the start of the test.
Scope of application: The battery capacity test and grading system is one of the necessary equipment for lithium-ion battery manufacturing. For lithium-ion battery cell manufacturers, it is a battery production and testing machine for the formation and grading of battery cells.
Step-7: End the capacity test when the battery reaches the predetermined end point voltage (1.8V), a cell (or) unit reverses, or a safety issue is identified. The ampere-hour rating is calculated by multiplying the number of amperes of current that the battery can supply by the number of hours it takes to reach a specific end point voltage.
Capacity testing is part of a successful and complete maintenance program, so it stands to reason that testing practices are covered in these documents. Of course, the battery’s manufacturer can be consulted about testing processes and regimes; most support the IEEE recommended practices, guides and standards.
The capacity corrected to 25°C is 88.7% and the battery passed the test. Failure to use K t results in a capacity calculation of 96.7%, an error of 8%. The only way to know the capacity of a battery is to perform a capacity test under specific test conditions. Tests should be conducted periodically based on the applicable IEEE recommended practice.
The Institute of Electrical and Electronics Engineers (IEEE) recommended practices relating to capacity testing of lead-acid and nickel-cadmium batteries are the same documents that provide information relating to maintenance.
