A C-rate is a measure of the rate at which a battery is discharged relative to its maximum capacity. A 1C rate means that the discharge current will discharge the entire battery in 1 hour. For a battery with a capacity of 100 Amp-hrs, this equates to a discharge current of 100 Amps. A 5C rate for this battery would be 500 Amps, and a C/2 rate would

What is charge/discharge cycle testing?
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.
What is accelerated cycle life testing of lithium-ion batteries?
If you have questions or are interested to contribute your data to the battery data collective, please contact Prof. Michael Pecht. Accelerated cycle life testing of lithium-ion batteries is conducted as a means to assess whether a battery will meet its life cycle requirements.
What is a cycle life test for a car battery?
For vehicle batteries, IEC 62660-1 calls for cycle life testing with the charge/discharge rates rapidly varied. A combination of charge/discharge profiles is used. Some profiles have a slightly larger charge quantity than discharge quantity, and others have a slightly larger discharge quantity than charge quantity.
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.
How are battery currents measured?
A number of battery currents have been acquired from actual vehicles and applications, and these can be scaled to the capacity of the cell / module / battery under test. As can be seen in the figures, the actual battery current and voltage can then be recorded on test, either as single cycles, or on continuous runs to perform endurance testing.
How are cells / batteries tested?
Cells / batteries are housed in thermally controlled chambers whilst the tests run to characterise the devices under known conditions. Information on state of charge (SoC), internal impedance and battery health can be obtained from the devices under test.
