Battery self-test report

How to test a single cell battery?

Venting mechanism exists on the narrow side of pouch cell. Single cell battery. Test is carried out at 20°C±5°C. Charging method declared by the manufacturer. Prior to charging, the battery shall have been discharged at 20 °C ± 5 °C at a constant current of 0,2 It A down to a specified final voltage.

For how long should a battery be kept on test?

The battery pack should remain on test for an additional one hour if the short circuit current shows a rapid decline. This typically refers to a condition where the per cell voltage (series cells only) of the battery is below 0,8 V and is decreasing by less than 0,1 V in a 30-minute period. In such a case, the battery should be kept on test for a total duration of one hour and thirty minutes.

How do you test a fully charged battery?

Fully charged batteries were subjected to a short circuit test at 20°C ± 5°C. The external resistance of 80±20 mΩ. The cells were tested for 24 h or until the case temperature declined by 20% of the maximum temperature rise.

What happens after a battery test?

After the test (Charging temp. Upper limit 45°C): Fire: the emission of flames from a cell or battery. Explosion: failure that occurs when a cell container or battery case opens violently and major components are forcibly expelled. Fire: the emission of flames from a cell or battery.

What are the requirements for a battery test?

Cells and batteries meet this requirement if there is no leakage, no venting, no disassembly, no rupture and no fire and if the open circuit voltage of each test cell or battery after testing is not less than 90% of its voltage immediately prior to this procedure.

What is a battery life estimate?

"Battery life estimates" is probably the most interesting section for most users since you can see what the operating system predicts for the battery life with regular usage. This feedback is usually more stable and accurate than the live estimate found by clicking the battery icon.
