How to determine the test electric vehicle lithium-ion battery capacity? 1. Test the battery capacity to test the battery capacity to test the capacity of the battery capacity. It is difficult to check that the battery capacity is not loaded with the voltage stop of the voltage meter or the meter.

When the voltage is measured on a single measurement, the current is extremely small, so it does not have a large voltage drop in the battery inside, so the display voltage is not low, but if a considerable load, if the headlight (load current 10 ~ 15a), press The speaker (load current is 6 ~ 12A), the battery will make the lights, the hoarse, thus showing insufficient storage. 2. Test the battery capacity with a specific gravity.

It is also a common method. Generally, the standard specific gravity of the electrolytic solution is 1.25 ~ 1.

29kg / L at 20 ¡ã C; if the battery is less than the above value, the electrolyte ratio is less than the above value. More than 1.06kg / L, the battery is insufficient, to be charged; if the battery is more than 1.

06kg / L or less when the battery is 20 ¡ã C, indicating that the battery has been completely discharged or damaged. According to this principle, the specific gravity of the battery electrolyte can be used to measure the capacity of the battery, and the battery can be further determined. How to identify lithium-ion battery products for virtual standard capacity? The number of repeatable charges of the lithium-ion battery is also limited, generally 500 to 1000 times.

Therefore, maintenance is a key factor in the longness of lithium-ion battery life. Based on the characteristics of lithium ion batteries, we are attributed to the following points: You can be depth discharge, non-depth discharge. Because depth discharge pen affects the service life of lithium-ion batteries.

3, long-term (more than 3 months) Do not use lithium-ion batteries, charge to 50% of power storage.
