The lead-acid battery cycle life refers to the number of repeating charge discharges that the battery can undergo. The life and capacity of the lead-acid battery is relatively correlated, and the circulating life is closely related to the charge and discharge conditions. The larger the charging current (the faster charging speed), the shorter the life of the cycle. The life is an indicator indicating the battery capacity attenuation speed. As the use is in-depth, the attenuation of the battery capacity is inevitable, and when the capacity is attenuated to a certain value, the end is determined.
According to the newly developed electric bicycle battery standard, a certain capacity of 70% charge and discharge cycle will represent the life of the battery, and the pass line is 350 times. Therefore, for users who are less than 30 ㎞, if the motor, controller, charger, etc. is good, the method of use is correct, and the shortest service time of a set of batteries should be guaranteed for more than a year. of. Capacity and life are the main indicators of measuring battery performance, and capacity is generally in units of AH, indicating the capacity of battery reserve energy.
For example, a battery having a nominal capacity of 12ah must reach a level of 6a discharge, and placed to the termination voltage 3105V (36V) should not be less than 2 h. This battery is used for electric bicycles, with a load of 75kg, riding on a flat pavement, the working current is about 4A, the discharge time should be greater than 3h, the speed is 20 ㎞, then its theoretical continuation mileage will reach 50 ㎞. If you consider the brakes, start-up factors, the renewal mileage of the electric bicycle using this battery can reach 40 ~ 50. In general, the larger the discharge current, the shorter the life of the battery; the deeper the discharge depth, the shorter the life of the battery.
The lead-acid battery can cope with a short-time large current discharge, and the depth of discharge is not deep. When the small current is discharged, even if the discharge depth is slightly deep, the life of the battery is not large. The battery is most afraid of a continuous high current depth discharge. Factors affecting the life of lead-acid battery have a polar panel, such as composition, crystalline form, porosity, plate size, grid material, and structures, etc., also depend on a series of external factors, such as discharge current density , Electrolyte concentration and temperature, discharge depth, maintenance conditions, and storage time.
