Abstract

The object of the present invention is to provide a two-day charging process for reducing charging energy consumption of a 20Ah storage battery. By setting a charging and discharging process of twenty-seven steps, the voltage in the charging process is controlled through the current stage, and at the same time, the conversion of a small current is used to improve the battery life. Charging efficiency, thereby reducing the battery charging rate from 9.92 times to 8.62 times, reducing charging energy consumption by 437wh / pc, reducing energy consumption, saving costs, and suitable for production.

Description

technical field [0001] The invention relates to the field of storage battery manufacturing, in particular to a two-day charging process for reducing charging energy consumption of a 20Ah storage battery. Background technique [0002] The storage battery needs to be charged and formed during the manufacturing process. The formation power is one of the main factors affecting the battery formation. The formation power is too low, the active material cannot be fully converted, and the lead dioxide content is low, resulting in poor initial performance of the battery. However, due to the high formation power, in addition to increased energy loss, the temperature rise during the formation process is not easy to control, and the impact of the gas on the plate is also large, which will affect the battery life. Therefore, an appropriate amount of formation power should be selected. The charging energy consumption of the current 20Ah storage battery is relatively high, and the chargi...
