Title: Charging of lead storage battery
Inventor: SATOU TAKUMI
IPC: H02J7/04
Filed: 1982-10-27
Abstract: PURPOSE:To remove difference in specific gravity between the upper and the lower parts of electrolyte by performing forced current feeding for a given time, when a storage battery is charged by 80-105%, with a current within a specified range of battery capacity by increasing charging voltage. CONSTITUTION:In the charging process of a lead storage battery, when it is charged by 80-105%, forced current feeding is performed for 5-30min with a current of 0.1-0.2C [A] when the capacity of the battery is supposed to be [C] by increasing charging voltage. As a result, difference in specific gravity between the upper and the lower parts of electrolyte is remarkably improved by stirring the electrolyte effectively. Consequently, any early deterioration of part of an active material exposed to electrolyte of a high specific gravity can be prevented. Besides, the charging time and the quantity of charging electricity can be saved.
