Title: Control method for charging lead storage battery
Inventor: KOMATSU TAKASHI
IPC: H02J7/04
Filed: 1986-01-17
Abstract: PURPOSE:To prevent the occurrence of adverse effects of under-charging and over-charging by providing multi-stage control which charges battery with a current of sufficient intensity at the beginning of charging and decreases the current when the voltage reaches a preset level. CONSTITUTION:A battery is charged with an appropriate current until a time t1 while increasing the voltage in accordance to an amount the charged electricity as the charging progresses. If the voltage reaches a preset level V1 at the time t1, current is decreased. This current of decreased level is supplied to fill the shortage of charge caused by insufficient period till time t1 for charging the battery fully. While the voltage decreases as the current decreases, but it increases again as the current continues to flow, even if it is of low intensity. When the voltage reaches the second preset level v2 at a time t2, the current is further lowered, sometimes to zero. By regulating this final current within a range where over-charging never causes effect, even if charging is continued for a long period, deterioration of the battery due to over-charging can be prevented.
