2V1000AH德国尼克NICK蓄电池NCG1000-2富液式照明系统
有固定电阻的恒定电压充电
为补救恒定电压充电的缺点而采用的一种方法。即在充电电源与电池之间串联一电阻，这样充电初期的电流可以调整。但有时大充电电流受到---，随充电过程的进行，蓄电池电压逐渐上升，电流却几乎成为直线衰减。有时使用两个电阻值，约在2.4v时，从低电阻转换到高电阻，以减少出气。
During the charging process, thecharging current remains constant, which is called constant currentcharging method, abbreviated as constant current charging method orequal current charging method. During the charging process, as thebattery voltage gradually increases, the charging current graduallydecreases. In order to maintain the charging current fromdecreasing due to the increase in battery terminal voltage, thepower supply voltage must be gradually increased during thecharging process to keep the charging current constant. Thisrequires a high degree of automation for the charging equipment,and generally simple charging equipment cannot meet therequirements of constant current charging.
