本充电电源为三阶段自动充电电源（恒流均衡充电-恒压均衡充 电-浮充电）如下图所示。对电瓶充电的全过程是先进入均衡 充电，自动完成先恒流，后恒压，待电流降到接近零时均衡充 电完成，令其（手动或自动）转入“浮充”，以涓流维持电瓶在 满充状态。其充电详细过程如下：

Three stages of the automatic charging power supply are constant-current equalizing charge, constant-voltage equalizing charge and floating charge as shown in the following figure. The whole process of battery charge is to enter the mode of equalizing charge first and automatically finishes the constant-current and then constant-voltage charge. The equalizing charge is finished when the current is near zero, and the mode should be transferred into “Floating charge” (manually or automatically). The trickle maintains the status of full charge. The detailed process of charge is as follows:
