本充電電源為三階段自動(dòng)充電電源（恒流均衡充電-恒壓均衡充 電-浮充電）如下圖所示。對(duì)電瓶充電的全過(guò)程是先進(jìn)入均衡 充電，自動(dòng)完成先恒流，后恒壓，待電流降到接近零時(shí)均衡充 電完成，令其（手動(dòng)或自動(dòng)）轉(zhuǎn)入“浮充”，以涓流維持電瓶在 滿充狀態(tài)。其充電詳細(xì)過(guò)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:

以24V鉛酸蓄電池為例，過(guò)程是：接好電池，開啟后，充電電源軟啟動(dòng)，電壓從21.6V(電池放電下限值)開始上升，充電電流逐步增大到額定恒流值，充電電源進(jìn)入恒流充電過(guò)程，此后充電電壓逐漸升至28.2V（均充電壓值），此恒流充電過(guò)程一般情況下約需1～2小時(shí)
