Lead-acid batteries are batteries whose electrodes are mainly made of lead and its oxides, and the electrolyte is a sulfuric acid solution. In the discharge state of a lead-acid battery, the main component of the positive electrode is lead dioxide and the main component of the negative electrode is lead; in the charged state, the main component of the positive and negative electrodes are lead sulfate.

　　What are the common charging methods for lead-acid batteries? ? How much do you know about this problem? ? Today, the editor of Zhengzhou Kanglida Electronic Power Supply Co., Ltd. will give you some information on this issue. I hope it will be helpful to you. In the future, you can avoid detours when using and purchasing.　

　　1, pulse charging

This is a simple and economical method. The low-voltage AC output from the transformer secondary is rectified into pulsating DC (not filtered) to charge the battery. This method has a large charging current and a fast charging speed. The disadvantage is that when the grid voltage fluctuates, the charging The current also fluctuates. It is easy to happen that the battery is damaged due to high charging current, rising battery temperature, and large electrolyte loss. Therefore, this method is rarely used in maintenance-free sealed lead-acid batteries.

　　2, charge with constant current

In order to prevent too high temperature rise in the battery and too much electrolyte loss, the charging current is adjusted to be relatively small, and the charging time is longer. On the other hand, if the charging time is too long, overcharging will occur, in order to prevent overcharging. If the battery is damaged, an overcharge detection or timing circuit is required.

　　3, constant voltage charging

　　 Both theory and practice have proved that constant voltage charging is safe when the charging voltage is lower than the upper limit of the charging voltage. Even if the charging time is long, it is not dangerous. If necessary, the battery can still work in a floating state.
