铅酸蓄电池如何充电？

铅酸电池最担心的 是在深度放电后立即充电。 在这种情况下，电池寿命会大大降低。不要多次深放电。所谓深度放电，是指电动汽车欠电压。切断电源后，绝对不能继续通电行驶。电动车电池的间歇性放电对电池伤害最大。铅酸蓄电池充电方法如下：

1. 当电池指示灯显示剩余电量的三分之一时充电。

2. The charging environment should be kept dry and tidy, and the charger should not be wrapped in plastic bags or plastic bottles, because it is very easy to burn when the charger cannot breathe.

3. Try not to use fast charging, if not necessary, do not use it more than twice within a month.

4. The charger is placed in a fixed place, do not bump it, even if it is carried, it must fully consider the bumps that cause failures.

5. Use the standard charger to charge.

Definition: The electrodes are mainly made of lead and its oxides, and the electrolyte is a battery of sulfuric acid solution. In the discharge state, 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 is lead sulfate. Divided into vented batteries and maintenance-free lead-acid batteries. The battery is mainly composed of a tubular positive plate, a negative plate, an electrolyte, a separator, a battery tank, a battery cover, a pole, and a liquid injection cover. The electrodes of the vented battery are composed of lead and lead oxides, and the electrolyte is an aqueous solution of sulfuric acid. The main advantage is voltage stability. With the development of technology, lead-acid batteries have a 更长的使用寿命和更容易的维护。进行放电时，硫酸溶液的浓度会不断降低。当溶液密度降至1.18g/ml时，应停止充电。

充电：  2PbSO ₄ + 2H 2 O= PbO 2 +Pb+2H 2 SO ₄（电解槽） 

放电：  PbO2 + Pb + 2H2SO4 = 2PbSO4 + 2H2O （原电池）  

阳极：  PbSO ₄ +2H 2 O - 2e-= PbO 2 +4H + +SO ₄² -  

阴极：  PbSO ₄ +2e-= Pb+S0 ₄² - 

负极：  Pb+SO ₄² - - 2e= PbSO ₄ 

正：  PbO 2 +4H+ +SO ₄² -+2e-= PbSO ₄ +2H 2 O
