奥斯达蓄电池对充电电压的的要求

奥斯达蓄电池充电电压高低对容量没有多大影响

我们通常认为电池在充电过程中电压的高低对电池容量互相关联，电压高则充入电量大，电压底则相对充入电量少。那么到底是不是这样呢？下面是一个实验得出的数据分析：

用一个水槽盛满水，电池放在水中，在电池上方有一个收集气体用的倒扣的漏斗，漏斗顶端装有可以计量气体容量的注射针筒。充电用可调稳压电源，用两只四位半数字万用表测量充电电流和充电电压。

试验时间是在冬季，水温5℃。实验条件是统一用2A电流充电，最充电电压分别用43V、44V、45V轮循环依次进行，浮充转换电流一律400mA，记录下每次的充电时间，包括充电末期随时间电流下降各点数据、开始析气电压，按时间记录析气量。电池充完后，用万分之几精度的电量台记录放电容量。充入电量是在计算纸上读出时间电流曲线与坐标之间的面积（电容量就是充电电流对时间的定积分）。

digit multimeters are used to measure the charging current and voltage.

Test time is in the winter, the water temperature is 5 ℃.The experimental condition was that 2A current was uniformly used for charging, and the maximum charging voltage was respectively used for 43V, 44V and 45V wheel cycle. The floating charging conversion current was uniformly 400mA, and the charging time of each time was recorded, including the data of each point at the end of charging with time current and the starting gas evolution voltage, and the gas evolution quantity was recorded according to the time.After the battery is charged, the discharge capacity is recorded with a power station with a precision of a few parts per million.Charging is the calculation of the area between the time current curve read on the paper and the coordinates (capacitance is the definite integral of the charging current against time).
