2V 蓄电池,串联可产生 4V 电压

命名方式

串联的电池个数 + 蓄电池型号 + 容量

比如“3GFM100”,指3个串联电池,100Ah。

1Ah = 1000 mAh。mAh = 毫安

作用

  • 平衡滤波: 对高次谐波电流有极大的阻抗,对低次谐波电流有极小的阻抗。

  • 荷(存)电备用

  • -48V 直流供电

VRLA, valve-regulated lead-acid battery: 阀控式密封铅酸蓄电池

容量

额定容量(C10C_{10}C10​): 在25摄氏度,连续10个小时能被放出来的电。

I10=C1010=放电电流=容量放电率I3=2.5⋅I10I1=5.5⋅I10C3=0.75⋅C10C1=0.55⋅C10\begin{align*} I_{10} = \frac{C_{10}}{10} = 放电电流 = \frac{容量}{放电率} \\ I_3 = 2.5 \cdot I_{10} \\ I_1 = 5.5 \cdot I_{10} \\ \\ C_3 = 0.75 \cdot C_{10} \\ C_1 = 0.55 \cdot C_{10} \end{align*}I10​=10C10​​=放电电流=放电率容量​I3​=2.5⋅I10​I1​=5.5⋅I10​C3​=0.75⋅C10​C1​=0.55⋅C10​​

c = capacity = 容量

i = 放电电流

实际容量: 在25摄氏度,一直放电直到只剩1.8V,能被放出来的电

影响因数: (几小时)放电率、温度、电解液浓度、终止电压、电池新旧

电压

浮冲电压(充满后继续充): 2.23V - 2.27V

每上升1度,电压减小3~4mV

均充电压: 2.30V - 2.35V

为了防止单节电池间的电压不平衡

使用这种充电方式的条件:

  • 使用浮冲电压法充电时,测得>=两节电池的电压都低于2.18V

  • 全浮冲长达6个月之后

  • 放电超过额定容量的20%

  • 长时间搁置不用

关于 终止电压

小电流放电,终止电压高

大电流放电,终止电压低

终止电压指的是: 放电到什么程度,不能让电池继续放电(否则会损坏电池)。比如1.8V。

关于 极柱电压

打开盖子,两个相邻电池正负极间的电压,越小越好。(因为真正工作时,他们两个之间相连,相当于导线相连,自然是电压越小越好)
