铅酸蓄电池充电特性

铅酸蓄电池充电电流大，电池端电压升高快，充电电流与电池端电压通常有如下关系式。

V=E+IR

式中  V——电池端电压，V；

      E­——电池电动势，V；

      R——充电电流，A；

      R——电池内阻，Ω

充电电流大，IR 项增大，所以电池端电压增大。

The lead sour storage battery refreshes electric current big, the battery carries electric voltage to heat up quickly and refresh electric current and battery to carry electric voltage usually like bottom relation type.

V=E+IR

The V-battery in type carries electric voltage, V;

E-battery electromotive force, V;

R-refresh electric current, A;

Zu inside the R-battery, Ω

Refreshing electric current is big, the IR item enlarges, so the battery carries electric voltage aggrandizement.
