如何串联和并联JLG电池连接

历史学家认为，本杰明·富兰克林 (Benjamin Franklin) 于 1749 年将成对的电池命名为“电池”。当时美国正在经历一段冲突时期，它们让他想起了准备与敌人交战的大炮。串联和并联电池连接使我们能够操纵电压和容量，从而提高其效率。我们可以说它们是他们成功的关键。

串联或并联连接电池

能源本身的潜力受到严格限制。富兰克林应该知道一匹马和两匹马的越野车之间的区别。众所周知，一对会走得更快，或者走得更远。串联和并联电池连接实现了类似的功能。

串联电池

Batteries in series have their opposite terminals connected together as we illustrate in our first image. This creates a simple circuit where their combined voltage increases, but their endurance remains the same.

So, if for example we joined two fully-charged 6-volt lead batteries in series, then they should produce 12-volts. However, they would go flat in the same time as a single one would.

Batteries in Parallel

Batteries in parallel have their like-to-like terminals connected together, as we illustrate in our second image. The net result is the endurance (capacity) multiplies, while their voltage stays the same.

So if for example we joined two fully-charged 6-volt lead batteries in parallel, we should still get 6-volts. Although the pair should last twice as long as a single one.

Different Combinations of Sets of Batteries

It quite often happens we need to increase both battery capacity, and voltage at the same time. A combination of series and parallel battery connections helps us achieve this goal. However, we should only use matching batteries of identical ratings, and in the same state of charge.
