Car battery charger Connections

High Quality Car Battery Charger Connections Promotion-Shop for

There are many ways to connect a group of batteries in both series and parallel at the same time. This is common practice in many battery power appliances, particularly in electric vehicles and large UPS systems where the battery packs require large voltages and amp-hour capacities. It is not uncommon to have battery packs with several hundred volts and several hundred amp-hours.

Just to get an idea of how these connections can be made, we'll look at two examples, with 4 batteries each, using 12 volt, 20 Ah batteries. In each of the examples, the 4 batteries are identified as A, B, C, and D. Example 1, shown in Figure 4, has 2 pairs of series connected batteries joined in a single parallel connection. In this type of arrangement, we refer to each pair of series connected batteries as a "string". Batteries A and C are in series. Batteries B and D are in series. The string A and C is in parallel with the string B and D. Notice that the total battery pack voltage is 24 volts and that the total battery pack capacity is 40 amp-hours.

Example 2, shown in Figure 5, has 2 pairs of parallel-connected batteries joined in a single series connection. Batteries A and B are in parallel. Batteries C and D are in parallel. The parallel combination A and B is in series with the parallel combination C and D. Again, the total battery pack voltage is 24 volts and that the total battery pack capacity is 40 amp-hours.
