Definition and Explanation of Parallel Connections In a parallel connection, batteries are connected side by side, with their positive terminals connected together and their negative terminals connected together. This results in an increase in the total current, while the voltage across the batteries remains the same.
Series Connection: In a battery in series, cells are connected end-to-end, increasing the total voltage. Parallel Connection: In parallel batteries, all positive terminals are connected together, and all negative terminals are connected together, keeping the voltage the same but increasing the total current.
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.
Parallel connection attains higher capacity by adding up the total ampere-hour (Ah). Some packs may consist of a combination of series and parallel connections. Laptop batteries commonly have four 3.6V Li-ion cells in series to achieve a nominal voltage 14.4V and two in parallel to boost the capacity from 2,400mAh to 4,800mAh.
Consider the example of two batteries connected in parallel: Battery A has a voltage of 6 volts and a current of 2 amps, while Battery B has a voltage of 6 volts and a current of 3 amps. When connected in parallel, the total voltage remains at 6 volts, but the total current increases to 5 amps. Advantages and Disadvantages of Parallel Connections
The cells are connected in parallel to fulfill higher current capacity requirements if the device needs a higher current, but there is not enough space available for the battery. That device can use the parallel configuration to fit high-current capability in a small space.
Series vs Parallel: Understanding battery connections in one article
In most cases, a combination of both series and parallel configurations is used to create a powerful, stable battery pack with the necessary voltage and capacity. By understanding the principles behind series and parallel connections, you can design and assemble battery packs that are both safe and reliable.
