In actual use, lithium batteries need to be combined in parallel and series to obtain a lithium battery pack with a higher voltage and capacity to meet the actual power supply needs of the equipment.
Lithium batteries can indeed be connected in parallel, and this method is commonly used to achieve higher capacity and extend the runtime of a battery system. By connecting two or more lithium batteries with the same voltage in parallel, the resulting battery pack retains the same nominal voltage but boasts a higher Ah capacity.
The series and parallel connection of lithium batteries is a key technology to increase voltage and capacity, but it also contains safety risks. This article will analyze in detail the principles, methods and precautions of series and parallel connection of lithium batteries to help you avoid potential risks and build a battery system correctly.
Specific principles must be followed when charging parallel lithium battery packs: Use a matching charger: The voltage must be suitable for the nominal voltage of the individual batteries. The current setting is reasonable: usually 0.2-0.5C of the total capacity after parallel connection.
Balancing lithium batteries in parallel involves measuring each battery's voltage before connection, ensuring they're within an acceptable range of each other, and then connecting all positive and negative terminals together. What Does It Mean For Lithium Batteries To Be Balanced?
The key differences between battery packs in series and parallel involve voltage and capacity configurations. Series battery packs increase voltage while maintaining the same capacity. In contrast, parallel battery packs increase capacity while maintaining the same voltage.
Lithium batteries are connected in series when the goal is to increase the nominal voltage rating of one individual lithium battery - by connecting it in series strings with at least one more of the same type and specification - to meet the nominal operating voltage of the system the batteries are being installed to support.
