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.
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.
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.
Do not let lithium batteries with different voltages in series. Due to the problem of consistency of lithium batteries, they are grouped in series under the same system (such as ternary or lithium iron), and they also need to be selected with the same voltage, internal resistance, and capacity.
The 12V lithium battery series system requires stricter parameter matching and a higher specification protection system. When multiple 12V lithium batteries are connected in series, the total voltage increases rapidly, and the voltage resistance requirements for the protection board increase exponentially.
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.
