6 Frequently Asked Questions about “2 groups of lithium battery packs are used in series”
Are series and parallel connection of lithium batteries safe?
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.
Why is a lithium battery a series-parallel combination?
Due to the limited voltage and capacity of the single battery, in actual use, a series-parallel combination is required to obtain a higher voltage and ability to meet the existing power supply requirements of the equipment. Lithium batteries in series: the voltage is added, the capacity remains unchanged, and the internal resistance increases.
Why are lithium batteries connected in series?
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.
How to charge parallel lithium battery packs?
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.
What is the difference between series and parallel battery packs?
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.
What is a 12V lithium battery series system?
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.
