Abstract: The internal states of Lithium-ion batteries, notably state of charge (SOC), need to be carefully monitored during battery operation to manage energy and safety. In this paper, we propose an interval observer for SOC estimation in an electrically and thermally coupled parallel connection of cells. This is a particularly challenging problem because …
Understanding Parallel Charging. Parallel charging is a method of charging multiple Li-ion batteries at the same time. This means that instead of charging each battery individually, you can connect them together and charge them simultaneously. But before you jump into parallel charging, it''s important to understand how it works.

Connecting lithium-ion batteries in parallel or in series is not as straightforward as a simple series-parallel connection of circuits. To ensure the safety of both the batteries and the individual handling them, several important factors should be taken into consideration.
Connecting in parallel increases amp hour capacity only. The basic concept is that when connecting in parallel, you add the amp hour ratings of the batteries together, but the voltage remains the same. For example: two 6 volt 4.5 Ah batteries wired in parallel are capable of providing 6 volt 9 amp hours (4.5 Ah + 4.5 Ah).
