The active equalization of lithium-ion batteries involves transferring energy from high-voltage cells to low-voltage cells, ensuring consistent voltage levels across the battery pack and maintaining safety. This paper presents a voltage balancing circuit and control method.

It can be a strict low-voltage cutoff, a surge that exceeds the BMS limit, or a simple voltage drop in the cables. Treat this as a short, repeatable test plan. The inverter can click off when a compressor or pump starts.

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.

Instead of sending constant energy, they reduce the charge rate when the battery gets close to full. MPPT solar charge controllers are more advanced and efficient.
