Active BMS

Ensol’s patented (Patent US 9,948,115) High Energy Transfer Active Battery Management System (BMS) is a technology that makes an already efficient lithium battery even more productive.

Unlike in other lithium batteries, in EnSol Active™ energy is balanced among cells based on induction at a rate 150 times higher (up to 30A). The transfer current is driven by the voltage differential between cells. Thus, the maximum cell capacity utilization becomes possible. Importantly, the system supports weaker cells with higher internal resistance. Transfer happens among all cells simultaneously and occurs during charge, discharge, and stand-by period. Transferring charge among cells at 30A provides 10-20% higher available capacity and 50% longer lifetime.
