The bq78PL116 master gateway battery controller ispart of a complete Li-Ion control, monitoring, andsafety soluTIon designed for large series cell strings.The bq78PL116 along with bq76PL102 PowerLAN™dual-cell monitors provide complete battery-systemcontrol, communicaTIons, and safety funcTIons for astructure of three up to 16 series cells. ThisPowerLAN system provides simultaneous,synchronized voltage and current measurementsusing one A/D per-cell technology. This eliminatessystem-induced noise from measurements and allowsthe precise, conTInuous, real-time calculation of cellimpedance under all operating conditions, evenduring widely fluctuating load conditions.PowerPump technology transfers charge betweencells to balance their voltage and capacity. Balancingis possible during all battery modes: charge,discharge, and rest. Highly efficient charge-transfercircuitry nearly eliminates energy loss while providingtrue real-time balance between cells, resulting inlonger run-time and improved cycle life.
