UltraBattery (Environmental Conservation Product)

UltraBattery (Environmental Conservation Product)

Capacitor hybrid lead-acid battery for the next-generation automobiles such as idling-stopping cars, mild HEVs (hybrid electric vehicles), along with instantaneous heavy load applications

Prototype UltraBattery
FTZ12-HEV
12V, 8.5Ah@5HR


Hybrid battery combining an ultra capacitor with the negative electrode of lead-acid battery


PSOC(partial state of charge) and rapid charge/discharge cycle life is four times that of conventional lead-acid battery

Capable of dealing with PSOC pulse charge/discharge cycles, overcoming a major difficulty in the past

Cycle life test under high-speed and hill-climbing running conditions (HEV running simulation)
