Development of Advanced Battery Systems for vehicle Applications 890783

The Advanced Battery Business Unit (ABBU) of Johnson Controls, Inc. Is developing several promising advanced battery technologies including flow-through lead-acid, zinc/bromine, and nickel hydrogen. The flow-through lead-acid technology, which is being developed under Department of Energy (DOE) sponsorship, is progressing towards the fabrication of a 39 kWh battery system. Recent efforts have focused on achieving the aggressive specific energy goal of 56 Wh/kg in 12 volt module form. Recent DOE sponsored work in the zinc/bromine program has focused on the development of a proof-of-concept 50 kWh electric vehicle system for a light van application. Efforts in the nickel hydrogen program have focused on reducing system cost in order to make the “life-time” premium market and EV market possible targets. The status and future direction of each of these programs are summarized.
