    GE dual battery management system in Proterra bus

    http://finance.yahoo.com/news/ge-demonstrates-battery-dominant-fuel-174100005.html

    Researchers at GE Global Research, the General Electric Company’s (GE) technology development arm, have achieved a first step in reducing the cost of clean fuel, zero emission buses, with a vehicle powered by GE’s new Durathon™ battery in tandem with a lithium battery and a hydrogen fuel cell. This promising development of a new energy management system could help accelerate both fuel cell acceptance and electrification of bus fleets, delivery trucks and other larger, heavy-duty vehicle fleets enabling clean vehicle technologies. To see a video demonstration of the bus – click here –.
    In 2010, the GE team first successfully demonstrated a dual battery system on a zero tailpipe emissions hybrid transit bus by pairing a high-energy density sodium battery with a high-power lithium battery. Now, two years later, further testing using GE’s new Durathon™ battery has produced even better results. GE researchers believe that the kind of energy management architecture they’re building will allow for a bus to operate at full performance with a significantly smaller fuel cell than previously possible. The fuel cell power plant represents a significant cost and GE’s energy management system has the potential to bring down those costs by up to 50%.
