Kawasaki Rail Car, Inc.
Kawasaki Heavy Industries, Ltd. utilizing its patented high-capacity nickel-metal hydride battery, GIGACELL , developed the Battery Power System for railways to provide a solution for Energy Savings, Regeneration Cancellation, Peak Power Shaving, Line Voltage Stabilization, Alternatives to Substation, and Emergency Back-up Power.
With great capabilities in rapid charging and discharging, it can be installed onboard streetcars (LRV), inside the battery power system (BPS) for railways, or can be used for stabilizing output electricity generated from natural energies such as wind and solar power. Designed to be friendly to the environment, it is a battery committed to the efficient use of energy, and the reduction of CO2 emissions.
Kawasaki successfully tested the BPS at the Far Rockaway location in the New York City Transit (NYCT) system in 2010. The tests proved that the BPS stabilized the dramatic fluctuations in third rail voltage, efficiently captured the train regenerative energy, reduced the peak demand required and proved its ability to move many 10 car trains to the next station in emergency power outage conditions.
Building on the successful testing at New York City Transist, Kawasaki installed and tested the BPS in the Washington Metro Area Transit Authority (WMATA) system in 2103 and 2104. The tests proved that there was a 75VDC average line stabilization, up to 15.4% energy savings, up to 12.5% peak power reduction and as many as 19 fully loaded trains could each move more that ½ mile in a power outage condition. Details of these test can be found in the FTA report No. 086.
