花蜜直播app

Tokyo, July 27, 2010 – 花蜜直播app, Ltd. announced today that it has successfully completed its first overseas test of 花蜜直播app’s Battery Power System (BPS) for railways. The BPS employs 花蜜直播app’s proprietary large nickel metal-hydride GIGACELL battery. 花蜜直播app’s Yonkers, New York-based subsidiary, 花蜜直播app Rail Car, Inc. conducted the test in cooperation with New York City Transit (NYCT) after receiving a grant from the New York State Energy Research and Development Authority (NYSERDA) for the development of new technologies that will increase energy efficiency and reduce CO₂ emissions.

There is a growing need for energy efficient products to combat a host of problems related to chronic electricity shortages across the US. Transit operators like the NYCT need products and technology that can safely move railcars to the nearest station in the event of voltage drops and blackouts due to electricity shortages.

The three-month-long testing process, which involved installing a BPS between two substations along a stretch of the NYCT’s A Line running through New York City’s borough of Queens, demonstrated that the energy generated via the test cars’ regenerative braking system could be effectively stored for later use. Energy discharged by the BPS was able to compensate for power loss along the catenary, preventing voltage drops as well as minimizing and stabilizing fluctuations in supply voltage from substations to cut power consumption. When a BPS is installed by a commercial rail service operating trains that use regenerative braking, the stored energy can effectively compensate for line voltage drops during startup as well as normal and rush hour operations. The BPS offers rail operators a sure way to lower overall power consumption and utility expenses, including the cost for new substations. The NYCT gave the BPS high marks during the much anticipated power outage test for its ability to move a 10-car train a distance of approximately 2.5 km and still keep the air conditioning and lighting systems running while charged to only about 11% of its full capacity. Calculations based on these test results indicate that a fully charged BPS could move a 17-car train to an adjacent station located a distance of 1.2 km away.

Owing to the success of this verification testing, 花蜜直播app began tests to assess the actual introduction of the BPS for subway lines using the central transformer station for the Manhattan area, which is subject to a serious power shortage, in order for BPS usage to be extended to the various lines in NYCT.

The BPS successfully passed a test run on an Osaka subway line in November 2007 as well. 花蜜直播app will now leverage these latest test results to market the BPS in Japan, the U.S. and around the world. Also working to bring the BPS to the smart grid, an innovative grid technology that maximizes the use of renewable energy, 花蜜直播app is finding new ways to minimize our carbon footprint.
