试验成功地重用铁路蓄电池系统的再生能量

2007年12月17日的东京 - 川崎重工业，有限公司今天宣布，利用带有Gigacell®的土地储存电池系统，它已成功完成对再生制动的能量的再利用验证测试，其专有镍金属 - 氢化物电池。

The Gigacell-driven system was tested at substations of the Osaka subway, with the cooperation of the Osaka Municipal Transportation Bureau and Kotsu Service Co., Ltd., Kawasaki verified that energy generated by a train’s braking could be stored and reused to compensate for the voltage fall-offs that occur during startup, operation and congested rush hours. This advance is expected to contribute to energy savings and a reduction in the environmental burden of train lines, as it will prevent a syndrome called “regeneration cancellation.” It will thus allow the entire railway system to operate on less energy, reducing the contracted electricity volumes with power companies and lowering the costs associated with opening new substations.

Kawasaki还在停电期间对紧急操作进行了测试，并确认电池系统使火车以较低的速度到达最近的车站，而不会影响空调或照明。

铁路电池系统由Kawasaki使用Gigacell，这是针对大规模应用程序定制的，具有快速充电/放电能力。这些特征允许Gigacell直接连接到架空线，而无需控制系统，并最小化充电/放电期间的功率损耗。因为它只有5.4米^3.在体积中，四个单位可以在变电站中并联安装。为了提高紧急情况下的安全性，电池系统还配备了负极和正端子上的高速直流断路器，以断开系统与架空线路的连接并防止短路。
