The invention relates to the field of battery energy storage, in particular to a modular nickel-metal hydride battery energy storage system, which comprises a current transformation module, a power supply module, a power supply module and a power supply module, and the connecting device is used for connecting the direct current with the nickel-metal hydride battery and transmitting the electric energy into the nickel-metal hydride battery. A plurality of connecting devices are arranged, and the plurality of connecting devices are connected to the converter module in parallel; and the power distribution cabinet is used for connecting the converter module with the plurality of connecting devices. The power distribution cabinet is provided with a plurality of monitoring modules which are used for monitoring the voltage of the connecting device. The monitoring module can monitor the current of the connecting device. And a main circuit breaker is arranged in the power distribution cabinet and is used for disconnecting the converter module from the plurality of connecting devices. By arranging the connecting device, the electric leakage danger is avoided when the automobile approaches and collides.

    本发明涉及电池储能领域,特别是一种模块化镍氢电池储能系统,包括变流模块,用于与电网连接,将电网的交流电转换为直流电;连接装置,用于将直流电与镍氢电池连接,将电能传入镍氢电池内。所述连接装置设有多个,多个连接装置并联至变流模块上;还包括配电柜,用于将变流模块与多个连接装置连接。所述配电柜上安装有多个监测模块,用于分别监测连接装置的电压。所述监测模块能够监测连接装置的电流。所述配电柜内设有总断路器,用于将变流模块与多个连接装置的连接断开。本发明通过设置连接装置避免汽车靠近发生碰撞时,发生漏电危险。
