ENERGY STORAGE DEVICE MODULE

摘要

PURPOSE: An energy storage device module is provided to be variously applied according to applications by connecting energy storage device groups with a voltage equalization function to a single control part. CONSTITUTION: Plural energy storage devices(10) are serially connected. A voltage sensor(20) senses the voltage of the both ends of an energy storage device. A voltage equalizing part(30) bypasses extra current by being connected to the energy storage device in parallel. A controller(40) transmits the control signals to the voltage equalizing part. The energy storage device, the voltage sensor, and the voltage equalizing part are made of single group. The controller individually controls the connected voltage equalizing parts.
