Abstract

Disclosed herein are a device and a method for stabilizing voltage of an energy storage. The device for stabilizing voltage of an energy storage includes: a bypass unit connected to a unit cell in parallel; a controller connected to the unit cell in parallel to monitor voltage of the unit cell and connected to the bypass unit to control turn on / off of the bypass unit; and an analog circuit unit connected to the unit cell in parallel to detect the voltage of the unit cell and turning on the bypass unit when the detected voltage is higher than a preset second reference voltage.
