摘要： A battery system is provided. The system includes a channel plate of which one side surface is contacted with a battery module and includes a cooling channel therein in which refrigerant circulates to cool the battery module. A first end plate supplies the refrigerant transmitted from the outside through an inflow port to the channel plate and transmits the refrigerant passing through the channel plate to the outside through an outflow port and is coupled to the channel plate to form a space surrounding the battery module. A second end plate is coupled to the channel plate opposite the first end plate to form the space surrounding the battery module. A cover plate is coupled to the first end plate and the second end plate opposite the channel plate to form the space surrounding the battery module.

摘要： Disclosed herein is a safety apparatus for a battery module of an electric vehicle preventing an entire electrode of a battery cell from fracturing due to a swelling expansive force upon overcharging, the apparatus including an end plate and a power supply unit. The end plate is disposed at ends of both sides of a battery module, includes an opening, and delivers an expansive force generated in the battery module to the exterior through the opening upon swelling. The power supply unit is disposed in the end plate and interrupts a current supplied to the battery module using the expansive force delivered through the opening.
