Abstract
A battery module includes a first cell stack and a second cell stack each including one or more battery cells, a mono frame receiving the first cell stack and the second cell stack, a spring located between the first cell stack and the second cell stack, a first plate located between the first cell stack and the spring, and a second plate located between the second cell stack and the spring, and a compression direction of the spring is parallel to a stack direction of the one or more battery cells in the first cell stack and of the one or more battery cells in the second cell stack.
Claims7
A battery module comprising:
- a first cell stack and a second cell stack each including one or more battery cells;
- a mono frame receiving the first cell stack and the second cell stack;
- a spring located between the first cell stack and the second cell stack;
- a first plate located between the first cell stack and the spring;
- a second plate located between the second cell stack and the spring;
- and
- a busbar frame received in the mono frame together with the first cell stack and the second cell stack,
- wherein at least one of the first plate and the second plate comprises a heat transfer member,
- wherein the spring is coupled to the first plate and the second plate by an adhesive agent,
- wherein the busbar frame includes an upper frame located on the upper sides of the first cell stack and the second cell stack, a front surface frame located on front surfaces of the first cell stack and the second cell stack, and a rear surface frame located on rear surfaces of the first cell stack and the second cell stack,
- wherein a compression direction of the spring is parallel to a stack direction of the one or more battery cells in the first cell stack and of the one or more battery cells in the second cell stack,
- wherein the mono frame is a single plate extending continuously so as to surround the first and second cell stacks and has an opened front surface and an opened rear surface, and the first cell stack, the second cell stack, and the busbar frame are received into the opened front surface and the opened rear surface of the mono frame,
- wherein the first cell stack and the second cell stack are configured to be received in the mono frame where the spring is in a compressed state,
- wherein a thermistor is located at least one of between the first cell stack and the first plate and between the second cell stack and the second plate in the stack direction, so as to directly contact the one or more battery cells, and
- wherein the thermistor is attached to the one or more battery cells by an elastic force of the spring.
