Abstract
A battery module includes a battery case, at least a battery, and at least a thermal pad. The battery case includes a top cover and a bottom cover. The battery is received in the bottom cover of the battery case. The thermal pad is placed in a chamber of the batteries and pressed by the top cover of the battery case after the top cover and the bottom cover covering together. Therefore, the thermal energy created by the battery module can be easily transmitted to the outside of the battery module case along the thermal pad.
Claims1
A battery module comprising:
- a battery case including a top cover and a bottom cover;
- two batteries received in the bottom cover of the battery case side by side;
- and
- a thermal pad engaged in a chamber between the two batteries, the thermal pad being supported on the two batteries and resting against a bottom of the top cover after the top cover and the bottom cover covering together for transmitting the thermal energy created by the two batteries outside the battery case;
- wherein the chamber is substantially V-shaped, the thermal pad has a substantially inverted triangle section to conform to the chamber among the two batteries and the top cover.
