BATTERY PACK AND VEHICLE - A simplified explanation of the abstract
This abstract first appeared for US patent application 18200234 titled 'BATTERY PACK AND VEHICLE
Simplified Explanation
The patent application describes a battery pack consisting of multiple battery cells stacked together and housed in a case.
- The battery cells are arranged in a specific order, with an endmost cell at one end, followed by a first cell and then a second cell.
- The case is designed in a way that the thermal resistance between the endmost contact portion (which touches the endmost cell) and the first contact portion (which touches the first cell) is higher than the thermal resistance between the second contact portion (which touches the second cell) and the first contact portion.
Original Abstract Submitted
A battery pack includes a plurality of battery cells stacked together, and a case that accommodates the battery cells. The battery cells include an endmost cell disposed at a farthest end on one side in a stacking direction, a first cell disposed adjacent to the endmost cell, and a second cell disposed adjacent to the first cell. Further, the case is configured such that a thermal resistance between an endmost contact portion that is a portion in contact with the endmost cell and a first contact portion that is a portion in contact with the first cell is higher than a thermal resistance between a second contact portion that is a portion in contact with the second cell and the first contact portion.
