THERMAL MANAGEMENT OF ELECTRICAL STORAGE DEVICES BY COOLANT POOL

摘要

A battery system including a passive cooling system for cooling a plurality battery cells during normal operation and during overheating of the battery cells. The passive cooling system may include a housing, a cooling fluid (coolant pool) within the housing, and a plurality of dividers between each of the plurality of battery cells.

主权项

1. A battery system, comprising:
a sealed housing; at least a first battery cell and a second battery cell, wherein the first battery cell and the second battery cell are sealed within the housing; at least one divider sealed within the housing and interposed between the first battery cell and the second battery cell, wherein the at least one divider is spaced apart from a top surface of the sealed housing by a first gap and from a bottom surface of the sealed housing by a second gap; and a dielectric cooling fluid sealed within the housing, wherein the cooling fluid physically contacts the first battery cell, the second battery cell, the at least one divider, and the housing.
