Title: Dooseong Choi: Battery Pack Cooling Innovations.

Introduction.

Dooseong Choi is an inventor based in Daejeon, South Korea, whose patent work includes designs for improving coolant flow in middle- and large-sized battery pack cases. He is associated with LG Chem, Ltd. His listed portfolio includes 5 patents.

Latest Patents.

Choi’s latest listed patents address coolant distribution in battery pack cases containing modules made of stacked, rechargeable battery cells. Both describe coolant flowing across the module, perpendicular to the cells’ stacking direction, from an inlet port toward an outlet port.

One patent improves coolant-flow distribution by making the inlet duct’s vertical cross-sectional area smaller than the outlet duct’s. This configuration is intended to promote more uniform coolant flow through the battery pack.

A related patent describes one or more guide members in the inlet duct. These members direct coolant parallel to the cells’ stacking direction, helping guide its flow through the battery module.

Career Highlights.

The listed inventions focus on battery thermal management, particularly the design of ducts and flow paths within battery pack cases. Their stated aim is to improve the distribution of coolant around battery cells.

Collaborations.

Sang Phil Han and Jaesung Ahn are identified as Choi’s coworkers. The supplied information does not specify their roles or whether they collaborated with him on the listed patents.

Conclusion.

Dooseong Choi’s listed patent work centers on battery pack case designs that guide coolant flow through stacked-cell modules, with the goal of improving cooling distribution.
