On July 3, Xiaomi Auto Technology Co., Ltd. revealed a new patent titled "Battery Pack Case, Battery Pack, and Electrical Equipment." This patent pertains to the design of a battery pack case, incorporating a dedicated compartment for housing multiple battery cell units. A key feature of this design is the inclusion of multiple independent first gas channels within the battery pack case. Each battery cell unit is connected to the exterior via its own dedicated gas channel, facilitating independent thermal management. This innovative approach aims to contain thermal runaway events within a specific battery cell unit, effectively preventing the spread of thermal runaway to other units. As a result, the normal operation of unaffected battery cell units remains undisturbed, significantly mitigating the risk of overall thermal runaway deterioration within the battery pack.
