Presented are thermomechanical fuses for mitigating heat propagation across electrochemical devices, methods for making and methods for using such fuses, and traction battery packs with load-bearing, sacrificial thermomechanical fuses to help prevent thermal runaway conditions. A battery assembly includes an electrically insulating battery housing with multiple battery cells disposed inside the battery housing. These battery cells are electrically interconnected, in series or parallel, and stacked in side-by-side facing relation to form adjacent, mutually parallel stacks of battery cells. Thermomechanical fuses thermally connect neighboring stacks of the battery cells. Each thermomechanical fuse is formed, in whole or in part, from a dielectric material that undergoes deterioration or deformation at a predefined critical temperature; in so doing, the thermomechanical fuse thermally disconnects a first stack of cells from a neighboring second stack of cells.

A cold ambient battery chilling mode of an electric vehicle may be implemented if the vehicle battery is being charged when the ambient air temperature is low and a temperature of the battery is elevated. During cold ambient charging, coolant flows through a heater core and through a battery heat exchanger. Cold ambient air may be utilized to cool the coolant flowing through the heater core, and coolant from the heater core flows through the battery heat exchanger and cools the battery during charging. A battery chiller may be deactivated when the cold ambient battery chilling mode is activated to reduce energy consumption.

Electrochemical cell battery system and associated methods of operation are provided based on the incorporation of a thermal suppression construct including a supply of cooling fluid dispensed in intimate contact with the cells disposed within an enveloping sealed enclosure. The electrochemical cells are connected electrically by bus bars to form a battery of cells. The bus bars support cooling by convection methods. The cells are allowed to float mechanically as they are charged and discharged while maintaining intimate thermal contact with the enveloping sealed enclosure through conduction and the bus bars through conduction. The system provides a method of cooling the cells by conduction and convection and that accommodates mechanical changes to both the cells and the enveloping sealed enclosure.

A collector plate assembly includes a collector plate and a collector plate support, the collector plate having a welding part for welding to a terminal of a battery unit, and the collector plate being installed in the collector plate support in such a way that the welding part is exposed by the collector plate support. A battery pack includes a housing; a battery support, enclosed by the housing and supported in the housing, the battery support being electrically connectable to an electric tool to supply electric power to the electric tool; and a collector plate assembly including a collector plate support and a collector plate installed in the collector plate support.

The battery rack includes: a plurality of battery modules; a rack case configured to store the plurality of battery modules; a control unit configured to control charging and discharging of the plurality of battery modules; a data storage unit including a cable configured to transmit data from the control unit and a data recording unit configured to store the data; and a storage unit including an accommodating case having an inside space for accommodating the data recording unit, a plurality of ventilation holes formed by opening a portion of the accommodating case so that the inside space and the outside are communicated with each other, and a cover portion that has a plate shape, is spaced apart from the plurality of ventilation holes by a predetermined interval, and is configured to cover the plurality of ventilation holes.

Battery packs for aircraft are provided, as are aircraft comprising such battery packs. One such battery pack comprises: a housing enclosing a plurality of battery cells; and an air channel. The air channel is connectable to an aircraft air inlet and an aircraft air outlet whereby, during flight of the aircraft, air enters the aircraft through the air inlet, passes through the battery pack air channel and exits the aircraft through the air outlet. At least a portion of a surface of the air channel is in thermal contact with the battery cells, whereby air flowing through the air channel exchanges heat with the battery cells through the surface of the air channel without entering the housing and contacting the battery cells.
