A thermal interfacing assembly for use in a power module having at least one battery module and a cooling plate, and corresponding method of forming the thermal interfacing assembly. The thermal interfacing material is deposited over a first surface of the cooling plate such that the thermal interfacing material conforms to the shape of the first surface. The thermal interfacing material is configured to be electrically insulating and thermally conductive. A first embedded heater is positioned adjacent to the thermal interfacing material. The first embedded heater includes an electrically-conductive portion and a resistive portion. The battery module is installed adjacent to the first embedded heater such that the first embedded heater is directly in contact with a first face of the battery module. The first embedded heater is employed to at least partially induce in-place curing of the thermal interfacing material.

The present disclosure relates to a plate-like fluid container for the temperature control of an accumulator device for electrical energy or of an electrical consumer, for example in a motor vehicle, having two layers contacting one another at least regionally, an inlet for pouring a fluid into the fluid container, an outlet for discharging the fluid from the fluid container, and a fluid channel system arranged between the layers that connects the inlet to the outlet and is configured to be flowed through by the fluid during the temperature control, wherein a spacing of at least two first channel sections of the fluid channel system extending parallel to one another is larger in a first region of the fluid channel system disposed upstream than a spacing of at least two second channel sections of the fluid channel system extending parallel to one another in a second region of the fluid channel system disposed downstream to improve the temperature control performance of plate-like fluid containers for temperature control.

A battery pack, a battery module including the battery pack, and a power supply device including the battery module. The battery pack includes: a type-1 battery cell; and a series of type-2 battery cells which have an output power and a capacity different from an output power and a capacity of the type-1 battery cell and are arranged along a circumference of the type-1 battery cell to surround the type-1 battery cell. The series of type-2 battery cells are connected in parallel to the type-1 battery cell. The battery pack is a high-power, high-capacity battery pack capable of instantaneously outputting high power without a decrease in lifespan for a long time.

A multi-stage cascaded thermoelectrical cooler (TEC) package is used in conjunction with an air cooling system to control temperature of battery cells in a battery module such that the temperature differences stay within a predetermined range. Battery cells in the battery module are divided into one or more regular sections and one or more TEC enhancing sections. A regular section and a TEC enhancing section can use different types of battery cell holders to assemble the battery cells. TECs in the TEC package are integrated into each enhancing section, where each stage of the TEC package is attached to one or more battery cells in a different region of the enhancing section. A higher stage, which is more powerful in enhancing heat transfer and extracting heat from battery cells, is attached to one or more battery cells in a section closer to the air outlet. The TEC package is powered by a discharging convertor circuit of the battery module.
