摘要： Stackable battery assemblies and methods of use are disclosed herein. An example battery assembly includes an energy storage device, a housing having a locking unit, a receiver unit, and a sidewall that are interconnected to form an enclosure that retains the energy storage device. The locking unit can include a plate that is spaced apart from the sidewall of the housing by a second sidewall, the plate supporting a first electrical connector that is electrically coupled to the energy storage device via a locking member. The receiver unit can include a third sidewall that defines a cavity that is shaped to correspond with the locking unit, the third sidewall having a lock notch and a second electrical connector that is electrically coupled to the energy storage device.

摘要： 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.

摘要： According to the present invention, a dummy terminal is provided on a sensing substrate and sensing substrate may be thus commonly used on both side surfaces of a battery module, and as a result, since only one type of sensing substrate provided with the dummy terminal needs to be manufactured instead of manufacturing two types of sensing substrates having different arrangements of the substrate terminals, mass productivity of the sensing substrate and the battery module including the same may be significantly improved.
