The utility model discloses a
battery pack, heat insulation subassembly and electric device, wherein,
battery pack includes casing, a plurality of battery
monomer and heat insulation subassembly, and casing defines and holds the cavity, and a plurality of battery
monomer arranges in the holding cavity along the first direction, and is equipped with heat insulation subassembly between at least two adjacent battery monomers, and heat insulation subassembly includes first board body, second board body and heat insulation board, and first board body and second board body respectively towards adjacent battery
monomer exert the action force away from each other, and heat insulation board is located between first board body and second board body. The
battery pack of utility model embodiment, through setting first board body and second board body to respectively towards adjacent battery monomer exert the action force away from each other, makes first board body and second board body can compress the battery monomer, is favorable to the effective transmission of
ion and
electron in battery monomer, can also avoid heat insulation board to be pressed to break down, guarantees the good heat insulation effect of heat insulation board.
