摘要： A battery, an electric apparatus, and a battery assembling method are provided. The battery includes: a plurality of battery cells; a strap-shaped member disposed fixedly relative to the plurality of battery cells; an electrical connection member located adjacent to the strap-shaped member; and a trough-shaped member, integrally having at least a first accommodation trough and a second accommodation trough, where the strap-shaped member is accommodated in the first accommodation trough, the connection member is accommodated in the second accommodation trough, and a portion of the trough-shaped member is located between the strap-shaped member and the battery cells. The trough-shaped member fastens the electrical connection member relative to the battery cells, avoiding fracture of the electrical connection member due to fatigue caused by high-strength loads. The electrical connection member can also be isolated from a wire harness and an ambient metal member, isolating and protecting the electrical connection member.

摘要： A battery case includes a first cell accommodating portion that accommodates a first number of battery cells, and a second cell accommodating portion that accommodates a second number of battery cells, smaller than the first number. The second cell accommodating portion is shorter than the first cell accommodating portion in one of three directions parallel to sides of the battery case. The battery case further includes a board accommodating portion, which is adjacent to the second cell accommodating portion in the one of the three directions, and that accommodates a circuit board therein; a first partition wall arranged between the first cell accommodating portion and the board accommodating portion; and a second partition wall arranged between the second cell accommodating portion and the board accommodating portion. Thus, the thickness of the battery is reduced and the circuit board is separated from the battery cells.
