Abstract:
1. A battery spacer, comprising: a first spacing plate and a second spacing plate aligned with and spaced from each other in a longitudinal direction; a plurality of beams parallel to and spaced from each other in a transverse direction, each beam being connected between the first and second spacing plates in the longitudinal direction and protruding outwardly from a plane formed by back surfaces of the first and second spacing plates, wherein the beams are configured to securely receive at least tabs of electric cores between neighboring beams; a first side blocking plate connected between first longitudinal sides of the first spacing plate and the second spacing pate along the longitudinal direction, the first side blocking plate and the first longitudinal sides being perpendicular to the transverse direction, wherein the first side blocking plate faces a first outermost beam such that a first space is formed between the first side blocking plate and the first outermost beam, the first space adapted to receive a first tab of the electric cores; and a second side blocking plate connected between second longitudinal sides of the first spacing plate and the second spacing pate along the longitudinal direction, the second side blocking plate and the second longitudinal sides being perpendicular to the transverse direction, wherein the second side blocking plate faces a second outermost beam such that a second space is formed between the second side blocking plate and the second outermost beam, the second space adapted to receive a second tab of the electric cores, wherein a length of each of the first side blocking plate and the second side blocking plate in the longitudinal direction is greater than a first distance between proximal transverse sides of the first spacing plate and the second spacing plate, and smaller than a second distance between distal transverse sides of the first spacing plate and the second spacing plate, wherein one or more dove-shaped recesses are formed on each of the distal transverse sides of the first spacing plate and the second spacing plate respectively, wherein the proximal transverse sides of the first spacing plate and the second spacing plate extend along the traverse direction and are spaced from each other in the longitudinal direction, and wherein the distal transverse sides of the first spacing plate and the second spacing plate extend along the transverse direction and are spaced from each other in the longitudinal direction, and wherein a recessing portion is connected to an end of each of the first side blocking plate and the second side blocking plate, and a boss portion is formed on the recessing portion, the boss portion extended from the end of each of the first side blocking plate and the second side blocking plate.
