Abstract:
A battery spacer is provided. The battery spacer (2) comprises a first spacing plate (22) and a second spacing plate (22') aligned with and spaced from each other in a longitudinal direction and a plurality of beams (211) parallel to and spaced from each other in a transverse direction. Each beam (211) is connected between the first and second spacing plates (22, 22) in the longitudinal direction and protrudes outwardly from a plane formed by back surfaces of the first and second spacing plates (22, 22). The beams (211) are configured to securely receive at least tabs of cell cores between neighboring beams (211). A battery protecting device and a power battery are provided as well.
Abstract:
A fuse includes an upper shell, a lower shell and a cavity formed by the upper shell and the lower shell; first and second conductors which are respectively disposed between the upper shell and the lower shell. The first ends of each conductors are disposed in the cavity and form a clearance. The second ends of the conductors extend out from the cavity. A conductive bar is welded to the first and second conductors to form a first weld line and a second weld line.
Abstract:
A method of preparing aluminum alloy-resin composite and an aluminum alloy-resin composite obtained by the same are provided. of the method comprises: S1: anodizing a surface of an aluminum alloy substrate to form an oxide layer on the surface, the oxide layer including nanopores; S2: immersing the resulting aluminum alloy substrate obtained in step S1 in a buffer solution having a pH of about 10 to about 13, to form a corrosion pores on an outer surface of the oxide layer; and S3: injection molding a resin onto the surface of the resulting aluminum alloy substrate obtained in step S2 in a mold to obtain the aluminum alloy-resin composite.
Abstract:
A mthod of metalizing a surface of an insulation substrate includes: applying an ink composition onto the surface to form an ink layer; subjecting the insulation substrate to heat treatment at a temperature of about 500 to 1000 degrees Celsius in a non-reactive atmosphere; plating a metal layer on the ink layer. The ink composition comprises a metal compound and an ink vehicle. The metal compound includes at least one selected from a group consisting of a nano-copper oxide, a nano-cuprous oxide, a compound of formula I, and a compound of formula II, TiO2-σ(I), M1M2pOq (II), 0.05≦σ
Abstract:
A battery explosion-proof device battery explosion-proof device includes a valve body, a rupture plate, and a protecting cover. The valve body includes a base portion and a shaft portion connected with the base portion. The shaft portion may be formed with threads on an external circumferential surface thereof and with a venting passage. The rupture plate may be disposed inside a concaved portion of the base portion for sealing the venting passage. The protecting cover covers the concaved portion.
Abstract:
A hydraulic system of an electric vehicle may comprise: an oil container (1); a first and a second clutch driving circuits (L1, L2) connected in parallel; an internal pump (5) driven by a driving system of the electric vehicle; a fifth check valve (8) connected in series at an outlet side of the internal pump (5); an external pump (13) driven by an external pump motor (M); and a sixth check valve (14) connected in series at an outlet side of the external pump (13). The fifth check valve (8) and the internal pump (5) connected in series and the sixth check valve (14) and the external pump (13) connected in series may be connected in parallel between the oil container (1) and the first and second clutch driving circuits (L1, L2). A driving system and an electric vehicle comprising the same may also be provided.
