Battery assembly and electric vehicle thereof

Abstract

The invention discloses a battery assembly. The battery assembly comprises a battery shell, and the top of an inner cavity of the shell is open and the inner wall is provided with a shock absorbing assembly. The shock absorbing assembly abuts against the inner and outer walls of a battery inner shell, and a battery is fixed into an inner cavity of the inner shell. The bottom of a heat dissipationgap communicates with one end of an air inlet pipe, and the top opening portion of the battery shell is assembled and sealed with a battery cover. The battery cover is provided with an exhaust pipe, and one end of the exhaust pipe communicates with the top of the heat dissipation gap. The inner cavity of the inner shell communicates with one end of a wire conduit, and the other end of the wire conduit penetrates out of the shell with the battery. An air blowpipe is fixed between heat dissipating protruding blocks, and the air blowpipe is provided with blow holes at the corresponding positionson both sides of the heat dissipation protruding blocks. One end of the air blowpipe communicates with a connecting pipe, and the other end of the air inlet pipe communicates with an exhaust port of avehicle-mounted air conditioner through a first air inlet pipe. The air inlet end of the vehicle-mounted air conditioner communicates with one of outlets of reversing air valves through a branch airpipe, and the connecting pipe communicates with one end of an air inlet manifold. The invention further discloses an electric vehicle to which the battery assembly is applied.

Description

technical field [0001] The invention relates to an electric vehicle, in particular to a battery assembly and the electric vehicle. Background technique [0002] Electric vehicles are currently a very mature new energy vehicle. Most countries in the world have banned the sale of fuel vehicles after 2030, so electric vehicles are bound to become the main means of transportation in the future. [0003] At present, compared with fuel vehicles, the main end plate of electric vehicles appears in the issue of battery life. At present, pure electric vehicles, such as Tesla, have a maximum battery life of about 400 kilometers, and then a tank of fuel can last up to 600-1000 kilometers. Kilometers and more, if you carry fuel or expand the fuel tank, the mileage may be doubled or more. [0004] The battery life problem of electric vehicles is mainly due to the battery. The battery has not made breakthroughs in recent decades, and its storage capacity per unit volume is not high, which...

[0003] At present, compared with fuel vehicles, the main end plate of electric vehicles appears in the issue of battery life. At present, pure electric vehicles, such as Tesla, have a maximum battery life of about 400 kilometers, and then a tank of fuel can last up to 600-1000 kilometers. Kilometers and more, if you carry fuel or expand the fuel tank, the mileage may be doubled or more

[0004] The battery life problem of electric vehicles is mainly due to the battery. The battery has not made breakthroughs in recent decades, and its storage capacity per unit volume is not high, which leads to the inability to improve the battery life in a limited volume battery.
