Abstract

The invention provides an electric vehicle. The electric vehicle comprises a battery pack and a heat dissipation device for performing heat dissipation on the battery pack, wherein the heat dissipation device comprises a phase-change material heat dissipater and a heat dissipation tube embedded into the phase-change material heat dissipater; the phase-change material heat dissipater is in contact with the battery pack to form heat conduction; the phase-change material heat dissipater conducts heat of the battery pack to the heat dissipation tube; two ends of the heat dissipation tube extend from the phase-change material heat dissipater to a vehicle body of the electric vehicle respectively; a cooling liquid inlet and a cooling liquid outlet are formed in the vehicle body of the electric vehicle; when the electric vehicle stops running, cooling liquid is injected from the cooling liquid inlet, flows in the heat dissipation tube, and is drained from the cooling liquid outlet, so as to take the heat of the battery pack away from the vehicle body.

Description

technical field [0001] The invention relates to the field of automobiles, in particular to an electric vehicle, an infusion device adapted to the electric vehicle and a method for cooling the electric vehicle. Background technique [0002] With the continuous depletion of fossil energy and the widespread awareness of environmental protection and energy conservation and emission reduction, the rational and efficient use of energy has attracted widespread attention. Electric vehicles are driven by power batteries, which can reduce the consumption of fossil fuels. Compared with fuel vehicles, the greenhouse gas emissions can be reduced to 20%, so they have received more attention and application. Lithium-ion battery packs are widely used in the field of electric vehicles due to their high energy density, high average output voltage, and low self-discharge rate. However, the large current during the charging and discharging process of the battery pack, the compact space structu...
