Problems solved by technology

[0003] With the development of social economy, more and more people start to use electric vehicles for travel, but there are also some problems in the use of electric vehicles. During the charging and discharging process of lithium-ion battery system, the temperature of the battery surface will inevitably increase. When the temperature rises and the temperature is too high, it will cause the insulation alarm of the battery system. In serious cases, it will cause the battery to burn and explode, which will bring safety hazards

Abstract

The invention discloses a battery cooling device for an electric vehicle, which belongs to the technical field of battery cooling. An electric vehicle battery cooling device, comprising a base, a connecting plate, a supporting plate and a battery, the supporting plate is connected above the base through the connecting plate, the battery is connected to the top of the base, and the top outer wall of the supporting plate is connected with a first Motor, the outer wall of the output end of the first motor is connected with a rotating shaft, the first motor is connected with a transmission mechanism through the rotating shaft, the outer wall of the transmission mechanism is connected with a fixing plate, and the end of the transmission mechanism far away from the first motor is connected with a fan The fan blade is matched with the battery; the invention installs the fan blade on the outside of the battery, and by rotating the fan blade left and right, the blowing range of the fan blade is expanded, thereby increasing the area where the battery is blown, which is beneficial to reduce the battery temperature.

Description

technical field [0001] The invention relates to the technical field of battery cooling, in particular to an electric vehicle battery cooling device. Background technique [0002] An electric vehicle refers to a vehicle that is driven by a vehicle-mounted power supply and driven by a motor to drive the wheels, and meets the requirements of road traffic and safety regulations. Devices, etc., have less impact on the environment than traditional cars, and their prospects are widely optimistic. Compared with traditional cars, they have many advantages, such as zero or near-zero emissions, reducing water pollution caused by oil leakage, and reducing greenhouse gas emissions. Gas emission and smooth operation without noise. [0003] With the development of social economy, more and more people start to use electric vehicles for travel, but there are also some problems in the use of electric vehicles. During the charging and discharging process of lithium-ion battery system, the tem...
