Power battery for electric automobile

Abstract

The invention discloses a power battery for electric automobile. Multiple rows and multiple columns of individual cells are arranged in arrays between transverse heat-dissipating plates. A longitudinal heat-dissipating plate is arranged between two adjacent individual cells. Side faces of the transverse and longitudinal heat-dissipating plates are all provided with heat-dissipating aspirating holes, which are connected to a heat-dissipating suction pump. The side of the transverse heat-dissipating plate and the side of the longitudinal heat-dissipating plate, close to the individual cells, are provided with multiple air inlet holes. Through the heat-dissipating unit, the heat dissipation performance of a power battery can be greatly raised. As the heat-dissipating structure and the internal heat-dissipating channels are novel and ingenious, heat-dissipating capability can be greatly enhanced, usability of the cells can be greatly improved, and service life of the power battery is guaranteed. With the arrangement of a flame retardant, use safety of the battery is greatly raised, and a foundation is provided for development of electric automobile.

Description

technical field [0001] The invention relates to the technical field of electric vehicle battery charging, in particular to a power battery and a device for an electric vehicle. Background technique [0002] With the continuous increase of the number of cars in the world, on the one hand, the energy crisis caused by a large amount of fuel consumption has become increasingly serious, and on the other hand, the degree of environmental pollution caused by vehicle exhaust emissions has also become more and more serious. Therefore, many countries and regions in the world, including the United States, Japan, China, and Europe, are devoting themselves to the research of new energy vehicles. At present, the most effective and fastest-growing electric vehicles (including pure electric vehicles, hybrid electric vehicles and fuel cell electric vehicles, and one of the key technologies of electric vehicles are power batteries, on the one hand, the quality of batteries determines the qual...

Problems solved by technology

[0003] However, due to the high output power of electric vehicles, the battery is easy to heat up. If the temperature of the battery is high, it will not only easily cause damage to the power battery and affect the service life of the battery, but also has a great potential safety hazard. Therefore, for the power of electric vehicles For batteries, heat dissipation plays a very important role and is one of the technical problems that must be solved for the further development of power batteries
