Automatic heat dissipation battery and power supply system of electric vehicle

Abstract

The invention provides an automatic heat dissipation battery and a power supply system of an electric vehicle, and relates to the technical field of energy storage. The automatic heat dissipation battery comprises a battery box main body, a battery module, a heat dissipation component and a monitoring unit, wherein the battery module is arranged in the battery box main body, a gap is formed between the battery module and the battery box main body, a first ventilation passage is formed in the top of the battery box main body, a second ventilation passage is formed in the bottom of the battery box main body, the heat dissipation component is arranged at one end of the first ventilation passage, and the monitoring unit is arranged on the battery box main body and is electrically connected with the heat dissipation component. The power supply system of the electric vehicle comprises the automatic heat dissipation battery. The invention aims to provide the automatic heat dissipation battery and the power supply system of the electric vehicle, which are used for solving the problem that the battery in the prior art is low in heat dissipation efficiency to cause relatively high temperature in the battery box and the problem that a severe working environment cannot be met due to the adoption of a shuttle window heat dissipation structure.

Description

technical field [0001] The invention relates to the technical field of energy storage, in particular to a self-radiating battery and an electric vehicle power supply system. Background technique [0002] The technical key of electric vehicles and energy storage products is the battery. The performance of the battery directly determines the performance, safety and service life of the electric vehicle and energy storage products. Since the temperature will directly affect the safety performance and life of the battery, over If it is too high, it will cause a safety accident, so how to keep the internal temperature of the battery from being too high becomes very important. [0003] At present, the battery box generally adopts a louver heat dissipation structure, which cannot meet some harsh working environments, so that the dustproof and waterproof performance requirements of the battery box cannot be guaranteed. [0004] Based on the above problems, it is particularly importa...
