Automobile battery temperature control system and control method thereof

Abstract

The invention discloses an automobile battery temperature control system. The system is provided with a battery box which is internally filled with a heat-eliminating medium. A plurality of accommodation cavities are formed in the battery box vertically; the accommodation cavities are fixed to the bottom of the battery box in a row-column matrix structure; gaps are formed among the accommodation cavities; a sealing cover is arranged at the top of the battery box; a plurality of liquid injection branch pipes are vertically arranged on the top and the bottom of the sealing cover; the liquid injection branch pipes extend into gaps among every four adjacent accommodation cavities; a liquid outlet pipe is arranged at the bottom of the battery box; each liquid injection branch pipe is provided with a branch pipe valve and is communicated with a liquid injection main pipe; the liquid outlet pipe is connected to the input end of an automobile radiator via a radiating pump; the outlet end of the radiator is connected to the liquid injection main pipe. The system is safe and reliable to use and high in controllability of lithium battery using environment, and is capable of reliably reducing the temperature, heating the lithium battery under the low-temperature environment, ensuring the operating condition of the lithium battery, improving safety and reliability in use of the lithium battery, and prolonging the service life of the lithium battery.

Description

technical field [0001] The invention relates to the field of environmental temperature control for lithium batteries. Background technique [0002] With the development of microelectronics technology in the 20th century, miniaturized equipment is increasing day by day, which puts forward high requirements for power supply, and lithium batteries have entered a large-scale practical stage. Due to the large storage capacity, lightness and durability of lithium batteries, they are widely used in various electronic products. With the development of electric vehicles, lithium batteries are also widely used in electric vehicles, especially for vehicles that consume a lot of energy and use The environmental differences are quite large, and higher requirements are put forward for the use environment of lithium batteries. It is not only necessary to provide reasonable and reliable cooling of lithium batteries in high temperature environments, but also to heat lithium batteries in low ...

Problems solved by technology

Due to the large storage capacity, lightness and durability of lithium batteries, they are widely used in various electronic products. With the development of electric vehicles, lithium batteries are also widely used in electric vehicles, especially for vehicles that consume a lot of energy and use The environmental differences are quite large, and higher requirements are put forward for the use environment of lithium batteries. It is not only necessary to provide reasonable and reliable cooling of lithium batteries in high temperature environments, but also to heat lithium batteries in low temperature environments so that they can operate at a suitable temperature. However, there is currently a lack of such a system for controlling the environment of lithium batteries, which restricts the application and development of lithium batteries in the automotive field.
