An intelligent lithium battery working condition management system and its control method

Abstract

The invention discloses an intelligent working condition management system for a lithium battery. The intelligent working condition management system for the lithium battery is provided with a battery box filled with a heat-radiating medium inside; a plurality of placement cavities are vertically arranged in the battery box; the placemen tcavities are fixedly arranged at the bottom of the battery box in the form of a determinant matrix structure; gaps are arranged among all the placement cavities; the top of the battery box is provided with a sealing cover; a plurality of liquid injection branch pipes are hung on the sealing cover in an up-down manner; the liquid injection branch pipes extend into the gaps in the middle of every four adjacent placement cavities; the bottom of the battery box is provided with liquid outlet pipes; the liquid injection branch pipes are all provided with branch valves and are further communicated with a liquid injection header pipe; the liquid outlet pipes are connected with an input end of an automotive heat radiator through heat-radiating pumps; an output end of the heat radiator is connected with the liquid injection header pipe. The system is safe and reliable to use, and is high in the controllability to a work environment of the lithium battery; not only can the reliable cooling be realized, but also the heating can be carried out on the lithium battery in a low-temperature environment; a working condition environment of the lithium battery is guaranteed; the use safety, the reliability and the service life of the lithium battery are improved.

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.
