Vehicle lithium battery working condition management system and control method thereof

Abstract

The invention discloses a lithium battery working condition management system for a vehicle. The lithium battery working condition management system is provided with a battery box, wherein the interior of the battery box is filled with a heat dissipation medium; multiple placement cavities are vertically placed in the battery box; the placement cavities, with row-column matrix arrays, are fixed at the bottom of the battery box; gaps are formed between the placement cavities; a sealing cover is arranged on the top of the battery box; multiple liquid injecting branch pipes are arranged on the sealing cover in a suspension manner up and down; the liquid injecting branch pipes extend into the gaps between every adjacent four placement cavities; a liquid outlet pipe is arranged at the bottom of the battery box; each liquid injecting branch pipe is provided with a branch pipe valve and connected with a liquid injecting general pipe; the liquid outlet pipe is connected with the input end of a vehicle heat radiator through a heat dissipation pump; and the output end of the heat radiator is connected with the liquid injecting general pipe. The lithium battery working condition management system is safe and reliable in use, high in controllability on the lithium battery use environment, can reduce temperature reliably, and can heat the lithium battery in a low-temperature environment, so that the working condition environment of the lithium battery can be ensured, and the safety and reliability in use of the lithium battery are improved, and the service life of the lithium battery is prolonged.

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.

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.
