Abstract

The invention relates to a vehicle lithium battery cooling method, which comprises the following steps: acquiring the working current, end-circuit voltage and open-circuit voltage of a circuit where a vehicle lithium battery is located, calculating the difference value between the end-circuit voltage and the open-circuit voltage to obtain the working voltage of the vehicle lithium battery, measuring the battery volume and the current working temperature of the vehicle lithium battery, calculating the heat generation rate of the vehicle lithium battery according to the current working temperature, the battery volume, the working voltage and the working current, calculating the total heat conduction resistance of a fluorinated liquid and the vehicle lithium battery, constructing an energy conversion formula of the heat generation rate and the heat conduction resistance, and adjusting the liquid volume of the fluorination liquid by using the energy conversion formula to complete cooling of the vehicle lithium battery. The invention further discloses a vehicle lithium battery cooling device based on the fluorinated liquid, electronic equipment and a storage medium. According to the invention, the phenomenon of resource waste caused by too much fluorination liquid injected into the vehicle lithium battery can be solved.

Description

Technical field [0001] The present invention relates to the field of automotive manufacturing, in particular to a lithium-based vehicle cooling method, apparatus, and computer electronic apparatus-readable storage medium fluoride solution. Background technique [0002] As technology advances, businesses are booming, especially in the automotive sector, from gasoline and diesel vehicles gradual transition to hybrid, new energy vehicles, of which hybrid, new energy vehicles, lithium battery depends on the car, and the car during use of lithium batteries, lithium is especially important for the cooling of the vehicle. [0003] The most commonly used method of cooling a lithium battery car, mainly infusate lithium fluoride surrounding the vehicle, the vehicle can effectively achieve the cooling of the lithium battery, but generally the fluorinating liquid injection method, merely repeated injection Fluorinert cooled and did not consider the effects of heat and energy to convey the ra...
