The invention discloses a battery thermal management optimization method and device, a readable storage medium and computer equipment. The method comprises the following steps: acquiring thermophysical parameters, design parameters and transmission performance parameters of grouped materials of single battery cells, and structural parameters and thermophysical parameters of a battery pack; constructing an electrochemical thermal coupling model and a three-dimensional battery pack thermal flow coupling model according to the obtained parameters, and calculating the heat production rates of thesingle batteries at different temperatures and different rates according to the electrochemical thermal coupling model; importing the heat production rates at different temperatures and different rates into a three-dimensional battery pack thermal flow coupling model, and solving the three-dimensional battery pack thermal flow coupling model to obtain the overall temperature field distribution ofthe battery pack; monitoring the temperature of the battery pack based on the temperature field distribution, and calculating the maximum temperature difference of the temperature change of each monitoring body and the maximum temperature difference of the battery system; and when the maximum temperature difference of the monitoring body and the maximum temperature difference of the system are notin the corresponding design range, changing the design parameters.
Description
technical field [0001] The present invention relates to the technical field of batteries, in particular to a battery thermal management optimization method, device, readable storage medium and computer equipment. Background technique [0002] As the core component of new energy vehicles, lithium-ion power batteries have received continuous attention from consumers for their safety and cycle life. The power battery is used as the power source of electric vehicles. When the temperature is generally in the range of 20-45 ℃, its charging and discharging performance is the best, the life is the best, and the safety is the best. Therefore, the thermal management design of the battery pack is a key factor controlling the safety and performance of electric vehicles. [0003] In related technologies, the thermal management of battery packs is mainly based on the optimization of the air cooling system on a macro scale. This optimization method does not take into account the influenc...
