Optimization of Cooling Structure of Water-Cooled High-Power Power Battery Pack
The high-power battery for vehicles has a large discharge rate and rapid heat generation,and is prone to overheating of the battery cell.In order to optimize the discharge temperature control capability of the water-cooled high-power battery mod-ule,a parametric analysis of the cooling structure was carried out.The electric-thermal coupling calculation model of the battery module is established,and based on the calculation model,the four-factor and four-level orthogonal test of the four key param-eters of the cooling liquid inlet temperature T,the cooling liquid flow rate V,and the width W and height H of the cooling pipe is calculated.influence.On the basis of the weight calculation results,combined with the response target histogram and the cell sur-face temperature distribution map,the optimal solution Ⅰ of the whole group was determined.
