A battery cooling plate is a flat component manufactured from thermally conductive materials like aluminum or copper. Its function efficiently removes excess heat generated during the battery's fast charging and discharging processes. Two simple schemes will show what is a cold plate and the main principles of thermal management.
A typical battery cold plate was chosen for this study with the dimensions of 250 x 500 x 10mm and a uniform heat load of 500W on both sides. The coolant used was a mixture of ethylene glycol and water. A simulation model was created using the commercially available CFD tool FloTHERM.
The thickness of the cooling plate is a critical factor that influences both thermal performance and structural integrity. A thicker plate generally provides better heat dissipation due to the increased material volume, which can absorb more heat.
Design and optimization of cold plates require tradeoffs between conflicting requirements including thermal resistance, pressure drop, and manufacturing constraints. In the case of EV batteries, it is also very important to consider the surface temperature uniformity of the cold plate.
