Thickness of energy storage pack water cooling plate

What is a liquid cold plate?

Liquid cold plates can be customized in a wide range of geometries, sizes, and manufacturing methods based on requirements and use. Electric Vehicle cold plates are typically thin (< 15 mm thickness) with a very large surface area to accommodate all the batteries. Due to cost and weight constraints, aluminum is the material of choice.

What is a channeled liquid cooling thermal management system of lithium-ion battery pack?

A channeled liquid cooling thermal management system of Lithium-ion battery pack for electric vehicles to study the thermal behaviour, and hence to investigate the effects of discharge rates and the heat exchange area between neighbouring batteries is discussed in .

What coolant is used in a battery cold plate?

The coolant used is a 30-70 mixture of ethylene glycol and water with a flow rate of 5 liters per minute (LPM) at an inlet temperature of 20C. These chosen values are typical of battery cold plates in practical applications. Fig. 2. Schematic of baseline battery cold plate showing top view (above) and side view (below) with flow baffles

What is a typical battery cold plate?

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.

What is the maximum temperature of a battery cold plate?

The maximum temperature of the cold plate was around 27C and the surface temperature variation Tmax was around 5.4C, both within the typical performance requirements of battery cold plates. The fluid temperature rise from inlet to outlet is around 3.1C.

How to design and optimize cold plates for EV batteries?

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.
