Abstract
Li-ion batteries are widely used in electric vehicles for their superior
performance. To investigate a simple and efficient method for the Li-ion
power batteries, the cold plate with four types of structures A, B, C, and D
were established, respectively. Subsequently, the effects of micro-channel
thickness and width on the cooling performance of battery thermal management
systems were analyzed by using a numerical simulation method. The results
show that with the increases of the micro-channel thickness, the maximum
temperature (Tmax) of the cold plate is gradually increased under structures
A, B, and C, while it is gradually decreased under structure D. The standard
deviation of temperature (T?) of the cold plate of structure A was less
affected by the change of the micro-channel thickness. Under structures B,
C, and D, the temperature uniformity of the cold plate can be well
maintained when the micro-channel thickness was 1.0 [mm]. With the increase
of the micro-channel width, the Tmax and T? of the cold plate are gradually
increased in all cases, while the ?P from the inlet to outlet is gradually
decreased. The temperature uniformity of the cold plate is well maintained
by structure C. The decreasing amount and changing range of ?P caused by the
change of micro-channel width is smaller than caused by the change of the
thickness.
