Battery performance degradation due to high temperatures
It is said that temperature control of the battery is crucial to maintain battery
life span, safety, and performance stability in electric vehicles (EVs).
Repeated cycles of charging and discharging generate heat inside the cell
and in the connected system, which can cause degradation and fire.
Furthermore, trapped heat inside the battery pack or the imbalance in the
electricity due to temperature changes from module to module can affect
battery performance, therefore, it is necessary to release the heat inside the
battery and maintain a suitable temperature.
2-Component
Room Temperature-Curable Thermal-Conductive Greases
The CGW series of thermal conductive greases is a two-component silicone-
based thermal conductive grease. They contain very little low-molecular-
weight siloxane and are low-volatile materials.
They are low-specific-gravity materials, contributing to the weight reduction of automobiles. They have been used in EV batteries in Europe, and are
recognized for their high reliability.
