Rechargeable lithium-ion and other such battery chemistries can be affected by temperature extremes. These conditions are much more likely to occur during fast charge, discharge or in locations where ambient temperatures are high and can affect efficiy and lifespan. Often, active cooling strategies, such air conditioning, are used. However this is energy intensive and can reduce driving range significantly.
CrodaTherm™ bio-based ambient or high temperature phase change materials can be utilised in a passive or hybrid cooling system, to absorb this heat and manage “hot spots”, improving battery life, efficiency and reducing the risk of thermal runaway.
In cooler ambient temperatures, PCMs can be used to manage residual heat in the battery pack after charging or driving, to help slow the rate of cooling. The next time the car is driven the battery is at or around the optimum temperature, reducing or eliminating the need for additional electric heating.
