H&EV markets are growing exponentially worldwide

The demand for Hybrid and Electric Vehicles (H&EV) is growing exponentially, with production generally doubling every year. When talking about H&EV, we're not only considering cars but the whole new generation of vehicles that revolution today mobility. It is estimated that by 2030, H&EVs on the road, will account for 15% or more of the cars in the world. As electronic and car battery technologies evolve and as the consumer demand for clean energy vehicles increase, experts consider even more H&EV on the global market. Major OEMs have committed to various platforms for H&EV in the next five years with a burst of start-ups globally also fueling this initiative.

Thermal Conductivity

Thermal Conductivity is the ability on a material to conduct heat through a material. Silicones offer solutions for flexible interface for thermal conductivity requirements with electrical insulation.

Heat dissipation is critical not just for reaching the desired levels of performance and reliability in EV applications when needed, but also to enable batteries to function for their intended lifetime. Much of the industry is moving to lithium-ion batteries to provide the power needed for EVs and the secondary power for hybrid vehicles, but without proper thermal management, batteries can overheat during charging or discharging.  There can also be a non-uniform temperature distribution within the battery packs which may affect optimal performance, ranging between 15°C and 35°C.  When the battery pack temperature exceeds this optimal range, the efficiency and durability may be strongly decreased.
