In an electric drive vehicle (EDV), the torque is supplied to the wheels by an electric motor that is powered by a battery, or by a combination of a battery and an internal combustion engine (ICE).
Nickel-Metal Hydride (NiMH) batteries are the predominant technology used in HEVs today. However, they offer insufficient power or energy performance to support emerging HEVs, PHEVs, and BEVs that have a longer electric-only driving range. For these applications, lithium-ion batteries are the ideal solution – delivering an optimal combination of high power, long cycle life, and reduced battery weight.
Compared to NiMH batteries, lithium-ion batteries provide many advantages in EDV applications:
With features including oxidation resistance and zero TD shrinkage, Celgard® Monolayer PP and Trilayer PP/PE/PP separators provide excellent chemical stability, high temperature integrity, and extended cycling performance in EDV lithium-ion battery applications.
