There’s an optimal temperature range for Li-ion batteries in electric vehicles (EVs). It lies between about 15° and 35° C. Outside of this range, performance suffers when charging and discharging the batteries. The major requirements for rechargeable … [Read more...]
Thermal barriers: More safety for electric cars, and now in 3D
In lithium-ion batteries, higher energy density increases the risk of thermal runaway. As a preventive measure, Freudenberg Sealing Technologies has developed thermal barriers that help to slow down thermal runaway by increasing resistance to … [Read more...]
EV battery thermal management challenges
Keeping EV batteries cooled is the most common thermal management concern. However, batteries used in cold climates often benefit from being heated when temperatures fall. When undergoing fast charging or extra fast charging (XFC) batteries may need … [Read more...]
