GM heat pump recovers energy from EV battery to power heating & propulsion while helping conserve range: Ultium Energy Recovery

Green Car Congress

EV batteries, power electronics and other propulsion components produce heat. The Ultium Platform can recover and store this waste heat from the Ultium propulsion system. Ultium energy recovery is available on all current Ultium vehicles and planned for future Ultium vehicles.

New hydrogen storage material could enable smaller, cheaper, more energy dense systems for vehicles; Kubas binding

Green Car Congress

An international team of researchers, led by Professor David Antonelli of Lancaster University, has discovered a new material made from manganese hydride that could be used to make molecular sieves within hydrogen fuel tanks. The KMH-1 material also absorbs and stores any excess energy so external heat and cooling is not needed.

Volkswagen LCA highlights carbon benefits of EV vs diesel on Golf: 119 vs 140 g CO2/km; ID. family to reduce footprint

Green Car Congress

In the vehicle with an internal combustion engine, most of the emissions occur during the use phase—i.e., In contrast, most emissions from the battery-powered electric vehicle are generated in the productions phase. In addition, the electric vehicles offer a higher CO 2 -saving potential in all phases of the product cycle.

Penn State team devises new control strategy to enhance EV battery performance when driving in cold temperatures

Green Car Congress

Researchers at Penn State, with a colleague from EC Power, have devised a new control strategy that can rapidly restore EV battery power and permit full regeneration while driving at temperatures as low as −40 °C. The strategy involves heating the battery internally during regenerative braking and rest periods of driving.
