Main 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. In a paper in the Journal of Power Sources , they report that this technique fully restores room-temperature battery power and regeneration in 13, 33, 46, 56 and 112 seconds into uninterrupted driving in 0, −10, −20, −30 and −40 °C environments, respectively. Correspondingly, the strategy significantly increases cruise range of a vehicle operated at cold temperatures—49% at −40 °C in simulated US06 driving cycle tests. Based on their findings, the team suggests that smart batteries with embedded sensing/actuation […]
