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

Green Car Congress

Covered by 11 patents and four publications, the development of Ultium energy recovery traces its inception back to GM’s first EV, the EV1, in the late 1990s, when GM engineers first developed an EV heat pump. EV batteries, power electronics and other propulsion components produce heat.

GM develops prototype two-mode hybrid transmission with enhanced EV capability for plug-in hybrids

Green Car Congress

With this, there are two new electric-only modes: EV1 and EV2. In EV1, the transmission is in the first continuously-variable mode EVT1 with both brake-clutch CB12R and CB5 applied. Overall, EV1 has a higher output torque capability, with better efficiency in the lower speed, higher torque region. —Yang et al.
