Hyundai and Kia turn up EV efficiency with new heat pump technology

Hyundai Motor Company and Kia Motors Corporation have revealed new details of an innovative heat pump system, deployed in Hyundai and Kia’s global electric vehicle (EV) line-up, to maximise their all-electric driving range in low temperatures.

The heat pump maximises the distance that Hyundai and Kia EVs can travel on a single charge, scavenging waste heat to warm the cabin. It enables EV drivers to heat their car’s cabin in cold weather without significantly impacting electric driving range.

The technology was first introduced in 2014 on the first-generation Kia Soul EV. Comprising a compressor, evaporator and condenser, the heat pump captured waste heat given off by the vehicle’s electrical components, recycling this energy to heat the cabin more efficiently. The technology meant the Soul EV’s 180km electric range was protected in cold weather driving conditions.

The new system scavenges waste heat from an increased number of sources for optimum cold-weather EV range and the companies say these innovations mean that Hyundai and Kia EVs offer more consistent range in temperatures where other EVs start to see a significant decline in the distance possible from a single charge.
