Hyundai and Kia improve the thermal management of the EV batteries they use

9 June 2020, 12:09:23

Hyundai and Kia improve the thermal management of the EV batteries they useHyundai and Kia have announced that their heat pump technology for EV batteries has been improved. This technology was introduced in 2014 for the Kia Soul EV and this its first major improvement. The main change is that the system now gathers excess heat not only from power electrics (PE) modules (such as drive motors, on-board chargers, and inverters), but also from the battery pack and slow charger. The system uses the heat generated by these components to vaporize refrigerant from liquid to gas form. High-pressure gas is discharged from the compressor and forced into a condenser to be converted back into a liquid. This process generates additional heat energy that is recovered by the heat pump and used to warm the cabin.

This captured energy improves the efficiency of the HVAC (heating, ventilation and air conditioning) system, recycling it to more efficiently heat up the cabin and minimize battery power consumption. By reducing the load on the battery, the heat pump cuts energy consumption from the HVAC system, maximizing the available electric driving range of the car. As a result, Hyundai and Kia EVs offer a more consistent range in temperatures where other EVs start to see a significant decline in the distance possible from a single charge.

The Norwegian Automotive Federation (NAF) recently compared 20 EVs in cold and warm weather conditions to identify models with the most consistent driving range and charging performance. The test monitored the performance deviation of each vehicle in cold conditions compared to quoted manufacturer figures. The Kona Electric took first place, travelling 405km in the cold - compared to the 449km quoted under WLTP combined cycle testing conditions (23°C / 73°F). In severe cold weather, the Kona Electric offered 91 percent of its WLTP combined cycle range, deviating just 9 percent from its claimed all-electric driving range.

A water-cooling system for Hyundai and Kia’s EV battery packs, rather than conventional air cooling, have yielded further increases in range without increasing physical dimensions. This development means battery cells in Hyundai and Kia EVs can be packaged much more tightly, with water-cooling channels taking up less space than air-cooling channels, increasing battery density by up to 35%. This innovation means the latest EVs from Hyundai and Kia offer around twice as much driving range and battery capacity compared to the their first-generation EVs - and are capable of travelling significantly further on a single charge.
