The Hyundai Kona's Thermal Management System Keeps its Battery Pack From Overheating

Long charging intervals have been plaguing adoption of electric vehicles. To tackle this problem, carmakers like electric truck maker Rivian are developing fast charging and thermal management technologies for EV battery packs at an increasingly faster pace. 

Korean car manufacturer Hyundai is also joining the bandwagon and has developed a dedicated thermal management system, which takes on the duties of preventing overheating of Kona's battery pack in its American variants.

In October, Hyundai announced that it will be bringing the Kona electric SUV to North America. The Korean manufacturer has now announced that the upcoming electric SUV will not get the active battery heating feature. Unlike the Hyundai Kona's delivered to Europe, the North American models will not have the ability to cool and warm the batteries as required. 

Some reports speculated that the American versions of Hyundai Kona would get active heating, however these claims were disproved. Several reviews were on point and mentioned on numerous occasions that the Kona models slated to hit the U.S. market would not have a battery warming feature. 

Instead, the company will offer a comparatively ineffective 5.5 kW resistive cabin heating system. Unlike American car buyers, Canadians living in colder climates will be able to buy their Kona's with a more advanced heat pump system, which will take on the duties of heating the passenger compartment as well as the EVs batteries. 

The U.S. version of Kona will have the ability to harness the heat generated from the electric motor powertrain electronics and use it to supply heat to the battery packs when the electric vehicle is being operating in cold conditions, even with the lack of a dedicated battery heater.

The Hyundai Kona

A case can be made the Hyundai took this decision on a solely on a cost-cutting basis. The automaker wants to introduce Kona electric into the American market with a competitive price tag. 

Hyundai has announced that it will introduce Kona electric with a starting price of $36,450 and with the federal tax credit for new electric vehicles, that price tag drops down to around $30,000. Hyundai has also announced that Kona electric will only be offered in the ten ZEV states in the U.S. Out of all the Kona Evs which sold in North America, Hyundai believes that it will sell a large chunk of the electric crossover in the state of California—the biggest market for electric vehicles in the U.S.
