寒冬也不怕續航力流失，HYUNDAI與KIA發表電動熱泵新技術

2014年，KIA首次推出Soul電動車款，而從當時開始，便與HYUNDAI聯合在電動車上面導入了「熱泵」技術；近幾年來，品牌也仍在改進這個技術，讓電動車在效能運用方面能夠更不浪費能源，而近日，挪威汽車聯合會（NAF；Norwegian Automobile Federation）也在Kona Electric電動車上面進行冬季測試，證明這個新技術的優點。
能夠實現新型熱泵技術的高效率特點，主要就是因為可從各項零組件當中收集廢熱，也就是多餘的、隨著引擎與馬達運轉時所產生的熱能；兩家車廠也表示，第一個熱泵將從電動模組部分獲取熱源，這部分就包括了電動馬達、逆變器、以及車載充電器；另外，電池組以及基本的充電裝置也都是熱能來源，廣泛來說，只要會牽涉到熱能的組件都包含在內；同時，車廠工程師則通過電動原型車來進行低溫測試，並設法進一步改良這個技術，而車廠也表示，除了能夠證明熱泵的效率高，電池能量密度更將能夠提高35%。
最後，韓國環境部也做了一項相關研究，指出HYUNDAI Kona Electric及KIA Niro兩台電動車款在零下7度C的溫度下，替車款保留了高達90%的續航力，在寒冷情況之下進行相同測試時，其他沒有搭載熱泵技術的電動車，續航力跌幅則從18%到高達43%的都有。
