Tesla (TSLA) recently began mass production of its electric truck "Semi." Beyond being an eco-friendly mode of transport, it is already being hailed as a game changer that could shake up the freight industry. 800km Range: Crossing the Critical Threshold for Electric Trucks The core of the newly mass-produced Tesla Semi is its overwhelming driving performance. The Long Range model can travel approximately 500 miles (800km) on a single charge. Until now, the industry has broadly pointed out that short driving ranges made long-haul freight impossible with electric trucks. But the Semi has broken through this limit with its battery performance. Tesla's next-generation battery technology, the "4680 battery," has been applied. The 4680 battery is a large cylindrical cell measuring 46mm in diameter and 80mm in height, featuring significantly improved energy density compared to existing batteries. Tesla previously announced in 2023 that it would invest $3.6 billion (approximately 5.34 trillion won) to expand its Nevada plant and secure production facilities for the Semi truck and 4680 batteries. Additionally, the battery is designed to last for 1 million miles (approximately 1.6 million km) of driving. This means the truck can operate throughout its entire life cycle without battery replacement. It is expected to dramatically lower maintenance costs, a sensitive issue for truck owners. The industry is paying particular attention to the driving range. 800km covers a significant portion of freight routes within the United States, and in Korean terms, it is equivalent to a round trip between Seoul and Busan. In other words, it has crossed the technical threshold. The Semi is a truck only in appearance, with Tesla's cutting-edge technology applied throughout its interior. First, a 48V architecture has been introduced. Compared to the existing 12V system, it maximizes power efficiency to stably supply energy to various electronic devices in
