Finnish Kempower Demonstrates 1.2 MW Megawatt Charging System in Sweden’s Cold Weather

• February 18, 2026

In a significant demonstration of electric vehicle charging technology, Finnish company Kempower recently showcased its 1.2 megawatt (MW) Megawatt Charging System (MCS) for heavy electric trucks during a winter event in Norrköping, Sweden. The event, known as MCS Live Winter Days, highlighted how high-power EV charging infrastructure performs in cold weather conditions.

Proving High-Power Charging Can Withstand Winter Weather

As the adoption of electric trucks grows, concerns remain about how subzero temperatures could affect their charging capabilities and operational efficiency, particularly in colder climates such as Scandinavia. Low temperatures have often been viewed as a barrier to widespread electric heavy vehicle use, causing hesitation among freight operators about feasibility in winter months.

Addressing this challenge head-on, Kempower conducted the demonstration in January 2026 to show that the powerful 1.2 MW charging system remains fully functional despite freezing conditions. This represents an important step in assuaging industry concerns regarding cold weather’s impact on high-capacity electric vehicle recharging.

The MCS standard, developed to enable rapid charging for heavy-duty vehicles, supports voltage and current levels far beyond typical passenger EV chargers, enabling quicker turnaround times for electric trucks. Kempower’s demonstration at the event showcased its ability to deliver sustained megawatt-level charge even when ambient temperatures are low.

The event proved that winter temperatures do not necessarily diminish the performance and reliability of next-generation EV charging technologies targeted at heavy transport. This is critical for fleets and operators planning to transition to electric trucks in regions where harsh winters are common.

While detailed technical data and commercial availability were not disclosed, the demonstration signals forward momentum in developing robust, climate-resilient charging infrastructure capable of meeting the rigorous demands of electrified freight transport.

With heavy trucking being a major contributor to transportation emissions worldwide, advancements in dependable, high-power charging solutions like Kempower’s 1.2 MW MCS are key to supporting sustainable logistics networks. Reliable operation in cold weather further extends the practical usability of electric trucks, making them a more viable alternative for freight companies operating across diverse environments.

The MCS Live Winter Days event marks another milestone for the maturation of charging technology, reinforcing that powerful electric vehicle charging can overcome environmental challenges and accelerate the shift toward electrified commercial transport.
