Sweden unveiled a 1.2 MW electric vehicle charger—and the cold didn’t stop it.

MCS Live Winter Days: testing megawatt chargers in Swedish Norrköping

In January 2026, the Finnish company Kempower held an event *MCS Live Winter Days* in the city of Norrköping (Sweden). The goal was to demonstrate that high‑power charging for heavy electric trucks works even at low temperatures.

1. Participants and venue
Company Product Feature
MAN Truck & Buse TGX battery 480 kWh, range ≈ 500 km
Scania – Volvo –

Tests were conducted at the *Alfredsson Transport AB* truck park, which has used only electric vehicles since 2015 and became Sweden’s first megawatt charging site. The facility hosts 12 stations, each capable of delivering up to 1.2 MW.

2. Megawatt Charging System (MCS) technology
* Power: 1–1.2 MW

* Charge class: liquid cooling

* Protocol: standard for megawatt systems

Practical example – MAN eTGX.

When charging at 750 kW, the range increases by about 350 km in 45 minutes.

3. Test results
* The system operated stably at negative temperatures.

* Reliable communication between truck and charger was maintained.

* Performance was monitored with minimal efficiency loss.

Participants noted full integration of hardware and software and no critical issues even in cold weather.

4. Additional resources on site
* Batteries with a capacity of 2.4 MWh

* Solar panels with a power output of 400 kW

These elements allow:

1. Optimizing electricity costs.

2. Mitigating peak load when simultaneously charging 2–3 trucks at 1.2 MW each, without overloading the city grid (only 2.4 MW).

5. Importance for the future
The demonstration showed that MCS technology is ready for real commercial deployment. If electric trucks become mainstream, power grids will need development – this should already be discussed with authorities.

*Next step:* a series of trials after the first public demonstration in August 2025 (Scania + Kempower).
