Hevtec Koski MCS Charging Interface

/ˈkos.ki/ — KOSS-kee

Megawatt charging is coming, but integrating MCS (Megawatt Charging System) into a real machine is still a challenge. KOSKI solves this by providing a rugged, integration ready MCS interface designed for heavy duty environments and practical machine architecture.

Heavy-Duty MCS Interface Status & Readiness

The first A-series MCS charging interface piloting will start in early 2026 in a heavy duty truck in Finland.

Why KOSKI for Heavy-Duty MCS Charging

Designed for interoperability: KOSKI follows the direction of global MCS standardization for heavy-duty charging.

Rugged by design: IP66 and wide operating temperature range for harsh environments.

Integration-ready: straightforward installation with PowerLok connection.

Clear ratings, no guessing: 1000 Vdc system voltage and high current capability defined up front.

What is MCS and why does it matter?

MCS (Megawatt Charging System) is an emerging megawatt-class DC charging system for heavy-duty applications, designed for interoperability with modern communication and safety requirements.

Why talk about MCS now, isn’t it still emerging?

Yes. Even major suppliers state that MCS vehicle charging inlets are still being developed, so starting system-level integration work early reduces program risk and shortens time-to-field.

When is MCS an especially strong solution?

You need very fast DC charging because energy demand is high.
Downtime must stay short, so utilization stays high.
Charging happens at a few realistic hubs, improving TCO and reducing risk.

Typical applications: long-haul and regional heavy-duty trucks, ports and terminal logistics, mining and quarry operations, high-utilization construction fleets, and industrial sites with centralized charging hubs.

Hevtec designs charging as part of the full electric powertrain system, helping OEMs reduce integration effort and de-risk field deployment.
