Road freight is under pressure like never before.
Fuel costs are volatile, squeezing margins on every kilometer. Regulators and customers demand deep cuts in emissions, yet electric trucks remain expensive, scarce, and complex to integrate. Meanwhile, millions of trailers on the road today contribute nothing to efficiency. They are dead weight in a system that desperately needs smarter solutions.
Complete trailer electrification drop‑in solution
In-wheel Propulsion
Compact, efficient, and powerful. Our in-wheel technology delivers instant power and torque and precise control directly at the wheels, enabling smarter, cleaner, and more adaptable trailer movement, without the need for complex drivetrains.
High-capacity Battery
Built for endurance and efficiency. The high-capacity battery system ensures reliable power delivery and extended range, optimized for heavy-duty performance and fast integration into existing platforms.
Intelligent control
At the core of every Cova Power system is advanced control intelligence. Seamlessly managing propulsion, energy, and communication, it ensures the entire trailer system operates safely, efficiently, and intelligently.
Savings that pay for themselves.
In Nordic duty cycles, each Smart Trailer can save up to €30,000 per year in fuel. Payback arrives within the first year of operation, while continuing to generate cost and emission reductions for the lifetime of the trailer.
