What is D2E repowering?
Diesel-to-Electric (D2E) repowering converts an existing diesel truck into a full battery electric vehicle (BEV) by:
- Removing the internal combustion engine (ICE), fuel system, exhaust system, and transmission
- Replacing them with a fully electric drivetrain, battery packs, and an electric motor
This transformation allows fleets to transition to clean energy while extending the value of their current vehicles.
Repowering: A New Life for Your Truck
Repowering transforms a diesel truck into a fully electric vehicle, delivering:
- Higher energy efficiency
- Zero emissions
- Lower maintenance costs
- Extended operational life
At the heart of our approach is the circular economy — giving your existing asset a second life instead of replacing it.
The retrofit process upgrades the truck’s systems while preserving key components like the original chassis, axles, cabin, brakes, suspension, and steering — ensuring maximum reliability and sustainability.
Our Mission
"TROVA accelerates the shift to sustainable transportation through diesel-to-electric truck repowering."
"We support a circular economy and renewable energy use, while facilitating an economic efficient logistics industry through cost reduction.”
TROVA's Journey
🚛 Targeted Performance
Repowered for urban and regional routes, these trucks cover up to 450 km/day — right where 50% of freight journeys in Europe take place.
🧰 Empowering the Industry
With “Powered by TROVA” kits, OEMs and independent dealers will be able to electrify fleets — faster, smarter, and at scale.
🚀 Always One Step Ahead
TROVA integrates the latest in Telematics ensuring every truck is future-ready.
🌱 A Major Step Towards Zero Emissions
By electrifying existing fleets, TROVA contributes to a greener planet, helping meet and exceed European Emission Standards.
🧠 Innovation at the Core
Our future Zero Emission Factory will power a circular ecosystem, driving industry change through sustainable and multi-stakeholder collaboration.
⚡ Fast-Tracking Electrification
TROVA accelerates the shift to clean transport by repowering Heavy-Duty (HD) trucks over 16 tons — from Diesel to Full Battery Electric — in just 48 Working hours.
Environmental Regulations
Governments are imposing stricter environmental regulations to reduce air pollution and greenhouse gas emissions. Many cities are implementing Low Emission Zones (LEZ) and plan to ban Diesel vehicles.
Why should you repower your trucks?
Modernisation without full replacement
Retrofit allows companies to upgrade their existing fleet without purchasing entirely new vehicles, which are up to 50% more expensive. New electric trucks have delivery times of 12-18 months.
Corporate Social Responsibility (CSR)
Many companies have sustainability or carbon reduction goals as part of their corporate strategy (ESG). Repowering to electric trucks helps to meet these targets because of its circular economy nature.
Cost savings on fuel
In many cases, the cost of electricity is lower than Diesel, especially when trucks can be charged during off-peak hours. This can lead to significant long-term savings. Diesel prices are also more volatile and subject to global economic and political fluctuations. The regenerative braking contributes to reach a higher efficiency and generate more cost savings.
Access to incentives & subsidies
Many governments offer financial incentives, rebates and tax credits to companies transitioning to electric vehicles. Those incentives are also applicable on repowered trucks.
Reduced maintenance costs
Electric drivetrains have fewer moving parts compared to diesel engines, which translates to lower maintenance requirements. There is no need to change oil, exhaust system repairs, or engine related maintenance that come with a diesel vehicle.
