When people hear “electric truck,” they often picture a battery-only vehicle that must be plugged in to recharge. Edison Motors is pursuing a different approach for some of Canada’s toughest truck jobs: diesel-electric trucks designed for logging, heavy haul and other work where steep grades, heavy loads and limited charging access are part of the day.
The British Columbia company is developing trucks that use electric drive while carrying an onboard diesel generator. The concept borrows from a familiar idea in rail: use a diesel engine to generate electricity, then use electric motors to move the vehicle. Edison’s challenge is to make that arrangement work in a road truck that can haul logs, climb remote roads, operate through Canadian weather and be serviced by the people who depend on it.
It is an ambitious example of Canadian innovation. It is also still an emerging truck programme, so its fuel savings, durability and long-term ownership costs need to be judged by real work and measured results.
What is Edison Motors?
Edison Motors is a privately owned Canadian company now based in Donald, near Golden, British Columbia. The company says its work grew out of the experience of truckers and loggers looking for a way to combine electric drive with the range and refuelling convenience of diesel. Its early proof-of-concept truck, Carl, was built from a 1962 Kenworth LW 924. Edison says Carl used a Caterpillar 3306 diesel as a generator and a Tesla Model S electric motor.
The company’s current focus is the BDE-Series, a vocational truck designed for logging, heavy haul and other demanding applications. Edison says it is developing trucks and powertrains as well as its own chassis and cab. Its published lineup also includes a conventional mechanical version of the BDE, alongside diesel-electric configurations.
How does a diesel-electric logging truck work?
In a conventional diesel truck, the engine produces mechanical power that passes through the transmission, driveshafts and differentials to the wheels.
In a diesel-electric series arrangement, the diesel engine’s main job is different. It drives a generator. Electricity from the generator and battery system powers electric motors at the drive axles.
That changes how power reaches the ground:
- The diesel engine runs the generator.
- The generator supplies electricity to the truck’s electrical system.
- Batteries store energy and can provide extra power when demand rises.
- Electric drive motors turn the wheels.
- During suitable braking and downhill operation, the drive system can recover some energy and send it back to the batteries.
Edison describes its approach as a diesel-electric system in which the truck can operate electrically while the generator recharges the batteries. The system’s attraction for logging is that a truck can have electric drive without relying on public charging stations throughout a remote workday.
That does not mean the truck is a battery-only electric vehicle. It still burns diesel when its generator is running. The potential benefit is using the generator and battery together to meet the job’s changing power demands, while capturing some energy that would otherwise be lost during braking or downhill travel.
Why consider electric drive for logging?
Logging trucks face a demanding mix of operating conditions. A loaded truck may climb steep grades slowly, descend with substantial weight, travel rough roads, stop and start repeatedly, and spend time far from repair facilities or charging infrastructure.
Electric motors can provide strong torque from low vehicle speed. That may be useful when starting on a grade or moving a heavy vehicle at low speed. Regenerative braking may also recover some energy on descents and reduce the amount of work done by friction brakes in conditions where regeneration is available and properly controlled.
Those are technical opportunities, not guaranteed savings. Results depend on the route, the truck’s weight, the load, the amount of climbing and descending, speed, weather, battery state of charge and how the vehicle is operated.
| Conventional mechanical diesel | Edison’s diesel-electric concept |
|---|---|
| Engine power passes through a mechanical transmission and driveline to the axles. | Diesel engine drives a generator; electric motors provide drive at the axles. |
| Transmission gear selection and engine speed are central to delivering power. | Electric motors provide the wheel torque; the generator and batteries supply electrical power. |
| Braking energy is generally dissipated as heat in the brakes. | Some braking energy may be recovered through regenerative braking, depending on conditions and system limits. |
| Refuelling is straightforward, and service practices are familiar to many fleets. | Diesel refuelling remains available, but the truck adds high-voltage components, batteries, power electronics and electric drive axles that require appropriate service knowledge. |
What has Edison announced about its trucks?
Edison’s BDE-Series specification page lists a diesel-electric configuration with a Scania diesel generator rated up to 500 kW, a 110-kWh battery, a 740-volt system and electric axles. The company lists up to 2,400 horsepower peak power and 1,600 horsepower continuous power for its tri-drive configuration. It also lists a separate mechanical BDE configuration using a 605-horsepower Cummins X15 and an Eaton 18-speed transmission. These are company-published specifications; they should be confirmed against the exact truck configuration being evaluated.
The difference between peak and continuous power matters. Peak output is not the same as power the truck can sustain indefinitely. Battery output, generator capacity, cooling, operating conditions and the selected axle configuration all affect what a particular truck can deliver over time.
Edison’s prototype history includes Topsy, which the company describes as its first production prototype. Its published information says Topsy uses a 280-kWh battery, a Caterpillar C9 diesel generator rated at 500 kW and electric axles. The specifications on the BDE page differ from Topsy’s prototype details, which is a reminder that the company has been developing and revising configurations. A fleet should compare the proposed build sheet with the tested vehicle, rather than assuming every truck has the same hardware.
The company announced in May 2026 that it had received Environment and Climate Change Canada approval to manufacture Class 8 diesel-electric hybrid vehicles in Canada. Edison’s announcement said it had delivered one Class 8 prototype and one Class 5 conversion to demonstration partners, and expected to deliver more vehicles during 2026. Those are company-reported milestones, not evidence of large-scale production or long-term fleet performance.
Edison also announced the grand opening of its Donald factory in June 2026. Opening a facility is an important step for a manufacturer, but production capacity, build consistency, parts supply and customer support will be demonstrated over time as vehicles are completed and put to work.
Approval is a milestone, not the end of certification
Vehicle manufacturing involves more than one regulatory requirement. Environment and Climate Change Canada administers emissions requirements, while Transport Canada oversees federal motor vehicle safety requirements. Transport Canada says Canadian-built vehicles destined for the Canadian market must comply with the Canada Motor Vehicle Safety Standards, and manufacturers need authorization to apply the National Safety Mark to prescribed classes of vehicles.
ECCC’s heavy-duty vehicle guidance explains that emissions rules apply to on-road heavy-duty vehicles and engines, including vocational trucks, and sets out requirements around emissions conformity and the National Emissions Mark.
For a buyer, the practical question is what documentation and certification apply to the specific chassis, model year, powertrain and intended use being ordered. An emissions approval milestone should not be taken as proof that every vehicle configuration has completed every safety, registration or customer-specific approval step.
What fuel savings might be possible?
Edison promotes fuel savings as a reason to consider its trucks. Its website gives different savings ranges for different applications and says the greatest opportunities are in vocational work with frequent starts, stops and steep terrain. Those figures are the company’s claims; they are not a substitute for independently verified field data.
A fair comparison would record more than fuel consumed over a short demonstration. Fleets would want comparable data on:
- Litres of diesel per tonne-kilometre or per load moved
- Route, grade, load, weather and idle time
- Battery state of charge at the beginning and end of each shift
- Generator operating hours and fuel use
- Brake wear and maintenance intervals
- Downtime, parts availability and repair costs
- Purchase price, financing, warranty coverage and resale value
A logging truck that repeatedly climbs and descends steep roads may have a different result from one spending most of its time on flatter highways. The truck’s duty cycle has to match the technology for the numbers to mean anything.
The serviceability question
A new drivetrain needs a service plan that works outside a factory. Edison says it aims to use common, off-the-shelf components where possible and emphasizes repairability. That is a useful goal, especially for operators working far from major service centres.
The real test will be how the complete system holds up: electric axles, high-voltage cabling, power electronics, batteries, cooling systems, generator controls and the vehicle’s integration with the chassis and body equipment. Fleets will also need clear diagnostic procedures, parts support, technician training, warranty terms and a plan for safe high-voltage work.
For mechanics, the change is not simply “replace the transmission with motors.” It shifts some troubleshooting toward electrical generation, battery management, inverter and motor controls, thermal management and high-voltage safety—while retaining a diesel engine and its associated systems.
A Canadian innovation worth watching
Edison Motors is trying to address a real challenge: how to electrify demanding vocational trucks when battery-only operation and charging infrastructure may not fit every remote job. Its diesel-electric approach is an attempt to adapt electric drive to the operating realities of logging and heavy haul.
The Canadian innovation is not just the use of electric motors. It is the effort to develop a truck around Canadian resource-sector work, build and test it in British Columbia, and create a product that can operate where the work is done. The company has also used its annual electric go-kart challenge to bring students and community teams into hands-on vehicle design and engineering.
There is still a gap between a promising prototype and a dependable production truck. Edison will need to show how its vehicles perform across seasons, terrain and payloads—and whether the operating savings outweigh the purchase price, maintenance and training costs.
That is why the most useful next chapter will be the customer experience: logged fuel data, uptime records, maintenance history and performance over full work seasons. If those results support the company’s claims, Edison could become a notable Canadian example of practical innovation in heavy trucking.
For now, it is a promising development to watch—not a proven replacement for every conventional logging truck.
