Corporate Fleet Electrification: Driving the Transition from Diesel to Electric

As businesses around the world look for ways to reduce operating costs, improve fleet efficiency, and meet increasingly strict environmental requirements, corporate fleet electrification is becoming an important part of modern fleet management.

For many companies, however, replacing an entire diesel fleet with brand-new electric vehicles is not always the most practical or economical solution. Existing vehicles may still have years of useful life, while the chassis, body, transmission, and working equipment may already be perfectly suited to their applications.

This is where diesel-to-electric vehicle conversion provides an alternative.

By replacing the conventional diesel powertrain with a properly engineered electric drive system, companies can extend the service life of existing vehicles while moving toward a cleaner and more efficient fleet.

Green Motor Tech provides scalable electric powertrain solutions based on 96V and 144V platforms, including high-torque PMSM motors, motor controllers, VCU systems, and liquid-cooled drive solutions for different fleet applications.

Why Electrify a Corporate Fleet?

Corporate fleets include much more than passenger cars. Delivery vans, utility vehicles, pickup trucks, service vehicles, airport vehicles, industrial transport vehicles, agricultural vehicles, and light commercial trucks can all benefit from electrification.

Compared with conventional diesel powertrains, electric drive systems offer several important advantages.

Lower operating costs are one of the main reasons companies consider fleet electrification. Electric motors are highly efficient and have fewer mechanical components requiring routine maintenance. There is no engine oil, fuel injection system, exhaust system, or conventional engine maintenance schedule.

Electric vehicles also provide instant torque from low speed, which is especially valuable for commercial vehicles that frequently start, stop, carry loads, climb ramps, or operate at low speeds.

For companies operating vehicles in urban areas, factories, warehouses, campuses, ports, airports, and industrial parks, the reduction in engine noise and tailpipe emissions can also create a better working environment.

96V Electric Drive Systems for Light Commercial Fleets

Our 96V electric drive platform is designed for compact and light-duty fleet vehicles where efficiency, packaging, cost, and reliability are important.

Typical applications include:

• Small commercial vehicles
• Utility vehicles
• Delivery vehicles
• Light trucks
• Campus vehicles
• Industrial transport vehicles
• Agricultural vehicles
• Special-purpose vehicles

We offer both 96V 15kW and 96V 20kW configurations.

The 15kW system is suitable for lighter vehicles and relatively moderate operating conditions, while the 20kW system provides additional power and torque for vehicles with higher payloads or more demanding duty cycles.

The system can be matched to the vehicle according to its total weight, target speed, tire size, differential ratio, transmission configuration, gradeability, and daily operating distance.

This makes the 96V platform a practical starting point for companies looking to electrify smaller vehicles within their existing fleet.

144V Systems for Higher Performance Requirements

When vehicle weight, payload, speed, or continuous operating load increases, a higher-voltage platform can provide additional performance and efficiency advantages.

Our 144V electric drive systems include 144V 25kW and 144V 40kW configurations, designed for medium-duty and higher-performance vehicle conversion projects.

Typical applications include:

• Pickup trucks
• Medium-duty commercial vehicles
• Utility trucks
• Agricultural vehicles
• Industrial vehicles
• Service vehicles
• Special-purpose vehicles

Moving from a lower-voltage architecture to 144V also helps reduce the current required for a given power level. Lower current can help reduce electrical losses and thermal stress in cables, connectors, busbars, and other high-current components.

For fleet vehicles that operate for long hours or under significant loads, this can be an important consideration when designing the complete electric powertrain.

High-Torque PMSM Motors for Commercial Vehicles

Power rating alone does not determine how an electric vehicle performs.

For commercial fleet applications, torque is equally important.

Our electric drive systems can be equipped with Permanent Magnet Synchronous Motors (PMSM) designed to provide high efficiency and strong low-speed torque.

One of our high-torque configurations can deliver up to 252 N·m of motor torque, providing strong initial acceleration and pulling capability.

This characteristic is particularly useful for commercial vehicles that:

• Carry heavy payloads
• Frequently start and stop
• Operate on ramps or inclines
• Require strong low-speed acceleration
• Work in industrial environments
• Need stable performance under changing loads

The electric motor can also work together with the original vehicle transmission or a customized reduction system, depending on the vehicle design and performance requirements.

This gives fleet operators greater flexibility when converting existing diesel vehicles rather than completely redesigning the vehicle.

Liquid Cooling for Continuous Fleet Operation

Fleet vehicles often operate much longer and harder than private passenger vehicles.

A vehicle used for commercial service may run for many hours every day, making thermal management a critical part of electric powertrain design.

For higher-power applications, our electric drive solutions can incorporate liquid-cooled motors and controllers.

Liquid cooling provides more effective heat transfer than air cooling and helps maintain stable operating temperatures during continuous high-load operation.

This is particularly valuable for:

• Heavy-load applications
• Long operating cycles
• Frequent acceleration
• High ambient temperatures
• Climbing conditions
• High-power commercial vehicles

Our liquid-cooled drive systems can be engineered around the actual vehicle duty cycle, ensuring that the motor, controller, cables, and other high-current components are considered as one complete system.

More Than a Motor: A Complete Electric Powertrain

Successful fleet electrification requires more than simply installing an electric motor.

Green Motor Tech can provide an integrated electric drive solution including:

PMSM Motor + Motor Controller + VCU + DC-DC Converter + Battery System + BMS + On-Board Charger + Display + Wiring Harness

The controller manages motor operation and torque delivery, while the VCU coordinates the electric powertrain with the vehicle’s accelerator, brake system, dashboard, safety functions, and other vehicle signals.

Battery capacity can then be selected according to the vehicle’s daily mileage and actual energy consumption rather than simply choosing a battery based on nominal capacity.

This system-level approach is important when converting multiple vehicles of the same model into a standardized corporate fleet.

From One Converted Vehicle to Fleet Electrification

Corporate fleet electrification does not need to happen overnight.

A practical approach is to begin with one or several pilot vehicles.

First, the original diesel vehicle is evaluated based on:

• Vehicle weight and payload
• Maximum and average speed
• Daily mileage
• Driving cycle
• Gradeability
• Differential ratio
• Tire size
• Transmission
• Available battery space
• Auxiliary electrical loads
• Ambient operating conditions

Based on these parameters, the appropriate electric powertrain can be selected.

For example:

96V 15kW – Light-duty and compact commercial vehicles

96V 20kW – Light commercial and utility vehicles

144V 25kW – Medium-duty and higher-load applications

144V 40kW – Larger commercial and demanding fleet applications

After the pilot vehicles are tested and validated, the same technical configuration can be standardized for additional vehicles.

This creates a scalable path from diesel vehicle conversion to full corporate fleet electrification.

The Future of Corporate Fleet Electrification

For many businesses, the question is no longer whether fleet electrification will happen, but how to make the transition economically and technically practical.

Diesel-to-electric conversion provides an opportunity to reuse existing vehicle assets while introducing modern electric powertrain technology.

With 96V and 144V electric drive systems, high-torque PMSM motors, up to 252 N·m of motor torque, and liquid-cooling technology, Green Motor Tech supports fleet operators looking for reliable solutions for commercial and industrial vehicle electrification.

The goal is not simply to replace a diesel engine.

It is to build an electric powertrain that matches the vehicle, the workload, and the real operating conditions of the fleet.

Start with one vehicle. Validate the technology. Standardize the solution. Then electrify the fleet.

If your company is considering corporate fleet electrification or diesel-to-electric conversion, Green Motor Tech can evaluate your existing vehicle and recommend a suitable 96V or 144V electric drive system.
