Introduction

Trucks and tractor trailers are significant contributors to carbon emissions in the United States. The idea of converting these vehicles to electric is often proposed as a solution to reduce environmental impact. However, this transition comes with numerous challenges. In this article, we will explore the feasibility of converting tractor trailers to electric trucks, delving into the practicality of such a conversion and addressing common misconceptions.

Challenges of Converting Tractor Trailers to Electric

1. Air Emissions and Safety Concerns:

Some argue that the air coming from modern truck exhaust is cleaner than city air. While this may be true, the emissions from these vehicles contribute significantly to pollution. Moreover, the heat generated by the exhaust can be harmful to drivers and passengers. Converting to electric trucks can help mitigate these issues, providing cleaner air and safer conditions on the road.

2. Availability of Charging Infrastructure:

One of the most significant challenges is the availability of charging infrastructure for heavy-duty electric vehicles (EVs). Comparing this requirement to the Tesla charging network, it is evident that there is a significant gap in infrastructure. The Tesla Supercharger network is well-established in many areas, but the commercial charging network for tractor trailers is far from developed.

3. Range Anxiety:

Electric power, while promising, is not yet practical for large highway trucks. To address this, a balance must be found between range and charging frequency. As Rick Klugman points out, a range of 600 miles per day is what is actually needed, with one mandatory stop of 30 minutes to recharge. For the average trucking route, a range of 400 miles is a safer approach with an additional stop of 30 minutes to charge the remaining 200 miles.

Feasibility of the Conversion

Technological Solutions:

The technological landscape is rapidly changing, and scientists worldwide are working on viable solutions for heavy-duty electric vehicles. While transitioning to electric trucks is still a challenge, it is becoming increasingly feasible. Proper battery design and fast-charging technology are crucial. For instance, a battery of 750 kWh to 800 kWh with the capability to charge at a top speed of about 1 MW could meet the demands of long-haul transportation.

Economic Impact:

Converting trucks and tractor trailers to electric does not just benefit the environment; it can also improve economic efficiency. Electric motors offer a high torque output, vital for heavy-duty vehicles. With the right range and charging infrastructure, electric trucks can offer several benefits, including lower operational costs and reduced downtime for drivers.

Infrastructure Development:

The development of charging infrastructure is critical. Governments and private entities must invest in building charging stations along major highways and in rest stops. This infrastructure could help mitigate range anxiety and provide drivers with the peace of mind needed to embrace electric trucks.

Conclusion

While there are challenges in converting trucks and tractor trailers to electric, the potential benefits make this a worthwhile endeavor. Technological advancements, paired with strategic investments in infrastructure, can help address the issues currently hindering the widespread adoption of electric trucks. As the industry evolves, the transition to electric trucks is inevitable, offering a cleaner, more efficient future for long-haul transportation.
