Joint Initiative for EV Conversion Trucks

On January 15, 2026, JA Mitsui Lease Group, which includes JA Mitsui Lease Co., Ltd. and JA Mitsui Lease Auto Co., Ltd., has entered into a collaborative demonstration project with Denchi Co., Ltd. and Yamato Mobility & Mfg. in the pursuit of advancing the trustworthiness of Electric Vehicles (EV) conversion trucks through enhanced battery diagnostics.

Understanding EV Conversion Trucks

EV conversion trucks are created by transforming diesel-powered vehicles into electric ones by removing combustion components and installing electric motors and batteries. This approach has gained attention within the logistics industry as a cost-effective solution toward decarbonization, allowing companies to convert existing trucks at a fraction of the cost of purchasing new electric models.

Addressing Key Challenges

As the logistics sector accelerates its shift to EVs, the transition of diesel trucks to electric vehicles has emerged as a focal point. However, many potential adopters express serious concerns regarding battery deterioration, which may lead to reduced driving ranges and risks of running out of power. Their primary anxieties lie in understanding the current state and longevity of the batteries onboard these trucks.

This demonstration project aims to directly tackle these concerns by integrating Denchi's patented high-precision battery diagnostic technology with Yamato's conversion techniques. The goal is to establish an objective method for assessing the battery's degradation and overall health, known as State of Health (SOH).

Collaborative Roles of Participating Companies

The roles of the involved companies are clearly defined for successful execution of the project:

• - JA Mitsui Lease Auto: Providing expertise in EV leasing and used vehicle markets.
• - Denchi: Conducting detailed assessments and analytics of battery states using proprietary diagnostic technologies.
• - Yamato Mobility & Mfg.: Offering the demonstration vehicles and operational data while providing feedback based on results.

Perspectives from the Partners

Each partner has emphasized the importance of this initiative:

• - JA Mitsui Lease Auto highlights that Denchi's diagnostic technology is key to enhancing the value of EV batteries, ultimately aiding the circular economy. They see this initiative as a way to resolve the issues surrounding the used EV conversion truck market.
• - Denchi expressed pride in collaborating with Yamato Mobility & Mfg. They aim to use their cutting-edge diagnostic technology to ensure the long-term health of EV batteries and dispel customer anxieties regarding the durability of converted trucks.
• - Yamato Mobility & Mfg. noted that while their trucks ensure high quality with new batteries, lingering doubts about long-term EV reliability remain significant. Through Denchi’s diagnostics in after-sales service, they aim to provide objective evidence of battery health, ensuring customer confidence in a sustainable environment.

Conclusion

The collective efforts of these companies are poised to not only bolster the market for EV conversion trucks but also hasten the overall transition to greener logistics. As the project unfolds, it sets a precedent for transparency and reliability in the EV conversion sector, encouraging wider acceptance and implementation of sustainable transport solutions.
