hnical and economic analyses, the report evaluated the feasibility of
implementing E-CVT transmissions in the electric vehicle market.
• Based on technical and economic analyses, the report evaluated the feasibility of
implementing E-CVT transmissions in the electric vehicle market.
5.2. Recommendation
Based on the results of the research and analyses, the group has proposed several
recommendations to guide and promote the development and application of E-CVT
transmissions in the hybrid and battery electric vehicle (BEV) sectors in the future:
- Further research on the Compound Split-Compound Coupled E-CVT system,
focusing on its structure and how mechanical systems coordinate and operate.
- Conduct in-depth studies on the E-CVT transmissions of Ford and GM to
compare them with Toyota’s E-CVT (the first model of electronic continuously variable
transmission) as discussed in the report.
- Research and apply E-CVT systems to electric vehicles using simulation software
based on the configurations and specifications from the project to design an E-CVT
transmission suitable for integration into electric vehicles.

- Explore advancements in materials and designs for E-CVT systems, such as
using materials like carbon fiber or aluminum alloys to reduce the system’s weight,
thereby increasing energy efficiency. Additionally, improve gear and internal
mechanism designs to reduce mechanical losses and enhance the durability of E-CVT
transmissions.
5.3. Conclusion
The research project on E-CVT transmissions for hybrid vehicles and their
potential application in electric vehicles has provided significant knowledge and offered
a comprehensive, scientific, and practical perspective on E-CVT systems. Identifying
and addressing technical challenges and resource limitations have made this project a
valuable learning journey. The analyses and recommendations in the report not only help
readers gain a deeper understanding of E-CVT technology but also open new directions
for applying this transmission system to electric vehicles in the future.
The conclusions and proposals in the report affirm the immense potential of E-CVT
transmissions in driving the development of the hybrid and electric vehicle market,
contributing to a more sustainable and efficient transportation industry. Lastly, through
this graduation project, our team hopes it can serve as a reference document for readers
interested in learning about and researching E-CVT systems.
