Project Overview

Society’s recent push to transition to EVs has been very fast-paced. Consequently, most EVs in today’s market are previously-designed IC vehicles that have been adapted to fit necessary EV components.

A new concept designed from the ground up would allow for a more efficient, purposely-designed, lightweight EV (Zigy). The use of extensive aerodynamic analysis coupled with an extreme lightweighting approach would improve the energy efficiency to achieve an extended range. Further targets include ergonomic evaluation, development to capitalise on the modularity of the chassis technology and designing for a vehicle with recyclability in mind.

Feasibility Study

This project demonstrated the opportunity to utilise lightweighting and other lesser-focused approaches - namely the reduction of the drag coefficient - to develop an L7e vehicle that is innovative, ergonomic, efficient & eco-aware. Zigy proved to be innovative and important to the sector as it focused on the key issues synonymous with PLVs, such as restricted range and lack of end-of-life considerations. Following the feasibility study, DEXET has determined that Zigy has technical and commercial potential worth pursuing further.

Significant Project Outcomes

This project produced an initial vehicle design to be used as a basis moving forward. This included a preliminary chassis design (that utilises an innovative, lightweight joining technology) coupled with detailed packaging of all the essential systems required for a vehicle of this specification. The drag coefficient target, outlined at the beginning of the project, was achieved, and this was partnered with an analysis to prove the importance of aerodynamic efficiency and lightweighting for range extension. Finally, a preliminary bill of materials for a prototype Zigy was detailed alongside potential procurement partners for the production stage.

Next Steps

DEXET will look to create a functioning proof of concept of the underlying chassis in order to evaluate the TRL as part of the NVN POC competition. DEXET will carry out the necessary engineering work to make the prototype more manufacturable, including creating a comprehensive & standardised bill of materials.

Once the technology has progressed to a sufficient TRL level, DEXET will conduct a professional IP analysis and will file patents to protect the technology. Following this and a proof of concept, DEXET will look to present at industry events to highlight Zigy’s innovations and gauge the interest of prospective consumers and potential Investors.

NVN Funding

“NVN’s feasibility study has been essential for Zigy’s progression, allowing the team to explore the concept’s finer details and make significant headway to developing the first prototype. DEXET extends many thanks to the NVN network for the support throughout the project and is excited by the next stage opportunities”
