SEGULA Technologies joins PERRINN to develop the battery system for the Project 424 100% electric hypercar

  • SEGULA Technologies joins PERRINN as a technical partner and participates in the development of the Project 424 lithium-ion battery cooling system
  • The project consists of developing and building a 100% electric prototype with a view to taking part in the world’s greatest endurance race, the 24 Hours of Le Mans, within 5 years. Before this deadline, the objective is to achieve a new lap record on the most demanding circuit on the planet: the Nürburgring Nordschleife.
  • The open source spirit of Project 424 also provides a unique opportunity for young engineers to contribute to the success and development of this electric race car, while learning from other more experienced designers and engineers.


Paris, October 26, 2021 – SEGULA Technologies joins forces with PERRINN to accelerate the development of
Project 424.

This 100% electric hypercar is equipped with a lithium-ion battery system. This is a high-performance energy storage technology that is compatible with the prototype’s sporting performance. It has the best energy and power density of any energy storage solution. This means a lighter car and increased performance for a future speed record.

As a technical partner of the 424 Project, SEGULA is contributing to the development of the lithium-ion battery cooling system with its know-how and experience in numerical simulation, especially in computational fluid dynamics (CFD).

The objective is to develop a system that is both efficient enough to break a new speed record and robust enough to last 24 hours. Among the various approaches tested, the solution chosen is a cooling system using a heat transfer fluid that circulates around the cells of the battery pack

Developed in-house on the PERRINN open source platform, updates and improvements can be made in real time.

Thanks to this transparent and collaborative approach, everyone can see the day-to-day development of this incredible vehicle, which is already in an advanced digital prototype phase.

Nic Perrin, founder and chief engineer of, said: “With SEGULA, we have found an ideal partner who will help us push the technical limits of the 424 project. So far, the Group has been invaluable in helping us develop the cooling system for our lithium-ion battery system.”

Laurent Lanquetin, head of SEGULA’s computing department, comments: “We are very proud to be taking part in this technological and scientific challenge, which demonstrates the performance of electric motors in automobile racing. This is a considerable challenge, as we are tackling one of the most prestigious endurance races in the world: the 24 Hours of Le Mans.

Moreover, the 424 project being open source, it allowed us to work and exchange with engineers specialized in different fields, spread all over the world. Our work has been a real research and innovation project, which fascinates engineers and students. We intend to continue our collaboration over the next few years, to complete the design of the Hypercar 424.”

This project confirms SEGULA Technologies’ expertise in the field of electric racing. In particular, the Group designed the Electric Formula EF01, the first fully electrically powered single-seater at the highest level of sport, and also participated in the Andros car.
