ETIMER[S] - Electric drivetrain conversion

What it does

The project focuses on preserving existing passenger vehicles and provides a simple and quick solution for converting them to electric drive systems. This not only conserves the vehicles but also prepares them to meet the demands of modern mobility.

Your inspiration

Hardly any issue is discussed as passionately as the future of mobility. I was particularly fascinated by the idea of contributing to the preservation of existing vehicles while simultaneously integrating modern and sustainable technologies to ensure their continued usability. As an entry point into this field, I chose classic cars, as the technical barriers for conversion are lower compared to modern vehicles. Furthermore, classic car enthusiasts represent an ideal target audience to foster acceptance for this type of vehicle retrofit. Nevertheless, the system is also applicable to newer cars.

How it works

The ETIMER[S] System One is based on modularity. It consists of various individual components such as an electric motor, batteries, and an onboard charger. These modules can be combined into a single package via the so-called Cage. This package replaces the internal combustion engine in the existing vehicle. The retrofit follows a plug-and-play principle and connects to existing mounting points in the vehicle. By adapting the Cage, the overall shape of the system can be modified. This allows for broad vehicle compatibility with minimal effort, as the system can flexibly adjust to the spatial requirements of different models. Additionally, the system is expandable and can be upgraded at any time, for example, by adding more battery capacity.

Design process

The process began with a comprehensive target group and market analysis. I spoke with various manufacturers, workshops, and automotive enthusiasts to develop a clear set of requirements. Following that, I analyzed, measured, and digitized vehicles and their different constructions. Since the project also includes a highly technical component, it was important to clarify technical questions with appropriately trained professionals. This led to a clear path, culminating in the system presented here. As a proof of concept, I converted a classic car to electric drive using my approach. The vehicle is a Porsche 912E, an American budget version of the iconic 911. It is now fully electric and ready to drive, currently awaiting road approval.

How it is different

Retrofit solutions for electric conversions are now available to some extent in the semi-professional sector. However, these kits typically consist of non-vehicle-specific individual components, making the conversion process more complex than necessary. Due to the lack of a ready-to-install solution, such projects can quickly become confusing, unpredictable, and ultimately uneconomical. The ETIMER[S] System offers a practical alternative. Thanks to its modular components and various options for vehicle-specific customization, it can be seamlessly integrated into the existing vehicle structure, allowing for quick and easy implementation. This makes the planning and execution of the conversion significantly more practical and efficient. Moreover, the system is designed with scalability in mind, meaning it can grow alongside individual project needs—whether that means adding more battery capacity or adapting to different car models.

Future plans

As the next step, I’m aiming to develop another prototype. The vehicle I converted during the initial project still differs in certain areas from my finalized ETIMER[S] concept. Bringing this final version to life is my main goal for the coming months and years. Along the way, there are still several questions to address—such as how the system kit will be delivered to workshops, and whether smart packaging could help streamline and support the conversion process.
