Prototal was involved from the very beginning when Easee developed its intelligent electric vehicle (EV) charger. Through rapid prototyping using Industrial 3D Printing and vacuum casting, Prototal supported Easee throughout the product development phase, helping transform an innovative idea into a scalable, market-ready solution.
The Challenge
Easee set out to develop a new generation of EV chargers with significantly higher intelligence, safety, and adaptability than existing solutions. The charger needed to:
- Automatically adapt to all car models, power levels, and electrical grids
- Deliver higher power output without compromising safety
- Meet strict quality and regulatory requirements
- Be developed and validated quickly to support rapid market entry
To achieve this, Easee required functional, high-quality prototypes that accurately represented the final product in both form and function.
The Solution
Prototal supported Easee with a combination of Industrial 3D Printing and vacuum casting in polyurethane (PUR) to produce detailed, functional prototypes throughout the development process.
This approach made it possible to:
- Iterate quickly on design and functionality
- Test fit, performance, and user interaction early
- Validate materials, tolerances, and assembly before serial production
- Maintain consistent prototype quality across multiple development phases
By using vacuum casting, Easee could evaluate components that closely matched the look, feel, and performance of injection-moulded parts — without the time and cost of tooling.
Results & Impact
With access to reliable, functional prototypes, Easee was able to refine its charger design efficiently and move confidently toward production.
The result:
- A highly intelligent EV charger with automatic adaptation to vehicles and power grids
- Faster development cycles and reduced risk before market launch
- Successful early market penetration in Norway, followed by rapid expansion across Europe
Easee’s approach demonstrates the importance of using functional prototypes as a foundation for successful product development.
From Prototype to Market Success
Industrial 3D Printing and vacuum casting can even be used in combination. Together, these technologies can accelerate innovation in the rapidly evolving EV infrastructure sector. By combining advanced technology with a structured development process, Easee turned a complex technical challenge into a commercially successful product.
