Inventing the battery of the world's fastest vehicle
When we set out to develop the battery for the Nevera, our mission wasn’t just to compete with internal combustion engines—but to definitively outperform them. The result: the most powerful battery ever integrated into a road car, setting a new standard for the future of performance.
The Vision
Our initial key performance indicators were ambitious, but as the market evolved and competitors made bold announcements, we knew we needed to push beyond our original targets. This required an agile, responsive development approach, one that could adapt quickly to emerging technological landscapes. By selecting the right cell format and optimizing electrical and mechanical integration, we’re always determined to stay ahead of whatever the future holds.
Lean Development
This forward-thinking approach laid the foundation for a development process driven by Rimac-coded ambition—bold, innovative, and always focused on pushing limits. The battery’s peak power output guided every design decision, challenging us to innovate with each iteration. As prototypes evolved, we met every challenge with creativity and collaboration, resulting in a battery that redefined industry expectations. The battery, with its record-setting power output of 1914 HP, sets a new standard in EV technology enabling the Nevera to achieve 0-100 km/h acceleration in 1.8 seconds. With the Nevera R, we’ve further increased the power to astonishing 2017 HP, establishing a new benchmark for high-performance batteries.
Innovative Design
Beyond sheer performance, we reimagined the battery's architecture. The Nevera's battery is a full carbon fiber structural pack, seamlessly integrated into the vehicle's monocoque. This lightweight innovative design stores 120 kWh of energy while actively enhancing the car's torsional stiffness, serving as a testament to our holistic approach to automotive engineering. No groundbreaking project is without its challenges. In this case, the thermal management system was a significant hurdle. We tested dozens of configurations to find the optimal balance between cooling efficiency and weight. This process involved rigorous simulation, but also physical testing under real-world conditions.
To ensure durability, our team subjected the prototypes to rigorous tests. High-speed runs, rapid accelerations and harsh vibrations were just a few scenarios we simulated to identify weaknesses and improve the design. By the end of the prototyping phase, the battery exceeded expectations, proving it could handle both maximum performance and long-term reliability. Technological achievements:
- The highest power battery pack ever integrated into a road legal car
- Exceptional energy density of 169 Wh/kg at the pack level
- A power distribution unit seamlessly integrated within the traction battery
- 450 kW fast charge capability ensuring 20-80% charging in less than 15 min
Setting a New Benchmark
The Nevera battery isn’t just a technological milestone—it’s a bold statement about the future of electric performance. By surpassing traditional limitations, we’ve created a power source that not only rivals internal combustion engines but redefines the very pinnacle of automotive engineering. This achievement reflects the same mindset that drove Mate Rimac to build his own electric powertrain in a garage after his BMW E30 broke down during a race. That same drive to challenge the status quo and redefine what's possible continues to shape everything we do. At Rimac Technology, we’re always looking beyond the horizon—ready to think further, engineer further, and go further.
