Rimac Technology, based in Croatia, has grown from a small startup into one of Europe’s most powerful names in electric battery technology. While most people know Rimac for building the Nevera, the world’s fastest electric hypercar, what’s even more impressive is what’s going on under the surface. Rimac doesn’t just make cars. It builds almost everything in-house, especially its advanced batteries, which are now being used by some of the biggest car brands in Europe.
One of Rimac’s most advanced battery packs stores 120 kilowatt-hours (kWh) of energy using about 4,695 small cylindrical battery cells. These cells are packed in a smart and compact way, thanks to a method called “cell-to-pack,” which skips extra layers and connects the cells more directly. This makes the whole battery lighter, more powerful, and able to hold more energy in a smaller space. Each kilogram of the battery can store around 224 watt-hours (Wh) of energy, which is a big deal for electric vehicles. The battery is also extremely powerful it can produce up to 1,864 watts per kilogram and charge at super-fast speeds of 434 kilowatts. That means faster charging times and better performance on the road.
Rimac is also working closely with BMW on a huge project to create high-voltage EV battery systems. The goal is to build up to 100,000 battery units every year by 2026. This is a major step for Europe, which is trying to reduce its dependence on Asian battery suppliers. Rimac’s role in this project proves that it’s not just building cool cars, it’s building the future of electric mobility in Europe.
And it doesn’t stop with just cars. Rimac has launched another division called Rimac Energy, which focuses on making large stationary battery systems for storing electricity in buildings, homes, and power grids. Their new SineStack system is designed to be super-efficient, over 90% of the energy that goes in can be used again, and it can last through more than 12,000 charge cycles. This means Rimac is not just powering cars, but entire homes and cities in the future.
Other high-end carmakers have also turned to Rimac for help. For example, the Koenigsegg Regera, one of the most exclusive performance cars in the world, uses a 4.5 kWh liquid-cooled battery pack made by Rimac. This shows that Rimac’s battery technology is respected and trusted across the highest levels of the automotive world.
So while Rimac may be best known for building one of the fastest electric cars on Earth, its real power lies in the battery technology it’s developing and sharing with the rest of Europe. Whether it’s powering hypercars, everyday hybrids like the Porsche 911, or entire buildings, Rimac is clearly becoming a powerhouse in the world of energy and electric mobility
