Rimac Technology’s solid-state battery slashes charging times on Munich debut
A new 100kWh solid-state battery introduced by Rimac Technology at this year’s Munich motor show can be charged from 10% to 80% in just 6.5 minutes, when paired with a fast charger.
Set to debut in the fourth quarter of 2027, the ‘Next-Gen’ 100kWh battery – with its 260 Watt-hours per kilogram (Wh/kg) energy density – was developed in conjunction with Taiwanese battery specialists, ProLogium, and Mitsubishi Chemical Group.
Rimac Technology – the tech arm of the Croatian automaker responsible for the all-electric Concept One and Nevera hypercars – promises that its solid-state solution will be “lighter, safer, and more energy-dense” than its current offerings.
Given its 46XX Gen2 NMC cells are interchangable with existing hardware, they can be altered to fit the requirements of their surrounding package. Moreover, Rimac says that the new battery’s cells and layout allow it to be packaged and cooled more efficiently.

Rimac Technology went on to unveil another battery in Munich, the ‘Evo’ battery.
Set to arrive by mid-2026, the Evo still has a 100kWh capacity but a lower energy density of 214 Wh/kg. This means that users will be forced to endure an agonising charging time of 16 minutes while waiting for the battery to go from 10-80%.
Despite the charging speed figures, Rimac has provided no information about the range of either its Next-Gen or the Evo batteries.
As part of its Munich tech blitz, Rimac Technology also introduced its Sinteg 300 and 550 e-axles. These scalable components are designed for “performance-focused vehicles” from hot-hatches to SUVs and could find their way into high-performance models from well-known brands.

Rimac provides electrical components to a number of manufacturers including Aston Martin, Porsche, BMW and Ceer Motors – the world’s first carmaker from Saudi Arabia. Should it make it to production, Rimac is also expected to supply the in-wheel motors for the rumoured 400bhp Volkswagen ID Polo R.
The Sinteg axles are based on Rimac’s Scalable Powertrain Platform, with the 300 producing 204bhp and the 550 capable of just shy of 490bhp. Rimac also unveiled its next-gen ECUs, which tie into the Software Defined Vehicle (SDV) philosophy.
These components can be updated over the air to remain up to date, and will manage torque vectoring, power and battery systems. When paired with the e-axles and solid-state batteries, these smart ECUs can assist with reducing vehicle weight and boosting efficiency with their sensor-driven approach.

On the back of Rimac Technology’s Munich’s announcements, its COO, Nurdin Pitarević, said: “What we’re showcasing [at IAA] represents the convergence of breakthrough innovation and production readiness.
“These aren’t simply concept technologies; they’ve been developed to be production-ready solutions that will power hundreds of thousands of vehicles in the coming years.”
