Rimac Unveils Next-Generation Solid-State Battery with Ultra-Fast Charging

Rimac Expertise, famend for its electrical hypercars, showcased a brand new lineup of merchandise on the IAA Mobility present in Munich. The centerpiece of their presentation was a groundbreaking solid-state battery platform that may cost from 10% to 80% in simply 6.5 minutes.

Whereas Rimac gained fame with automobiles just like the Nevera, it has lengthy been a key expertise companion for prestigious manufacturers similar to Koenigsegg and Aston Martin, supplying them with battery and powertrain methods. Following an funding from Porsche and a merger with Bugatti in 2021, Rimac has cemented its place as a number one Tier 1 provider and improvement companion for OEMs within the high-performance electrical automobile sector.

Let’s take a better have a look at the important thing new merchandise Rimac unveiled in Munich:

Strong-State Battery Platform: Developed in collaboration with ProLogium and Mitsubishi Chemical Group, this next-gen battery is touted as being lighter, safer, and extra energy-dense than present lithium-ion packs. With a cell-level vitality density of 260 Wh/kg, a 100 kWh pack weighing 470 kg with commonplace lithium-ion cells may very well be diminished to only 384 kg with the brand new solid-state expertise. The corporate additionally claims the battery retains over 95% of its vitality at temperatures as little as -20°C and is free from hearth or explosion dangers on the cell degree.E-Axle Expertise: The brand new “SINTEG 300 & 550” single-motor built-in axles provide spectacular energy densities of over 8 kW/kg and torque densities of 90 Nm/kg, with rotor speeds as much as 25,000 rpm. With energy outputs from 150-360 kW and torque from 2,500-6,250 Nm, these axles are appropriate for every part from small sports activities hatchbacks to giant SUVs.XXL Excessive-Torque Axle: The twin-motor “EDU 550” is scheduled for sequence manufacturing in 2026 for a world producer. It boasts an effectivity of over 95% and an axle torque output of greater than 11,000 Nm.Electronics: Rimac has developed new ECUs based mostly on the NXP S32E2 platform for capabilities like torque vectoring, high-voltage battery management, and over-the-air (OTA) software program updates.Manufacturing Capability: Rimac is aiming to provide tens of hundreds of items monthly from its 95,000 m² campus in Croatia, a €200 million funding. Within the final yr, Rimac has collaborated with main automotive manufacturers together with the BMW Group, CEER Motors, and Porsche.

Rimac Goes Strong-State

Strong-state batteries have lengthy been seen because the next-generation resolution for vitality storage, promising longer vary, quicker charging, and larger sturdiness. Rimac’s new Subsequent-Gen battery package deal is designed to speed up this transition. By combining ProLogium’s solid-state cells, supplies from Mitsubishi Chemical Group, and modern housing strategies, Rimac has created an answer that enhances each vitality density and security.

The battery pack operates in a voltage vary of 540 to 907 volts and makes use of a cell-to-pack structure with pouch-type cells. The cathode accommodates 90% nickel, 5% manganese, and 5% cobalt, whereas the anode is 100% silicon. Not like typical battery packs that use water and glycol, this technique is cooled with a refrigerant fluid and housed in a thermoplastic composite casing.

Probably the most spectacular declare is the charging time: the solid-state battery can go from 10% to 80% in simply 6.5 minutes. This expertise will debut in a high-performance mannequin within the fourth quarter of 2027.
