Tesla and Panasonic made waves with the launch of the new, 4680 battery. Now, Bugatti Rimac says they have one, too. A better one.
Bugatti Rimac, the Croatian car manufacturer responsible for the outstanding performance of the Porsche Taycan and Pininfarina Battista (among other), continues to expand its EV battery business by developing its own 46 mm battery cells of varying heights, similar to the energy-dense 4680 cells developed by Tesla and Panasonic.
The 4680 name comes from the dimensions of the battery cells, which are 46 mm in diameter and 80 mm in height. Rimac Technology’s head of research and advanced engineering Wasim Sarwar Dilov said that the brand’s cells won’t be limited to just 80 mm and will come in “varied heights” depending on their application.
To work along with the more energy-dense cells, Rimac is working to make the rest of the battery pack more slender to deliver the best conversion efficiency rate possible. The Rimac Nevera is currently at 67%, meaning that the cells account for 67% of a pack’s total mass. Rimac is aiming for an efficiency of 75% before their target production start in 2025.
Rimac has various projects in the works with different automakers, with customer agreements for battery packs including Koenigsegg as well as Aston Martin for its Valkyrie hybrid.
Since its founding in 2009, Rimac Automobili has been developing electric hypercars. Its first, the Concept_One, debuted in 2016 with a production run of only eight units – though it was one of the world’s fastest production vehicles. Its second EV, the Concept_Two, came out in 2018 and eventually evolved into the Nevera (show, at top), which began production this month.
