A battery capable of fully recharging in 18 seconds is no longer science fiction. A British company has just received the green light to begin production of this powerhouse. Combustion-engine cars no longer have a say.
Ultra-fast charging has become the new playground for major electric mobility brands. Last March, BYD presented a terminal capable of adding 400 km of autonomy in just 5 minutes. But an even more extreme technology has just entered the scene: a battery that goes from 0 to 100% in just 18 seconds. A technological feat currently reserved for very high-end vehicles.
The British group RML is behind this breakthrough. On June 2, the company obtained production certification for its VarEVolt battery. This official green light allows it to move from prototype to large-scale manufacturing. Already tested on exceptional models, the latter could quickly find its place in other electric vehicles, or even in thermal car conversion projects.
This battery breaks all records with a full charge in just 18 seconds
According to an interview given to the media Autocar, the VarEVolt has a power of 6 kW per kilogram and a C index of 200, which allows it to fully charge or discharge in less than 20 seconds. In comparison, a Porsche Taycan battery has a C index of 4 to 5. This level of performance is nothing like the traditional batteries used in consumer vehicles. The VarEVolt's modular design allows its performance to be adapted according to the desired use: autonomy, power, or a compromise between the two. This level of flexibility opens the way to numerous applications.
Today, this technology already equips the Czinger 21C, a hybrid hypercar. But RML is also developing a retrofit kit for thermal supercars like the LaFerrari or the McLaren P1. The gain is such that it is close to an F1 refueling: 18 seconds is much faster than a traditional fill-up. At this level, thermal cars are simply outdated. It remains to be seen when this technology will reach more accessible models.
