Stunned with electric car battery fully charged in just 18 seconds

As the world moves rapidly towards electrification, high-end supercars are also moving away from the roar of internal combustion engines, giving way to electric motors – which can help the car accelerate from 0 to 100 mph in just a few seconds.

However, to achieve that “lightning-fast” performance, an electric powertrain needs a battery pack that can deliver a huge amount of power instantly, but this often comes at the cost of significantly shortening driving range.

RML Group has solved this problem for supercar manufacturers with VarEVolt – the battery pack with the highest energy density today, which is being deployed for hybrid supercars. RML's VarEVolt battery pack is currently the battery pack with the highest power density in the global automotive industry.

VarEVolt, a battery pack specifically designed for hypercars by RML Group (UK), is now ready for mass production and commercialization, after the parent company received Conformity of Production (CoP) certification.

This certification, issued after a comprehensive audit of the quality management system, confirms that the battery pack meets the United Nations Electric Vehicle Regulation No. 100 (UN ECE R100). This is an important technical requirement for components used in electric vehicles.

RML's batteries can deliver a lot of energy in a short period of time. The VarEVolt battery can deliver 6 kilowatts per kilogram and has the ability to discharge energy really quickly, said RML board member Michael Mallock.

This battery is in the C 200 class, meaning it can be fully charged or discharged in about 18 seconds. Meanwhile, the battery in the all-electric Porsche Taycan is in the C class of about 4 to 5, so it takes 12 to 15 minutes to charge or discharge.

Several small-scale manufacturers are now using VarEVolt batteries. They help power the futuristic Czinger 21C hybrid supercar, which relies on a combination of an electric motor that uses energy stored in the battery and an internal combustion engine that burns gasoline.

“This certification underlines our readiness to move from prototyping and small-volume production to supporting larger production contracts,” said James Arkell, director of powertrains at RML Group.

Currently, RML only produces a small number of VarEVolt batteries, but future large-scale production won't be limited to exclusive products like the Czinger 21C, a luxury sports car with an initial production run of just 80 units.

According to Mr. Mallock, the company is developing a kit to convert the battery packs in older supercars like the LaFerrari or McLaren P1 into updated versions.

“For electric vehicles, we can create an alternative package that significantly increases the range, and you can have a version that has eight times the power output,” Mallock said.
