New electric car battery promises full recharge in just 18 seconds
In what sounds like science fiction, a British company says it's poised to start producing a battery for electric vehicles that can recharge to full power in an astounding 18 seconds. With a charging time that, if true, is a tiny fraction of what's required for a current EV battery to refill, the VarEVolt battery was designed for hypercars by the UK's performance car company RML Group. VarEVolt says the battery is now set for limited production after the parent company received the Conformity of Production (CoP) approval in June. This UK certification is widely seen as a minimum benchmark for suppliers who wish to work with major automotive manufacturers with reliable results and safety standards. The high-density battery has been trialled in the Czinger C21 hybrid hypercar. For comparison, Porsche says its Taycan - one of the fastest electric cars in the world when it comes to recharging - needs 18 minutes to recharge from 10% to 80%. Such batteries are coupled to ultra-quick electric motors which can zip from zero to 100 km/h more quickly than any liquid-fuelled engine. Mid-range and entry-level electric cars meanwhile often need several hours to recharge. This, combined with the limited range of many EVs, has slowed the switch to electric mobility, given that combustion engine cars can be refuelled in seconds.

This EV battery fully recharges in just 18 seconds — and it just got the green light for mass production

A British firm has received approval to mass-produce an ultra-high-power-density electric vehicle (EV) battery that can be fully recharged in just 18 seconds. The RML Group was granted Conformity of Production certification for its VarEVolt battery on June 2. This government approval signifies that the firm can mass-produce the powerful batteries for EV manufacturers. The certification "underlines our readiness to move from prototyping and niche volumes to supporting larger production contracts," James Arkell, the head of powertrain at RML Group, said in a statement. RML's battery can deliver lots of power in a short span. The VarEVolt battery can supply 6 kilowatts per kilogram, and it's capable of "dumping all its power really, really quickly," RML board member Michael Mallock told Autocar. The battery has a C rating of 200, meaning it's capable of fully charging or discharging in about 18 seconds. In comparison, the fully electric Porsche Taycan's battery has a C rating of around 4 to 5, so it takes 12 to 15 minutes to charge or discharge. The VarEVolt's modular design lets manufacturers tune it for different applications. "We can focus on range, we can focus on power, or we can balance the two," depending on the type of vehicle it will be deployed in, RML Group CEO Paul Dickinson told Autocar. Some small-scale manufacturers are already using the VarEVolt battery; it helps power the futuristic Czinger 21C hybrid hypercar, which relies on a combination of an electric motor that uses energy stored in the battery and an internal combustion engine that burns gasoline.

(Czinger produced just 80 of the luxury sports cars in the first run.) The firm is developing a kit to convert the battery packs in older hypercars, such as the LaFerrari or the McLaren P1, to updated versions, according to Mallock. "For those types of cars, we can do a replacement pack that will significantly increase the range, and if the rest of the hardware within the car would allow it, you could have a version that was eight times the power output," Mallock told Autocar.
