Volvo is continuing to drop hints about its upcoming high-tech electric sedan, the ES90, ahead of the EV’s official reveal next month. Today, the Swedish automaker provided new details about the ES90’s range and battery efficiency, calling it “a car that goes further and charges faster than any electric Volvo before.”

That’s mostly thanks to the ES90’s new-for-Volvo 800-volt architecture, putting it on par with other fast-charging EVs like the Hyundai Ioniq 5 and Kia EV6. The new architecture is an upgrade from previous Volvo EVs, like the $80,000 EX90 SUV, which features a 400-volt system.

Volvo claims that the ES90 will be able to add 300km (186 miles) of range in just 10 minutes when plugged into a 350kW fast-charging station (depending on the outdoor temperature). Moreover, it will offer a driving range of up to 700km (435 miles) under the more generous WLTP testing cycle.

Automakers are increasingly trending toward higher voltage systems in the hopes of luring in more customers who are turned off by slow charging speeds and the prospect of being stuck at a public charging station for 40 minutes or more. Stellantis, parent company of Jeep and Ram, recently announced a new 800-volt flexible architecture for some of its upcoming EVs.

Volvo said it needed to upgrade a number of its components in order to support the higher voltage system, including battery cells, motors, inverters, and thermal parts. The new motors were lighter and more efficient, and the overall system now creates less heat, meaning the battery can be charged at a faster rate without overloading the electrical system.

Volvo also plans to introduce a new, in-house-developed battery management software for the ES90, provided by Breathe Battery Technologies, which also received investments from Volvo’s corporate venture capital arm. The new software will slash the amount of time it takes to charge from 10 to 80 percent by as much as 30 percent, down to 20 minutes.

The ES90 will also feature a slew of recycled materials, including 29 percent of the aluminum, 16 percent of polymers, and 18 percent of steel. Wood panels inside the ES90 are made from FSC-certified wood, Volvo says. The automaker is also introducing a new blockchain-based battery “passport” to track raw materials like lithium, cobalt, nickel, and graphite used in the battery.
