Volvo Cars plans to upgrade its EX90 electric SUV from a 400-volt to an 800-volt electrical architecture in future model years, aiming to improve charging efficiency and align with industry advancements. The move will bring the EX90 in line with the recently unveiled ES90 sedan, which already features an 800-volt system.
The current 400-volt EX90 can charge at speeds of up to 250 kW, reaching 10-80% charge in approximately 30 minutes. The transition to 800 volts is expected to significantly reduce charging times when using high-power DC fast chargers.

“We started off with 400 volts on the SPA2 architecture, and then we wanted to upgrade thatāpartly because of range and faster charging speeds; now we can put about 300 kilometers (186 miles) of range on in 10 minutes,” Volvo Cars CEO Jim Rowan told AutoExpress.
“As we go forward, weāll move everything to 800 voltsāweāll upgrade the EX90 in one of the model-year changes,” Rowan added. “And of course, the ES90 starts at 800 [volts], and the EX60 on SPA3 will come out on 800 [volts] as well. That helps us standardize across the platform.”
