Maximum voltage and Amperes for DC Charging
The extended range EX30 can charge at a maximum of 153kW. With a 150kW charger, it will only charge at up to 150kW (slightly less due to losses). Volvo lists charging speeds with a 175kW charger because, with chargers of 175kW or more, the EX30''s charging limit of 153kW will apply (and therefore the quickest charge time will be experienced).
