EV charge times down to 90 minutes

When it comes to electric vehicles, the conversation invariably diverts to concerns about vehicle range, infrastructure, and recharge times. To address the last of those issues, Volvo and Siemens have developed a new fast-charging system that cuts recharge times down to 90 minutes.

The system, small enough to fit innocuously inside the vehicle, uses a three-phase outlet to provide enough charge for a range of 164 km (102 mi) in 90 minutes (based on a NEDC certification driving cycle). This compared to a 230-V single-phase household outlet that takes 8 to 10 hours to charge, depending on available current.

A new Siemens electric motor develops peak power output of 89 kW (120 hp) and 250 Nm (184 lb.ft) of torque to the Volvo’s wheels. These figures give the EV a top speed of 125 km/h (78 mph) and a 0 to 70 km/h (42 mph) time of 5.9 seconds. Range is reported at 163 km (101 mi) on a full charge. Via Siemens and Volvo bring EV charge times down to 90 minutes.
