Beginning this summer, European leasing customers will drive and evaluate an upgraded demo fleet of 100 Volvo C30 battery electric cars that feature a new, more powerful motor from Siemens and a new 22 kW on-board flexible fast-charger from BRUSA.
The new Siemens motor for the generation II C30 has a peak power output of 89 kW (120 hp) and a torque of 250 N·m (184 N·m), enabling acceleration from 0-70 km/h (0-43 mph) in 5.9 seconds and 0-100 km/h (0 to 62 mph) in 10.7 seconds. The motor in the first generation C30 EV delivered 83 kW (111 hp) and 220 N·m (162 lb-ft).
Siemens is the main supplier of electric propulsion power train components for Volvo’s forthcoming Scalable Product Architecture (SPA) platform, which enables electrification at all level—from different kinds of hybrids to pure electric drive—without intruding on interior or load space.

The strategic partnership between Volvo Car Group and Siemens was formed in August 2011 with the intention to jointly spearhead the development of electrified cars.

The new 22 kW fast-charger is the first on-board charger that operates on a three-phase supply and is small enough to be fitted in an electric car. The BRUSA 22 kW charger supports a single-phase input voltage range of 200-250 V and a three-phase input voltage range three-phase range of 360-440 V; maximum charging current is 60A.
Using a three-phase outlet, a charge of the Li-ion battery pack—24 kWh nominal, of which 22.7 kWh is used to power the car—takes 1.5 hours (total range 164 km / 102 miles according to NEDC certification driving cycle). An ordinary single-phase 230 V household outlet takes 8-10 hours, depending on the available current.

BRUSA Elektronik AG also supplied drivetrain components for the original C30 Electric. Both chargers, the BRUSA NLG5 (3.7 kW) that is installed in the first generation of the Volvo C30 Electric and the new BRUSA NLG6 (22 kW) in the second generation follow the principle of galvanic isolation to ensure maximum electrical safety for the user and the charging infrastructure.
Together with its reinforced insulation, this probably makes the new NLG6 fast charger the safest device on the market, Brusa claims. Because of these safety features, the NLG6 can be used with standard EVSE using basic ground fault detection (RCD) type A.
BRUSA started series production of the NLG6 fast charger last year; Volvo is the second OEM placing an order for it, BRUSA said.
