Electric Driving



Electric Driving







Moving off and driving solely under electric power is possible with a moderate driving style up to a speed of 30 mph (50 km/h). When the E-Power button is pressed (see section "Special functions"), purely electric driving is possible up to approx. 37 mph (60 km/h). The vehicle can drive approx. 1.5 miles (2.5 km) solely under electric power. Current is supplied to the electric motor via the traction battery, which generates 34 kW of power to propel the vehicle. During this time, the combustion engine is switched off and the 12-volt starter battery and the high-voltage battery supply power to the auxiliary units including the vehicle electrical system and consumers (air-conditioning compressor + DC/DC converter).

During operation, the battery manager continually measures the battery charge state and monitors key battery data to prevent critical states such as overheating and exhaustive discharge. Dynamic current limits for charging and discharging are adapted fully automatically. The battery manager then communicates with the hybrid manager and signals whether a load point shift is required to charge the battery or whether discharging is more appropriate to free up capacity for the recovery of brake energy (recuperation).
