BMW i3 concept car exhibited at the 2011 International Motor Show Germany. The i3 concept car was unveiled at the 2011 International Motor Show. [16] [17] This prototype had a 22 kWh (79 MJ) lithium-ion battery pack that delivered between 130 and 160 km (80 and 100 mi). The battery fully charged in about four hours with the 240-volt charging unit.
A motor soft starter is a device used with AC electrical motors to temporarily reduce the load and torque in the powertrain and electric current surge of the motor during start-up. This reduces the mechanical stress on the motor and shaft, as well as the electrodynamic stresses on the attached power cables and electrical distribution network ...
Based on the EA111, this new engine was announced at the 2005 Frankfurt Motor Show, to be first used in the Mk5 Golf GT, the 125 kW 1.4-litre TSI engine is a "Twincharger", and uses both a turbocharger and a supercharger.
