Abstract

An electrical booster in an internal combustion engine with an exhaust gas turbocharger is activated so that the electrical booster is connected with the minimum possible power consumption. The connection of the electric booster depends on the power balance, the electric booster being activated when the instantaneously available compressor power of the exhaust gas turbocharger is insufficient to provide the necessary power.
