Abstract
A method controls or regulates the charge state of an electrical energy accumulator of a hybrid vehicle, where, in some operating states, the energy accumulator is charged from a low to a higher charge state level by way of an electric machine driven by an internal-combustion engine of the hybrid vehicle and operating as a generator. The level of the charge state to which the energy accumulator is charged by the internal-combustion engine is selected as a function of a parameter representing the load of the electrical system or correlating thereto.
