Abstract
In a method and system for operating a system having an energy storage device and a resistor, and in order to discharge the energy storage device, an electric power that is constant over time is continuously supplied to the resistor, e.g., during a time period, e.g., until the resistor has practically been fully discharged, the time period, e.g., being greater than the time constant of the temperature rise of the resistor induced by a continuous electric power that is constant over time and supplied to the resistor.
Claims25
A method for operating a system that includes an energy storage device and a resistor, comprising:
- continuously supplying an electric power, that is constant over time, to the resistor to discharge the energy storage device.
A system, comprising:
- an energy storage device;
- an inverter;
- a DC/DC converter;
- a supply module that includes a mains-operated rectifier and whose DC-voltage-side terminal is connected to a DC-voltage-side terminal of the inverter and to a first DC-voltage-side terminal of the DC/DC converter, a second DC-voltage-side terminal of the DC/DC converter being connected to the energy storage device;
- an electric motor and/or a three-phase motor connected at an AC-voltage-side terminal of the inverter;
- and
- control electronics adapted to continuously supply an electric power, that is constant over time, to a resistor connected to the energy storage device to discharge the energy storage device.
