Abstract
The waste shredding device includes at least one shredding shaft, an electric motor for driving the at least one shredding shaft, a mains connection for supplying the electric motor with electrical energy and an energy store for storing energy and for at least partially supplying the electric motor with electrical energy, in particular for covering power peaks. Furthermore, a corresponding method for operating the waste shredding device.
Claims18
A waste shredding device comprising:
- at least one shredding shaft configured to shred feed material;
- an electric motor for driving said at least one shredding shaft;
- a mains connection for supplying the waste shredding device with electrical energy, wherein the mains connection has a predetermined rated power;
- an energy store for storing energy and for at least partially supplying the electric motor with electrical energy for covering power peaks;
- and
- a controller for controlling a flow of energy between the mains connection, the electric motor and the energy store,
- wherein the controller includes a non-transitory computer-readable medium that stores computer code that is executable to:
- determine a power requirements for the electric motor,
- determine the rated power of the mains connection,
- determine when the power requirements for the electric motor exceed the rated power of the mains connection,
- control the flow of energy to the energy store, and
- in response to the determination that the power requirements for the electric motor exceed the rated power of the mains connection, control the flow of energy from the energy store to the electric motor to provide the electric motor with energy from the energy store by at least an amount of which the rated power is exceeded.
A method of operating a waste shredding device, the waste shredding device comprising at least one shredding shaft configured to shred feed material, an electric motor, a mains connection and an energy store, the method comprising the following steps:
- supplying the waste shredding device with electrical power via the mains connection, wherein the mains connection has a predetermined rated power;
- storing energy in the energy store;
- driving the at least one shredding shaft with the electric motor;
- at least partially supplying the electric motor with electrical energy from the energy store to cover power peaks;
- and
- controlling, via a controller, a flow of energy between the mains connection], the electric motor and the energy store, wherein the controller includes a non-transitory computer-readable medium that stores computer code that is executable to:
- determine a power requirement for the electric motor,
- determine the rated power of the mains connection,
- determine when the power requirements for the electric motor exceed the rated power of the mains connection,
- control the flow of energy to the energy store, and
- in response to the determination that the power requirements for the electric motor exceed the rated power of the mains connection, control the flow of energy from the energy store to the electric motor to provide the electric motor with energy from the energy store by at least an amount of which the rated power is exceeded.
