Definitions
- the invention relates to a device for energy management of technical objects, the object-specific functionality of which is implemented with an electric motor drive, the drive having an electric motor and an electric battery, and the battery being designed to provide the electrical energy for operating the electric motor, through its Operation the object-specific functionality of the technical object is realized, as well as a method for operating such a device.
- the respective object-specific functionality is implemented with an electric motor drive.
- electric motors for many decades, the use of electric motors as a drive source was largely limited to mains-powered objects, for example kitchen appliances with a mains cable, machine tools with a permanently installed power supply or rail vehicles with overhead line access.
- the object of the invention is to create a technical solution for energy management with which the usage time of a technical object after a single charge of the battery, in particular the range that can be achieved with a vehicle, can be significantly increased compared to the prior art.
- the object of the invention is achieved in terms of device technology in that the device has a further electric battery and at least one generator in addition to the electric motor and a first electric battery, the at least one generator being operatively connected to the electric motor and being driven at least temporarily by the electric motor via a clutch is, wherein the at least one generator is functionally connected to the additional electric battery and designed to charge this additional electric battery and wherein the additional electric battery is functionally connected to the first electric battery and configured to charge this first electric battery temporarily.
- an additional energy source becomes available, which can recharge the primary battery required for the actual object-specific functionality if required.
- the capacity of the primary battery can be kept at a level that allows a very long period of use without recharging. This has enormous infrastructural advantages, for example in the case of an application for road vehicles, the number of charging stations can be reduced or kept at a low level.
- the additional secondary battery can also be charged when not in use (e.g. storing a hand tool between two work steps at different times) or when stationary (e.g. parking an electric car).
- the additional electric battery is thus also charged in periods in which no electric energy is required to operate the electric motor in order to maintain the object-specific functionality of the respective technical object.
- the first electric battery is also functionally connected to the at least one generator and is designed to drive the generator temporarily.
- the at least one generator can therefore also be operated when the electric motor is at a standstill, so that charging of the additional electric battery is fundamentally possible even in such an operating state.
- a unit for measuring the capacity which is connected to the other electric battery via an evaluation and control unit, is assigned to the first electric battery.
- the battery required for the object-specific functionality can be recharged in good time if required, without it being damaged by overcharging as a result of constant further charging by the other battery.
- the additional electric battery is assigned a unit for measuring the capacity, which is connected to the generator via an evaluation and control unit. This ensures that this additional battery is also recharged in good time and is therefore always available as a reserve capacity for recharging the first battery without it being damaged by overcharging as a result of constant generator operation.
- One embodiment proposes that the generator be arranged on a front side of the electric motor. A very compact design is thus realized, which is particularly advantageous for applications on small technical objects.
- An alternative embodiment proposes that the device has two generators and that one generator is arranged on each end face of the electric motor.
- a compact design is also implemented for technical objects with larger assemblies and/or with a higher energy requirement.
- the object of the invention is achieved in terms of the process in that the further electric battery is connected to the first electric battery if the capacity of the first electric battery has fallen below a previously defined value.
- the unit for measuring the capacity which has already been explained above, is assigned to the first electric battery. This ensures that the battery required for the actual property-specific functionality is recharged in good time if necessary, without it being damaged by overcharging as a result of constant further charging by the other battery.
- a further embodiment proposes that the additional electric battery is connected to an assembly of another technical object in order to at least temporarily assume the function of an independent energy source for the respective other technical object.
- the technical solution according to the invention is suitable for a large number of technical objects whose functionality is implemented using rechargeable batteries with an electric motor drive. This applies to both small technical objects such as kitchen appliances, vacuum cleaners, washing machines, hand tools, garden tools or e-bikes and large technical objects such as road vehicles of various types, rail vehicles, boats, ships or aircraft.
- a technical solution for energy management is created with which the usage time of a technical object can be significantly increased after a single charge of the battery.
- the range that can be achieved with a vehicle can be significantly increased compared to the state of the art, so that the objectively unrealizable wish for "once charge, always drive” is at least subjectively felt a little closer by using the generator to charge the additional electric Batteries are used temporarily in a function similar to a charging station.
- FIG. 1 shows the basic structure of the device in a perspective view.
- FIG. 2 shows the device according to FIG. 1 as a block diagram
- the device shown in the drawing is designed for the energy management of technical objects (not shown), for the function of which an electric motor drive is provided. Regardless of the specific technical object, this drive comprises an electric motor 1 and a first electric battery 2.
- the first battery 2 and the electric motor 1 are electrically connected to one another, this connection being shown in FIGS. 1 and 2 in stylized form by broken lines.
- the first battery 2 is designed to provide the electrical energy to operate the electric motor 1, through its operation object-specific functionality of the respective technical object is implemented.
- the object-specific functionality is determined by the rotating blades of a lawnmower, by the suction effect of the blower in a vacuum cleaner, or by the rolling motion of the wheels in an electric vehicle.
- the device has a further electric battery 3 and at least one generator 4 in addition to the electric motor 1 and the first electric battery 2 .
- at least one generator 4 in addition to the electric motor 1 and the first electric battery 2 .
- two generators 4 and 5 are provided.
- a generator 4 or 5 is arranged on each end face of the electric motor 1 .
- Both generators 4 and 5 are operatively connected to the electric motor 1 and are driven at least temporarily by the electric motor 1 via a clutch 6 .
- one generator 4 is also directly operatively connected to the first battery 2, this connection being shown stylized in FIGS. 1 and 2 by two broken lines.
- the generator 4 can also be operated without being connected to the electric motor 1 via the clutch 6 .
- This is particularly advantageous in operating states in which no electrical energy is required to operate the electric motor 1 in order to maintain the object-specific functionality of the respective technical object, such as when a hand tool is temporarily not in operation or when an electric car is stopped in front of a traffic light. Even in such operating states in which the electric motor 1 is not in operation, the operative connection between the first electric battery 2 and the generator 4 makes it possible to charge the further electric battery 3 .
- the two generators 4 and 5 are functionally connected to the additional electric battery 3 and are designed to charge this additional electric battery 3 .
- the additional electric battery 3 is functionally connected to the first electric battery 2 and designed to temporarily charge this first electric battery 2 .
- the electrical connections between the additional electrical battery 3 and the first battery 2 and the two generators 4 and 5 are each shown in stylized form in FIGS. 1 and 2 with dash-dotted lines.
- the first electric battery 2 is assigned a unit for measuring the capacity (not shown), which is connected via an evaluation and control unit (not shown) to the other electric battery 3 is connected.
- another electric battery 3 associated with a unit for measuring the capacity (not shown), via an evaluation and control unit (not shown) with the generators 4 and 5 is connected.
- a device constructed in this way can be used for various types of technical objects, for example the device is structurally integrated in a vehicle.
- the additional electric battery 3 is connected to the first electric battery 2 if the capacity of the first electric battery 2 has fallen below a previously defined value.
- the additional electric battery 3 is preferably charged by the two generators 4 and 5 only at time intervals in which no power or only a proportionate power is required from the electric motor 1 to maintain the object-specific functionality of the respective technical object.
- a device constructed in this way can be used for other applications (not shown in the drawing).
- the additional electric battery 3 can be connected to an electric battery of another technical object in order to at least partially charge this electric battery of the other technical object.
- the additional electric battery 3 can be used temporarily as a charger for a battery of another technical object.
- the additional electric battery 3 can assume the function of a mobile charging station for other vehicles.
- the additional electric battery 3 can be connected to a subassembly of another technical object in order to briefly assume the function of an independent energy source for the respective other technical object.
- the additional electric battery 3 can assume the function of a short-term emergency power supply for the associated house.
