Definitions
- the invention relates to a charging station for electric bicycles for connection to an electrical trailer interface and for reversible mechanical coupling to the trailer hitch and a vehicle with such a charging station and a method for charging batteries or battery units using a vehicle battery via an electrical trailer interface of a vehicle with a trailer hitch using this charging station.
- Electric bicycles so-called e-bikes
- Electric bicycles are becoming increasingly popular for leisure activities. Therefore, electric bicycles are often transported to remote places for use by vehicles such as automobiles or campers. Electric bicycles have a limited capacity of their respective bicycle battery.
- the term "battery" in the sense of the present invention denotes electrically chargeable batteries, so-called accumulators or accumulators.
- the bicycle battery discharges so much that the bicycle battery has to be recharged before the user can possibly reach the usual charging infrastructure at his place of residence again.
- Vehicles do have electrical connections, for example the cigarette lighter socket or internal 220V sockets as in mobile homes.
- the connection options for a charging cable are all inside the respective vehicle, so that an electric cable has to be routed from the inside of the vehicle to the outside to charge the bicycle battery using the vehicle battery, since the electric bicycle is usually not inside the respective vehicle for reasons of space can be loaded.
- the electric bicycle to be charged which is located outside the vehicle when charging, must be supervised during the charging time for reasons of theft protection, which is time-consuming for the respective user, since he cannot carry out any other activities away from the vehicle while the electric bicycle is being charged. If this place in If it is still available inside some vehicles or large mobile homes, such charging inside the respective vehicle should be avoided for reasons of fire protection due to the risk of overheating of the battery to be charged or the charging infrastructure.
- the object of the invention is to provide a charging station that offers a solution for at least some of the disadvantages of the prior art that have been listed.
- the object of the invention is achieved by a charging station for electric bicycles for connection to an electrical trailer interface of a vehicle with a trailer hitch, the charging station having a charging circuit, at least one input interface, preferably a 13-pin input connector, for connection to the trailer interface, at least one output interface for connection to batteries or battery units to be charged, preferably of the electric bicycle, and a housing, the charging circuit being designed at least to convert the electrical voltage provided by the trailer interface to a charging voltage of the battery or battery unit to be charged, and the housing of the charging station for reversible mechanical coupling to the trailer hitch is provided.
- a vehicle's trailer interface may be a trailer socket or plug, typically a 13-pin trailer socket.
- appropriate adapters can be used to connect the trailer interface to the input interface for the charging station.
- the same with regard to the plug/socket/adapter and their possible combinations also applies to the output interface for connection to the battery or battery unit to be charged.
- the vehicles with a trailer interface can be cars, mobile homes or others be vehicles.
- the trailer interface is usually located on the respective vehicle, for example on the rear part of the vehicle.
- the suitability of the charging station for electric bicycles includes the possibility that the battery or battery unit to be charged is not attached to the electric bicycle but is charged separately with the charging station according to the invention. Also included is battery or battery unit charging for purposes other than an electric bicycle.
- the term "electric bicycle” refers to any form of two- or three-wheeled pedal-driven wheeled vehicles that include a battery or battery unit as driving support, including the so-called e-bikes.
- the battery to be charged is referred to as a battery, possibly in a housing with a connection socket for the charging cable.
- a battery unit can be more complex than the battery itself.
- the battery unit can include one or more batteries, all of which are charged when the battery unit is charged.
- the battery unit can include a carrier housing for the batteries and be equipped with additional electronic circuits/components for charging the batteries and/or for operating the electric bicycle.
- the battery pack may also include a mounting system for attaching it, for example, to an electric bicycle.
- the battery unit represents the battery itself.
- the term “battery” in the sense of the present invention denotes electrically chargeable batteries, so-called accumulators or accumulators.
- the conversion of the electrical voltage provided by the trailer interface to a charging voltage of the battery or battery unit to be charged refers to the provision of a voltage adapted to the required charging voltage of the battery or battery unit at the output interface (usually in the range of 36V - 48V DC), which is connected to a so-called DC /DC converter (converter) is generated from the vehicle voltage provided by the trailer interface (usually 12V DC).
- the charging circuit can include several converters (DC/DC converters), each of which provides different charging voltages and to which the output interface can be switched as required.
- the charging station according to the invention can include one or more changeover switches in order to provide the correct charging voltage in each case through one of the converters at the output interface.
- the converter can be arranged in the housing of the charging station or in a connection cable or plug or socket of the charging station for connection to the trailer interface can be integrated. If the converter is arranged in the plug, socket or cable of the electrical connection to the trailer interface, the converter is preferably integrated in a splash-proof manner at the respective point in the plug or socket or cable. This means that the converter can be located outside around the vehicle and enable safe operation there.
- the charging station can have an external dimension of 22.0 cm x 10.6 cm x 6.0 cm.
- the external dimension does not include the electrical cables for connection to the trailer interface and the battery or battery unit to be charged or other electrical cables or cables for other purposes such as data cables, which may be connected to the charging station in addition to the charging cable or connection cable to the trailer interface , with a.
- the cables, starting from the input interface and the output interface can be part of the charging station or can be designed as separate external cables.
- the charging station does not have to be connected directly to the vehicle battery or cigarette lighter socket, which are located inside the vehicle.
- the charging station is therefore a charging station installed outside the vehicle, so that there is no risk of fire for the vehicle during the charging process.
- the charging process can be carried out at any location where the vehicle is located, regardless of the other power supply infrastructure available at this location, whereby the vehicle can even be completely closed during the charging process, since there is no cable from inside the vehicle to the outside of the battery to be charged must be brought out.
- the charging station can also be reversibly connected to the trailer hitch, so that the charging station does not have to be procured for each of the trailers or carriers when there are several trailers or attachable carriers for bicycles or other objects to be transported, but the same charging station according to the invention at any time independently of the trailer or even without a trailer or wheel carrier for charging batteries or battery units can be used easily and reliably.
- the trailer interfaces already present on the vehicles to connect to the charging station the user can handle and operate it quickly and easily.
- the capacity of a bicycle battery is also low compared to the capacity of a car battery, which is automatically charged by the vehicle during ferry operation, so that the charging of the Bicycle battery does not cause any problems for a later start of the vehicle itself.
- an electric bicycle can also be charged several times without having to move the vehicle to charge the car battery in the meantime.
- the charging station according to the invention thus ensures that a battery or a battery unit can be charged easily and safely at any location using a vehicle battery, independently of the external charging infrastructure, and solves at least some of the listed disadvantages of the prior art.
- the charging circuit comprises a microprocessor which is intended to switch off the charging station to protect it in the event of a charging error.
- the charging circuit therefore provides the desirable protection for the battery pack and battery of the vehicle. In this way, the vehicle's battery remains unloaded. If an error occurs due to a short circuit or overcurrent, the microprocessor integrated in the charging circuit provides an error message and switches off the charging station or the charging of the battery or battery unit. The converter of the charging circuit is not destroyed, but automatically returns to its operating state after the error message has been eliminated.
- An integrated fuse can provide additional protection and can be easily replaced.
- the charging circuit additionally provides voltage protection against overvoltages during a charging process, in that the charging circuit comprises an inductor circuit, preferably comprising an overvoltage protection diode, which filters at least high voltages with a high frequency.
- the charging circuit comprises an inductor circuit, preferably comprising an overvoltage protection diode, which filters at least high voltages with a high frequency.
- Electronic circuits that are operated on the voltage network of a motor vehicle must be protected against damage caused by excessive voltage peaks (also referred to as transients).
- the choke circuit performs such a protective function. In motor vehicles, but also in other vehicles, high voltages can occur for a short time. Voltage fluctuations between approx. 8 and 14.4 volts occur at the vehicle battery in normal operation (due to the work of the alternator).
- the choke circuit filters high voltages with high frequency and thus prevents them be forwarded to the downstream electronics of the charging circuit of the charging station according to the invention.
- the overvoltage protection diode becomes conductive at voltages above its breakdown voltage of 15.2 V and short-circuits the input to ground so that longer pulses with excessive voltage are discharged.
- a safety fuse preferably with a maximum load capacity of 1 A, is additionally arranged in the throttle circuit. Since the overvoltage protection diode is intended to cause a short circuit in the event of a fault, a suitable fuse can be installed in the circuit, which is sacrificed in the event of a sustained overvoltage and the associated current flow through the diode. This transient protection is therefore not connected directly to the vehicle battery.
- the charging circuit after being connected to the trailer interface, is additionally designed to supply a test current through one or more connections of the trailer interface, which are provided for the supply of rear lights when the trailer is attached to the trailer hitch, regardless of whether a battery or a battery unit is being charged , so that when the vehicle starts, a corresponding error message is displayed if the charging station is still connected.
- the error message for the rear lamp function provoked in this way, a vehicle driver is made aware of the continuing connection of the charging station to the trailer interface if he wants to start the vehicle, so that the driver is prevented from unintentionally driving off with the charging station and electric bicycle coupled to the vehicle.
- This error message therefore represents a function check to determine whether the charging station is still connected to the trailer plug.
- the test current required for this is minimal, so that it has no significant influence on the charging status of the car battery.
- the housing is splash-proof, and it preferably also consists of a corrosion-resistant material, for example aluminum.
- the aluminum housing for example, defies harsh environmental conditions, protects the sensitive content and is also user-friendly.
- the housing is splash-proof and corrosion-proof, so it is ideally equipped for outdoor use.
- the housing is designed to be connected to the trailer hitch in a theft-proof manner.
- the housing can include a mounting recess suitable for sliding the housing onto a coupling interface, preferably a ball head, of the trailer hitch for a trailer and a safety device, preferably a locking plate, for the lockable connection to the trailer hitch, so that the housing can no longer be removed from the trailer hitch when the safety device is locked Dome interface is removable.
- the charging station according to the invention is thus fixed to the vehicle in a simple and effective manner and cannot be stolen by unauthorized persons.
- the locking plate can be fixed to the trailer hitch and housing with a padlock, for example, so that unauthorized persons cannot detach it.
- the housing comprises a suitable safety cut-out via which a battery or battery unit to be charged or an electric bicycle can be connected to the housing of the charging station in a lockable manner.
- This lockability represents an anti-theft device for the electric bicycle or the battery or the battery unit, so that the charging process no longer has to be monitored by the user the entire time.
- the loading device With the option of attaching the loading device to the trailer hitch, there are additional advantages, especially in the area of anti-theft protection. In this way you can secure your electric bike directly on the vehicle and do not have to use a tree or other options.
- the quick installation and the stable, compact design of this anti-theft device offer many advantages.
- the charging station comprises, preferably on the housing, one or more further fixing devices, by means of which the charging station can be reversibly attached to the vehicle, wheel carrier or trailer, preferably via straps to be attached to the fixing device or devices. This increases flexibility when attaching the charging station to existing objects.
- the charging station is designed for direct mechanical coupling to the trailer hitch.
- the charging station can be coupled to the trailer hitch instead of a trailer and/or bicycle carrier.
- this design there is no provision for another add-on part, for example a trailer or a bicycle carrier mechanically coupled to the trailer hitch, to be connected to the trailer hitch at the same time.
- a direct mechanical The charging station can be protected against theft in a particularly simple manner by coupling it to the trailer hitch.
- the design for direct mechanical coupling with the trailer hitch enables safe storage of the charging station during operation or use.
- the housing includes a further 13-pin interface for the electrical connection to a trailer or wheel carrier.
- the charging station can also be mounted on a wheel carrier or trailer and the batteries or battery units can be charged from there.
- the wheel carrier or trailer can now be connected to the trailer interface via the charging station as an intermediate component via the 13-pin interface, eg a 13-pin socket, of the charging station.
- the charging station also includes a 12V interface, preferably with a watertight cover flap, for the electrical supply of other consumers.
- additional consumers can be, for example, an electrically cooled cool box, a mobile phone, a camera, a drone or other consumers.
- the charging station according to the invention expands the functionality provided by the vehicle with additional connections.
- the charging circuit includes a circuit breaker and/or a power failure sensor and an alarm so that if an electrical connection to the trailer interface is detected as broken, the charging station emits a warning signal, preferably a warning tone, via a corresponding speaker on the charging station.
- a circuit breaker is a contact breaker that can open and close the electrical contacts in a circuit. It is therefore an electronic component that is used in various forms in an electrical circuit. If a person now tries to interrupt the electrical connection to the trailer interface, this contact reacts to the lack of voltage and triggers a warning signal (warning tone). This warning signal can last for 20-30 seconds, for example.
- the same function can also be performed by a power interruption sensor that only detects the power interruption (For example, by disconnecting the trailer interface) and triggers the warning signal accordingly.
- the charging station includes a user interface with which the warning signal can be deactivated, preferably after prior identification of an authorized user via the user interface.
- a user can operate the charging station in a simple and convenient manner and make the appropriate settings, such as interrupting the warning signal so that the electrical connection to the trailer interface can be intentionally interrupted without a warning signal.
- the user interface can be, for example, an input keyboard, a key or something else that allows identification and switching.
- the invention also relates to a vehicle with a charging station according to the invention.
- the invention also relates to a method for charging batteries or battery units, preferably an electric bicycle, using a vehicle battery via an electrical trailer interface, preferably a 13-pin trailer socket, of a vehicle with a trailer hitch using a charging station according to the invention, comprising the following steps: reversible mechanical coupling of the charging station via a housing of the charging station with the trailer hitch;
