Description

The invention relates to a charging station, in particular for electric vehicles, having at least one photovoltaic module.It is known that a charging station, in particular for electric vehicles, has a daily standby power consumption of 12 kW to 24 kW without taking into account charging processes. This standby power must be taken from either a public power grid or an integrated electrical energy store-if the charging station has such an electrical energy store and is optionally not connected to the public power grid. This disadvantageously results in additional costs for operating the charging station. Furthermore, the electrical energy store-in particular in the case of charging stations which are not connected to the public power grid-must be replaced and / or charged more frequently, as a result of which additional costs are incurred. Furthermore, the daily standby power consumption, which is covered therewith by conventionally generated electrical power, has a negative effect on a CO 2- balance of the charging column.The object of the invention is therefore to provide a charging station having at least one photovoltaic module, wherein the disadvantages mentioned are at least reduced, preferably do not occur.The object is achieved by providing the present technical teaching, in particular the teaching of the independent claims and of the preferred embodiments disclosed in the dependent claims and the description.The object is achieved in particular by providing a charging station, in particular for electric vehicles, in particular for electric cars or trucks, having a housing, an electrical energy store and at least one photovoltaic module. The at least one photovoltaic module is mechanically connected to the housing. In addition, the at least one photovoltaic module is electrically connected to the electrical energy store, such that the electrical energy store can be charged with electrical power generated by the at least one photovoltaic module. Advantageously, a CO 2- balance of the charging column is thus improved, since charging of the electrical energy store with conventionally generated electrical power is reduced. Advantageously, the standby power consumption can also be covered at least partially, preferably completely, with electrical power generated by the at least one photovoltaic module, which further improves the CO 2- balance.In electrical engineering, the term charging station refers to any, in particular stationary or mobile, device or electrical installation which serves to supply energy to mobile battery-operated devices, machines or motor vehicles by simple adjustment or insertion without having to necessarily remove the energy store-for example the traction battery of an electric car. Charging stations for electric cars are sometimes also referred to as "electric power stations" and may comprise a plurality of charging points. In particular, direct current fast charging systems (high performance charging systems or high power charging systems, HPC systems) such as the so-called combined charging system (CCS) widely used in Europe are known here. In the case of direct current charging of the generic type, direct current is fed from the charging station directly into the battery of the vehicle and is provided for this purpose by a powerful rectifier, preferably the charging station, from the power grid or by large buffer accumulators at, for example, solar charging stations. A battery management system is located in the vehicle, which communicates directly or indirectly with the charging station in order to adjust the current intensity and voltage or to end the process when a predetermined capacity limit is reached. Power electronics are usually located in the charging station. Since the DC terminals of the charging station are connected directly-without detour via an AC / DC converter of the vehicle-to corresponding terminals of the traction battery, high charging currents with low losses can be transmitted, which enables short charging times.In one embodiment, the charging station is designed as a charging column. In particular, the charging station has at least one charging point, in particular exactly one charging point or exactly two charging points.In particular, the charging station is designed as a rapid charging station. In one embodiment, the charging station is designed as a battery-supported charging station, in particular as a battery-supported rapid charging station.In particular, the at least one photovoltaic module generates the electrical power as direct current. Alternatively, the at least one photovoltaic module generates the electrical power as an alternating current.In particular, the charging station is designed to be electrically autonomous and therefore in particular not connected to the public power grid-in particular called island charging station. Alternatively, the charging station is electrically connected to a public power grid-in particular called a grid charging station.In particular, the charging station has a rectifier. The rectifier is configured to convert an alternating current of the public power grid into a direct current for charging the electrical energy store. Alternatively or additionally, the rectifier is configured to convert an alternating current of the at least one photovoltaic module into a direct current for charging the electrical energy store. In particular, the charging station can have a plurality of rectifiers, wherein a first rectifier is configured to convert an alternating current of the at least one photovoltaic module into a direct current for charging the electrical energy store, and a second rectifier is configured to convert an alternating current of the public power grid into a direct current for charging the electrical energy store.In one configuration, the at least one photovoltaic module generates the electrical power as direct current and is electrically connected directly to the electrical energy store.In particular, a photovoltaic module of the at least one photovoltaic module has a width of 150 cm to 200 cm and a length of 50 cm to 100 cm.

It is thus possible to operate the at least one operating device directly with the electrical power generated by the at least one photovoltaic module. In addition, the at least one operating device is electrically connected in particular to the electrical energy store. In particular, the charging station has a standby power consumption-in particular a power consumption without the output of electrical power for charging a motor vehicle-of 500 Wh to 1000 Wh, so that 12 kW to 24 kW are taken from the electrical power store daily for operating the charging station. Advantageously, the electrical energy of the electrical energy store is thus used at least only partially-in particular only when the at least one photovoltaic module does not generate electrical power-for standby operation of the charging station and potential charging processes are available.In particular, the electrical energy store has a capacity of 280 kWh. The electrical energy store of a charging station without a photovoltaic module is thus emptied after approximately 10 to 23 days at a daily standby power consumption of 12 kW to 24 kW and without charging processes. The at least one photovoltaic module advantageously increases the duration until the electrical energy store is emptied during such a standby power consumption and without charging processes.In particular, a photovoltaic module of the at least one photovoltaic module has a power of at least 300 W p. In the context of the present technical teaching, this means that the one photovoltaic module of the at least one photovoltaic module has a rated power according to standard test conditions-at a photovoltaic module temperature of 25° C., an irradiance of 1000 W / m 2 and a sunlight spectrum according to AM=1.5-of at least 300 Wh. In particular, an electrical power of 200 kW to 300 kW is generated in the year by means of the one photovoltaic module, so that the electrical energy store can be charged once per year by means of the one photovoltaic module. In an embodiment in which the charging station is electrically connected to a public power grid, costs in the range from 60 . In an embodiment in which the charging station is designed to be electrically autonomous, a single charging of the electrical energy store-including costs for employees and logistics-costs approximately 400 begin- erally, so that costs at the level of 400 begin- erally can be saved by a single photovoltaic module.
