Definitions

  • the invention relates to a method for generating and delivering charging current for an electric vehicle in a charging station with the process steps of registering a first initial process for charging an electric vehicle, starting a process for energy conversion, starting a process for charging an electric vehicle, ending the process for energy conversion and Completion of the process of charging an electric vehicle, as well as a device for carrying out the process.
  • Charging stations are known for recharging the traction battery of a plug-in vehicle - hybrid or electric vehicle - as described, for example, in DE 102009016 505 A1.
  • the charging station itself is connected to a power rail for the power supply.
  • An existing power grid has a connection element for outputting electrical energy to an electric vehicle. It is therefore the object of the present invention to provide a method for charging electric vehicles with which the charging time can be reduced. Another object of the present invention is to provide a corresponding device.
  • the method according to the invention for generating and delivering charging current for an electric vehicle in a charging column has five method steps.
  • a first initial process for charging an electric vehicle is registered.
  • the first initial process signals the readiness of a user to charge an electric vehicle.
  • the first initial process can be registered by an active user input in the immediate vicinity of the charging station.
  • An entry in an HMI unit at the charging station is possible, for example.
  • Input via a smartphone or the vehicle from a spatial distance to the charging station is also conceivable.
  • the first initial process can, however, advantageously also be registered without active user input, e.g. by parking an electric vehicle to be charged in the immediate or indirect vicinity of the charging station.
  • an energy conversion process is started.
  • an energy conversion requires a certain amount of time in advance in order to be able to deliver maximum power to the electric vehicle during a charging process.
  • the lead time for an energy conversion from light to electricity by a solar cell or wind to electricity by a wind turbine is less than the lead time for an energy conversion of a liquid and / or gaseous energy source by an internal combustion engine, for example.
  • the charging process for a user is significantly reduced by a suitable choice of the starting point in time for energy conversion by means of an internal combustion engine.
  • a process for charging an electric vehicle is started. Due to the method according to experience, the charging station emits electrical energy to the electric vehicle during the charging process. During the charging process, the electric vehicle is connected to the charging station via a charging cable. Inductive charging of the electric vehicle is also possible.
  • the energy conversion process is ended.
  • the device for energy conversion is stopped or stopped.
  • the process for charging an electric vehicle is ended. This can be done e.g. by user input, disconnecting a charging cable or automatically when the electric vehicle is fully charged.
  • the ratio of the amount of electrical energy EK generated during the charging process to the amount of electrical energy EA delivered to the electric vehicle to be charged is greater than 1 (EK / EA> 1).
  • the charging process includes process steps two to four, i.e. from the start of an energy conversion process to the end of the process for charging the electric vehicle to be charged.
  • the charging process therefore includes the actual process for charging an electric vehicle and also the process of converting energy in the charging station.
  • the additional excess energy generated during the energy conversion process for the charging process can be used to charge the electric vehicle to be charged and / or another electric vehicle.
  • the charging time for this additional second electric vehicle can thus also be shortened if, after a first electric vehicle has been charged, the energy EA is fed into the second electric vehicle, i.e. the nominal power of the charging station is available for the second electric vehicle.
  • the inventive method therefore shortens the duration of a Charging an electric vehicle by storing the more energy generated during the charging process and transferring it to an electric vehicle to be charged when required.
  • a charging station is understood to mean a charging device which, due to its compact design, can be placed on a narrow sidewalk or can replace a fuel pump at a gas station, but is at most smaller than the footprint of a standard car parking lot.
  • the charging column is designed as a column, ie it has a height H which is at least 20% greater than its width B and / or depth T.
  • a charging column in the context of this invention has no space that can be entered by a person .
  • a charging station is therefore neither a container nor a building. Rather, the charging columns according to the invention have a very compact design, in which the structure is adapted to the dimensions and not - as is the case with container solutions, for example - the standard size of the housing dictates the external dimensions.
  • the ratio of the volume VN to the enclosed volume VG used by components and / or the air duct for cooling is 0.8 or more (VNA / G> 0.8), preferably 0.85 (VN / VG> 0 , 85) or more and particularly preferably 0.9 or more (VNA / G> 0.9).
  • the energy conversion device supplies more than 50% of the total charging power of electrical energy of a charging process of an electric vehicle, preferably the energy conversion device supplies more than 75% of the total charging power of electrical energy of a charging process of an electric vehicle, particularly preferably more than 90%.
  • the charging column works autonomously and the energy conversion device supplies 100% of the total charging power of electrical energy from a charging process of an electric vehicle.
  • methanol and / or ethanol are converted into electrical energy.
  • the ratio of the amount of electrical energy generated during the charging process is EK to that to be charged Electric vehicle emitted amount of electrical energy EA and the amount of electrical energy loss EV greater than 1 (EK / (EA + EV)> 1).
  • the energy loss EV denotes the difference, which is unavoidable for technical systems, between the electrical energy EK generated during the energy conversion process and the useful energy emitted during an energy conversion.
  • the energy loss EV is mainly given off as thermal energy to the environment.
  • the amount of electrical energy loss EV does not include the amount of electrical energy required, consumed and / or stored for operating the charging station.
  • a charging station can generate or provide more electrical energy than that actually required for charging.
  • the method according to the invention therefore not only compensates for the energy loss EV that is present in every technical device, but also generates significantly more electrical energy EK during the charging process, which is stored and available for other applications, e.g. processes for charging electric vehicles.
  • the amount of more energy EM EK - (EA + EV + ES) is greater than or equal to 1 kWh.
  • the more generated energy EM is therefore significantly higher than is required to compensate for the lost energy EV and to ensure the charging of an electric vehicle and the operation of the charging station.
  • the more generated energy EM is essentially stored both for the operation of the charging station and in an energy store and used for further charging processes to charge electric vehicles. The rapid availability of the stored energy therefore shortens the charging time of the following charging processes, since energy is available for charging before the energy conversion device can deliver a charge.
  • the energy conversion comprises the conversion of a liquid and / or gaseous energy carrier into electrical energy.
  • the energy source can be a conventional gasoline or diesel fuel, but preference is given to an alkanol (methanol, ethanol and / or a mixture of methanol and ethanol) which can be produced from organic substances in a CO2-neutral manner and has long been tried and tested as a fuel.
  • Liquefied or compressed gases, such as natural gas or hydrogen, can also be used as fuel.
  • the device for energy conversion is usually an internal combustion engine; a fuel cell, for example a fuel cell, is also possible Methanol-powered direct methanol fuel cell or one powered by hydrogen
  • the liquid energy carrier is stored in a tank in the charging station.
  • the storage of the tank in the charging station itself reduces the space required by the charging station.
  • the tank is suitably designed depending on the type of energy carrier used and is corrosion-resistant to the energy carrier used. If liquefied or compressed gases are used, e.g. natural gas or hydrogen, the tank is also thermally insulated or pressure-tight.
  • the tank can be made in one piece or in several pieces. It is also possible to design the tank as an interchangeable tank, with which the charging station can be supplied with fuel more easily and quickly by exchanging the empty tank for a full tank and refilling it externally.
  • the type of energy generation by the energy conversion device is the only energy source that provides electrical energy to supply a charging process.
  • the electrical energy is temporarily stored in a battery.
  • the energy source for the energy conversion is methanol and / or ethanol.
  • the energy conversion device is an energy conversion direction which is suitable, provided for and designed to convert ethanol and / or methanol into electrical energy.
  • the battery is connected to the generator unit via a power line.
  • the power line is suitable and provided for storing the electrical energy transmitted by the generator unit in the battery.
  • the stored energy can be used both for the operation of the charging station and for other processes for charging electric vehicles and thus the charging time shorten.
  • a charger can be placed between the generator unit and the abbey.
  • the ratio of the amount of electrical energy EK generated during the charging process to the amount of electrical energy EA delivered to the electric vehicle to be charged is greater than 1, ie the charging station 1 generates more electrical energy than is delivered to the electric vehicle.
  • the more generated electrical energy power in this embodiment is 30 kW, according to the invention between 1 kWh and 50 kWh more energy generated during the charging process. This amount of more energy generated depends, among other things, on the duration of the charging process or on the charging power with which an electric vehicle is charged.

  • the battery B is connected to the connection device A for the charging cable via an inverter WR.
  • the GW inverter acts as a power unit that sets the charge status of the electric vehicle to be charged, the charging voltage and the charging current of the charging station.
  • a first electric vehicle to be charged is charged with around 150 kW direct current
  • a second electric vehicle to be charged with 50 kW alternating current from the battery B.
  • the process for charging an electric vehicle begins with a registration of a first initial process. Up to this point in time, the charging station 1 is in an idle state (stand-by) in which only the control unit S, the communication unit K and the HMI unit H are ready for operation. These units H, K, S are supplied with energy by the battery B. The control unit S, the communication unit K and the HMI unit H require 70 W for stand-by operation.
