Definitions
- the invention relates to a method for delivering charging current for an electric vehicle and for storing electric current in a charging column with the steps of starting a process for charging an electric vehicle, starting charging a battery in the charging column, ending the process for charging a electric vehicle, ending the charging of a battery in the charging station, the charging of the electric vehicle and charging of the battery in the charging station taking place in parallel.
- PRIOR ART The spread of electric vehicles that are operated with an electric motor is accompanied by a functioning infrastructure for charging the electric vehicles. In addition to charging at home, users of electric vehicles must also be given the opportunity to obtain energy in the public sector. With the currently available ranges of electric vehicles, it is necessary for the vehicles to be able to be charged outside of the home environment.
- charging stations must be provided in public areas in order to ensure constant availability of energy for electric vehicles through a supply network.
- Charging stations are known for charging the traction battery of a plug-in vehicle—hybrid or electric vehicle—that have a chargeable electrical energy store (battery) to deliver the electrical energy stored therein to an electric vehicle to be charged when needed.
- a charging station is disclosed, for example, in the document DE 10 2010 043 516 A1.
- the charging station presented here is connected to a power grid that provides the electrical energy for charging an electric vehicle.
- Such a charging station requires in particular for a Rapid charging of an electric vehicle has high connection costs, cannot be set up flexibly and is not scalable if the charging capacity is to be increased.
- Charging stations are also known which have an energy conversion device arranged in the charging station, for example an internal combustion engine. Such charging stations do not have an electrical energy store that can be used, for example, to temporarily increase the charging capacity of the charging station. It is therefore the object of the present invention to provide a method for charging electric vehicles, with which charging is possible more quickly and more cost-effectively. The object is achieved by means of the method for generating and delivering charging current for an electric vehicle in a charging station according to claim 1. Further advantageous embodiments of the invention are set out in the dependent claims.
- the method according to the invention for generating and delivering charging current for an electric vehicle in a charging station has four method steps: In the first method step, a process for charging an electric vehicle is started.
- the charging process for charging an electric vehicle begins with the registration of a first initial process for charging an electric vehicle.
- the first initial process can take place, for example, by registering the user via a smartphone, for example. It is also possible to detect an electric vehicle to be charged by sensors arranged in the charging station, by entering data into the HMI unit or by connecting the charging cable to the electric vehicle to be charged. Alternatively or additionally, an energy conversion of an energy conversion device can begin. Also alternatively or additionally, the start of a charging process for an electric vehicle can start in that the charging cable is connected to the electric vehicle to be charged and a user issues a start command to start charging. In the second method step, the charging of a battery arranged in the charging station is started. In the third step, an operation for charging an electric vehicle ends.
- An electric motor vehicle can be charged by disconnecting the charging cable or by entering a stop command from a user.
- the charging of a battery arranged in the charging station is terminated.
- the charging of an electric motor vehicle is usually also stopped.
- it is also possible to continue charging the battery for example when the battery charge level is low.
- the charging of the electric vehicle and the charging of the battery arranged in the charging station take place at the same time.
- a process for charging an electric vehicle and a charging process are understood to mean not only the delivery of electrical energy to an electric vehicle but also the start and termination of the delivery of electrical energy to an electric vehicle.
- a process for charging an electric vehicle is understood to mean in particular the start of an energy conversion, eg from a liquid and/or gaseous energy carrier into electrical energy, the actual process of energy conversion and the termination of the energy conversion.
- An electric vehicle within the meaning of this document is a motor vehicle which is at least partially driven by an electric motor which, in order to drive the motor vehicle, must be supplied with electricity from an electrical energy store arranged in the motor vehicle.
- Such electric vehicles are, for example, purely electric vehicles (BEV), also plug-in hybrid vehicles, e-scooters, e-scooters, e-bikes
- the term battery means any form of energy storage for storing electrical energy, such as a flywheel or electrolysis.
- a charging station is understood to be a charging device that, due to its compact design, can be placed on a narrow sidewalk or replace a fuel pump at a gas station, but is at most smaller than the footprint of a standard car parking space.
- the charging station is designed as a column, ie it has a height H that is at least 20% greater than its width B and/or depth T.
- a charging station within the meaning of this invention has no space that can be entered by a human.
- a charging station is therefore not a container and also not a building or power plant that is intended to generate energy greater than 10MW.
- the charging stations according to the invention have a very compact design, in which the structure is adapted to the dimensions and not - as for example in container solutions - the standard size of the housing dictates the external dimensions.
- the ratio of the volume VN used for cooling by components and/or the air duct to the enclosed volume VG is 0.7 or more (VN/VG > 0.7), preferably 0.8 (VN/VG > 0 .8) or more and more preferably 0.9 or more (VN/VG>0.9).

- the maximum height is 3 m, preferably 2.5 m, particularly preferably 2.25 m.
- the charging station is suitable and intended for charging electric vehicles with a charging capacity of >75 kW, preferably >100 kW and particularly preferably >125 kW.
- An electric vehicle is therefore charged with a charging capacity> 50 kW, preferably> 100 kW and particularly preferably> 125 kW. This has the advantage that electric vehicles can be charged quickly and the charging station only takes up a short time.
- the charging power delivered to the electric vehicle during a charging process is greater than the charging power provided by an external and/or internal energy source.
- the advantage of this is that the charging time can be significantly reduced by using an additional energy store.
- the external energy source can be a grid connection that is connected to the mains or an external generator unit.
- the internal energy source can be an energy conversion unit that is intended and suitable for generating electrical energy through energy conversion.
- the battery arranged in the charging station usually supplies the components arranged in the charging station with electrical energy.

- the energy conversion device can be operated in an optimal operating mode, eg an advantageous load.
- the electrical energy is generated in the charging station.
- the energy conversion unit generates a primary charging current. Energy conversion from a liquid and/or gaseous energy carrier into a charging current, for example by means of an internal combustion engine or a fuel cell, is preferred.

- the course of the charging power P is shown here for an electric vehicle to be charged, which has an active temperature control of the battery of the electric vehicle in order to avoid damage to the battery of the electric vehicle during the charging process and at the same time to achieve a high charging power with direct current enable.
- the charging station 1 used is a such as shown in Fig.1, thus has an energy conversion device, here an internal combustion engine M.
- an energy conversion device here an internal combustion engine M.
- the energy conversion of the energy conversion device M is started, the energy conversion of the fuel stored in the tank unit T into electrical energy takes place by the internal combustion engine M.
- the Motor M requires a certain time until the moment t1, at which the motor M has reached the operating temperature and the required speed, until the maximum charging power is available, 200 kW in this exemplary embodiment. This process protects the motor M and reduces wear.
- the entire charging power generated up to this point in time t1 is conducted completely into the battery B to charge it.
- point in time t1 is 30 s after point in time t 0 and marks a local maximum of the charging power of battery B. From point in time t 1 , the charging power that is delivered to the electric vehicle to be charged increases very steeply, while the power delivered to the battery B also drops sharply. At time t2 (50 s after time t0), the slope of the increase in the charging power that is delivered to the electric vehicle to be charged is at its maximum. At time t 5 (1 min after time t 0 ), the power for charging the battery B and for charging the electric motor vehicle reach the same values.
- the point in time t A designates the point in time at which the increase in the charging power of the electric motor vehicle to be charged decreases.
- the increase in charging power delivered to the electric vehicle becomes smaller.
- the charging capacity of the electric vehicle to be charged is 90% of the maximum charging capacity.
- the curve of the charging power delivered to battery B flattens out.
- the point in time t A depends on the type of electric vehicle to be charged and is around 25-30% of the total charging time t G .
- time tM later than time tA, the charging power of the electric motor vehicle reaches the global maximum, at the same time the global minimum of the charging power of battery B is at this time.
- Time t33 denotes the time exactly in the middle between time tA and the time tM.
- the point in time t 4 designates a point in time between the point in time t 3 and the point in time of the end of the charging process t G .
- the negative slope of the drop in the charging power of the electric motor vehicle is at its maximum, and at the same time the positive slope of the increase in the charging power of the battery B is at its maximum.
- the charging process for charging an electric vehicle ends at time t G .
- the user ends the charging process by entering a stop command in the HMI unit H or removes the charging cable from the electric vehicle.
