Definitions
- the present invention relates to a method for operating a charging station for vehicles with an electrical energy store and a charging station which is designed to carry out such a method.
- Vehicles with an electrical energy store in particular hybrid and / or electric vehicles, can be supplied with electrical energy via a charging station.
- the suitable charging stations are integrated into a multiphase, in particular three-phase, voltage network, a charging station providing several phase lines for the electrical power supply of the vehicles.
- the electrical energy store of the respective vehicle is charged in a single phase, the vehicle being supplied with a charging current via a phase line.
- a large number of vehicles can also be supplied with corresponding charging currents via a phase line.
- the electrical energy is not temporarily stored in the voltage network, it is necessary for stable operation of the voltage network that the electrical energy produced essentially corresponds to the electrical energy consumed by electrical consumers. If consumption and energy generation are no longer in harmony, this has a negative impact on the stability of the grid voltage and grid frequency.
- electrical consumers are, for example, vehicles with an electrical Energypei cher during a charging process.
- a ripple control signal and a corresponding device can be used to completely separate vehicles from the respective voltage network during a charging process, if the electrical energy consumed by consumers is greater than the electrical energy made available by the power grid.
- a charging station with a power rating of over 11 kW is installed, which is combined with a contactor and switches off the vehicle completely in the event of a network overload by a ripple control signal from the supply network operator.
- the present invention is based on the object of specifying a method for operating a charging station for vehicles with an electrical energy store which, in comparison with the prior art, enables improved stabilization of the voltage network.
- the present invention is based on the general idea of using the vehicles connected to a charging station during a charging process as a regulatable electrical load for stabilizing the voltage network.
- the method according to the invention for operating a charging station for vehicles with an electrical energy store provides that the charging station is supplied with electrical energy via a multi-phase voltage network.
- the voltage network can be divided into a high-voltage network with voltages above 50 kV and a low-voltage network with voltages below 1 kV. It can be provided that the charging station is supplied with electrical energy via a multi-phase, in particular a three-phase, low-voltage network.
- a line of a three-phase low-voltage network can comprise three phase lines and a neutral conductor, the effective voltage at a nominal mains frequency of 50 Hz between any phase line and the neutral conductor can be 230 V, the effective voltage between any two phase lines can be 400 V.
- the charging station provides several, in particular three, phase lines for the electrical power supply of vehicles, at least one vehicle being supplied with a charging current via a phase line.
- At least one mains voltage is measured which is applied to the phase line which supplies the vehicle with a charging current.
- a comparison is made between the measured mains voltage and a stored nominal voltage range, with an adjustment of the charging current taking place if the measured mains voltage lies outside the stored nominal voltage range.
- the effective value of the mains voltage of the respective phase line can be determined with reference to a neutral conductor.
- the nominal voltage range can be, for example, 230 V ⁇ 10%, preferably 230 V ⁇ 5%, particularly preferably 230 V ⁇ 1%. In this way, the voltage network, in particular a low-voltage network, can advantageously be stabilized on a phase-specific basis.
- the grid frequency can also be measured, compared with a nominal grid frequency range and the charging current adjusted if the measured grid frequency lies outside the stored nominal range.
- phase-specific adjustment of the electrical load so that, for example, an unbalanced load in the voltage network can be compensated for or compensated for.
- Such a phase-specific adjustment is not possible using a ripple control signal.
- consumers, in particular charging vehicles, with a non-overloaded phase lines or phases are connected, in contrast to a shutdown by a ripple control signal control not restricted or switched off.
- the measurement of the mains voltage and / or the comparison with the stored nominal voltage range and / or the adaptation of at least one charging current of a phase line and / or all phase lines takes place continuously, in particular once per second.
- the term continuous can be understood to mean that the method steps to be carried out are carried out at predefined time intervals, in particular at equidistant time intervals. This enables timely stabilization of the voltage network, especially a low-voltage network.
- the charging current can be reduced essentially continuously or in leaps or bounds. In the event of a sudden or gradual reduction in the charging current, predefined and / or stored charging current values can be set.
- At least one charging current of the respective phase line is increased if it follows from the comparison between the respectively measured mains voltage and the stored nominal voltage range that the measured mains voltage is greater than a maximum value of the nominal voltage range.
- the electrical load that is present on the respective phase line can be increased in order to achieve sufficient stability of the voltage network, in particular a low-voltage network.
- the energy made available by the power grid has a volatile course in which there is occasionally an excess supply of electrical energy that is available in a suitable manner electrical consumers that are connected to the power grid must be taken up.
- the charging current can be increased substantially steadily or also suddenly or in steps.
- predefined and / or stored charging current values can be set. It can be provided that a maximum charging current is provided and / or stored, which must not be exceeded in order to prevent the vehicle or the energy storage device from being destroyed.
- phase or phase line L1 the first vehicle being charged for 6 hours, the second vehicle for 3 hours and the third vehicle for 1 hour via the phase line. If it follows from the comparison between the measured mains voltage of phase L1 and the stored nominal voltage range that the measured mains voltage is less than a minimum value of the nominal voltage range, the charging current of the first vehicle is reduced to a minimum value. If the mains voltage does not recover due to this load change, the charging current of the second vehicle is reduced to a minimum value. If the line voltage does not recover due to this load change, the charging current of the third vehicle is reduced to a minimum value.
- no charging currents are made available on a phase line if the measured mains voltage lies outside a stored limit voltage range. It can be provided that the charging process of all vehicles that are connected to this phase line is interrupted. In this way, failure of other consumers due to the insufficient mains voltage can be prevented. In addition, a damage to transformers and / or supply lines can be prevented.
- the limit voltage range can include the nominal voltage range.
- the adjustment of the charging current or the charging currents takes place in 1A steps. This makes it possible to adapt the electrical load to a finer and / or lower level than in the prior art, so that a balance can be established between the electrical energy made available in the voltage network and the electrical energy required by the electrical consumers.
- At least one mains frequency is measured which is applied to at least one phase line, a comparison being made between the measured mains frequency and a stored nominal frequency range, with at least one charging current being adjusted if the measured mains frequency lies outside the nominal frequency range.
- this also enables stabilization of a high-voltage network.
- the measurement of the mains frequency and / or the comparison with the stored nominal frequency range and / or the adaptation at least one nes charging current continuously, in particular once per second.
- the term continuous can be understood to mean that the method steps to be carried out are carried out at predefined time intervals, in particular at equidistant time intervals. This enables prompt stabilization of the voltage network, in particular a high-voltage network.
- At least one charging current of the respective phase line is increased when carrying out the adaptation, if it follows from the comparison between the respectively measured mains frequency and the stored nominal frequency range that the measured mains frequency is greater than a maximum value of the nominal frequency range.
- the respective charging current for the charge of the vehicles can be increased up to a limit value of the load capacity of the low-voltage network and / or up to a limit value of the load capacity of the vehicle or the energy store.
- a lower cut-off frequency value of the cut-off frequency range can be 47.5 Hz.
- the cut-off frequency range can encompass the nominal frequency range.
- the invention relates to a charging station for vehicles with an electrical energy storage's.
- the charging station according to the invention has at least one frequency measuring device and / or at least one voltage measuring device.
- the charging station according to the invention comprises a control device which is designed and / or programmed to carry out the method according to the invention, the frequency measuring device and / or the voltage measuring device being communicating with the control device.
- This charging station can carry out a simultaneous stabilization of the low-voltage and the high-voltage network by carrying out measurements of the network voltage and / or the network frequency, with deviations a setpoint-specific regulation of the charging currents, in particular in accordance with DIN EN 50160, takes place from setpoints and / or setpoint ranges.
