Description

TECHNICAL FIELD The present disclosure relates to a control system for controlling an electric vehicle supply equipment and vehicle charge scheduling. Aspects of the invention relate to a control system for controlling an electric vehicle supply equipment, to an electric vehicle supply equipment, to a method for controlling an electric vehicle supply equipment and to computer readable instructions. BACKGROUND It is known to provide a charger (supply equipment) which can be used to supply charge to an energy store of an electric vehicle to recharge the energy store. Charging may be supplied according to a charging schedule which is stored and accessed by the electric vehicle supply equipment. In some households, there is more than one electric vehicle which can use the electric vehicle supply equipment, and each vehicle may have its own charging schedule. If more than one charging schedule is available, then typically the appropriate one is manually selected, which requires user expertise in understanding which charging schedule is required and the use of any software which allows the user to select the desired charging schedule as well as being open to user error in selecting the incorrect charging schedule. It is an aim of the present invention to address one or more of the disadvantages associated with the prior art. SUMMARY OF THE INVENTION Aspects and embodiments of the invention provide an a control system for controlling an electric vehicle supply equipment, to an electric vehicle supply equipment, to a method for controlling an electric vehicle supply equipment and to computer readable instructions as claimed in the appended claims According to an aspect of the present invention there is provided a control system for controlling an electric vehicle supply equipment, the control system comprising one or more processors collectively configured to output a scheduled charging control signal to cause the electric vehicle supply equipment to charge an energy store of an authorised electric vehicle according to a charging schedule of the authorised electric vehicle. Advantageously, an energy store of a vehicle authorised for use with the supply equipment can be charged according to a charging schedule forthat vehicle. According to an aspect of the present invention there is provided a control system for controlling an electric vehicle supply equipment, the control system comprising one or more processors collectively configured to: receive a charging cable connection signal indicative of connection of a charging cable of the electric vehicle supply equipment to a charging port of an authorised electric vehicle; retrieve, in dependence on receipt of the charging cable connection signal, a stored charging schedule for the authorised electric vehicle; and output a scheduled charging control signal to cause the electric vehicle supply equipment to charge an energy store of the authorised electric vehicle according to the charging schedule. Advantageously, simply on connection of the charging cable to the authorised vehicle, an energy store of the authorised vehicle can be charged according to a charging schedule forthat authorised vehicle. The delivery of charge is therefore secure due to provision of the charging schedule for the authorised vehicle, and tailored for the specific vehicle through recognition of the vehicle as being an authorised vehicle. The control system may comprise one or more controllers collectively comprising at least one electronic processor having an electrical input for receiving an input signal; and at least one memory device electrically coupled to the at least one electronic processor and having instructions stored therein; and wherein the at least one electronic processor is configured to access the at least one memory device and execute the instructions thereon so as to: receive a charging cable connection signal indicative of connection of a charging cable of the electric vehicle supply equipment to a charging port of an authorised electric vehicle; retrieve, in dependence on receipt of the charging cable connection signal, a stored charging schedule for the authorised electric vehicle; and output a scheduled charging control signal to cause the electric vehicle supply equipment to charge an energy store of the authorised electric vehicle according to the charging schedule. Advantageously, an energy store of the authorised vehicle can be charged according to a charging schedule forthat authorised vehicle under control of the control system. The delivery of charge is therefore secure due to provision of the charging schedule for the authorised vehicle, and tailored for the specific vehicle through recognition of the vehicle as being an authorised vehicle. The control system may be configured to, priorto receipt of the charging cable connection signal: receive, over a wireless connection, an authorised vehicle identification signal indicative of the presence of the authorised electric vehicle in operational proximity to the electric vehicle supply equipment; determine, in dependence on receipt of the authorised vehicle identification signal, the authorised vehicle is authorised to be supplied with charge from the electric vehicle supply equipment. Advantageously, on approach of the vehicle to the electric vehicle supply equipment, through wireless detection, a vehicle can be authorised once it is in operational proximity to the supply equipment e.g. close enough for the charging cable of the supply equipment to be connected to the vehicle. Thus the driver or a user of the vehicle need not provide any conscious inputs and the control system of the supply equipment can automatically determine that the vehicle is authorised and can determine a charging schedule forthat vehicle and supply charge according to that schedule once the charging cable is connected to the vehicle. The control system may be configured to authorise the electric vehicle in operational proximity to the electric vehicle supply equipment by: receiving, over the wireless connection, a vehicle identifier of a vehicle in operational proximity to the electric vehicle supply equipment; comparing the received vehicle identifier to a stored list of authorised vehicle identifiers; and if the received vehicle identifier matches one of the stored list of authorised vehicle identifiers, determining the vehicle is an authorised vehicle. Advantageously, the vehicle can automatically provide an identifier over wireless connection to the supply equipment which is used to determine whether it is authorised, and can therefore receive charge according to store charging schedule. The electric vehicle supply equipment may comprise a WiFi sniffing module configured to receive the authorised vehicle identification signal over the wireless connection and transmit the authorised vehicle identification signal to the control system. Advantageously, the vehicle can be automatically detected through Wi-Fi sniffing, and information about the vehicle, such as a vehicle identifier, can automatically be provided to the control system without requiring any explicit input from the driver of the user. The control system may be configured to: determine, in dependence on the received authorised vehicle identification signal, an identity of the authorised vehicle; retrieve, in dependence on receipt of the charging cable connection signal and the identity of the authorised vehicle, the stored charging schedule of the identified authorised vehicle from a schedule storage means; and output the scheduled charging control signal to cause the electric vehicle supply equipment to charge the energy store of the identified authorised electric vehicle according to the charging schedule of the identified authorised vehicle. Advantageously, the electric vehicle supply equipment automatically determines, for the specific vehicle it is proximal to, a charging schedule for that specific vehicle and can perform charging according to schedule automatically when the charging cable is connected to the vehicle. The authorised vehicle identification signal transmitted by the authorised vehicle may comprise a portion of a Vehicle Identification Number, VIN, of the authorised vehicle. Advantageously, the charging schedule may be retrieved in dependence on receipt of a unique vehicle identifier, i.e. at least part of the VIN, and the control system can control the electric vehicle supply equipment to provide charging according to the vehicle specific charging schedule. The control system may be configured to, prior to receipt of the charging cable connection signal: receive, over a wireless connection, an unauthorised vehicle identification signal indicative of the presence of an unauthorised electric vehicle in operational proximity to the electric vehicle supply equipment; determine, in dependence on receipt of the unauthorised vehicle identification signal, the unauthorised vehicle is not authorised to be supplied with charge from the electric vehicle supply equipment; and inhibit the provision of charge from the electric vehicle supply equipment to the unauthorised vehicle. Advantageously, a vehicle which is not authorised cannot be charged using the supply equipment, thereby enhancing security. The control system may be further configured to: output a user authorisation signal to a user authorisation device, the user authorisation signal indicative of a request for user authorisation of the unauthorised electric vehicle in operational proximity to the electric vehicle supply equipment; receive, in dependence on a user authorisation input made in response to the request for user authorisation, a user authorisation signal indicative of authorisation of the unauthorised electric vehicle in operational proximity to the electric vehicle supply equipment; and determine the unauthorised electric vehicle is now an authorised electric vehicle. Advantageously, in situations in which a vehicle is not automatically be detected as being authorised even though it is authorised (forexample, an error in WiFi communication between the vehicle and supply equipment may occur, or the vehicle may be new to the supply charger but still be authorised for use, e.g. a newly purchased vehicle or an expected visitor’s vehicle). A user can authorise that the vehicle can receive charging from the supply equipment and override the initial inhibition of supply of power. The user authorisation device may comprise one or more of the electric vehicle supply equipment, the authorised vehicle, and a personal electronic device of the user. Advantageously, the user may provide the authorisation input at the supply equipment, via their personal device, for example through an app linked to the supply equipment, or from the vehicle (e.g. a human machine interface (HMI) of the vehicle). The control system may be further configured to, in dependence on receipt of the user authorisation signal, store a vehicle identifier of the now authorised electric vehicle in a stored list of authorised vehicle identifiers. Advantageously, the newly authorised vehicle can be stored as an authorised vehicle so future manual authorisation is not required. The unauthorised vehicle identification signal transmitted by the unauthorised vehicle may comprises a portion of a Vehicle Identification Number, VIN, of the authorised vehicle. The operational proximity of the authorised vehicle to the electric vehicle supply equipment may be a WiFi transmission range proximity within which WiFi signalling can be transmitted from the authorised vehicle to the electric vehicle supply equipment. The operational proximity of the authorised vehicle to the electric vehicle supply equipment may be an electric vehicle supply equipment charging cable length proximity within which the charging cable can be connected to a charging port of the authorised vehicle. Advantageously, the vehicle can automatically be detected to be within appropriate range for functionality of the supply equipment to be activated because the vehicle is in meaningful range of the supply equipment, that is it is close enough to be communicate for authorisation and charged by the supply equipment In an aspect there is provided an electric vehicle supply equipment comprising any control system disclosed herein. In an aspect of the present invention, there is provided a system comprising any electric vehicle supply equipment disclosed herein and an authorised vehicle configured to transmit, to the electric vehicle supply equipment, the authorised vehicle identification signal indicative of the presence of the authorised vehicle in operational proximity to the electric vehicle supply equipment. In an aspect there is provided a computer-implemented method for controlling an electric vehicle supply equipment, the method comprising: receiving a charging cable connection signal indicative of connection of a charging cable of the electric vehicle supply equipment to a charging port of an authorised electric vehicle; retrieving, in dependence on receipt of the charging cable connection signal, a stored charging schedule for the authorised electric vehicle; and outputting a scheduled charging control signal to cause the electric vehicle supply equipment to charge an energy store of the authorised electric vehicle according to the charging schedule. In an aspect there are provided computer readable instructions which, when executed by one or more processors, cause the one or more processors to perform any method disclosed herein. According to an aspect there is provided a control system for controlling an electric vehicle supply equipment, the control system comprising one or more processors collectively configured to: generate a dynamic charging schedule of the authorised electric vehicle in dependence on a target state of charge of an electric vehicle and a target charge time by which an energy store of the electric vehicle is to store the target state of charge; and output a charging control signal to cause the electric vehicle supply equipment to charge an energy store of the authorised electric vehicle according to the dynamic charging schedule. Advantageously, a charging schedule can be generated according to the charge needs of the vehicle and a time by which the vehicle energy store is to have that charge, without relying on a pre-stored charging schedule and which may be generated adaptively according to the current context. In an aspect there is provided a control system for controlling an electric vehicle supply equipment, the control system comprising one or more processors collectively configured to: receive an authorised vehicle identification signal indicative of the presence of the authorised electric vehicle in operational proximity to the electric vehicle supply equipment; receive charge request signalling indicative of a target state of charge of the authorised electric vehicle and a target charge time by which an energy store of the authorised electric vehicle is to store the target state of charge; generate a dynamic charging schedule of the authorised electric vehicle in dependence on the target state of charge and the target charge time; and output a charging control signal to cause the electric vehicle supply equipment to charge an energy store of the authorised electric vehicle according to the dynamic charging schedule. Advantageously, a charging schedule can be generated for an energy store of an authorised vehicle to be charged, according to the charge needs of that vehicle and a time by which that vehicle energy store is to have that charge, and charge can be supplied to that vehicle according to the generated charging schedule. The authorised vehicle identification signal may be received from the authorised vehicle over a wireless connection. Advantageously the vehicle may be identified, and the charging schedule generated, on approach or proximity of the vehicle to the electric vehicle supply equipment without necessarily connecting the charging cable of the electric vehicle supply equipment to the vehicle, so the charging schedule may be generated ready for use for an authorised vehicle. The control system may be configured to generate the dynamic charging schedule further in dependence on one or more of: an electricity supply tariff associated with the supply of electrical power to the electric vehicle supply equipment; and an availability of solar-generated energy, the solar-generated energy generated by a solar panel apparatus associated with the electric vehicle supply equipment. The solar panel apparatus is associated with the electric vehicle supply equipment by being located with (i.e. at the same property as) the electric vehicle supply equipment, and connected to (i.e. to provide solar-generated electrical power to) the electric vehicle supply equipment. Therefore, electrical energy supplied using solar-generated energy from the vehicle charging location (e.g. the user’s home) means the charging process uses less mains-supplied electricity, for improved sustainability and improved energy management for the user. Advantageously, the charging schedule may be generated taking into account the energy supply tariff of supplying the electric vehicle supply equipment with energy (e.g. a cost tariff, for example higher cost at on-peak demand times and lower cost at off-peak demand times, or an environmental I sustainability tariff whereby energy may be available to be provided to the electric vehicle supply equipment which originates from renewable, or from nonrenewable, energy sources). Advantageously, the charging schedule may be generated considering the availability of solar-generated (i.e. renewable) energy. In other examples, other renewable energy sources to solar energy (e.g. wind power, geothermal power, tidal power) may be used. For example, if electricity can be supplied by a renewable energy source rather than a non-renewable energy source, then the charging schedule may be generated to include electrical charge supply using renewably sourced energy where possible. The control system may be configured to generate the dynamic charging schedule in dependence on the electricity supply tariff by scheduling the supply of electrical charge from the electric vehicle supply equipment to the energy store of the authorised electric vehicle according to the lowest electricity supply tariff. A low “cost” tariff may be a cheaper off-peak price rather than a more expensive on-peak price. A low “environmental” I “sustainable” tariff may be electrical energy sourced from renewable energy means (e.g. solar power) rather than non-renewable energy means (e.g. fossil fuels). Advantageously, the charging schedule may be generated to provide a lowest available tariff - in terms of using an off-peak (lower) cost tariff this advantageously uses off-peak electricity; in terms of using a renewable energy source tariff (having lower environmental cost) this advantageously helps to reduce harmful environmental impact by using renewable / sustainable energy sources. The control system may be configured to, in a period following generation of the dynamic charging schedule: receive a solar-generated energy availability signal indicative of a detected increase in availability of solargenerated energy since generation of the dynamic charging schedule; re-generate the dynamic charging schedule of the authorised electric vehicle in dependence on the increase in availability of solar-generated energy to obtain an updated dynamic charging schedule; and output a further charging control signal to cause the electric vehicle supply equipment to charge the energy store of the authorised electric vehicle according to the updated dynamic charging schedule. Advantageously, the generated schedule may be dynamically adapted to benefit from an increased availability of solar-generated (renewable) energy source at the vehicle location with which the energy store of the vehicle can be charged and, for example, reduce the reliance on mains electricity supply. In the period following generation of the dynamic charging schedule, the electric vehicle supply equipment may supply the authorised electric vehicle with charge according to the dynamic charging schedule. The control system may be configured to re-generate the dynamic charging schedule to obtain the updated dynamic charging schedule by one or more of: increasing a proportion of electrical charge obtained as solargenerated energy to be provided by the electric vehicle supply equipment to the energy store of the authorised electric vehicle according to the dynamic charging schedule; increasing a proportion of electrical charge obtained at a low electricity supply tariff to be provided by the electric vehicle supply equipment to the energy store of the authorised electric vehicle according to the dynamic charging schedule; and decreasing a proportion of electrical charge at a high electricity supply tariff to be provided by the electric vehicle supply equipment to the energy store of the authorised electric vehicle according to the dynamic charging schedule. Advantageously, charging may be performed according to a dynamic schedule which can change to increased, where available, the amount of electricity supplied by renewable means (e.g. solar energy) and / or at an improved tariff (e.g. cost tariff and / or environmental impact tariff). The control system may be configured to receive a charging cable connection signal indicative of connection of a charging cable of the electric vehicle supply equipment to a charging port of an authorised electric vehicle; and generate the dynamic charging schedule in dependence on receipt of the charging cable connection signal. Advantageously, the charging schedule is determined once a physical connection is detected of the charging cable with the vehicle, so computational effort is not expended in determining a schedule unless the vehicle is physically connected for charging. That is, in response to the connection of the cable, indicating that the vehicle is to receive charge, (as opposed to a vehicle parking close to the supply equipment but which is not necessarily to be charged), the charging schedule is generated. The control system may be configured to determine, in dependence on receipt of the authorised vehicle identification signal, the authorised vehicle is authorised to be supplied with charge from the electric vehicle supply equipment. Advantageously, the charging schedule is determined on detection of an authorised vehicle, e.g. the user’s vehicle registered to the same address as the supply equipment, so that charging can commence according to the generated schedule on connection of the vehicle to the supply equipment by the charging cable. The control system may be configured to transmit, to an external user apparatus, schedule signalling indicative of the generated dynamic charging schedule for output by the external user apparatus. The external user apparatus may comprise one or more of: a portable electronic device, a smartphone, a smart watch, and a personal computer. Advantageously, the user may be alerted to generated and / or updating of the charging schedule. In an aspect there is provided a computer-implemented method for controlling an electric vehicle supply equipment, the method comprising: receiving an authorised vehicle identification signal indicative of the presence of the authorised electric vehicle in operational proximity to the electric vehicle supply equipment; receiving charge request signalling indicative of a target state of charge of the authorised electric vehicle and a target charge time by which an energy store of the authorised electric vehicle is to store the target state of charge; generating a dynamic charging schedule of the authorised electric vehicle in dependence on the target state of charge and the target charge time; and outputting a charging control signal to cause the electric vehicle supply equipment to charge an energy store of the authorised electric vehicle according to the dynamic charging schedule.

DETAILED DESCRIPTION It is known to provide an electric vehicle supply equipment (or simply a “supply equipment”, which may also be called a “charger” or “home charger”) which can be used to supply charge to an energy store of an electric vehicle to recharge the energy store. The supply equipment may be understood to be an apparatus which can be connected to a vehicle (and the electrical energy storage of that vehicle) for the provision of charge from the supply equipment to the vehicle, to recharge the electrical energy storage. Discussion here in supply of electrical charge to the vehicle should be understood as a supply of electrical charge of an energy storage means of the vehicle e.g. a rechargeable battery. The vehicle may be a battery electric vehicle or a hybrid vehicle, for example. Charging may be supplied according to a charging schedule which is stored and accessed by the electric vehicle supply equipment. In some households, there is more than one electric vehicle which can use the electric vehicle supply equipment, and each vehicle may have its own charging schedule. If more than one charging schedule is available, then the appropriate one currently is manually selected, which requires user expertise in understanding which charging schedule is required and the use of any software which allows the user to select the desired charging schedule. Examples disclosed herein allow the electric vehicle supply equipment to automatically identify the vehicle which is proximal to the electric vehicle supply equipment and / or which is connected to the electric vehicle supply equipment, and then automatically apply a preconfigured charging schedule forthat particular vehicle. The vehicle may be identified in a variety of ways, for example using wireless or wired communication between the electric vehicle supply equipment and vehicle. When a vehicle is physically connected to an electric vehicle supply equipment to allow for the supply of charge, then examples disclosed herein provide for the supply equipment to automatically identify the vehicle using a wired or wireless communication method. For example, fora wired communication, the electric vehicle supply equipment may use the standard ISO 115118-2 to obtain a media access control (MAC) address from the vehicle. This approach can be used with any vehicle which supports the ISO 115118-2 standard using a static MAC address as an electric vehicle identifier (EVCCID). For wireless communication (with or without wired connection being present between the vehicle and supply equipment), the supply equipment may identify a vehicle by detecting its Wi-Fi service set identifier (SSID) or other Wi-Fi communicable unique identifier (for example an SSID containing the last portion of the vehicle’s VIN). In some examples the vehicle may be identified by the unique identifier being transmitted over a dedicated secure wireless connection between the electric vehicle supply equipment and the vehicle. Whichever method is used to identify the vehicle, then the appropriate vehicle identifier can be transmitted to the electric vehicle supply equipment (and for example to a back office software platform for the supply equipment) and a preconfigured charging schedule associated with that specific identifier can be selected and installed on the home charger will schedule charging according to charging schedule. In some examples the charging schedule can be removed from the electric vehicle supply equipment when the vehicle is disconnected. Examples disclosed herein allow the electric vehicle supply equipment to automatically identify the vehicle which is proximal to the electric vehicle supply equipment and / or which is connected to the electric vehicle supply equipment, and receive an indication of a desired target state of charge which the vehicle wants to have, and a target charge time by which the desired state of charge is to be implemented. A charging schedule for the vehicle may then be generated based on the desired target stage of charge and target charge time of the authorised vehicle. In some examples, the generated charging schedule may be considered to be dynamic, in that if a change of situation occurs, the generated charging schedule may be dynamically adjusted to account for the change of situation to more appropriately provide charge to the energy store of the vehicle. An example is of the availability of solar generated electrical power availability increasing after generation of the charging schedule. The schedule may be adapted to increase the amount of electrical charge provided to the vehicle from solar generation (and thus decrease the amount of electrical charge provided to the vehicle from the mains electrical grid) which may improve the use of renewable energy sources for providing electrical charge (and in some examples may provide a cost saving to the supply equipment user). Figure 1 shows an electric vehicle supply equipment 200 according to embodiments of the invention. The electric vehicle supply equipment 200 comprises a control system 100 as discussed in relation to Figure 2. The electric vehicle supply equipment 200 comprises a charging cable 202 which can be connected, by a charging gun 204 on the charging cable 202, to an electric vehicle, and used to provide electrical charge from the electric vehicle supply equipment 200 to the vehicle (i.e. to a rechargeable energy store of the vehicle). In some examples the electric vehicle supply equipment 200 may comprise an output device 206 such as a display screen or visual indicator to indicate information to a user. With reference to Figure 2, there is illustrated a control system 100 for an electric vehicle supply equipment 200. The control system 100 comprises one or more controller 110. In some examples, the control system 100 is configured to receive a charging cable connection signal 165 which is indicative of connection of a charging cable 202 of an electric vehicle supply equipment 200 to a charging port of an authorised electric vehicle. The charging cable connection signal 165 may be provided, for example, by a sensor 160 of the charging gun 204. The control system 100 is configured to retrieve, in dependence on receipt of the charging cable connection signal 165, a stored charging schedule for the authorised electric vehicle. The control system 100 is configured to then output a scheduled charging control signal 155 to cause the electric vehicle supply equipment 200 to charge an energy store of the authorised electric vehicle according to the charging schedule. In some examples, the control system 100 is configured to receive an authorised vehicle identification signal 165 which is indicative of the presence of the authorised electric vehicle 50 in operational proximity to the electric vehicle supply equipment 200. The control system 100 is also configured to receive charge request signalling indicative of a target state of charge of the authorised electric vehicle and a target charge time by which an energy store of the authorised electric vehicle is to store the target state of charge. The control system 100 is configured to generate a dynamic charging schedule of the authorised electric vehicle in dependence on the target state of charge and the target charge time; and output a charging control signal 155 to cause the electric vehicle supply equipment 200 to charge an energy store of the authorised electric vehicle according to the dynamic charging schedule. The control system 100 as illustrated in Figure 2 comprises one controller 110, although it will be appreciated that this is merely illustrative. The controller 110 comprises processing means 120 and memory means 130. The processing means 120 may be one or more electronic processing device 120 which operably executes computer-readable instructions. The memory means 130 may be one or more memory device 130. The memory means 130 is electrically coupled to the processing means 120. The memory means 130 is configured to store instructions, and the processing means 120 is configured to access the memory means 130 and execute the instructions stored thereon. The controller 110 comprises an input means 140 and an output means 150. The input means 140 may comprise an electrical input 140 of the controller 110. The output means 150 may comprise an electrical output 150 of the controller 110. In some examples, the input 140 is arranged to receive a charging cable connection signal 165, for example in response to detection of connection of a charging cable 202 of the electric vehicle supply equipment 200 to a vehicle charging port. The charging cable connection signal 165 is an electrical signal which is indicative of connection of a charging cable of the electric vehicle supply equipment to a charging port of an authorised electric vehicle. The controller 110 is configured to retrieve a stored charging schedule for the authorised electric vehicle in dependence on receipt of the charging cable connection signal. The output 150 is arranged to output a scheduled charging control signal 155 for controlling the electric vehicle supply equipment 200 and cause it to charge an energy store of the authorised electric vehicle according to the charging schedule. An energy store (e.g. battery) of the authorised vehicle can be charged according to a charging schedule forthat authorised vehicle, under control of the control system. The provision of charge is secure due to the charging cable connection signal being received following connection by an authorised vehicle, indicating that the vehicle is authorised to receive charge from the supply equipment. The charging schedule for the specific authorised vehicle can then be retrieved and the vehicle energy store can be charged according to the schedule. Unauthorised vehicles cannot receive charge from the supply equipment unless some additional authorisation is specifically provided. In some examples, the input 140 is configured to receive an authorised vehicle identification signal 165 which is indicative of the presence of the authorised electric vehicle in operational proximity to the electric vehicle supply equipment 200. The input 140 is also, in this example, configured to receive charge request signalling indicative of a target state of charge of the authorised electric vehicle, and to receive a target charge time by which an energy store of the authorised electric vehicle is to store the target state of charge. The controller 110 can generate a dynamic charging schedule of the authorised electric vehicle in dependence on the target state of charge and the target charge time. The output 150 can output a charging control signal 155 to cause the electric vehicle supply equipment 200 to charge an energy store of the authorised electric vehicle according to the dynamic charging schedule. Advantageously, a charging schedule can be generated by the controller 110 according to the charge needs of the vehicle and a time by which the vehicle energy store is to have that charge, without relying on a pre-stored charging schedule and which may be generated adaptively according to the current context. Figure 3A shows a flow chart of a computer-implemented method 300 which may be performed by the control system 100 of Figures 1 and 2 for controlling an electric vehicle supply equipment according to embodiments of the invention. The method 300 is a method of controlling an electric vehicle supply equipment 200. The method 300 may be performed by the control system 100 illustrated in Figure 2. In particular, the memory 130 may comprise computer-readable instructions which, when executed by the processor 120, perform the method 300 according to an embodiment of the invention. The method 300 comprises receiving 302 a charging cable connection signal 310 indicative of connection of a charging cable of the electric vehicle supply equipment to a charging port of an authorised electric vehicle. The method 300 comprises retrieving 304 in dependence on receipt of the charging cable connection signal 310, a stored charging schedule for the authorised electric vehicle. The method 300 comprises outputting 306 a scheduled charging control signal 320 to cause the electric vehicle supply equipment 200 to charge an energy store of the authorised electric vehicle according to the charging schedule. Figure 3B shows a flow chart of a computer-implemented method 350 which may be performed by the control system 100 of Figures 1 and 2 for controlling an electric vehicle supply equipment 200 according to embodiments of the invention. The method 350 is a method of controlling an electric vehicle supply equipment 200. The method 350 may be performed by the control system 100 illustrated in Figure 2. In particular, the memory 130 may comprise computer-readable instructions which, when executed by the processor 120, perform the method 300 according to an embodiment of the invention. The method 350 comprises, prior to receipt of the charging cable connection signal 310: receiving 352, over a wireless connection, an authorised vehicle identification signal 360 indicative of the presence of the authorised electric vehicle in operational proximity to the electric vehicle supply equipment. The method 350 comprises determining 354, in dependence on receipt of the authorised vehicle identification signal 360, the authorised vehicle is authorised to be supplied with charge from the electric vehicle supply equipment. The method 350 may comprise outputting 356 an authorisation signal 370 indicative of the vehicle being authorised to receive charge from the supply equipment 200. Advantageously, on approach of the vehicle to the electric vehicle supply equipment 200, through wireless detection, the vehicle can be authorised once it is in operational proximity to the supply equipment 200 e.g. close enough for the charging cable 202 of the supply equipment 200 to be connected to the vehicle. Thus the driver or a user of the vehicle need not provide any conscious inputs, and the control system 100 of the supply equipment 200 can automatically determine that the vehicle is authorised and can determine a charging schedule for that vehicle and supply charge according to that schedule once the charging cable is connected to the vehicle. Operational proximity of the authorised vehicle 50 to the electric vehicle supply equipment 200 may be understood to be a WiFi transmission range proximity within which WiFi signalling can be transmitted from the authorised vehicle 50 to the electric vehicle supply equipment 200. This may be considered an operational proximity because WiFi communications can take place between the electric vehicle supply equipment 200 and a WiFi communication module of the vehicle 50, for example to communicate a vehicle identifier from the vehicle to the supply equipment. Operational proximity of the authorised vehicle 50 to the electric vehicle supply equipment 200 may be understood to be an electric vehicle supply equipment charging cable length proximity within which the charging cable 202 can be connected to a charging port of the authorised vehicle 50. This may be considered an operational proximity because within this distance, the vehicle 50 can be operationally connected to the supply equipment via the charging cable of the supply equipment so the vehicle can receive charge from the supply equipment. The operational proximity of the authorised vehicle to the electric vehicle supply equipment may be understood to be the lesser of these two factors. The operational proximity of the authorised vehicle to the electric vehicle supply equipment may in other examples be determined using geofencing, such that when the vehicle is detected to be located within a predetermined geofence perimeter, it is deemed to be within operational proximity (e.g. within a 10 m radius of the supply equipment 200). The operational proximity of the authorised vehicle to the electric vehicle supply equipment may in other examples be determined using Bluetooth, such that when the vehicle is detected to be located within Bluetooth communication range of the supply equipment (or other Bluetooth communication device located with the supply equipment, or for example in the house where the supply equipment is located), the vehicle is deemed to be within operational proximity (e.g. within a 10 m radius of the supply equipment 200). Advantageously, the approach of a vehicle within meaningful operational distance from the supply equipment (e.g. communication range and / or charging cable connection distance) triggers the provision of functionality for the authorised vehicle. Example processes will be discussed in more detail with reference to Figures 4 and 5. Figure 4 shows a process which control systems 100 disclosed herein are configured to perform for controlling an electric vehicle supply equipment 200 according to embodiments of the invention. Figure 4 shows a vehicle 50 which is able to wirelessly communicate with a WiFi module 402 of the electric vehicle supply equipment 200 when in WiFi range of the WiFi module 402. Also shown is an authorisation list storage means 404 which the control system 100 may communicate with and which has stored therein information about one or more authorised vehicles which are authorised to use the functionality of the electrical vehicle supply equipment 200. As per Figure 3B, prior to receipt of the charging cable connection signal 310, the control system may receive an authorised vehicle identification signal 360 over the wireless connection 500 indicative of the presence of the authorised electric vehicle 50 in operational proximity to the electric vehicle supply equipment 200, and determine the authorised vehicle is authorised to be supplied with charge from the electric vehicle supply equipment 200 in dependence on receipt of the authorised vehicle identification signal 360. The control system 100 may be configured to authorise the electric vehicle in operational proximity to the electric vehicle supply equipment 200 by receiving, over the wireless connection 500, a vehicle identifier 360 of a vehicle 50 in operational proximity to the electric vehicle supply equipment, comparing the received vehicle identifier 360 to a stored list of authorised vehicle identifiers (e.g. stored in the authorisation list storage means 404). If the received vehicle identifier 360 matches one of the stored list of authorised vehicle identifiers, the control system 100 may determine the vehicle 50 is an authorised vehicle. Advantageously, the vehicle can automatically provide an identifier over wireless connection 50 to the supply equipment 200 which is used to determine whether it is authorised, and can therefore receive charge according to store charging schedule. The control system 100 may be configured to: determine, in dependence on the (wirelessly) received authorised vehicle identification signal 360, an identity of the authorised vehicle 50. The control system 100 may then retrieve, in dependence on receipt of the charging cable connection signal and the identity of the authorised vehicle, the stored charging schedule of the identified authorised vehicle from a schedule storage means 510, and output the scheduled charging control signal to cause the electric vehicle supply equipment 200 to charge the energy store of the identified authorised electric vehicle 50 according to the charging schedule of the identified authorised vehicle 50. Advantageously, the electric vehicle supply equipment automatically determines, for the specific vehicle 50 it is proximal to, a charging schedule for that specific vehicle and can perform charging according to schedule automatically when the charging cable 202 is connected to the vehicle 50. The authorised vehicle identification signal 360 transmitted by the authorised vehicle 50 may comprise a portion of a Vehicle Identification Number, VIN, of the authorised vehicle 50. Advantageously, the vehicle 50 can be automatically detected and identified via the provision of a unique immutable identifier, the VIN code portion, and comparison of the transmitted authorised vehicle identification signal 360 with stored authorised vehicle identification information stored in the authorisation list storage means 404. Figure 4 shows a process which control systems 100 disclosed herein may be configured to perform for controlling an electric vehicle supply equipment 200. In this example, the supply equipment 200 includes a power provision control module 504 which is configured to control the provision of electric charge to the connected vehicle 50. Once the vehicle 50 is physically connected to the supply equipment 200 by the charging cable 502 of the supply equipment 200 a verification of authorisation may be performed. In this example, following connection of the vehicle 50 to the charging cable 502, the control system may perform an authorisation check 506. For example, this authorisation check 506 may relate to the provision of electrical power to the vehicle, since it takes place after connecting the vehicle 50 to the charging cable 502. In this example, the authorisation check 506 may determine if the service set identifier (SSID) (a wireless network identification) of the vehicle is detected, and whether the SSID is in a local authorisation list 404. If the SSID is in the local authorisation list 404, the control system 100 may retrieve a charging schedule 508 for the identified vehicle. It may retrieve the charging schedule 508 by transmitting the vehicle SSID to a schedule storage means 510 which returns the charging schedule for the identified vehicle from the schedule storage means 510. If the SSID is not in the local authorisation list 404, or it cannot be located in the authorisation list 404, the control system 100 may send a response message that authorisation has been rejected 514. The control system may then await authorisation 512 following notifying the user that automatic authorisation has been rejected 514, which then allows for schedule retrieval 508 and subsequent charging according to the schedule retrieved from the schedule storage means 510. That is, the control system 100 may be configured to, prior to receipt of the charging cable connection signal, receive an unauthorised vehicle identification signal over a wireless connection 50 which is indicative of the presence of an unauthorised electric vehicle in operational proximity to the electric vehicle supply equipment. The control system 100 may then determine, in dependence on receipt of the unauthorised vehicle identification signal, that the unauthorised vehicle is not authorised to be supplied with charge from the electric vehicle supply equipment, and inhibit the provision of charge from the electric vehicle supply equipment 200 to the unauthorised vehicle. Manual authorisation may then be provided if possible. Advantageously, a vehicle which is not authorised cannot be charged using the supply equipment, thereby enhancing security. The control system 100 may request 516 a userto authorise the retrieval of a charging schedule for the vehicle, which the user may be able to provide via an application on a personal electronic device in communication with the control system 100, or via the supply equipment 200 if there is a suitable user interface for entering authorisation information. If the user does not provide authorisation the process ends 408 without schedule retrieval or charging. If the user does provide authorisation, then the SSID for the newly authorised vehicle may be added 518 to the authorisation list 404, then the control system awaits authorisation 512 to cause the charging schedule to be retrieved 508. That is, in order to obtain authorisation from a user to retrieve a charging schedule for a so-far unauthorised vehicle, in some examples, the control system 100 may be configured to output a user authorisation signal to a user authorisation device. The user authorisation device may comprise one or more of the electric vehicle supply equipment, the authorised vehicle, and a personal electronic device of the user. Advantageously, the user may provide the authorisation input at the supply equipment, via their personal device, for example through an app linked to the supply equipment, or from the vehicle (e.g. a HMI of the vehicle). The user authorisation signal is indicative of a request 516 for user authorisation of the unauthorised electric vehicle in operational proximity to the electric vehicle supply equipment 200. The control system 100 may receive, in dependence on a user authorisation input made in response to the request for user authorisation, a user authorisation signal indicative of authorisation of the unauthorised electric vehicle in operational proximity to the electric vehicle supply equipment, and determine the unauthorised electric vehicle is now an authorised electric vehicle 50. Advantageously, in situations in which a vehicle 50 is not automatically detected as being authorised even though it is authorised (for example, an error in WiFi communication between the vehicle 50 and supply equipment 200 may occur, or the vehicle may be new to the supply charger but still be authorised for use, e.g. a newly purchased vehicle or an expected visitor’s vehicle), a user can authorise that the vehicle can receive charging from the supply equipment and override the initial inhibition of supply of power. The control system 100 may be further configured to, in dependence on receipt of the user authorisation signal 516, store a vehicle identifier 518 of the now authorised electric vehicle in a stored list of authorised vehicle identifiers. Advantageously, the newly authorised vehicle can be stored as an authorised vehicle so future manual authorisation is not required. The unauthorised vehicle identification signal transmitted by the unauthorised vehicle may comprise a portion of a Vehicle Identification Number, VIN, of the authorised vehicle. Figure 5 illustrates a system 600 of a supply equipment 200 and a vehicle 50 according to embodiments of the invention. The vehicle 50 may wirelessly communicate 602 with the supply equipment 200 (i.e. a wireless communications module of the supply equipment 200). The charging cable 604 may in some examples provide communications functionality between the vehicle 50 and the supply equipment 200. In some examples the connection of the charging cable 604 to the vehicle 50 may be detected and used for authorisation to perform some functionality such as providing charge to the vehicle 50 from the supply equipment 200. The system 600 may comprise any electric vehicle supply equipment 200 disclosed herein and an authorised vehicle 50. Figure 6 shows a flow chart showing a further example method 700 which control systems 100 disclosed herein are configured to perform for controlling an electric vehicle supply equipment 200. The method 700 may be performed by a control system 100 for controlling an electric vehicle supply equipment 200. The method 700 shows the control system 100 is configured to receive 702 an authorised vehicle identification signal 710 which is indicative of the presence of the authorised electric vehicle in operational proximity to the electric vehicle supply equipment, as discussed above. The authorised vehicle identification signal 710 may be received from the authorised vehicle over a wireless connection as discussed above. In this way the vehicle 50 may be identified, and the charging schedule generated, on approach or proximity of the vehicle to the electric vehicle supply equipment without necessarily connecting the charging cable of the electric vehicle supply equipment to the vehicle, so the charging schedule may be generated ready for use. Then, charge request signalling 720 is received 704 which is indicative of a target state of charge 722 of the authorised electric vehicle and a target charge time 724 by which an energy store of the authorised electric vehicle is to store the target state of charge. The method 700 then generates 706 a dynamic charging schedule 730 of the authorised electric vehicle in dependence on the target state of charge 722 and the target charge time 724. In some examples, the control system 100 may be configured to receive a charging cable connection signal 310 indicative of connection of a charging cable 604 of the electric vehicle supply equipment 200 to a charging port of the authorised electric vehicle 50; and generate the dynamic charging schedule 730 in dependence on receipt of the charging cable connection signal 310. Advantageously, the charging schedule 730 is determined once a physical connection is detected of the charging cable 604 with the vehicle 50, so computational effort is not expended in determine a schedule 730 unless the vehicle is physically connected for charging. That is, in response to the connection of the cable 604, indicating that the vehicle 50 is to receive charge, (as opposed to a vehicle parking close to the supply equipment but which is not necessarily to be charged), the charging schedule 730 is generated 706. The dynamic charging schedule 730 may be generated further in dependence on an electricity supply tariff associated with the supply of electrical power to the electric vehicle supply equipment. The dynamic charging schedule 730 may be generated further in dependence on an availability of solar-generated energy, the solargenerated energy generated by a solar panel apparatus associated with the electric vehicle supply equipment. The solar panel apparatus may be associated with the electric vehicle supply equipment 200 by being located with and connected to the electric vehicle supply equipment 200 - for example, the electric vehicle supply equipment 200 may be at a user’s home and the home may be fitted with solar panels. Therefore, electrical energy supplied using solar-generated energy from the vehicle charging location (e.g. the user’s home) means the charging process uses less mains-supplied electricity, for improved sustainability and improved usability of a user’s solar-panel-generated electrical power. The charging schedule may be generated considering the energy supply tariff of supplying the electric vehicle supply equipment 200 with energy in some examples, for example, a cost tariff (on-peak or off-peak), or an environmental I sustainability tariff whereby energy is available to be provided to the electric vehicle supply equipment which originates from renewable, or from non-renewable, energy sources. A low “cost” tariff may be a cheaper off-peak price rather than a more expensive on-peak price. A low “environmental” / “sustainable” tariff may be electrical energy sourced from renewable energy means (e.g. solar power) rather than non-renewable energy means (e.g. fossil fuels). Advantageously, the charging schedule may be generated taking into account the availability of cost effective and / or renewable energy sourced electrical energy, and the charging schedule may be generated to include electrical charge supply using renewably sourced energy where possible. A charging control signal 740 is then output 708, which causes the electric vehicle supply equipment 200 to charge an energy store of the authorised electric vehicle 50 according to the dynamic charging schedule 730. Advantageously, a charging schedule 730 can be generated for an authorised vehicle 50 to be charged, according to the charge needs 722 of that vehicle and a time 724 by which that vehicle energy store is to have that charge, and charge can be supplied to that vehicle according to the generated charging schedule. In some examples, the control system 100 may be configured to transmit, to an external user apparatus, schedule signalling 760 indicative of the generated dynamic charging schedule 730 for output by the external user apparatus. The external user apparatus may be a portable electronic device, a smartphone, a smart watch, or a personal computer, for example. For example, when the charging schedule is generated, and / or when the dynamic charging schedule is updated, a user may receive a notification on their personal electronic device to inform them that the charging schedule has changed, so the suer is made aware of how the supply equipment is operating and has confidence that it is operating as desired. The control system may be able to generate the charging schedule and dynamically adapt it to changes in situation, for example, if an increased level of sustainably sourced electrical energy is available to use to charge the vehicle energy store. In some examples, a user may be able to indicate preferences in charging behaviour (e.g. use a low cost tariff; charge between particular times of the day, for example) and the charging schedule may be generated to accommodate the user’s preferences where possible. In some examples the generated charging schedule may be overridden, for example by a user’s input to provide a “boost charge”. Figure 7 shows a flow chart showing a further method 750 which control systems 100 disclosed herein are configured to perform for controlling an electric vehicle supply equipment 200 according to embodiments of the invention. The control system 100 may be configured to, in a period following generation of the dynamic charging schedule: receive 702a a change in energy availability signal 750 indicative of a detected change in energy availability since generation of the dynamic charging schedule. The control system may then re-generate 706a the dynamic charging schedule of the authorised electric vehicle 50 in dependence on the change in energy availability to obtain an updated dynamic charging schedule 730a, and output 708a a further charging control signal 740a to cause the electric vehicle supply equipment 200 to charge the energy store of the authorised electric vehicle 50 according to the updated dynamic charging schedule 730a. In an example of an increase in availability of solar power, Figure 7 may be understood to illustrate, in a period following generation of the dynamic charging schedule 730: receiving 702a a solar-generated energy availability signal 750 indicative of a detected increase in availability of solar-generated energy since generation of the dynamic charging schedule; re-generation 706a of the dynamic charging schedule 730 of the authorised electric vehicle in dependence on the increase in availability of solar-generated energy to obtain an updated dynamic charging schedule 730a; and outputting 708a the further charging control signal 740a to cause the electric vehicle supply equipment 200 to charge the energy store of the authorised electric vehicle 50 according to the updated dynamic charging schedule 730a. Advantageously, the generated schedule 730, 730a may be dynamically adapted to benefit from, for example, an increased availability of solar-generated (renewable) energy at the vehicle location with which the energy store of the vehicle 50 can be charged and, for example, reduce the reliance on mains electricity supply. In the period following generation of the dynamic charging schedule, the electric vehicle supply equipment 200 may supply the authorised electric vehicle 50 with charge according to the dynamic charging schedule 730, 730a. The control system 100 may be configured, for example, to re-generate the dynamic charging schedule 730 to obtain the updated dynamic charging schedule 730a by one or more of: increasing a proportion of electrical charge obtained as solar-generated energy to be provided by the electric vehicle supply equipment 200 to the energy store of the authorised electric vehicle 50 according to the dynamic charging schedule 730a; increasing a proportion of electrical charge obtained at a low electricity supply tariff to be provided by the electric vehicle supply equipment 200 to the energy store of the authorised electric vehicle 50 according to the dynamic charging schedule 730a; and decreasing a proportion of electrical charge at a high electricity supply tariff to be provided by the electric vehicle supply equipment 200 to the energy store of the authorised electric vehicle 50 according to the dynamic charging schedule 730a. Advantageously, charging may be performed according to a dynamic schedule which can change to increased, where available, the amount of electricity supplied by renewable means (e.g. solar energy) and / or at an improved tariff (e.g. cost tariff and / or environmental impact tariff). In some examples, the control system may be configured to transmit, to an external user apparatus, schedule signalling 760a indicative of the updated dynamic charging schedule 730a for output by the external user apparatus. For example, when the charging schedule is generated, and / or when the dynamic charging schedule is updated, a user may receive a notification on their personal electronic device to inform them that the charging schedule has changed. It will be appreciated that various changes and modifications can be made to the present invention without departing from the scope of the present application.
