[0001] SYSTEM ND METHOD FOR CHARGING MULTIPLE ELECTRIC VEHICLES

[0002] RELATED APPLICATIONS

[0003] This application claims the benefit of priority under 35 USC § 119(e) of U.S. Provisional Patent Application No. 63 / 712,550 filed October 28, 2024, and U.S. Provisional Patent Application No. 63 / 697,613 filed September 23, 2024, the contents of which are incorporated herein by reference in their entirety.

[0004] FIELD AND BACKGROUND OF THE INVENTION

[0005] The present invention, in some embodiments thereof, relates to a charging system for charging multiple electric vehicles, preferably, but not exclusively, for direct current (DC) charging of multiple vehicles asynchronously.

[0006] Quick DC chargers for electric vehicles (EV) require very large amounts of power and expensive infrastructure (e.g., very thick underground cables to carry super high currents). This makes it very difficult to charge a large number of cars simultaneously. Additionally, generally, each DC power charger has one or two cables without controllers, therefore whichever vehicle is connected receives maximum power. This means that if a user comes to a charging station and it is already in use, the user must wait with their vehicle until a power supply cable becomes available and then plug the power supply cable into their vehicle and initiate charging (either using a mobile app, user interface, etc.).

[0007] Conventional solutions include setting up a limited number of shared charging stations. However, drivers are often frustrated by having to wait for a station to become available, preferring to charge their electric vehicles while they are at work or asleep at night. Additionally, drivers find it inconvenient to return and move the electric vehicle once charging is complete, in addition, they might go get coffee, do some shopping, see a movie, etc. and return late, wasting the precious time of the charge station.

[0008] In some AC power stations, electric vehicles can connect at the same time, and AC power is distributed to each electric vehicle in turn. Electric vehicles receive AC power, typically 3 -phase or 2-phase and each electric vehicle includes its own individual power supply that converts AC to DC. However, the DC power levels are usually less than 20 kW.

[0009] Simultaneous DC charging for multiple EVs may result in high power demands and / or strain the electrical grid, potentially leading to voltage drops or power outages. Additionally, the distribution of power to multiple charging stations requires a robust and reliable infrastructure, which can be expensive and complex to build. The expense of infrastructure is increased when trying to supply such charge points in a large number of convenient parking locations.

[0010] On the other hand, sequential charging of multiple parked vehicles also leads to significant challenges. While this approach may be more manageable for the grid, it can lead to inefficiencies and longer wait times for drivers. Supplying multiple charging stations or deploying robots to connect and disconnect power cables can be logistically complex and costly.

[0011] The installation of high-current DC cables for fast DC charging at a large number of parking locations, presents significant logistical and technical challenges. These cables are typically thicker and heavier than traditional AC cables due to the need to carry large amounts of current without excessive voltage drop. The weight of a DC cable is influenced by factors such as its cross-sectional area, conductor material, and insulation. A larger cross-sectional area is required to carry higher currents, which increases the cable's weight. The relationship between cable weight, length, and current level is proportional: longer cables and higher currents result in heavier cables.

[0012] The installation of high-current DC cables often involves trenching or underground conduits, which can be disruptive and costly, especially in urban areas. Additionally, the handling and transportation of these heavy cables can pose safety risks. These challenges highlight the need for careful planning and coordination to minimize the imp act of cable installation on the surrounding environment and infrastructure.

[0013] Conventional solutions include setting up a limited number of shared charging stations and / or strict scheduling of access. However, drivers are often frustrated by having to wait for a station to become available, preferring to charge their electric vehicles while they are at work or asleep at night. Additionally, drivers find it inconvenient to return and move the electric vehicle once charging is complete, in addition, they might go get coffee, do some shopping, see a movie, etc. and return late, wasting the precious time of the charge station.

[0014] Alternatively, many charging stations can be set up, with each station connected to the same single energy source. Drivers can plug in their electric vehicles and leave them for an extended period. As energy becomes available, it is allocated to the next station in line. However, this type of infrastructure is very costly.

[0015] In some cases, rather than building expensive and / or limited infrastructure, a conveyer may be used to bring a power bank to a parked car, charge the car and then move to another car. For example, the conveyer may include a robot and / or a person. This may be made difficult because different types of electric vehicles may have charging ports in a different place and / or vehicles can be parked in a different position. In some cases, vehicles may be parked in a way that limits access to the charging port (e.g., two vehicles parked close together). Therefore, it is very difficult for a human or robotic charging attendant to find and reach the various charging ports. Furthermore, some electric vehicles lock automatically when not in use or being charged and there is no standard way to open the charging ports and / or opening the charging port may require using the keys to the vehicle, which is not always possible or desirable.

[0016] Therefore, there is a need for a system which facilitates charging of multiple electric vehicles as charging capacity becomes available.

For example, in method 166, a plurality of vehicles may be charged. Method 166 includes providing 168 a limited power source. The power source may be configured to dynamically adjust its output based on real-time demand and availability, for example, this may facilitate efficient energy distribution. Additionally, or alternatively, the power source may incorporate renewable energy sources such as solar panels or wind turbines to supplement the grid power. The system may also include energy storage solutions like batteries or supercapacitors to store excess energy for later use.

[0145] In some embodiments, a respective electrical power interface is reversibly connected 170 to each vehicle of the plurality of vehicles (e.g., by connecting a power cord to a respective charging port of a vehicle). Optionally, the plurality of vehicles are connected to the plurality electrical power interfaces concurrently. Optionally, each power cord may be equipped with sensors, for example, to detect proper connection and ensure safety during the charging process. Alternatively, or additionally, system may also support wireless charging technologies, allowing vehicles to charge without physical connectors.

[0146] In some embodiments, a connection of the electrical power interface to a power source is established 172. For example, a power source may be connected to each power cord of a plurality of power cords. The connection of the electrical power interface to the power source may be independent of the position of the respective charging port on the vehicle. The system may include a universal adapter that can accommodate various charging port designs and standards, facilitating compatibility with a wide range of EVs. Additionally, the system may feature a self-diagnosis mechanism to detect and troubleshoot connection issues automatically. The power cords may also have built-in surge protection to safeguard the vehicles and the charging station from electrical faults.

[0147] In some embodiments, a charging priority is assigned 174 to each vehicle of said a plurality of vehicles. Power is optionally distributed 176 differentially to each vehicle in accordance with their assigned priority. For example, the system may use advanced algorithms to analyze factors such as battery health, state of charge, and user preferences to improve the charging sequence. In some embodiments, the processor may continuously monitor the charging process and / or adjust the power distribution in real-time. For example, these adjustments may increase efficiency. The system may also provide users with the option to override the default priority settings through a mobile app or user interface, allowing for greater flexibility and control.

[0148] FIG. 13 is a flow chart of an exemplary use of the electric vehicle charging system, in accordance with some embodiment of the invention. Exemplary method 129 relates to charging a plurality of electric vehicles (EVs) using multiple EV charging connectors. In some embodiments, the method includes connecting multiple vehicles to multiple EV charging connectors concurrently (Connect 130). Optionally, a single power source may be connected to multiple connectors via a selector switch, which may be controlled by a remote operator and / or automatically by a processor. Additionally, or alternatively, sensors that detect the battery status of each vehicle, such as the capacity of the battery, the rate of charging, and / or the charge state of the battery. For example, these sensors may be coupled to the connectors, and the processor may communicate with the EVs through the connectors to receive real-time data.

[0149] Once the vehicles are connected, the method proceeds to selecting one of the vehicles for charging (Select 132). In some embodiments, a processor may be configured for scheduling the charging and controlling the selector switch. For example, the processor may schedule which vehicle receives power based on various parameters, such as the order of arrival, the priority assigned to the vehicle, the timedependent cost of power, the battery status of the vehicle, and / or a predetermined time of finishing. Optionally, the power source and the number of connectors may be adapted to the particular environment and / or purpose of the charging station. For instance, in a residential parking gara ge where cars remain parked for long periods, each power source may be associated with a larger number of connectors.

[0150] The selected vehicle is then charged (Charge 134). In some embodiments, while one car is charging, a second vehicle may remain connected to its reversible connector. Optionally, multiple vehicles may remain connected to the reversible connectors while each of the vehicles is charged one at a time. The charging process may be monitored and controlled via a user interface, which allows users to define preferences such as the balance between cost and priority, or the balance between cost and time of charging. Additionally, or alternatively, the system may dynamically adjust power distribution based on real-time data from each vehicle being charged.

[0151] When the charging of the selected vehicle is finished, either due to reaching a chosen amount of charge or due to a new higher priority vehicle being connected to one of the multiple EV charging connectors, the method includes terminating the charging of the current vehicle (Terminate 133). In some embodiments, the termination process may be automatic, triggered by the processor based on the detected battery status or other predefined criteria. For example, the processor may detect when the battery is fully charged or when a higher priority vehicle requires charging, and subsequently terminate the charging of the current vehicle.

[0152] After terminating the charging of the current vehicle, the method proceeds to selecting a new vehicle for charging (Select 132). In some embodiments, the selection process may again be based on various parameters such as priority, battery status, and / or time-dependent cost of power. The processor may schedule the next vehicle to receive power according to these criteria, facilitating an efficient process. Optionally, the system may store data related to the charging history of each vehicle for future reference and analysis, aiding in predicting power demand and improving the charging schedule.

[0153] Finally, the new selected vehicle is charged (Charge 134). In some embodiments, the system may include multiple power sources connected through multiple selector switches to a larger number of connectors, providing more flexibility to the system. For example, multiple cars may be charged simultaneously, and when there is higher demand at one charging stand, multiple power sources may be directed to charge multiple cars at that stand simultaneously. Optionally, the power distribution may be dynamically adjusted based on real-time data from the vehicles and sensors, facilitating efficient and balanced charging across all connected vehicles.

Each connector is configured to connect reversibly to a corresponding EV, such as EVI 142a, EV2 142b, and EV3 142c, respectively. The system includes a selector switch 138 connected between the power source 136 and the EV charging connectors, allowing the selective activation of one connector at a time for charging purposes.

[0155] Optionally, the selector switch 138 is configured to select one of the EV charging connectors (e.g., connectorl 140a, connector2 140b, connector3 140c) and charge the associated vehicle. For example, EVI 142a connected to connectorl 140a may be selected for charging. When time comes to stop the charging of EVI 142a (e.g., due to reaching a chosen amount and / or the arrival of a higher priority vehicle and / or other reasons) the system terminates charging EVI 142a and selects a new vehicle, such as EV2 142b or

[0156] EV3 142c, for charging.

[0157] Additionally, the system may include a processor configured to control the selector switch 138 automatically. In some embodiments, the processor may schedule charging based on various parameters, such as the order of arrival at the charging station, payment for higher priority, certain makes or models of vehicles, time available for charging, required charging level, speed of charging, available type of charger, amount of charging required, or a combination thereof. This facilitates efficient use of the power source 136 according to user-defined preferences and system requirements.

[0158] Alternatively or additionally, the system may incorporate a user interface that allows users to interact with the charging system via their personal computing devices, such as cell phones. For example, users may set priorities for charging, specify times for charging, and inform the system of the duration they plan to be parked. This communication may be facilitated through a communication module, enabling the exchange of sensor data between the system and each connected vehicle.

[0159] In some embodiments, while one vehicle is charging, other vehicles may remain connected to their respective connectors. For instance, while EVI 142a is being charged, EV2 142b connected to connector2 140b and EV3 142c connected to connector3 140c may remain connected but not actively charging. Optionally, the system allows for the removal of connected vehicles and the connection of new vehicles to any available connectors, facilitating continuous and flexible use of the charging infrastructure.

[0160] Furthermore, the system may be adaptable to various environments and purposes, such as residential buildings, office buildings, delivery truck parking lots, commercial parking areas, and urban bus depots. The power source 136 and the number of connectors (e.g., connectorl 140a, connector2 140b, connector3 140c) may be adjusted according to the expected duration of vehicle parking and the number of vehicles requiring charging. For example, in a residential parking garage, a single power source may be associated with 4 to 10 connectors, while in a commercial parking lot, each power source may be associated with 2 to 5 connectors. A stronger power source may be used for larger vehicles and / or when there is less charging time.

[0161] According to some embodiments, an existing charging stand and / or an existing power source may be retrofitted for multiple vehicle charging. Optionally, a single connector may be replaced by multiple connectors and / or a selector switch. The multiple connectors may be configured for charging one vehicle at a time. The system may facilitate automated switching of charging between vehicles when the vehicles are parked for a long time.

[0162] FIG. 15 is a block diagram of an exemplary electric vehicle charging system with multiple power sources, in accordance with some embodiment of the invention. In some embodiments, system 191 is configured for charging a plurality of electric vehicles (EVs) includes multiple power sources connected to multiple EV charging connectors, allowing concurrent charging of multiple vehicles. For example, power source 136 is connected to selector switch 138, which in turn is connected to connectorl 140a, connector2 140b, and connector3 140c. Additionally, power source 137 is connected to selector switch 139, which is connected to connector2 140b, connector3 140c, and connector4 140d. This configuration allows for flexible and efficient distribution of power to various EVs based on demand and priority.

[0163] The selector switches, such as selector switch 138 and selector switch 139, play a crucial role in managing the connection between power sources and EV charging connectors. Each selector switch is configured to select one of the charging connectors and / or vehicles at a time for each power source. For instance, selector switch 138 can selectively connect power source 136 to either connectorl 140a, connector2 140b, or connector3 140c, while selector switch 139 can selectively connect power source 137 to either connector2 140b, connector3 140c, or connector4 140d. This selective connection facilitates the charging of selected vehicles based on predefined criteria.

[0164] One or more of the charging connectors may be connected to multiple power sources, providing additional flexibility in charging multiple EVs simultaneously. For example, connector2 140b is connected to both selector switch 138 and selector switch 139, allowing it to receive power from either power source 136 or power source 137. This configuration can be particularly useful in scenarios where there is an urgent demand for charging at more than one specific connector, enabling the system to allocate power any pair of vehicles simultaneously. For example, each EV charging connector may be connected to only one power source. This configuration simplifies the system and facilitates each connector receiving power from a dedicated source, reducing the complexity of power management. For example, connectorl 140a is exclusively connected to selector switch 138, which is in turn connected to power source 136, facilitating a direct and uninterrupted power supply.

[0165] The system may include a processor 141 configured to control the selector switches automatically. The processor 141 can manage the selection of charging connectors and vehicles based on various parameters such as arrival time, user- defined preferences, and battery status. For example, the processor 141 may prioritize charging a vehicle that arrived earlier or a vehicle with a higher priority set by the user. The processor 141 can also adjust the charging schedule based on the state of charge of each connected vehicle, facilitating efficient use of available power.

[0166] In some embodiments, the system may include a user interface that allows users to interact with the charging system. For example, users can use their computing devices, such as cell phones, to set charging priorities, define charging times, and provide information on how long their vehicle will be parked. This user interface can facilitate better management of charging schedules and facilitates users' preferences being taken into account.

[0167] The system is designed to terminate charging of a vehicle when it reaches a chosen amount of charge or when a higher priority vehicle is connected to one of the EV charging connectors. For instance, if a vehicle connected to connectorl 140a reaches its desired charge level, the system will terminate its charging and may select a new vehicle connected to connector2 140b or connector3 140c for charging. This dynamic management of charging sessions facilitates efficient utilization of available power and charging connectors.

[0168] In some embodiments, the system may include sensors to detect the battery status of each connected vehicle. These sensors can provide real-time data on battery capacity, rate of charging, and charge state. For example, a sensor coupled to connector3 140c can monitor the battery status of the connected vehicle and communicate this information to the processor. This data can be used to make informed decisions on charging priorities and schedules.

[0169] The system may also include a communication module for exchangi ng sensor data with each connected vehicle. This module can facilitate two- way communication between the system and the EVs, allowing the vehicles to report their battery status and receive updates on their charging progress. For example, the communication module can be used to send notifications to users about the charging status of their vehicles, such as when charging is complete or if there are any issues.

[0170] In some embodiments, the system may be configured to distribute power differentially to each EV based on various parameters, including user-defined preferences, state of charge, and historical charging data. For example, the processor may allocate more power to a vehicle with a lower state of charge or a vehicle that needs to be charged quickly due to an upcoming trip. This differential power distribution facilitates the system meeting the specific needs of each user while improving overall efficiency.

[0171] Additionally, the system may include a network connection to external entities such as energy suppliers, financial institutions, or users' personal computing devices. This network connection can facilitate various functions, including payment processing, monitoring power demand, and accessing additional data to predict future power needs. For example, the system can communicate with an energy supplier to manage power supply based on real-time demand and cost, facilitating efficient and cost-effective charging for all connected EVs. According to some embodiments, an existing charging station may be retrofitted for multiple vehicle charging. Optionally, a single connector may be replaced by multiple connectors and / or a selector switch. The multiple connectors may be configured for charging one vehicle at a time. The system may facilitate automated switching of charging between vehicles when the vehicles are parked for a long time. A processor and / or sensors and / or a user interface may be added to control and / or adjust the charging between the vehicles.

[0172] FIG. 16 is a flow chart of an exemplary method of electric vehicles, in accordance with some embodiment of the invention. For example, in method 192, multiple vehicles are connected 130 to multiple charger ports of a power supply. Charging priority is set 146 by a user via a user interface and / or automatically, in accordance with an algorithm. A vehicle of said multiple vehicles is selected 148. The selected vehicle is charged 134. After a period of time, the system may check 152 whether charging has finished. If charging has finished (e.g., has arrived at a desire level of charge and / or time and / or some other reason), the system may terminate 133 charging of the vehicle and select 135 a new vehicle to charge. At any time, a vehicle may be moved 154. For example, a user may remove his vehicle from the charging user and / or a new user may move 154 a new vehicle to the charging station and / or connect a new vehicle to an EV charging cable. When the population of cars changes the system may reset 146 priorities and decide if to select 150 a new car for charging. For example, if a high priority new vehicle moves 154 in and connects, charging a currently vehicle may be terminated 133 and the new vehicle selected 150 and charged 134. If a currently charging vehicle is moved 154, charging may be terminated 133 and a new vehicle selected 150 and charged 134. Alternatively or additionally, moving a car may not change a selection 150 and / or charging 134 may continue. If charging 134 has not been finished 152, then the system may continue charging 134 the selected vehicle or the system may terminate 133 charging and select 150 a new vehicle to charge based on the priorities set 146. The completely or partially charged vehicle may be moved 154.

[0173] FIG. 17 is a block diagram of an exemplary electric vehicle charging system, in accordance with some embodiment of the invention. For example, system 178 is configured for charging a plurality of vehicles includes a power source 180, a plurality charging stands 182. Each charging stand may include a power cord may be configured to connect to a respective charging port of a vehicle of the plurality of vehicles, regardless of the location of the charging port on the vehicle. The system may include a connection subsystem 184 (e.g., access port and / or a permanent connection) configured to establish a between the charging port and the power source 180 for each charging stand of the plurality of charging stands concurrently. Optionally the connection between the power source 180 and the charging stand 182 is independent of the position of charging port on the vehicle this is connected to the charging stand. The system may include a processor 186. Processor 186 may be configured to determine a charging priority of the plurality of vehicles and to distribute power differentially to each charging stand 182 according to the priority of a vehicle connected to the charging stand 182.

[0174] FIG. 18 shows Table 1 which is an exemplary schedule of charging, in accordance with some embodiments of the invention. For example, one vehicle at a time may be charged (e.g., EVI, EV2 or EV3). Optionally, the system may facilitate automatic switching charging between vehicles. Optionally, charging may take different times for different vehicles (e.g., due to previous charge level and / or rate of charge of different batteries and / or type of vehicle and / or age of battery, etc.). Optionally, charging may be performed in stages (e.g., each vehicle is charged to 85% capacity by fast charging and may then receive a slower top off to 100%). Optionally, charging to 100% may be performed at off-peak times.
