[0017] With this type of vehicle-server system, vehicle users can obtain information on the health of the charger determined by the server, thus improving convenience for vehicle users when charging.

[0018] The vehicle charging systems disclosed herein will be described below with reference to the drawings as appropriate. Figure 1 is a diagram showing an example of a charging system.

[0019] The charging system 100 shown in FIG. 1 includes a vehicle 2 of a certain user, a vehicle 4 of another user, and a server 80. Vehicles 10 and 11 are both, for example, electric vehicles equipped with a battery 12. Further, the charging system 100 can include a number of vehicles other than vehicles 2 and 4. The charging system 100 is related to the use of a charger 70 installed outside vehicles 10 and 11, but is related to the use of a number of chargers other than the charger 70.

[0020] Vehicles 10 and 11 are both configured to be able to perform "external charging" to charge the battery 12 with the power supplied from the charger 70. Vehicle 10 has at least the same configuration regarding external charging. In the following description, when describing the same configuration of vehicles 10 and 11, they are collectively described as vehicle 10 and the like. Vehicle 10 and the like can be connected to the charger 70 by wire via a charging cable 72. Note that vehicle 10 and the like only need to be configured to enable external charging, and may be a plug-in hybrid vehicle, a fuel cell vehicle, or the like.

[0021] Vehicle 10 and the like include a battery 12, a power control unit (PCU) 14, a motor generator (MG) 16, and an electronic control unit (ECU) 20.

[0022] (Battery) The battery 12 is a rechargeable power storage device and is configured to include a secondary battery such as a lithium-ion secondary battery or a nickel-metal hydride battery. The battery 12 supplies power for generating the driving force for the vehicle 10 to the PCU 14. Also, the battery 12 is charged by the power generated by the regenerative braking of the MG 16 or by the supplied power from the charger 70. Note that instead of the battery 12, a capacitor such as an electric double layer capacitor may be employed.

[0023] The battery 12 is equipped with a voltage sensor, a current sensor, and a temperature sensor (not shown), and outputs the detection results from these sensors to the ECU 20. The ECU 20 calculates the State of Charge (SOC) of the battery 12 based on these detection results.

[0024] (PCU) The PCU14 is a power conversion device connected to the battery 12 that performs power conversion between the battery 12 and the MG16 according to commands from the ECU20. The PCU14 includes an inverter that receives power from the battery 12 to drive the MG16, and a converter (neither of which is shown) that adjusts the level of the DC voltage supplied to the inverter.

[0025] (MG) The MG16 is an AC motor, specifically a permanent magnet synchronous motor equipped with a rotor (not shown) in which permanent magnets are embedded. The MG16 is driven by an inverter included in the PCU14, which rotates the drive shaft (not shown). The MG16 also generates electricity when the vehicle is braking, receiving the rotational force from the drive wheels, and charges the battery 12 through the PCU14.

[0026] (ECU) The ECU 20 consists of a CPU, memory, and input / output ports for inputting and outputting various signals. The ECU 20 controls various devices within the vehicle 10 (PCU 14, various relays, DC / DC converter 32, etc.) so that the vehicle 10 is in a desired state. The ECU 20 also transmits various information (such as the location information of the vehicle 10) to the server 80 and receives information from the server 80 via the communication device 50 described later. The ECU 20 may be a higher-level control unit itself, or it may be under the control of a higher-level control unit.

[0027] When a vehicle 10 or the like is connected to the charger 70, the ECU 20 acquires and stores power supply information related to the power supply status, such as waveform data including voltage waveform, peak value, amplitude, and frequency of the power supplied from the charger 70 to the power receiving unit 30, as well as data related to current. It also transmits this information to the server 80 via the communication device 50 to request the server 80 to execute a process to determine the health of the charger 70.

[0028] Furthermore, the ECU 20 performs a process to provide health information of the charger 70 to the user, such as the vehicle 10, prior to the battery 12's SOC decreasing and requiring charging. Specifically, the ECU 20 obtains health information of several chargers, including the charger 70, that are within a drivable distance range from the vehicle 10's current location, from the server 80, and provides the user with this health information of the chargers.

[0029] (Power receiving section) Vehicle 10, etc., is configured as a vehicle equipped with a battery 12 that can be externally charged, and includes a power receiving unit 30. The power receiving unit 30 includes a DC / DC converter 32, as well as a voltage sensor 36, a current sensor 38, power lines PL and GL, and an inlet 40.

[0030] When charging the battery 12, the connector 74 of the charging cable 72 is connected to the inlet 40. Power supplied from the charger 70 is supplied to the vehicle 10, etc., through the power lines in the charging cable 72. The power is further transmitted to the DC / DC converter 32 of the power receiving unit 30 through the power lines PL and GL. The DC / DC converter 32 converts the power supplied from the charger 70 into power for charging the battery 12, according to the command from the ECU 20. The DC / DC converter 32 may also be configured to convert the power from the battery 12 into power for output to the outside of the vehicle.

[0031] The connection between the DC / DC converter 32 and the battery 12 is closed by a command from the ECU 20, which closes the charging relay and other components, enabling power transmission between the inlet 40 and the battery 12.

[0032] The voltage sensor 36 is electrically connected between power line PL and power line GL. When the charger 70 is connected to the vehicle 10, etc., the voltage sensor 36 detects the voltage, waveform, amplitude, frequency, etc. of the power supplied from the charger 70 to the DC / DC converter 32, and outputs the detection results to the ECU 20.

[0033] The current sensor 38 is electrically connected to the power line PL. When the charger 70 is connected to the vehicle 10, etc., the current sensor 38 detects the current flowing from the charger 70 to the DC / DC converter 32 and outputs the detection result to the ECU 20.

[0034] (Communication equipment) Vehicle 10, etc., is further equipped with a communication device 50 via a dedicated communication line, configured to communicate with a server 80 outside the vehicle for sending and receiving information. The communication device 50 and the ECU 20 are connected to each other by a wired in-vehicle network or the like, and are configured to communicate with each other. The communication device 50 may be capable of sending and receiving information with the user's mobile terminal in vehicle 10, etc., or a separate communication device for such mobile terminal may be provided. In addition, vehicle 10, etc., may be equipped with a separate communication device for sending and receiving information via an internet line. Such various communication devices can be appropriately designed and acquired by a person skilled in the art according to the purpose.

[0035] Vehicle 10 is further equipped with a GPS receiver that determines its current location based on radio waves from artificial satellites. The GPS receiver acquires location information (GPS information) of the vehicle 10's current location and transmits the acquired location information to the server 80. Using the location information, the navigation system display in vehicle 10 can display various information such as the vehicle's current location, driving route, target location, and location information of numerous chargers, including charger 70, according to the vehicle's driving status and the battery 12's SOC.

[0036] (charger) The charger 70 is, for example, a fast charger installed at a public charging station (also referred to as a charging spot or charging station). The charger 70 is configured to convert AC power supplied from a commercial power source (for example, a 3-phase 200V power supply) into DC power and supply that DC power to the vehicle 10. The charger 70 is not particularly limited and may be a wireless charger, encompassing various known forms of chargers. Depending on the form of the charger 70, the form of the power receiving unit 30 of the vehicle 10 may be changed as appropriate.

[0037] The charger 70 is equipped with a charging cable 72, which is connected to an inlet 40 of the vehicle 10, etc., via a connector 74. The charging cable 72 is equipped with power lines 76 and signal lines, etc.

[0038] (server) Server 80 functions as a computer that receives requests from other computers, such as the ECU 20, installed in vehicle 10, and returns information and processing results. Server 80 is configured to communicate with communication devices 50 of multiple vehicles, including vehicle 10. Server 80 manages power supply information of multiple chargers, including charger 70 (hereinafter simply referred to as charger 70, etc.), received from vehicle 10, etc. Furthermore, server 80 manages charger health information as a result of judgment regarding the health of charger 70, etc., based on the power supply information. Server 80 exchanges necessary information regarding the health of charger 70, etc., with vehicle 10, etc.

[0039] The server 80 obtains power supply information from the ECU 20, such as the voltage waveform of the power supplied from the charger 70, and current, and executes a process for determining and managing the health of the charger 70, etc. The server 80 also executes a process to provide health information of the charger 70, etc. to the ECU 20 of the vehicle 10, etc., in response to a request from the ECU 20 of the vehicle 10, etc. The following description will explain the detailed steps performed by the server 80.

[0040] Next, the process by which the server 80 of the charging system 100 determines the health of the charger 70 and manages the health information of the charger 70 will be explained with reference to Figures 2A and 2B. These processes are executed when the vehicle 10 connects to the charger 70 to charge the battery 12 from the charger 70, the power supply information of the charger 70 detected by the power receiving unit 30 is transmitted to the server 80 via the communication device 50, and the server 80 receives the power supply information.

[0041] As shown in Figure 2A, the server 80 monitors the reception of power supply information from the vehicle 10 to the charger. When the server 80 acquires power supply information from the charger 70 (step S10), the server 80 determines whether the acquired power supply information includes any malfunction cases caused by the charger that the server 80 has previously stored (step S20). The power supply information from the vehicle 10 includes the location information of the charger 70 and the identification information of the vehicle 10.

[0042] If the power supply information does not include any malfunction cases caused by the charger, the server 80 determines that the charger 70 is functioning correctly and is healthy. The server 80 stores the health information of the charger 70, along with its location information, in its memory (step S60), and then transmits the health information indicating that the charger 70 is functioning correctly to the vehicle 10 (step S70), before ending the process.

[0043] If the power supply information includes a malfunction case caused by the charger, the server 80 analyzes the waveform data contained in the power supply information (step S30) and determines whether the amplitude of frequencies other than the commercial frequency is below a threshold (step S40). If the amplitude of frequencies other than the commercial frequency exceeds the threshold, the server 80 determines that the charger 70 is not healthy due to a malfunction caused by the charger, stores the health information of the charger 70 along with the location information of the charger 70 in the server 80's memory (step S80), and terminates this process.

[0044] Furthermore, if the amplitude of frequencies other than the commercial frequency is below a threshold, the server 80 further determines whether the voltage peak value is below a certain level (step S50). If it exceeds the voltage peak value, the server 80 determines that the charger 70 is not healthy due to a malfunction caused by the charger, stores the health information of the charger 70 along with the location information of the charger 70 in the server 80's memory (step S80), and terminates this process.

[0045] When the voltage peak value is below the threshold, the server 80 determines that the charger 70 is healthy and free from any malfunctions caused by the charger, stores the location information of the charger 70 along with the health information of the charger 70 in the server 80's memory (step S60), transmits the health information indicating that the charger 70 is healthy to the vehicle 10 (step S70), and terminates this process.

[0046] Furthermore, when the server 80 performs the process shown in Figure 2B and stores health information indicating that the charger 70 is unhealthy, it further determines the health level of the charger 70.

[0047] As shown in Figure 2B, the server 80 monitors for the occurrence of health information indicating that the charger is unhealthy (step S110). If no health information indicating that the charger is unhealthy has been generated, the server 80 terminates this process and continues to monitor for the occurrence of health information.

[0048] When health information is generated indicating that the charger 70 is not in good condition, the server 80, based on the location information of the charger 70 included in the health information of the charger 70, refers to the past history of the health information of the charger 70 and determines whether the number of times it has been determined to be unhealthy is less than or equal to a specified number (step S120). If the number of determinations exceeds the specified number, the server 80 determines that the health of the charger 70 is at a level of "-2", which is such that it is recommended to avoid using the charger (step S150), updates the health information of the charger 70 with usage information including avoiding the use of the charger 70 (step S160), transmits this health information with the usage information to the vehicle 10 (step S170), and terminates this process.

[0049] If the number of checks is less than or equal to the specified number, the server 80 further determines whether the charger 70 falls under the category of vehicles that are subject to charging prohibition and have been notified to the server 80 by the manufacturer of the vehicle 10, etc., which is pre-stored in the server 80's memory (step S130). If the charger 70 falls under the category of vehicles that are subject to charging prohibition, the server 80 determines that the health of the charger 70 is "-2" (step S150), updates the health information of the charger 70 with usage information including avoiding the use of the charger 70 (step S160), transmits this health information to the user of the vehicle 10 (step S170), and terminates this process.

[0050] If the charger 70 is not subject to a charging ban, the server 80 determines that the health of the charger 70 is at a level of "-1", which means that the health of the charger 70 has not deteriorated to the point where it is recommended to avoid using the charger, but it has deteriorated to the point where it is recommended to alert the user of the vehicle 10 about the health of the charger 70 (step S140). The server 80 then updates the health information of the charger 70 with usage information, including a warning about using the charger 70 (step S160), transmits this health information to the user of the vehicle 10 (step S170), and terminates this process.

[0051] Next, a process in which vehicle 11, which is another vehicle in the charging system 100, utilizes health information of the charger 70 will be explained with reference to Figure 3. This process is performed when vehicle 11 is driving close to the charger 70 as a candidate charger for charging the battery 12.

[0052] As shown in Figure 3, the ECU 20 of the vehicle 11 requests the server 80 to transmit health information of the charger 70 via the communication device 50 (step S210). This transmission request includes the past history and health level of the charger 70.

[0053] The ECU 20 determines whether the received health information includes health information indicating that the charger 70 is not healthy (step S220). If such health information is not included, the ECU 20 displays on the vehicle 11's navigation system or other display that the charger 70 is healthy (step S230) and terminates this process.

[0054] If the received information includes health information indicating that the charger 70 is not healthy, the ECU 20 further refers to the health level of the charger 70 and determines whether the level is "-1" (step S240). If the level is "-1", the ECU 20 displays on a display such as the navigation system of the vehicle 11 that the use of the charger 70 is at a health level that warrants a warning (step S250), and terminates this process.

[0055] If the level is not "-1", the ECU 20 determines that the level is "-2", displays on the vehicle's navigation system or other display that the charger 70 is in good condition and its usage avoidance level is safe (step S260), and terminates this process.

[0056] As explained above, when the server 80 obtains power supply information from the vehicle 10 to the charger 70, it determines the health of the charger 70 and generates and manages health information for the charger 70. Furthermore, when health information is generated indicating a malfunction attributable to the charger 70, the server 80 checks the health of the charger 70 by referring to the history of the charger 70's past health status, determining the number of times its health status has been denied, and also determining whether it is a charger that is prohibited from charging as notified by the vehicle 10 manufacturer, thereby determining the health level of the charger 70 and updating the health information for the charger 70.

[0057] Furthermore, when charging from the charger 70 begins but before the charging operation starts, the vehicle 10 transmits power supply information from the charger 70 to the server 80. This provides the server 80 with the latest power supply information from the charger 70. The vehicle 10 can also receive health information for the charger 70 from the server 80. The user of the vehicle 10 can use the health information for the charger 70 to check the health of the charger 70, thereby avoiding or suppressing inconveniences such as damage to the vehicle 10's power receiving unit 30, long charging times, or inability to charge, and enabling safe and reliable charging of the battery 12.

[0058] Furthermore, when another vehicle, vehicle 11, plans to use charger 70 as a candidate charger when its SOC (State of Charge) decreases, it can send a request to server 80 to transmit health information for charger 70, and receive health information for charger 70 from server 80. Since the user of vehicle 11 can obtain health information for charger 70 well in advance of reaching charger 70, it is possible to avoid or suppress inconveniences such as damage to the power receiving unit 30 of vehicle 11, long charging times, or inability to charge, and to charge the battery 12 efficiently, safely, and reliably with a charger.

[0059] The collection and use of such health information will apply similarly to a large number of vehicles and chargers.

[0060] Based on the above, the charging system 100 disclosed herein allows users of vehicles such as 10 to obtain health information of chargers such as 70, thereby enabling safer and more reliable charging. As a result, the convenience of external charging for users is improved.

[0061] In the above description, the charging system 100 has been explained, but according to the above embodiment, the vehicles 10, 11 and the server 80 used in this charging system 100 can each contribute to the charging system 100 and can be said to have independent technical characteristics.

[0062] Furthermore, in the above explanation, the determination by the server 80 of whether the charger 70 has a malfunction caused by the charger (for example, steps S40 and S50) is just one example and is not limited to this. It can also be based on overvoltage from the voltage value, overcurrent from the current value, etc., included in the power supply information of the charger 70. For example, an overcurrent detected in the power receiving unit 30 may be an indicator of a malfunction in the power receiving unit 30. For example, the server 80 may execute the flow shown in Figure 4 as a modified example of Figure 2A.

[0063] As shown in Figure 4, the server 80 acquires power supply information from the charger 70 (step S310) and determines whether the power supply information includes malfunction cases caused by the power receiving unit 30 of the vehicle 10 (step S320). If the power supply information does not include malfunction cases caused by the power receiving unit 30, such as overcurrent, the server 80 terminates this process.

[0064] If the power supply information includes a malfunction case caused by the power receiving unit, such as an overcurrent, the server 80 determines that the power receiving unit 30 is malfunctioning and not in good condition, stores the health information of the vehicle's power receiving unit 30 along with the vehicle's identification information in the server 80's memory (step S330), transmits the health information indicating that the power receiving unit 30 is not in good condition to the vehicle 10 (step S340), and terminates this process.

[0065] In the above description, it is assumed that the server 80 feeds back health information of the charger 70 based on the power supply information of the charger 70 to the vehicle 10 that transmitted the power supply information of the charger 70, but this is not limited to the above. Also, in the above description, it is assumed that the server 80 transmits the health information to the vehicle 10, etc., but this is not limited to the above; the information is also provided to the user if it is transmitted to the user's mobile terminal, etc., of the vehicle 10, etc. Furthermore, the server 80 can also provide the charger health information to a wide range of general vehicle users as a charger health map or navigation system, etc.
