Description

  The present invention relates to an automobile battery system and a charging technique thereof, and more particularly to an automobile battery system using a secondary battery and a charging apparatus and method therefor.

  Although electric vehicles have been put into practical use for a long time, there are many barriers to be solved technically, such as initial cost and mileage, and they have not been exploded. However, the recent increase in environmental awareness, including the reduction of carbon dioxide, has raised expectations for electric vehicles. Japanese companies in particular are resistant to environmental problems, and the automobile industry has led the world in the past with the introduction of many new technologies. According to the “Next-Generation Vehicle Strategy 2010” report compiled by the Ministry of Economy, Trade and Industry, the government's target value for externally charged electric vehicles, namely EV (pure electric vehicle) and PHEV (plug-in hybrid electric vehicle) Will account for 15-20% of new car sales as of 2020. The days when electric cars are usually seen in the city are not far away.

  One of the issues that have hindered the widespread use of electric vehicles is the length of time for charging lithium-ion batteries and other secondary batteries installed in automobiles. Currently, charging generally takes several hours, and the target is 20 to 30 minutes even if the companies are competing for development. Even if the number of charging stations increases, it seems that “charging congestion” cannot be avoided due to the long charging time.

  In order to solve such a problem, Patent Document 1 discloses a technique in which a charging facility is provided in a parking lot, and a charging terminal is extended from the bottom of an automobile so that charging is performed during parking. According to this technology, since the vehicle can be charged while parked without going to the charging stand, problems related to charging time can be reduced.

JP-A-6-121407

  The present inventor has recognized the following problems in realizing the technique of Patent Document 1. First, a special charging terminal is required at the bottom of the electric vehicle. This terminal needs to be housed in a position that does not hinder traveling during traveling. The bottom of the automobile is also a place where foreign matter hits, and it is necessary to consider the structure. Because of this technology, it is necessary to change the design of existing electric vehicles accordingly, and it is necessary to consider the realization cost.

  Next, with this technology, it is necessary to take into account the differences between electric vehicle models. The clearance between the bottom and the road differs depending on the model. Also, the location where the charging terminal can be placed differs depending on the chassis structure. Therefore, it is necessary to keep the charging terminal on the parking lot side wide, but even if you do so, if the parking position of the car shifts laterally, the terminals of the same polarity between the car and the parking lot Contact becomes difficult.

  This invention is made | formed in view of such a subject, The objective is to implement | achieve charge during parking more simply and reliably.

  The vehicle battery system of the present invention includes a secondary battery, a charging port, and an electric path for transmitting electric power applied to the charging port to the secondary battery, and the charging port is standardized for a plurality of types of vehicles. With respect to the positions of the members, the plurality of types of automobiles are provided at a common position. The charging port may be of a type that makes contact with the power transmission terminal on the charging device side, or may be of a non-contact type using electromagnetic induction or the like, and may have any shape. The charging port may be a predetermined component of a standardized member.

  The charging device of the present invention includes a sensor that detects a charging port provided in an automobile, a power transmission terminal that is electrically connected to the detected charging port, and a power source that supplies power to the power transmission terminal.

The electrical connection between the charging port and the power transmission terminal may be contact or non-contact. The power transmission terminal may have any shape such as a plug shape or a planar shape.

  The charging method of the present invention includes a step of recording conditions for permitting or prohibiting external charging of an automobile having a secondary battery, and an automobile having a secondary battery at a position where the charging device can be used. When the vehicle enters the vehicle, the condition is detected for the vehicle, and it is determined whether or not the current charging for the vehicle is permitted, and if it is determined that the current charging is permitted, Performing charging by the charging device.

  According to another charging method of the present invention, when a vehicle having a secondary battery enters a position where the charging device can be used, a device that records the intention of the driver or the driver in advance as to whether or not charging is permitted for the vehicle. And when charging is permitted as a result of the inquiry, charging by the charging device for the vehicle is included.

According to another charging method of the present invention, when a vehicle having a secondary battery is charged from the outside, the step of determining whether the charging is approved by the driver and the permission is obtained. If not, invalidate the charge that occurs for the charge.

  The vehicle battery system of the embodiment has a secondary battery incorporated in an electric vehicle (EV) and a port for charging from the outside (hereinafter referred to as “charging port”), and these are connected by an electric path. . The secondary battery can be charged by connecting the charging device to the charging port and applying power. The characteristic of an Example is that the charge port is provided in the common position about the vehicle of several types of vehicles on the basis of the position of the member normalized about the vehicle of multiple types of vehicles.

  Here, a license plate is adopted as a standardized member. The license plate is the official name of “automobile registration number mark” for automobiles (registered cars), and “vehicle number mark” for minicars and motorcycles. It is called a plate.

  The license plate is standardized in each country, and the shape, information to be written and its format are standardized. In Japan, ordinary passenger cars are commonly used as “medium plates” with a width of 33 cm and a height of 16.5 cm. In addition, a large truck having a total vehicle weight of 8 tons or more and a maximum loading capacity of 5 tons or more is provided with a “large plate” having a width of 44 cm and a length of 22 cm. The shape of the license plate is limited, and the size can be specified from the description of the license plate. Further, as indicated by reference numeral 10 in FIG. 1, the vehicle is located almost in the center of the front surface, so that it can be easily identified by image recognition.

[1] Battery System for Automobile FIG. 2 shows the appearance of the license plate 10. The number plate 10 is attached with two bolts, and a metal sealing cover 12 is covered on one side. The other bolt 14 is exposed as it is. These positions are determined in the license plate 10. These are used in the embodiment.

  The battery system 100 of FIG. 3 is inside the electric vehicle. The positive electrode of the secondary battery 20 and the sealing cover 12 of the license plate 10 are connected by an electric path 22. Similarly, the negative electrode of the secondary battery 20 is grounded together with the bolt 14. For this reason, it is assumed that the sealing cover 12 and the bolt 14 insulate the attachment portion so as not to conduct with the vehicle body and other members. (However, for the bolt 14, if the vehicle body also serves as the signal ground as it is, it is not necessary to insulate, but rather it can be grounded as it is at the bolt tightening portion, which is convenient.)

  A switch 24 such as a relay for interrupting the electric path 22 is inserted in the electric path 22. The switch 24 is turned on and off by the charge control unit 30. The charging control unit 30 controls on / off of the switch 24 using information from the sensors. For example, when it is known from the information of the speed sensor that the electric vehicle is running or when it is known from the information of the seat sensor that there is an occupant, charging from the outside is inappropriate and the switch 24 is turned off.

  In this embodiment, the charging control unit 30 normally turns off the switch 24, further considers the weighting condition obtained from the driving support system 26, and turns on the switch 24 only under limited conditions. The driving support system 26 has a car navigation system as a core, but is a comprehensive system that provides various services to passengers. The occupant makes various settings using the touch panel 32 and obtains various information. In the present embodiment, as will be described later, the touch panel 32 inputs a condition for permitting the external charging by the driver and a condition for stopping the started charging. The touch panel 32 also functions as a notification unit that displays information such as a charge system for charging by the charging device as described later. The charging controller 30 may turn on the switch 24 only when the driver explicitly inputs “charge permission” via the touch panel 32.

  The charging permission / stop condition may be input to the driver every time the electric vehicle receives an inquiry from the charging device, but can be input to the driver from the touch panel 32 in advance (the former is the sequential registration, the latter Called pre-registration) The registration contents of the sequential registration may be recorded in a memory inside the driving support system 26, but in the case of pre-registration, the contents may be inside the driving support system 26 or via a communication device 28 of a service center described later. You may register with the server. When the server is used, it is possible to determine whether or not charging is possible even when the driving support system 26 is turned off while the automobile is stopped. As the communication device 28, road-to-vehicle communication and other arbitrary communication functions can be used.

  In any case, according to the present embodiment, the sealing cover 12 and the bolt 14 which are present at a fixed position in the license plate 10 which are present regardless of the vehicle type and are standardized are charging ports. The position can be easily identified from the charging device by image recognition, and automatic connection of the power transmission terminals is facilitated.

  However, this embodiment is also useful when automatic charging by a charging device is not used. This is because the sealing cover 12 and the bolt 14 existing in all automobiles are used, so that it is not necessary to newly provide a charging port, and an ideal solution is provided for all of the cost, design and aesthetic aspects. .

[2] Charging device
FIG. 4 is a perspective view of one parking slot 210. The car stops by hitting the front wheel against the car stop 212. The charging device 200 is installed in a state where the back surface is attached to the front wall surface of the parking slot 210. The charging device 200 includes a camera 40 that detects a license plate 10 of a stopped automobile, a sealing cover 12 provided on the license plate 10, and a first power transmission terminal 50 and a second power transmission terminal 52 that are in contact with the bolts 14, respectively. Base portions of the first power transmission terminal 50 and the second power transmission terminal 52 are provided in the lifting box 214. The lifting box 214 can be moved up and down with respect to the charging device 200. The first power transmission terminal 50 and the second power transmission terminal 52 can be moved left and right in the lifting box 214 and can be moved forward, that is, to the number plate 10 side. The charging device 200 may be installed in front of all the parking slots 210, or may be installed in front of a specific parking slot 210. In terms of business, the parking slot 210 in which the charging device 200 is installed has a room to turn on a somewhat special charge for the parking charge, apart from the charge for charging described later.

  The lifting box 214, the first power transmission terminal 50, and the second power transmission terminal 52 are driven by actuators inside the charging device 200. The actuator is controlled based on the image from the camera 40, and the first power transmission terminal 50 and the second power transmission terminal 52 are controlled so that the contact becomes a predetermined pressure when contacting the sealing cover 12 and the bolt 14, respectively. The

  FIG. 5 shows the internal configuration of the charging device 200. The video of the camera 40 is sent to the image recognition unit 42. The image recognition unit 42 searches the license plate 10 by a known method, and detects this when the automobile stops in the parking slot 210. The main control unit 44 directly communicates with the communication device 28 of the automobile via the communication device 56 or communicates with a server of a service center described later to determine whether charging is permitted. When making an inquiry to the server, the main control unit 44 transmits the number recognized by the image recognition unit 42 to the server from the stopped automobile. Based on the number, the server specifies the contents of the above-mentioned pre-registration, returns this to the main control unit 44, and the main control unit 44 determines whether or not charging is permitted. The main control unit 44 may first try short-range communication with the automobile communication device 28 and access the server when there is no predetermined waiting time response.

Pre-registration takes the form of conditions for permitting and stopping charging. The permission condition is, for example, as follows in relation to the information related to charging.
・ Allow at any time.
・ Allows for charging places A, B, and C.
・ Allows if the unit price of electricity related to charging is D or less.

When information on the battery or the electric vehicle itself is necessary as described below, the main control unit 44 may acquire the information directly from the communication device 28 of the electric vehicle or via a server.
・ Allow if battery level is E or less.
・ Allowed if the mileage is F or less.

On the other hand, the conditions for stopping charging are as follows in relation to information on charging or information on the battery or the electric vehicle itself.
-The elapsed time from the start of charging is G.
・ The charge for charging became H.
・ The remaining battery level has recovered to I.
・ The driving distance has recovered to J.

  When the main controller 44 determines that charging is permitted at this time as a result of referring to the condition for permitting charging, the actuator group 46 is driven, and the first power transmission terminal 50 and the second power transmission terminal 52 are connected to the sealing cover 12. The bolts 14 are brought into contact with the bolts 14 at a predetermined pressure. Detailed positions of the sealing cover 12 and the bolt 14 are specified by the camera 40 and the image recognition unit 42. After the contact is completed, the main control unit 44 permits the supply of power from the power source 54 to the first power transmission terminal 50 and the second power transmission terminal 52. Thereby, charging of the secondary battery 20 of the electric vehicle is started. Conversely, when the charging stop condition is satisfied, the main control unit 44 stops the power supply from the power source 54 and returns the first power transmission terminal 50 and the second power transmission terminal 52 to the original storage positions. The billing information generation unit 48 generates billing information based on the charged amount of electricity, and transmits this to the main control unit 44. After this, there are the following two methods for actual billing.

  1. The main control unit 44 notifies charging information related to charging to a parking fee settlement system (not shown). When this electric vehicle leaves, the payment system charges the parking fee with the charge.

  2. The main control unit 44 notifies the billing information to the service center server via the communication device 56. After the server checks the validity of the billing information, it settles by a known method based on the driver's credit card information and the like.

  With the above configuration, it is possible to smoothly charge the vehicle while the driver is not in use. In this case, whether or not charging is permitted is determined based on the contents of the pre-registration, but of course, it can also be determined from the contents of the sequential registration. In that case, the driving support system 26 of the vehicle transmits the driver's intention via the communication device 28 in response to the charge permission / inquiry from the charging device 200. Therefore, first, the driving support system 26 uses the touch panel 32 to inquire whether or not to charge the driver. At that time, in order to help the driver's judgment, information related to charging, such as a unit price of electricity related to charging, is notified. The driver may make a determination based on the information and notify the charging apparatus 200 of his / her intention from the touch panel 32 via the communication device 28.

[3] Service Center FIG. 6 shows the configuration of the service center 300. The service center 300 includes a communication device 78 that communicates with the communication device 28 of the automobile and the communication device 56 of the charging apparatus 200, and a server 70 that manages pre-registration information and billing. The server 70 associates and stores the number of the license plate 10 and the contents of the pre-registration, the charging check unit 74 for checking the validity of the charging information sent from the charging device 200, and the charging information is valid. When approved, it includes a charging execution unit 76 that performs a charging proxy process for the operator of charging device 200.

  When charging is performed while there is no driver in the parking lot, it is important to check the validity of the billing. Whether it is pre-registration or sequential registration, it is information relating to the driver's intention, so this information is protected by known information security techniques so as not to be tampered with. As the first inspection item, the charging inspection unit 74 determines whether or not this charging satisfies the condition for permitting charging from the contents of pre-registration or sequential registration, in other words, whether or not this charging is permitted by the driver. Check if.

  Subsequently, the charge check unit 74 checks the validity of the charge amount. Therefore, the amount of electricity charged by the charging device 200 is also protected by the same information security technology as described above. The charging inspection unit 74 acquires the remaining amount of the secondary battery 20 when charging is started and when charging is stopped via the communication device 28 of the electric vehicle, and confirms consistency with the charged amount of electricity. By checking the validity of the amount. What is necessary is just to acquire the residual amount of the secondary battery 20 from control ECU of the secondary battery 20 which is not shown in an electric vehicle.

  The charging execution unit 76 executes the charging process when the charging check unit 74 confirms the validity of the charging. Conversely, when the validity cannot be confirmed, the charging execution unit 76 invalidates the charging information and does not execute charging for charging. As a result, it is possible to prevent an unforeseen situation such that the driver is charged and charged without the knowledge of the driver, or charging is permitted, but an unreasonable fee is charged.

[4] Overall Operation The operation of the embodiment having the above configuration will be described below. 7 to 9 show a processing flow for charging the automobile when it is parked. Here, pre-registration is used. As shown in FIG. 7, first, as a preparation, the driver registers a charging condition in the local memory of the driving support system 26 or in the condition recording unit 72 of the server 70 via the communication device 28 (S10). The charging condition is a general term for a condition for permitting charging and a condition for stopping charging.

  As shown in FIG. 8, it is assumed that the car enters the parking lot (S20) and parks in the parking slot 210 of FIG. Parking is detected by the cooperation of the camera 40 and the image recognition unit 42, and the main control unit 44 accesses the condition recording unit 72 of the server 70 via the communication device 56 based on the information of the license plate 10. The main control unit 44 determines whether or not the charging permission condition recorded in the condition recording unit 72 is satisfied at the present time (S30). When it is determined that the condition is not satisfied (S30N), the main control unit 44 does nothing and ends the present flow. Conversely, when it is determined that the condition is satisfied (S30Y), the main control unit 44 controls the actuator group 46 so that the first power transmission terminal 50 and the second power transmission terminal 52 are sealed with the sealing cover 12 and the bolt 14 of the license plate 10, respectively. And the power supply 54 is turned on to start charging (S40).

  After starting charging, the main control unit 44 repeatedly determines whether or not the charging stop condition is satisfied (S50N). When the charging stop condition is satisfied (S50Y), charging is stopped (S60), charging information is generated by the charging information generating unit 48 (S70), and this is sent to the server 70. The above is the processing by the charging device 200.

  FIG. 9 is a processing flow by the server 70. When the server 70 receives the billing information (S100), the legitimacy is checked by the billing inspection unit 74 (S110). When the validity is confirmed (S110Y), charging by the charging execution unit 76 is executed (S120), and the process ends. If the validity is not confirmed (S110N), the billing information is invalidated by the billing inspecting unit 74 (S130), and the processing ends without performing billing.

  As described above, according to the present embodiment, simple and reliable charging can be performed regardless of the vehicle type while the electric vehicle is parked. For this reason, there is no need to change the car design. Furthermore, conditions for permitting charging (in other words, prohibition) can be set in detail, and charging in accordance with the driver's intention can be secured. In addition, it is possible to more reliably respect the driver's intention by setting a stop condition for charging that has been started once. Moreover, it is possible to check the legitimacy of charging under conditions where it is difficult for the driver's eyes to park, and unexpected charging and charging can be prevented. The present embodiment solves various problems in anticipation of the popularization of electric vehicles.

[5] Modification technology The charging port may be other than the sealing cover 12 and the bolt 14. If the position is in a predetermined positional relationship with a standardized member such as the license plate 10, the position can be easily specified by image recognition or other methods. For example, a standard for providing a charging port at a predetermined location outside the license plate 10 for a new electric vehicle may be created. Even in this case, the charging port can be easily found using the license plate 10 as a clue.

2. The sealing cover 12 and the bolt 14 are considered to be those of the license plate 10 at the front of the automobile, but of course, they may be those of the rear license plate 10. The front plate 10 and the rear license plate 10 may be used together. In that case, what is necessary is just to electrically connect the sealing cover 12 and the bolts 14 of these two license plates 10 on the side farther from the secondary battery 20 than the switch 24. This mode is useful because the car can be parked forward or backward.

3. Although the charging device 200 of the embodiment is a stationary type, it may be a self-propelled robot type. In that case, the charging device 200 is self-propelled in the space on the wide side of the parking lot, that is, the space where the electric vehicle moves until it enters the parking slot, and the license plate of the electric vehicle is detected by the cooperation of the camera 40 and the image recognition unit 42. And you can charge the electric car.

  However, this robot does not need to be designed to be so sophisticated that it looks for a license plate anywhere. Since the electric vehicle is parked in the parking slot, in many cases, it is sufficient to configure the robot to reciprocate at a certain distance from the parking slot. For example, in the case of the charging device 200 of FIG. 4, it may be configured such that it can be driven laterally behind the parking lot slot (that is, in the direction of moving behind the plurality of parking slots). Thereby, charging is possible in a plurality of parking slots.

  The charging device 200 is preferably a fixed type or a mobile type, and is preferably placed in a dead space behind the parking space from the viewpoint of electric shock prevention and contact prevention. It is desirable to define an entry prohibition area and install the charging device 200 fixedly or movably in the area.

4). The main control unit 44 directly inquires the vehicle whether or not charging is possible or inquires the server 70. However, the main control unit 44 itself has information that is locally used as a determination material, and may make the determination itself within a possible range. For example, when the description contents of the license plate 10 are different between a gasoline vehicle and an electric vehicle, the main control unit 44 has the information. When the description content of the license plate 10 acquired by the camera 40 and the image recognition unit 42 indicates that the vehicle is a gasoline vehicle, the main control unit 44 does not bother to make an inquiry and determines that charging is prohibited. Can do.

5. When the self-propelled robot type charging device 200 is used as described in 3 above, a large number of electric vehicles can be visited and charged in a large parking lot such as a shopping center. If this charging is performed by a service on the side of a parking lot such as a shopping center and no charge is made, it will be a single customer attraction model. However, as described above, charging takes a considerable amount of time. For example, if 100 electric vehicles are parked in a parking lot, it is difficult to complete charging of all electric vehicles during the driver's shopping time.

  When such a problem is foreseen, a method of limiting the vehicles to be charged with identification information of an electric vehicle, specifically, a license plate, can be considered. For example, if “the day with an even date is charged to a car with the last digit of the number being charged, and the day with an odd number is charged to an odd number of cars as well”, the number of target cars is almost half a day. If "Today's car has the last digit of the number 0", the target cars for that day will be almost 1/10. Conversely, it can be said that it is a model that attracts users of electric vehicles that meet the conditions on a specific day. In addition, the condition as to which electric vehicle is to be charged on any day or timing is hereinafter referred to as “target selection condition”.

  The charging device according to the modified technique is electrically connected to a first sensor that detects a charging port provided in an automobile, a second sensor that detects identification information of the automobile, and a charging port detected by the first sensor. Main control for determining whether or not to charge the vehicle based on the identification information detected by the second sensor, and the power supply 54 for supplying power to the power transmission terminals 50 and 52 Part 44.

  The first and second sensors may be used in common and may detect the charging port and identification information, that is, the license plate by an image recognition method, and the set of the camera 40 and the image recognition unit 42 in FIG. The image recognition unit 42 can recognize the number on the license plate as described above. Therefore, the main control unit 44 can determine whether or not the electric vehicle photographed by the camera 40 satisfies the target selection condition. The object selection condition may be stored in advance in a memory (not shown) in the main control unit 44 by the parking lot operator, or from the server 70 to the memory via the communication devices 78 and 56, for example, every day. It may be set. In any case, the charging device 200 can charge the electric vehicle determined to satisfy the target selection condition according to the procedure described above.

  Although the first and second sensors are single here, they may be different and may not be the image recognition type. For example, the electric vehicle side charging port may be specially processed, and the first sensor may detect the processed charging port. A special paint may be applied to the charging port, a special magnetic process may be applied, or a communication device that emits weak radio waves may be incorporated. In any case, the first sensor can detect the charging port by a corresponding method.

  As described above, according to this modified technique, although the charging time for an electric vehicle is generally long, a parking lot providing side or a customer drawing side can create a new customer drawing model called a charging service for an electric vehicle and operate it with a sense of fairness. it can.
