Description

  The present invention relates to a charging control device that controls an upper limit charging rate of a battery in an externally chargeable electric vehicle and a hybrid vehicle.

  2. Description of the Related Art Conventionally, a technology for charging a vehicle driving battery mounted on an electric vehicle such as an electric vehicle or a hybrid vehicle with a power source outside the vehicle is known. That is, the battery of an electric vehicle is charged using a household power source or a charging station. In such an electric vehicle, the battery can be easily charged by connecting the in-vehicle charger and the external power source using the charging cable.

  By the way, in normal external charging, the battery is charged until it is fully charged. On the other hand, in anticipation that regenerative power can be generated during braking, it has been proposed to stop external charging at a slightly lower charging rate than full charging (see Patent Document 1). In this case, it is conceivable that the user can arbitrarily set the charging rate upper limit value by using a meter system or a car navigation system installed in the vehicle interior. The information on the charging rate upper limit value set here can be referred to during external charging if it is transmitted to the battery control device via the in-vehicle communication network.

JP 2009-137416 A

  However, the convenience of the user cannot be improved simply by making it possible to set a plurality of types of charge rate upper limit values. For example, in a vehicle meter system and a car navigation system, there are various setting items such as setting of the type of information to be displayed on the display, setting of accuracy, setting of display contents, and setting of visibility. The contents included in are various. Therefore, it is difficult to find a target item in a short time. In particular, when a setting screen for setting the charging rate upper limit value is provided in a deep hierarchy in the menu, an operation for calling the setting screen is felt complicated for the user. On the other hand, considering the setting frequency of the charging rate upper limit value, it is difficult to provide the setting screen in a shallow hierarchy in the menu.

  The present case has been devised in view of the above-described problems, and an object thereof is to provide a highly convenient charge control device for setting a charge rate upper limit value when charging a battery by external charging. It should be noted that the present invention is not limited to this purpose, and is an operational effect that is derived from each configuration shown in “Mode for Carrying Out the Invention” to be described later. Can be positioned as a purpose.

(1) The charge control device disclosed here is a charge control device that controls an upper limit charge rate in external charging of a vehicle battery. The present charging control device detects a presence or absence of a prescribed operation in which a plurality of operations including an insertion operation for inserting a charging gun into a charging port of the vehicle and a signal transmission operation for transmitting a control signal to the vehicle are combined. Is provided. In the external charging, when the prescribed operation is detected by the detection unit, the battery is charged to the first charging rate, and when the prescribed operation is not detected, the battery is different from the first charging rate. The control part which charges to the 2nd charge rate of a value is provided. The prescribed operation includes an operation of pulling out the charging gun from the charging port, and an operation of subsequently inserting the charging gun into the charging port again.
In addition, it is preferable that the prescribed operation includes an insertion / extraction operation of the charging gun, and the insertion operation of the charging gun is performed a plurality of times. Thereby, it is possible to easily discriminate between the normal insertion operation and the specified operation in the external charging while eliminating the need for an input device other than the charging gun.

(2) It is preferable that the prescribed operation includes a first operation and a second operation. In this case, it is preferable that the detection unit detects that the second operation is performed within a predetermined time after the first operation is performed as the prescribed operation.
That is, the prescribed operation is preferably an operation within a predetermined time obtained by combining a plurality of operations. For example, it may be determined that the prescribed operation has been performed when the signal transmission operation is detected within a predetermined time after the insertion operation is detected. Alternatively, when the insertion operation is detected within a predetermined time after the signal transmission operation is detected, it may be determined that the specified operation has been performed.
Since the insertion operation is an operation performed by the user outside the vehicle, it is preferable that the signal transmission operation is also an operation performed by the user outside the vehicle. Thereby, a series of the prescribed operations are performed outside the vehicle, and the operability is improved.

  (3) In the prescribed operation, it is preferable that one of the insertion operation and the signal transmission operation is the first operation, and the other is the second operation. For example, when the signal transmission operation is performed within a predetermined time after the insertion operation is performed, it may be determined that the prescribed operation has been performed. Alternatively, it may be determined that the prescribed operation has been performed when the insertion operation is performed within a predetermined time after the signal transmission operation is performed.

(4) The prescribed operation is an input operation to a first input device provided in the vehicle or an input operation to a second input device built in a portable device possessed by a user of the vehicle. It is preferable to include.
Specific examples of the first input device include a car navigation device, a touch panel of a meter display device, an operation input button, and the like. Specific examples of the second input device include touch sensors and operation input buttons provided on electronic keys (keyless entry keys, KOS keys (keyless operation system keys), etc.).

(5) It is preferable that the specified operation includes a switching operation for switching an operating state of the door lock device of the vehicle.
The switching operation includes a pressing operation (touch operation) on the door lock button of the door handle, and includes a pressing operation (touch operation) on the lock button and lock release button of the electronic key. Moreover, it is preferable to set the number of switching operations to a plurality of times in order to distinguish from normal locking operations and unlocking operations.

( 6 ) It is preferable to provide the memory | storage part which memorize | stores said 1st charging rate and said 2nd charging rate so that overwriting is possible. That is, it is preferable that the first charging rate and the second charging rate can be arbitrarily changed by a user of the vehicle.
In this case, for example, the first charging rate may be a charging rate that can be freely set by the user, and the second charging rate may be a preset charging rate (default charging rate). Conversely, the first charging rate may be a preset charging rate, and the second charging rate may be a charging rate at which the user can freely set.

  According to the disclosed charging control device, the upper limit charging rate of the external charging can be easily changed by performing the prescribed operation including the insertion operation of the charging gun, and the convenience of the external charging can be improved. . Further, for example, it is not necessary to call a setting screen for setting the charging rate upper limit value from a menu screen of a vehicle meter system or a car navigation system, and usability can be improved.

[1. vehicle]
A vehicle 10 shown in FIG. 1 is an electric vehicle (an electric vehicle, a plug-in hybrid vehicle, or the like) equipped with a battery 1 for driving the vehicle. The battery 1 is a secondary battery that can be charged by an external power source outside the vehicle, and for example, charging using a home AC power source (normal charging) or charging using a high-voltage DC power source (rapid charging) is possible. . The electric power supplied from the external power source is charged to the battery 1 via, for example, an in-vehicle charger. A charging station 11 in FIG. 1 is an example of an external power supply outside the vehicle, and is a power supply device (public charging facility) for rapid charging.

  Two types of connectors 8 and 9 are provided on the outer surface of the side surface of the vehicle 10 as power inlets (charging ports) for connecting the charging gun 15 of the charging cable 14. The low-voltage connector 8 is a connector that is normally used for charging, and has a function of receiving, for example, a medium-low voltage (100 to 250 [V]) alternating current. On the other hand, the high-voltage connector 9 is a connector used for quick charging, and has a function of receiving a high-voltage (250 to 500 [V]) direct current, for example. The shapes of the connectors 8 and 9 and the charging gun 15 correspond to the standards and specifications for normal charging and quick charging.

  An insertion detection sensor 18 for detecting whether or not the charging gun 15 is inserted is provided in the vicinity of the low voltage connector 8 and the high voltage connector 9. Here, it is detected that the charging gun 15 is inserted into at least one of the connectors 8 and 9. At this time, the presence or absence of power supply from the charging cable 14 is unquestioned. The presence / absence of insertion of the charging gun 15 can be detected by switching the connection / disconnection state of the contact type switch in accordance with the insertion state of the charging gun 15.

  A door lock device 6 is built in the door of the vehicle 10, and a door lock button 7 for switching the locked / unlocked state between the locked state and the unlocked state is provided on the door handle. The locked / unlocked state is electrically controlled via a body-type electronic control device. The door lock device 6 is compatible with a keyless entry system, and has a function of switching the locking / unlocking state by wireless communication with the electronic key 12. The electronic key 12 is a portable device possessed by a user of the vehicle 10 and is provided to a regular occupant (user, owner) who drives the vehicle 10. By operating the key lock button 13 of the electronic key 12, the lock / unlock state of the door lock device 6 can be switched.

  A meter display device 16 is mounted in the passenger compartment of the vehicle 10. The meter display device 16 is an electronic device including a general-purpose video display device (display screen) and an electronic control device (computer) including a CPU (microprocessor), ROM, RAM, and the like. On the surface of the video display device, a touch panel 17 is built in as an operation input device for the electronic control device. The meter display device 16 is connected to a car navigation system, a car audio system, an air conditioning system, a multimedia system, and the like mounted on the vehicle 10.

  A battery control device 2 (charging control device) that controls the charging state of the battery 1 is provided at an arbitrary position of the vehicle 10. The battery control device 2 is an electronic control device that controls various types of control relating to charging / discharging of the battery 1. For example, as shown in FIG. 2, the battery control device 2 is an electronic device in which a CPU 21 (microprocessor), ROM 22, RAM 23 and the like are integrated. A door lock device 6, a meter display device 16, and an insertion detection sensor 18 are connected to the battery control device 2. Information about the presence / absence of an input operation to the door lock button 7, the key lock button 13, and the touch panel 17 and the presence / absence of an insertion operation of the charging gun 15 are transmitted to the battery control device 2.

[2. Battery control device]
[2-1. Overview]
In the battery control device 2, various controls relating to the battery 1 are performed, and the charging state of the battery 1, the battery temperature, the input / output current of the battery 1, the input / output voltage, the charging rate, etc. are grasped. In the present embodiment, upper limit value switching control that is performed when the battery 1 is charged with an external power source will be described. The upper limit value switching control is control for changing the upper limit charge rate of the battery 1 that is a condition for terminating external charging, and two types of upper limit charge rates are set in the battery control device 2. Hereinafter, each upper limit charging rate is referred to as a first charging rate and a second charging rate.

  In normal external charging, the state of charge is controlled so that external charging is completed when the charging rate of the battery 1 reaches one upper limit charging rate (second charging rate). On the other hand, when a prescribed operation different from the normal time is detected, the external charging is terminated when the charging rate of the battery 1 reaches the other upper limit charging rate (first charging rate), The state of charge is controlled. The “regulated operation” here means an operation of a pattern that is not performed during normal external charging, an insertion operation for inserting the charging gun 15 into the connectors 8 and 9 of the charging port of the vehicle 10, and a control signal to the vehicle 10. A plurality of operations including a signal transmission operation for transmitting the signal. Here, an example of setting the first charging rate and the second charging rate is illustrated in Table 1 below.

  In the above setting 1, the upper limit charging rate at the normal time is set to 90%, and the upper limit charging rate at the time of detecting the specified operation is set to 100%. This setting can be said to be a setting suitable for a user whose home is located on a hill or on a hill. This is because the charging rate of the battery 1 is expected to increase due to regenerative power generation on the downhill while going from the home to the destination. By selecting setting 1, the amount of charge in external charging using a household outlet is reduced, and regenerative braking performance and energy saving performance are improved. On the other hand, when returning from the destination to the home, the upper limit charging rate is switched to 100% by performing the prescribed operation, so that a sufficient amount of charge for returning home is secured.

  In the above setting 3, the upper limit charging rate at the normal time is set to 100%, and the upper limit charging rate at the time of detecting the specified operation is set to 90%. In contrast to setting 1, this setting can be said to be a setting suitable for a user whose home is located in a basin or lowland. In the above setting 2, the second charging rate is lowered to 80% compared to setting 1. Further, the above setting 4 is a saving of the first charging rate up to 80% than the setting 3.

  Here, the prescribed operation will be described in detail. The prescribed operation is one of the conditions for switching the upper limit charging rate of the battery 1 from the second charging rate to the first charging rate, and includes at least an insertion operation of the charging gun 15 and a signal transmission operation. Specific examples of this signal transmission operation include the following operations 1 to 4. For example, when an operation that combines the insertion operation of the charging gun 15 and at least one of the following operations 1 to 4 is performed within a predetermined time A, it is determined that “the prescribed operation has been detected”.

Operation 1: Input operation to the door lock button 7 (including pressing operation, touch operation, etc.)
Operation 2: Input operation to the key lock button 13 (including pressing operation, touch operation, etc.)
Operation 3: Input operation to the touch panel 17 (including pressing operation, touch operation, etc.)
Operation 4: Charging gun 15 insertion / extraction operation

[2-2. function]
The battery control device 2 is provided with a storage unit 3, a detection unit 4, and a control unit 5 as functional elements for performing the above upper limit value switching control. Each of these elements may be realized by an electronic circuit (hardware), may be programmed as software recorded and stored in the ROM 22, RAM 23, or an auxiliary storage device (not shown), or may have these functions. A part of them may be provided as hardware and the other part may be software. It is assumed that the storage unit 3, the detection unit 4, and the control unit 5 of the present embodiment are recorded and stored as a part of a program in the ROM 22 and the RAM 23. The functions of the storage unit 3, the detection unit 4, and the control unit 5 can be realized by causing the CPU 21 to read the program and executing arithmetic processing.

  The storage unit 3 stores the first charging rate and the second charging rate. For example, as shown in Table 1, a plurality of types of setting contents are recorded for combinations of the first charging rate and the second charging rate. Further, at least one setting content can be overwritten and changed. That is, both the first charging rate and the second charging rate can be changed to values according to the user's preference. A specific example of the element that stores the first charge rate and the second charge rate that can be overwritten is a nonvolatile memory (EEP-ROM or flash memory). Information on the first charging rate and the second charging rate recorded and stored in the storage unit 3 is transmitted to the control unit 5.

  The detection unit 4 detects the presence / absence of the prescribed operation. Here, it is determined whether or not an operation in which the insertion operation of the charging gun 15 and the signal transmission operation are combined within a predetermined time A. In the present embodiment, it is detected as a prescribed operation that an operation in which the first operation and the second operation are combined is performed within a predetermined time A. That is, the prescribed operation is set in advance as an operation including the first operation and the second operation. The first operation is an operation (measurement start operation) in which measurement of a predetermined time A for determining the presence or absence of a prescribed operation is started. On the other hand, the second operation is an operation within the predetermined time A, and is an operation (completion operation) for confirming whether or not the prescribed operation is present.

  When the first operation is detected, the detection unit 4 starts a timer and starts measuring time. Thereafter, when the second operation is detected before the predetermined time A has elapsed, it is determined that the prescribed operation has been performed. If the second operation is not detected before the predetermined time A has elapsed, it is determined that the prescribed operation has not been performed. Even when the first operation itself is not detected, it is determined that the prescribed operation has not been performed.

FIGS. 3A and 3B are graphs for explaining an example of detection of a prescribed operation including the operation 2. Here, it is assumed that the first operation is an insertion operation of the charging gun 15 and the second operation is a plurality of pressing operations to the key lock button 13. First, the insertion operation of the charging gun 15 is detected, the time t ₀ as a reference, the time measurement is started by a timer for measuring an elapsed time. Thereafter, when the key lock button 13 is pressed a plurality of times (for example, twice in succession) until the elapsed time exceeds a predetermined time A set in advance, the detection unit 4 indicates that “the prescribed operation has been detected”. And the information is transmitted to the control unit 5. On the other hand, if the key lock button 13 is not pressed twice within a predetermined time A, such as when the key lock button 13 is pressed only once to enter the vehicle from outside the vehicle, only the first operation is detected. Therefore, the detection unit 4 determines that “the prescribed operation is not detected” and transmits the information to the control unit 5.

  The order of the insertion operation and the signal transmission operation is not questioned. That is, when the insertion operation of the charging gun 15 is the second operation, the first operation is a pressing operation to the key lock button 13. On the contrary, when the signal transmission operation by the key lock button 13 is the first operation, the second operation is the insertion operation of the charging gun 15. In any case, when both the first operation and the second operation are detected, it is determined that the prescribed operation has been performed, and the upper limit charging rate is changed. For example, as shown in FIGS. 3C and 3D, when the key lock button 13 is pressed twice continuously before the charging gun 15 is inserted, the key lock button 13 is first pressed. The predetermined time A is measured with reference to the time point. In this case, if the insertion operation of the charging gun 15 is performed within the predetermined time A, the detection unit 4 may determine that “the prescribed operation has been detected”.

  The same applies to the detection of prescribed operations including operations 1, 3, and 4. That is, it is assumed that the measurement start operation is first performed by one of the insertion operations of the charging gun 15 and the set operations 1 to 4, and the elapsed time exceeds a preset predetermined time A. In the meantime, the completion operation is performed by the other operation, and the prescribed operation is detected by performing both operations. Note that what kind of signal transmission operation is used to determine the presence or absence of the prescribed operation may be set in advance or may be arbitrarily selected by the user. Also, the number of signal transmission operations is arbitrary, and is more preferably at least twice (multiple times) so that it can be easily distinguished from at least a normal door lock operation or unlock operation.

The control unit 5 is a main body that performs upper limit switching control. Here, the first charge rate is set to the upper limit charge rate of the battery 1 when the detection operation is detected by the detection unit 4 when the battery 1 is externally charged. However, the upper limit charging rate is set to the first charging rate only once, and only the external charging immediately thereafter is set. That is, the upper limit value switching control is a control for temporarily canceling the normal setting with respect to the most recent charge with respect to the setting of the upper limit charge rate of the battery 1. Settings are used.
On the other hand, when the prescribed operation is not detected, the second charging rate is set to the upper limit charging rate of the battery 1. The external charging is continued until the charging rate of the battery 1 reaches the upper limit charging rate set here, and ends when the charging rate of the battery 1 reaches the upper limit charging rate.

[3. flowchart]
FIG. 4 is a flowchart illustrating the procedure of the upper limit value switching control, which is repeatedly executed in the battery control device 2 at a predetermined calculation cycle. Here, although the prescribed operation includes operation 2, other operations 1, 3, and 4 may be naturally performed.
In step A1, it is determined whether or not the charging gun 15 is inserted. Whether or not the charging gun 15 is inserted can be determined based on information transmitted from the insertion detection sensor 18. If insertion is detected here, it is determined that a measurement start operation has been performed by inserting the charging gun 15, and the process proceeds to step A3, where measurement for a predetermined time A is started. On the other hand, if no insertion has been detected, the process proceeds to step A2.

  In step A2, it is determined whether or not the key lock button 13 has been pressed. If a pressing operation is detected here, it is determined that a measurement start operation has been performed, and the process proceeds to step A3, where measurement for a predetermined time A is started. On the other hand, if no pressing operation has been detected, no operation has been performed yet, so the control in the current calculation cycle is terminated. In the next calculation cycle, control is started again from step A1.

  In step A4 following step A3, it is determined whether or not the prescribed operation has been detected by the detection unit 4. When the condition of step A1 has already been established, measurement by a timer is started and a completion operation waiting state is entered, as shown in FIG. In this case, it is determined whether or not the key lock button 13 is pressed twice continuously as a completion operation within the predetermined time A. If the condition of step A2 has already been established, it is determined whether or not the insertion operation of the charging gun 15 has been performed as a completion operation within a predetermined time A as shown in FIG. . When these conditions are met, control proceeds to step A6.

  In step A <b> 6, the first charging rate is set to the upper limit charging rate of the battery 1 in the control unit 5. That is, the upper limit charging rate is switched from the normal second charging rate to the first charging rate. Therefore, the external charging started after that ends when the charging rate of the battery 1 reaches the first charging rate.

  If the determination in step A4 is not established, the process proceeds to step A5, where it is determined whether the predetermined time A has elapsed, and until the predetermined time A elapses, the completion operation is waited. Repeatedly. If the predetermined time A has elapsed (timed out), the process proceeds to step A7, where the control unit 5 sets the second charging rate to the upper limit charging rate of the battery 1. That is, when the predetermined time A has passed without detecting the prescribed operation, such as when the charging gun 15 is left inserted, external charging is performed at the normal upper limit charging rate.

[4. Action, effect]
(1) In the battery control device 2 described above, when the battery 1 is externally charged, the detection unit 4 detects the presence or absence of the prescribed operation. The prescribed operation here is defined as a combination of a plurality of operations including an insertion operation of the charging gun 15 and a signal transmission operation for transmitting a control signal to the vehicle 10. Therefore, for example, it is easy to distinguish from normal external charging operations (charging lid opening / closing operation, charging gun 15 simple insertion operation, etc.), but the specified operation is given a specific meaning and the “control command” Can be used.

  In addition, the meaning of “control command” in the present embodiment is interpreted by the control unit 5 as a command for starting “upper limit switching control”. Thereby, the charge upper limit value of the battery 1 in external charging can be temporarily changed, and convenience related to external charging of the vehicle 10 can be enhanced. For example, when the external charging from a household outlet is used, the first charging rate is used and when the remote charging is performed remotely, the second charging rate is used. Can be used properly.

Thereby, the charging rate when the battery 1 is fully charged becomes the charging rate desired by the user, and usability can be improved. Moreover, since the termination conditions for external charging are changed, for example, the charging time can be shortened by lowering the upper limit charging rate.
Further, for example, it is not necessary to call a setting screen for changing the setting of the charging rate upper limit value from the menu screen of the meter display device 16 of the vehicle 10, and usability can be improved.

(2) In the battery control device 2 described above, when the second operation is performed within a predetermined time A after the first operation is performed, it is determined that the specified operation has been performed. Thus, erroneous determination can be prevented by determining the time during which the presence / absence of the prescribed operation is determined.
(3) In the battery control device 2 described above, the first operation and the second operation can be exchanged as shown in FIGS. 3 (A) and 3 (B) and FIGS. 3 (C) and 3 (D). Yes. For example, when the prescribed operations are “insertion operation of the charging gun 15” and “double press operation of the key lock button 13”, the user can perform the operation within a predetermined time A without worrying about the order of these operations. A specified operation can be input. Thus, by providing flexibility to the determination criteria, convenience can be improved and a service that is easy to use for the user can be provided.

(4) The above-mentioned prescribed operation includes an input operation (operation 3) to the touch panel 17 of the meter display device 16 provided in the vehicle interior of the vehicle 10. Accordingly, the user can start the upper limit value switching control with a simple operation from the passenger compartment, and the convenience can be improved.
Further, the above-mentioned prescribed operation includes an input operation (operation 2) to the electronic key 12. Thereby, the user can perform a prescribed operation when connecting the charging gun 15 to the vehicle 10, and convenience can be improved.
If both of the above operations 2 and 3 are adopted as specified operations, the user can start the upper limit value switching control regardless of where the vehicle is inside or outside the vehicle after inserting the charging gun 15 into the connectors 8 and 9. , Convenience can be further improved.

(5) The prescribed operation includes a switching operation (operation 1, operation 2) for switching the operation state (locking / unlocking state) of the door lock device 6. Thereby, regulation operation can be performed outside the vehicle 10, and the convenience can be improved.
In a normal locking operation, the door lock button 7 and the key lock button 13 are not continuously operated over a plurality of times. Therefore, by including the input operation (including pressing operation, touch operation, etc.) to the door lock button 7 and the key lock button 13 several times in the specified operation, the normal locking operation and the specified operation can be accurately distinguished. It is possible to avoid erroneous determination.

  (6) The battery control device 2 is provided with the storage unit 3 that stores the first charging rate and the second charging rate in an overwritable manner. Thereby, not only can the two types of upper limit charging rates be switched, but the upper limit charging rate during normal operation (default charging rate) can also be changed according to the user's preference. Therefore, the convenience regarding external charging of the vehicle 10 can be further enhanced.

[5. Modified example]
Regardless of the embodiment described above, various modifications can be made without departing from the spirit of the invention. Each structure of this embodiment can be selected as needed, or may be combined appropriately. In the above-described embodiment, as shown in FIGS. 3A and 3B, the detection example of the regulation operation including the operation 2 has been described. However, when the regulation operation including the operation 4 is detected, the charging gun 15 is detected. It is conceivable to determine the insertion / extraction state.

  For example, as shown in FIG. 5, the insertion / extraction operation of the charging gun 15 is repeated a predetermined number of times or more as a completion operation within a predetermined time A with reference to the time when the insertion operation of the charging gun 15 is detected as the measurement start operation. In this case, it may be determined that “the prescribed operation has been detected”. Alternatively, when an operation for removing the charging gun 15 is detected after the insertion operation of the charging gun 15 is detected, and then the charging gun 15 is inserted into the connectors 8 and 9 again, the “specified operation is detected”. You may judge. Thereby, the user can start the upper limit switching control only by inserting and removing the charging gun 15, and usability (ease of use) can be further improved. Further, input operations such as the door lock button 7 and the key lock button 13 are not required for control, and the control configuration can be simplified and the cost can be reduced.

  A combination of operations 1 to 4 may be a signal transmission operation. For example, as shown in FIGS. 6A to 6C, both the key lock button 13 and the door lock button 7 are pressed within a predetermined time A from when the insertion operation of the charging gun 15 is detected. When it is done, it may be determined that “the prescribed operation has been detected”. The specific signal transmission operation and the specified operation are not limited to the operations described in the above embodiment.

  In the above-described embodiment, as shown in Table 1, one of the first charging rate and the second charging rate is set to 100%, but the first charging rate and the second charging rate are shown. The specific value of can be arbitrarily set. That is, it is not always necessary to set one side to 100%. By preparing at least two types of upper limit charging rates having different values and using them in accordance with the presence / absence of the prescribed operation, it is possible to achieve control that provides the same effect as that of the above-described embodiment.
