Description

BACKGROUND OF THE INVENTION 1. Field of the invention

[0001] The invention relates to a charging device for a vehicle on which an electrical storage device is mounted, and in particular to a charging device for a vehicle that performs timer charging or timer-controlled charging. 2. Description of related technology

[0002] In recent years, vehicles such as electric vehicles and plug-in hybrid vehicles, which are designed to be able to charge an electrical storage device mounted on the vehicle from an external device, have begun to be used on a large scale.

[0003] Japanese patent application publication no. 2012-70623 (JP 2012-70623 A) describes a control device for a vehicle that is capable of adjusting or setting a charging scheme or charging plan for charging an electrical storage device from an external power supply.

[0004] An electrical control unit (ECU) mounted on the vehicle and described in this publication comprises a charging control unit, which causes a battery to be charged by controlling a charger or charging device, and a start-up command unit, which, when a charging start time is set, issues a start command to the charging control unit, causing the charging control unit to wait until the current time reaches the charging start time and to begin charging the battery from that time. Upon receiving a start command, the start command unit issues the start command to the charging control unit, causing the battery to begin charging from the moment the start command is received.

[0005] JP 2012-70623 A describes that the start command unit performs a control such that the battery begins to be charged from the moment the start command is received; however, it obviously does not describe the details of an actuation by a user for the output of the start command to the start command unit.

[0006] It can be assumed that the frequency with which a command to delete such a timer reservation or a command to enable a timer reservation is issued, depending on the user's usage pattern, is extremely low. For example, a user performing a normal charge without a timer setting, or a user who consistently performs a timer charge in accordance with a timer setting, will issue such a command extremely rarely.

[0007] This means that the frequency with which an input switch is activated to output a command is also low, making it difficult for the user to detect or realize any abnormality, even if the switch is faulty. Therefore, if the timer is set and an immediate load is intended by clearing the timer setting, there is a risk that the timer setting cannot be cleared and the immediate load cannot be performed. SUMMARY OF THE INVENTION

[0016] In the charging device, the electronic control unit can be configured to use the switch as a switch for initiating the locking mechanism to lock the charging cable immediately after the charging cable is connected to the inlet or port, and the electronic control unit can be designed to control the charger such that the charger performs timed charging or time-controlled charging when the switch is actuated within a predetermined time period from the time at which the locking mechanism is first put into a locked state after the charging cable is connected to the inlet or port.

[0017] In the charging device, the electronic control unit can be designed to use the switch as a switch for initiating the locking mechanism to lock the charging cable immediately after the charging cable is connected to the inlet or connector, and the electronic control unit can be configured to control the charger such that the charger performs immediate charging if the switch is not actuated within a predetermined time period from the time at which the locking mechanism is placed in a locked state for the first time after the charging cable is connected to the inlet or connector.

[0018] In the charging device, the electronic control unit can be configured to use the switch as a switch for initiating the locking mechanism to lock the charging cable immediately after the charging cable is connected to the inlet or connector, and the electronic control unit can be configured to control the charger such that the charger performs immediate charging when the switch is actuated within a predetermined time period from the moment the locking mechanism is first placed in a locked state after the charging cable is connected to the inlet or connector.

[0019] In the charging device, the electronic control unit can be configured to use the switch as a switch for initiating the locking mechanism to lock the charging cable immediately after the charging cable is connected to the inlet or connector, and the electronic control unit can be configured to control the charger such that the charger performs timed charging or time-controlled charging if the switch is not actuated within a predetermined time period from the time at which the locking mechanism is first placed in a locked state after the charging cable is connected to the inlet or connector.

[0020] In accordance with the invention, it is possible to increase the likelihood that an error in a timer setting for charging is detected and that switching between activated and deactivated states of a timer is performed during a charging process without any cumbersome burden being placed on the user.

The ECU 170 receives signals from an autolock or self-locking adjustment unit 270 , the timer charge setting unit 176 , the charging cable connection detection circuit 312 , a lid open / close detection unit 502 and the switch 177 Additionally, the ECU controls 170 the charging indicator 178 and the cable locking mechanism 260 . The desk 177is used to operate the cable locking mechanism 260 to be activated. Additionally, the switch 177 also used to activate or deactivate the charging start time set by the timer charging setting unit 176 is set or determined.

[0077] If the switch 177 When the device is in the switched-off state, a high-level signal is sent to the ECU. 170 due to a pull-up resistance or pull-up resistance 179 entered. If the switch 177 When the device is in the switched-on state, a low-level signal is sent to the ECU. 170 entered.

[0078] In Fig. 4. The polarity of the on / off state of the switch can also be inverted or reversed. Furthermore, according to Fig. 4 the pull-up resistance or pull-up resistance 179planned. However, it is also possible that instead of the pull-up resistance, an up-resistance is used. 179 a step-down resistor or pull-down resistor is connected and the configuration is changed such that instead of a ground potential, a voltage source potential or voltage supply potential Vcc is supplied when the switch is in the on state.

[0079] Fig. Figure 5 shows an external appearance of the charging cable unit. As in Fig. As shown in section 5, the charging cable unit 300 the connector 310 , the plug 320 , the CCID 330 and the cable 340 up. The connector 310 has a release button 314 , a suitable section or passage section 315 , which is connected to the entrance or connection 250 is adapted to the vehicle, and includes an intervening section or intervention section. 316 on.

[0080] The pass section 315 It features multiple terminals or connections (not shown). If the passport section 315 into the entrance or connection 250 of the hybrid vehicle 10 Once inserted, the voltage wire pair and the signal wire of the charging cable unit are connected to the vehicle. The intervention section 316 is used to connect the connector 310 to fix in a state where the connector 310 with the entrance or connection 250 is connected to the vehicle. The intervention section 316 moves in response to the release button being pressed 314 .

[0081] Fig. Figure 6 shows a view illustrating the configuration of an inlet or connection receiving section in which the inlet is received or housed. As in Fig. The section shown in 6 is the admission section. 254normally through a charging port 252 It is covered and not visible from the outside. The entrance section 254 takes the entrance or connection 250 , the charge indicator 178 , the switch 177 for locking the charging cable, a body section 262 and a pole 261 the cable locking mechanism 260 inside or within the charging port cover 252 on.

[0082] A push-button switch is in Fig. 6 as the switch 177 shown; instead, a contactless switch such as a proximity switch can be used.

[0083] As in Fig. 4 and Fig. As shown in section 6, the timer charging unit has 176For example, it features an input button or a touch-sensitive panel, allowing the input of a charging start or end time. The aforementioned timer charging setting unit 176 It is preferably installed, for example, near a driver's seat inside a vehicle cabin, as costs increase if a waterproof component is used. For example, a touch-sensitive panel or touch panel of a vehicle navigation system, a meter or instrument panel, a mobile terminal, or similar device could serve as the timer charging unit. 176 operate or function.

[0084] In contrast, even if a position is not specifically limited, it is as long as the charge indicator 178 which can be seen at the time when the charging cable is inserted into the inlet or port. 250 When introduced, the charging indicator will be 178preferably close to the entrance or connection 250 It is installed in such a way that it is easily visible from the outside of the vehicle. Furthermore, the switch 177 The locking mechanism for the charging cable is usually activated immediately after the charging cable is connected to the inlet or port, so that the switch... 177 near the entrance or connection 250 is installed.

[0085] If we assume here that the charging cable is connected to the inlet or port... 250 If the device is connected outside the vehicle to charge the vehicle, but the timer setting is incorrectly configured, it is very disadvantageous if it becomes necessary to adjust the timer charging setting unit. 176 The timer setting must be operated or activated inside the vehicle cabin, as the user needs to return to the vehicle cabin.

[0086] Furthermore, depending on the user's usual way of using the vehicle, it can be assumed that the operation to reset the timer setting is rarely performed. In such a case, even if the reset switch is faulty, it is difficult for the user to detect the fault, and it can be assumed that the user will not find the fault until they intend to perform an immediate charge by actuating the switch.

[0087] In the present embodiment, the switch serves as 177for locking the charging cable also as the switch for clearing the timer setting, focusing on the point that the switch for clearing the timer setting is located in a position where the switch can be easily operated outdoors, and on the point that a switch which is frequently used and where a fault is immediately and easily recognizable also serves as the clearing switch.

[0088] Fig. Figure 7 shows a view of the configuration to illustrate a configuration related to connecting the charging cable unit connector to the vehicle's inlet or port. As shown in Fig. As shown in 7, the connector 310 a suitable section or passage 315 , a locking mechanism 313 , the release button 314 , the charging cable connection detection circuit 312, the ground line or ground wire 342 and the signal line or signal cable 344 on.

[0089] For the purposes of simplifying the description, the voltage line pair 341 in Fig. 7 not shown. The locking mechanism 313 indicates the intervention section 316 , a rotatable shaft or a rotatable shaft 317 , the one or the one with the intervention section 316 is connected, and a spring 318 on, which is related to the intervention section 316 is connected. A step or a stage. 250A is in the entrance or connection 250 trained. The intervention phase 316 has a hook-shaped distal end section 316A and a rear end section 316B on. The axis of rotation or rotating shaft 317extends in a direction perpendicular to a direction (a direction indicated by arrow A in the drawing) in which the pass section 315 with the entrance or connection 250 is connected or will be connected to the inlet or connection 250 is separated.

[0090] The charging cable connection detection circuit 312 has a button or key 351 , a connection or a terminal 352 , which is connected to the signal line 344 is connected, a port or terminal 353 , the one connected to the ground wire 342 connected, a movable piece 354 for connecting the terminals 352 , 353 together, and a feather 355 for the movement of the movable part 354 on.

[0091] If the connector 310 with the entrance or connection 250the vehicle is or will be connected to the passport section 315 into the entrance or connection 250 introduced. Furthermore, the distal end segment occurs. 316A of the intervention section 316 with the level 250A in intervention, which in the inlet or connection 250 is trained. Consequently, it is possible to use the connector. 310 to fix in a state where the connector 310 with the entrance or connection 250 is connected. By pressing down the release button. 314 The distal end section moves along the direction of arrow B. 316A of the intervention section 316 away from the entrance or connection 250 Consequently, the intervention section 316 released from a state in which the intervention section 316 with the entrance or connection 250 is undergoing intervention.

[0092] The button or knob 351 the charging cable connection detection circuit 312 is through the rear end section 316B of the intervention section 316 pressed. The charging cable connection detection circuit 312 enters the open state when the button or knob is pressed. 351 is pressed or is, whereas the charging cable connection detection circuit 312 enters the closed state when the button 351 is not pressed. If the button 351 When not pressed, the moving part contacts 354 the connection 352 and the connection 353 due to the spring 355 Consequently, the charging cable connection detection circuit is activated. 312 into or assumes the closed state. If the button on the other side is pressed... 351 The movable part is pressed or will be pressed, is or will be pressed 354 from the connection 352and the connection 353 due to the key 351 moved away. Consequently, the charging cable connection detection circuit is activated. 312 is in the open state or is in this state.

[0093] The vehicle features a cable locking mechanism. 260 on, which is controlled by the ECU 170 it is activated here. The cable locking mechanism 260 The pole points 261 and the body part 262 for the movement of the rod 261 up. If the cable locking mechanism 260 When activated, the body section 262 the rod to protrude or reach the state indicated by the dashed line. In a state where the rod 241 The preceding section will involve a movement of the intervention section. 316 prevents the charging cable from coming out of contact with the inlet or port. 250can be accessed. Furthermore, the cable locking mechanism... 260 the locking of the cable by a control system on the part of the ECU 170 free. In this case, the body section looks 262 the pole 261 and returns it to the state indicated by the solid line. A direction in which the rod 261 moved, is a direction perpendicular to the direction (i.e., the direction indicated by arrow A in the drawing) in which the pass section 315 with the entrance or connection 250 is connected or will be connected or is separated or will be separated from it.

[0094] Furthermore, the vehicle has the ground wire 192 , which is connected to the ground wire 342 of the connector 310 is connected, and the signal line 194 on, which is connected to the signal line 344 of the connector 310 is connected. If the signal line194 with the signal line 344 When connected, the PISW signal is received from the connector. 310 to the ECU 170 transmitted.

[0095] The user is permitted to specify or decide whether a self-locking mechanism should be applied when the cable locking mechanism is actuated, by using the self-locking adjustment unit. 270 , which in Fig. Figure 4 shows that when a self-locking mechanism is engaged, the cable locking mechanism is automatically activated when the user connects the cable to the inlet or port, and the charging cable is locked in a position where it cannot be disconnected from the inlet or port. The self-locking adjustment unit 270It does not necessarily always have to be provided, and it can be determined by setting at the time of product design or in a factory, as needed, whether a self-locking mechanism is used or provided in the loading system, or whether a system is provided in which no self-locking mechanism is used.

[0096] Fig. Figure 8 shows a flowchart illustrating a control system for switching between the activated and deactivated states of the timer, in accordance with the first embodiment. This process occurs when a self-locking mechanism is set. As in Fig. As shown in 8, the ECU determines 170 Initially, when the process is started, in step S1, it checks whether the charging cable is connected. The ECU 170is able to determine, based on the PISW signal or the CPLT signal, whether the cable is connected or plugged in.

[0097] If step S1 fails to detect the presence of a cable connection, the process remains at step S1 and enters a detection wait state. At step S1, the ECU proceeds 170 Then, once it has been detected that the cable is connected, the process continues to step S2.

[0098] In step S2, the ECU determines or ascertains 170 , whether the timer's charging start time is controlled by the timer charging setting unit 176 , which in Fig. As shown in Figure 4, the timer has been preset or fixed. If the timer has not yet been set or configured in step S2, the process continues to step S6, where the cable is secured by the cable locking mechanism. 260due to a self-locking process, it is locked, and charging starts immediately.

[0099] Once the charging start time of the timer on the other side has been set in step S2, the process proceeds to step S3. In step S3, the system waits for a predetermined period of time while the timer is determined. This predetermined period is, for example, 10 seconds and can be adjusted as needed. This waiting time allows charging to begin for a while after the charging cable is connected to the inlet or port. 250 not started immediately, so that the number of times, or the number with which the relay is activated in the charging path, is not unnecessarily increased, and it is possible to extend the lifespan of the relay.

[0100] In the following step S4, it is determined whether the switch 177within the predetermined time period during which the timer determination is awaited in step S3. If it is determined in step S4 that the switch is activated. 177 Once activated, the process or sequence continues to step S6, where the cable is routed through the cable locking mechanism. 260 It locks due to a self-locking process, and charging begins immediately.

[0101] If, on the other hand, it is determined in step S4 that the switch 177 If the cable is not activated or has not been activated within the predetermined time period, the process proceeds to step S5, where the cable is secured by the cable locking mechanism. 260 It locks due to a self-locking process, and it allows the ECU 170a timer setting, and enters a standby state without charging until the set charging start time is reached.

[0102] After the process or procedure of step S5 or step S6, the switch operates. 177 as a cable release switch for unlocking the cable. This means that in one step S7, the detection of an actuation of the switch is triggered. 177 The process is being monitored and, if the activation has been detected, the process or operation progresses to step S8, and the ECU 170 a control system to operate the cable locking mechanism 260 to cause the cable to unlock, after which the process ends in step S9. It is also desirable that charging be stopped if the cable is unlocked.

[0103] The special feature of the process at the point when a self-locking mechanism is used, as in Fig. As shown in Figure 8, the cable locking mechanism consists of... 260 is in a state releasing the locking mechanism (unlocked state) prior to a timer determination or setting, and that the switch 177 It acts as a switch for instant charging when the cable locking mechanism is engaged. 260 in the unlocked state. Furthermore, even if the switch 177 is activated in a state where the charging cable is not connected to the inlet or port. 250 Once connected, the system will detect that commands for an immediate reload (timer reset) have been entered. In this case, a timer reset specification can be deleted until the cable is connected within the predetermined time period (e.g., one minute).

[0104] The following considers the case where the switch 177has an error. In the process or procedure that goes into Fig. As shown in Figure 8, the immediate loading (timer clearing) does not work if the switch is 177 The device has a fault, and the charging cable cannot be unlocked. Unlocking the charging cable is usually disabled in cases where the vehicle is controlled in such a way that it is not allowed to move, in order to prevent the cable from being pulled or dragged. This allows the user to detect the faulty switch. 177 to realize or recognize immediately.

[0105] If the switch 177If the vehicle has a fault, it is conceivable to allow it to be driven to a repair shop by designing the vehicle in such a way that the cable can be forcibly unlocked. In this case, a self-locking mechanism and a timer setting to a deactivated state should be controlled at the time of the forcible unlocking, as a condition exists in which it is not possible to unlock the cable normally or to perform immediate charging.

[0106] If such a forced unlocking process has been performed three times consecutively during charging, a self-locking mechanism and a timer setting can subsequently be controlled to the deactivated state, even if a forced unlocking is not performed. In such a case, the user is informed of the possibility that the switch 177If an error is detected, the timer setting is disabled, and an immediate load is allowed. This avoids the disadvantage of not being able to perform an immediate load.

[0107] However, it is difficult to strictly distinguish between a forced unlocking operation performed by the user (faulty actuation at a time when the system is normal) and a fault of the switch. 177 to distinguish, so that it is desirable that an error is not recorded and that a timer setting is returned to the activated state, with the timing or temporal position at which an actuation of the switch occurs. 177 through the ECU 170 had been recognized.

[0108] The following describes the case where a self-locking mechanism has not been set. Fig. Figure 9 shows a view illustrating a state transition in the case where a self-locking mechanism has not been set or adjusted and the timer has been set.

[0109] As in Fig. As shown in 9, this occurs when the switch 177 When activated in an initial state ST0, a transition to a state ST1 occurs, and the cable locking mechanism is engaged. 260 The switch is activated and placed in a cable locking state. State ST1 occurs when the switch is activated. 177 If a further detection is detected, a transition to state ST2 occurs. In state ST2, any setting of the timer is deactivated, and immediate charging begins. In state ST2, the following occurs when the switch is activated: 177 If a fault is detected, a transition to state ST3 occurs. In state ST3, the cable locking mechanism is activated.260 changed to an unlocked state. In state ST3, a transition to state ST1 occurs when the switch is actuated. 177 has continued to be detected.

[0110] At this point, the ECU can 170 Implement a control system such that the timer enters state ST1 in response to the activation of the switch. 177 When a trigger is reset (the timer is activated), the timer setting is disabled in state ST2, and charging is paused or terminated in state ST3. However, pausing charging and resetting the timer may require the insertion or disconnection of the cable to or from the inlet or connector. 250 use it as a trigger.

[0111] Fig. Figure 10 shows a view illustrating a transition of the state or status in the case where self-locking is not set and the timer is not set. As in Fig. As shown in 10, this occurs when the switch 177 When ST10 is activated in an initial state, a transition to state ST11 occurs, and the cable locking mechanism is activated. 260 The switch is activated and placed in a cable-locked state. State ST11 occurs when the switch is activated. 177 If a fault is detected, a transition to state ST12 occurs. In state ST12, the cable locking mechanism is activated. 260 changed to an unlocked state. In state ST12, a transition to state ST11 occurs when the switch is actuated. 177 has continued to be detected.

[0112] At this point, charging to state ST11 can be synchronized with an actuation of the switch. 177 It can be started (resumed if temporarily interrupted). However, the switch can 177 It may not be used directly as a trigger to start or stop charging. A connection detection signal from the charging cable can be used as a trigger.

[0113] Fig. Figure 11 shows a flowchart illustrating how the ECU uses the switch in different ways in accordance with an alternative embodiment as an alternative to the first embodiment. As in Fig. 4, Fig. 6 and Fig. As shown in 11, the ECU determines or ascertains 170 Initially, when the process is started, in step S11, it checks whether the charging cable is connected to the inlet or port. 250 is connected. The ECU 170is able to, based on the state of the PISW signal or the CPLT signal, which is in Fig. Figure 3 shows whether the charging cable unit 300 is connected.

[0114] If in step S11 it is determined that the charging cable unit 300 not with the entrance or connection 250 Once connected, the process or operation proceeds to step S12, and it uses the ECU. 170 the switch 177 as a switch for instant charging (switch to disable a timer setting).

[0115] If step S11 determines that the charging cable unit 300 with the input or connection 250 Once connected, the process proceeds to step S13. In step S13, the ECU uses 170 the switch 177as a switch for changing between locking / unlocking or as a locking / unlocking toggle switch.

[0116] After the execution of the process according to step S12 or step S13, the process or sequence proceeds to step S14, and the process returns to a main routine.

[0117] As described above, the use of the switch 177 based on whether the charging cable is connected to the inlet or port.

[0118] Next, a second embodiment is explained. The first embodiment describes an example where the cable locking switch is also used as a timer reset switch. In this case, the charging system is designed or configured to perform a timer charge or time-controlled charge when the timer time is set, unless otherwise specified.

[0119] However, it can be assumed that, depending on the user, the frequency with which a timer charge is performed is low. The second embodiment describes the case in which the charging system is designed or configured such that a timer charge is not performed, even if the timer time has been set, unless otherwise specified, and such that the timer charge is only performed when a process to activate the timer is carried out. In such a case, a switch for enabling or activating the timer (hereinafter referred to as a timer setting switch) is required instead of the timer reset switch.

[0120] The in Fig. 1 to Fig. The five configurations shown are also the same as in the second embodiment. However, the way the switch is used is different. 177 different with regard to the setting of the timer.

[0121] Fig. Figure 12 shows a flowchart illustrating a control system for switching between the activated and deactivated states of the timer, in accordance with the second embodiment. This process is for the case where a self-locking mechanism is set. As in Fig. As shown in 12, the ECU determines 170 Initially, when the process is started, in step S21, it checks whether the charging cable is connected. The ECU 170 is able to determine whether the cable is connected based on the PISW signal or the CPLT signal.

[0122] If no cable connection is detected in step S21, the process remains at step S21 and enters a detection wait state. In step S21, the ECU proceeds 170 Then, if a connection of the cable has been detected, the process continues to step S22.

[0123] In step S22, the ECU determines 170 , whether the timer's charging start time is controlled by the timer charging setting unit 176 , which in Fig. As shown in step 4, the timer has been preset. If the timer is not set in step S22, the process continues to step S26, where the cable is connected through the cable locking mechanism. 260 It locks, and charging starts immediately.

[0124] If the charging start time of the timer has been set in step S22, the process proceeds to step S23. In step S23, the system waits for a predetermined time period or duration for the activation to determine the timer. The predetermined duration is, for example, 10 seconds and can be adjusted as needed. This waiting period prevents charging from starting immediately after the charging cable is connected to the inlet or port. 250 is connected so that the number or frequency with which the relay is activated in the charging path does not need to be unnecessarily increased, and it is therefore possible to extend the lifespan of the relay.

[0125] In the following step, S24 is determined, or rather, ascertained, whether the switch 177within the predetermined time period during which the timer determination or setting process in step S23 is awaited. If the switch 177 If step S24 is not activated, the process proceeds to step S26, where the cable is routed through the cable locking mechanism. 260 Due to the self-locking process, it locks, and charging starts immediately.

[0126] If the switch 177 On the other side, if step S24 is activated within the predetermined time period, the process proceeds to step S25, where the cable is routed through the cable locking mechanism. 260 locked due to a self-locking process, and the ECU 170It allows a timer setting for determining or defining a timer process or timer operation, and is put into a standby state without a charging process until the set charging start time is reached.

[0127] After the process of step S25 or step S26, the switch operates 177 as a cable release switch for unlocking the cable. This means that in one step S27, a detection of an actuation of the switch is required. 177 The process is being monitored and, if the activation has been detected, it proceeds to step S28, and it executes the ECU 170 a control unit for initiating the cable locking mechanism 260 to unlock the cable, after which the process ends in step S29. It is desirable that the waiting also ends when the cable is unlocked.

[0128] The characteristic of the process at the point when a self-locking mechanism is used, as in Fig. As shown in 12, the cable locking mechanism consists of 260 is in a state releasing the locking mechanism (unlocked state) prior to a timer determination or timer setting, and the switch 177 acts as a timer setting switch when the cable locking mechanism 260 in the unlocked state. Additionally, even if the switch is in the unlocked state, it is still possible to... 177 is activated in a state where the charging cable is not connected to the inlet or port. 250The system will recognize that commands for timer determination or timer settings have been entered once the cable is connected. In this case, the timer determination or timer setting specification can be deleted unless the cable is connected within the predetermined time period (e.g., one minute).

[0129] Next, we will consider the case where the switch 177 has an error. In the process or procedure that occurs in Fig. As shown in 12, it works when the switch is... 177If the device exhibits a persistent power-on or stuck-on error, immediate charging (timer reset) is not possible, and the charging cable is unlocked, resulting in charging being impossible. Such an error should be detected, and the user should be informed that charging is not possible. Since charging is disabled, the user is able to troubleshoot the switch's fault. 177 to be realized or recognized immediately. In the case of a permanent switch-off fault or stuck-off fault of the switch. 177 The timer operation cannot be carried out; however, in this case, charging is allowed, so the disadvantage for the user is less than in the case of a continuous power-on error.

[0130] The following describes the case where a self-locking or autolock mechanism is not set or configured. Fig. Figure 13 shows a flowchart to illustrate a first example of a process or sequence in the case where self-locking is not set, and shows how the ECU uses the switch in different ways. As in Fig. 4, Fig. 6 and Fig. As shown in 13, the ECU determines 170 Initially, when the process is started, in step S31, it checks whether the charging cable is connected to the inlet or port. 250 is connected. The ECU 170 is able to, based on the state of the PISW signal or the CPLT signal, as in Fig. 3 are shown to determine whether the charging cable unit 300 is connected.

[0131] If step S31 determines that the charging cable unit 300 not with the entrance or connection 250 Once connected, the process proceeds to step S32, and it uses the ECU. 170 the switch 177as a timer setting switch or timer setting switch (switch for allowing a timer setting).

[0132] If step S31 determines that the charging cable unit 300 with the entrance or connection 250 Once connected, the process proceeds to step S33. In step S33, the ECU uses 170 the switch 177 as a switch for changing between locking and unlocking or as a locking / unlocking toggle switch.

[0133] If the operation is carried out according to step S32 or step S33, the process continues to step S34, and the process returns to a main routine.

[0134] As described above, the use of the switch 177 based on whether the charging cable is connected to the inlet or port.

[0135] Furthermore, the following is made with reference to Fig. 14 described that the switch 177 The timer setting switch can only be used while waiting for a timer setting or timer adjustment process, and can be used as a lock / unlock toggle switch after a timer setting or timer determination process, or after charging has started. In this case, actuating the switch before connecting the cable should be ignored.

[0136] Fig. Figure 14 shows a flowchart for the instructions of a second example process for the case where self-locking is not set, and illustrates how the ECU uses the switch in different ways. As in Fig. 4, Fig. 6 and Fig. As shown in 14, the ECU determines 170Initially, when the process is started, in step S41, it checks whether the charging cable is connected to the input or port. 250 is connected. The ECU 170 is able to determine whether the cable is connected based on the PISW signal or the CPLT signal.

[0137] If no cable connection is detected in step S41, the process remains at step S41 and enters a waiting state. In step S41, the ECU proceeds 170 Then, if a connection of the cable has been detected, the process continues to step S42.

[0138] In step S42, the ECU determines 170 , whether the timer's charging start time is controlled by the timer charging setting unit 176 , which in Fig. As shown in step 4, the timer has been preset. If the timer has not been set in step S42, the process continues to step S46, and the timer setting is deactivated, so that loading starts immediately.

[0139] Once the charging start time of the timer has been set in step S42, the process proceeds to step S43. In step S43, the system waits for a predetermined period while the timer is determined or set. This predetermined period is, for example, 10 seconds and can be adjusted as needed. Because of this waiting time, charging does not start immediately for a while after the charging cable is connected to the inlet or port. 250has been connected so that the number of times the relay is actuated in the charging path does not need to be unnecessarily increased, and it is possible to extend the lifespan of the relay.

[0140] In the following step, S44 is determined to see if the switch 177 is actuated within the predetermined time period, while in step S43 an actuation of the timer setting is awaited. If the switch 177 If step S44 is not activated, the process proceeds to step S46, and the timer setting is deactivated, so that loading starts immediately.

[0141] On the other hand, the process continues to step S45 when the switch is turned on. 177 within the predetermined time period in step S44, and it activates the ECU. 170The timer is set and the device enters a standby state without charging until the set charging start time is reached.

[0142] After the process of step S45 or step S46, the switch operates 177 as a locking / unlocking changeover switch for the cable. This means that in one step S47, a detection of an actuation of the switch occurs. 177 The process is being monitored and, if the activation has been detected, it proceeds to step S48, and the ECU 170 the cable locking mechanism 260 This causes the cable to lock, after which the process proceeds to step S49.

[0143] In step S49, the detection of a switch activation is again considered. 177waited, and when the actuation has been detected, the process progresses to step S50, and it prompts the ECU 170 the cable locking mechanism 260 to unlock the cable, after which the process returns to step S47.

[0144] The following can be used as in Fig. As shown in Figure 15, the embodiment can also be modified in a state where, after the user has connected the charging cable to the inlet or port, 250 Once connected, the cable is locked by the first operation or activation, and the timer setting is then determined.

[0145] Fig. Figure 15 shows a flowchart to explain a third example of a process in the case where a self-locking mechanism is not set, and shows how the ECU uses the switch in different ways. As in Fig. 4, Fig. 6 and Fig. As shown in 15, the ECU determines 170 Initially, when the process is started, in step S61, it checks whether the charging cable is connected to the inlet or port. 250 is connected. The ECU 170 is able to determine whether the cable is connected based on the PISW signal or the CPLT signal.

[0146] If a cable connection is not detected in step S61, the process remains at step S61 and enters a waiting state. In step S61, the ECU proceeds 170 Then, once the cable connection has been detected, the process continues to step S62.

[0147] This means that in step S62, a detection of the switch actuation occurs. 177 The process is awaited and, if the activation has been detected, progresses to step S63, and the ECU 170 the cable locking mechanism 260This causes the cable to lock, after which the process proceeds to step S64.

[0148] In step S64, the ECU determines 170 , whether the timer's charging start time is controlled by the timer charging setting unit 176 , which in Fig. As shown in step 4, the timer has been preset. If the timer has not been set in step S64, the process proceeds to step S68, and the timer setting is deactivated, so that loading starts immediately.

[0149] On the other hand, the process continues to step S65 if the charging start time for the timer has been set in step S64. In step S65, the system waits for a predetermined period or duration for the timer to be determined or set. This predetermined duration is, for example, 10 seconds and can be adjusted as needed. This waiting period prevents charging from starting immediately after the charging cable is connected to the inlet or port. 250 has been connected so that the number of times the relay is actuated in the charging path does not need to be unnecessarily increased, thus making it possible to extend the lifespan of the relay.

[0150] In the following step, S66 is determined to determine if the switch 177within the predetermined time period during which the system waits for an actuation to set the timer in step S65, when the switch is activated. 177 If step S66 is not activated, the process proceeds to step S68, and the timer setting is deactivated, so that loading starts immediately.

[0151] If the switch is on the other side 177 If step S66 is activated within the predetermined time period, the process proceeds to step S67, and the ECU 170 The timer setting is adjusted, and the device enters a standby state without charging until the set charging start time is reached.

[0152] After the process according to step S67 or step S68, the switch operates 170as a locking / unlocking toggle switch for the cable. This means that in step S69, the detection of an actuation of the switch is triggered again. 177 The process is being monitored, and, if the activation has been detected, it proceeds to step S70, and it prompts the ECU 170 the cable locking mechanism 260 to unlock the cable, after which the process or sequence continues to step S71.

[0153] In step S71, the detection of a switch actuation is again attempted. 177 waits, and the process or sequence then progresses to step S72 once the activation has been detected, and it prompts the ECU 170 the cable locking mechanism 260 to lock the cable, after which the process returns to step S69.

[0154] To ensure the process is carried out according to Fig. 15 To apply or use in the first embodiment, step S67 can be modified into a process of deactivating the timer (immediate loading), and step S68 can be modified into a process of activating the timer.

[0155] Finally, the first and second embodiments are summarized again with reference to the drawings. The charging device for the vehicle, as described in the first or second embodiment, is configured to perform a timer-controlled charge, in which the charging device is placed in a standby state without charging until the charging start time is reached, if the charging start time has been set. The charging device for the vehicle assigns the charger 240 , which is the electrical storage device 150the vehicle charges with electrical energy supplied by a device outside the vehicle, the cable locking mechanism 260 , which locks the charging cable in a state where the charging cable is connected to the inlet or terminal 250 is connected, and the ECU 170 a device that determines whether timer charging or time-controlled charging is to be carried out, or whether immediate charging without time-controlled charging is to be carried out, whereby this is determined by assessing or determining based on the state of the switch. 177 This occurs in conjunction with the activation of the cable locking mechanism. 260 , and the charger 240 controls.

[0156] This can be done, as described in step S3 to step S6 in Fig. As shown in section 8, the ECU 170 the charger 240 control in such a way that an immediate charge is performed when the switch is turned on. 177within the predetermined time period from the moment the charging cable is connected to the inlet or port. 250 is connected or will be connected.

[0157] Additionally, as described in step S23 to step S26 in Fig. As shown in 12, the ECU 170 the charger 240 control in such a way that an immediate charge is carried out when the switch is turned on. 177 is not activated within the predetermined time period from the moment the charging cable is connected to the inlet or port. 250 is connected or will be connected.

[0158] Furthermore, as is shown in Fig. As shown in 11, the ECU 170 the switch 177 Use as a switch to clear the timer when the charging cable is not connected to the inlet or port. 250 is connected; in contrast, the ECU can 170 the switch 177as a switch for changing the locking state of the cable locking mechanism 260 Use when the charging cable is connected to the inlet or port.

[0159] Furthermore, as is shown in Fig. As shown in 13, the ECU 170 the switch 177 use as a switch to determine or set the timer when the charging cable is not connected to the inlet or port. 250 is connected; in contrast, the ECU can 170 the switch 177 as a switch for changing the locked state of the cable locking mechanism 260 Use when the charging cable is connected to the inlet or port. 250 is connected.

[0160] Furthermore, as can be seen in Fig. As shown in 15, the ECU 170 additionally the switch 177 as a switch for initiating the cable locking mechanism 260to lock the charging cable immediately after the charging cable is connected to the inlet or port. 250 is connected, use; in contrast, the ECU 170 Activate or deactivate the timer charging or time-controlled charging in the case where the switch (YES in step S66) is pressed within the predetermined time period from the time at which the cable locking mechanism 260 is in the locked state (step S63), is activated for the first time after the charging cable is connected to the inlet or port. 250 is connected.
