For convenience of description, the transverse direction of the vehicle body is taken as an X axis, the longitudinal direction of the vehicle body is taken as a Y axis, and the height direction of the vehicle body is taken as a Z axis.

As shown in fig. 1, 2, 3, and 7, the chargeable vehicle according to the present embodiment includes a vehicle body 1, and the vehicle body 1 includes a vehicle-mounted power receiving device 18. The in-vehicle power receiving device 18 includes a box 181, a charging stand 182, and an in-vehicle controller 184; the charging stand 182 and the vehicle-mounted controller 184 are disposed in the box 181; the charging dock 182 has a charging interface 1821; the vehicle-mounted controller 184 is used for being in communication connection with the charging controller 64 of the charging pile 6; the vehicle-mounted controller 184 is configured to acquire a plug-in state of the vehicle-mounted power receiving device 18 and the plug-in device 63 when receiving the charging start instruction, and start the charging mode for charging when the plug-in state is a normal plug-in state. The charging controller 64 is configured to control the servo sliding table 62 to move according to the position of the vehicle-mounted power receiving device 18 when receiving a charging instruction, so that the charging plug 631 is plugged into the charging interface 1821 of the vehicle-mounted power receiving device 18. The vehicle-mounted power receiving device 18 needs to be matched with the charging pile 6 to complete charging of the rechargeable vehicle.

For ease of understanding, the structure of the chargeable vehicle will be described in conjunction with the structure of the charging pile 6 shown in fig. 6.

The charging pile 6 is usually installed at a vehicle station, a bus station or other places where it is convenient to charge the vehicle. Exemplarily, a plurality of parking spaces are arranged at the charging place, and the charging piles 6 are arranged beside the parking spaces. The vehicle drives into the charging field and stops in the parking space and is charged through the charging pile 6. The charging pile 6 can be arranged on the ground; or, the hanging device is hung on the wall surface such as the side wall; alternatively, the charging device may be suspended from a ceiling or the like installed above the charging field. The in-vehicle power receiving device 18 may be provided at the bottom, side, or top of the vehicle.

For example: when the charging pile 6 is disposed on the ceiling, the vehicle-mounted power receiving device 18 is disposed on the roof, and the charging interface 1821 faces upward, the vehicle-mounted controller 184 may control the servo sliding table 62 to drive the charging plug 631 to move along the horizontal direction to be vertically aligned with the charging interface 1821 according to the position information of the vehicle-mounted power receiving device 18, and then control the servo sliding table 62 to drive the charging plug 631 to move vertically downward to be plugged into the charging interface 1821.

When the charging pile 6 is disposed on the ceiling, the vehicle-mounted power receiving device 18 is disposed on the side or the bottom of the vehicle, and the charging interface 1821 faces the side, the vehicle-mounted controller 184 may control the servo sliding table 62 to vertically move and drop the charging plug 631 to the same height as the charging interface 1821 according to the position information of the vehicle-mounted power receiving device 18, then horizontally move to align with the charging interface 1821, and then control the servo sliding table 62 to horizontally move and plug the charging plug 631 into the charging interface 1821.

When the charging pile 6 is disposed on the ceiling, the vehicle-mounted power receiving device 18 is disposed on the side or bottom of the vehicle, and the charging interface 1821 faces downward, the vehicle-mounted controller 184 controls the servo sliding table 62 to vertically move with the charging plug 631 according to the position information of the vehicle-mounted power receiving device 18 and fall to be lower than the charging interface 1821, then horizontally move to be aligned with the charging interface 1821, and then control the servo sliding table 62 to upwards move with the charging plug 631 to be plugged into the charging interface 1821.

When the charging pile 6 is arranged on the ground, the vehicle-mounted power receiving device 18 is arranged on the roof and the charging interface 1821 faces upward, the vehicle-mounted controller 184 can control the servo sliding table 62 to drive the charging plug 631 to vertically move upwards to be higher than the charging interface 1821 according to the position information of the vehicle-mounted power receiving device 18, then move to be vertically aligned with the charging interface 1821 along the horizontal direction, and then control the servo sliding table 62 to drive the charging plug 631 to vertically move downwards to be connected with the charging interface 1821 in an inserting mode.

When the charging pile 6 is disposed on the ground, the vehicle-mounted power receiving device 18 is disposed on the roof, the side or the bottom, and the charging interface 1821 faces the side, the vehicle-mounted controller 184 can control the servo sliding table 62 to drive the charging plug 631 to vertically move and horizontally move to be aligned with the charging interface 1821 according to the position information of the vehicle-mounted power receiving device 18, and then control the servo sliding table 62 to drive the charging plug 631 to horizontally move to be plugged with the charging interface 1821.

When the charging pile 6 is arranged on the ground, the vehicle-mounted power receiving device 18 is arranged on the side or the bottom of the vehicle, and the charging interface 1821 faces downward, the vehicle-mounted controller 184 can control the servo sliding table 62 to vertically move and fall to be lower than the charging interface 1821 with the charging plug 631 according to the position information of the vehicle-mounted power receiving device 18, then horizontally move to be aligned with the charging interface 1821, and then control the servo sliding table 62 to upwards move with the charging plug 631 to be plugged with the charging interface 1821.

For convenience of description, the charging pile 6 is installed on the ground, the vehicle-mounted power receiving device 18 is installed on the roof, and the charging interface 1821 faces the side. As shown in fig. 4 and 5.

The support body 61 has a certain height. The upper portion of the support main body 61 is provided with a servo slide table 62. The servo slide table 62 is slidably provided to the support main body 61. The plugging device 63 is disposed on the servo sliding table 62. The plug-in device 63 has a charging plug 631 and a pose compensation mechanism. The charging controller 64 is mounted to the support main body 61. The charge controller 64 is communicatively connected to the servo sled 62. In addition, the charging pile 6 can also be provided with a voltage conversion device, a circuit protection device and the like.

The servo sliding table 62 can drive the plug device 63 to move toward the vehicle-mounted power receiving device 18 of the vehicle under the control instruction of the charging controller 64 until the charging plug 631 is plugged in place with the charging interface 1821 of the vehicle-mounted power receiving device 18, so as to charge the vehicle. The servo slide table 62 can also drive the plug device 63 to move away from the vehicle-mounted power receiving device 18 of the vehicle under the control instruction of the charging controller 64.

The servo slide 62 may be a multi-axis driving mechanism, so that the servo slide 62 has a position adjusting function for the charging plug 631 within a certain distance range. When the vehicle is required to be charged, the parking position of the vehicle needs to make the vehicle-mounted power receiving device 18 within the adjustment range of the servo sliding table 62; generally, the longitudinal adjustment range of the vehicle-mounted power receiving device 18 and the plug device 63 is within ± 25cm, and the lateral adjustment distance of the vehicle-mounted power receiving device 18 and the plug device 63 is within ± 25 cm.

Because the actual load of the vehicle, the tire pressure, and the like cause the deviation between the actual height and the preset height of the charging interface 1821, the posture compensation mechanism 632 is adopted to drive the charging plug 631 to float along multiple directions, so as to adapt to the actual position of the charging interface 1821. The pose compensation mechanism is particularly useful for floatingly connecting the charging plug 631 to the charging interface 1821 of the charging dock 182, and preventing the charging plug 631 and/or the charging dock 182 from being damaged due to hard contact between the charging plug 631 and the charging dock 182.

For example: the servo sliding table 62 may be a three-axis servo sliding table 62, which can move along the X-axis, Y-axis, and Z-axis directions relative to the vehicle-mounted power receiving device 18, that is, the servo sliding table 62 can drive the plugging device 63 to move along the X-axis direction, Y-axis direction, and Z-axis direction, so as to adjust the position of the plugging device 63. The posture compensation mechanism 632 can provide six-degree-of-freedom floating amount for the charging plug 631, and prevent the charging plug 631 from being rigidly connected to the charging dock 182 and damaged, that is, the posture compensation mechanism 632 can provide front and rear floating amount along the X-axis direction, left and right floating amount along the Y-axis direction, and up and down floating amount along the Z-axis direction for the charging plug 631, so that the charging plug 631 can be conveniently inserted into the charging interface 1821 of the charging dock 182. Thus, there is a deviation in the parking position of the vehicle, the position of the charging plug 631 can be quickly adjusted through the servo sliding table 62, and then the position of the charging plug 631 can be finely adjusted through the posture compensation mechanism 632, so as to ensure that the charging plug 631 can be quickly aligned with the charging interface 1821.

In other examples, the servo slide 62 may be a translation mechanism, that is, the servo slide 62 moves the charging plug 631 toward or away from the on-board powered device 18. The pose compensation mechanism 632 is a multi-axis motion mechanism, which has multiple degrees of freedom movement, and is beneficial to ensure that the plug-in device 63 is aligned with the vehicle-mounted powered device 18, and the charging plug 631 is smoothly inserted into the charging interface 1821 of the charging dock 182, thereby preventing the charging plug 631 and the charging dock 182 from being damaged due to hard contact.

The in-vehicle power receiving device 18 is provided at the top of the vehicle, and is located near one side edge of the vehicle. The in-vehicle power receiving device 18 includes: a box body 181, a charging seat 182 and a vehicle-mounted controller 184 arranged in the box body 181. The charging dock 182 is disposed at the side, front, rear, or top of the vehicle, and the charging dock 182 has a charging interface 1821. The charging interface 1821 is provided toward the side of the vehicle. The charging dock 182 may also be electrically connected to an energy storage device disposed on the vehicle. The energy storage device may be provided on the top or bottom of the vehicle. The energy storage device can be a super capacitor, a storage battery and the like. The vehicle-mounted controller 184 is electrically connected to each of the related devices, and is configured to control the charging process at an early stage and a later stage.

In specific implementation, the charging controller 64 is configured to control the servo sliding table 62 to move according to the position of the vehicle-mounted power receiving device 18 when receiving a charging instruction, so that the charging plug 631 is plugged into the charging interface 1821 of the vehicle-mounted power receiving device 18. The vehicle-mounted controller 184 is configured to acquire a plug-in state of the vehicle-mounted power receiving device 18 and the plug-in device 63 when receiving the charging start instruction, and start the charging mode for charging when the plug-in state is a normal plug-in state.

The charging command may be issued by the charging pile 6, for example: be equipped with the button that charges on charging pile 6, operating personnel presses the button that charges, produces the instruction of charging. Alternatively, the charging command may be issued to the vehicle, for example: the vehicle is provided with a charging button, and an operator presses the charging button on the vehicle to generate a charging instruction.

Communication connection is established in advance between the charging controller 64 of the charging pile 6 and the vehicle-mounted controller 184 of the vehicle-mounted powered device 18, so that interaction of data such as a charging instruction is facilitated. Specifically, the charging controller 64 of the electric pile and the vehicle-mounted controller 184 of the vehicle-mounted powered device 18 may communicate through a wireless network; for example: the communication can be performed through a wireless communication network provided by an operator, through a hotspot, or through a local area network provided by a charging field. During specific implementation, when the charging pile 6 identifies that the vehicle arrives at a charging site, wireless network connection is established with the vehicle. For example, the charging pile 6 may detect a beacon provided on the vehicle, and when the beacon is detected, it indicates that the vehicle enters the charging site.

Illustratively, the charge controller 64 is specifically configured to: acquiring hot spot information of a vehicle; sending a hotspot connection request to the vehicle-mounted controller 184 according to the hotspot information; the onboard controller 184 is also configured to: upon receiving a hotspot connection request sent by the charging controller 64, a wireless network connection is established with the charging controller 64.

After the charging controller 64 establishes the wireless connection with the onboard controller 184, in some examples, the onboard controller 184 is specifically configured to: receiving a charging starting instruction generated when a charging button on a vehicle is triggered; a charging instruction is sent to the charging controller 64 via a wireless network. The onboard controller 184 is also configured to send a charge stop command to the charge controller 64 via the wireless network upon acquisition that a stop charge button on the vehicle is triggered. In other examples, the charging controller 64 may be configured to send a charging initiation command to the onboard controller 184 via the wireless network, the charging initiation command being generated when a charging button on the charging post 6 is triggered. The charging controller 64 can be used to send a charging stop command generated when a charging stop button on the charging pile 6 is triggered to the vehicle-mounted controller 184 through the wireless network

When the charging controller 64 receives the charging instruction, the position information of the in-vehicle power receiving device 18 is acquired, and for example, the position information of the in-vehicle power receiving device 18 is determined after the vehicle image is captured by the image capturing device and the image processing is performed. Alternatively, the charging controller 64 may determine the position information of the in-vehicle power receiving device 18 by a sensor, an inductive mark, and the like provided in the charging pile 6 and the vehicle, respectively.

When the vehicle-mounted power receiving device 18 is determined to be located within the preset adjusting range according to the position information of the vehicle-mounted power receiving device 18, the charging controller 64 controls the servo sliding table 62 and/or the pose compensation mechanism 632 to move until it is determined that the charging plug 631 faces the charging interface 1821 according to the position information of the vehicle-mounted power receiving device 18, and the charging controller 64 can control the servo sliding table 62 to drive the charging plug 631 to be plugged into the charging interface 1821. After the charging plug 631 is plugged into the charging interface 1821, the charging pile 6 can charge the energy storage device on the vehicle through the charging dock 182.

After the charging controller 64 controls the servo sliding table 62 to drive the charging plug 631 to be plugged into the charging interface 1821 of the vehicle-mounted power receiving device 18, the vehicle-mounted controller 184 detects the plugging state. For example, detection devices such as a proximity switch and a travel switch can be arranged to detect the plugging state, and when the plugging is in place and the contact is good, the detection devices can send corresponding signals. When the vehicle-mounted controller 184 determines that the plugging state is normal plugging, the charging mode is started, and the energy storage device on the vehicle is charged through the charging pile 6.

The embodiment of the application provides a chargeable vehicle, through on-vehicle power device 18 with corresponding 6 cooperations of electric pile that fill, realized automatic charging the vehicle, need not manual operation, improved the intellectuality and the charging efficiency of charging process.

Specifically, the support frame 6321 is a main bearing member of the pose compensation mechanism 632. For example, the supporting frame 6321 may include two symmetrically disposed right-angled triangular arms, a space is formed between the two right-angled triangular arms for the charging plug 631 and the circuit connected to the charging plug 631 to pass through, a right-angled surface of each right-angled triangular arm is fixedly connected to the servo sliding table 62, and another right-angled surface is used for fixing the components of the posture compensation mechanism 632.

A first mounting plate 6322, a second mounting plate 6323 and a third mounting plate 6324 are sequentially arranged between the support frame 6321 and the charging plug 631 at intervals. That is, the first mounting plate 6322 is disposed near the support bracket 6321, the third mounting plate 6324 is used to fix the charging plug 631, and the second mounting plate 6323 is disposed between the first mounting plate 6322 and the second mounting plate 6323. The first mounting plate 6322 and the second mounting plate 6323 are provided with through holes for the charging plug 631 to pass through, and the through holes are in clearance fit with the charging plug 631 to provide a certain supplementary space for the charging plug 631.

In particular implementations, the pose compensation mechanism 632 may be a floating mechanism. The transverse compensation assembly, the vertical compensation assembly and the longitudinal compensation assembly can be realized by adopting a floating structure.

In one possible implementation, the plug device 63 further includes at least one guide 634, and accordingly, the charging seat 182 is provided with at least one guide hole matching with the guide 634. The guide 634 is adapted to the number of guide holes. When the guide 634 has a plurality, for example, when the guide 634 is 2, 3, or 4, the plurality of guides 634 are spaced apart along the circumferential direction of the charging plug 631. The guide 634 may be embodied as a guide pin; accordingly, the guide holes 1822 are pin holes.

For example: the charging stand 182 is symmetrically provided with two guide holes, and the two guide holes are respectively positioned at the left side and the right side of the charging interface 1821 of the charging stand 182; accordingly, the third mounting plate 6324 is provided with two guides 634, the two guides 634 being symmetrically disposed on the left and right sides of the charging plug 631; when the charging plug 631 is plugged into the charging interface 1821, the guiding element 634 can be plugged into the guiding hole to guide the plugging device 63 to be connected with the charging stand 182, so that the charging plug 631 is plugged into the charging interface 1821 smoothly.

In this example, the insertion of the charging plug 631 into the charging interface 1821 of the vehicle-mounted power receiving device 18 in the preset direction can be guided by the fitting of the guide 634 with the guide hole.

In order to ensure the reliability of the electrical connection between the plug device 63 and the charging dock 182, the charging plug 631 can be locked after being inserted into the charging interface 1821, so as to prevent the charging plug 631 from being separated from the charging interface 1821. In one possible implementation, the plug device 63 and the charging seat 182 are further provided with locking members. The locking member is used for locking the plug device 63 and the vehicle-mounted power receiving device 18 when the charging plug 631 is plugged in place with the charging interface 1821. Illustratively, the locking member includes at least one electromagnetic lock. In some examples, an electromagnetic lock may be provided to the plug device 63. In other examples, an electromagnetic lock may be provided to the charging dock 182.

Take the electromagnetic lock disposed in the plug device 63 as an example: when the electromagnetic locks 634 are plural, the plural electromagnetic locks 634 are spaced apart along the circumference of the charging plug 631. The electromagnetic lock 634 of the charging post 6 is disposed on a side of the third mounting plate 6324 facing the charging stand 182. Specifically, the electromagnetic lock 634 of the charging pile 6 is powered on to generate magnetic force, and based on the magnetic induction effect, the electromagnetic lock 634 of the charging pile 6 and the matching part of the charging stand 182 generate attraction force, so that the plug device 63 and the vehicle-mounted power receiving device 18 are locked.

In one possible implementation manner, the plug device 63 further includes a positioning sensor 636, and the charging stand 182 is provided with a positioning identifier; the positioning sensor 636 is used for detecting a positioning identifier provided to the vehicle-mounted power receiving device 18; the charging controller 64 is configured to determine, according to a detection result of the positioning sensor 636, that the charging plug 631 is aligned with the charging interface 1821 of the vehicle-mounted powered device 18, and control the pose compensation mechanism servo sliding table 62 to drive the charging plug 631 to be plugged into the charging interface 1821.

In a specific implementation, the positioning sensor 636 may be a photoelectric sensor, an infrared sensor, a laser sensor, or the like. The positioning mark may be a mark member that can be recognized by the positioning sensor 636, and may be specifically set according to the sensor used.

For example: when the charging plug 631 has a longitudinal deviation from the charging interface 1821, the charging controller 64 may control the servo sliding table 62 to drive the plug device 63 to move in the longitudinal direction (Y-axis direction). During the movement, the positioning sensor 636 transmits the detection result to the charge controller 64 in real time. When the charging controller 64 determines that the plug device 63 is aligned with the charging dock 182 along the longitudinal direction according to the signal detected by the positioning sensor 636, the translational driving device is controlled to move towards the charging dock 182 along the transverse direction (the X-axis direction) so as to plug the plug device 63 into the charging interface 1821.

When the height of the plug is different from that of the charging interface 1821, that is, when the charging plug 631 has a vertical deviation from the charging interface 1821, the charging controller 64 may control the servo sliding table 62 to drive the plug device 63 to move in the vertical direction (Z-axis direction). During the movement, the positioning sensor 636 transmits the detection result to the charge controller 64 in real time. When the charging controller 64 determines that the plugging device 63 is aligned with the charging dock 182 along the vertical direction according to the signal detected by the positioning sensor 636, the translational driving device is controlled to move towards the charging dock 182 along the direction perpendicular to the horizontal direction (the X-axis direction) so as to plug the plugging device 63 into the charging interface 1821.

In one possible implementation manner, as shown in fig. 8 and 9, the charging pile 6 further includes a housing and a charging protection cover 65; the servo sliding table 62 and the plugging device 63 are positioned in a space enclosed by the shell; the charging protection cover 65 is slidably provided above the housing; charge protection cover 65 is configured to slide toward vehicle-mounted power receiving device 18 to a covering position where charge plug 631 and charge interface 1821 are covered when charge plug 631 is plugged into charge interface 1821; charge shield 65 is configured to slide away from vehicle-mounted power receiving device 18 to an initial position when charge plug 631 is disengaged from charge interface 1821.

For external environment such as the rainwater of avoiding the charging process harm such as the erosion of on-vehicle charging system, this embodiment fills electric pile 6 and still is equipped with casing and charging protection cover 65. The shell is used for protecting the servo sliding table 62 and the plug-in device 63, and the plug-in device 63 and the servo sliding table 62 are positioned in the shell; it is understood that the plug device 63 can be extended out of the housing and connected to the charging base 182 of the vehicle-mounted power receiving device 18.

Since the plug-in unit 63 is required to extend out of the housing during charging, and since protection is required for the charging unit in use, the charging protection cover 65 can be provided at the upper part of the housing and can slide relative to the housing; when the plug device 63 extends out of the housing, the charging protection cover 65 can slide from the initial position to one side of the vehicle along the upper part of the housing, and the charging protection cover 65 is covered above the vehicle-mounted power receiving device 18, that is, the charging protection cover 65 can form a protection space above the transverse distance between the vehicle and the charging pile 6, so as to provide protection for the plug device 63 and the connection position of the plug device 63 and the charging stand 182, and improve the reliability and safety in the charging process. At this time, the position of the charging protection cover 65 may be a cover position. The initial position of the charging protection cover 65 can be set according to actual needs.

In order to further improve the degree of automation of the charging operation, the charging controller 64 may control the charging protection cover 65 to switch between the initial position and the cover position. Specifically, the method comprises the following steps: the charge controller 64 is also configured to: before the charging plug 631 is plugged into the charging interface 1821, the charging protection cover 65 is controlled to move to the covering position; after charging plug 631 is disengaged from charging interface 1821, charging protection cover 65 is controlled to move to the initial position. Correspondingly, a protective cover driving mechanism is further provided, and the protective cover driving mechanism is electrically connected with the charging controller 64 and is in driving connection with the charging protective cover 65. In particular, the protective cover driving mechanism can adopt an electric, hydraulic or pneumatic driving structure. The charge protection cover 65 may take a variety of forms, such as: the folding shed is of a telescopic structure, and a fixed cover plate structure can also be adopted.

Of course, in other examples, the charging protection cover 65 may also be disposed at the vehicle-mounted power receiving device 18, and the implementation process at this time may be similar to that described above, and will not be described herein again.

In this example, a charging protection cover 65 is used to protect the plug device 63 and the in-vehicle power receiving device 18 during the plugging process and/or during the charging process. Before the plug device 63 of the charging pile 6 is controlled to be plugged with the vehicle-mounted power receiving device 18, the charging protection cover 65 is controlled to move to cover between the plug device 63 and the vehicle-mounted power receiving device 18, and water drops can be prevented from entering the plug device 63 and the vehicle-mounted power receiving device 18 in rainy and snowy weather.

In one possible implementation, the charging cradle 182 further includes: the protection plate 183, the protection plate 183 is rotatably connected with the box body 181; when the protection plate 183 is in a closed state, the protection plate 183 is hermetically connected with the box body 181 so as to protect the charging seat 182 and other parts in the box body 181; when the protection plate 183 is in the open state, the charging seat 182 is exposed from the opening of the box 181.

To further enhance the automation of the charging operation, the guard 183 may be controlled by the charging controller 64 to switch between the open position and the closed position. Specifically, the method comprises the following steps: the onboard controller 184 is also configured to: when a charging start instruction is received, the protection plate 183 is controlled to move to an open state; when the charging is completed, the control guard 183 moves to the off state.

In a specific implementation, the upper end of the protection plate 183 is hinged to the box body 181 through a hinge shaft; the electric protection driving mechanism can be electrically connected with the vehicle-mounted controller 184, the electric protection driving mechanism can also be in driving connection with the hinge shaft, and the electric protection driving mechanism can control the electric protection driving mechanism to drive the hinge shaft to rotate according to a control instruction of the vehicle-mounted controller 184 so as to control the protection plate 183 to be switched between the closed position and the open position. In other examples, the driving mode can be realized by adopting pneumatic and hydraulic driving.

In addition, the guard plate 183 is connected to the movable apron plate 104, and when the electric guard driving mechanism determines that the guard plate 183 rotates, the movable apron plate 104 rotates together with the guard plate 183; the profile of the movable skirt 104 can be adapted to the body skirt 103 near the vehicle-mounted power receiving device 18, so that when the electric shield driving mechanism driving guard 183 rotates to the closed position, the movable skirt 104 can be engaged with the body skirt 103 outside the vehicle body 1, which is beneficial to improving the integrity of the vehicle body 1. For example, the movable skirt board 103 may be an arc-shaped plate, and the specific arc thereof needs to be set according to the vehicle body skirt board 103 near the vehicle-mounted power receiving device 18; the movable skirt board 103 can be directly connected with the protection plate 183 or connected with the protection plate 183 through other connecting structures, and can be specifically arranged according to actual requirements.

In one possible implementation, the charging controller 64 is further configured to: acquiring the electric quantity of a vehicle powered device; when the electric quantity reaches a preset upper limit value, the plug device 63 is controlled to be separated from the vehicle-mounted powered device 18 and moved to return.

During the charging process, the charging controller 64 obtains the power of the vehicle powered device, and when it is determined that the power reaches a preset upper limit value, controls the plug device 63 to separate from the vehicle powered device 18 and move to the position. The electric quantity can be detected by an electric quantity sensor arranged on the vehicle, a processor arranged on the vehicle analyzes and judges the electric quantity, when the electric quantity is judged to reach a preset upper limit value, the electric quantity is full charged, electric quantity full charge information is sent to the charging controller 64 of the charging pile 6 through a wireless network, and the charging controller 64 controls the plug-in device 63 to be separated from the vehicle-mounted powered device 18 and moves to the position. Or, the vehicle sends the electric quantity detected by the sensor to the charging controller 64 of the charging pile 6, the charging controller 64 of the charging pile 6 analyzes and judges the electric quantity, and when the electric quantity is judged to reach the preset upper limit value, the electric quantity indicates that the electric quantity is fully charged, and the charging controller 64 controls the plug-in device 63 to be separated from the vehicle-mounted power receiving device 18 and moves to return.

In one possible implementation, the charging controller 64 is further configured to: when receiving the charging stop instruction, the control plug device 63 is separated from the in-vehicle power receiving device 18 and moved back.

During charging, when the charging controller 64 receives a charging stop instruction, the plug device 63 is controlled to be separated from the in-vehicle power receiving device 18 and moved back. The charging stop instruction may be generated when a charging stop button provided on the charging pile 6 is pressed; alternatively, the charge stop instruction may be generated when a stop charge button provided on the vehicle is pressed and transmitted to the charge controller 64 via the wireless network. The charging controller 64 controls the plug device 63 to separate from the vehicle-mounted power receiving device 18, and moves to return to store in a preset position of the charging pile 6.

In one possible implementation, in the event of a charging failure, the control plug device 63 is detached from the vehicle-mounted power receiving device 18 and plugged again.

After the plug device 63 is plugged into the charging interface 1821, if charging cannot be started or the vehicle side does not receive charging current, or power is suddenly cut off during charging, a charging failure occurs. When the charging pile 6 acquires that the above problem occurs, the plug device 63 is controlled to be separated from the vehicle-mounted power receiving device 18, and the plugging is performed again in any one of the above manners. Or, a software restart mode can be executed to perform power-off processing on the related circuit or controller and power-on again.

Furthermore, the charging controller 64 may be further configured to lock the electric drive system of the vehicle before charging the in-vehicle powered device 18, and enter the charging mode to start charging when detecting that the electric drive system has locked the feedback information, so as to improve the safety of the charging process.

In one possible implementation, the onboard controller 184 is further configured to: before the charging mode is started for charging, the electric drive system of the vehicle is controlled to be locked, so that the vehicle cannot start running. And after the locking is finished, the charging is started, so that the safety of the charging process is improved.

In one possible implementation, the onboard controller 184 is further configured to: acquiring electric quantity in the charging process; when the electric quantity reaches the preset upper limit value, a charging completion instruction is sent to the charging controller 64, so that the charging controller 64 controls the plug device 63 to be separated from the charging interface 1821 and move to return.

In one possible implementation, the onboard controller 184 is further configured to: acquiring electric quantity in the running process of a vehicle; and generating charging reminding information when the electric quantity is lower than a preset lower limit value. The charging reminding information can prompt the driver that the electric quantity is insufficient and the charging is needed through modes such as audio, indicator lights, pictures and the like.

On the basis of the scheme, the vehicle-mounted controller 184 performs data interaction with a battery management system in the energy storage device. For example: the battery management system detects the remaining power in the energy storage device and sends it to the onboard controller 184 for monitoring.

During the charging process, when the remaining capacity reaches the preset upper limit value, the vehicle-mounted controller 184 sends charging completion indication information to the charging controller 64. The remaining capacity state of each group of supercapacitors is represented by four bar graphs on the display main interface of the cockpit, different sections are displayed in green, yellow and red, and specific remaining capacity values are displayed, for example: 50% -100% are displayed as green, 20% -50% are displayed as yellow, and 0% -20% are displayed as red.

In the running process of the vehicle, when the residual electric quantity is lower than the preset lower limit, charging reminding information is sent out, an alarm reminding picture can be generated through a display screen of the vehicle, and an alarm reminding sound can be sent out through a buzzer. The preset lower limit may be, for example, 20% of the capacity of the energy storage device.

When the remaining capacity is lower than a first lower limit value (e.g., 30%) during the operation of the vehicle, the on-board controller 184 is configured to reduce the power of the air conditioner of the vehicle; and when the residual capacity is lower than a second lower limit value (for example, 10%), controlling the vehicle air conditioner to switch to the ventilation mode so as to reduce the electric energy consumption. The second lower limit value is lower than the first lower limit value.

In the running process of the vehicle, when the residual electric quantity reaches 5%, an emergency cruising button is popped up on a display screen of a vehicle cockpit, and an emergency cruising mode is clicked to enter, so that the emergency motor car with low electric quantity is realized. Under normal conditions, the button is invisible, when the average residual capacity of four groups of super capacitors in the energy storage device reaches 5%, an emergency endurance button is popped up, and if a driver presses the button, the four groups of capacitors enter an emergency endurance state and display the residual energy in percentage form.

The vehicle sets up emergent start function, and at the condition of energy storage device feed, through pressing emergent start button to under the national standard socket insertion condition that charges, main loop contactor is not closed, only closes the loop contactor of plug-in device 63. If the voltage value of the low-voltage input end of the vehicle is lower than 18V and no high voltage exists, the charger outputs 500V to supply high voltage to the auxiliary converter to realize emergency starting. After the auxiliary converter is put into operation, the charger outputs DC24V power in a modular mode, and the vehicle wakes up.
