Detailed Description
Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the invention and are not to be construed as limiting the invention.
A station charging system and method of a vehicle according to an embodiment of the present invention will be described with reference to the drawings.
Fig. 2 is a schematic structural diagram of a station charging system of a vehicle according to an embodiment of the present invention. As shown in fig. 2, the station charging system 100 of the vehicle includes: an actuator 10, a charging mechanism 20, and a controller 30.
Wherein, the actuating mechanism 10 is arranged at the charging station, and the actuating mechanism 10 is used for detaching the power battery of the vehicle parked at the preset position of the charging station and placing the power battery in the battery charging area of the charging station. The charging mechanism 20 is provided at a charging station, and the charging mechanism 20 is used for charging the power battery placed in the battery charging area. The controller 30 is respectively communicated with the actuator 10 and the vehicle, the controller 30 is used for receiving the state of charge SOC of the power battery sent by the vehicle, controlling the vehicle to stop at a preset position when the SOC of the power battery is smaller than a preset threshold value, and controlling the actuator 10 to remove the power battery of the vehicle and place the power battery in a battery charging area, so that the charging mechanism 20 charges the power battery placed in the battery charging area.
Alternatively, the controller 30 may communicate with the vehicle in real time through a wireless access point to receive the SOC of the power battery transmitted by the vehicle, and the controller 30 may communicate with the actuator 10 wirelessly to transmit control information to the actuator 10 to control the actuator 10.
It should be noted that the kinetic energy source of the vehicle may be a power battery mounted on the vehicle, and the vehicle may be a rail vehicle, such as a tram, which is generally parked at a specific station during operation, and a specific charging station is required to be set up for charging the vehicle in order to ensure sufficient kinetic energy. Alternatively, each specific station at which the vehicle stops may be provided with a charging station.
In this embodiment, the preset threshold may be calibrated according to the actual needs of the vehicle, and the preset threshold may also be a constant or a variable. For example, when the preset threshold is a variable, after the driving route of the vehicle is determined, the preset threshold is positively correlated with the driving distance corresponding to the to-be-driven route or the number of remaining stations, that is, the shorter the driving distance corresponding to the to-be-driven route is, or the smaller the number of remaining stations is, the smaller the preset threshold is. It should be understood that the value of the preset threshold should be greater than the SOC corresponding to the discharge prohibition voltage of the power battery, and the preset threshold should be set to ensure that the vehicle travels to the charging station.
Specifically, as shown in fig. 3, during the running of the vehicle on the track (e.g., running rails), real-time wireless communication may be performed with the controller 30 to transmit the SOC of the power battery of the vehicle to the controller 30. After acquiring the SOC of the power battery, the controller 30 determines whether the SOC value is smaller than a preset threshold, and if so, controls the vehicle to stop at a preset position of the charging station. After the vehicle stops at the preset position, the actuator 10 is controlled to remove the power battery of the vehicle and place the power battery in the battery charging area. After the power battery is placed in the battery charging area, the charging mechanism 20 can charge the power battery placed in the battery charging area, wherein the charging mechanism 20 can be powered by a power grid (e.g., 220V utility grid). Therefore, compared with the technology shown in fig. 1, the charging system does not need to lay a charging rail, erect a contact network and the like on the charging station, the danger coefficient of the charging station is reduced, and in addition, a charging device does not need to be arranged on the vehicle, so that the information interaction between the vehicle and a charging mechanism is reduced, and the cost of the vehicle is reduced.
Further, after the power battery is charged, the controller 30 also controls the actuator 10 to take out the power battery from the battery charging area and mount the power battery on the vehicle. When the voltage of the power battery reaches the charging prohibition voltage or the SOC reaches a set value such as 100%, the completion of charging of the power battery can be judged.
Specifically, after the power battery is detached from the vehicle and placed in the battery charging area for charging, the vehicle is in a waiting state until the power battery is completely charged, and the controller 30 controls the actuator 10 to take out the power battery from the battery charging area and install the power battery on the vehicle, so that the vehicle can continue to run.
In one embodiment of the invention, the charging station is further provided with a battery storage area, and the battery storage area stores at least one power battery which is charged completely. Alternatively, the battery storage area may be a battery charging area, for example, the battery charging area may be pre-loaded with a power battery, and the power battery may be fully charged (i.e. the charging is completed) or not fully charged, and if not fully charged, the power battery placed in the battery charging area should be in a full state when the vehicle to be charged arrives at the charging station.
Further, when the vehicle to be charged is about to enter the charging station, the controller 30 further controls the actuator 10 to take a power battery whose charging is completed from the battery storage area, and controls the actuator 10 to mount the power battery whose charging is completed on the vehicle after the actuator 10 removes the power battery of the vehicle. Therefore, the power battery is quickly replaced, the stop time of the vehicle at a station is reduced, and the running continuity of the vehicle is ensured.

In this embodiment, the controller 30 is configured to control the first manipulator 11 to remove the power battery of the vehicle and place the power battery at the first end a of the transfer mechanism 12 after the vehicle stops at the preset position, further control the transfer mechanism 12 to transfer the power battery from the first end a to the second end B, and control the second manipulator 13 to place the power battery in the battery charging area after the power battery is transferred to the second end B.
In another embodiment of the present invention, as shown in fig. 5, the actuator 10 includes a movable third robot 14. Alternatively, the third robot 14 may be provided with a pulley at the bottom and an arm structure at the upper part, wherein when the third robot 14 is controlled to move, the pulley may be directly driven to rotate until the third robot 14 moves to a destination.

Specifically, the control unit 22 is configured to obtain a charging parameter of the power battery when the power battery is placed in the battery charging area, and adjust the output voltage on the dc side of the charger 21 according to the charging parameter, where the charging parameter at least includes the voltage of the power battery. Further, when the output voltage on the dc side of the charger 21 is greater than the voltage of the power battery and the difference between the output voltage and the voltage of the power battery is within the preset range, the control unit 22 controls the first switch S1 to close, and at this time, the control unit 22 may control the charger 21 to charge the power battery in a voltage-stabilizing current-limiting manner. The preset range can be calibrated according to factory parameters of the power battery. It should be understood that the charger 21 can charge different types of power batteries.
Optionally, the charging parameters of the power battery may further include the number of nuclear charges SOC and/or the maximum allowable charging power of the power battery, so that the control unit 22 adjusts the charging manner of the charger 21 according to the maximum allowable charging power of the power battery, and the controller 30 determines whether the charging is completed according to the SOC or the voltage of the power battery.
Further, the control unit 22 is also used for reducing the charging power of the charger 21 to 0 when the power battery is completely charged, and controlling the first switch S1 to be turned off so as to avoid the power battery from being overcharged.
Further, as shown in fig. 5, the charging mechanism 20 further includes a second switch S2, the second switch S2 is connected between the ac side of the charger 21 and the power grid, wherein the control unit 22 is further configured to control the second switch S2 to be closed when the output voltage of the dc side of the charger 21 is adjusted according to the charging parameters, and to control the second switch S2 to be opened after the first switch S1 is opened after the power battery is charged. Thereby, the safety of the charging mechanism 20 can be ensured.
