    [030]. Detailed description of the achievements [031]. The embodiments of the present invention will be described in detail below in conjunction with the drawings of
    Petition 870160077050, of 12/19/2016, p. 18/46
    10/24 monitoring. Naturally, the embodiments described here are merely designed for description and explanation, rather than limiting the present invention.
    [032]. Figure 1 is a flow chart of the loading control method provided in accordance with an embodiment of the present invention, in which the loading control method can be applied to a pistol-shaped loading coupler. As shown in figure 1, the loading control method can include the following steps.
    [033]. In step S11, a pressure state of a pistol-shaped loading coupler latch button is detected.
    [034]. Specifically, the pressure state of the latch button can be determined, for example, through parameters such as the magnitude, duration, frequency and times of applying pressure to the latch button. Latch button pressure is a force exerted on the latch button by a user mutually pressing the latch button. The pressure duration is the duration when the user presses the latch button. Pressure frequency is the number of times the pressure is applied in a unit time.
    [035]. Figure 2 is a schematic diagram of a pistol-shaped loading coupler provided in accordance with an embodiment of the present invention. As shown in figure 2, an action detection device 10 can be arranged on the pistol-shaped loading coupler latch button 20. As an example, action detection device 10 can be a pressure sensor or a pressure switch. In this case, the pistol-shaped loading coupler 20 can detect the pressure on the pistol-shaped loading coupler latch button and the duration of pressure there by means of the action detection device 10. [036]. Now regarding figure 1, in step S12, a
    Petition 870160077050, of 12/19/2016, p. 19/46
    11/24 control is sent to a load cell connected to the pistol-shaped load coupler according to a detection result, in which the control signal is used to allow the load cell to obtain a load control strategy and loading stack control to perform an operation corresponding to a loading control strategy.
    [037]. In the present invention, the operation of determining a loading control strategy can be carried out on the side of the pistol-shaped loading coupler or on the side of the loading stack. In the case of carrying out the operation on the side of the charge stack, step S12 may include: sending a control signal including the detection result to the charge stack connected to the pistol-shaped charging coupler, the control signal being is used to allow the load cell to obtain a load control strategy according to the detection result.
    [038]. In other words, in this embodiment, after a detection result with respect to pressure is obtained, the pistol-shaped loading coupler can make the detection result contained in a control signal and send the control signal to the loading cell. . The charging cell can obtain the detection result from the control signal after receiving the control signal. Subsequently, the loading stack can determine a loading control strategy according to the detection result. An operation corresponding to a loading control strategy is then performed.
    [039]. In an embodiment in which the determination of a loading control strategy is completed by the pistol-shaped loading coupler itself, step S12 can
    Petition 870160077050, of 12/19/2016, p. 20/46
    12/24 include:
    [040]. determining a loading control strategy according to a detection result; and [041]. sending a control signal including the charge control strategy to the charging stack connected to the pistol-shaped charging coupler.
    [042]. That is, in this embodiment, after the pistol-shaped loading coupler obtains a detection result with respect to pressure, the pistol-shaped loading coupler itself determines a loading control strategy according to the detection result. Subsequently, the pistol-shaped loading coupler can carry out a loading control strategy contained in a control signal and send the control signal to the loading cell. The charge stack can obtain a charge control strategy from the control signal after receiving the control signal, and directly performs an operation corresponding to a charge control strategy.
    [043]. As an example, as shown in figure 2, the pistol-shaped charging coupler 20 can complete the signal transmission with the charging cell by means of, for example, a signal transmission wire 30.
    [044]. In the present invention, if the determination of a loading control strategy is achieved by the pistol-shaped loading coupler itself or by the loading stack, a loading control strategy can be determined as follows.
    [045]. When the detection result indicates that a magnitude of pressure at the latch knob is greater than a first preset pressure limit value, and the pressure duration is longer than
    Petition 870160077050, of 12/19/2016, p. 21/46
    13/24 the first preset duration, a charging control strategy is determined as decreasing a charging current. As an example, the first pressure limit value can be adjusted to a minimum pressure value that can be detected by the action detection device 10. In other embodiments, the first pressure limit value can also be adjusted to other values.
    [046]. Alternatively or additionally, when the detection result indicates that a pressure magnitude is greater than a second preset pressure limit value, and the pressure duration is longer than the second preset duration, a control strategy charging time is determined as charging interruption, the second preset duration being longer than the first preset duration.
    [047]. In the present invention, the first preset duration and the second preset duration can both be adjusted according to current requirements, while the second preset duration is adjusted to be longer than a first preset duration. As an example, a first preset duration is 5s, and the second preset duration is 10s.
    [048]. Alternatively or additionally, when the detection result indicates that a pressure magnitude is greater than a third preset pressure limit value, and the pressure frequency is greater than a preset frequency limit value, a Charge control is determined according to the number of times the pressure is applied, such as suspending charging or heating a battery. Specifically, the load suspension control strategy can be, for example, waiting to be activated for automatic loading or reloading after a predetermined duration. THE
    Petition 870160077050, of 12/19/2016, p. 22/46
    14/24 A battery's heating control strategy can be, for example, automatic activation control for charging after heating a battery to a predetermined temperature. [049]. For example, when it is detected that the latch button is pressed (higher than the third pressure limit value) twice within 1s, a loading control strategy is determined as a loading suspension; or, when it is detected that the latch button is pressed (higher than the third pressure limit value) three times within 1s, a charge control strategy is determined as heating a battery.
    [050]. In this way, a user can perform different control requirements, for example, reducing a charging current, interrupting charging, suspending charging or heating a battery, by pressing the pistol-shaped charging coupler latch button to different durations or at different time intervals. The pistol-shaped loading coupler or the loading stack can determine corresponding loading control strategies according to the pressure detection results on the latch button, and can perform corresponding operations, thus meeting the requirements of the user.
    [051]. In addition, in the present invention, an electronic latch can be provided on the pistol-shaped loading coupler. The electronic latch is configured to attach the pistol-shaped charging coupler to a vehicle charging base during charging, thus preventing the separation of the pistol-shaped charging coupler from the vehicle charging base during charging. Since the electronic latch is used to take the place of an existing mechanical latch, electrical control can be done on the electronic latch to control whether the coupler
    Petition 870160077050, of 12/19/2016, p. 23/46
    15/24 pistol-shaped loading can be pulled from the vehicle loading base.
    [052]. In an optional embodiment of the present invention, the detection result is also used to determine an electronic closure control strategy for the electronic latch of the pistol-shaped loading coupler. Specifically, the electronic lock control strategy can be used to indicate whether or not it allows the electronic lock to be unlocked.
    [053]. In one embodiment, the electronic lock control strategy can be determined by the pistol-shaped loading coupler itself according to the detection result. As an example, the pistol-shaped loading coupler can determine the electronic lock control strategy such as unlocking the electronic lock when the detection result indicates that the magnitude of the pressure on the latch button is greater than the third limit value pressure preset, and the pressure duration is longer than a third preset duration. Subsequently, unlocking the electronic lock on the pistol-shaped loading coupler is activated.
    [054]. Alternatively, in another embodiment, the electronic closure control strategy can be determined by the charging stack according to the detection result. As an example, as described above, the pistol-shaped loading coupler can enable the detection result contained in a control signal and send the control signal to the loading cell. In this case, the loading stack can also determine the electronic closing control strategy for the pistol-shaped loading coupler according to the detection result. For example, the loading stack can determine the electronic lock control strategy such as unlocking the lock
    Petition 870160077050, of 12/19/2016, p. 24/46
    16/24 electronic when the detection result indicates that the magnitude of the pressure on the latch knob is greater than the third preset pressure and the duration of the pressure is greater than a third preset duration.
    [055]. Subsequently, the loading stack can send the determined electronic closing control strategy to the pistol-shaped loading coupler. After the pistol-shaped loading coupler receives the electronic lock control strategy, if the electronic lock control strategy indicates unlocking the electronic lock, the pistol-shaped loading coupler will activate the unlocking of the electronic lock.
    [056]. After unlocking the electronic lock, the pistol-shaped loading coupler can be pulled; or otherwise, the pistol-shaped loading coupler cannot be pulled.
    [057]. Therefore, when the second preset duration is equal to the third preset duration, the second pressure limit value is equal to the third pressure limit value, and the pressure duration is longer than the third preset duration, Automatic unlocking of the electronic lock can also be done to let a user pull the pistol-shaped charging coupler, in addition to controlling the interruption of the charging process. In this way, the risks caused by pulling the loaded pistol-shaped loading coupler can be effectively avoided by guaranteeing the life of the pistol-shaped loading coupler and the vehicle loading socket, protecting the safety of people, and improvement while charging the electric vehicle.
    [058]. Figure 3 is a flow chart of a loading control method provided in accordance with another embodiment of the present invention, in which the loading control method can
