The embodiments described below by referring to the accompanying drawings are exemplary and are only used to explain the present utility model and should not be construed as a limitation to the present utility model.

[0039] The charging of new energy vehicles mainly depends on fixed charging piles, which are usually installed at fixed locations such as parking lots, residential areas, and commercial areas. Although fixed charging piles can provide stable power supply, they have obvious spatial limitations.

[0040] In view of this, the embodiments of the present utility model provide a charging device and a vehicle. The charging device is set as a movable structure and can be carried along with the vehicle, without being restricted by space.

[0043] The housing assembly 110 is the main support structure of the charging device 100. The housing assembly 110 has a receiving cavity for receiving and protecting other partial structures of the charging device 100. The housing assembly 110 is a movable structure, that is, users can transfer the spatial position of the charging device 100 by moving the housing assembly 110. For example, rollers 112 may be provided on the housing assembly 110, and users can move the charging device 100 by pushing the housing assembly 110. Or, the housing assembly 110 may be arranged on a movable base, and users can move the charging device 100 by controlling the movement of the base.

[0044] The energy storage device 120 is located in the accommodation cavity. The energy storage device 120 may include a plurality of batteries to provide backup electrical energy for the battery of the electric vehicle.

[0045] When charging the electric vehicle, the charging assembly 130 provides an electrical connection between the electric vehicle and the energy storage device 120. The charging assembly 130 may include a power supply wire harness and a charging gun. The power supply wire harness is electrically connected to the energy storage device 120, the charging gun is connected to the power supply wire harness, and the charging gun is detachably disposed outside the housing assembly 110. The charging gun is configured to be connected to the charging interface of the electric vehicle.

[0046] The control system 140 is respectively connected to the energy storage device 120 and the charging gun to control the operating state of the charging device 100.

[0047] The user can move the charging device 100 of the present utility model to the electric vehicle for storage and use along with the vehicle. When the user encounters a situation where the electric vehicle runs out of power and cannot drive the electric vehicle to a parking lot, service area or other places for charging (for example, when the electric vehicle runs out of power and is exactly in the wild), the user can connect the charging gun of the charging device 100 to the charging interface on the electric vehicle, operate the control system 140, and charge the electric vehicle, which is convenient for charging and is beneficial to improving user satisfaction.

[0048] Moreover, during driving, the user can also connect the charging gun of the charging device 100 to the charging interface of the electric vehicle. In this way, the electric vehicle can continuously supply power to the battery of the electric vehicle through the charging device 100 during driving, without the need for parking charging, and the user's journey will not be interrupted, thereby improving user satisfaction.

[0049] Reference Figure 1 and Figure 2 In some embodiments, the charging device 100 may further include: a boost device 160 and a charging wire harness.

[0050] The boost device 160 may be a boost converter. The boost device 160 is disposed between the energy storage device 120 and the charging assembly 130 to adjust the output voltage of the energy storage device 120 and boost the output voltage of the energy storage device 120 to a voltage level suitable for the charging assembly 130, thereby ensuring the stability and efficiency of the charging process; enabling the energy storage device 120 to charge different models of electric vehicles, improving the versatility of the charging device 100. Moreover, the boost device 160 can stabilize the voltage output by the energy storage device 120, avoid damage to the energy storage device 120 due to voltage fluctuations, and thus extend the service life of the energy storage device 120.

[0051] The charging harness is connected to the energy storage device 120 and is adapted to be connected to an external power source for charging. Users can conveniently connect the energy storage device 120 to an external power source such as a household power supply or a public charging pile through the charging harness to charge, improving the convenience of the charging process of the charging device 100. Users can charge the energy storage device 120 through the charging harness, enabling the charging device 100 to be reused.

[0052] Understandably, the charging harness and the power supply harness can be used interchangeably. In the case of damage to the power supply harness, users can also use the charging harness to connect the charging gun to the energy storage device 120 to ensure that the electric vehicle can obtain power supply in a timely manner and avoid the interruption of the journey due to insufficient power in the electric vehicle.

[0053] The charging device 100 may further include a solar panel. The solar panel can be disposed on the top of the shell main body 111 of the housing assembly 110 and is electrically connected to the energy storage device 120 to convert light energy into electrical energy and charge the energy storage device 120. By providing the solar panel, another way to charge the charging device 100 is provided for users. The solar panel can convert light energy into electrical energy, providing a green and environmentally friendly power source for the energy storage device 120, reducing the dependence on traditional power resources, reducing carbon emissions, and moreover, through the solar panel, the charging device 100 can achieve automatic charging outdoors or in a powerless environment without relying on an external power source, enhancing the independence and flexibility of the charging device 100.

[0054] Understandably, the charging device 100 in this embodiment may be provided with only one of the power supply harness and the solar panel, or may have both the power supply harness and the solar panel to achieve the effect of charging the energy storage device 120.

[0055] Reference Figure 1 , in some embodiments, the housing assembly 110 of the charging device 100 may include: a shell main body 111, rollers 112, and a push rod 113.

[0056] The housing main body 111 defines an accommodation cavity. The roller 112 is provided at the bottom of the housing main body 111 and is rotatable relative to the housing main body 111, reducing the contact area between the housing main body 111 and the ground, making it more labor-saving and convenient for the user to move the housing main body 111. The push rod 113 is telescopically provided on the housing main body 111. For example, the push rod 113 is provided at one end of the housing main body 111 along the length direction. The housing main body 111 defines a receiving groove along the height direction of the housing main body 111, and the push rod 113 is telescopically arranged in the receiving groove. When moving the charging device 100, the user only needs to pull out the push rod 113 from the receiving groove and apply a horizontal thrust to the push rod 113 to push the housing main body 111 to move. The charging device 100 is easy to operate, and the housing assembly 110 of this embodiment has a simple structure and is convenient for large-scale production.

[0057] Continuing to refer to Figure 1 , in some embodiments, the charging device 100 may further include a fire extinguishing device 150. The fire extinguishing device 150 may be a dry powder fire extinguisher or an ABC dry powder fire extinguisher. The fire extinguishing device 150 is detachably provided on the housing assembly 110. For example, an elastic clip is provided on the housing main body 111, and the fire extinguishing device 150 is clamped in the elastic clip. When a thermal runaway occurs in the energy storage device 120, the user can remove the fire extinguishing device 150 to quickly extinguish the fire.

[0058] During the use of the charging device 100, once overheating occurs, or even a fire breaks out, the fire extinguishing device 150 can be used to extinguish the thermal runaway at the energy storage device 120. In this way, the safety during the use of the charging device 100 can be greatly improved.

[0059] Refer to Figure 3 , in some embodiments, the control system 140 may include a main control unit 141. The main control unit 141 is used to control the operating state of the charging device 100. The operating state may include the start-stop state of the charging device 100, that is, the main control unit 141 controls the start and end of the process of the energy storage device 120 charging the electric vehicle through the charging gun. It can be understood that the main control unit 141 can also control the start and end of the charging process of the energy storage device 120. By controlling the start-stop state of the charging device 100 through the main control unit 141, overcharging or over-discharging of the battery can be avoided, which is beneficial to extending the service life of the device. In addition, the main control unit 141 can also monitor the operating state of the charging device 100 and cut off the power in time when an abnormal situation occurs, which is beneficial to improving the safety of the charging process.

[0060] In some embodiments, the control system 140 may further include a discharge control unit 142. The discharge control unit 142 is electrically connected to the energy storage device 120 to control the discharge state of the energy storage device 120. The discharge state includes: discharge start / stop, discharge power, discharge current, and discharge voltage. The discharge control unit 142 can dynamically adjust the discharge power and discharge current according to the battery requirements of the electric vehicle. For example, when the battery level of the current electric vehicle is 20%, the battery level is relatively low at this time, the internal impedance of the battery is high, and the current acceptance ability is weak. The discharge control unit 142 controls the energy storage device 120 to charge with a lower discharge power and current. As the charging process progresses, the battery level gradually rises to 50%. At this time, the internal impedance of the battery decreases, and the current acceptance ability increases. The discharge control unit 142 controls the energy storage device 120 to charge with a higher discharge power and current. Then, the battery level gradually rises to 80%. At this time, the internal impedance of the battery increases, and the current acceptance ability decreases. The discharge control unit 142 controls the energy storage device 120 to charge with a lower discharge power and current. This improves the discharge efficiency, optimizes the charging process of the electric vehicle, and reduces energy loss.

[0061] In some embodiments, the control system 140 includes a human-machine interaction unit 143. The human-machine interaction unit 143 is disposed on the housing assembly 110. The human-machine interaction unit 143 is at least used to input control instructions and display the operating state of the charging device 100. The human-machine interaction unit 143 may include an operation interface. The operation interface may be a button-type interface or a touch-screen interface. The user inputs control instructions through the operation interface to control the charging and discharging process of the charging device 100. During the charging process of the electric vehicle, the user can obtain the operating state of the charging device 100 from the human-machine interaction unit 143. Among them, the operating state may include data such as the remaining power of the current energy storage device 120, charging current, and charging voltage, improving the user-friendliness of the charging device 100 and thus improving the user's satisfaction.

[0062] In some embodiments, the control system 140 further includes a data acquisition unit 144. The data acquisition unit 144 is connected to the energy storage device 120 to acquire the working condition information of the energy storage device 120. The working condition information includes at least one of current, voltage, temperature, and pressure. For example, the data acquisition unit 144 can acquire one working condition of the current, voltage, temperature, and pressure of the energy storage device 120, or can acquire all the data of two, three, or even four working conditions.

[0063] By acquiring the working condition information of the energy storage device 120 and real-time monitoring of key parameters such as current, voltage, and temperature, it can ensure that the charging device 100 operates under the best working conditions, avoid overheating of the charging device 100 during the charging process of the electric vehicle, and improve the use safety of the device.

[0064] Understandably, when abnormal conditions such as thermal runaway occur during the charging process of the charging device 100 for an electric vehicle, the data acquisition unit can collect and store the operating condition information of the energy storage device 120 during the thermal runaway process, which is convenient for engineers to analyze.

[0065] Furthermore, the control system 140 includes a safety control unit 145, and the safety control unit 145 is communicatively connected to the fire extinguishing device 150 to control the operating state of the fire extinguishing device 150. For example: The safety control unit 145 may include at least one sensor and a trigger. The sensor is used to collect abnormal operating conditions of the charging device 100, and the trigger is provided on the fire extinguishing device 150. The sensor is communicatively connected to the trigger. When the charging device 100 experiences a thermal runaway situation, the trigger controls the operation of the fire extinguishing device 150 to extinguish the fire. By controlling the fire extinguishing device 150 to perform fire extinguishing operations through the safety control unit 145, the response is automated, the reaction speed is fast, the expansion of the thermal runaway situation is avoided, and losses can be minimized to the greatest extent.

[0066] The working principle of the charging device 100 of the present utility model is as follows:

[0067] The user fully charges the energy storage device 120 through a solar panel or a power supply harness, and then moves the charging device 100 onto the electric vehicle through the push rod 113 for use with the vehicle. During the driving process of the electric vehicle, the user can connect the charging gun of the charging device 100 to the charging interface of the electric vehicle, and the electric vehicle is continuously powered by the charging device 100 during the driving process.

[0068] In a second aspect, an embodiment of the present utility model further provides a vehicle.
