It should be understood that the specific embodiments described herein are intended to be illustrative only and are not intended to be limiting. It will be apparent to one skilled in the art that the present application may be practiced without some of these specific details. The following description of the embodiments is merely intended to provide a better understanding of the present application by illustrating examples thereof.
It is noted that, herein, relational terms such as first and second, and the like may be used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions. Also, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus.

In order to solve the problems of the prior art, embodiments of the present application provide a charging method, an apparatus, a device, and a computer-readable storage medium. The charging method can be applied to the architecture shown in fig. 1, and is specifically described in detail with reference to fig. 1.
Fig. 1 illustrates an example diagram of an example of a charging scenario provided herein.
As shown in fig. 1, in the charging scenario, at least one charging vehicle 10, one power supply vehicle 20, and one charging apparatus 30 are included. The power supply vehicle 20 can supply power to the charging vehicle 10 through the charging device 30. During the power supply, the power supply vehicle 20 may activate the range extender to supply the high-power direct current to the charging vehicle 10.
According to the application scenario, the following describes in detail the charging method provided by the embodiment of the present application with reference to fig. 2 to 3, and it should be noted that, in the charging method provided by the embodiment of the present application, the execution subject may include a charging device and a power supply vehicle. Next, a charging method in which the execution subject is a charging device will be described in detail first.
Fig. 2 shows a schematic flowchart of an embodiment of a charging method provided in the present application, and it should be noted that the charging method is applied to a controller in a charging device, and the charging device may further include a charging line. As shown in fig. 2, the charging method may include the steps of:
s210, sending a pre-charging signal to the power supply vehicle and the charging vehicle under the condition that the charging line is connected with the charging vehicle and the power supply vehicle, so that the power supply vehicle supplies power to the charging vehicle through the charging line at a first voltage, and controlling a range extender on the power supply vehicle to start;
s220, in the process of pre-charging, under the condition that a leakage signal on a charging line is not received, a normal charging signal is sent to the power supply vehicle, so that the power supply vehicle controls the range extender to enter an idling state, and charging voltage is converted from first voltage to second voltage to supply power to the power supply vehicle; the first voltage is higher than a preset threshold and higher than the second voltage.
Thus, after the controller in the charging device monitors that the charging line is connected with the charging vehicle and the power supply vehicle, a pre-charge signal is sent to the power supply vehicle, so that the power supply vehicle starts the range extender and supplies power to the charging vehicle at the first voltage. And under the condition that the controller determines that the charging circuit has no electric leakage in the pre-charging process, sending a normal charging signal to the power supply vehicle so that the power supply vehicle controls the range extender to enter an idling state and supply power to the charging vehicle at a second voltage. The charging vehicle is powered by the power supply vehicle with the range extender, so that the power supply vehicle can output direct current with larger power, and the charging safety of the power supply vehicle in the process of outputting high-power direct current can be ensured because the leakage detection is carried out on the charging circuit before normal charging, so that the power supply of the high-power direct current can be realized, and the charging efficiency of the vehicle is further improved.
In some embodiments, the controller may detect whether the charging line connects the charging vehicle and the power supply vehicle by receiving the connection signal in S210. Wherein, the connection signal may include that the charging vehicle and the power supply vehicle are transmitted to the controller by the charging line after the charging line is connected.
In some embodiments, in the present application, since the charging vehicle is powered by the power supply vehicle with the range extender, and the power supply vehicle with the range extender can output high-voltage direct current, the insulation performance of the charging line needs to be detected first.
In the process of detecting the insulation performance of the charging line, the controller may include a communication device, and the controller may transmit the precharge signal to the electric-powered vehicle and the charging vehicle through the communication device. Wherein the pre-charge signal may comprise a high voltage charge signal.
In some embodiments, the first voltage may comprise a high voltage.
After the power-supplying vehicle receives the pre-charge signal, a high voltage may be output to the charging vehicle through the charging line. In order to output a high voltage to the electric supply vehicle, the electric supply vehicle may control a range extender provided in the electric supply vehicle to output at a higher rotation speed.
In some embodiments, the charging circuit may further include an electronic lock, which may be disposed at a connection of the charging circuit to the power supply vehicle and the charging vehicle. Under the condition that the controller monitors that the charging line is connected with both the charging vehicle and the power supply vehicle, the electronic lock can be controlled to be locked.
Therefore, before the charging is carried out by the charging line, after the charging line is connected with the charging vehicle and the power supply vehicle, the locking of the charging line with the charging vehicle and the power supply vehicle is completed by the electronic lock, and the charging interruption caused by disconnection of the charging line in the later charging process can be avoided. Further, the problem that after the charging circuit is disconnected, the charged charging circuit threatens the personal safety of a user can be avoided.
In some embodiments, in S220, the pre-charging process may include a charging process of a high voltage within a preset time period set by the controller, and the time of the pre-charging process may be set to 5 seconds, for example.
In some embodiments, the charging circuit may further include a leakage detection module, a pre-charging circuit, and a leakage resistor. The leakage resistor is arranged on the pre-charging loop, after the controller monitors that the charging circuit and the charging vehicle are connected with the power supply vehicle, the relay on the pre-charging loop can be controlled to be closed, and then the high voltage output by the power supply vehicle flows through the leakage resistor arranged on the pre-charging loop through the pre-charging loop. Then the insulation detection module can detect the resistance value of the leakage resistor, and then the leakage detection of the charging loop is completed.
In some embodiments, a normal charge signal may be sent to the powered vehicle in the event that the controller does not receive the leakage signal. The transmission process of the normal charging signal is the same as the transmission process of the precharge signal in the above embodiment, and is not described again here.
In some embodiments, when the electric supply vehicle receives the normal charging signal, the rotational speed of the range extender may be controlled to be reduced so that the second voltage having the lower voltage is output to the charging vehicle.
In some embodiments, the preset threshold may include a voltage value commonly used in the industry to detect charging lines. The second voltage can comprise a voltage value commonly used in the direct current quick charging process in the industry.
In some embodiments, after S220, the charging method may further include:
when the charging abnormality signal is received, a power supply stop signal is transmitted to the power supply vehicle to stop the power supply of the power supply vehicle.
In some embodiments, the charge anomaly signal includes at least one of:
the charging circuit sends overvoltage signal, overcurrent signal, overheat signal, leakage signal or stop signal that power supply vehicle or charging vehicle sent.
In some specific examples, the charging circuit may further include a voltage detection module, a current detection module, a temperature detection module, a leakage detection module, and a charging circuit, wherein the voltage detection module, the current detection module, the temperature detection module, and the leakage detection module may detect a voltage value, a current value, a temperature value, and a leakage value on the charging circuit, and then send the detection result to the controller.
The charging circuit may include a circuit different from the pre-charging circuit, and the controller may control the relay on the charging circuit to be opened and the relay on the pre-charging circuit to be closed after the controller transmits the normal charging signal to the powered vehicle, so that the current corresponding to the second voltage flows from the charging circuit to the powered vehicle. After the controller receives the charging abnormality signal, the controller may control the relay on the charging loop to be turned off, so that the power supply vehicle stops supplying power to the charging vehicle.
In some embodiments, the power supply vehicle may control the range extender to stop moving after receiving the power supply stop signal to stop supplying power to the charging vehicle.
Thus, after the controller receives the charging abnormality signal, the charging stop signal is transmitted to the power supply vehicle, so that the power supply vehicle stops supplying power to the charging vehicle. Therefore, the charging abnormal condition can be timely processed in the vehicle charging process, and damage to the life and property safety of a user caused by charging abnormality is effectively prevented.
In some embodiments, the charging method may further include:
receiving the required electric quantity sent by the charging vehicle;
determining the charging time required by the charging vehicle based on the required electric quantity, the voltage value in the charging line and the current value in the charging line;
and when the charging time reaches the charging time period, sending a power supply stopping signal to the power supply vehicle so as to stop the power supply of the power supply vehicle.
In some embodiments, the controller may receive the required amount of power transmitted from the charging vehicle through a communication device provided on the controller. The required electric quantity can include a difference value between the full electric quantity of the charging vehicle and the current electric quantity, and also can include an electric quantity which is set by a user definition corresponding to the charging vehicle.
In some embodiments, the method for obtaining the voltage value and the current value in the charging line has been described in detail in the above embodiments, and is not described herein again.
In some specific examples, the charging power may be determined based on the voltage value and the current value, and then the time period during which the charging vehicle needs to be charged may be determined based on the ratio of the required amount of electricity transmitted by the charging vehicle to the charging power.
In some embodiments, the controller may determine whether the current charging period has reached the determined required charging period based on the determined charging period and the total period of the current charging, and in the case of reaching the required charging period, transmit a power supply stop signal to the electric vehicle to stop the electric vehicle from supplying power. The technical solution of sending the power supply stop signal to the power supply vehicle to stop the power supply of the power supply vehicle has been described in detail in the above embodiments, and is not described herein again.
Therefore, the controller obtains the required electric quantity of the charging vehicle, obtains the current value and the voltage value of the charging line, determines the time needing to be charged according to the required electric quantity, the current value and the voltage value, and sends a power supply stopping signal to the power supply vehicle after the charging time is up so that the power supply vehicle stops supplying power. The controller can control the total value of the power supply electric quantity, and the problem of electric quantity waste caused by overlarge power supply quantity of the power supply vehicle to the charging vehicle is avoided.
In some embodiments, the charging method may further include: sending the charging parameters to at least one of a main controller of the power supply vehicle, a main controller of the charging vehicle or user intelligent equipment; the charging parameter comprises at least one of a time length required to be charged, a voltage value, a current value, a completed charging amount or charging efficiency; the completed charge amount and the charging efficiency are determined based on the voltage value and the current value.
In some embodiments, the method for obtaining the charging parameter has been described in detail in the foregoing embodiments, and is not described herein again.
Therefore, at least one of the charging parameters sent to the main controller of the power supply vehicle, the main controller of the charging vehicle or the user intelligent equipment can enable a user corresponding to the power supply vehicle or the charging vehicle to timely acquire the charging parameters of the current charging circuit, and further enable the user to control the charging process according to the acquired charging parameters, so that the user experience is improved.
In some specific examples, the charging device may further include a display device, and the controller may transmit the charging parameter to the display device to cause the display device to display the charging parameter.
Fig. 3 is a schematic flow chart illustrating another embodiment of a charging method provided by the present application, which may be applied to an electric vehicle. As shown in fig. 3, the charging method may include the steps of:
s310, under the condition of receiving a pre-charging signal sent by charging equipment, supplying power to a charging vehicle through a charging line in the charging equipment by using a first voltage, and controlling a range extender on the power supply vehicle to start;
s320, under the condition of receiving a normal charging signal sent by the charging equipment, controlling the range extender to enter an idling state, and converting the charging voltage from the first voltage into a second voltage to supply power to the charging vehicle; the first voltage is higher than a preset threshold and higher than the second voltage.
Thus, the charging vehicle is pre-charged by the power supply vehicle at a first voltage according to the pre-charge signal transmitted by the charging device, and then after the pre-charging is completed, the charging vehicle is supplied with power at a second voltage according to the normal charge signal transmitted by the power supply vehicle. The power supply vehicle timely responds to the signal sent by the charging equipment to charge the charging vehicle with different voltage values, so that the cooperativity of the power supply vehicle and the charging equipment can be improved in the charging process. Further, the charging efficiency is improved.
In some embodiments, S310 and S320 have already been described in detail in the above embodiments, and are not described herein again.
It should be noted that the application scenarios described in the foregoing disclosure are for more clearly illustrating the technical solutions of the embodiments of the disclosure, and do not constitute a limitation of the technical solutions provided in the embodiments of the disclosure, and as a person of ordinary skill in the art knows new application scenarios, the technical solutions provided in the embodiments of the disclosure are also applicable to similar technical problems.

Thus, after the controller in the charging device monitors that the charging line is connected with the charging vehicle and the power supply vehicle, a pre-charge signal is sent to the power supply vehicle, so that the power supply vehicle starts the range extender and supplies power to the charging vehicle at the first voltage. And under the condition that the controller determines that the charging circuit has no electric leakage in the pre-charging process, sending a normal charging signal to the power supply vehicle so that the power supply vehicle controls the range extender to enter an idling state and supply power to the charging vehicle at a second voltage. The charging vehicle is powered by the power supply vehicle with the range extender, so that the power supply vehicle can output direct current with larger power, and the charging safety of the power supply vehicle in the process of outputting high-power direct current can be ensured because the leakage detection is carried out on the charging circuit before normal charging, so that the power supply of the high-power direct current can be realized, and the charging efficiency of the vehicle is further improved.
In some embodiments, the charging device may further include:
and the third sending module can be used for sending a power supply stopping signal to the power supply vehicle to stop the power supply of the power supply vehicle when the charging abnormal signal is received after the normal charging signal is sent to the power supply vehicle.
In some embodiments, the charge abnormality signal may include at least one of:
the charging circuit sends overvoltage signal, overcurrent signal, overheat signal, leakage signal or stop signal that power supply vehicle or charging vehicle sent.
Thus, after the controller receives the charging abnormality signal, the charging stop signal is transmitted to the power supply vehicle, so that the power supply vehicle stops supplying power to the charging vehicle. Therefore, the charging abnormal condition can be timely processed in the vehicle charging process, and damage to the life and property safety of a user caused by charging abnormality is effectively prevented.
In some embodiments, the charging device may further include:
the receiving module can be used for receiving the required electric quantity sent by the charging vehicle;
the determining module can be used for determining the charging time length required by the charging vehicle based on the required electric quantity, the voltage value in the charging line and the current value in the charging line;
and the fourth sending module can be used for sending a power supply stopping signal to the power supply vehicle to stop the power supply of the power supply vehicle when the charging time reaches the charging time period.
Therefore, the controller obtains the required electric quantity of the charging vehicle, obtains the current value and the voltage value of the charging line, determines the time needing to be charged according to the required electric quantity, the current value and the voltage value, and sends a power supply stopping signal to the power supply vehicle after the charging time is up so that the power supply vehicle stops supplying power. The controller can control the total value of the power supply electric quantity, and the problem of electric quantity waste caused by overlarge power supply quantity of the power supply vehicle to the charging vehicle is avoided.
In some embodiments, the charging device may further include:
the fifth sending module can be used for sending the charging parameters to at least one of a main controller of the power supply vehicle, a main controller of the charging vehicle or user intelligent equipment; the charging parameter may include at least one of a time period during which charging is required, a voltage value, a current value, a completed charge amount, or a charging efficiency; the completed charge amount and the charging efficiency are determined based on the voltage value and the current value.
Therefore, at least one of the charging parameters sent to the main controller of the power supply vehicle, the main controller of the charging vehicle or the user intelligent equipment can enable a user corresponding to the power supply vehicle or the charging vehicle to timely acquire the charging parameters of the current charging circuit, and further enable the user to control the charging process according to the acquired charging parameters, so that the user experience is improved.
