Detailed Description

It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

It is noted that relative terms such as "first," "second," and the like may be used to describe various components, but these terms are not intended to limit the components. These terms are only used to distinguish one component from another component. For example, a first element could be termed a second element, and, similarly, a second element could be termed a first element, without departing from the scope of the present invention. The term "and/or" refers to a combination of any one or more of the associated items and the descriptive items.

The application scenario of the multi-gun charging pile charging control method comprises a charging pile, a mobile terminal and a device to be charged. The mobile terminal can be a mobile phone, an IPAD and other intelligent equipment; the device to be charged comprises an electric vehicle, including but not limited to an electric car and an electric bus. In the following embodiments, three charging guns are used for specific description, and actually, four charging guns, five charging guns, and the like can be further provided on the charging pile, and the control method is suitable for the three charging guns, which is not described herein again.

Referring to fig. 2, fig. 2 is a schematic flowchart illustrating a charging control method for a multi-gun charging pile according to embodiment 1 of the present invention; the charging control method of the multi-gun charging pile is suitable for one charging pile, and the charging pile is at least provided with a first charging gun and a second charging gun, namely, a single charging pile is provided with a plurality of charging guns.

Step S10, acquiring the use state of the charging pile;

in this embodiment, the use state includes an idle state or an occupied state. The idle state indicates that all charging guns on the charging pile are not used. The occupied state indicates that at least one charging gun on the charging post is performing charging (in use).

Step S20, if the usage status is an idle status, detecting whether a first input signal exists, where the first input signal is generated when the first charging gun contacts a charging interface of a first device to be charged;

in this embodiment, if the use state is an idle state, it indicates that all charging guns on the charging pile are not used, and at this time, it is detected whether a first input signal exists every preset time period. The first input signal is generated when the first charging gun contacts with a charging interface of a first device to be charged. For example, when a first user connects a charging gun on the charging pile to a first device to be charged, the first device to be charged feeds back a first input signal to the charging pile. The first input signal may be a first CP signal including, but not limited to, a PLC signal on CCS1, CCS2, and a PWM signal in ac charging; the charging interface of the first device to be charged includes, but is not limited to, a CCS1 charging interface, a CCS2 charging interface, and an ac charging interface.

Step S30, if the first input signal exists, the first charging loop corresponding to the first charging gun is turned on, so that the voltage provided by the power supply terminal is transmitted to the first device to be charged through the first charging loop.

In this embodiment, if the control unit in the charging pile detects the first input signal, the control unit determines the charging loop to be conducted according to the loop identification information carried by the first input signal and generates a corresponding first conversion signal, and the first conversion signal is transmitted to the signal processing unit through the protocol conversion unit to conduct the first charging loop corresponding to the loop identification information. For example, if the first input signal is from the first charging circuit, the first conversion signal is a conversion signal corresponding to the first charging circuit, so that the signal processing unit conducts the first charging circuit according to the first conversion signal.

The charging control method for the multi-gun charging pile is suitable for a single-pile multi-gun charging pile structure. Based on the fact that only a single protocol conversion unit is used (compared with a plurality of traditional protocol conversion units, the single protocol conversion unit generates fewer conversion signals), the whole circuit can be simplified, and the realization of the charging pile is facilitated. And only when the first input signal is detected (when the device to be charged is connected), the corresponding charging loop is conducted, so that the service life of the switch is ensured, the control unit/the protocol conversion unit can properly accelerate the action time of the switch, and the time delay brought by judging the connection state with the device to be charged is reduced.

Referring to fig. 3, fig. 3 is a flowchart illustrating a charging control method for a multi-gun charging pile according to embodiment 2 of the present invention. In embodiment 2, steps S200 to S203 are added to embodiment 1. Should fill and still have the third rifle that charges on the electric pile, after obtaining the user state who fills electric pile, include:

step S200, if the using state is the occupied state, detecting whether the using state of the charging pile is changed;

in this embodiment, if the user state is the occupation state, it indicates that a charging gun of charging stake is in the user state. And detecting whether the use state of the charging pile changes every preset time period, so as to determine whether the charging pile completes the charging operation. Namely, the using state comprises an occupied state and an idle state, and when the charging pile is in the using state, the charging pile indicates that at least one charging gun exists on the charging pile and is charging; when the charging pile is in an idle state, the charging pile is indicated to receive a charging completion signal, namely the charging pile adjusts the use state to the idle state after receiving the charging completion signal.

Step S201, if the using state is changed from the occupying state to the idle state, detecting whether a second input signal and a third input signal exist;

if the using state is changed from the occupied state to the idle state, the first charging gun on the charging pile finishes the charging operation on the first device to be charged, and whether a second input signal and a third input signal exist is detected, wherein the second input signal is generated when the second charging gun is in contact with a charging interface of the second device to be charged, and the third input signal is generated when the third charging gun is in contact with a charging interface of the third device to be charged. Whether two devices to be charged (the second device to be charged and the third device to be charged) are both in the waiting charging state can be confirmed by the presence of the second input signal and the third input signal.

In this embodiment, the second input signal is generated when the second charging gun contacts a charging interface of a second device to be charged, the third input signal is generated when the third charging gun contacts a charging interface of a third device to be charged, and the occupation state indicates that the first charging gun of the charging pile is charging;

note that the second input signal may be a second CP signal, which includes but is not limited to a CCS1, a PLC signal on CCS2, and a PWM signal in ac charging; the charging interface of the second device to be charged includes, but is not limited to, a CCS1 charging interface, a CCS2 charging interface, and an ac charging interface. The third input signal may be a third CP signal including, but not limited to, a PLC signal on CCS1, CCS2, and a PWM signal in ac charging; the charging interface of the third device to be charged includes, but is not limited to, a CCS1 charging interface, a CCS2 charging interface, and an ac charging interface.

Step S202, if a second input signal and a third input signal exist, a second priority of the second charging gun and a third priority of the third charging gun are obtained;

in this embodiment, if the second input signal and the third input signal exist, it indicates that the second device to be charged and the third device to be charged are both in the waiting-to-charge state. At this time, a second priority of the second charging gun and a third priority of the third charging gun are obtained. Optionally, the second priority of the second charging gun is a first access time of accessing the charging pile according to the second input signal, and the third priority of the third charging gun is a second access time of accessing the third input signal to the charging pile. For example, the first access time of the second charging gun is 8 am 10 min, and the second priority of the second charging gun is 8 am 10 min. The second access time of the third charging gun is 8 points and 30 minutes, the third priority of the third charging gun is 8 points and 30 minutes, and the priority is represented by time, namely the principle of first-come first-charge is satisfied. The priority may also be determined according to the number of the charging gun, for example, if the number of the second charging gun is 2, the priority of the second charging gun is 2. The third charging gun is numbered 3, and the priority of the third charging gun is 3. Of course, the priority acquisition method is not limited to the above.

Step S203, determining a priority comparison result according to the second priority and the third priority;

in this embodiment, the priority comparison result includes a comparison result in which the second priority is better than the third priority or a comparison result in which the third priority is better than the second priority. It is apparent that different priority comparison results correspond to different charging operations.

And step S204, executing charging operation according to the priority comparison result.

In this embodiment, when the charging pile is switched from the occupied state to the idle state, that is, when the charging gun on the charging pile completes the charging operation, different charging operations are executed according to different priority comparison results.

According to the charging control method for the multi-gun charging pile, when a plurality of devices to be charged are in a waiting charging state, different charging operations are executed according to priority comparison results by obtaining the priorities corresponding to the plurality of charging guns of the plurality of devices to be charged. For example, the first charging with a high priority.

In the above embodiment, after step S203, a first charging priority signal is sent to the mobile terminal corresponding to the charging gun with a low priority, so as to prompt the user with the low priority, and it is necessary to wait for others to charge after charging; detecting whether a priority adjustment request is received, wherein the priority adjustment request is sent by a mobile terminal corresponding to a charging gun with low priority, the priority adjustment request can be exchanged by the mobile terminal corresponding to the charging gun with low priority through an account point mode, for example, a user can exchange a priority adjustment request through 10 points (accumulation of the points can be the charging times of the user), a charging pile forwards the received priority adjustment request to the mobile terminal corresponding to the charging gun with high priority to prompt the user with high charging priority, if the user considers that the user can give a gift, the user feeds a priority adjustment command back to the charging pile through the mobile terminal, and the charging pile adjusts the priority comparison result after receiving the feedback priority adjustment command (the adjustment mode can be the charging priority of two charging guns is exchanged), and executing the charging operation according to the adjusted priority comparison result, obviously, the charging gun can carry out point reward on the user who sends the priority adjustment command, and the 10 points are added to the user account of the user. Therefore, the effect that people who need to be charged urgently can be charged first after being authorized by means of priority adjustment is achieved.

Referring to fig. 9, fig. 9 shows an internal principle structure of a charging pile in each embodiment of the present invention, a signal processing unit, a protocol conversion unit and a control unit are disposed in the charging pile, a plurality of charging loops are disposed in the signal processing unit, and each charging loop is provided with a switch. Specifically, a first charging loop, a second charging loop and a third charging loop are arranged in the signal processing unit, a first switch is arranged in the first charging loop, a second switch is arranged in the second charging loop, and a third switch is arranged in the third charging loop; the control unit is used for communicating with a device to be charged, such as receiving a first input signal. The protocol conversion unit is used for receiving the conversion signal transmitted by the control unit and transmitting the conversion signal to the signal processing unit. The signal processing unit is used for controlling the on or off of the switch and correspondingly controlling the on or off of the charging loop.

Obviously, the internal principle structure of the charging pile in each embodiment of the invention is different from the internal principle block diagram in the existing charging pile mentioned in the background technology. Only one protocol conversion unit is utilized, and a plurality of charging loops are integrated in the signal processing unit, wherein each charging loop is provided with an independent controllable switch. The circuit structure can be greatly simplified, and the synchronism is realized on the execution steps of connection and disconnection.

The switch used in the signal processing unit is not limited to a relay, a MOS transistor, a thyristor, or other switching devices. The first charging gun is connected with the first charging loop, the second charging gun is connected with the second charging loop, and the third charging gun is connected with the third charging loop.

Referring to fig. 4, fig. 4 is a flowchart illustrating a charging control method for a multi-gun charging pile according to embodiment 3 of the present invention. Embodiment 3 is specifically defined as to the charging operation performed as a result of the priority comparison in embodiment 2. The performing of the charging operation according to the priority comparison result includes:

step S2031, the protocol conversion unit generates a first open signal and a first close signal according to the priority comparison result;

in this embodiment, the priority comparison result is a comparison result in which the second priority is better than the third priority. And a protocol conversion unit of the charging pile simultaneously generates a first opening signal and a first closing signal according to the priority comparison result.

Step S2032, the protocol conversion unit transmits the first disconnection signal to a signal processing unit; the first disconnection signal is used for triggering the signal processing unit to disconnect a first charging loop corresponding to the first charging gun;

step S2033, the protocol conversion unit sends the first close signal to the signal processing unit, where the first close signal is used to trigger the signal processing unit to turn on a second charging loop corresponding to the second charging gun.

In the present embodiment, a single protocol conversion unit is used as a generation subject of the first open signal and the first close signal. And synchronously transmitting the first opening signal and the first closing signal to the signal processing unit so that the signal processing unit synchronously executes corresponding opening operation and closing operation. The whole opening operation process only involves one protocol conversion unit, one switch of one charging loop and the signal processing unit, so that the closing efficiency of the opening process involving the switch is guaranteed. It should be noted here that the first close signal and the first open signal are generated synchronously, and generally, when one charging circuit needs to be opened, the other charging circuit needs to be opened. The first closing signal is matched with the first opening signal (a mapping relation exists), and the mapping relation is stored in a memory of the charging pile; when the first open signal is generated, the corresponding first close signal is also generated synchronously.

It should be noted that the protocol conversion unit in the present application may be a monitoring unit.

The application scenario of embodiment 3 is: for example, the first access time of the second charging gun is earlier than the second access time of the third charging gun, so that the priority of the second charging gun is better than the priority of the third charging gun. The generated first close signal is used to turn on a second charging loop corresponding to the second charging gun. Whereby the second device to be charged connected to the second charging gun is charged preferentially.

Fig. 5 shows a flowchart of a charging control method for a multi-gun charging pile according to embodiment 4 of the present invention. Embodiment 4 is specifically defined as the step of performing the charging operation according to the priority comparison result in embodiment 2. And embodiment 4 differs from embodiment 3 in that different charging operations are performed for different priority results. Specifically, the performing the charging operation according to the priority comparison result includes:

step S2034, the protocol conversion unit generates a second open signal and a second close signal according to the priority comparison result;

in this embodiment, the priority comparison result includes a comparison result in which the third priority is better than the second priority. And the control unit of the charging pile simultaneously generates a second opening signal and a second closing signal according to the priority comparison result.

Step S2035, the protocol conversion unit sends the second disconnection signal to the signal processing unit, where the second disconnection signal is used to trigger the signal processing unit to disconnect the first charging loop corresponding to the first charging gun;

step S2036, the protocol conversion unit sends the second close signal to the signal processing unit, where the second close signal is used to trigger the signal processing unit to turn on a third charging loop corresponding to the third charging gun.

In this embodiment, the protocol conversion unit is used as a main generation body of the open signal and the close signal. And synchronously sending the second opening signal and the second closing signal to the signal processing unit so that the signal processing unit synchronously executes corresponding opening operation. The whole opening operation process only involves one protocol conversion unit, one switch of one charging loop and the signal processing unit, so that the closing efficiency of the opening process involving the switch is guaranteed. It should be noted here that the second close signal and the second open signal are generated synchronously, and generally, when one charging circuit needs to be opened, the other charging circuit needs to be opened. The second closing signal is matched with the second opening signal (a mapping relation exists), and the mapping relation is stored in a memory of the charging pile; when the second open signal is generated, a corresponding second closed signal is also generated synchronously.

The application scenario of embodiment 4 is: for example, the second access time of the third charging gun is earlier than the first access time of the second charging gun, so that the priority of the third charging gun is better than that of the second charging gun. The generated second close signal is used to turn on a third charging loop corresponding to a third charging gun. Whereby the third device to be charged connected to the third charging gun is charged preferentially.

Fig. 6 is a schematic flowchart illustrating a charging control method for a multi-gun charging pile according to embodiment 5 of the present invention, where embodiment 5 differs from embodiment 3 in that, after the step of sending the first closing signal to the signal processing unit by the protocol conversion unit, the method includes:

step S2037, acquiring a charging voltage value in the second charging loop;

specifically, the charging voltage value in the second charging loop can be obtained through the voltage detection circuit;

step S2038, detecting whether the charging voltage value meets a voltage set value, wherein the voltage set value is a voltage value input to the charging pile by a second user through a second mobile terminal;

step S2039, if the charging voltage value does not meet the voltage setting value, sending a prompt message to the second mobile terminal.

In embodiment 5, it is mainly determined whether the charging voltage value meets a voltage set value by obtaining the charging voltage value in the second charging loop, and if the charging voltage value does not meet the voltage set value, a prompt message is sent to the second mobile terminal. So as to prompt the second user to charge the pile and to cause damage to the battery of the second device to be charged.

For example, the voltage value input by the second user is 300V, and after the charging pile performs the disconnection operation and the conduction operation, only the voltage originally provided to the output end of the power supply terminal of the first charging circuit is transferred to the second charging circuit, so that there is a problem that the voltage provided by the power supply terminal cannot meet the requirement of different charging voltages based on different specifications of the electric vehicle (for example, the voltage output by the power supply terminal to the second charging circuit is 220V), and there is a problem that the voltage provided by the power supply terminal cannot meet the requirement (the charging voltage is important to adapt to the battery of the electric vehicle, otherwise, the battery is easily damaged), so that embodiment 5 focuses on performing voltage detection on the second charging circuit that is just conducted, and if the voltage is not met, prompting the second user to inform the second user that the risk of damaging the battery of the second device to be charged exists in the current charging. At this point the second user may terminate the charging operation, thereby avoiding damage to the battery used in the second device to be charged.

Fig. 7 is a schematic flow chart illustrating a charging control method for a multi-gun charging pile according to embodiment 6 of the present invention, where embodiment 6 specifically defines the step of detecting whether a first input signal exists. The first input signal comprises a first CP signal, and the detecting whether the first input signal is present comprises:

step S205, performing voltage detection on a first receiving end of a first charging loop in the signal processing unit;

specifically, voltage detection is respectively performed on a first receiving end of a first charging loop in the signal processing unit every other preset time period;

step S206, acquiring the voltage change condition of the first receiving end;

specifically, the voltage change condition reflects whether an input signal is received at the receiving end, and the input of the input signal can cause the voltage at the receiving end to change; namely, the voltage change condition of the first receiving end comprises that the first receiving end has voltage change or the first receiving end does not have voltage change;

step S207, determining whether the first CP signal exists according to a voltage variation of the first receiving end.

Specifically, if the voltage variation condition of the first receiving end is that there is a voltage variation in the first receiving end, it may be determined that the first charging gun on the first charging loop corresponding to the first receiving end is inserted into the first device to be charged by the first user, and the first CP signal is from the charging interface of the first device to be charged.

In the above embodiment 6, the voltage detection is performed simultaneously for the corresponding receiving terminals on different charging loops, so as to accurately determine whether the charging gun corresponding to the charging loop is enabled.

Fig. 8 is a schematic flow chart of a charging control method for a multi-gun charging pile according to embodiment 7 of the present invention, where embodiment 7 specifically defines a step of obtaining a usage state of the charging pile, and specifically includes:

step S100, a communication signal is obtained, wherein the communication signal is a signal received by a control unit of the charging pile;

and S101, determining the using state of the charging pile according to the communication signal.

In this embodiment, the use state of the charging pile is determined by acquiring the communication signal. Because the communication signal is generated when the control unit of the charging pile is connected with the device to be charged and is different from the first input signal, the communication signal can accurately judge the use state of the charging pile.
