detailed description

Hereinafter, specific embodiments of the present disclosure will be described in detail with reference to the drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the disclosure, and are not intended to limit the disclosure.

FIG. 1 is a schematic diagram of a charging system 10 according to an embodiment of the present disclosure. As shown in FIG. 1, the charging system 10 includes a charging post 11 and a street lamp 12, and the street lamp 12 is communicatively connected to the charging post 11. The type of the charging pile 11 is not limited, and any type of charging pile can be used as the charging pile 11 in the embodiment of the present disclosure. In one embodiment, the charging post 11 is a wireless charging post.

In the embodiment of the present disclosure, in order to improve the utilization rate of the charging pile and the utilization rate of the charging pile 11, the street lamp 12 is communicatively connected to the charging pile 11, and the charging pile 11 detects whether it is in an unoccupied state, that is, whether it has electricity Devices (for example: electric cars, electric bicycles, smart terminals, etc.) are being charged through the charging pile, that is, whether the charging pile itself is supplying power to the electric equipment. If the charging pile 11 detects that it is in an unoccupied state, Then, a prompt message is generated, and the prompt message is sent to the street light 12.

The street light 12 can be any street light on the street. Since the street light is usually regularly distributed on both sides of the road, and electric vehicles often pass under the street light 12, the street light 12 can be used to detect whether the electric vehicle passing below issues a charging request. If the electric vehicle passing below the street light 12 issues a charging request, the street light 12 sends the position information of the charging pile in an unoccupied state to the electric vehicle, so that the electric vehicle can travel to the unoccupied charging pile, and then Charging takes place via an unoccupied charging station.

With the above technical solution, on the one hand, an electric vehicle can issue a charging request when there is a demand for charging, and when the electric vehicle passes under the street light, the charging request can be detected by the street light; on the other hand, the charging pile detects that it is not in use. In the occupied state, a prompt message is sent to the street light to find the electric vehicle that needs to be charged through the street light. In this way, the unoccupied charging pile is fully utilized and will not be in the unoccupied state for a long time. The information interaction between the electric vehicle with the charging demand and the charging pile in an unoccupied state is established through the street light, making full use of the location advantage of the street lamp located above the electric vehicle, which is convenient for monitoring the charging demand of the electric vehicle. In addition, when the charging pile is unoccupied, the prompt information is actively sent to the outside, which also increases the possibility that the charging pile is fully utilized.

Optionally, the street lamp 12 is a street lamp whose distance from the charging pile 11 is smaller than a preset distance.

In order to increase the possibility of the unoccupied charging pile 11 being used, when detecting that it is in an unoccupied state, the charging pile 11 sends prompt information to the street lamp 12 whose distance from it is less than a preset distance, where: The preset distance can be determined according to the utilization demand of the charging pile 11. If the utilization rate of the charging pile 11 needs to be increased, the preset distance can be set to a larger value.

Optionally, when the electric vehicle issues a charging request, the street lamp 12 determines each of the street lamps 12 that the electric vehicle passes through to reach the charging pile, and controls each of the street lamps 12 to light up.

In the embodiment of the present disclosure, the street light 12 may be any one of the street light 1-the street light N, and each of the street lights 1-the street light N is communicatively connected to the charging post 11, and can receive prompt information sent by the charging post 11, At the same time, a communication connection can be established between each two street lamps 12.

In order to facilitate the electric vehicle with charging demand to quickly reach the position of the unoccupied charging pile 11, the street lamp 12 can send the position information of the unoccupied charging pile 11 to the electric vehicle with charging demand, and can also determine the charging demand. The electric vehicle to each street lamp 12 passed by the unoccupied charging pile, and then sends a control instruction to each street lamp 12 to control the lighting of each street lamp 12, so that the user of the electric vehicle follows the guidance of each illuminated street lamp 12 Drive in the direction, you can reach the unoccupied charging pile 11, and then start charging.

Optionally, when the electric vehicle issues a charging request, in addition to sending the location information of the charging pile to the electric vehicle, the street light may also send the electric vehicle's charging request to the charging pile; accordingly According to the charging request of the electric vehicle, the charging pile 11 determines a charging mode matching the electric vehicle, and turns on the charging mode.

FIG. 2 is a schematic diagram of information interaction between a street lamp and a charging pile in an embodiment of the present disclosure. As shown in Figure 2, the information interaction includes the following steps:

Step S11: The charging pile detects whether it is in an unoccupied state, and when it detects that it is in an unoccupied state, it proceeds to step S12;

Step S12: sending prompt information to the street light, the prompt information indicates that the charging pile is in an unoccupied state;

Step S13: The street lamp detects whether the electric vehicle passing under itself has issued a charging request. When it detects that the vehicle passing under itself has issued a charging request, it proceeds to steps S14 and S15, and the execution order of steps S14 and S15 is not sequential, as shown in the figure. 2 Take step S14 as an example for execution before step S15;

Step S14: the street light sends the position information of the charging pile to the electric vehicle;

Step S15: the street lamp sends a charging request for the electric vehicle to the charging pile;

Step S16: According to the charging request of the electric vehicle, the charging pile determines a charging mode matching the electric vehicle, and turns on the determined charging mode.

After the charging pile 11 sends to the street lamp 12 the prompt message that it is in an unoccupied state, it can receive the charging request returned by the street lamp 12, and then determine a suitable charging mode according to the charging request, and turn on the charging mode.

For example, the charging pile 11 originally uses the charging mode A to charge the electric vehicle a. After the charging of the electric vehicle a is completed, the charging pile is in an unoccupied state, so a reminder message is sent to the street lamp 12, and the electric vehicle is passed below the street lamp 12. b. The street light 12 detects the charging request sent by the electric vehicle b. Therefore, the street light 12 forwards the charging request to the charging post 11 and the charging post 11 determines that the charging mode matching the electric vehicle b is the charging mode B according to the charging request. Turn on charging mode B. In this way, when the electric vehicle b reaches the charging pile 11, the charging pile 11 is ready to charge the electric vehicle b immediately.

With the above technical solution, when the electric vehicle that issues a charging request arrives at the charging pile, the charging pile is ready for charging, which saves the preparation time for charging and shortens the length of time the electric vehicle occupies the charging pile. On the one hand, it improves the charging efficiency. On the other hand, the utilization rate of the charging pile is improved.

Optionally, when the electric vehicle issues a charging request, in addition to sending the position information of the charging pile 11 to the electric vehicle, the street light 12 may also send the electric vehicle a charging request to the charging pile; Accordingly, the charging pile 11 determines a charging time for charging the electric vehicle according to the charging request of the electric vehicle, and sends the prompt information to the street lamp 12 when the charging time ends.

After the charging pile 11 sends to the street lamp 12 the prompt message that it is in an unoccupied state, it can receive the charging request returned by the street lamp 12, and then determine the charging time of the electric vehicle that issued the charging request according to the charging request. During the charging time, the electric energy is continuously output to the electric vehicle. At the end of the charging time, the charging pile returns to the unoccupied state by default, so it sends a prompt message to the street light indicating that it is in an unoccupied state.

For example, when the charging pile 11 detects that it is in an unoccupied state, it sends a prompt message to the street light 12. The electric vehicle c passes under the street light 12, and the street light 12 detects the charging request sent by the electric vehicle c. Therefore, the street light 12 sends The charging station 11 forwards the charging request. According to the charging request, the charging station 11 determines that the electric vehicle c is expected to arrive at the charging station at 18:00 and needs to be charged for 1 hour. Therefore, the charging station 11 charges the electric vehicle within 1 hour after 18:00. The vehicle c is charged, and the charging ends at 19:00, so a reminder message is sent to the street light 12 to indicate that the charging pile 11 is in an unoccupied state.

With the above technical solution, the charging pile automatically sends prompt information immediately after the charging of the electric vehicle is completed, in order to find other electric vehicles that require charging through street lights as soon as possible, and to minimize the length of time the charging pile is in an unoccupied state and improve The utilization rate of charging pile.

After the charging pile 11 sends the prompt information to the street lamp 12, it detects whether the charging start instruction sent by the electric vehicle is received within a preset period of time, that is, it checks whether the electric vehicle that issued the charging request arrives at the charging pile 11 within the preset period of time and requests The charging post 11 starts to charge it. If the electric vehicle that issued the charging request does not reach the charging post 11 within a preset time period, or if it reaches the charging post 11 within a preset time period but does not request the charging post 11 to start charging it, At this time, in order to improve the utilization rate of the charging pile, the charging pile 11 may send prompt information to the surrounding power terminals, so that other power terminals can be charged through the charging pile 11.

By adopting the above technical solution, a preset period of validity is retained for electric vehicles that require charging, and electric vehicles that require charging within the preset period of time issue a charging start command to perform charging. After the preset period of time has passed, the charging pile will pass to other Use the electric terminal to charge to improve the utilization rate of the charging pile and avoid the long duration of the charging pile being in an unoccupied state (for example, exceeding a preset time). The preset duration can be determined according to the utilization demand of the charging pile. If the utilization rate of the charging pile needs to be increased, the preset duration can be set to a smaller value.

Optionally, the street light 12 includes a light pole and a light fixture, and the light fixture is detachably connected to the light pole and adapted to the electric vehicle.

In the embodiment of the present disclosure, the street lamp 12 includes a light pole and a lamp, wherein the lamp can be dual-purpose, and can be used as a street lamp or a lamp of an electric vehicle. The lamp is detachably connected to the lamp post. When used as a street lamp, the lamp is fixed on the lamp post; when used as a lamp, the lamp can be removed from the lamp post and then installed on an electric vehicle. In this way, it is achieved that the electric lamp of the electric vehicle does not consume the electric power of the electric vehicle, that is, the power source of the electric vehicle lamp is independent of the entire vehicle electric power source of the electric vehicle. It improves the endurance of electric vehicles and also increases the practicality of street lights.

FIG. 3 is a flowchart of a charging method according to an embodiment of the present disclosure. As shown in FIG. 3, the charging method includes the following steps:

Step S31: receiving a charging request sent by a vehicle around the street light;

Step S32: detecting whether there is an idle charging pile in the communication range of the streetlight;

Step S33: When an idle charging pile within the communication range of the street lamp is detected, the position information of the idle charging pile is sent to the vehicle, so that the vehicle is charged through the idle charging pile.

In the embodiment of the present disclosure, the type of the idle charging pile is not limited, and any type of charging pile can be used as the idle charging pile in the embodiment of the present disclosure. In one embodiment, the idle charging pile is a wireless charging pile.

In the embodiment of the present disclosure, in order to improve the utilization rate of the charging pile, the street light is communicatively connected to the charging pile, and the street light detects whether each charging pile within its communication range is in an unoccupied state, that is, whether there is an electric device (for example, an electric vehicle) , Electric bicycles, smart terminals, etc.) are being charged through the charging pile, that is, whether the charging pile itself is supplying power to the electric equipment. If it is detected that the charging pile is in an unoccupied state, the charging pile is an idle charging pile. .

The street light can be any street light on the street. Because the street light is usually regularly distributed on both sides of the road, and there are often vehicles passing under the street light, it can receive the charging request from vehicles passing by under the street light. The vehicle sends a charging request (for example, the vehicle is in a low battery state), the street light sends the position information of the charging pile in an unoccupied state to the vehicle, so that the vehicle can drive to the unoccupied charging pile, and then Charging takes place via an unoccupied charging station.

With the above technical solution, on the one hand, the electric vehicle can issue a charging request when there is a charging demand. After the street lamp receives the charging request, it detects the idle charging pile and sends the position information of the idle charging pile to the vehicle. The location information can reach the idle charging pile, and then use the idle charging pile for charging. In this way, the unoccupied charging pile is fully utilized and will not be left unoccupied for a long time. The information interaction between a vehicle with a charging demand and a charging pile in an unoccupied state is established through a street light, which increases the possibility that the charging pile is fully utilized.

Optionally, the method further includes:

In the embodiment of the present disclosure, the street light may be any one of the street light 1 to the street light N, and each of the street lights 1 to the street light N is communicatively connected to a charging pile within a respective communication range, so as to detect an idle charging pile, A communication connection can also be established between the two street lights.

In order to make it easier for vehicles with charging needs to quickly reach the location of the unoccupied charging piles, street lights can send the location information of unoccupied charging piles to electric vehicles with charging needs, and can also determine the arrival of electric vehicles with charging needs. Each street lamp passed by the unoccupied charging pile, and then sends control instructions to each street lamp to control the lighting of each street lamp. In this way, the user of the electric vehicle can drive in the direction indicated by each lit street lamp to reach the Occupied charging pile, and then start charging.

Optionally, FIG. 4 is another flowchart of the charging method in the embodiment of the present disclosure. As shown in FIG. 4, the method further includes the following steps:

Step S34: when it is detected that there is no idle charging pile in the communication range of the streetlight, determine the reachable range of the vehicle according to the remaining power of the vehicle;

Step S35: Determine the idle charging pile in the reachable range by communicating with other street lights, and send the position information of the idle charging pile to the vehicle, so that the vehicle is charged through the idle charging pile.

In the embodiment of the present disclosure, it is considered that each charging post in the communication range of the street light is not an idle charging post, that is, each charging post in the communication range of the street light is externally powered and cannot charge the vehicle. Therefore, the vehicle needs to travel to other communication ranges of the street light. Idle charging pile. Therefore, when the street light detects that there is no idle charging pile within its own communication range, it first determines the reachable range of the vehicle according to the remaining power of the vehicle. Then, by communicating with other street lights, an idle charging pile within the reachable range of the vehicle is found, so that the vehicle is charged by the idle charging pile.

For example: if the vehicle's remaining power is sufficient to travel 20km, the reachable range of the vehicle is a circular area centered on the current position of the vehicle and a radius of 20km. Therefore, the street light communicates with the street lights in the center area, determines the idle charging piles in the center area, and then sends the position information of the idle charging piles (for example, driving 10km west from the current position of the vehicle) to the vehicle. The driver can drive to the position of the idle charging pile according to the position information, and then complete the charging.

Optionally, the method further includes:

After the street lamp sends the position information of the idle charging pile to the vehicle, it detects whether the charging start instruction sent by the electric vehicle is received within a preset period of time, that is, it checks whether the vehicle that issued the charging request arrives at the idle charging pile within the preset period of time, and Request an idle charging pile to start charging it, if the vehicle that sent the charging request did not arrive at the idle charging pile within a preset time period, or arrived at the idle charging pile within a preset time period but did not request the idle charging pile to start charging it At this time, in order to improve the utilization rate of the charging pile, the street light can send the position information of the idle charging pile to the power terminals around the idle charging pile, so that other power terminals can charge through the idle charging pile.

With the above technical solution, a preset period of validity is retained for vehicles that require charging, and electric vehicles that have a demand for charging within a preset period of time issue a charging start command to perform charging. After the preset period of time, the street lamp notifies other power terminals , So that the idle charging pile will charge other power terminals, so as to improve the utilization rate of the charging pile and prevent the charging pile from being left unoccupied for too long (for example, exceeding a preset duration). The preset duration can be determined according to the utilization demand of the charging pile. If the utilization rate of the charging pile needs to be increased, the preset duration can be set to a smaller value.

FIG. 5 is a schematic diagram of a street lamp according to an embodiment of the present disclosure. As shown in FIG. 5, the street lamp 12 provided in the embodiment of the present disclosure includes a light source 601, a heat dissipation component 602, a processor 603, and a memory 604.

The heat dissipating component 602 includes thermally conductive silicone grease. A processor 603, a memory 604, and a light source 601 are disposed above the heat dissipating component 602. The processor 603 is connected to the memory 604 and the light source 601, respectively. The memory 604 is configured to store computer program instructions for execution by the processor 603, and the computer program instructions are obtained according to the charging method described above. The processor 603 is configured to execute computer program instructions in the memory 604 to complete all or part of the steps of the charging method described above.

Since the processor 603, the memory 604, and the light source 601 are disposed above the heat dissipating component 602 in the street light 12, the other components in the street light 12 (for example, the processor 603, the memory 604, and the light source) can be better handled by the heat dissipating component 602 601) perform heat dissipation, as far as possible, ensure that the above-mentioned other components will not be overheated due to poor heat dissipation, and further ensure the intelligence of the streetlight 12 as much as possible.

Optionally, the thermally conductive silicone grease included in the heat dissipating component 602 is prepared from a specific composition including a silicone oil, a first filler, a second filler, and an optional auxiliary agent, based on 100 parts by weight of the silicone oil. The content of the first filler is 10 to 60 parts by weight, the content of the second filler is 50 to 150 parts by weight, and the content of the auxiliary agent is 0 to 20 parts by weight; the first filler includes metal thermal conductivity Material and phase change material, the weight ratio of the metal thermal conductor and the phase change material is 1: (0.2 ~ 2.5); the second filler includes carbon nanotubes and graphene, and the weight of the carbon nanotubes and graphene The ratio is 1: (1 ~ 20).

Preferably, based on 100 parts by weight of the silicone oil, the content of the first filler is 20 to 40 parts by weight, the content of the second filler is 80 to 120 parts by weight, and the content of the auxiliary agent is 0. ~ 10 parts by weight;

Further preferably, in order to further increase the thermal conductivity of the thermally conductive silicone grease and reduce the thermal resistance value, R calculated by the following formula may be 6.5-35.5:

R = 0.656w (second filler) -1.581w (first filler) + 0.11w (auxiliary agent),

Wherein, w (first filler) represents parts by weight of the first filler with respect to 100 parts by weight of silicone oil,

w (second filler) means parts by weight of the second filler with respect to 100 parts by weight of silicone oil,

w (auxiliary agent) means the weight part of the auxiliary agent with respect to 100 weight part of silicone oils.

The thermally conductive silicone grease composition uses a metal thermally conductive material and a phase change material as the first filler. Compared with the traditional thermally conductive silicone grease using only a metal thermally conductive material as a filler, the thermally conductive silicone grease composition can effectively improve the heat absorption rate of the heat source, and has rapid heat absorption, The effect of heat transfer; the simultaneous use of carbon nanotubes and graphene as the second filler not only greatly improves the thermal conductivity, but also facilitates compatibility with silicone oil, further improving the quality and performance of the specific composition described above.

The thermally conductive silicone grease prepared from the above composition can effectively improve the thermal conductivity and heat dissipation efficiency of the heat dissipation component 602. Due to the improved heat dissipation efficiency, a smaller volume of the heat dissipation component 602 can achieve a good heat dissipation effect, which can save more space for the placement of the light source 601, the processor 603, the memory 604, and other components, and reduce the street light. 12 overall volume.
