[0002] New energy vehicles refer to vehicles that use unconventional vehicle fuels as their power source (or use conventional vehicle fuels and new vehicle power devices), and integrate advanced technologies in vehicle power control and drive to form vehicles with advanced technical principles, new technologies, and new structures. New energy vehicles include pure electric vehicles, extended-range electric vehicles, hybrid vehicles, etc.

[0003] Most new energy vehicles use electricity as power, which can reduce automobile exhaust emissions and even achieve zero exhaust emissions and zero pollution. New energy vehicles that use electricity as power generally supply energy to the battery by charging, and the battery is easily affected by temperature when charging. When the battery of a new energy vehicle is charging, the temperature of the battery is low, and the conductivity of the positive electrode, negative electrode, electrolyte, etc. of the new energy vehicle battery will decrease, resulting in the precipitation of substances inside the battery, resulting in a decrease in the conductivity of the new energy vehicle battery, which seriously affects the battery life. A high temperature environment may cause the battery temperature to be too high, which may easily lead to an increase in the rate of chemical reactions in the battery and an increase in the rate of reactant consumption, thereby causing the battery performance to decrease, the efficiency to decrease, and affecting the battery life.

[0042] In order to enable those skilled in the art to better understand the technical solutions in the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0043] like Figures 1 to 12As shown, a new energy vehicle charging station in one embodiment of the present invention includes a charging area 1 and a waiting area 2, both of which are used to park new energy vehicles. The charging area 1 is used to park new energy vehicles that are being charged, and the waiting area 2 is used to store new energy vehicles waiting to be charged. A plurality of marking lines 7 are provided on the charging area 1 and the waiting area 2. The size of the marking line 7 is the same as the size of the parking space, and can adapt to most new energy vehicles. The new energy vehicles are parked in the marking line 7. Of course, the size of the marking line 7 can also be changed as needed to adapt to new energy vehicles of different sizes and types.

[0044] like Figure 1 to Figure 3 As shown, a plurality of charging piles 101 are installed on the charging area 1, and the charging piles 101 are used to charge new energy vehicles. The charging pile 101 includes a shell 1011 and a charging element 1012 installed inside the shell 1011, and the shell 1011 is used to protect the charging element 1012. In order to solve the problem that the charging element 1012 will heat up during the use of the charging area 1, and the charging element 1012 needs to be cooled so that the charging area 1 can be within the preferred operating temperature range, the new energy vehicle charging station includes a circulating heat exchange component and a temperature compensation circulation pipeline 12, and the circulating heat exchange component can compensate for the temperature of the charging pile 101, and can also store the heat generated by the charging pile 101.

[0045] Specifically, Figure 1 to Figure 7 As shown, the circulating heat exchange component includes a liquid storage component 4 and a circulating heat exchange pipeline 5. The liquid storage component 4 is used to store heat exchange medium, and the circulating heat exchange pipeline 5 is used to circulate heat exchange medium. Through the cooperation of the liquid storage component 4 and the circulating heat exchange pipeline 5, the heat generated by the charging pile 101 is circulated, thereby reducing the temperature of the charging pile 101.

[0046] like Figure 1 to Figure 7 As shown, a temperature compensation component 6 is provided in the identification line 7, and the temperature compensation component 6 can contact the battery of the new energy vehicle and realize the heat exchange of the battery of the new energy vehicle. Specifically, the temperature compensation circulation pipeline 12 can output the heat stored in the circulation component to the temperature compensation component 6, so that the temperature compensation component 6 can increase the heat of the battery of the new energy vehicle and realize the utilization of heat. The temperature compensation component 6 cooperates with the temperature compensation circulation pipeline 12 to compensate for the temperature of the battery of the new energy vehicle, and can also store the heat generated by the battery of the new energy vehicle and utilize it.

[0047] like Figure 1 to Figure 6As shown, the liquid storage assembly 4 includes a first box 401 and a second box 402, and a first connecting pipe 404 is connected between the first box 401 and the second box 402. The volume of the second box 402 is smaller than that of the first box 401, and the second box 402 is used to store a relatively cold heat exchange medium, and the first box 401 is used to store a relatively hot heat exchange medium. The first box 401 and the second box 402 are connected through the first connecting pipe 404. According to the communicating vessel principle, when the heat exchange medium in the second box 402 is output, the first box 401 can replenish the corresponding amount of heat exchange medium in the second box 402, so that the heat exchange medium stock in the second box 402 will not decrease.

[0048] In general, the first box 401 is a box with good heat preservation effect, and the second box 402 is a box with good heat dissipation effect. The temperature of the heat exchange medium in the first box 401 is higher than the temperature of the heat exchange medium in the second box 402. The heat exchange medium in the second box 402 is used for circulating cooling. The heat exchange medium in the first box 401 waits to enter the second box 402 and exchange heat after cooling. The heat exchange medium stored in the first box 401 has high heat, and hot steam will be generated inside. The upper end of the first box 401 is provided with an exhaust port 4011, and the hot steam is output through the exhaust port 4011. By connecting the hot gas output pipeline, the hot gas after heat exchange is transported to other places for use. In general, a waiting room will be set up in a new energy vehicle charging station, and drivers and passengers can wait in the waiting room for charging to be completed while waiting for charging.

[0049] When the liquid storage assembly 4 is used in a cold environment such as winter, the hot air is transported to the waiting room through the hot air output pipe to increase the temperature in the waiting room. The hot air is processed and transported to the vehicle through the hot air output pipe to increase the temperature in the vehicle. When the new energy vehicle is waiting to be charged, the new energy vehicle does not need to consume electricity and can maintain a high temperature, which greatly improves the comfort of the new energy vehicle when waiting to be charged in a cold environment, reduces the energy consumption of the new energy vehicle when waiting to be charged, and shortens the charging time of the new energy vehicle.

[0050] When the liquid storage component 4 is used in a high temperature environment such as in summer, heat is transported to the water heating and insulation equipment in the waiting room through the first box body 401, thereby achieving preheating or insulation during water transportation and reducing energy consumption of equipment in the waiting room.

[0051] Preferably, in order to ensure that the cold heat exchange medium circulating through the circulating heat exchange pipeline 5 can meet the heat exchange requirements each time, a heat dissipation component matching the second box 402 can be provided. The heat dissipation component can be a heat dissipation fin, a refrigerant, etc. The heat dissipation component dissipates heat for the heat exchange medium in the second box 402. Its volume is smaller, which can greatly improve the heat dissipation effect and also reduce the energy consumption required for heat dissipation. The heat exchange medium in the first box 401 and the second box 402 are not connected to each other, that is, the cold heat exchange medium in the second box 402 is not easy to affect the temperature of the heat exchange medium in the first box 401.

[0052] Preferably, in order to avoid the situation where the heat exchange medium vaporizes during use and the heat exchange medium becomes less and less with the use time, a liquid level detection component can be set in the first box body 401, and a liquid adding component matching the liquid level detection component can be set. When the liquid level is at the threshold, the liquid adding component adds liquid to the first box body 401.

[0053] like Figure 1 to Figure 7 As shown, the circulating heat exchange pipeline 5 includes a heat exchange tube 501, which is installed between the housing 1011 and the charging element 1012, and can also be installed inside the housing 1011. The separate installation of the heat exchange tube 501 and the housing 1011 facilitates reducing the cost during maintenance. The heat exchange tube 501 is arranged outside the charging element 1012, and a heat exchange medium flows in the heat exchange tube 501. The heat exchange medium can absorb heat and cool down the charging element 1012, thereby reducing the heat generated by the charging pile 101 during use. Avoid high temperature of the charging pile 101, thereby avoiding fires caused by high temperature of the charging pile 101.

[0054] Specifically, the circulating heat exchange pipeline 5 also includes a cold liquid pipe 502 and a hot liquid pipe 504. The hot liquid pipe 504 is installed on the first box 401 and communicates with the first box 401, and the cold liquid pipe 502 is installed on the second box 402 and communicates with the second box 402. A third connecting pipe 505 is connected between the output end of the heat exchange pipe 501 and the hot liquid pipe 504, and a second connecting pipe 503 is connected between the output end of the heat exchange pipe 501 and the cold liquid pipe 502. The second box 402, the cold liquid pipe 502, the heat exchange pipe 501, the hot liquid pipe 504, and the first box 401 form a cycle, which can complete the circulation of the heat exchange medium and realize the cooling of the charging pile 101 at the same time.

[0055] like Figure 1 to Figure 7As shown, a fourth connecting pipe 506 is installed between the hot liquid pipe 504 and the second connecting pipe 503, and the hot heat exchange medium in the hot liquid pipe 504 can be transported to the second connecting pipe 503 through the fourth connecting pipe 506. When the temperature of the charging pile 101 is lower than the optimal operating temperature range, the hot heat exchange medium in the hot liquid pipe 504 is transported to the corresponding heat exchange pipe 501 to increase the temperature inside the charging pile 101, so that the charging pile 101 can quickly reach the optimal operating temperature, avoiding the situation where the charging pile 101 works in a low temperature environment for a long time and affects the charging efficiency of the charging pile 101, and avoiding the situation where the low temperature operation of the charging pile 101 affects the service life of the charging pile 101.

[0056] like Figure 1 to Figure 7 As shown, a pump 403 is installed between the first box 401 and the cold liquid pipe 502, and the pump 403 provides power for the circulation of the heat exchange medium. A twelfth connecting pipe 508 is connected between the first box 401 and the pump 403. That is, the heat exchange medium is pumped into the first box 401 through the pump 403. A temperature detection component 3 is installed on the twelfth connecting pipe 508, and the temperature detection component 3 is used to detect the temperature of the heat exchange medium in the twelfth connecting pipe 508. A fifth connecting pipe 507 is installed between the twelfth connecting pipe 508 and the second box 402. The temperature of the heat exchange medium is detected by the temperature detection component 3 and it is determined whether to be transported to the first box 401 or the second box 402.

[0057] like Figure 1 to Figure 7 As shown, the temperature of the heat exchange medium in the first box 401 is higher than the temperature of the heat exchange medium in the second box 402. If the temperature detection component 3 detects that the temperature of the heat exchange medium in the twelfth connecting pipe 508 is lower than the temperature of the heat exchange medium in the first box 401, the heat exchange medium is transported to the second box 402. Otherwise, the heat exchange medium is transported to the first box 401. Specifically, a solenoid valve is provided on the first connecting pipe 404, and the remaining amount of the heat exchange medium in the second box 402 is controlled by the solenoid valve. Generally, the heat exchange medium in the second box 402 will not exceed 1 / 4 of the volume of the second box 402, which is convenient for the colder heat exchange medium to enter. The colder heat exchange medium does not enter the first box 401, and will not affect the temperature of the heat exchange medium in the first box 401, so that the heat in the first box 401 can be fully utilized.

[0058] like Figure 1 to Figure 7 As shown, a hot liquid extension tube 5041 is provided at one end of the hot liquid pipe 504 away from the liquid storage component 4, and a cold liquid extension tube 5021 is provided at one end of the cold liquid pipe 502 away from the liquid storage component 4. The cold liquid extension tube 5021 is used to transport the cold heat exchange medium to the temperature compensation component 6, and the hot liquid extension tube 5041 is used to transport the heat exchange medium after heat exchange back to the liquid storage component 4.

[0059] like Figures 1 to 12As shown, the temperature compensation component 6 is composed of one or more temperature compensation units 601. The temperature compensation unit 601 includes a liquid storage shell 6011, a heat exchange part 6012 integrally formed with the liquid storage shell 6011, and a telescopic rod 6013. A groove 701 matching the identification line 7 is provided on the charging area 1 and the waiting area 2. One end of the telescopic rod 6013 is installed at the lower end of the liquid storage shell 6011, and the other end is installed on the bottom wall of the groove 701. The heat exchange part 6012 is arranged at the upper end of the liquid storage shell 6011, and the liquid storage shell 6011 and the heat exchange part 6012 form a sealed cavity, and the heat exchange medium can flow in the cavity. The upper end surface of the temperature compensation component 6 is lower than the surface of the identification line 7, that is, the temperature compensation component 6 will not affect parking when not in use. When the temperature compensation component 6 needs to be used, the liquid storage shell 6011 and the heat exchange part 6012 are pushed out by the telescopic rod 6013, so that the heat exchange part 6012 can contact the battery pack of the new energy vehicle.

[0060] Specifically, Figures 1 to 12 As shown, the lower end of the temperature compensation unit 601 is installed with a sixth connecting pipe 602 and an eighth connecting pipe 603, a seventh connecting pipe 6021 is installed between the sixth connecting pipe 602 and the temperature compensation unit 601, and a ninth connecting pipe 6031 is installed between the eighth connecting pipe 603 and the temperature compensation unit 601. The sixth connecting pipe 602 is used to transport cold heat exchange medium, and the eighth connecting pipe 603 is used to transport hot heat exchange medium. The cold liquid extension pipe 5021 is connected to the sixth connecting pipe 602, and the hot liquid extension pipe 5041 is connected to the eighth connecting pipe 603. The cold liquid extension pipe 5021, the sixth connecting pipe 602, the temperature compensation unit 601, the eighth connecting pipe 603 and the hot liquid extension pipe 5041 form a cooling pipeline. The cold liquid extension pipe 5021 transports the cold heat exchange medium to the sixth connecting pipe 602, and the sixth connecting pipe 602 transports the heat exchange medium to the temperature compensation unit 601. The heat exchange medium after heat exchange is transported to the eighth connecting pipe 603, and then the eighth connecting pipe 603 transports the heat exchange medium to the hot liquid extension pipe 5041, and the hot liquid extension pipe 5041 transports the heat exchange medium to the liquid storage component 4. The cooling operation of the new energy vehicle battery is completed.

[0061] In the initial state, the cavity formed by the temperature compensation unit 601 and the sixth connecting pipe 602 contains a heat exchange medium, that is, heat exchange can be performed the moment the temperature compensation component 6 and the new energy vehicle battery come into contact, which can improve the cooling efficiency of the new energy vehicle battery.

[0062] like Figures 1 to 12As shown, the new energy vehicle charging station includes a temperature compensation circulation pipeline 12 matched with the liquid storage component 4, and the temperature compensation circulation pipeline 12 includes a thirteenth connecting pipe 1201 and a fourteenth connecting pipe 1202. The thirteenth connecting pipe 1201 is installed on the second box body 402, and the fourteenth connecting pipe 1202 is installed on the first box body 401. The thirteenth connecting pipe 1201 is connected to the sixth connecting pipe 602, the fourteenth connecting pipe 1202 is connected to the eighth connecting pipe 603, and the fourteenth connecting pipe 1202, the eighth connecting pipe 603, the temperature compensation unit 601, the sixth connecting pipe 602 and the thirteenth connecting pipe 1201 form a temperature increase pipeline, which can transport the hot heat exchange medium to the temperature compensation unit 601. When the battery temperature of the new energy vehicle is low, the hot heat exchange medium is used to exchange heat with the battery to increase the temperature of the battery. In the process of waiting for heat exchange, the battery can be heated, and the battery heating time is reduced during charging, thereby improving the charging speed of the new energy vehicle. Reduce the waiting time for the subsequent new energy vehicle. Greatly improve the charging speed of a single new energy vehicle, thereby improving the overall charging speed of new energy vehicle charging stations, improving the charging efficiency of new energy vehicle charging stations, and at the same time facilitating the increase of new energy vehicle charging station revenue.

[0063] In the initial state, the cavity formed by the temperature compensation unit 601 and the sixth connecting pipe 602 contains a heat exchange medium, and the temperature of the heat exchange medium is equal to the ambient temperature. When the sixth connecting pipe 602 contacts the battery of the new energy vehicle, the hot heat exchange medium is transported to the cavity through the heating pipeline. When the hot heat exchange medium is transported, it is generally transported slowly to the cavity, so that the temperature in the cavity increases slowly, avoiding the situation where the initial temperature of the temperature compensation component 6 is too high and causes damage to the battery of the new energy vehicle.

[0064] like Fig.10 As shown, the heat exchange medium can push out the heat exchange part 6012, so that the upper end surface of the heat exchange part 6012 is an arc surface. When the heat exchange part 6012 contacts the battery of the new energy vehicle, the telescopic rod 6013 can continue to apply pressure to increase the contact force between the heat exchange part 6012 and the battery of the new energy vehicle, thereby increasing the pressure of the heat exchange part 6012 on the battery of the new energy vehicle, thereby improving the heat exchange efficiency.

[0065] The temperature compensation component 6 is provided with a temperature detection component (not shown in the figure). When the temperature compensation component 6 contacts the battery of the new energy vehicle, the temperature of the battery of the new energy vehicle can be detected. Through the contact temperature detection method, the temperature detection effect is more accurate. The temperature compensation component 6 can determine the temperature compensation method of the temperature compensation component 6 according to the result of the temperature detection component detection, that is, determine whether to perform hot compensation or cold compensation according to the result of the temperature detection component detection.

[0066] The new energy vehicle charging pile also includes a visual detection component, which determines the location of the new energy vehicle battery through visual detection, and cooperates with the temperature compensation component 6 to perform temperature compensation on the battery. Specifically, the visual detection component generally determines the model of the new energy vehicle first, and lifts the temperature compensation component 6 at the corresponding position according to the model of the new energy vehicle to contact the battery of the new energy vehicle. If the model of the new energy vehicle does not exist, the position of the battery pack is determined according to the chassis structure of the new energy vehicle, and further confirmation and trimming are carried out by the staff to ensure that the temperature compensation component 6 is aligned with the battery of the new energy vehicle to complete the thermal compensation operation of the battery pack. For new models of new energy vehicles, after the position of the battery is determined, the visual detection component stores this data for easy use next time.

[0067] When the new energy vehicle charging station is in use, the new energy vehicle is first parked in the marking line 7 on the charging area 1, and the position of the new energy vehicle battery is determined according to the visual detection component. After the position of the battery is confirmed, the telescopic rod 6013 corresponding to the battery is started to make the heat exchange part 6012 contact with the new energy vehicle battery. After contact, the temperature of the new energy vehicle battery is detected by the temperature detection component, and it is determined whether the new energy vehicle battery needs to be cooled or heated according to the temperature. If the new energy vehicle battery needs to be cooled, after the new energy vehicle battery and the temperature compensation component 6 exchange heat, the second box 402 transports the cold heat exchange medium to the cold liquid pipe 502, and the heat exchange medium is transported to the cold liquid extension pipe 5021, and then transported to the sixth connecting pipe 602 by the cold liquid extension pipe 5021, and finally transported to the liquid storage shell 6011, and the original hot heat exchange medium is discharged, and the cold heat exchange medium is located in the liquid storage shell 6011 to continue to exchange heat. The hot heat exchange medium is transported to the pump 403 through the eighth connecting pipe 603, the hot liquid extension pipe 5041, and the hot liquid pipe 504, and the temperature of the hot heat exchange medium in the pump 403 is determined by the temperature detection component 3, and according to the detection result of the temperature detection component 3, it is determined whether the heat exchange medium in the first box 401 is higher than the temperature of the heat exchange medium detected by the temperature detection component 3. If the temperature detected by the temperature detection component 3 is higher than the temperature of the heat exchange medium in the first box 401, the heat exchange medium is transported to the first box 401 through the twelfth connecting pipe 508, otherwise, the heat exchange medium is transported to the second box 402 through the fifth connecting pipe 507. This prevents the low temperature heat exchange medium from lowering the temperature of the heat exchange medium in the first box 401.

[0068] If the battery of the new energy vehicle needs to be heated up, the high-temperature heat exchange medium is transported to the fourteenth connecting pipe 1202 through the first box 401, and then transported to the eighth connecting pipe 603 by the fourteenth connecting pipe 1202. The hot heat exchange medium is slowly transported to the temperature compensation unit 601 by the eighth connecting pipe 603, and the battery of the new energy vehicle is slowly heated up. The heat exchange medium after heat exchange is output to the thirteenth connecting pipe 1201 through the sixth connecting pipe 602, and then the thirteenth connecting pipe 1201 transports the cooled heat exchange medium to the second box 402.

[0069] When the temperature of the new energy vehicle battery rises, it can be heated up through slow charging of the charging pile 101, and at the same time, the temperature compensation component 6 can be used to physically heat the battery to accelerate the heating speed of the new energy vehicle battery, so that the new energy vehicle battery can reach the fast charging temperature, thereby reducing the charging speed of the new energy vehicle battery, improving the charging efficiency of the new energy vehicle battery, and reducing the time the owner waits for charging. At the same time, the time that a single new energy vehicle in the new energy vehicle charging station occupies the charging pile 101 is increased, thereby improving the charging efficiency of the new energy vehicle charging station and improving the benefits of the new energy vehicle charging station.

[0070] When the charging pile 101 needs to be thermally compensated, the hot heat exchange medium is transported to the third connecting pipe 505 through the cooperation of the first box body 401 and the hot liquid pipe 504, and then the third connecting pipe 505 and the fourth connecting pipe 506 cooperate to transport the hot heat exchange medium to the corresponding charging pile 101, so that the charging pile 101 can quickly reach the optimal working temperature.

[0071] like Figure 1 to Figure 15 As shown, a safety protection device of a new energy vehicle charging station in one embodiment of the present invention includes a second nozzle 9, which is arranged along the identification line 7. The second nozzle 9 sprays a heat exchange medium along the outer wall of the new energy vehicle, which can extinguish the fire of the new energy vehicle and form a fire extinguishing protection layer on the outside of the new energy vehicle. When the new energy vehicle is charging at the new energy vehicle charging station, the damage to other new energy vehicles due to the spontaneous combustion of the new energy vehicle is reduced.

[0072] like Figure 13-14 As shown, the safety protection device includes a first nozzle 60111, which is arranged at the upper end, and a tenth connecting pipe 10 is installed between the first nozzle 60111 and the hot liquid extension pipe 5041. That is, the first nozzle 60111 can also spray out the heat exchange medium to extinguish the fire from the lower end of the new energy electric vehicle. The first nozzles 60111 at different positions have different spraying directions, and the fire extinguishing effect is greatly improved through multi-directional spraying.

[0073] like Figure 13 to Figure 15As shown, the safety protection device also includes a third box 8, which is arranged at the bottom of the charging area 1. The third box 8 stores a reaction medium. The reaction medium and the heat exchange medium are combined to obtain a fire extinguishing medium. The fire extinguishing performance of the fire extinguishing medium is better than that of the reaction medium and the heat exchange medium. When the fire is not big, the fire extinguishing operation is completed only by the heat exchange medium. When the fire is big, the reaction medium and the heat exchange medium are combined to achieve the fire extinguishing operation.

[0074] Specifically, the eleventh connecting pipe 11 is installed on the third housing 8, and a liquid dispensing pipe 1101 is installed between the eleventh connecting pipe 11 and the first nozzle 60111. The extension lines of the tenth connecting pipe 10 and the liquid dispensing pipe 1101 intersect, and the reaction medium and the heat exchange medium sprayed from the liquid dispensing pipe 1101 and the tenth connecting pipe 10 can collide and combine before being sprayed from the first nozzle 60111, and then sprayed from the first nozzle 60111 after being combined.

[0075] Among them, the heat exchange medium can be a fluid with heat exchange effect such as water. If the heat exchange medium is water, the reaction medium can be a salt enhancer, such as potassium carbonate, potassium bicarbonate, sodium carbonate, sodium bicarbonate, etc. The reaction medium can greatly improve the fire extinguishing performance of the heat exchange medium.

[0076] The new energy vehicle charging station in the present invention can dissipate heat for the charging pile 101, and by collecting the heat generated by the charging pile 101, the heat output is used to heat the battery of the new energy vehicle, accelerate the heating speed of the battery of the new energy vehicle, make the battery of the new energy vehicle quickly reach the optimal charging temperature, quickly enter the fast charging state, reduce the charging time of the battery of the new energy vehicle, improve the battery charging efficiency of the new energy vehicle, and increase the upper limit of the number of charging vehicles of the new energy vehicle charging station. At the same time, the heat generated by the battery of the new energy vehicle during the charging process can be recovered and collected to avoid the high temperature of the battery of the new energy vehicle during the charging process, which is beneficial to increase the service life of the battery of the new energy vehicle. The collected heat can also be used to heat the batteries of other new energy vehicles, reducing the energy consumption of heating the batteries of the new energy vehicles.

[0077] The present invention can achieve temperature compensation for the battery of the new energy vehicle during the charging process of the new energy vehicle by arranging the temperature compensation component 6 on the charging area 1. The present invention can achieve temperature compensation for the battery of the new energy vehicle while the new energy vehicle is waiting for charging by arranging the temperature compensation component 6 on the waiting area 2. The temperature compensation component 6 can enable the new energy vehicle to quickly enter the charging state, thereby reducing the time consumed for charging the new energy vehicle.

[0078] The safety protection device of the new energy vehicle charging station in the present invention can provide protection for new energy vehicles after they catch fire. It can reduce the damage caused to other vehicles by new energy vehicle fires during charging, reduce the losses caused by new energy vehicles catching fire at new energy vehicle charging stations, improve the safety of new energy vehicles at new energy vehicle charging stations, and at the same time improve the competitiveness of new energy vehicle charging stations.
