Description

Technical Field

[0001] This utility model relates to the field of charging equipment technology, and in particular to a charging stack with a backup control system. Background Technology

[0002] A charging pile is a large-scale power cluster that can meet large-scale charging needs, such as in large parking lots or enterprises. A charging pile is equipped with multiple charging terminals that can serve multiple electric vehicles simultaneously. Compared with individual charging piles, this improves charging conversion efficiency and equipment utilization.

[0003] However, during the process of using a charging pile to charge an electric vehicle, there may be situations where charging is interrupted. A sudden interruption of charging not only requires the user to wait for the charging pile to restore power, but the sudden interruption may also trigger the electric vehicle's battery management system (BMS), causing the electric vehicle's battery to enter protection mode, preventing the electric vehicle from continuing to charge for a short period of time, thereby further extending the user's electric vehicle charging time.

[0004] Therefore, how to reduce the occurrence of charging interruptions during the charging process, so as to avoid the problem of significantly extended charging time for electric vehicles due to charging interruptions, has become a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] The purpose of this invention is to provide a charging pile with a backup control system to reduce the occurrence of charging interruptions during the charging process, thereby avoiding the problem of significantly extended charging time for electric vehicles due to charging pile interruptions.

[0006] To achieve the above objectives, this utility model provides the following solution:

[0007] This utility model provides a charging pile with a backup control system, the charging pile comprising:

[0008] A first power supply assembly and a second power supply assembly, both storing electrical energy, wherein the first power supply assembly includes a first housing and a power supply body disposed within the first housing; when the charging pile is in a first power supply state, the first output port of the first power supply assembly is connected to the input port of the charging terminal; when the charging pile is in a second charging state, the second output port of the second power supply assembly is connected to the input port of the charging terminal.

[0009] The heat dissipation assembly includes an insulation layer disposed between the first housing and the power supply body, the insulation layer being filled with a phase change heat storage material, the phase change temperature of the phase change heat storage material being lower than the lowest temperature within the rated operating temperature range of the first power supply assembly.

[0010] Preferably, the insulation layer has a plurality of independently arranged first cavities evenly distributed within it, and the first cavities are filled with the phase change heat storage material.

[0012] Preferably, the heat dissipation assembly includes a fan and an air duct disposed on the first housing, the fan being disposed at the inlet and / or outlet of the air duct, and the air duct being connected to the outside and the interior of the first housing, respectively.

[0013] Preferably, the outlet is provided with a filter and a baffle from the inside out. One end of the baffle is rotatably connected to the outlet. The baffle can block the outlet. When the fan is started, the baffle rotates under the airflow generated by the fan, releasing the blockage of the outlet.

[0014] Preferably, the charging pile includes a second housing, the second housing having a first switching component, a first terminal connected to the first power component, and a second terminal connected to the second power component, the first terminal and the second terminal being disposed opposite to each other;

[0015] The first switching component includes:

[0016] A first wire, the first end of the first wire is located between the first terminal and the second terminal, the second end of the first wire is connected to the input port, and a magnetic layer is sleeved on the first wire between its two ends.

[0017] A first electromagnet is located on the side of the first conductor near the first terminal, and the first electromagnet is connected to the first power supply assembly. When the charging pile is in the first power supply state, the first electromagnet applies a first force to the first conductor, and the first force causes the first end of the first conductor to abut against the first terminal. The first force is directed from the first conductor toward the first terminal.

[0018] A first reset element is located on the side of the first conductor near the second terminal. The first reset element applies a second force to the first conductor. The second force is directed from the first conductor toward the second terminal and is less than the first force. When the charging pile is in the second charging state, the second force causes the first end of the first conductor to abut against the second terminal.

[0019] Preferably, the first wire is connected to the second housing, the extension line of the connection point between the first wire and the second housing is perpendicular to the plane where the first terminal is located, and the connection point between the first wire and the second housing is located between the magnetic layer and the second end of the first wire.

[0020] Preferably, the first conductor is provided with a reinforcing layer to improve its strength;

[0021] The charging stack includes an operating rod, the first end of which extends into the second housing and is rotatably connected to the second housing, and the area on the first wire located between the magnetic layer and the second end of the first wire is fixedly connected to the operating rod.

[0022] An indicator rod is provided in the area outside the second housing of the operating lever, the indicator rod extending radially along the operating lever, and a first power supply mark and a second power supply mark are provided around the operating lever on the outer side of the second housing;

[0023] When the indicator rod points to the first power supply mark, the first end of the first wire abuts against the first terminal block; when the indicator rod points to the second power supply mark, the first end of the first wire abuts against the second terminal block.

[0025] And / or, the charging pile further includes a first detection element connected to the first power supply assembly, the first detection element being used to reflect the operating status of the first power supply assembly; or, a filter is provided between the first power supply assembly and the first terminal block.

[0026] Preferably, the first power supply component is connected to a power supply component, which includes mains power, and / or a generator, and / or a solar power generation unit.

[0027] The present invention achieves the following technical advantages over the prior art:

[0028] The charging pile of this invention includes a first power supply component and a second power supply component that store electrical energy. Both the first and second power supply components can supply power to the charging terminal. When the charging pile is in a first power supply state (which can be understood as the state in which the first power supply component can supply power to the charging terminal), the first output port of the first power supply component is connected to the input port of the charging terminal, and the first power supply component supplies power to the charging terminal. When the charging pile is in a second power supply state (which can be understood as the state in which the first power supply component cannot supply power to the charging terminal), the second output port of the second power supply component is connected to the input port of the charging terminal, and the second power supply component charges the charging terminal. Thus, the second power supply component is equivalent to a backup power source for the charging pile. Normally, the first power supply component provides power to the charging terminal. When the first power supply component cannot provide power to the charging terminal, the second power supply component provides power to the charging terminal, thereby reducing the occurrence of charging interruptions during the use of the charging pile and thus reducing the problem of extended charging time for electric vehicles due to interruptions during the use of the charging pile.

[0029] Furthermore, the first power supply component in this invention includes a first housing and a power supply body within the first housing. The heat dissipation component includes an insulation layer disposed between the first housing and the power supply body, and the insulation layer is filled with a phase change heat storage material. The phase change temperature of the phase change heat storage material is lower than the lowest temperature within the rated operating temperature range of the first power supply component. This means that when the first power supply component starts working, the phase change heat storage material absorbs the heat generated by the power supply body through phase change heat storage. This reduces the risk of the first power supply component failing to supply power normally due to overheating. At the same time, because the phase change temperature of the phase change heat storage material is lower than the lowest temperature within the rated operating temperature range of the first power supply component, the temperature inside the first housing is not lower than the lowest temperature within the rated operating temperature range of the first power supply component under normal operating conditions. This prevents the heat stored in the phase change heat storage material from being actively dissipated into the first housing. Thus, the insulation layer achieves effective heat dissipation for the first power supply component. This not only reduces the problem of the first power supply component failing and being damaged due to overheating, thus reducing the heat loss of the first power supply component, enabling the first power supply component to maintain a high power output, thereby further shortening the charging time of electric vehicles.

Detailed Implementation

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0035] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0036] like Figures 1-2 As shown, this utility model discloses a charging pile with a backup control system. The charging pile includes: a first power supply component and a second power supply component, which store electrical energy. The first power supply component includes a first housing 1 and a power supply body 2 disposed within the first housing 1. The first and second power supply components can supply power to a charging terminal. When the charging pile is in a first power supply state, the first output port of the first power supply component is connected to the input port of the charging terminal. When the charging pile is in a second charging state, the second output port of the second power supply component is connected to the input port of the charging terminal. A heat dissipation component includes a heat insulation layer 3 disposed between the first housing 1 and the power supply body 2. The heat insulation layer 3 is filled with a phase change heat storage material, and the phase change temperature of the phase change heat storage material is lower than the lowest temperature within the rated operating temperature range of the first power supply component.

[0037] The charging pile of this invention includes a first power supply component and a second power supply component that store electrical energy. Both the first and second power supply components can supply power to the charging terminal. When the charging pile is in a first power supply state (which can be understood as the state in which the first power supply component can supply power to the charging terminal), the first output port of the first power supply component is connected to the input port of the charging terminal, and the first power supply component supplies power to the charging terminal. When the charging pile is in a second power supply state (which can be understood as the state in which the first power supply component cannot supply power to the charging terminal), the second output port of the second power supply component is connected to the input port of the charging terminal, and the second power supply component charges the charging terminal. Thus, the second power supply component is equivalent to a backup power source for the charging pile. Normally, the first power supply component provides power to the charging terminal. When the first power supply component cannot provide power to the charging terminal, the second power supply component provides power to the charging terminal, thereby reducing the occurrence of charging interruptions during the use of the charging pile and thus reducing the problem of extended charging time for electric vehicles due to interruptions during the use of the charging pile.

[0038] Furthermore, the first power supply component in this invention includes a first housing 1 and a power supply body 2 within the first housing 1. The heat dissipation component includes a heat insulation layer 3 disposed between the first housing 1 and the power supply body 2. The heat insulation layer 3 is filled with a phase change heat storage material. The phase change temperature of the phase change heat storage material is lower than the lowest temperature within the rated operating temperature range of the first power supply component. This means that when the first power supply component starts working, the phase change heat storage material absorbs the heat generated by the power supply body through phase change heat storage. This reduces the risk of the first power supply component failing to supply power normally due to overheating. Simultaneously, because the phase change temperature of the phase change heat storage material is lower than the lowest temperature within the rated operating temperature range of the first power supply component... The lowest temperature within the rated operating temperature range of the first power component is ensured. Therefore, under normal operating conditions, the temperature inside the first housing 1 is not lower than the lowest temperature within the rated operating temperature range of the first power component. This prevents the heat stored in the phase change heat storage material from being actively dissipated into the first housing 1. Thus, the insulation layer 3 effectively dissipates heat from the first power component. This not only reduces the problem of the first power component failing or being damaged due to overheating and interrupting power supply, but also reduces the heat loss of the first power component, enabling the first power component to maintain a high power output, thereby further shortening the charging time of the electric vehicle.

[0039] In this article, the "backup control system" in "charging stack with backup control system" refers to the first power supply component and the second power supply component. "Backup" means that the second power supply component is equivalent to a backup of the first power supply component. When the first power supply component fails and cannot supply power to the charging terminal, the second power supply component supplies power to the charging terminal. "Backup control" means that the power supply to the charging terminal is controlled through the cooperation of the first power supply component and the second power supply component.

[0040] The charging pile in this invention includes a control cabinet and several charging terminals connected to the control cabinet. Each charging terminal can be understood as a charging module or a charging pile. The charging terminal is used to output power from the first power supply component, the second power supply component, or the power grid to the electric vehicle via a charging gun or other charging equipment. The control cabinet and the charging terminals are connected via communication cables.

[0041] The first and second power supply components have the same structure; the terms "first" and "second" are used only for ease of differentiation. Depending on the operating conditions, the first and second power supply components can be installed inside or outside the control cabinet. Specifically, the first and second power supply components may include structures such as batteries that store and output electrical energy. The first power supply component can be understood as a structure with a battery inside the first housing 1, and the power supply body can be understood as the battery. The first output port and second output port refer to the power output ports of the first and second power supply components, respectively, while the charging terminal input port refers to the power input port of the charging terminal. The rated operating temperature refers to the temperature reached by the first power supply component under normal operating conditions (e.g., operating at rated power).

[0042] The phase change heat storage material can be a hydrated salt, molten salt, metal, or alloy. Regardless of the type of phase change heat storage material, its phase change temperature must be lower than the lowest temperature within the rated operating temperature range of the first power supply component. The insulation layer 3 can be an insulation board with an internal cavity. The insulation board has a feeding hole communicating with the cavity. After adding the required amount of phase change heat storage material into the cavity through the feeding hole, the feeding hole is sealed by welding or other methods to prevent the phase change heat storage material from overflowing. Even after adding the required amount of phase change heat storage material into the cavity, some space remains within the cavity for the phase change of the heat storage material.

[0043] In this invention, the insulation layer 3 can contain more than one cavity, such as several first cavities 4, or only one cavity, such as only one second cavity. When only one second cavity is provided in the insulation layer 3, the second cavity needs to occupy a larger area of ​​the insulation layer 3 to ensure that the insulation layer 3 has a large heat absorption area to absorb the heat dissipated by the power supply body 2. Compared with multiple first cavities 4, the steps of filling the cavity with phase change heat storage material and sealing the cavity are simpler. It should be noted that both the first cavity 4 and the second cavity are used to fill the phase change heat storage material, and both the first cavity 4 and the second cavity are provided with filling holes for adding the phase change heat storage material. After adding the required amount of phase change heat storage material, the filling holes are sealed to prevent the phase change heat storage material in the insulation layer 3 from leaking during use.

[0044] like Figure 1As shown, when several independently arranged first cavities 4 are evenly distributed within the insulation layer 3, compared to the second cavity, the first cavity 4 makes the insulation layer 3 more sensitive to temperature changes in the first power supply component: when the temperature in a local area within the first cavity 4 is high, the phase change heat storage material in the corresponding area of ​​the first cavity 4 can quickly absorb heat and undergo a phase change, thereby promptly reducing the temperature inside the first shell 1. However, if only one second cavity is arranged within the insulation layer 3, due to the larger capacity and heat capacity of the phase change heat storage material in the second cavity, its reaction speed is slower. Compared to the first cavity 4, the second cavity will only undergo a phase change when the temperature inside the first shell 1 rises to a higher temperature, thus reducing the temperature inside the first shell 1. The independent arrangement of several first cavities 4 means that any two first cavities 4 are not interconnected.

[0045] Furthermore, the heat dissipation component includes liquid-cooled pipes that pass through the first housing 1. Both the inlet and outlet of the liquid-cooled pipes are connected to a storage tank containing the cooling medium. A circulation pump is installed on the liquid-cooled pipes. The circulation pump drives the cooling medium to flow within the liquid-cooled pipes, effectively removing excess heat generated within the first housing 1 and the insulation layer 3, preventing heat accumulation within the first housing 1. The liquid-cooled pipes are in contact with the power supply unit 2 and / or the insulation layer 3; alternatively, they may not be in contact with the insulation layer 3 or the power supply unit 2, but only with the air inside the first housing 1. The cooling medium can be water, air, liquid nitrogen, or any other medium capable of absorbing and removing heat. The storage tank needs to be equipped with equipment capable of cooling the medium, such as a compression refrigeration unit; if the storage tank is a cooling tower, additional refrigeration equipment can be omitted.

[0046] Furthermore, to reduce heat accumulation inside the first shell 1, liquid cooling pipes can be installed on the insulation layer 3. The liquid cooling pipes and the first cavity 4 are arranged to avoid interference (the arrangement of the two means that their structures and functions do not interfere with each other), and the liquid cooling pipes are in close contact with the first cavity 4. At this time, when the phase change heat storage material in the first cavity 4 absorbs heat from the first shell 1, the liquid cooling pipes carry the heat absorbed by the phase change heat storage material to the outside, thereby further preventing heat accumulation inside the first shell 1.

[0047] Alternatively, the heat dissipation assembly includes a fan 5 and an air duct mounted on the first housing 1. The fan 5 is located at the inlet and / or outlet of the air duct (the outlet refers to the opening of the air duct near the outside and connected to the outside; the inlet refers to the air duct itself). The air duct is connected to both the outside and the interior of the first housing 1. The fan 5 is connected to a power supply device, which can be understood as mains power (mains power refers to the power provided by the city power grid). By activating the fan 5, the heat generated inside the first housing 1 is promptly exhausted to the outside through the air duct, preventing heat accumulation inside the first housing 1. The air duct refers to the channel opened within the first housing 1 for airflow. The air duct can be set horizontally, vertically, or inclined along the first housing 1, as long as it can exhaust the heat inside the first housing 1 to the outside. The outside refers to the ambient air. Similarly, if required by the operating conditions, the air duct can also be mounted on the insulation layer 3, fitting snugly against the first cavity 4.

[0048] Furthermore, such as Figure 1 As shown, a filter screen 6 and a baffle 8 are sequentially arranged from the inside to the outside at the outlet of the air duct. One end of the baffle 8 is rotatably connected to the outlet. Figure 1 As shown, the rotational connection point between the baffle 8 and the outlet is the first rotational connection point 9. The baffle 8 can block the outlet. When the fan 5 is started, the baffle 8 rotates under the action of the airflow generated by the fan 5, releasing the blockage of the outlet. The filter screen 6 can trap external impurities, reducing the amount of dust entering the first housing 1. The area of ​​baffle 8 is slightly smaller than the area of ​​the outlet to ensure that baffle 8 can be smoothly installed at the outlet. However, the area of ​​baffle 8 is large enough that when fan 5 is not running, baffle 8 can seal the outlet under its own weight to prevent external dust from entering. Baffle 8 can rotate outward under the action of airflow. When fan 5 is not running, the other end of baffle 8 abuts against the outlet under its own weight. Alternatively, a stepped structure can be provided on the side of baffle 8 near the interior of the first housing 1, i.e., a ring of protrusions 7 is provided around the circumference of the outlet. The protrusions 7 extend in the direction close to the center line of the outlet. In this case, after the protrusions 7 are provided, the area of ​​the outlet at the protrusions 7 is smaller than the area of ​​baffle 8. When fan 5 is not running, baffle 8 covers the protrusions 7 under its own weight, thereby sealing the outlet. The outlet can be set in the horizontal or vertical direction of the first housing 1.

[0049] like Figure 2As shown, the charging pile includes a second housing 10, within which a first switching assembly is provided, a first terminal 14 connected to a first power supply assembly, and a second terminal 15 connected to a second power supply assembly. The first terminal 14 and the second terminal 15 are arranged opposite to each other. The first switching assembly includes: a first wire 12, the first end of which is located between the first terminal 14 and the second terminal 15, and the second end of which is connected to an input port. A magnetic layer 13 is sleeved on the first wire 12, located between its two ends. The magnetic layer 13 is a structural layer that can move towards the first electromagnet 11 and the first terminal 14 under the magnetic attraction of the first electromagnet 11. The magnetic layer 13 can be made of materials such as ferromagnetic metal. A first electromagnet 11 is located on the side of the first wire 12 near the first terminal 14. The first electromagnet 11 is connected to the first power supply assembly and can be positioned close to the first terminal 14. When the charging pile is in a first power supply state, the first electromagnet 11 applies a first force to the first wire 12. The force is applied from the first wire 12 toward the first terminal 14. Because the first force is greater than the second force, the first force can cause the first end of the first wire 12 to move or rotate toward the first terminal 14 (because the first wire 12 has a certain degree of flexibility, the first end of the first wire 12 can move toward the first terminal 14 under the first force when the second end of the first wire 12 is connected to the input port, i.e., the input port of the charging terminal), until it abuts against the first terminal 14; the first reset member 16 is located on the side of the first wire 12 near the second terminal 15. The first reset member 16 applies a second force to the first wire 12. The second force is applied from the first wire 12 toward the second terminal 15 and is less than the first force; when the charging pile is in the second charging state, because the first power supply component cannot continue to supply power, the first electromagnet 11 loses its magnetism and cannot apply the first force to the first wire 12. The second force causes the first end of the first wire 12 to move toward the second terminal 15 until it abuts against the second terminal 15.

[0050] In short, the structure described above allows the first power supply component to quickly switch to the second power supply component when it is unable to supply power to the charging terminal. The second power supply component then supplies power to the charging terminal. This shortens the time that the charging pile is interrupted due to insufficient power from the first power supply component and reduces the problem that the charging pile only has the first power supply component, and that the charging is interrupted due to a long wait for repair after the first power supply component fails.

[0051] The first wire 12 is connected to the second housing 10. The extension line of the connection point between the first wire 12 and the second housing 10 is perpendicular to the plane where the first terminal 14 is located. The connection point between the first wire 12 and the second housing 10 is located between the magnetic layer 13 and the second end of the first wire 12. By rotating or fixing the first wire 12 and the second housing 10, the first wire 12 is limited, so that the first end of the first wire 12 can rotate towards the first terminal 14 under a first force. When the first wire 12 and the second housing 10 are rotated, the rotation connection point between the first wire 12 and the second housing 10 is the second rotation connection point 17.

[0052] The first conductor 12 is provided with a reinforcing layer to improve its strength. This reinforcing layer can be a carbon fiber layer or a polyurethane fiber layer. The charging stack includes an operating lever. The first end of the operating lever extends into the second housing 10 and is rotatably connected to it. The area on the first conductor 12 between the magnetic layer 13 and the second end of the first conductor 12 is fixedly connected to the first end of the operating lever. An indicator rod is provided on the area outside the second housing 10 of the operating lever. The indicator rod extends radially along the operating lever. A first power supply mark and a second power supply mark are provided circumferentially around the operating lever outside the second housing 10. When the indicator rod points to the first power supply mark, the first end of the first conductor 12 abuts against the first terminal 14. When the indicator rod points to the second power supply mark, the first end of the first conductor 12 abuts against the second terminal 15. When the first switching component fails, the operator can switch between the first power supply component and the second power supply component by rotating the operating lever, allowing the second power supply component to supply power to the charging terminal when the first power supply component fails.

[0053] The charging pile includes a second switching component, which includes a second wire and a third wire. The two ends of the second wire are connected to a first power supply component and an input port, respectively. A first switch is provided on the second wire to control its on / off state. The two ends of the third wire are connected to the second power supply component and an input port, respectively. A second switch is provided on the third wire to control its on / off state. The first and second switches allow the operator to manually switch between the first and second power supply components when the first switching component malfunctions, shortening the charging pile's power outage time. Alternatively, the charging pile also includes a first detection element connected to the first power supply component. The first detection element reflects the operating status of the first power supply component. Specifically, the first detection element may be a voltage detector or other structure that reflects whether the first power supply component is outputting power. Alternatively, a filter is provided between the first power supply component and the first terminal block 14 to reduce electromagnetic interference.

[0054] The first power supply component is connected to a power supply unit, which includes mains power, and / or a generator, and / or a solar power generation unit. The solar power generation unit is a device that absorbs solar energy, converts it into electrical energy, and supplies it to the first power supply component. The solar power generation unit is existing technology, and its specific structure will not be described in detail. By supplying power to the first power supply component through the power supply unit, the first power supply component can output power more continuously and stably, thereby reducing the problem of power interruption during electric vehicle charging due to the depletion of power within the first power supply component.
