Description
Technical Field
[0001] This invention relates to the field of charging pile technology, and more specifically to a high-power charging pile based on an energy storage system. Background Technology
[0002] High-power charging piles based on energy storage systems are intelligent charging devices that integrate energy storage units (such as lithium battery packs) and high-power charging modules. By storing electricity during off-peak hours / when photovoltaic power is abundant, and releasing it during peak hours / when vehicles are charging, they can achieve peak shaving and valley filling, alleviate grid expansion pressure, improve charging efficiency, shorten charging time, adapt to the rapid charging needs of new energy vehicles, and have both grid support and flexible charging and discharging capabilities.
[0003] When traditional high-power charging piles are used in low-temperature environments such as nighttime and extreme cold, the performance of their energy storage batteries will significantly decrease. Low temperatures increase the viscosity of the battery electrolyte, significantly slow down the migration rate of lithium ions between the positive and negative electrodes, reduce the electrochemical reaction rate of the electrode active materials, and significantly increase the battery's internal resistance. This results in a reduction in the battery's effective usable capacity and a decrease in charging and discharging efficiency, making it difficult to continuously output the high current required for high-power charging. On the other hand, the charging voltage window of the battery narrows at low temperatures, and the system will actively limit the charging power to protect the battery. In severe cases, it may even directly trigger the low-temperature protection strategy, preventing the charging pile from starting normally or causing unexpected interruptions during charging. This not only significantly extends the waiting time for a single charge but also directly weakens the actual usability of the charging pile in winter or high-altitude areas. Summary of the Invention

[0014] Beneficial effects The technical solution provided by this invention has the following advantages compared with the known prior art: I. This invention, by setting up components such as a heat recovery and insulation mechanism, utilizes the cooperative relationship between the components to absorb and store the redundant heat generated during the charging process in the phase change block; and in a low-temperature environment, the flow regulation component releases the stored heat in the reverse direction into the cooling pipe to heat the heat exchange medium, thereby achieving uniform heat preservation of the battery pack and the charging pile body, effectively solving the problems of battery performance degradation and limited charging power in low-temperature environments, and ensuring stable high-power output of the charging pile in frigid environments.
[0015] Second, this invention, by setting up components such as flow regulation components, utilizes shape memory alloy strips to sense changes in medium temperature and generate adaptive deformation, which drives the sealing block to adjust the flow cross-sectional area of the cooling pipe. At the same time, the slider touches the micro switch to control the three-way valve to switch the medium flow path, and drives the mechanical speed regulator to adjust the output power of the drive source, thereby achieving dual coordinated regulation of medium flow rate and velocity.

[0020] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.
[0021] The present invention will be further described below with reference to embodiments.
[0022] See attached document Figure 1-10 A high-power charging pile based on an energy storage system includes: a charging pile body 1, a battery pack fixedly connected inside the charging pile body 1, and the battery pack electrically connected to the charging pile body 1 via wires; a charging plug electrically connected to the charging pile body 1 via wires; and further includes: The heat recovery and insulation mechanism 2 for thermal storage and circulation includes a drive source, which is fixedly connected to the interior of the charging pile body 1. A transmission rod 201 is fixedly connected to the output end of the drive source, and a ratchet 202 is fixedly connected to the other end of the transmission rod 201. A water pump 203 is installed at the other end of the ratchet 202, and the power input end of the water pump 203 is elastically connected to the ratchet 202 via a pawl. The water outlet end of the water pump 203 is connected to a cooling pipe 204 via a one-way valve, and the cooling pipe 204 is wound around a heat spreader plate on the battery pack. A flow channel is provided inside the cooling pipe 204. The regulating component 205, the other end of the cooling pipe 204 is connected to the heat conduction pipe 206, and the heat conduction pipe 206 is stacked. A one-way heat conduction plate 207 is fixedly connected to the outside of the heat conduction pipe 206. A heat storage box 208 is fixedly connected to the outside of the one-way heat conduction plate 207. A phase change block is provided inside the heat storage box 208. A suction moving component 209 is provided on one side of the heat conduction pipe 206. The other end of the heat conduction pipe 206 is connected to the water storage tank 210 through a three-way valve. The water storage tank 210 is connected to the suction end of the water pump 203. A movable heat dissipation component 211 is provided on one side of the heat storage box 208. The drive source provides stable power for the entire mechanism, driving the transmission rod 201 to rotate synchronously. The transmission rod 201 drives the ratchet 202 to rotate synchronously, and the ratchet 202 drives the water pump 203 to operate stably through the pawl, realizing the closed-loop circulation and transportation of the heat exchange medium. The water pump 203 draws the heat exchange medium from the water storage tank 210 and delivers it to the cooling pipe 204 through a one-way valve. The cooling pipe 204 is tightly wrapped around the heat spreader plate of the charging pile body 1, which can fully absorb the redundant heat generated by the charging pile body 1 and the battery pack during high-power operation, realizing precise cooling and protection of the core electrical components, and effectively preventing the core components from experiencing performance degradation or damage due to continuous high temperature. To address the issue of shortened lifespan, the heat exchange medium carrying heat flows through the cooling pipe 204 into the stacked heat conduction pipes 206. A unidirectional heat conduction plate 207 conducts the heat carried by the heat exchange medium in the heat conduction pipes 206 unidirectionally to the heat storage box 208. The phase change block in the heat storage box 208 efficiently absorbs and stably stores heat, achieving efficient recovery and reuse of waste heat during charging, significantly reducing energy consumption. The flow regulation component 205 adaptively adjusts the flow state and rate of the heat exchange medium according to its real-time temperature in the cooling pipes 204, precisely adapting to heat exchange requirements under different operating conditions, improving the adaptability of the equipment under all operating conditions. Stability; the three-way valve can flexibly switch the flow path of the heat exchange medium according to the operating conditions. The suction movable component 209 can cooperate with the switching of the medium flow path to achieve precise temperature control of the charging pile plug socket, effectively avoiding problems such as poor contact and charging failure caused by high temperature aging or low temperature frost on the plug socket; the movable heat dissipation component 211 can automatically start heat dissipation when the temperature inside the heat storage box 208 exceeds the safety threshold, quickly releasing the excess heat inside the heat storage box 208, avoiding the failure and damage of the heat storage box 208 and phase change block due to overheating, and ensuring the long-term stable operation of the heat storage system; in low-temperature environments such as severe cold at night, the flow regulating component 205 can... The heat stored in the heat storage box 208 is conducted in reverse to the cooling pipe 204, heating the heat exchange medium inside the pipe. The heated heat exchange medium provides continuous and stable heat preservation for the battery pack and the charging pile body 1. The suction and movement component 209 can work with the flow adjustment component 205 to achieve temperature balance of the medium in the cooling pipe 204 and the heat conduction pipe 206, effectively solving the problems of reduced effective capacity, decreased charging and discharging efficiency, limited charging power, and even failure of equipment to start normally caused by increased electrolyte viscosity, slowed lithium ion migration rate, and increased internal resistance in the battery pack under low temperature environment, thus fully ensuring the stable high-power output of the charging pile in low temperature environment. See attached document Figure 2-6The flow regulating component 205 includes a shape memory alloy strip 2051, which is fixedly connected to the charging pile body 1. A sealing block 2052 is fixedly connected to one end of the shape memory alloy strip 2051, and the sealing block 2052 is slidably connected to the cooling pipe 204. A slider 2053 is fixedly connected to the other end of the shape memory alloy strip 2051, and the slider 2053 is slidably connected to the charging pile body 1. A micro switch 2054 is provided on one side of the slider 2053. The micro switch 2054 is prior art and is fixedly connected to the charging pile body 1. The micro switch 2054 is also connected to a three-way valve via a wire. Electrically connected, a mechanical speed regulating plate 2055 is provided on one side of the slider 2053. The mechanical speed regulating plate 2055 is existing technology and is fixedly connected to the charging pile body 1. The adjustment end of the mechanical speed regulating plate 2055 is fixedly connected to the slider 2053. The mechanical speed regulating plate 2055 is electrically connected to the drive source through a wire. A heat-conducting rod 2056 is fixedly connected to the other end of the slider 2053. A heat-absorbing net 2057 is provided on the top of the heat-conducting rod 2056. The heat-absorbing net 2057 is slidably connected to the inside of the heat storage box 208 and is elastically connected to the heat storage box 208 through a tension spring. The shape memory alloy strip 2051 can accurately sense the real-time temperature of the heat exchange medium inside the cooling pipe 204 and adapt its deformation to temperature changes. Simultaneously, it drives the sealing block 2052, which is fixedly connected to it, to slide smoothly inside the cooling pipe 204. Through this sliding motion, the effective flow cross-sectional area inside the cooling pipe 204 is flexibly adjusted, thereby precisely controlling the flow velocity of the heat exchange medium within the pipe. This achieves fully automatic adaptive adjustment of heat exchange efficiency according to operating conditions, without the need for an additional electronic control unit. This significantly improves the response speed and operational reliability of the adjustment action, effectively avoiding the problems of response lag, complex structure, and susceptibility to failure inherent in traditional electronic control adjustments. Simultaneously, the shape memory alloy strip 2051 deforms, driving the slider 2053, fixedly connected to its end, to move along a pre-defined path. Assuming a smooth sliding path, when slider 2053 slides to the preset trigger position, it can precisely activate microswitch 2054 to complete the action triggering. Microswitch 2054 can synchronously control the on / off switching state of the three-way valve, realizing precise switching of the heat exchange medium flow path, ensuring the adaptability of the medium circulation path under different operating conditions, and avoiding energy loss and temperature control deviation caused by ineffective medium flow. During the sliding process of slider 2053, it can simultaneously drive the adjustment end of mechanical speed regulator 2055 to complete the linkage action. Mechanical speed regulator 2055 can precisely adjust the output power of the drive source according to the displacement of slider 2053, thereby correspondingly adjusting the operating speed of water pump 203. This forms a precise coordination with the adjustment action of sealing block 2052 on the flow cross-sectional area, achieving... The dual coordinated regulation of medium flow rate and velocity, and when the mechanical speed regulator 2055 is adjusted to the preset critical position with the slider 2053, the drive source can be automatically started to complete the reverse action. In the reverse state of the drive source, the pawl transmission structure between the ratchet 202 and the water pump 203 is disconnected from the power transmission, and the water pump 203 can no longer be driven to complete the medium conveying action. Thus, the output driving force of the drive source is concentrated and transmitted to the suction moving component 209 to complete the corresponding action, which fully adapts to the medium circulation regulation requirements under different temperature environments and operating conditions, and improves the power utilization efficiency and operating condition adaptability of the entire mechanism. During the sliding process of the slider 2053, the heat-conducting rod 2056 fixedly connected to it can be driven to complete the synchronous displacement, and the heat-absorbing net 20 in the heat storage box 208 can be driven to complete the synchronous displacement. 57 can quickly absorb the heat pre-stored in the phase change block. When the heat-conducting rod 2056 moves with the slider 2053 to the position where it makes effective contact with the cooling pipe 204, the heat absorbed by the heat-absorbing net 2057 can be quickly and stably transferred to the heat exchange medium in the cooling pipe 204 through the heat-conducting rod 2056, realizing the rapid conduction and precise release of stored heat, effectively ensuring the heating efficiency of the heat exchange medium in low-temperature environments. The tension spring set in conjunction with the heat-absorbing net 2057 can drive the heat-absorbing net 2057 to smoothly complete the reset action when the slider 2053 resets, ensuring the stability of the action of the heat-absorbing net 2057 and the accuracy of the reset position throughout the process, avoiding the problem of reduced heat conduction efficiency and insufficient heat storage utilization caused by the position deviation of the heat-absorbing net 2057. Among them, a heat-absorbing block 3 is fixedly connected to the side of the shape memory alloy strip 2051 near the sealing block 2052, and a heat-insulating column 4 is slidably connected to the outside of the heat-conducting rod 2056. The heat-insulating column 4 is fixedly connected to the cooling pipe 204, and a heat-insulating ring 5 is rotatably connected inside the heat-insulating column 4 through a torsion spring. The heat-absorbing block 3 is fixedly installed on the side of the shape memory alloy strip 2051 near the sealing block 2052, which can quickly and efficiently absorb the real-time heat of the heat exchange medium in the cooling pipe 204 and uniformly and stably conduct the heat to the shape memory alloy strip 2051, greatly improving the response speed of the shape memory alloy strip 2051 to the temperature change of the medium, and effectively solving the problem of shape memory alloy strip 2051 temperature change. To address the issue of delayed adjustment actions caused by temperature sensing lag in the shape memory alloy strip 2051, this system ensures the timeliness and accuracy of the entire adjustment process, guaranteeing the synchronicity and reliability of adaptive heat exchange efficiency adjustment. The heat insulation column 4, fitted outside the heat-conducting rod 2056 and fixedly connected to the cooling pipe 204, effectively prevents the random and irregular conduction of heat on the heat-conducting rod 2056, avoiding ineffective heat loss from the heat storage box 208 during non-working periods. This precisely ensures the controllability and directionality of heat release within the heat storage box 208, significantly improving the effective utilization rate of heat. The heat insulation column 4 is rotated via a torsion spring. The internal heat insulation ring 5 can adaptively rotate and close by relying on the elastic force of the torsion spring, effectively isolating the heat exchange at both ends of the heat insulation column 4, further improving the overall heat insulation effect, avoiding energy loss caused by ineffective heat loss, and comprehensively improving the energy utilization efficiency of the entire device. When the heat conduction rod 2056 moves to the preset trigger position under the action of the slider 2053, it can directly push the heat insulation ring 5 to overcome the elastic force of the torsion spring and rotate, so that the heat insulation ring 5 releases the heat insulation closed state, opens the heat conduction path between the heat conduction rod 2056 and the cooling pipe 204, and ensures that the stored heat can be quickly and stably transferred to the heat exchange medium under low temperature conditions. In order to achieve precise and efficient heat preservation and heating, it is worth noting that the heat-conducting rod 2056 itself can slide and extend; one end of it is fixed to the slider 2053, and the other end is held in place by the heat-insulating and heat-absorbing block 8; when the heat-absorbing net 2057 moves, it will move the heat-insulating and heat-absorbing block 8 together, and the heat-insulating and heat-absorbing block 8 will pull this end of the heat-conducting rod 2056 to move along with it; however, because the heat-conducting rod 2056 itself can slide and extend, the end fixed to the slider 2053 will not move; in this way, the heat-conducting rod 2056 can transfer heat with the heat-absorbing net without affecting the stability of its fixation to the slider 2053. See attached document Figure 2-8The suction assembly 209 includes a flow tube 2091, which is connected to the other end of a three-way valve. The flow tube 2091 is also wound around the plug socket of the charging pile body 1. The other end of the flow tube 2091 is connected to a suction column 2092 via a one-way regulating valve. The suction column 2092 is fixedly connected to the interior of the water storage tank 210. The one-way regulating valve is electrically connected to a micro switch 2054. A one-way drain valve 2093 is connected to one side of the suction column 2092. The one-way drain valve 2093 is prior art, and the one-way drain valve 2093 is connected to the micro switch 2054. The switch 2054 is electrically connected. A suction ring 2094 is slidably connected inside the suction column 2092. An eccentric wheel 2095 is hinged to one side of the suction ring 2094 via a connecting rod. The connecting rod is elastically connected to the suction column 2092 via a flexible sealing ring. When the connecting rod moves, the flexible sealing ring deforms and fits against the surface of the connecting rod, leaving space for the movement of the connecting rod, thereby ensuring the operational stability of the connection. A driven bevel gear 2096 is fixedly connected to the bottom of the eccentric wheel 2095, and the driven bevel gear 2096 is connected to the transmission rod 201 via a transmission bevel gear. When the transmission rod 201 rotates, it can stably drive the driven bevel gear 2096 to rotate synchronously through the transmission bevel gear. The driven bevel gear 2096 synchronously drives the eccentric wheel 2095 to complete coaxial rotation. The eccentric wheel 2095 drives the suction ring 2094 to slide smoothly back and forth inside the suction column 2092 through the hinged connecting rod, accurately realizing the negative pressure suction and positive pressure discharge inside the suction column 2092. This provides stable power support for the directional flow and circulation control of the heat exchange medium, eliminating the need for an additional independent drive unit, greatly simplifying the device structure and improving the overall power utilization efficiency. Under high-temperature conditions during high-speed charging, the one-way drain valve 2093 remains initially open, and the one-way regulating valve maintains its one-way conduction function. The heat exchange medium can flow through the three-way valve into the flow pipe 2091 tightly wound on the plug socket of the charging pile body 1, fully absorbing the redundant heat generated when the plug socket is operating at high current, achieving efficient cooling and protection of the plug socket, and effectively avoiding the problems of insulation aging, increased contact resistance, or even burning damage to the plug socket due to continuous high temperature. After heat exchange, the cooling medium can flow through the one-way regulating valve into the suction column 2092, and then smoothly drain into the water storage tank 210 through the one-way drain valve 2093. Inside, a complete heat exchange cycle is completed. When the ambient temperature is too low, triggering the microswitch 2054, the microswitch 2054 can simultaneously control the three-way valve to close the main flow path of the heat exchange medium to the water storage tank 210, and simultaneously control the one-way drain valve 2093 to close and the one-way regulating valve to release its one-way conduction function. Together with the shape memory alloy strip 2051 deforming at low temperature, the sealing block 2052 completes the sealing action, thus achieving partial sealing of the internal space of the cooling pipe 204, heat conduction pipe 206, and flow pipe 2091 around the battery pack and plug socket, preventing the ineffective heat dissipation caused by the heat exchange medium flowing to the non-insulated area. When the heat exchange medium in the sealed space is lost, the reciprocating sliding motion of the suction ring 2094 can continuously draw the heat exchange medium in the sealed space and discharge it back into the flow pipe 2091, driving the cooling medium in the local sealed space to continuously circulate and flow, so that the medium temperature in all parts of the sealed space remains uniform and consistent, avoiding the occurrence of local low temperature areas, effectively providing all-round uniform heat preservation and heating for the battery pack and plug socket, solving the problems of plug socket frost, poor contact, charging interruption, and increased electrolyte viscosity and decreased charging and discharging efficiency in low temperature environments, and fully ensuring the stable operation and high-power continuous output capability of the charging pile in severe cold environments; The suction ring 2094 has a push rod 6 fixedly connected to its top, and the push rod 6 is fixedly connected to the heat absorption mesh 2057. An electromagnetic block 7 is fixedly connected to one side of the push rod 6. The electromagnetic block 7 is existing technology and is electrically connected to the micro switch 2054. A heat-insulating and heat-absorbing clip 8 is magnetically connected to one side of the electromagnetic block 7. The heat-insulating and heat-absorbing clip 8 is plugged into the heat absorption mesh 2057 and the heat-conducting rod 2056, and the heat-insulating and heat-absorbing clip 8 and the electromagnetic block 7 are elastically connected through a reset telescopic column. When the suction ring 2094 reciprocates within the suction column 2092, it synchronously drives the push rod 6 fixedly connected to its top to complete synchronous reciprocating movement. The push rod 6 synchronously drives the... The side-mounted electromagnetic block 7 completes the linkage action. Under the initial high-temperature condition of normal charging operation, the push rod 6 can work in conjunction with the non-energized electromagnetic block 7 and the heat-absorbing block 8 to drive the heat-absorbing mesh 2057 to move stably up and down inside the heat storage box 208, continuously disturbing the phase change block inside the heat storage box 208. This allows the phase change block to absorb the heat conducted by the heat pipe 206 in all directions and evenly, effectively solving the problems of local heat absorption saturation of the phase change block, insufficient phase change leading to decreased heat storage efficiency, and insufficient overall heat storage capacity. This significantly improves the heat storage uniformity and overall heat storage capacity of the phase change block. When the ambient temperature is too low and triggers the micro switch 2054, The micro switch 2054 can synchronously and precisely control the on / off state of the electromagnetic block 7. When the electromagnetic block 7 is energized, it generates a stable magnetic force, which drives the magnetically connected heat-absorbing card block 8 to overcome the elasticity of the reset telescopic column and complete directional movement. This releases the heat-absorbing card block 8 from the heat-absorbing mesh 2057, allowing the heat-absorbing mesh 2057 to form a stable and efficient heat conduction path with the heat-conducting rod 2056. This quickly and stably transfers the heat stored in the phase change block to the heat-conducting rod 2056, achieving rapid and efficient heat conduction and release. Simultaneously, the push rod 6 can synchronously push the heat-absorbing mesh 2057 to complete directional reciprocating movement within the heat storage box 208, continuously contacting different areas of the phase change block. This effectively avoids the solidification phenomenon of the phase change block in a fixed position after continuous heat absorption, and solves the problem of sudden drop in heat conduction efficiency and discontinuous heat transfer caused by solidified phase change blocks. The reciprocating movement of the heat absorption net 2057 further improves the stability and continuous heat conduction effect. When the electromagnetic block 7 is de-energized, the reset telescopic column can stably release the elastic force to drive the heat insulation and heat absorption block 8 to return to its original position, so that the heat insulation and heat absorption block 8 can re-enter and limit the heat absorption net 2057, restore the synchronous linkage state of the heat absorption net 2057 and the push rod 6, ensure the accurate switching of the heat absorption net 2057's operation mode under different working conditions, and improve the controllability and operational reliability of the device's heat storage and release throughout the process. The core of this invention lies in the fact that the flow regulating component 205 not only regulates the flow rate of the medium in the cooling pipe 204, but also serves as a linkage control center that senses temperature changes and triggers multiple protective actions. Specifically, the flow regulating component 205 includes a shape memory alloy strip 2051; one end of this shape memory alloy strip 2051 is slidably connected to the cooling pipe 204 via a sealing block 2052, and the other end is connected to a micro switch 2054 and a mechanical speed regulator 2055 via a slider 2053; the slider 2053 is also connected to a movable heat-absorbing mesh 2057 inside the heat storage box 208 via a heat-conducting rod 2056. Connection; When the charging pile is in a low-temperature environment, the temperature of the medium inside the cooling pipe 204 decreases; the shape memory alloy strip 2051 senses this temperature change and contracts; this contraction action triggers three chain reactions simultaneously: Regulating flow: The shape memory alloy strip 2051 pulls the sealing block 2052, reducing the flow cross-sectional area of the cooling pipe 204, slowing down the medium flow speed, and reducing heat loss during circulation; Switching path and adjusting power: The shape memory alloy strip 2051 pulls the slider 2053, which in turn triggers the micro switch 2054. The micro switch 2054 controls the three-way valve to switch the medium flow path, circulating the medium... The ring is confined within a sealed space around the battery; simultaneously, slider 2053 drives mechanical speed regulator 2055 to adjust the output power of the drive source, switching the power from water pump 203 to suction moving component 209; extracting stored heat: slider 2053 pushes the heat insulation ring 5 open through heat conduction rod 2056, opening the heat conduction path between heat conduction rod 2056 and cooling pipe 204; at the same time, suction ring 2094 of suction moving component 209 begins to slide back and forth, driving heat absorption net 2057 to move back and forth in heat storage box 208 through push rod 6, continuously absorbing the heat stored in phase change material, and dissipating it through heat conduction rod 2056. Heat is transferred to the medium inside the cooling pipe 204. This invention creatively integrates three functions—medium flow regulation, circulation path switching, and heat storage extraction—into a single linkage mechanism by setting a shape memory alloy strip 2051 to simultaneously connect the sealing block 2052, the slider 2053, and the heat-conducting rod 2056. When a low temperature is sensed, this linkage mechanism automatically and synchronously executes the above three actions to achieve rapid, accurate, and continuous heat preservation of the battery. This integrated design of "sensing and responding" avoids the response delay and coordination difficulties caused by multiple independent control systems, and realizes the adaptability, integration, and efficiency of the thermal management system. See attached document Figure 2-10The active heat dissipation component 211 includes an expansion column 2111, which is connected to the heat storage box 208. A movable ring 2112 is slidably connected inside the expansion column 2111, and the movable ring 2112 is elastically connected to the inside of the expansion column 2111 through a movable spring. A heat-conducting strip 2113 is fixedly connected inside the expansion column 2111, and a heat dissipation fin 2114 is fixedly connected to one side of the heat-conducting strip 2113. A fan blade 2115 is provided on one side of the heat dissipation fin 2114, and an impeller 2116 is fixedly connected to one side of the fan blade 2115. The impeller 2116 is rotatably connected to the inside of the heat-conducting pipe 206. When the charging pile operates at high power continuously, causing the temperature inside the heat storage box 208 to exceed the safety threshold, the medium inside the heat storage box 208 will expand due to heat and flow into the expansion column 2111 connected to it. The expanding medium will push the movable ring 2112 to slide smoothly inside the expansion column 2111, while compressing the movable spring to complete energy storage. This ensures that the movable ring 2112 and the heat-conducting strip 2113 fixedly installed inside the expansion column 2111 form a stable and tight contact, opening up the heat conduction path between the heat storage box 208 and the external heat dissipation structure. The excess heat inside the heat storage box 208 can be quickly and efficiently conducted to the heat dissipation fins 2114 fixedly connected at the end through the heat-conducting strip 2113, achieving rapid dispersion and dissipation of excess heat. This effectively solves the problems of phase change block thermal failure, irreversible degradation of heat storage performance, and even deformation and damage of the heat storage structure caused by continuous overheating inside the heat storage box 208, ensuring the safety of the heat storage system. The operation safety and service life are guaranteed; at the same time, the heat exchange medium continuously flowing inside the heat pipe 206 can drive the impeller 2116 installed inside it to rotate synchronously. The impeller 2116 drives the fan blade 2115 fixedly connected to its side to complete the coaxial synchronous rotation. The directional airflow generated by the rotation of the fan blade 2115 can continuously accelerate the air flow rate on the surface of the heat dissipation fin 2114, greatly improve the heat exchange efficiency between the heat dissipation fin 2114 and the external environment, and further accelerate the dissipation of excess heat. Moreover, the entire heat dissipation drive structure does not require an additional independent electric drive unit. It directly uses the kinetic energy of the circulating heat exchange medium to complete the drive, greatly reducing the energy consumption and structural complexity of the device. It ensures the safe and stable operation of the heat storage system under high temperature conditions throughout the process, and avoids the problems of cooling failure of the core components of the charging pile, limited charging power, or even equipment failure and shutdown caused by the overheating of the heat storage system. The heat dissipation fins 2114 are provided with a guide box 9 on their outer side, and the guide box 9 is fixedly connected to the charging pile body 1. A control valve 10 is connected to one side of the guide box 9. The control valve 10 is existing technology and is electrically connected to the micro switch 2054. The guide box 9, which is fixedly installed on the charging pile body 1 and covers the outer side of the heat dissipation fins 2114, can accurately guide and constrain the directional airflow generated by the rotation of the fan blades 2115, avoid the disorderly diffusion of airflow in all directions and the loss of kinetic energy, and enable the airflow to act on the entire surface of the heat dissipation fins 2114 in a concentrated and stable manner. This further enhances the heat exchange efficiency between the heat dissipation fins 2114 and the flowing airflow, greatly improves the heat dissipation rate and heat dissipation uniformity under the over-temperature condition of the heat storage system, and effectively solves the problems of poor heat dissipation effect, delayed heat dissipation response and untimely cooling of the heat storage box 208 caused by airflow dispersion. At the same time, the guide box 9 can guide the airflow to the surface of the heat storage fins 2114. Box 9 can precisely guide the airflow carrying a large amount of heat after heat exchange to the external heat recovery pipe through the control valve 10 connected to its end, realizing the secondary recovery and reuse of waste heat during the heat dissipation process, further improving the overall energy utilization efficiency of the entire charging pile device. The external heat recovery pipe is an existing mature technology, which will not be described in detail here. When the micro switch 2054 is triggered by low temperature conditions such as severe cold at night, the micro switch 2054 can simultaneously control the control valve 10 to complete the closing action, completely blocking the connection between the guide box 9 and the external heat recovery pipe, effectively preventing the backflow of cold air from the outside into the guide box 9, and preventing the heat stored in the heat storage box 208 from being lost in reverse through the guide box 9 and the pipe, fully ensuring the retention rate and utilization efficiency of the stored heat under low temperature insulation conditions, and ensuring the stable and reliable heat insulation and heating effect of the battery pack and plug socket. The impeller 2116 has a sliding rod 11 fixedly connected to one side, and a rotating ring 12 is slidably connected inside the sliding rod 11. The rotating ring 12 is located inside the heat storage box 208 and is elastically connected to the sliding rod 11 via a support spring. When the impeller 2116 rotates under the flow of the heat exchange medium in the heat pipe 206, it can synchronously drive the sliding rod 11 fixedly connected to it to complete coaxial synchronous rotation. The sliding rod 11 synchronously drives the rotating ring 12 sleeved on its surface to complete synchronous rotation. During the continuous rotation of the rotating ring 12 inside the heat storage box 208, it can fully agitate the phase change blocks filled in the heat storage box 208, so that the temperature is evenly distributed throughout the phase change blocks. This effectively solves the problem of insufficient phase change, excessively high or low local temperature caused by excessively rapid local heat absorption of the phase change blocks, greatly improving the uniformity and stability of the entire heat storage and release process of the phase change blocks, and avoiding the problems caused by the phase change blocks. Uneven temperature distribution leads to a decrease in overall heat storage efficiency and an unstable heat release rate. The support spring, which is sleeved on the surface of the sliding rod 11 and fixedly connected to the sliding rod 11 and the rotating ring 12 at both ends, can drive the rotating ring 12 to complete a smooth and adaptive sliding adjustment on the sliding rod 11. When the heat absorption net 2057 moves back and forth with the push rod 6, the rotating ring 12 can be pushed by the heat absorption net 2057 to complete the corresponding position flexibly adjustment, always maintaining effective contact with the heat absorption net 2057. At the same time, the continuously rotating ring 12 can thoroughly and evenly scrape and clean the solidified phase change block attached to the surface of the heat absorption net 2057, effectively solving the problem of decreased thermal conductivity and obstructed heat conduction caused by the solidified phase change block. It ensures that the heat absorption and conduction effect of the heat absorption net 2057 is stable and reliable throughout the process, further improving the continuity and efficiency of heat storage heat release. The sliding rod 11 is fixedly connected to a spring box 13 via an overrunning clutch, and the spring box 13 is fixedly connected to the heat storage box 208. A plug 14 is provided on the top of the rotating ring 12, and the plug 14 is fixedly connected to the heat storage box 208. When the sliding rod 11 rotates synchronously with the impeller 2116, the overrunning clutch on its surface can stably drive the spring in the spring box 13 to complete the winding action, achieving efficient storage of mechanical energy and effectively recovering and utilizing the excess kinetic energy generated during the heat exchange medium circulation process, reducing the additional energy loss of the entire device. When the heat exchange medium circulation stops, causing the impeller 2116 to stop rotating, the pre-stored spring in the spring box 13 can smoothly release the stored energy, driving the sliding rod 11 and the rotating ring 12 to rotate continuously, constantly and uniformly disturbing the phase change block in the heat storage box 208, effectively solving the problem of the impeller 2116 stopping. The phase change block exhibits temperature stratification and localized solidification issues. This system ensures uniform temperature distribution throughout the phase change block, continuously improving the stability and consistency of its heat storage and release processes. The one-way transmission characteristic of the overrunning clutch effectively prevents overload energy storage during the winding of the spring, preventing plastic deformation or fatigue damage due to excessive stretching and significantly extending the service life of the elastic energy storage components. Simultaneously, in conjunction with the displacement of the heat absorption mesh 2057 caused by the push rod 6, the insert block 14, fixedly installed inside the heat storage box 208, precisely limits the rotational ring 12 when it slides adaptively to a designated position with the support spring. This allows the rotational power released by the spring to maintain a longer effective duration, preventing transmission failure caused by excessive displacement of the rotational ring 12. This ensures the long-term stable and reliable operation of the entire disturbance mechanism and heat storage system. It is worth noting that the specific selection of springs (including tension springs, movable springs, support springs, return telescopic columns, torsion springs, etc.) and other key components involved in this technical solution should be adapted according to actual working conditions such as pressure, frequency, and load to meet the performance requirements for long-term stable operation. Corresponding components and structures can be replaced or adjusted according to specific usage needs. Some springs and elastic elements are not shown in the attached drawings. The sliding and movement of each moving part are achieved through reasonable limiting and guiding structures in existing technologies (not fully shown in the figures) to ensure coordinated function and reliable operation of each mechanism. Furthermore, conventional protective or additional limiting structures can be added to relevant components according to specific usage environments and requirements. Various action thresholds and triggering conditions can also be adjusted according to actual usage needs. All connections in the liquid flow path are sealed using sealing structures to prevent leakage, forming a reliable dynamic or static sealing system to effectively eliminate liquid leakage. The circuit control section and electrical connections are not shown in the figures, but are reasonably laid out and implemented based on existing technologies.
[0023] Working principle: During use, the charging pile body 1 is connected to the power grid and provides high-power charging services for new energy vehicles through the charging plug. The battery pack simultaneously completes the storage and distribution of electrical energy. At this time, the heat recovery and insulation mechanism 2 starts simultaneously and enters the normal heat exchange cycle state. The drive source drives the transmission rod 201 to rotate synchronously. The transmission rod 201 drives the water pump 203 to operate stably through the cooperation of the ratchet 202 and the pawl. The water pump 203 draws heat exchange medium from the water storage tank 210 and delivers it to the cooling pipe 2, which is wound and connected to the heat dissipation plate of the charging pile body 1, through a one-way valve. Inside the cooling pipe 204, the heat exchange medium fully absorbs the redundant heat generated by the charging pile body 1 and the battery pack during high-power operation, completing the basic cooling and protection of the core electrical components and preventing performance degradation or shortened service life of the core components due to continuous high temperature. The heat-carrying heat exchange medium flows into the stacked heat conduction pipes 206 through the cooling pipe 204. The unidirectional heat conduction plate 207 conducts the heat carried by the heat exchange medium in the heat conduction pipe 206 unidirectionally to the heat storage box 208. The phase change block in the heat storage box 208 efficiently absorbs and stably stores the heat. The heat exchange medium recovers and stores waste heat during the charging process, significantly reducing energy consumption. After heat transfer, the heat exchange medium flows back to the water storage tank 210 via a three-way valve, forming a complete closed-loop heat exchange cycle. During this process, the shape memory alloy strip 2051 in the flow regulation component 205 senses the temperature of the heat exchange medium in the cooling pipe 204 in real time through the heat absorption block 3. It undergoes adaptive deformation as the temperature changes, simultaneously driving the sealing block 2052 to slide within the cooling pipe 204. This flexibly adjusts the effective flow cross-sectional area inside the cooling pipe 204, thereby precisely controlling the flow rate of the heat exchange medium and achieving fully automatic adaptive adjustment of heat exchange efficiency according to changes in charging conditions. Simultaneously, the shape memory alloy strip 2051 deforms, driving the slider 2053 to slide synchronously. The slider 2053 adjusts the output power of the drive source through the mechanical speed regulator 2055, thereby adjusting the operating speed of the water pump 203. This coordinated action with the adjustment of the sealing block 2052 achieves precise dual control of medium flow rate and velocity without the need for an additional electronic control unit, significantly improving the response speed and operational reliability of the adjustment action. During normal heat exchange cycles, the transmission rod 201 rotates while simultaneously driving the driven bevel gear 2096 to rotate synchronously via the transmission bevel gear. The driven bevel gear 2096 drives the eccentric wheel 2095 to rotate coaxially. The eccentric wheel 2095 drives the suction ring 2094 to reciprocate within the suction column 2092 via a connecting rod, providing auxiliary power for the directional flow of the heat exchange medium. At this time, the three-way valve keeps the main flow path open, and part of the heat exchange medium flows through the three-way valve into the flow pipe 2091, which is wound and connected to the plug socket of the charging pile body 1. This fully absorbs the redundant heat generated when the plug socket operates with high current, completing the cooling and protection of the plug socket and preventing the plug socket from suffering insulation aging, increased contact resistance, or even burn-out damage due to continuous high temperature. After heat exchange, the medium flows into the suction column 2092 through the one-way regulating valve and then into the water storage tank through the one-way drain valve 2093. Within 210, an independent heat exchange cycle is completed for the plug socket. Simultaneously, as the suction ring 2094 slides back and forth, it drives the heat absorption mesh 2057 to move up and down within the heat storage box 208 via the push rod 6, continuously agitating the phase change block within the heat storage box 208. This allows the phase change block to absorb the heat conducted by the heat pipe 206 in all directions and evenly, avoiding the problem of reduced heat storage efficiency caused by insufficient phase change due to local heat absorption saturation of the phase change block. The impeller 2116 rotates synchronously under the drive of the heat exchange medium flowing within the heat pipe 206, driving the sliding rod 11 and the rotating ring 12 to rotate synchronously. The rotating ring 12 continuously agitates the phase change block, further improving the uniformity of heat storage in the phase change block. At the same time, when the sliding rod 11 rotates, it drives the spring in the spring box 13 to complete the winding and energy storage through the overrunning clutch, recovering and utilizing the excess kinetic energy generated by the circulation of the heat exchange medium, reducing the additional energy loss of the device. When the charging pile operates at high power continuously, causing the temperature inside the heat storage box 208 to exceed the safety threshold, the medium inside the heat storage box 208 expands due to heat and flows into the connected expansion column 2111. This pushes the movable ring 2112 to slide within the expansion column 2111 and compress the movable spring, causing the movable ring 2112 to form a stable and tight contact with the heat-conducting strip 2113, thus opening the heat conduction path between the heat storage box 208 and the external heat dissipation structure. The excess heat inside the heat storage box 208 is quickly conducted to the heat dissipation fins 2114 through the heat-conducting strip 2113 for initial dissipation. At the same time, the heat exchange medium flowing in the heat-conducting pipe 206 drives the impeller 21 16 rotates synchronously with fan blade 2115. The directional airflow generated by the rotation of fan blade 2115 is concentrated on the surface of heat dissipation fin 2114 by the constraint of guide box 9, which greatly accelerates the air flow rate on the surface of heat dissipation fin 2114, further improves heat dissipation efficiency, and quickly releases excess heat in heat storage box 208. This prevents heat storage box 208 and phase change block from failing or being damaged due to overheating, and ensures the long-term stable operation of the heat storage system. Guide box 9 guides the heat-carrying airflow after heat exchange to the external heat recovery pipeline through control valve 10 to complete the secondary recovery and utilization of waste heat, further improving the overall energy utilization efficiency of the device. When the charging pile is started or running in low-temperature environments such as nighttime frigid conditions, the shape memory alloy strip 2051 senses the low temperature of the heat exchange medium inside the cooling pipe 204 and undergoes reverse deformation. This causes the sealing block 2052 to slide and block the main flow path of the cooling pipe 204. Simultaneously, it causes the slider 2053 to slide and trigger the micro switch 2054. The micro switch 2054 synchronously controls the three-way valve to close the main flow path of the heat exchange medium to the water storage tank 210, controls the one-way drain valve 2093 to close, and releases the one-way regulating valve from its one-way conduction function. Together with the sealing action of the sealing block 2052, this creates a locally sealed environment within the internal space of the cooling pipe 204, heat conduction pipe 206, and flow pipe 2091 around the battery pack and plug socket, preventing heat exchange. The heat loss caused by the flow of the medium to the non-insulated area is ineffective; at the same time, when the slider 2053 slides, it drives the mechanical speed regulating plate 2055 to adjust the drive source to complete the reverse action. At this time, the pawl transmission structure between the ratchet 202 and the water pump 203 is disconnected from the power transmission, and the output power of the drive source is concentrated to be transmitted to the transmission bevel gear and the driven bevel gear 2096, which drives the suction ring 2094 to slide back and forth continuously in the suction column 2092, driving the heat exchange medium in the sealed space to circulate continuously, so that the medium temperature in the sealed space is kept uniform and consistent, and the occurrence of local low temperature areas is avoided; while the slider 2053 slides, it drives the heat conduction rod 2056 to move, pushing the heat insulation ring 5 to rotate against the torsion spring force, opening the heat conduction rod 2056. The heat conduction path between the cooling pipe 204 and the micro switch 2054 simultaneously controls the electromagnetic block 7 to generate magnetic force, which drives the heat-absorbing block 8 to move and release the heat insulation from the heat-absorbing mesh 2057. This allows the heat-absorbing mesh 2057 and the heat-conducting rod 2056 to form a stable heat conduction path through the heat-absorbing part of the heat-absorbing block 8. The heat-absorbing mesh 2057 quickly absorbs the heat pre-stored by the phase change block in the heat storage box 208 and quickly transfers it to the heat exchange medium in the cooling pipe 204 through the heat-conducting rod 2056, continuously heating the heat exchange medium. The heated heat exchange medium continuously circulates in the sealed space, providing continuous and stable heat preservation and heating for the battery pack and the charging pile body 1, effectively solving the problem of battery pack in low-temperature environments. Increased electrolyte viscosity slows lithium-ion migration, leading to increased internal resistance and resulting in reduced effective capacity, decreased charging and discharging efficiency, and limited charging power. Simultaneously, the heated medium flows synchronously through the flow pipe 2091, providing synchronous heat preservation to the plug socket, preventing poor contact and charging interruption caused by low-temperature frost formation. This ensures stable high-power output of the charging pile in low-temperature environments. During low-temperature insulation operation, the suction ring 2094 slides back and forth while driving the heat absorption net 2057 to move directionally back and forth within the heat storage box 208 via the push rod 6, continuously contacting different areas of the phase change block. This prevents the phase change block in a fixed position from solidifying after continuous heat absorption, ensuring the stability and continuity of heat conduction.After the impeller 2116 stops rotating, the pre-stored energy in the spring spring box 13 is released, driving the sliding rod 11 and the rotating ring 12 to rotate continuously and uniformly, preventing the phase change block from experiencing temperature stratification and localized solidification, thus ensuring the uniformity and stability of the phase change block's heat release process. Simultaneously, the rotating ring 12 slides adaptively with the support spring, maintaining effective contact with the heat absorption mesh 2057. The continuously rotating ring 12 thoroughly scrapes and cleans the solidified phase change block adhering to the surface of the heat absorption mesh 2057, ensuring stable and reliable thermal conductivity. The micro switch 2054 synchronously controls the control valve 10 to close, completely blocking the connection between the guide box 9 and the external heat recovery pipeline, preventing backflow of cold air from the outside, and preventing the heat stored in the heat storage box 208 from being lost in reverse through the guide box 9, ensuring the retention rate and utilization efficiency of the stored heat under low-temperature insulation conditions.
