[0030] The following embodiments of the present invention are described in detail with reference to the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments may be combined with each other.
[0031] In related technologies, charging piles convert high-voltage alternating current (AC) into DC suitable for charging electrical devices during charging. Charging piles can use split-type charging stacks, where the cooling components must be used in conjunction with the main unit. Split-type charging stacks occupy a large area and cannot be flexibly moved. Therefore, to minimize the impact of heat generated during charging, charging piles typically use a split-type structure. However, split-type charging piles take up a large amount of space and are less convenient.
[0032] refer to Figure 1 As shown, in order to solve the above technical problems, an embodiment of the present application provides a charging device 100, which is suitable for charging electrical equipment. The charging device 100 includes a shell 110, a control component 120, a charging component 130 and a cooling component 140.
[0033] Combine Figures 1 to 3 As shown, the housing 110 defines a first cavity 111 and a second cavity 112. The housing 110 provides a storage space for the charging device 100, and the storage space is divided into the first cavity 111 and the second cavity 112. The control component 120 is disposed in the first cavity 111; the charging component 130 includes a power supply 131 and a charging component. The power supply 131 is disposed in the second cavity 112. The charging component is electrically connected to the power supply 131 via a charging cable. The power supply 131 is used to provide electrical energy to the charging component. The charging component is plugged into and charges the electrical device. The cooling component 140 is disposed in the second cavity 112. The cooling component 140 is disposed near the charging cable of the charging component and is connected to the charging cable of the charging component to cool the charging cable of the charging component. The power supply 131 is located between the cooling component 140 and the control component 120. The control component 120 is electrically connected to the power supply 131 and the cooling component 140 respectively. Accordingly, the shell 110 is limited to form a first cavity 111 and a second cavity 112. The control component 120 is installed in the first cavity 111, and the power supply 131 and the cooling component 140 are both installed in the second cavity 112, so as to realize the separation between the control component 120 and other components and reduce the interference and obstruction to the control component 120. The control component 120 can control the power supply 131 to charge through the charging component. At the same time, the cooling component 140 cools the charging component and the power supply 131 to reduce the overheating of the charging component 130 during use, thereby extending the service life of the charging device 100. The control component 120, the charging component 130 and the cooling component 140 in the charging device 100 are integrated, with high space utilization, which increases the usage scenarios of the charging device 100.
[0034] Exemplarily, the charging component includes a charging cable, and the cooling component 140 can perform liquid cooling on the charging cable of the charging component. By circulating coolant inside the charging cable, the heat problem during the charging process can be effectively reduced, so that the cable can be kept at a low temperature even in a large current fast charging state, ensuring safety and efficiency.
[0035] It is understood that the control component 120 is responsible for managing and controlling various functions of the charging device 100 during the charging process, which may include but are not limited to charging power regulation, safety protection, user interface management, and communication functions.
[0036] Electrical equipment can be vehicles, portable devices, ships, spacecraft, and power tools, etc. Spacecraft include aircraft, rockets, space shuttles, and spacecraft, etc. Power tools include metal cutting power tools, grinding power tools, assembly power tools, and railway power tools.
[0037] For the convenience of explanation, the electrical equipment is taken as an example of a vehicle. The vehicle can be a new energy vehicle, which can be a pure electric vehicle, a hybrid vehicle or an extended-range vehicle, etc. A battery is provided inside the vehicle, and the battery can be provided at the bottom, head or tail of the vehicle. The battery can be used to power the vehicle, for example, the battery can be used as the operating power source of the vehicle. The vehicle may also include a controller and a motor, and the controller is used to control the battery to power the motor, for example, for the starting, navigation and working power requirements of the vehicle during driving. The battery can not only serve as the operating power source of the vehicle, but also as the driving power source of the vehicle, replacing or partially replacing fuel or natural gas to provide driving power for the vehicle.
[0038] Combine Figures 1 to 3 As shown, the charging device 100 has a first direction X, a second direction Y, and a third direction Z, wherein the first direction X, the second direction Y, and the third direction Z are arranged perpendicular to each other. For example, the first direction X is the height direction of the charging device 100, the second direction Y is the length direction of the charging device 100, and the third direction Z is the width direction of the charging device 100.
[0039] In one embodiment, optionally, Figure 3 As shown, the charging device 100 has a first direction X. Along the first direction X, the control component 120, the power supply 131 and the cooling component 140 are arranged in sequence, that is, along the height direction of the charging device 100, the control component 120, the power supply 131 and the cooling component 140 are arranged in sequence. The power supply 131 is located between the control component 120 and the cooling component 140, so that the control component 120 can distribute and control the output power of the power supply 131. The cooling component 140 is close to the power supply 131 to cool the power supply 131.
[0040] Exemplarily, the cooling component 140 may include a liquid cooling module, which passes a circulating liquid (usually a coolant) through the heat-generating component, absorbs heat, and then dissipates it into the environment or the circulation system through a radiator or a heat exchanger. Alternatively, the cooling component 140 may include a liquid cooling module and an air cooling module, and the air cooling module uses a fan or natural convection to allow air to flow through the surface of the heat-generating component to take away the heat. Of course, the cooling component 140 may also include a liquid cooling module and an air cooling module, and adopts liquid cooling and air cooling methods to dissipate heat and cool down the charging component and the power supply component 131, which has better technical effects. The liquid cooling module in the cooling component 140 can dissipate heat and cool down the charging cable of the charging component, thereby achieving better cooling effect.
[0041] In one embodiment, optionally, reference Figure 3As shown, the power supply 131 includes a plurality of conversion components 1311 and a plurality of storage compartments 1312. The plurality of storage compartments 1312 are arranged in an array structure. One conversion component 1311 is arranged in one storage compartment 1312. One conversion component 1311 is placed in one storage compartment 1312, so that the plurality of conversion components 1311 can be placed separately to reduce the obstruction and influence between the plurality of conversion components 1311. Exemplarily, the plurality of conversion components 1311 can be arranged in parallel, and any conversion component 1311 is used to realize a part of the power conversion, which can improve the conversion power of the charging device 100 and is also convenient for maintenance and expansion.
[0042] It can be understood that the conversion element 1311 can be an AC / DC converter or rectifier, which is used to convert alternating current into direct current, so as to convert the alternating current (AC) obtained from the power grid into direct current (DC) suitable for charging electric vehicle batteries, ensuring that the electric energy is efficiently and safely transmitted to the power-consuming equipment.
[0043] Optionally, two adjacent storage chambers 1312 are separated by a first partition 1313. The first partition 1313 is used to separate the storage chambers 1312. Two adjacent conversion parts 1311 are separated by a first partition 1313, which is beneficial to the use and heat dissipation of the conversion parts 1311. Multiple storage chambers 1312 are used to facilitate the management and replacement of the conversion parts 1311 in the storage chamber 1312.
[0044] In one embodiment, optionally, reference Figure 2 and Figure 3 As shown, the charging device 100 also has a second direction Y, which is set at an angle to the first direction X. The shell 110 includes a second partition 114. Along the second direction Y, the second partition 114 separates the shell 110 into the first cavity 111 and the second cavity 112, that is, the second partition 114 is set along the length direction of the charging device 100. The control component 120 and the charging component 130 can be separated by the second partition 114. The control component 120 is installed in the first cavity 111, and the charging component 130 is installed in the second cavity 112.
[0045] In one embodiment, optionally, at least one gun holder 115 is provided on opposite sides of the housing 110 along the second direction Y. The charging component includes multiple charging guns (not shown in the figure). The charging gun is a component for realizing power transmission. The charging gun must comply with the corresponding charging interface standards and be able to withstand the mechanical strength of multiple plugging and unplugging. One charging gun is detachably connected to one gun holder 115. The charging gun is plugged into the electrical device to charge the electrical device. The number of gun holders 115 can be two, four, six or eight. For example, the number of gun holders 115 is four. The four gun holders 115 are respectively provided on opposite sides of the housing 110 along the length direction of the charging device 100. The number of charging guns is four. Four charging guns can charge four electrical devices at the same time, thereby improving charging efficiency.
[0046] In one embodiment, optionally, Figure 1 As shown, the housing 110 is provided with at least one heat dissipation window 113, which is positioned corresponding to the cooling assembly 140. The heat dissipation window 113 promotes natural air convection, helping to dissipate heat from the interior, extending the service life and improving safety. For example, the second cavity 112 is connected to the outside through the heat dissipation window 113, facilitating air circulation, allowing heat exchange between the cooling assembly 140 and the outside world, and improving heat dissipation and cooling effects.
[0047] In this embodiment, combined with Figure 1 and Figure 2 As shown, the charging device 100 further has a third direction Z, which is arranged at an angle to the second direction Y and the first direction X respectively. The number of the heat dissipation windows 113 is two, and the two heat dissipation windows 113 are arranged on opposite sides of the shell 110 along the third direction Z, that is, the two heat dissipation windows 113 are located on opposite sides of the shell 110 along the width direction of the charging device 100. The two heat dissipation windows 113 are arranged opposite to each other and are located at the same height. The air between the two heat dissipation windows 113 can naturally convect and can take away the heat of the cooling component 140, thereby having a better heat dissipation effect.
[0048] Alternatively, as Figure 1As shown, the housing 110 includes a first housing 116 and a second housing 117. The first housing 116 and the second housing 117 define an enclosed space. The first housing 116 and the second housing 117 are movably connected. When the second housing 117 closes the opening of the first housing 116, the internal environment of the charging device 100 is isolated from the external environment. When the second housing 117 moves relative to the first housing 116, the second housing 117 can be opened to facilitate inspection and maintenance by personnel. For example, the first housing 116 is a cabinet, and the second housing 117 is a cabinet door. One end of the cabinet door is mounted on the cabinet via a hinge, and the other end of the cabinet door can be locked or opened with the cabinet. The housing 110 can be of various shapes and sizes, such as a rectangular parallelepiped, a quadrangular prism, a hexagonal prism, a cylinder, etc. The first housing 116 and the second housing 117 can also be made of various materials, such as copper, iron, aluminum, stainless steel, aluminum alloy, etc., but this embodiment of the present application does not impose any particular limitations on this. Exemplarily, there are two second shells 117 , and the two second shells 117 are disposed along the second direction Y at opposite sides of the first shell 116 .
[0049] Furthermore, the charging device 100 further includes a base 150 , which is mounted on the bottom of the housing 110 . The base 150 supports the housing 110 and facilitates movement and transportation of the charging device 100 .
[0050] In one embodiment, optionally, reference Figure 4 As shown, the control assembly 120 includes a first control member 121, a second control member 122 and a third control member 123. The first control member 121 is electrically connected to the second control member 122 and the third control member 123 respectively. The first control member 121 can control the second control member 122 and the third control member 123. The first control member 121 and the second control member 122 are arranged in sequence along the third direction Z, and the third control member 123 is arranged on the side wall of the housing 110. Accordingly, the first control member 121 is a controller, and the controller controls the entire charging device 100. For control, the second control component 122 is a matrix component, which is used to distribute and control the output power of the power supply component, perform power management according to the grid load, and realize intelligent scheduling of the charging device 100. The third control component 123 is a charging gun controller, which can control the start and stop of charging, and display and monitor the status of the charging gun. The charging status is displayed through the display module 160 set on the shell 110, such as whether it is correctly connected, charging, full, etc., and temperature monitoring, short circuit protection, leakage protection, etc., to ensure safety during the charging process.
[0051] An embodiment of the present invention further provides a charging system (not shown in the figure), including the charging device 100 described in any one of the above embodiments. The charging system has all the beneficial effects of the charging device 100 described in any one of the above embodiments, which will not be described in detail here.
[0052] In all examples shown and described herein, any specific values should be interpreted as merely exemplary and not limiting, and thus other examples of the exemplary embodiments may have different values.
[0053] The above-described embodiments merely represent several implementation methods of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the scope of the present invention, all of which fall within the scope of protection of the present invention.
