Description

Technical Field

[0001] The present application belongs to the technical field of charging controllers, and specifically relates to an AC / DC integrated charging controller. Background Art

[0002] An AC / DC integrated charging controller is a controller that can provide both AC and DC charging for electric vehicles. This controller combines AC / DC and DC / DC conversion technologies and is suitable for different charging requirements of electric vehicles.

[0003] Traditional charging methods mainly include AC charging and DC charging. AC charging piles need to convert AC power into DC power through an on-board charger before charging the electric vehicle battery, while DC charging piles can directly convert AC power in the power grid into DC power to power the electric vehicle battery. However, with the increase in the types of electric vehicles and the diversification of charging needs, a single charging method can no longer meet market demand;

[0004] Compared with AC charging controller or DC charging controller, in order to meet the different charging requirements of electric vehicles, two different devices, AC charging controller and DC charging controller, need to be provided at the same time, which greatly increases the cost. The AC / DC integrated charging controller can support both AC charging and DC charging at the same time, and only one device is needed to meet the different charging requirements of electric vehicles.

[0005] However, since the existing AC / DC charging controller needs to process both AC and DC power sources, the number of components installed on its internal circuit board is greater than that of a DC or AC controller, which causes the heat generated by the electronic components to be more concentrated during operation. Especially in outdoor environments, high temperatures will make the heat dissipation problem of the charging controller more prominent, making it impossible to effectively disperse the heat, thereby affecting the overall heat dissipation efficiency of the charging controller housing. Therefore, an AC / DC integrated charging controller is provided. Utility Model Content

[0006] The purpose of this application is to provide an AC / DC integrated charging controller in order to solve the above-mentioned problems.

[0007] The technical solution adopted in the present application is as follows: an AC / DC integrated charging controller, comprising a charging controller housing, a rectangular fixing frame fixedly installed on the inner side wall of the charging controller housing, a heat absorbing mounting plate fixedly installed on the bottom surface of the rectangular fixing frame by means of arranged bolts, a heat absorbing baffle plate fixedly installed on the top surface of the heat absorbing mounting plate near the middle, a circuit board is respectively arranged on the left and right sides of the heat absorbing baffle plate on the top surface of the heat absorbing mounting plate, the circuit board is fixedly installed on the top surface of the heat absorbing mounting plate by means of arranged screws, a heat sink is fixedly installed on the bottom surface of the heat absorbing mounting plate, the bottom end of the heat absorbing baffle plate is fixed to the top surface of the heat sink plate, a plurality of heat sink fins are installed in an array at equal intervals on the bottom surface of the heat sink plate, and a plurality of convection holes are respectively provided on the left and right sides of the charging controller housing.

[0008] In a preferred embodiment, a sealing bottom plate is fixedly mounted on the bottom surface of the charging controller housing by means of hexagon socket bolts.

[0009] In a preferred embodiment, a plurality of heat dissipation bumps are installed in an array with equal spacing on the left and right sides of the charging controller housing.

[0010] In a preferred embodiment, fixing plates are fixedly mounted on the left and right sides of the sealing bottom plate, respectively, and mounting holes are formed on the top surfaces of the fixing plates.

[0011] In a preferred embodiment, a dustproof screen is fixedly installed inside the convection hole.

[0012] In a preferred embodiment, a display panel is fixedly mounted on the top surface of the charging controller housing.

[0013] In summary, due to the adoption of the above technical solution, the beneficial effects of this application are:

[0014] 1. In the present application, due to the adoption of the above-mentioned scheme, after the charging pile is installed with the AC / DC integrated charging controller, it can be equipped with an AC charging gun and a DC charging gun at the same time to meet the different charging needs of electric vehicles. When the electric vehicle needs AC charging, plug in the AC charging gun, and the AC circuit board and electronic components inside the AC / DC integrated charging controller will work together to provide AC charging output. Similarly, when the electric vehicle needs DC charging, plug in the DC charging gun, and the DC circuit board and electronic components of the AC / DC integrated charging controller will work together to provide DC charging output, which is compatible with the different charging needs of electric vehicles and saves equipment costs. At the same time, through the synergistic effect of the heat-absorbing mounting plate, the heat-absorbing partition, the heat-dissipating plate, and the heat-dissipating fins, the heat dissipation performance of the charging controller housing is effectively improved, ensuring the stable operation and high efficiency of the equipment in different environments.

DETAILED DESCRIPTION

[0019] In order to make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme in the embodiments of the present application will be clearly and completely described below in combination with the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0020] refer to Figure 1 , Figure 2 and Figure 3 An AC / DC integrated charging controller comprises a charging controller housing 1, a display panel 14 is fixedly mounted on the top surface of the charging controller housing 1, a rectangular fixing frame 2 is fixedly mounted on the inner side wall of the charging controller housing 1, and a heat absorbing mounting plate 3 is fixedly mounted on the bottom surface of the rectangular fixing frame 2 by means of bolts; the display panel 14 is provided to facilitate the interactive interface between the user and the charging controller, and to display key information during the charging process, so that the user can monitor the charging status and parameters in real time; the middle part of the rectangular fixing frame 2 is a hollow structure, so that the raised part in the middle part of the heat absorbing mounting plate 3 can pass through the middle part of the rectangular fixing frame 2 when the mounting plate 3 is installed by means of bolts.

[0021] refer to Figure 2 , Figure 3 A heat absorbing baffle 4 is fixedly installed on the top surface of the heat absorbing mounting plate 3 near the middle; the heat absorbing mounting plate 3 and the heat absorbing baffle 4 can be made of copper or aluminum alloy materials. Copper and aluminum alloy, these two materials have extremely high thermal conductivity, can quickly absorb and transfer heat, and the set heat absorbing baffle 4 can facilitate the separation of the top surface of the heat absorbing mounting plate 3 into two installation areas.

[0022] refer to Figure 2 , Figure 3The top surface of the heat absorbing mounting plate 3 is located on the left and right sides of the heat absorbing baffle 4, and circuit boards 5 are respectively arranged. The circuit boards 5 are fixedly mounted on the top surface of the heat absorbing mounting plate 3 by screws. Two circuit boards 5 are installed on the top surface of the heat absorbing baffle 4. One of the two circuit boards 5 is a circuit board 5 for controlling AC, and the other is a circuit board 5 for controlling DC. The two circuit boards 5 have different circuit designs and components to adapt to the characteristics of AC and DC.

[0023] Specifically, the controller consists of a charging controller housing 1 and a main control board (i.e., a circuit board). The main control board is equipped with an AC-DC converter and an advanced control system, which can realize efficient conversion from AC to DC. The onboard power supply provides a stable, low-voltage power supply for the main control board to ensure its normal operation. In addition, the main control board also provides AC charging output by controlling the AC relay. The vehicle battery management system interacts with data in real time to ensure accurate control of the charging process. The main control board also integrates a DC power supply module to provide DC charging output for electric vehicles. At the same time, the main control board has a powerful real-time monitoring function, which can collect charging operation data in real time and automatically shut down in abnormal conditions to ensure the safety of the charging process. The voltage detection circuit and the temperature detection circuit work together to provide a comprehensive protection mechanism for the AC / DC integrated charging controller, including overvoltage protection. Protection, over-current protection and over-temperature protection, etc., greatly improve the stability and safety of the system, and the output DC power will be accurately adjusted by the DC-DC converter (such as Buck, Boost or Buck-Boost converter) for voltage and current adjustment to meet the charging needs of different devices. The converter can intelligently adjust the charging rate according to the battery status and needs to ensure safe and efficient charging. It is responsible for monitoring and managing the battery status, including key parameters such as battery voltage, current, temperature and charge status. This system ensures that the battery is charged in the best condition, thereby extending its service life. Whether it is AC or DC, it can be safely and efficiently provided to electric vehicles through this system, meeting the different charging needs of electric vehicles. This design not only improves the charging efficiency, but also greatly enhances the stability and safety of the system.

[0024] refer to Figure 2 , Figure 3 A heat sink 6 is fixedly installed on the bottom surface of the heat-absorbing mounting plate 3, the bottom end of the heat-absorbing baffle 4 is fixed to the top surface of the heat sink 6, and a plurality of heat-dissipating fins 7 are installed in an array at equal intervals on the bottom surface of the heat sink 6. A plurality of convection holes 8 are respectively provided on the left and right sides of the charging controller housing 1, and a dust-proof shielding net 13 is fixedly installed inside the convection holes 8; when the heat adsorbed on the heat-absorbing mounting plate 3 and the heat-absorbing baffle 4 is transferred to the heat sink 6 and the heat-dissipating fins 7, the outside air flows through the convection holes 8, so that the heat on the heat sink 6 and the heat-dissipating fins 7 can be quickly taken away, thereby achieving the effect of heat dissipation inside the charging controller housing 1.

[0025] refer to Figure 1 , Figure 2 The bottom surface of the charging controller housing 1 is fixedly installed with a sealing bottom plate 9 by means of the hexagon socket bolts, and the left and right sides of the sealing bottom plate 9 are respectively fixedly installed with fixing plates 11, and the top surface of the fixing plate 11 is provided with a mounting hole 12; the bottom surface of the charging controller housing 1 is an open structure, and the sealing bottom plate 9 is provided to facilitate sealing the bottom of the charging controller housing 1. When the sealing bottom plate 9 is disassembled, the heat absorption mounting plate 3 and the circuit board 5 can be disassembled, so that it is convenient to replace or maintain the components.

[0026] refer to Figure 1 , Figure 2 A plurality of heat dissipation bumps 10 are installed in an array with equal spacing on the left and right sides of the charging controller housing 1; the heat dissipation bumps 10 are arranged to further improve the heat dissipation effect of the charging controller housing 1.

[0027] The implementation principle of an AC / DC integrated charging controller embodiment of the present application is as follows: the operator first installs the circuit board 5 on the heat absorption mounting plate 3, and then connects the circuit board 5 to the output connector on the side of the charging controller housing 1 through the line, and then uses bolts to fix the heat absorption mounting plate 3 to the bottom of the rectangular fixing frame 2, so that the circuit board 5 can be stably installed inside the charging controller housing 1, and then, the sealing bottom plate 9 is installed to cover the bottom of the charging controller housing 1 to form an overall package to protect the components on the internal circuit board 5 from external interference;

[0028] When the circuit board 5 is installed, the top of the heat absorbing mounting plate 3 is divided into two areas by the heat absorbing partition plate 4, one area is used to install the circuit board 5 for controlling direct current, and the other area is used to install the circuit board 5 for controlling alternating current. This design avoids the mutual interference of heat between the two circuit boards 5 and prevents the occurrence of heat island effect.

[0029] When the circuit board 5 generates heat during operation, the heat absorbing mounting plate 3 and the heat absorbing baffle plate 4 can effectively absorb the heat. Subsequently, the heat is transferred to the heat dissipation plate 6 and the heat dissipation fins 7 through the heat absorbing mounting plate 3 and the heat absorbing baffle plate 4. The outside air flows through the convection holes 8 to quickly take away the heat on the heat dissipation plate 6 and the heat dissipation fins 7, thereby realizing rapid heat dissipation inside the charging controller housing 1.

[0030] The device is reasonably designed and easy to operate, ensuring that the heat sink 6 and the heat sink fins 7 are not damaged during movement and transportation. At the same time, the connection and installation method of the heat-absorbing mounting plate 3 and the rectangular fixing frame 2 prevents the top circuit board 5 from being affected by dust in the convective air, thereby improving the overall sealing and heat dissipation effect. Through the synergistic effect of the heat-absorbing mounting plate 3, the heat-absorbing partition plate 4, the heat sink 6 and the heat sink fins 7, the heat dissipation performance of the charging controller housing 1 is effectively improved, ensuring the stable operation and high efficiency of the equipment in different environments.

Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present application.
