Description

Technical Field

[0001] The utility model relates to the technical field of direct current charging, in particular to a box-type outdoor direct current charging device. Background Art

[0002] The box-type outdoor DC charging device is a kind of power equipment designed for outdoor environment. It is mainly used for fast charging of electric vehicles (EV) and other direct current (DC) power equipment. This device is usually installed in public parking lots, commercial buildings, residential areas or other outdoor places. It aims to provide convenient charging services for electric vehicles, thereby promoting the popularization and use of electric vehicles.

[0003] Box-type outdoor DC charging devices usually consist of the following main parts: Charging module This is the core part of the device, responsible for converting the AC power of the power grid into DC power to supply the electric vehicle battery. The performance of the charging module directly affects the charging speed and charging efficiency; cooling system. Since a lot of heat will be generated during the charging process, there must be an effective cooling system to ensure the normal operation of the charging module and other components. The cooling system may include components such as fans and heat exchangers; the control system is used to monitor the charging process, including charging status, power consumption, temperature monitoring, etc., to ensure the safety and efficiency of the charging process. The control system usually has a user interface to allow users to set up charging and diagnose faults; protection devices, including overload protection, short circuit protection, leakage protection, etc., to ensure the safety of the charging process and prevent fire or electric shock accidents caused by electrical faults; shell, protect the internal electronic components from environmental factors such as rain, direct sunlight, temperature changes, etc. The shell material is usually corrosion-resistant and UV-resistant.

[0004] Box-type outdoor DC charging devices are suitable for a variety of scenarios, such as public parking lots, commercial buildings, residential areas and highway service areas. Charging stations are set up in service areas. The advantages of box-type outdoor DC charging devices include fast charging, which can fully charge electric vehicles in a shorter time than home charging. It is flexible and can be installed in different locations as needed without being restricted by fixed lines. It can be deployed on a large scale and can provide services for more electric vehicles.

[0005] In summary, the box-type outdoor DC charging device is an important infrastructure to support the popularization of electric vehicles and green travel. Its design and application need to comprehensively consider multiple factors such as technology, economy and environment. With the advancement of technology and the reduction of costs, this device will play a more important role in future cities and transportation systems.

[0006] The existing box-type outdoor DC charging device is generally aimed at improving the technical problems of low heat dissipation efficiency and short life of the AC conductive bar caused by the AC conductive bar being arranged in the heat dissipation channel of the current DC charging device. For example, a box-type outdoor DC charging device disclosed in the authorized Chinese patent CN212827943U can reduce the influence of the AC conductive bar on the wind resistance of the heat dissipation channel and improve the heat dissipation efficiency through the coordinated use of structures such as the power module compartment, the front fixing plate, the rear fixing plate, the fixing column, the fixing plate folding edge, the AC conductive bar bracket, the AC conductive bar, the terminal fixing plate, the DC output line clamp, the fan, the power module, the main controller, the metering unit, the DC connection module, the power distribution positive control board, the power distribution negative control board, the AC incoming line connection module, the AC incoming line fixing plate, the surge protector, the AC contactor and the molded case circuit breaker. The heat dissipation efficiency is improved. At the same time, the AC conductive bar is arranged in the line passage to avoid direct hot air blowing, thereby improving the life of the AC conductive bar.

[0007] However, the box-type outdoor DC charging device in the above-cited document is large in size and heavy in weight, so during the transfer process, multiple staff members need to cooperate and use special mobile equipment to move it from one location to another predetermined location. This process not only consumes a lot of physical strength, but also wastes a lot of human resources, causing inconvenience to the staff, but also limits the flexible use of the device in different locations. If mobile wheels can be installed on the box-type outdoor DC charging device, although this will make it easier to move to the designated location, the problem is that even if a braking system is installed, the existing braking device can only achieve deceleration and cannot ensure that the device is stable and motionless in a stationary state. This means that even under the action of the brake, the device may still be displaced under the action of external forces, so that it cannot be firmly fixed in the required working position, thereby affecting the normal operation of the device, resulting in the use effect of the existing box-type outdoor DC charging device needs to be improved.
