1.Technical principles and core parameters:
The device adopts a dual gun independent control architecture, and each charging gun can adjust the output current separately, supporting two vehicles to charge at different powers simultaneously. The output end is converted into direct current and directly supplies power to the vehicle battery, reducing energy conversion losses. The metal casing and IP54 protection level design can resist dust intrusion and low-pressure water jet splashing, adapting to complex outdoor environments.
2.Security protection and intelligent management:
The device is equipped with multiple safety mechanisms: overvoltage protection can monitor the output voltage in real time and automatically cut off the power supply in case of abnormalities; Overcurrent protection limits the maximum output value through current sensors to prevent battery overload; Overheating protection relies on temperature sensors and intelligent temperature control systems. When the temperature of the casing exceeds a threshold, the cooling fan will be activated or the power will be reduced; In emergency situations, users can immediately stop charging by pressing the quick emergency stop button. These functions collectively ensure the safety of the charging process.
3.Technical advantages and actual performance:
Compared to single gun charging stations, the dual gun design can improve the charging efficiency of the service area by more than 50%, especially during peak traffic periods, which can effectively reduce queuing time. The independent current regulation function allows two vehicles to charge at different powers (such as one 250A and one 150A), avoiding waste of power resources. The combination of IP54 protection level and metal casing enables it to operate stably in ambient temperatures ranging from -20 ℃ to 50 ℃, adapting to the climate conditions in most parts of the world. In addition, the device supports remote monitoring and fault diagnosis, which facilitates timely handling of abnormalities by operation and maintenance personnel.
As an important component of electric vehicle charging infrastructure, intelligent dual gun DC charging piles have broad application prospects in various fields such as urban public charging networks, highway service areas, commercial and office areas, residential areas and parking lots, shared travel, and logistics distribution, thanks to their high efficiency, safety, and intelligence. With the continuous advancement of technology and the growth of market demand, intelligent dual gun DC charging piles will further promote the popularization and development of electric vehicles, making important contributions to achieving green transportation and sustainable development goals.
