The charging pile is a charging device for new energy electric vehicles, that is, it provides AC slow charging (3.5KW-7KW/220V) and DC fast charging for the lithium iron phosphate batteries of electric vehicles with on-board chargers (handshake battery BMS management system). The special charging device for charging (30KW-360KW-445KW/380V-500V-750V) electric energy is a solid pile, so we named it the charging pile.
The charging pile can meet the charging mode: automatic, timing, fixed fee, quantitative, appointment, three{{0}}level lightning protection, two-level metering, protection level up to IP54, working temperature: -20-50 degree , guide symbols GB18487 and GB20234 and 27930-2015 Five major standards. Communication methods: Ethernet, CAN, RS485, wireless communication, support China Telecom, voltage: 200V-380V-750V, current: 16A-250A-470A, integrated power: 7KW-360KW, split power: 180KW-445KW, with power supply Module, card swiping and charging system, to realize the 3.0G interconnection of "car networking, pile networking, Internet", APP (two-dimensional code scanning) billing access to the platform monitoring system, enter the financial charging management, in line with the standards of the State Grid Corporation and the country The electric vehicle standard (2015 No. 40 standard) has a 10-year guarantee and a 2-year quality guarantee. The factory products have obvious signs: LOGO, product number, operating instructions, safety signs, quality insurance, State Grid and third-party CMA inspection report compilation, national quality certification CQC and CCC, etc.
The working principle of Huayuan charging pile
The electrical system design of the AC charging pile is shown in the figure. The main circuit consists of an input protection circuit breaker, an AC smart meter, an AC control contactor and a charging interface connector; the secondary circuit consists of a control relay, emergency stop button, operating status indicator, It is composed of intelligent controller of charging pile and human-computer interaction equipment (display, input and card swiping).
The main circuit input circuit breaker has overload, short circuit and leakage protection functions; the AC contactor controls the on and off of the power supply; the connector provides a charging interface for connecting with electric vehicles, and has a locking device and anti-misoperation function.
The secondary circuit provides "start-stop" control and "emergency stop" operations; signal lights provide "standby", "charge" and "full" status indications; AC smart energy meters for AC charging measurement; human-computer interaction devices provide card swiping and charging Mode setting and start-stop control operation.
