Power polarity active conversion module and single electric vehicle charging pile, power polarity active conversion module consists of relay, first diode and first capacitor, Single electric vehicle charging pile The single electric vehicle charging pile body, power input front terminal for continuous external power supply, power input neutral line terminal for continuous external power supply, power input ground wire terminal for continuous external power supply ground wire, and power polarity active conversion module. The power polarity active conversion module can be used to actively convert the power polarity of the external power input, so that the charging pile body of electric vehicles can be connected to accurate power input polarity, regardless of whether the external power supply is obstructed by the "front and zero line connection" power supply. Tunzi area and the urban and rural areas of the link department due to power supply often found power supply obstruction caused by single booking of electric vehicle charging pile body can not usually part-time probably found safe and disorderly doubt.
Focus control assembly, electric vehicle charging pile layout touchscreen, payment card module, scanning module, collection module, control module, battery module, take the gun control module, switching module, charge record module, battery led module, touch screen placed by the board, box, screen, placed board box with screen continuously, Touch screen with a credit card payment module, scanning module, a credit card payment module, scanning module through gathering module and control module, beneficial result, equipped with charging record module, frequency superposition of record module through preferential record full charge of the module, the module and battery protection module, can record the past with the card or with car charge record, Charging times accumulated to a certain number of preferential charging, and will rely on the past charging quantity, the next charging quantity is given to initiate, to protect the battery of the electric car.
Electric vehicle charging pile electric impede imitation system, its characteristic is that the system contains the electric vehicle charging pile, programmable switching power supply, charging interface obstruction of imitation, the second set of control system, in this, programmable switching power supply configuration in the input end of the electric vehicle charging pile, charging interface impede imitation device configuration on the output of the electric vehicle charging pile, Secondary data input ports division continued to set control system programmable switching power supply and charging interface obstruction of imitation, the second set of control system of data acquisition to differentiate port configuration in programmable switching power supply, electric vehicle charging pile and interfere with the ongoing pathways in the imitation of charging interface point of each link, to collect and monitor described link point of operation condition, Dealt with the existing technology shortage of electric vehicle charging pile in a variety of dark and toxic environment of the real imitation search, can not be electric vehicle charging pile of the real function and lack of exemplification of the attempt, and further, should be the user's electric vehicle in the application process to bring safety problems.
