With source filtering effect of electric vehicle charging pile, credit card, master device, electric meter charging pile, touch device, inverter modules and rechargeable spear, charging pile master device containing rechargeable mastering the unit and the inverter module, charging control unit for electric meter, electricity meter touch continuous charging spear and inverter module control inverter module connected to the touch and charge between the spear head, The electricity meter is also continuous phase line and zero line, charging pile master unit electricity meter and card reader to complete charging pile charging, inverter module master inverter module to complete electric vehicle charging pile unit power factor and low harmonic operation. The inverter module controller uses the double zero proportional resonance controller to realize the high precision harmonic current controller. Electric vehicle charging pile has harmonic control and reactive power compensation functions, without the need for external active power filter, and the compensation point is located at the back end of the electricity meter, which reduces the meter charging deviation caused by harmonic current.
Electric vehicle charging pile multi gun active identification error correction system, skills and charging pile. The light receiving module absorbs the charging gun number, user message and order message selected by the user; The message distribution and disposal module gets classified messages from the messages extracted. The module of active identification and correction classifies classified messages and establishes classified message table; The active identification error correction module verifies whether the charging gun number of the reaction lamp is the same as the charging gun number selected by the user; If the charging gun number is configured as locked state; If it is different, it will actively mediate and represent the real continuous charging gun number, and configure the real continuous charging gun number as the locked state. Completed the arrangement of a multi-gun charging gun everywhere, casually plug and pull master, useful to deal with the user will charge the gun back to the wrong position, choose the wrong gun, can not charge, deduct the wrong fee, can not stop charging, can not get out of the trouble.
Charging pile for electric vehicle with cage type and static conduit, charging host, charging master continuously communicating with charging host, total electric quantity metering unit, multiple electric quantity metering units continuously communicating with charging master and corresponding to multiple electric quantity metering units, Its feature lies in charging control device in multiple charging unit of one or more until the number of one or more of the same by charging equipment charging interface, achieve sustained lights and charging construction, and the message through to the construction of charging based on the obtained power metering unit, charging unit to be held a charging equipment. The charging pile can improve the single charging pile obedience, thrifty settlement of the old, reduce the settlement of the garden request
