The invention has the beneficial effects as follows: 1, adopt the aluminium alloy compression casting housing, the comprehensive waterproof of fuselage, the indoor and outdoor all can be used; 2, improve the useful life of equipment: the steady ripple disable of charging current, the compatible lead-out terminal of high density, socket adopts Universal Socket, contacts more reliably, and the plug life-span is strengthened, and is applicable to the ac plug of most countries; 3, the charging modes of diversification: according to different occasions, be set at public place pattern and home mode, home mode adopts regularly charge mode by the program control button control time; The public arena pattern is swiped the card by machine for punching the card, calculates consumption electric weight charge mode; 4, perfect safety protection function: do not swipe the card, the output of charging pile no-voltage has short circuit, electric leakage, overvoltage, under-voltage protection function; 5, rational in infrastructure, safe and reliable, has compatible output interface reliably, the charging current that is not more than 32A can be provided, and output current is big, the automaticity height, defencive function is complete, and have clocking capability, and can show electric power, output voltage, charging interval and charge capacity simultaneously, reliable and stable; 6, charging operations is simple, as long as the user connects input power cord, inserts charging plug and gets final product power-on, pulls out plug-in power pack and breaks automatically inside after 2 minutes, can finish charging automatically by inner testing circuit, need not staff on duty; 7, this charging pile can be made console mode or the wall-hanging public places such as parking lot, bus stop, road limit that are placed on, and this electric vehicle alternating-current charging pile is applicable to that various is the charging work of the various vehicles such as EV, HEV field vehicle, terrain vehicle of power with the storage battery.

Description of drawings

The invention will be further described below in conjunction with accompanying drawing.

Fig. 1 is the present invention's electricity theory diagram;

Fig. 2 is the embodiments of the invention circuit diagrams.

Embodiment

As shown in Figure 1, a kind of electric vehicle alternating-current charging pile has a control circuit, and control circuit comprises controller, is connected the accounting module that is used to calculate the consumption electric weight with controller; Be connected the display that is used to show information such as charging voltage, electric power with controller; Be connected the relay that is used as protection switch with controller; Be connected the meter power model that is used to detect input supply voltage, size of current with controller; The outside 220V AC power of meter power model input termination, output is connected with relay, and relay output 220V voltage charges a battery; Above-mentioned control circuit is installed in the housing.

As shown in Figure 2, controller adopts the ATMEGA16 single-chip microcomputer, and display adopts LCD, is used for display voltage, reaches institute's power consumption; When reaching the consumption electric weight, the charging pile output cuts off the power supply automatically.Accounting module adopts number card machine or program control button, and 25,26 pin of machine for punching the card and ATMEGA16 single-chip microcomputer are connected, and just can allow charging pile work by swiping the card; Charge by swiping the card in public.The ATMEGA16 single-chip microcomputer has been set program, can control the charging interval by the program control button on the ATMEGA16 single-chip microcomputer in family.1,2,3,9,10,12,13,14,15,16,40,41,42,43,44 pin of LCD and ATMEGA16 single-chip microcomputer are connected.The meter power model adopts meter power chip ADE7755, and 30,31 pin of meter power chip ADE7755 and ATMEGA16 single-chip microcomputer are connected, and 24 pin of ATMEGA16 single-chip microcomputer are connected with relay.When faults such as overvoltage, electric leakage, short circuit occurring, the ATMEGA16 single-chip microcomputer is protected by the control relay power cutoff.
