In practical situations, when the storage battery G1 stores more power (i.e., when the solar panel G is illuminated by more power), the power supply with a voltage of more than 12V (the storage battery G1 and the solar panel G have more power, and the output voltage of the storage battery G is higher than 12V when the storage battery G is in no-load or in no-load) is reduced in voltage and limited by the resistor R1, and then the base voltage of the NPN transistor Q1 is higher than 0.7V, so that the NPN transistor Q1 turns on the collector to output a low level to the negative power input terminal of the relay K1, and further, the relay K1 is powered to pull in two control power input terminals and two normally open contact terminals thereof to be respectively closed, and the two control power input terminals and the two normally closed contact terminals are opened. When the storage battery G1 has less storage (namely, after the subsequent electric vehicle uses more solar panels and the storage battery G1 outputs electric energy for charging), the voltage of a power supply below 12V is reduced and limited by the resistor R1, then the base voltage of the power supply entering the NPN triode Q1 is lower than 0.7V, then the NPN triode Q1 is cut off, the relay K1 loses power and does not attract the two control power supply input ends and the two normally open contact ends to be respectively opened, and the two control power supply input ends and the two normally closed contact ends are closed. Because, power output end 3 and 4 feet of power inverter U4, fill two normally open contact ends and two normally closed contact ends of 220V power input line and relay K1 of electric pile body and connect through the wire respectively, two control power input ends of relay K1 and two control power input ends of relay K connect through the wire respectively, two contact ends of relay K and the total power input end of filling electric pile body U3 connect respectively, the ethernet panel G fully produces the electric energy, when battery G1 stores more electric energy, solar panel G can cooperate battery G1 to charge for electric vehicle battery through power inverter U4 etc. battery, can automatic control commercial power 220V power when battery G1 electric energy reduces and will exhaust and charge for electric vehicle's battery.

When a charger needs to charge the vehicle storage battery, the charger inserts the charging gun 101 of the charging pile into the storage battery charging socket of the automobile, and due to the blocking of the charging socket, a detection head of the photoelectric switch U2 is blocked by an object before, 3 pins of the detection head can output high level to enter the positive power input end of the relay K, and then the relay K is in an electric pull-in state, and the control power input end and the normally open contact end of the relay K are closed. Because two contact ends of relay K and the total power input end that fills electric pile body U3 connect respectively, so when charging, fill electric pile body U3's total power input end and can receive the electricity, solar cell panel or commercial power 220V power can be through filling the main control board of electric pile body, charging source board etc. and charge for vehicle storage battery (after the rifle that charges inserts the socket that charges, the person that charges sweeps a yard through the cell-phone and charges).

As shown in fig. 1, 2, and 3, after the wireless transmitting circuit (only 15 ma) is powered on, the time switch U5 outputs 2 seconds of power to the pins 1 and 2 of the wireless transmitting circuit module U6 every 3 seconds under the action of the power output time of pins 3 and 4 set by the circuit technician therein, so that the wireless transmitting circuit module U6 is powered on every 3 seconds, and since the two contacts of the first wireless signal transmitting button S1 of the wireless transmitting circuit module U6 are connected together by the wires in advance, the wireless transmitting circuit module U6 sends a first wireless close signal every 2 seconds every 3 seconds. In the wireless receiving circuit, before use, a driver turns on the power switch SK, so that the wireless receiving circuit module U7 is in a power-on working state, a vehicle drives into the charging pile body within 500 meters, after the field charging pile wireless transmitting circuit module transmits a first path of wireless closing signal, at the moment, the wireless receiving circuit module U7 receives the first path of wireless closing signal, 4 feet of the wireless receiving circuit module output high level, the high level is subjected to voltage reduction and current limitation through a resistor R2 and enters the base electrode of an NPN triode Q2, then the NPN triode Q2 conducts a collector and outputs low level to enter the negative power input end of a buzzer B, and the buzzer B is powered to send out loud prompt sounds (sounds every 3 seconds and 2 seconds), so that under the actual condition, the vehicle driver can visually know that the charging pile is nearby within 500 meters and timely keeps the charging pile body in the roadside area, so that the vehicle can be charged as soon as possible (the charging pile body is not found, buzzer B stops when the sounding, representing that the vehicle misses the charging pile body at this moment, and the driver can turn back to find the charging pile body again as required). Through the combined action of the circuits and the mechanisms, the novel charging pile body can be automatically switched to be complete machine power supply between a solar power supply system and commercial power under the action of a switching circuit in application, and can be used for charging vehicles at high power, and when no vehicle is charged under the action of a control circuit, a main control board and a charging power supply board in the charging pile body are all in a power-off state, so that the service life of related parts can be prolonged on the premise of achieving the purpose of energy conservation; the wireless transmitting circuit can transmit wireless positioning signals at intervals of a certain time, a driver with a wireless receiving circuit can know the approximate position of a nearby charging area at the first time, and then a specific charging pile position is found in as short a time as possible to charge the vehicle storage battery, so that convenience is brought to the driver who cannot use a corresponding mobile phone APP skillfully and does not install the APP, the number of times for the driver who installs the corresponding mobile phone APP to check a screen can be reduced, and a good safety effect is achieved; because increased intelligent function, can improve product market competition for filling electric pile manufacture factory and provide powerful technical support.
