Problems solved by technology

[0003] However, due to the small difference between the chargers of electric vehicles, many users worry that their own charging equipment will be stolen by others for charging, which will bring unnecessary losses to users.
This smart charger uses a special socket and charger. The special charging socket only allows charging with its own matching charger. When a normal charger or electric device is plugged in, the socket will automatically cut off the power, making it unusable

Embodiment 1

[0034] Embodiment 1: as figure 1 , 2、As shown in 3, connect two infrared photoelectric sensors G1, G2 (MOCH22A, LA-H42B6) to the jack of the socket. When the plug is inserted, the infrared propagation path is cut off by the plug, and the infrared receivers B1 and B2 cannot receive it. The signals sent by the infrared emitters L1 and L2 are in a high resistance state, and the triodes Q1 (S8050) and Q2 (S8050) (comprising a Darlington tube) are in an off state. In this way, pins 1 and 2 of the integrated block CD4011 of the NAND gate is low level, pin 3 outputs high level, and the output current of pin 3 passes through resistors R5 and C1 to make the triode Q5 (D669) and Q6 (D669) conduct current from the collector to the emitter, and the electromagnetic relay KA2 is attracted. The 220V AC is connected to the output terminal of the socket and the 12V DC power supply 2 through the K2 and K3 keys of the electromagnetic relay KA2 (SONGLE SRE-12DC-SL-2C). Since the bases of the tra...

Embodiment 2

[0037] Embodiment 2: as figure 2 , 4 As shown, the double flash circuit in embodiment 1 is made up of ceramic capacitor C2 (104Pf, 1000V), resistor R10 (20KΩ), adjustable rheostat R11 (50K), electrolytic capacitor C6 (470μf), and integrated block NE555. When the pulse generated by the basic circuit is replaced, the embodiment 2 can be obtained; the 3-pin output pulse signal of NE555 is amplified by the triode Q11 and Q12 to make the electromagnetic relay KA5 pull in, K5 conducts, and the wireless signal transmitter sends a conduction to the socket signal; adjusting the size of the variable resistor R11 can adjust the frequency of the pulse signal.

Abstract

The invention discloses an intelligent charging system, which comprises a socket part and a charger part. The socket part comprises a direct-current voltage-stabilizing power supply A, a three-end voltage stabilizer A, a non-gate integrated block, a direct-current voltage-stabilizing power supply B, a signal receiver, an infrared photoelectric sensor A and an infrared photoelectric sensor B. The charger part comprises a direct-current voltage-stabilizing power supply C, a charging module and a signal emitter. The signal receiver is matched with the signal emitter. According to the invention, aspecific-frequency signal emitter and a signal receiver, matched with each other, are additionally arranged. When a charger matched with the signal emitter is inserted in the receiver, the signal receiver in the socket receives a conduction signal and supplies power to a charging circuit. Therefore, the specificity of different signals is skillfully utilized. The economic loss caused to the userdue to the fact that the charger is stolen can be effectively avoided. The intelligent charging system has a considerable practical value and a potential market popularization value.

Description

technical field [0001] The invention relates to the field of charging equipment, in particular to an intelligent charging system. Background technique [0002] Electric bicycles have been favored by low- and middle-income groups in cities for their cheap, convenient, and environmentally-friendly functional advantages. From the research and development of electric bicycles in China to the market launch in small batches in the mid-1990s, to the production and sales since 2012, it has been showing a momentum of substantial growth year by year. Due to strong demand, China's electric bicycle market has maintained leapfrog growth in recent years. Statistics show that the national output in 1998 was only 54,000, and in 2002 it was 1.58 million. By 2003, the output of electric bicycles in China had reached more than 4 million, ranking first in the world. The average annual growth rate from 1998 to 2004 exceeded 120%. . In 2009, the output reached 23.69 million units, a year-on-ye...
