Wireless induction charging pile system

Abstract

The invention discloses a wireless induction charging pile system and belongs to the technical field of automobile charging. The wireless induction charging pile system comprises a storage module, anLCD (Liquid Crystal Display), a printing module, a payment module, a microcontroller, a wireless communication module, a power circuit and an alarm pulse luminescent tube, wherein the microcontrolleris connected with a single-phase electric power metering chip; the power circuit is electrically connected with an AC storage battery by virtue of an active power filter and a harmonic detection module; the single-phase electric power metering chip is connected with a disc-like induction transmitting coil; and an infrared emission module, the wireless communication module, a strip-shaped inductiontransmitting coil, the disc-like induction transmitting coil and the alarm pulse luminescent tube form a multipath wireless induction charging system together. The wireless induction charging pile system disclosed by the invention has the advantages of being simple in structure, low in cost and the like, can be directly used for charging mobile phones and other equipment by using the wireless induction module, is convenient to use and high in cost performance, and can achieve effects of filtering fundamental reactive current, negative-sequence current, zero-sequence current and harmonic current in load current and avoiding the influences of zero-sequence leakage errors.

Description

technical field [0001] The invention relates to a charging pile system, in particular to a wireless induction charging pile system, which belongs to the technical field of automobile charging. Background technique [0002] The charging pile is a charging station for electric vehicles. It looks like a parking stopwatch. Generally, one charging pile can charge two cars at the same time. The charging time from no power to full is 6 to 8 hours. The charging pile can realize timing and power metering. It can be used as a terminal for citizens to purchase electricity. At the same time, in order to improve the efficiency and practicability of public charging piles, the function of charging multiple piles and charging electric bicycles will be added in the future. Up to now, most of the charging stations for electric vehicles in China It is limited to electric buses or internal group vehicles, and has not yet built a service network of charging stations for different users. At prese...

Problems solved by technology

[0003] The main purpose of the present invention is to provide a wireless induction charging pile system that can realize human-computer interaction, is more convenient to use, has higher cost performance, and can directly charge mobile phones and other devices with a wireless induction module, so as to solve the problem of the current electric vehicle charging pile network. The side harmonic content is relatively large, which can filter out the fundamental reactive current, negative sequence current, zero sequence current and harmonic current in the load current, leaving only the fundamental positive sequence active component, avoiding the zero sequence leakage error Impact
