Overcharge prevention device of electric vehicle charger based on Internet of Things

Abstract

The invention relates to the technical field of related equipment of Internet of Things, and discloses an overcharge prevention device of an electric vehicle charger based on Internet of Things. The overcharge prevention device comprises a charging pile and a charging plug, an electromagnetic soft iron is fixedly connected to the interior of the charging pile, a conductive wire is arranged on thesurface of the electromagnetic soft iron, and a sliding groove is formed in the upper side of the electromagnetic soft iron. A permanent magnet is slidably connected into the sliding groove, a springis fixedly connected to the top of the permanent magnet, a connecting groove is fixedly connected to the left side of the permanent magnet, a connecting rod is arranged on the left side of the permanent magnet, and a fixing pile is rotatably connected to the surface of the connecting rod. According to the overcharge prevention device of an electric vehicle charger based on Internet of Things, through cooperative use of the electromagnetic soft iron, an electric lead, the sliding groove, the permanent magnet, the spring, the connecting groove, the connecting rod, a fixed pile, a dielectric rod,a limiting groove negative plate, a positive plate and a switch, the effects of reflecting the electric quantity during charging and automatically powering off when the electric vehicle charger is fully charged are achieved.

Description

technical field [0001] The invention relates to the field of equipment related to the Internet of Things, in particular to an overcharge prevention device for an electric vehicle charger based on the Internet of Things. Background technique [0002] With the rapid development of the Internet of Things technology, more and more fields have applied the Internet of Things. For example, charging piles for charging electric vehicles use the Internet of Things technology to realize online payment and then open the charging function. [0003] However, this type of charging pile cannot judge whether the battery of the electric vehicle is full, and the power supply cannot be cut off in time to stop charging when the battery is full, which may cause overcharging of the battery of the electric vehicle, thereby causing damage to the battery of the electric vehicle and affecting the service life of the battery. Charging and charging piles will continue to charge, causing waste. [0004]...

AI Technical Summary

Problems solved by technology

[0006] Aiming at the deficiencies of the prior art, the present invention provides an overcharge prevention device for an electric vehicle charger based on the Internet of Things, which has the ability to respond to the electric quantity when the electric vehicle is charging, and can automatically cut off the power when fully charged, preventing overcharging and protecting the battery , the advantage of not causing waste, solves the problem that the charging pile cannot judge whether the electric vehicle is full of electricity, and the power supply cannot be cut off in time to stop charging when the electricity is full, which may cause overcharging of the battery of the electric vehicle, thereby causing damage to the battery of the electric vehicle and affecting The service life of the battery, and charging piles will continue to charge, resulting in a problem of waste
