Alarm anti-theft electric vehicle charger

Abstract

The invention discloses an anti-theft electric vehicle charger capable of alarming, which comprises a circuit board and an alarm control circuit, wherein the circuit board converts alternating current into low-voltage direct current and charges an electric vehicle. The circuit board is provided with a direct current output end and a charging plug connected to the direct current output end. The alarm control circuit is connected between the direct current output end and the charging plug of the circuit board. The alarm control circuit can operate at a charging state and a non-charging state. The alarm control circuit can give out an alarm when connection between the charging plug and a charging port of the electric vehicle is broken at the non-charging state. The alarm control circuit can give out an alarm when connection between the charging plug and the charging port of the electric vehicle is broken in the charging process or when charging is completed at the charging state. The anti-theft electric vehicle charger disclosed by the invention has the characteristics of simplicity, convenience, safety and reliability, realizes combination of a charger and an alarm, can have a function of being safe and theft preventing while charging the electric vehicle, and realizes integrated theft prevention of the electric vehicle and a storage battery.

Problems solved by technology

However, there have been frequent cases of electric vehicle theft. Due to the "consumable" and "universal" characteristics of electric vehicle batteries, "stealing batteries" is more common now. Although the economic loss is not very large, it brings The inconvenience and annoyance are obvious, the victims are angry and helpless, and lack effective countermeasures

[0003] Generally, the alarms installed on electric vehicles are mostly of the "vibration type" principle, and there are many "false alarms" in actual use, which affects the precise display of its anti-theft effect

Some other alarms have different working principles, but they often have problems such as high false alarm rate, low reliability, and inconvenient installation and use.
