Intelligent electrical vehicle charger with communication function and alarm function

Abstract

The invention discloses an intelligent electrical vehicle charger with a communication function and an alarm function. The intelligent electrical vehicle charger mainly comprises a single chip microcomputer, an input end, a charging circuit, a switch unit, a detection unit and an output end, wherein the input end, the charging circuit, the switch unit, the detection unit and the output end are sequentially connected with one another; the single chip microcomputer is respectively connected with the charging circuit and the detection unit; the switch unit comprises a manual switch and a time-delay relay; the manual switch is respectively connected with the charging circuit and the detection unit; the time-delay relay is respectively connected with the charging circuit and the detection unit; and the single chip microcomputer is also respectively connected with a communication unit, an alarm unit and a man-machine interface. According to the intelligent electrical vehicle charger, the charging starting time can be independently selected according to the user requirements; and the intelligence electrical vehicle charger can be independently powered off after fully charging, so as to realize intelligent control. Meanwhile, one manual switch is added; the manual switch can be adopted by the user according to the requirements; and the intelligent electrical vehicle charger can immediately charge and stop charging, so that the intelligent electrical vehicle charger is relatively flexible and convenient to use; and by a dual-switch mode, the charger can continue to work when the other switch is damaged, so that the stability of the charger is increased.

Description

technical field [0001] The invention relates to a charger, in particular to an intelligent electric vehicle charger with a communication function and an alarm function. Background technique [0002] Due to the flexibility, convenience and travel cost savings of electric vehicles, more and more people choose to travel by electric vehicles. It can not only avoid road congestion caused by cars, but also save the cost of traveling by car. However, due to technical limitations, electric vehicles will not be used for a long time after being fully charged, so the charging frequency is very frequent. Moreover, due to the long charging time of electric vehicles, the phenomenon of overcharging is often caused, which seriously damages the service life of electric vehicle batteries. [0003] In the existing technology, most electric vehicle chargers are manually charged or powered off according to user needs. Generally, they are charged before going to bed, and then powered off the ne...

However, due to technical limitations, electric vehicles will not be used for a long time after being fully charged, so the charging frequency is very frequent

Moreover, due to the long charging time of electric vehicles, overcharging often occurs, which seriously damages the service life of electric vehicle batteries.

[0003] In the existing technology, most electric vehicle chargers are manually charged or powered off according to user needs. Generally, they are charged before going to bed, and then powered off the next day. The interval is too long, or the user Forgot to turn off the power, etc., these reasons will cause overcharging
