Abstract

An intelligent charging system of an electric car comprises a single-chip microcomputer, an outage control circuit, a charging control circuit and a voltage detection circuit, wherein the single-chip microcomputer controls the outage control circuit, the charging control circuit and the voltage detection circuit. The single-chip microcomputer serves as a control center, the outage control circuit, the charging control circuit and the voltage detection circuit are connected together to form a closed-loop control circuit, and by the adoption of relay switch control and utilization of a capacitance charge-discharge principle, an automatic closing and turn-off control circuit is formed. Power is supplied or interrupted effectively as needed.

Description

technical field [0001] The invention relates to the field of electric vehicle charging, in particular to an electric vehicle intelligent charging system. Background technique [0002] With the development of electric vehicles, there are more and more applications, but the electric vehicle will not automatically cut off the power if the charging device is not removed after it is fully charged. The charging state is trickle charging. Failure to cut off the power automatically like this will result in a waste of electric energy, excessive charging time will damage the service life of the storage battery, and charging the heating bottle for a long time will cause an explosion. [0003] In response to this situation, the existing solution is to use the principle of capacitor discharge, preset the RC discharge cycle, and use a self-resetting switch. Press the switch to charge the capacitor, release the switch to start discharging, and then use the relay switch to cut off the pow...
