Charger control method based on electric vehicle state

Abstract

The invention discloses a charger control method based on an electric vehicle state. The charger control method comprises the steps that after an electric vehicle is connected with an electric supplythrough a charger, the current temperature of an electric vehicle battery which is connected with the charger is obtained, and after the electric vehicle is connected with the electric supply throughthe charger, the current electric quantity of the electric vehicle battery which is connected with the charger is obtained; and the current temperature of the electric vehicle battery is compared witha preset temperature threshold value, according to a comparative result, an audio and video alarm is sent out, and / or an alert notification is sent to a pre-arranged intelligent terminal, and / orconnection of the electric vehicle which is connected with the charger and the electric supply is cut off, the current electric quantity of the electric vehicle battery is compared with a preset electric quantity value, and according to a comparative result, connection of the electric vehicle which is connected with the charger and the electric supply is cut off.

Description

technical field [0001] The invention relates to the technical field of electric vehicle chargers, in particular to a charger control method based on the state of an electric vehicle. Background technique [0002] The current electric vehicle chargers used by people do not have the function of automatic power-off. People habitually directly pull out the plug end of the electric vehicle after the electric vehicle is fully charged, and will not actively pull out the electric vehicle charger from the socket. At this time, there is still a weak current in the electric vehicle charger, which is very dangerous. Once the circuit of the charger has problems such as aging and short circuit, it is very easy to cause major disasters such as fire. The charging time is 7-8 hours, that is to say, the charger is in the waiting state for more than 10 hours, which causes unnecessary waste of electric energy and has certain potential safety hazards. Contents of the invention [0003] Based ...
