Description

Technical Field

[0001] The present invention relates to the technical field of chargers, in particular to a charger capable of controlling time and timing charging. Background Art

[0002] A charger is a device that converts electrical energy from an AC power source into DC power suitable for use with compatible equipment, while an electric vehicle charger is a charging device for electric vehicles that can meet the charging needs of users.

[0003] However, most of the existing electric vehicle chargers on the market do not have a timing function, so that the electric vehicle battery will continue to receive current after it is fully charged, which may cause the battery charging time to be too long. Long-term use may damage the health of the battery, shorten the battery life, and may even cause battery expansion or thermal runaway, posing a safety hazard and avoiding the waste of electrical energy. In addition, most of the existing electric vehicle chargers on the market cannot detect the changes in the current and voltage output of the charger in real time, so they cannot disconnect the circuit in time when the current and voltage are abnormal. Therefore, unstable voltage and current will cause the battery temperature to continue to rise, accelerate battery corrosion and aging, which may cause battery damage and shorten the battery life.
