Problems solved by technology
With more and more functions, the power consumption of electronic devices is also increasing, which leads to users needing to charge electronic devices frequently
[0003] In practice, it has been found that frequent charging may lead to rapid aging of the charger, resulting in a short circuit in the charger during the charging of electronic devices
However, the user cannot detect these short circuits in daily use, so that once a short circuit occurs in the charger, it may cause damage to the electronic equipment or the charger, and may even cause a fire in severe cases, which is not conducive to improving the charging process of the charger to the electronic device. security

The embodiment of the invention relates to the technical field of electronic equipment, and discloses a charger and a short-circuit prompting method in a charging process. The charger comprises a control unit, a short-circuit detection unit, a voltage transformation unit and a short-circuit prompting unit, wherein the control unit is used for sending a first voltage transformation signal to the voltage transformation unit when detecting that to-be-charged equipment is accessed; the voltage transformation unit is electrically connected with the power supply and used for transforming the voltageprovided by the power supply according to the first voltage transformation signal to obtain a first voltage and outputting the first voltage to a charging loop of the to-be-charged equipment, whereinthe first voltage is smaller than the lowest charging voltage of the to-be-charged equipment; the short-circuit detection unit is connected to the charging loop in series; and the control unit is also used for acquiring operation data of the short-circuit detection unit under the action of the first voltage, and controlling the short-circuit prompting unit to output short circuit prompting information when determining that the charger is short-circuited according to the operation data. By implementing the embodiment of the invention, the safety of the charger in the charging process of the electronic equipment can be improved.
Description
technical field [0001] The present application relates to the technical field of electronic equipment, in particular to a charger and a short-circuit prompting method during charging. Background technique [0002] With the rapid development of electronic equipment technology, electronic equipment carries more and more functions. With more and more functions, the power consumption of electronic devices is also increasing, thus causing users to frequently charge the electronic devices. [0003] In practice, it has been found that frequent charging may lead to rapid aging of the charger, thus causing a short circuit in the charger during the charging process of the electronic device. However, the user cannot detect these short circuits in daily use, so that once a short circuit occurs in the charger, it may cause damage to the electronic equipment or the charger, and may even cause a fire in severe cases, which is not conducive to improving the charging process of the charger ...
