Problems solved by technology

[0002] At present, when some power battery chargers on the market are not connected to the battery, the voltage at the output terminal of the charger will be equal to or higher than the charging voltage of the charger. On the one hand, if the voltage is higher than the safe voltage of the human body, the charger will increase Unsafe factors, on the other hand, the higher output voltage often requires the application of stricter charger certification standards, which increases the difficulty of certification for charger standards

Abstract

The invention provides an intelligent power charger with an automatic power-off protection device. The intelligent power charger comprises a main output voltage acquisition module, a voltage control module and a single chip microcomputer intelligent controller, wherein the charger is controlled through a pulse width modulation chip, has voltage limiting and current limiting functions, and is provided with a switching power supply circuit system with a charging state indicator. Acquired voltage and charging signal are processed by adopting the single chip microcomputer intelligent controller and a voltage control signal is output, so that the intelligent power charger has the advantages of being intelligent, wide in application range, high in reliability and free of maloperation.

Description

technical field [0001] The invention relates to an intelligent power charger with an automatic power-off protection device, in particular to a power battery charger system that realizes different voltage outputs when the battery is not connected and when the battery is connected. Background technique [0002] At present, when some power battery chargers on the market are not connected to the battery, the voltage at the output terminal of the charger will be equal to or higher than the charging voltage of the charger. On the one hand, if the voltage is higher than the safe voltage of the human body, the charger will increase Unsafe factors, on the other hand, a higher output voltage often requires the application of stricter charger certification standards, which increases the difficulty of certification for charger standards. Contents of the invention [0003] In view of the above-mentioned problems in the prior art, the object of the present invention is to provide an int...
