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 a universal nickel-cadmium nickel-metal hydride rechargeable battery charger, which comprises a main output voltage acquisition module, a voltage control module and a single-chip microcomputer intelligent controller. The charger is controlled by a pulse width modulation chip and has the voltage limiting function and the current limiting function. Meanwhile, the charger is provided with a switching power supply circuit system having the charging state indication function. According to the invention, due to the arrangement of the single-chip microcomputer intelligent controller, collected voltage and charging signals are processed, and a voltage control signal is outputted. The charger has the advantages of intellectualization, wide application range, high reliability,no wrong action and the like.

Description

technical field [0001] The invention relates to a universal nickel-cadmium-nickel-hydrogen rechargeable battery charger, 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 a kind of...
