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

Embodiment Construction

[0017] Attached below figure 1 -2, describe the preferred embodiment of the present invention in detail:

[0018] A universal nickel-cadmium-nickel-hydrogen rechargeable battery charger for a power battery charger of the present invention realizes a power battery charger system with different voltage outputs when the battery is not connected and when the battery is connected, which includes the acquisition of the main output voltage Module 1, regulated power supply module 2, voltage control module 3 and single-chip intelligent controller 4. The inside of the single-chip intelligent controller 4 contains a control algorithm program, which provides a stable DC operating voltage to U2 in the single-chip intelligent controller through the output terminal of U4 in the stabilized power supply module 2, and the program in U2 starts to run, system initialization, configuration and The two pins connected to resistors R3 and R6 in the main output voltage acquisition module are in analo...

Abstract

The invention provides a universal nickel-cadmium Ni-MH rechargeable battery charger, and the charger comprises a main output voltage collection module, a voltage control module and a single-chip microcomputer intelligent controller. The charger is controlled by a pulse width modulation chip, and has effects of voltage limiting and current limiting, and is provided with a switching power circuit system with a function of charging state indication. Because the single-chip microcomputer intelligent controller is employed for processing the collected voltage and charging signal and outputting a voltage control signal, the charger is intelligent, is wide in application range, is high in reliability, and has no misoperation.

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...
