Hybrid type dual-finishing type floating charging apparatus

Abstract

The invention discloses a hybrid type dual-finishing type floating charging apparatus, and belongs to the technical field of electronics. The hybrid type dual-finishing type floating charging apparatus comprises a constant current source, a silicon controlled rectifier charging unit, a discharging unit, an interface unit, a pulse unit, a dual-selection finishing unit, a voice control unit, a process indicating unit, a load unit and a trickle resistor; the constant current source provides a constant current for the silicon controlled rectifier charging unit, so that constant current charging can be performed; the pulse unit controls the interface unit and the discharging unit, and the interface unit controls the silicon controlled rectifier charging unit, so that a pulse form is formed; inone pulse period, charging and discharging coexist; by virtue of pulse, duty ratio adjustment is also performed, so that the charging time is longer than the discharging unit; in the measures, two finishing ways of finishing after the battery is fully charged and finishing when timing is completed are included and can be switched flexibly and conveniently; sound prompting is given out in finishing; and the trickle resistor provides the required trickle for the charged battery to realize scientific charging and maximum discharging for the battery, thereby maximizing the service lives and capacities of the charger and the charged battery.

Description

technical field [0001] It belongs to the field of electronic technology. Background technique [0002] Our company applied for a series of security products some time ago, and this product must have a backup battery, otherwise, when there is no mains power, the security function will become a fake, and when there is no mains power, it may be the peak of security accidents when. So a backup battery is required. And the performance of the backup battery is directly related to the overall performance. [0003] But the backup battery must be charged and maintained, and the scientific maintenance of the backup battery is directly related to the life and capacity of the backup battery. Some sources believe that batteries are often not worn out, but damaged due to improper charging. Batteries in security equipment are special-purpose batteries, which have special requirements for volume and capacity, and are more demanding than general products. [0004] The reason why the mos...

Problems solved by technology

[0004] The reason why the most scientific charging has not been realized is that the current products either only use DC to charge the battery, but do not use a better method, such as constant current charging; or although they can be charged with a constant current source, However, there are still some conveniences in use, or it is not scientific enough on the line, etc., so it should be enriched and developed
