Ending dual-selection low carbon environmental protection float charger

Abstract

The invention relates to an ending dual-selection low carbon environmental protection float charger and belongs to the electronic technology field. The ending dual-selection low carbon environmental protection float charger comprises a process indication unit, a P-type charging unit, an interface unit, a pulse unit, a dual-selection ending unit, a discharging unit, a load unit and a trickle resistor, wherein the P-type charging unit is in a constant current mode, after the P-type charging unit is matched with the pulse unit and the interface unit, pulse type constant current charging is realized. According to the ending dual-selection low carbon environmental protection float charger, two ending modes are included, one ending mode is utilized after a cell is fully charged, the other endingmode is utilized after timed counting is in place, the two modes can be flexibly switched and are convenient, after ending, the needed trickle current is provided by the trickle resistor for a charged cell, after enforcement, the charging and charging stop time of a charged power source can be flexibly adjusted, adaptation to different types of charged cells is realized, charging ending selectionmodes are added, for first-time charging cells, the timed ending mode is added, the time is accurate, setting the prompting time is not needed, the circuit is simple, production debugging is easy, and the float charger is suitable for micro enterprise production.

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
