Abstract

The invention relates to a pulse type constant current cell float charger and belongs to the electronic technology field. The pulse type constant current cell float charger comprises a trickle resistor, a triode type oscillation unit, a constant current charging unit, a process indicating unit, an ending sampling unit, an interface unit and a load unit, wherein a charging work tube and a standby tube of the constant current charging unit are connected in a constant current mode, so a constant current charging mode is realized. The interface unit is made to generate high-low conversion becauseof output of the triode type oscillation unit, two triodes of the constant current charging unit are controlled, so a pulse charging stop mode is realized, when a cell is fully charged, the ending sampling unit instantly samples, an ending control unit starts, when the constant current charging unit is closed, an ending prompting unit starts, and light indicating and sound prompting are emitted. After the constant current charging unit is closed, the needed maintaining trickle current is provided by the trickle resistor to the charged cell, the triode type oscillation unit line is easy to realize oscillation, the oscillation process is stable, and thereby requirements of the whole line can be satisfied.

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...
