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

Abstract

The invention relates to a constant current type cell charging device and belongs to the electronic technology field. The device comprises a trickle resistor, a constant current charging unit, an ending promoting unit, an ending sampling unit, an ending control unit and a load unit. For the constant current charging unit, a charging work tube and a standby tube are connected in a constant currentmode, so a constant current charging mode is realized, and the two tubes are connected in a special parallel mode to charge a charged cell; during common use, only the charging work tube works, the standby tube is dormant, after the charging work tube is damaged, the standby tube instantly works instead of the charging work tube to charge the charged cell, after the cell is fully charged, the ending sampling unit instantly samples, the ending control unit starts, when the constant current charging unit is closed, the ending prompting unit starts, and light indicating and sound prompting are emitted. After the current charging unit is closed, the needed maintaining trickle current is provided by the trickle resistor for the charged cell, scientific maintenance for the cell is carried out, service life of the charger is substantially improved, and the rejection rate of chargers is reduced.

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...
