Timing ending type pulse controlled floating charger

Abstract

The invention discloses a timing ending type pulse controlled floating charger, and belongs to the field of electronic technique. The timing ending type pulse controlled floating charger consists of atrickle resistor, a constant current unit, a charge unit, an interface unit, a pulse oscillating unit, a timing ending unit, a voice control unit, a load unit and a process indicating unit; the constant current unit is used for providing constant current for the charge unit, and thus constant current charging is realized; however, under the control of the interface unit, a charging and charging-stop pulse charging mode of the charging unit and the pulse oscillating unit is formed, and the charging time is longer than the charging-stop time, so that scientific charging for a charged battery isrealized, and the rejection rate is reduced; a timing ending type is adopted, a timer in the timing ending unit is low in static power consumption and wide in operating voltage range; after timing isended, the interface unit and the voice control unit are turned on, voice reminding is emitted while the charge unit is turned off, and simultaneously, the trickle resistor is used for providing sustaining trickle for the charged battery. The timing ending type pulse controlled floating charger is simple in circuit and easy to produce and debug, and is extremely applicable for microenterprise 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
