Abstract

The invention discloses a pulse-type battery floating charger, and belongs to the technical field of electronics. The floating charger consists of a constant current unit, a floating charging unit, asound control unit, an interface unit, a pulse unit, a timing end unit, a load unit and a process indication unit. The floating charging unit, the pulse unit and the interface unit jointly form a pulse charging mode which can achieve charging and stop charging, wherein the charging time of the pulse charging mode is longer than the time when the charging is stopped. A current required by the floating charging unit is provided by the constant current unit, so the floating charger achieves the constant current charging. The timing end unit employs a mode of timing counting, and stops the charging when the set time arrives. The floating charger is especially suitable for some batteries to be activated. After a final output end of a counter outputs a high voltage, the sound control unit is started, and sends out voice to give a prompt to a user. A trickle resistor is used for providing a required trickle current for a charged battery. After implementation, all units are scientifically connected, and achieve the comprehensive utilization. The floating charger is simple in circuit, and is high in reliability.

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...
