Pulse floating charger having backup

Abstract

The invention discloses a pulse floating charger having a backup, and belongs to the technical field of electronics. The floating charger is composed of a floating charge unit, a discharging unit, a sound control unit, an interface unit, a pulse unit, a selection unit, a computing unit, a voltage limiting starting unit, a load unit, a process indicating unit, a termination unit. The floating charge unit, the discharging unit and the pulse unit are under control of the interface unit, such that the floating charge unit and the discharging unit generate a correct logic and forms a pulse charging form that allows charging and discharging and has a charging time longer than a discharging time. Since the floating charge unit and the discharging unit both have a backup, which ensures the reliability of the floating charge unit and the discharging unit. The pulse floating charger provides two termination, and one is termination after a battery is charged and one is termination after timing and counting arrives in place. The two termination can be flexibly switched to each other. After the termination of the charging, the sound control unit is started so as to provide an alert to users. According to the embodiments of the invention, the pulse floating charger can charge a to-be-charged battery in a scientific manner, improves maintenance, prolongs the service life of the to-be-chargedbattery, and reduces discard rate.

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
