Battery floating charge apparatus capable of charging and discharging

Abstract

The invention discloses a battery floating charge apparatus capable of charging and discharging, and belongs to the technical field of electronics. The battery floating charge apparatus is composed ofa charging unit, a discharging unit, an interface unit, a pulse unit, a selection unit, a load unit, a process indicating unit, and a double-termination unit. The charging unit, the discharging unitand the pulse unit are under control of the interface unit and form a pulse charging form that is capable of charging and discharging and having a charging time greater than a discharging time. The battery floating charge apparatus provides two terminations, one is termination after a battery is charged and the other is termination after timing and counting arrive in place. The two termination methods are flexibly switched to each other. After the termination of the charging, a trickle resistor provides the required trickle to a to-be-charged battery. The discharging unit is provided with a discharging cut-off switch, which makes charging more flexible. The interface unit allows the charging unit and the discharging unit to generate a correct logic within one pulse period, specifically, ifthe charging unit is on, the discharging unit is turned off, and if the charging unit is turned off, the discharging unit is on, so that the charging unit and the discharging unit do not interfere each other. According to the embodiments of the invention, the battery floating charge apparatus greatly increases the service life of chargers and the to-be-charged battery, 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
