Floating charging device capable for appropriately allocating charging time and discharging time

Abstract

The invention relates to a floating charging device capable for appropriately allocating charging time and discharging time, and belongs to the technical field of electronics. The floating charging device comprises a process indication unit, a floating charging unit, a discharging unit, an interface unit, a pulse unit, a dual-selection ending unit, a discharging unit, a load unit and a trickle resistor. A P-type charging unit is connected in a constant-current mode and is matched with the pulse unit and the interface unit to form pulse constant-current charging, a charging mode with charging time longer than discharging time is formed within a pulse period, and the maintenance of a charger and a charged battery is facilitated. Two ending modes are achieved, one of the ending modes is in away that ending is achieved after full charging of the battery, the other ending mode is in a way that ending is achieved after timing countering is in place, the two modes are flexible and convenientto flexible, a required trickle current is provided for the charged battery by the trickle resistor after ending, all units are scientifically connected after implementation, integral utilization isachieved, the charging time and the charging stopping time of a charged power supply can be flexibly adjusted, and different types of charged batteries are adapted.

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
