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

Abstract

The invention relates to a parallel floating charger capable of appropriately charging and stopping, and belongs to the technical field of electronics. The parallel floating charger comprises a process indication unit, a P-type parallel charging unit, an interface unit, a pulse unit, a dual-selection ending unit, a discharging unit, a load unit and a trickle resistor. A charging circuit difficultto damage is achieved by a few active pieces, two symmetric charging circuits are arranged in the P-type parallel charging unit, the power is improved, the P-type parallel charging unit is difficult to damage, a diode in each charging circuit is connected in a constant-current mode and is matched with the pulse unit and the interface unit to form pulse constant-current charging, two modes of ending after full charging of the battery and timely ending are arranged in measure, the switching is flexible and convenient, sound is reminded after ending, and a required trickle current is provided fora charged battery by the trickle resistor. After implementing the parallel floating charger, the charging time and charging stopping time of the charged battery can be flexibly adjusted, different types of charged batteries are adapted, the lifetime of the charger and the charged battery is prolonged to the greatest extent, and environmental friendliness of society is achieved.

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...
