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 floating charger capable of pulse charging, and belongs to the technical field of electronics. The floating charger comprises a process indication unit, a parallel discharging unit, a parallel charging unit, an interface unit, a pulse unit, a dual-selection ending unit, a load unit and a trickle resistor. A charging circuit difficult to damage is achieved by a few activepieces, the parallel charging unit, the parallel discharging unit, the interface unit and the pulse unit are combined to form pulse charging of which charging and discharging are simultaneously performed and charging time is larger than discharging time, a triode in the parallel charging unit is connected in a constant-current mode and is also in 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 for a charged battery by the trickle resistor. After implementing the floating charger, the charging time and charging stopping time of the charged battery can be flexibly adjusted, different types of chargedbatteries 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...
