Integrated oscillatory type floating charging equipment

Abstract

The invention discloses integrated oscillatory type floating charging equipment, and belongs to the field of electronic technique. The integrated oscillatory type floating charging equipment consistsof a trickle resistor, an integrated oscillating unit, a charging unit, a process indicating unit, a sampling ending unit, an interface unit and a load unit; after energization, high and low conversion of the interface unit is generated due to output of the integrated oscillating unit, two audions inside the charging unit are controlled, and thus a pulse charging and stopping charging manner is formed. When a battery is fully charged, the sampling ending unit is used for instant sampling, so that the charging unit is turned off during oscillation stop of the integrated oscillating unit, afterthe charging unit is turned off, the trickle resistor is used for providing required sustaining trickle current for the charged battery, and in the measure, the two audions inside the charging unit are used for charging the charged battery in a special parallel connection manner. Only the charging operating audion operates at ordinary times, the backup audion is dormant, and after the charging operating dormant is damaged, the backup audion is used for instantly substituting the operating audion to charge the charged battery. After implementation, the units are connected scientifically and arecomprehensively utilized, so that the circuit is simple and high in reliability.

Description

Technical field [0001] It belongs to the field of electronic technology. Background technique [0002] This company has applied for a security product series some time ago, and the product must have a backup battery, otherwise the security function will become a dummy when there is no city power, and when there is no city power, it may be the peak of a security incident. time. So backup battery is necessary. And the performance of the backup battery is directly related to the overall performance. [0003] But the backup battery must be charged and maintained. 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 by improper charging. The battery in the security equipment is a special battery, which has special requirements for volume and capacity, and the equipment is more demanding than general products. [0004] The reason why the most scientific c...

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
