Environmental-friendly type cell float charger

Abstract

The invention relates to an environmental-friendly type cell float charger and belongs to the electronic technology field. The float charger comprises a float charging unit, a sound control unit, an interface unit, a pulse unit, a selection unit, a counting unit, a voltage limiting starting unit, a load unit, a process indicator unit and an ending unit, wherein the float charging unit, the pulse unit and the interface unit commonly form a charging / discharging pulse charging mode, the charging time is longer than the discharging time, a charging work tube and a charging standby tube in the float charging unit are in different work states, during common use, only the charging work tube works, the charging standby tube is in an open circuit state, after the charging work tube is damaged, thecharging standby tube automatically works for conduction. The float charger is advantaged in that an ending mode after fully charging of a cell and an ending mode after timed counting in place are employed and are two flexible conversion modes, after charging ends, the sound control unit starts to prompt a user, after enforcement, scientific and maximum charging of the charged cell is realized, service life and the capacity of the charger and the charged cell are improved to the maximum degree, and social environmental friendliness is realized.

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
