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 chargi

Abstract

The invention discloses a simplified double selection pulse float charger, and belongs to the technical field of electronics. The simplified double selection pulse float charger is composed of a process indicting unit, a voice prompt unit, an N-type charging unit, an N-type discharging unit, an interface unit, a pulse unit, a double-selection termination unit, a load unit, and a trickle resistor.The N-type charging unit and the interface unit, and the pulse unit cooperate so as to form a pulse-type scientific charging method. A constant current triode of the N-type charging unit is connectedin the form of constant current, therefore forming constant current charging. The double selection termination unit has termination after the full charging of the battery and termination after the endof the timing countdown which can easily switch. After the end of charging or discharging, the trickle resistor provides required trickle current to a to-be-charged battery. In the line, the constantcurrent triode serves to control the on and off in charging and provides double functions of a constant current source, thus simplifying the line. The constant current charging apparatus can performcharging in a more scientific manner and provide maximum charging, so that the constant current charging apparatus can increase the service life and capacity of a charger and the to-be-charged batteryat the maximum and protect environment.

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...
