Double N-type pulse environmentally-friendly charging device

Abstract

The invention relates to a double N-type pulse environmentally-friendly charging device and belongs to the electronic technical field. The double N-type pulse environmentally-friendly charging device is composed of a charging part, a pulse generating unit, a termination and starting adjustable unit, a charging display circuit, an termination and starting control unit, a discharging part and a load unit; an oscillation circuit in the pulse generating unit can be a control circuit for forming charging pulses of the charging part and the discharging part. When the charging part is turned on and performs charging, and the discharging part is turned off; when the charging part is turned off, and the discharging part is turned on; and therefore, a scientific pulse charging mode according to which charging time is longer than discharging time can be realized. After a battery is fully charged, the charging part and the discharging part are turned off, and a tiny resistor in the charging part provides maintaining current for a power source. With the double N-type pulse environmentally-friendly charging device of the invention adopted, both of the charging part and the discharging part have a back-up automatic switching function, and therefore, the reliability of a circuit can be ensured, charging-while-discharging pulse charging is realized. The pulse generating unit can flexibly adjust frequency and the time of duty ratio, and therefore, the double N-type pulse environmentally-friendly charging device is convenient and reliable, and can adapt to rechargeable batteries of different capacities.

Description

technical field [0001] It belongs to the technical 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. Therefore, how to ens...

[0007] However, according to the above-mentioned charging method, the conventional circuit also has technical difficulties, because the conventional circuit is not a circuit that charges and discharges, and its switch control tube is the focus of the fault. If the switch tube is in a pulsed state, it will be easier. The probability of becoming damaged is one, and the second is because the circuit has the control of charging and the control of discharging part (or stop charging), so the damaged part has doubled, so if the traditional design is used, it must be The circuit is complicated, and new fault points have been added. How to solve these contradictions has become a new difficulty
