Problems solved by technology

[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

Abstract

The invention, which belongs to the field of the electronic technology, provides a PNP type pulse charger comprising a charging display unit, a P type charging unit, an interface unit, an integrated pulse generation unit, a timing control unit, an ending unit, an N type discharging unit, and a load unit. After connection of a power supply, the P type charging unit and the N type discharging unit charge a charged battery in a pulse current manner under control of the integrated pulse generation unit and the interface unit; during the charging process, charging and discharging are carried out simultaneously until the charging ends, wherein the charging process is longer than the discharging process; and a cutting switch in the discharging unit can be used for cutting, so that selection flexibility can be enhanced. After charging time of the charged battery reaches specified time, the charging unit and the discharging unit are turned off and a trickle resistor in the charging unit provides a needed holding trickle current for the charged battery. After implementation of the PNP type pulse charger, all the units are connected scientifically; integrated utilization is realized; the circuit is simplified; and reliability is high.

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...
