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

Embodiment Construction

[0097] figure 1 , figure 2 , image 3 , Figure 4 An example scheme for the manufacture and testing of a double N-type pulse environmental protection charging device is given.

[0098] 1. Select components: the charging working tube and charging backup tube are high-power triodes, the oscillating N tube is 8050, the oscillating P tube is 8550, the control thyristor is a one-way thyristor, and the discharge resistor is a high-power type resistor. The capacitor adopts a capacitor with a small leakage coefficient, and there is no special requirement for other resistance-capacitance components.

[0099] 2. Plate making and welding: press figure 2 Make the circuit control board as shown, and connect figure 2 The schematic diagram for circuit soldering.

[0100] 3. Power on, check and debug.

[0101] 1. The power-on inspection and debugging of the end-start adjustable unit and the end-start control unit. (see image 3 ).

[0102] A. Adjust and determine the end start groun...

Abstract

The invention provides a double-N type pulse environment-friendly charging device, and belongs to the technical field of electronics. The device is formed by a charging portion, a pulse generation portion, an end-start adjustable unit, a charging display circuit, an end-start control portion, a discharge portion, and a load unit, and oscillation of the pulse generation unit is a control circuit for forming pulse charging of the charging portion and the discharge portion; when the charging of the charging portion is switched on, the discharge portion is switched off; when the charging portion is switched off, the discharge portion is switched on so that a scientific pulse charging mode in which the charging time is longer than the discharge time is formed; and when a battery is fully charged, the charge portion and the discharge portion are switched off, and a trickle resistor in the charging portion provides maintenance current to a charged power supply. According to the device, the charging portion and the discharge portion both have the standby automatic switching function, the circuit reliability is guaranteed, pulse charging while charging and discharge is formed, the pulse generation unit can flexibly adjust the frequency and the time of duty ratio, convenience and reliability are achieved, and the device is applicable to the charged batteries with different capacities and is a convenient environment-friendly charging device.

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...
