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

[0117] figure 1 , 2 , 3, 4, and 5 show a specific implementation example of a pulse timing low-carbon environmental protection charging device, image 3 Figure 4 Figure 5 Example of detection map in implementation.

[0118] 1. Selection of components: the gate in the pulse generating unit and the base control gate of the interface triode, and the gate in the end control unit are welded together with 6 gates inside a CD4069, and the two triodes in the interface triode and the discharge unit use high-power NPN triode, the two triodes in the discharge unit use 2N5401, the diodes use surface-bonded diodes, the discharge resistors use high-power models, and there are no special requirements for other resistance-capacitance components.

[0119] 2. Plate making and welding: press figure 2 Make the circuit control board, connect figure 2 The schematic diagram for welding.

[0120] The charging display unit is composed of a charging indication protection resistor (2.1 in 2) a...

Abstract

The invention provides a pulse timing low-carbon and environment-friendly charging device, and belongs to the technology of electronics. The pulse timing low-carbon and environment-friendly charging device is composed of a charging display unit, an interface unit, a charging unit, a pulse generation unit, a discharging unit, a sampling adjustable unit, an end control unit and a load unit. After the power is on, all the units start to work, wherein the charging unit and the discharging unit perform the process on a charged battery in which charging is greater than discharging. When the charging unit is powered on for charging, the discharging unit is powered off; and when the charging unit is off, the discharging unit is powered on for discharging so as to form the mode of pulse charging until completion of charging. The cutting switch in the discharging unit can also be used for cut-off so as to increase the flexible selectivity. After the charged battery is fully charged, the charging unit and the discharging unit are powered off, and then the trickle resistor in the charging unit provides trickle current required for maintenance of the charged battery. After application of the device, all the units are scientifically connected, and comprehensive utilization can be realized, the line circuit is concise and the reliability is high so that the device is quite suitable for miniature enterprise production.

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...
