N-type concise floating charger

Abstract

An N-type concise floating charger belongs to the electronic technical field, and comprises a purling resistor, a constant current unit, a charging unit, a gate circuit pulse unit, a voltage stabilization unit of an integrated circuit, a counting unit, a finishing unit, a charging display unit, a finishing sound unit, and a load unit; the constant current unit provides a constant current for the charging unit, the charging unit is controlled by the gate circuit pulse unit, thus forming a constant current charging process in a pulse mode; when the counting unit finishes timing, the finishing sound unit sends a prompt sound, the finishing unit starts, the clamping charging unit stops charging, the charging display unit stops displaying, the oscillations in the counting unit stop, and the purling resistor provides a maintenance purling for a charged battery; an excitation parallel gate, a gate 1 circuit, a gate 2 circuit, a gate 3 circuit, and a gate 4 circuit employ an inverter in an integrated circuit CD4069, so the line is concise, and integral utilization is realized; the N-type concise floating charger is easy to make, easy to debug, and very suitable for minisize enterprise production.

Description

Technical field [0001] It belongs to the field of electronic technology. Background technique [0002] With the enrichment of modern life, more and more types of electrical appliances using batteries, such as security equipment, digital machines, mobile phones, etc., have also appeared in many types of chargers, but these types lack a low-carbon Various types of environmentally friendly charging circuits. One of the meanings is that in the current product, the main charger is the circuit triode that stops charging, which is easily damaged. Once damaged, the charger becomes garbage. It is understood that this failure has become the main point of failure, and it becomes rubbish because of this point of damage. It is a great waste. (If it is repaired, it involves the cost of repair and the cost of the user to contact the repair department. So People often throw away). The second meaning is that in the charging process, there is no scientific charging of the battery when charging,...

AI Technical Summary

Problems solved by technology

[0002] With the enrichment of modern life, there are more and more types of electrical appliances using batteries, such as security equipment, digital machines, mobile phones, etc. For this reason, there are also many types of chargers, but there is a lack of a low-carbon battery in these types. Various types of environmentally friendly charging circuits

The first significance is that the charging supervisor in the current product is the circuit transistor that stops charging and is easily damaged. Once damaged, the charger becomes garbage.

It is understood that this failure has become the main failure point, and it is a great waste to turn it into garbage just because of this damage. People are often lost)

The second significance is that during the charging process, the battery is not charged scientifically, so it affects the capacity and life of the battery. It is also easy to turn the battery into garbage prematurely, which forms waste and pollutes the environment

(Waste batteries pollute the environment)

The reason for not achieving the most scientific charging is that the current products either only use DC to charge the battery, but do not use a better method, such as constant current charging; or even though they can be charged with a constant current source , but there are still some conveniences in use, or it is not scientific enough on the line, etc., so it should be enriched and developed
