Simple P-type charger

Abstract

A simple P-type charger belongs to the technical field of electronics. The simple P-type charger is composed of a trickle resistor, a constant-current charging unit, a ring oscillation unit, a voltagestabilizing unit of an integrated circuit, a counter, a starting differential unit, a counting oscillation unit, an ending unit, a charging display unit, an ending sound unit and a load unit. The constant-current charging unit is controlled by the ring oscillation unit, and charges a charged battery at a constant current in a pulsed way. When powered on, the starting differential unit resets thecounter to ensure the accuracy of timing. The counting oscillation unit and the counter carry out timing. When timing ends, the ending sound unit makes sound, the ending unit is started to make the counting oscillation unit stop oscillating, the constant-current charging unit stops charging, the charging display unit is closed, and the trickle resistor provides a maintaining trickle current for the charged battery. After the measure is implemented, the units are connected scientifically, comprehensive utilization is achieved, the lines are simple, and the charger is easy to produce and debug,low in cost and easy to popularize.

[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
