Double-N oscillation constant-current charger

Abstract

A double-N oscillation constant-current charger belongs to the technical field of electronics. The double-N oscillation constant-current charger is composed of a constant-current charging unit, a double-N tube oscillation unit, an end common-mode amplification unit, a charging end warning unit, a trickle resistor and a load unit. After the charger is powered on, the constant-current charging unitcharges a charged battery in the load unit. The double-N tube oscillation unit controls the on-off of the constant-current charging unit. Therefore, the whole charging process is a pulse charging process. After the battery is fully charged, the end common-mode amplification unit is started to make the double-N tube oscillation unit stop oscillating, the constant-current charging unit is closed tostop charging, the charging end warning unit sends out an acousto-optic prompt, and the trickle resistor provides a maintaining trickle current for the battery. The charging working tube in the constant-current charging unit not only controls the on-off of charging, but also forms a constant current source, thus playing a dual role. Scientific utilization is achieved. The double-N oscillation constant-current charger costs low, and is thus 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
