Problems solved by technology

[0008] The reason for the lack of current products is that there is no constant current and pulse charging circuit, and this circuit has a relatively simple circuit, and can flexibly adjust the relationship between charging and stopping, and the second is that it does not have a limited voltage. A circuit that combines the end of charging (this method is suitable for activated batter

Abstract

The invention discloses oscillation-type environmental protection pulse floating charging equipment, and belongs to the technical field of electronics. The equipment consists of a constant current source, a ring oscillator unit, a charging unit, a discharging unit, a process display unit, an interface unit, a double-end unit, an end change-over switch, a load unit, and a trickle resistor. An integrated circuit employing a phase inverter forms the ring oscillator unit, and controls the discharging unit, controls the charging unit through an interface triode, and achieves the charging and discharging pulse-type charging. Because the current of the charging unit is provided by the constant current source, the charging mode is a constant-current charging mode. Two end modes in the double-end unit are switched through the end change-over switch, and trigger the interface unit, so as to turn off the charging unit, and enable the ring oscillator unit to stop oscillation. A low voltage is outputted, and the discharging unit is turned off. At this moment, the trickle resistor provides a trickle current for a battery, and the charging and discharging units have standby tubes which are substitutes when a working tube is damaged, thereby improving charging reliability.

Description

technical field [0001] It belongs to the field of electronic technology. Background technique [0002] With the enrichment of modern life, there are more and more types of electrical appliances using batteries, such as digital machines, mobile phones, etc., and many types of chargers have appeared for this reason, but there are still many types of low-carbon and environmentally friendly charging circuits in these types. exist. [0003] One of its meanings is that in current products, the charging director, which is the circuit transistor that connects and shuts off the charging, is easily damaged. Once damaged, the charger becomes garbage. According to statistics, this failure has become the main failure point of the charger. It is a great waste to turn it into garbage just because of this damage. cost, so people are often throwing away). [0004] The second meaning is that during the charging process, the battery is not charged scientifically, which affects the capacity ...
