Battery charger capable of ending dual selections

Abstract

A battery charger capable of ending dual selections belongs to the technical field of electronics and comprises a constant-current source, a process display unit, a charging control unit, a charging unit, a discharging control unit, a discharging unit, an annular oscillation unit, a selection dual-ending unit, a load unit and a trickle resistor, wherein the annular oscillation unit is used for controlling the charging control unit and the discharging control unit, the charging control unit and the discharging control unit are used for controlling the charging unit and the discharging unit to be switched on and switched off to form a pulse charging mode that the discharging unit is switched off when the charging unit is switched on and the discharging unit is switched off and the charging unit is switched on, a current is provided for the charging unit by the constant-current source, constant-current charging is also performed, two ending modes in the selection dual-ending unit are selected and are flexible and convenient, the charging unit and the discharging unit are simultaneously switched off when the selection dual-ending unit is started, a trickle current is provided for a charged battery by the trickle resistor, all units are scientifically connected after implementation, integral utilization is achieved, and the battery charger is easy to produce and debug and is suitable for production of a miniature enterprise.

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 ...

AI Technical Summary

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 batteries) and the end of timing (this method is suitable for charging non-activated batteries and a large class of batteries such as acid)

The third is that there is no way to use active components for conversion to solve the problem that the charging tube is fragile

If the switch tube is in a pulsed state, it is more likely to become damaged and increase the overall scrapping of the charger
