Abstract

The invention provides a constant current type hybrid environmental protection charging device, which belongs to the electronic technology field and comprises a charging unit, a process and end indicating unit, an end executing unit, an end switching switch, a timing ending unit, a trickle resistor and a load unit. As the two transistors of the charging unit are connected in a constant current manner and are connected in parallel through a special way to form or-gate output, the charging process is one charged by constant current. Further, only one transistor works while the other transistor stands by. When the working transistor is damaged, the other one replaces. According to the invention, there are two ending manners available with one being that when the end voltage of a charger cell rises, the end executing is initiated after sampling to form the closing of the charging unit and the other being that when the counting of the end counting unit is completed, the end executing unit is initiated to form the closing of the charging unit. The end switching switch forms the selection. When the charging unit is closed, the trickle resistor provides trickle current to the charged cell for its maintenance.

Description

technical field [0001] It belongs to the field of electronic technology. Background technique [0002] With the enrichment of modern life, many electrical appliances use batteries. Its advantage is that as long as it is fully charged, it can be used anytime and anywhere, and is not affected by AC mains power. Therefore, the types of electrical appliances using batteries are more and more There are more and more types of chargers, such as digital machines, mobile phones, etc. For this reason, there are many types of chargers, but there are still insufficient types of low-carbon and environmentally friendly charging circuits in these types, and the significance of low-carbon and environmentally friendly charging circuits is now The charging director in the product, which is the circuit transistor for connecting and shutting off the charging, is easy to be damaged, and once damaged, the charger becomes garbage. According to statistics, this failure has become the main failure ...
