In recent years, the semiconductor integrated circuit technology developed, it changes in consumer electronics products updates and use short, gradually towards the purpose of facilitating the development，and gradually got used to save the battery can be used as component, but also makes batteries used in certain conditions to
develope a variety of uses and specifications, and a wide range of applications in
electronics, UPS systems, laptops and electric vehicles.
In order to achieve low-cost sections of the CC-CV Battery Charger, this paper uses the general electronics store selling the fixed-voltage AC to DC switching power
supply as the main charge structure, to achieve a control circuit for the use of electrical devices connection between the battery voltage feedback signal, so that it
has changed the battery charging mode and adjustable voltage and current capabilities, thus achieving the effect of a low-cost and self-adjustment of intelligent charger.
