Abstract

The conventional automatic cut-off and transient holding-type charging circuit has the disadvantages in having numerous components, complex structure, increased cost and low reliability. The automatic cut-off of operation control for temperature control switch and the transient holding-type charging circuit for wide voltage variation range are formed by using the operation conditions of transient holding-type charging circuit used for wide voltage range and the temperature control switch for detecting the chargeable battery temperature. When a battery is charged completely and the battery temperature is raised to a setting value, temperature control switch is activated so as to make circuit automatically switch to a small current mode and remain at a charging state. The first feature of the invention is that a RESET function is generated as the battery is unloaded, or power source is terminated when a temperature control switch automatically returns and remains at a charging state within the set variation rage of power source voltage. The further character of the circuit is that it can be further used to have the back-flow diode so as to form the emergent automatic power supply function.
