Abstract
A battery pack is provided for use when charging of a dedicated secondary battery in a portable terminal device is difficult. The battery pack is mounted in a battery mounting section in a portable cellular phone. In the battery pack, alkaline accumulators are connected in series. Alkaline accumulators generate electromotive forces having a voltage (3V) being lower than that of the dedicated secondary battery. A power source circuit has a boosting--type DC/DC converter which boosts a voltage of the alkaline accumulators being connected in series at a level same as that of the dedicated secondary battery (for example, 4.5V), and outputs the boosted voltage. An electrical double layer capacitor has a capacity to feed stable power to an internal circuit in which power consumption increases or decreases in a burst manner and is charged by application of an output of the power source circuit and stores the power.
Claims (5)
1. A battery pack being placed in a portable terminal device in a manner so as to be replaceable with a dedicated secondary battery for being used as a power source of said portable cellular device comprising:
a primary battery to generate electromotive force having a voltage being almost same as that of said dedicated secondary battery;
a power storing unit to be charged by application of a voltage output from said primary battery and to store fed power and to feed the stored power to said portable terminal device;
a current interrupting unit to interrupt, when a current output from said battery pack exceeds a predetermined value, said output; and a diode to prevent backflow of a current to said primary battery.
a primary battery to generate electromotive force having a voltage being almost same as that of said dedicated secondary battery;
a power storing unit to be charged by application of a voltage output from said primary battery and to store fed power and to feed the stored power to said portable terminal device;
a current interrupting unit to interrupt, when a current output from said battery pack exceeds a predetermined value, said output; and a diode to prevent backflow of a current to said primary battery.
2. A battery pack being placed in a portable terminal device in a manner so as to be replaceable with a dedicated secondary battery for being used as a power source of said portable cellular device comprising:
