Charger with primary battery for two-way I/O

A charger adapted with a primary battery to execute two-way input and output of the present invention including and external source, control circuit, one or a plurality of first rechargeable unit, one or a plurality of second rechargeable unit, casing, and optional indicator;

• the external source 101 being related to an AC source to be transformed and rectified into DC power before or after the input into the charger, other electricity installation to output its existing AC or DC source, or electric energy supplied from a generation unit that converts wind velocity, optical, thermal, or other kinetics into electric energy is essentially comprised of:
• an external source linking interface device 100:
• related to one that is adapted to the battery holder or a socket or plug set of the casing of the charger, or one that is adapted to a battery holder or a plug or socket set linked to a conductor 106 externally extending from the casing of the charger as intended to introduce the external source 101;
• to this purpose, one or a plurality type and one or a plurality of those linking interface devices described above may be provided as applicable;
• a control circuit 102:
• comprised of dynamo-electric or solid state electronic device for inputting external DC power, or external AC power to be transformed and rectified into DC power;
• the control circuit 102 may be disposed at one or a plurality of location as elected including (1) the charging device, (2) a first linking interface device 103, (3) a first rechargeable unit 203, (4) a second linking interface device 104, and/or (5) a second rechargeable unit 204;
• this control circuit 102 may be provided as applicable;
• for example, the control circuit 102 may not be needed if the external source 101 is given charging control function or if excellent charging match exists between the external source 101 and the voltage of the first rechargeable unit 203 or the second rechargeable unit 204;
• and when adapted, the control circuit 102 provides the following functions (1), (2), (3), and (4) as well as optional functions of (5), (6), and (7):
• (1) to control the external source 101 in charging the first rechargeable unit;
• (2) to control the external source 101 in charging the second rechargeable unit;
• (3) to control the first rechargeable unit 203 in outputting power to charge the second rechargeable unit 204 or to supply power to a load;
• (4) to control the external source 101 to charge both of the first rechargeable unit 203 and the second rechargeable unit 204;
• (5) to control the external source 101 to supply power to a load;
• (6) to control the first rechargeable unit 203 to supply power to a load;
• and
• (7) to control any two functions of any items of (1) through (6), or functions of any two items of (1) through (6) at the same time;
• the first linking interface device 103:
• related to one or a plurality of battery holder, plug or socket set that is disposed to the casing of the charger;
• or one or a plurality of battery holder, or plug or socket set linked to a conductor 106 externally extended from the casing of the charger to link the first rechargeable unit 203 and the control circuit 102;
• the second linking interface device 104:
• related to one or a plurality of battery holder, plug or socket set that is disposed to the casing of the charger;
• or one or a plurality of battery holder, or plug or socket set linked to a conductor 206 externally extended through the casing of the charger to link the second rechargeable unit 204 and the control circuit 102;
• wherein, one or a plurality of one type or multiple types of the battery holder or the plug or the socket set functioning as the first linking interface device 103 or the second linking interface device 104 described above may be provided as applicable;
• the first rechargeable unit 203:
• is comprised of one or a plurality of rechargeable battery, capacitor or super capacitor directly linked to the control circuit 102, or linked to the control circuit through the first linking interface device 103 comprised of the battery holder of the casing of the charger, or the plug or socket set, or linked to the control circuit 102 through the battery holder or the plug or socket set linked to the conductor 106 externally extended from the casing of the charger;
• and
• the second rechargeable unit 204:
• is comprised of one or a plurality of rechargeable battery, capacitor or super capacitor in the form of an individually provided rechargeable unit, or a rechargeable unit adapted to any type of load linked to the control circuit 102 by means of the second linking interface device 104 to input the power supplied from the external source 101 or the power supplied from the first rechargeable unit 203.
