Supplemental capacitor based battery charging system

A portable charging device comprising:

• a) a case;
• b) a charging device power input receiving input power;
• c) a charging device power output;
• d) a battery located within the case, the battery having a battery charge status output;
• e) a supercapacitor located within the case, the supercapacitor having a supercapacitor charge status output;
• f) a processor operating according to instructions causing the processor to implement a charging device management system;
• and
• g) the charging device management system having an input logic that, upon determining that there is input power on the charging device power input:
• i) receives the battery charge status output and the supercapacitor charge status output,
• ii) upon determining that the supercapacitor is not full, using the input power to charge the supercapacitor, and
• iii) upon determining that the supercapacitor is full and that the battery is not full, using the majority of the input power to charge the battery while providing a trickle charge to the supercapacitor to maintain the supercapacitor at full charge.

A method for managing input and output power in a hybrid portable charging device containing a battery and a supercapacitor comprising:

• a) receiving a battery charge status output and a supercapacitor charge status output;
• b) determining whether the hybrid portable charging device is receiving input power;
• c) upon determining that the hybrid portable charging device is receiving input power:
• i) determining whether the input power is at a low, medium, or high level,
• ii) upon determining that the input power is at the high level, diverting all input power to the supercapacitor until the supercapacitor charge status output indicates that the supercapacitor is fully charged,
• iii) upon determining that the input power is at the low level, diverting all input power to the battery until the battery charge status output indicates that the battery is fully charged, and
• iv) upon determining that the input power is at the medium level, dividing the input power into a first portion that is diverted to the battery and a second portion that is diverted to the supercapacitor.
