Smart charging system for hybrid battery pack

A method for providing power to a mobile computing system, said method comprising:

• supplying demanded current by said mobile computing system from a primary battery while said demanded current is determined to be continuous;
• supplying demanded current to said mobile computing system from a secondary battery while said demanded current is determined to be transient;
• charging said secondary battery by drawing current from said primary battery in a predetermined rate while said secondary battery supplying demanded current to said mobile computing system;
• and
• charging said primary and said secondary battery responsive to detecting presence of an external charging device, said external charging device operable to charge said primary battery and said secondary battery, and operable to supply demanded current to said mobile computing system;
• and wherein said primary battery has higher energy density than said secondary energy density, and wherein further said secondary battery is operable to withstand transient current reliably.

A mobile computing system comprising:

• a power source comprising
• a primary power component operable to supply continuous current;
• a secondary power component coupled in parallel to said primary power component and operable to supply transient current;
• a system load coupled to said power source that demands current from said power source, said system load comprising:
• a display;
• a bus;
• a main processor;
• and a memory;
• and
• control logic coupled to said power source and operable to:
• determine whether current demanded by said system load is continuous or transient;
• disconnect said primary source component from said system load upon determining said current demanded to be transient;
• and
• enable said primary power component upon determining said current demanded to be continuous.
