High capacity batteries with on-demand fast charge capability

A battery pack, comprising:

• a high charge rate cell component;
• a processor;
• and
• a memory device accessible to the processor and storing code executable by the processor to:
• apply a normal rate of charge to a cell component of the battery pack;
• accept user input to switch the normal rate of charge to a second rate of charge which is higher than the normal rate of charge;
• and
• apply the second rate of charge to the high charge rate cell component based on the user input.

A method, comprising:

• displaying, on a display device of an apparatus, a graphical user interface, the graphical user interface having a switch interface therein for switching between a normal rate of charge and a higher rate of charge for charging a battery pack of the apparatus;
• receiving, at the apparatus, user input to the graphical user interface selecting a switching option of the switch interface;
• switching the charging of the battery pack from the normal rate of charge to the higher rate of charge, the battery pack including at least one high charge rate cell component;
• and
• applying the higher rate of charge to the at least one high charge rate cell component of the battery pack based on the user input.
