Use of adjustable battery system within a vehicle with an HV battery or fuel cell system

A battery control system, comprising:

• first and second batteries each comprising:
• first and second terminals configured to output a first voltage;
• third and fourth terminals configured to output a second voltage different from the first voltage;
• a plurality of individually housed batteries;
• and
• a plurality of switches configured to connect any one of the individually housed batteries to and from any one of the first, second, third, and fourth terminals;
• a plurality of switching devices arranged between (i) the first, second, third, and fourth terminals and (ii) a first set of loads and a second set of loads;
• and
• a control module configured to control the plurality of switches and the plurality of switching devices to (i) selectively provide the first voltage from the connected ones of the individually housed batteries of either one of the first battery and the second battery to the first set of loads and (ii) selectively provide the second voltage from the connected ones of the individually housed batteries of either one of the first battery and the second battery to the second set of loads,
• wherein the plurality of switching devices includes a first switching device configured to receive and selectively output the first voltage from the first battery and a second switching device configured to receive and selectively output the first voltage from the second battery,
• wherein the plurality of switching devices includes a third switching device configured to receive and selectively output the second voltage from the first battery and a fourth switching device configured to receive and selectively output the second voltage from the second battery, and
• wherein the plurality of switching devices includes a fifth switching device configured to (i) receive the first voltage from either one of the first switching device and the second switching device and (ii) supply the first voltage to the first set of loads.
