Abstract:
A charging system for use in combination with an electrical system of the type having an alternator which provides an output voltage, a first battery, and a second battery, said charging system comprising:a voltage regulator which is operatively coupled to said alternator and which is effective to selectively cause said output voltage to equal a first voltage value and a second voltage value;a switch which is operatively coupled to said first battery, said second battery and said alternator, said switch being movable from a first position in which said first battery is connected to said alternator and said second battery is disconnected from said alternator to a second position in which said second battery is connected to said alternator and said first battery is disconnected from said alternator; anda controller which is communicatively coupled to said voltage regulator and to said switch, said controller being effective to cause said switch to move from said first position to said second position, said controller further being effective to cause said voltage regulator to cause said output voltage to equal said first voltage value when said switch is in said first position and to equal said second voltage value when said switch is in said second position, thereby selectively and alternately charging said first and said second battery.
