Patent ID: 7944662

Claim:
A multi-battery system for high-voltage applications with proportional power sharing comprising a circuit having a circuit positive terminal and a circuit negative terminal, said circuit comprising: a. at least two batteries, wherein each of said at least two batteries has a battery positive terminal and a battery negative terminal, and wherein the at least two batteries combine to provide a desired output voltage and a desired level of redundancy for the circuit; b. protection means for said circuit protection, said protection means connected across said battery positive terminal and said battery negative terminal of each of said at least two batteries, wherein the protection means has a protection means positive output terminal and a protection means negative output terminal; c. energy storage means connected to said protection means positive output terminal for temporary storage of energy within the circuit; d. logic circuit means for generating an output comprising a digital control signal for controlling energy discharge from said energy storage means; and, e. a voltage sensing element connected across said circuit positive terminal and said circuit negative terminal for sensing said circuit output voltage and for generating a digital enabling signal for input into said logic circuit means.
