POWER SUPPLY METHOD WITH PARALLEL-CONNECTED BATTERIES
First Claim
1. A power supply method with parallel-connected batteries;
- characterized in that at least two power supply branches being connected parallelly;
each power supply branch including batteries, a step-up circuit, and a step-down circuit, and each power supply branch further being installed with an individual control unit;
said batteries providing a low voltage that would be transformed into a high voltage via said step-up circuit, thereby permitting said high voltage to be transformed to a desired power-supply voltage via said step-down circuit;
an output of said power supply branch being serially connected with a diode for preventing another power supply branch from a reverse current;
a cathode of said out put being serially connected with a current limiting resistance for balancing currents generated from each of said power supply branches.

Abstract
A power supply method with parallel-connected batteries employs at least two parallel-connected power supply branches, each of which includes a battery, a step-up circuit, and a step-down circuit, and each of which is installed with an individual control unit. The battery offers a low voltage transformed into a high voltage via the stepping-up. The high voltage thence acquires a needed power-supply voltage through the transformation executed by the step-down circuit. An anode of an output of the power supply branch serially connected with a diode prevents the other power supply branch from a reverse current. A cathode of the output serially connected with a current limiting resistance balances the currents on each power supply branch. Accordingly, the present invention diminishes the workload of the device maintenance, lessens users'"'"' investment pressure, and provides electricity systems of the power plant and the substation with a consistent direct current power source.
