PROBLEM TO BE SOLVED: To realize improvement of battery capacity and reduction in size and light weight by controlling, depending on the voltage and current required by a plurality of power feeding terminals, a switch which can connect a plurality of batteries and power feeding terminals through combination of desired serial connection or parallel connection. SOLUTION: A control signal C1 from a control means 5 operates for SW (1 to 4) of a switch means 4 and when respective SW is closed, the required 3E[V] (E is an electromotive force of each battery) is supplied across the ground terminal 3 and power feeding terminal 2. In the same manner, the voltage 3E[V] is always supplied across between the ground terminal 3 and power feeding terminal 2, by controlling the switch means 4 through selection of one of the control signals C1 to C4 outputted from the control means 5. As a result, a flexible power supply apparatus which have realized battery capacity and reduction in size by reinforcing the battery capacity with a desired number of batteries, in addition to the number of batteries as many as the number of serial connections required for the voltage which is required for the power feeding terminal 2. |
