<p><P>PROBLEM TO BE SOLVED: To solve the problem that a conventional system does not discharge energy efficiently, if it uses a detected voltage discharged from an accumulating device with an internal voltage and a recommended lower limit voltage as a terminal voltage and stops its discharge when this value comes to a recommended lower limit voltage. <P>SOLUTION: The voltage lower limit value to stop the discharge of the accumulating device is set to a value obtained by subtracting a drop voltage (the product of a discharge current and an internal resistance value) due to an internal resistance from the recommended lower limit voltage. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
