<p>PROBLEM TO BE SOLVED: To provide a method for compressing/expanding battery data which can increase the compression rate of data even when compressing and saving a current value and a voltage value of a battery at each time as paired data.SOLUTION: The method for compressing/expanding battery data, which saves a current value and a voltage value of a battery at each time as paired data, for data compression, calculates a present current variation prediction value by the use of a variation between preceding and present voltage values, calculates a difference between the present current variation prediction value and an actual variation of a present current value, and saves the difference as data. For data expansion, a present current variation prediction value is calculated by the use of a variation between preceding and present voltage values, and a difference between the present current variation prediction value and an actual present current value is added to the present current variation prediction value to calculate a variation of the present current value.</p> |
