Combination battery device
专利汇可以提供Combination battery device专利检索，专利查询，专利分析的服务。并且PURPOSE:To enable both whether a combination battery has any remaining life or not and the length of the remaining life of the battery to be predicted by measuring the voltages of plural unit cells, and providing both a converter which converts the measured voltages into an index which indicates variation and a displayer which displays thus converted value. CONSTITUTION:In a converter 4, the voltage of each unit cell 1 is measured, and the average of the voltage of unit cells 1 is calculated. At the same time, the absolute value of the difference between the above average value and the voltage of each unit cell 1 is squared, thus obtained values of the unit cells 1 are totaled before divided by the number of the unit cells 1 so as to obtain the dispersion, and thus obtained value is displayed on a displayer 5. As a result, on the displayer 5, both a line 6 indicating this value, and a line 7 indicating the threshold of variations, that is a line indicating the life of a combination battery are displayed. Although the displayer 5 performs analog display in this example, a displayer which performs digital display can also be used.，下面是Combination battery device专利的具体信息内容。
