<p>Provided are a device for estimating battery life and a system for estimating battery life capable of accurate estimations by focusing on estimating the battery life on the basis of battery characteristics. A device for estimating battery life comprises a thermal flux detecting means (thermal flow sensor (2)) that detects temperature, of a secondary battery, fuel cell, or solar cell (1), in at least two locations by way of a temperature detecting means (first thermal element (22), second thermal element (23)), and measures the variation in thermal flux caused by deterioration of the battery (1) from the temperature difference of these two locations. The thermal flux detecting means (thermal flow sensor (2)) comprises a substrate (21), and a face of the substrate (21) is disposed substantially parallel to the mounting face of the battery (1).</p> |
