Patent abstract
A cell evaluation device has a short circuit detection portion to detect an internal short circuit within a test cell that has been subjected to nail penetration or crushing using the pressure from a pressurization portion, a pressure control portion to halt the operation of the pressurization portion on detection of a short circuit, and a cell information detection portion to collect and record cell information such as the cell temperature. By using such a cell evaluation device, the location of an internal short circuit during an abuse test is specified, and variations in the cell temperature increase accompanying the internal short circuit is minimized.
