Improvement of failure detection of production line test results by implementing ΔV criteria

摘要

The relibility of automotive batteries is an important factor, especially for the OEM market. To ensure consistent reliability all automotive batteries are subjected to electrical load tests prior to shipment. These tests are performed in accordance with industry accepted standards. It is essential that the energy discharged from the battery during test be minikmized to avoid the cost and delay associated with recharge. When defining the ideal high rate discharge test process one must consider these basic requirements.
