Electric Vehicle Battery Abuse Testing
|Publication Date:||1 March 1999|
1. Scope--This SAE Recommended Practice is intended as a guide toward standard practice and is subject to change to keep pace with experience and technical advances. It describes a body of tests which may be used as needed for abuse testing of electric or hybrid electric vehicle batteries to determine the response of such batteries to conditions or events which are beyond their normal operating range. This document is derived from a similar document originally developed by the U.S. Advanced Battery Consortium. (See 2.2.1.)
1.1 Purpose--These tests are intended to simulate abuse conditions and potential internally initiated failures that may be experienced in electrochemical storage systems. These tests were derived from Failure Mode and Effect Analysis, user input and historical abuse testing. The outcome of testing shall be documented for use by potential users of the tested properties. It is not the intent of this procedure to apply acceptance criteria; each application has its own unique requirements and ancillary support systems. Users of these technologies shall make their own determination as to what measures to take to ensure a sound application of said technology.
The tests are designed to provide a common framework for various Electrochemical Storage Systems (ECSS) technologies. The primary purpose of the tests is to gather response information to external/internal inputs. Some tests and/or measurements may not be required for some ECSS technologies and designs if it can be demonstrated that the test is not applicable and the measurement will yield no useful information.
Note that the device to be tested using any of the procedures in this document is referred to as an Electrochemical Storage System (ECSS); this terminology may refer to an electrochemical cell, module or complete battery system, depending on the particular test.
