Vibration Testing of Electric Vehicle Batteries
RATIONALE
SAE J2380 provides a test procedure for characterizing the effect of long-term, road-induced vibration and shock on the performance and rvice life of electric vehicle batteries. For mature, production-ready batteries, the intent of the procedure is to qualify the vibration durability of the battery. The vibration spectrum has been synthesized from rough-road measurements is the late 1990s.
Vibration and shock tests are relevant to the new fleet of electric or hybrid electric vehicles that are being developed with advanced battery technology.自动拖把
FOREWORD
This document provides a test procedure for characterizing the effect of long-term, road-induced vibration and shock on the performance and rvice life of electric vehicle batteries. For mature, production-ready batteries, the intent of the procedure is to qualify the vibration durability of the battery. Either swept sine wave vibration or random vibration is typically ud for the performance of such testing. However, swept sine wave testing is considered somewhat more reprentative and is addresd in this document, which is generally bad on a corresponding test for electric vehicle batteries developed by the U.S. Advanced Battery Consortium.
The vibration tests defined in this procedure are bad on rough-road measurements at locations likely to be appropriate for mounting of traction batteries in EVs. The data were analyzed to determine an appropriate cumulative number of occurrences of shock puls at various given G-levels over the life of the vehicle. The vibration envelopes shown in Figure 1 of this procedure correspond to approximately 100 000 miles of usage at the 90th percentile. The vibration spectra co
ntained in this procedure have been designed to approximate this cumulative exposure envelope. For testing efficiency, a time-compresd vibration regime is specified to allow completion of the test procedure in a minimum of 13.6 h and a maximum of 92.6 h of testing, depending on the type of shaker table available and the choice of acceleration levels.

1. SCOPE
This SAE Recommended Practice describes the vibration durability testing of a single battery (test unit) consisting of either an electric vehicle battery module or an electric vehicle battery pack. For statistical purpos, multiple samples would normally be subjected to such testing. Additionally, some test units may be subjected to life cycle testing (either after or during vibration testing) to determine the effects of vibration on battery life. Such life testing is not described in this procedure; SAE J2288 may be ud for this purpo as applicable.

Except as specifically noted in this ction, the definitions of SAE J1715 shall apply to this document.
4. TECHNICAL REQUIREMENTS
4.1 Prerequisites
A battery test plan or other test requirements document is normally required for testing using this procedure. The test plan specifies the appropriate test conditions for the Reference Performance Tests (e 4.4.1) and certain vibration frequencies to be ud, along with testing precautions and any special handling/testing instructions specified for the battery by the manufacturer and/or the test sponsor. Note that SAE J2464 also describes shock tests (25 g acceleration, half sine wave form with duration of 15 mc).
Performance of certain Reference Performance Tests specified in SAE J1798 is normally required before and after the conduct of vibration testing. For completeness, the are itemized within the pr
ocedure steps in 4.4.
Unless otherwi specified in a test plan document, the test unit shall be tested early in its life (i.e., prior to the performance of any life cycle testing.)
4.2 Test Equipment
4.2.1 Equipment
Performance of this procedure requires a one- to three-axis table capable of producing accelerations up to 1.9 G over the vibration spectra detailed in Figure 2, extending from 10 to approximately 200 Hz. If the unit to be tested can only be vibrated while in a particular physical orientation, a multi-axis table will be required. Additionally, the time required to perform the test can be significantly reduced if the longitudinal and lateral axis vibration (or all three axes) can be performed concurrently.
4.2.2 Fixtures
Test fixtures are required to properly cure the test unit to the shaker table. The exact nature of the fixtures depends on the type of table ud, the test unit itlf, and any restrictions on physical orientation of the test unit.
4.2.3 Instrumentation
Special instrumentation hookups capable of withstanding the vibration are required so that important battery conditions can be monitored during testing. (See 4.5.)
4.3 Determination of Test Conditions and Test Termination Criteria
4.3.1 Electrical Test Conditions
Are determined according to the procedures in SAE J1798 which are specified in 4.4.1.
4.3.2 Vibration

Frequencies
Vibration test conditions are as specified in the procedure steps in 4.4.
Termination
4.3.3 Test
清热润燥
Vibration testing shall be suspended or terminated if any obrved component degradation produces conditions which are abnormal or outside the operating ranges of the battery as specified by the manufacturer. Conditions to be monitored are defined in 4.5.
Procedure
4.4 Test
4.4.1 Perform a quence of Reference Performance Tests consisting of a C/3 Constant Current discharge, a Dynamic
Capacity Test discharge to 100% of rated capacity, and a Peak Power discharge, as defined in SAE J1798.
4.4.2 Charge the battery fully using the manufacturer's recommended charge method.
4.4.3 For each of the vertical, longitudinal, and lateral axes of the battery, lect either the normal or alternative
G-levels from Table 1 and program the shaker table appropriately. This choice will determine the vib
ration time required for each axis, also in accordance with Table 1. (The vibration spectra, shown in Figure 2, are expresd in G2/Hz, so they can be scaled for either t of G-levels.)
