Comparative Abuse Testing of 36 V and 12 V Battery Designs

Comparative abuse tests were performed on commercially available 12 V and 36 V battery designs. Four methods were chosen from SAE J2464 standard, Electrical Vehicle Battery Abuse Testing, March 1999, and modified to apply them to typical-sized automotive batteries. The four tests included a Penetration Test, Crush Test, Radiant Heat Test, and Short Circuit Test. Both the 12 V and 36 V batteries showed minimal reactions to the tests, and there was no significant difference between results of the two designs with respect to the abuse tests performed. It should be stressed however, that this project was limited in scope and was not intended to be a thorough investigation in the batteries safety hazards.
