Safety Evaluation of an Electronic Totalizer Containing a Li/(CF)x Cell.

摘要

A safety review and test program has been conducted on the Electronic Totalizer Model 799806-212 manufactured by Veeder-Root containing the Panasonic Lithium Polycarbonmonofluoride battery (one cell) BR-2/3A. The cell is used for the LCD display of the totalizer. Tests were conducted on the cell both inside the totalizer and alone. Tests included short circuit, forced discharge into voltage reversal, charging, heat tape, and gas sample collection of combustion products. The tests were run on both fresh cells and partially discharged cells. The forced discharge and charging tests were conducted at both the 250mA and 1 amp level. No fire or flame was noted during the tests with the exception of the heat tape runs. During heat tape tests fire was noted at 450 C.
