摘要： A method and apparatus for testing a storage battery is provided that generates a temperature at which the battery will fail to meet performance criteria. The use of a temperature-based system to rate battery performance provides a clearer understanding to those not skilled in the art of battery testing. The critical failure temperature (112) is obtained using the battery parameters of open circuit voltage (110), temperature (106) and a dynamic parameter (104) such as conductance or resistance.

摘要： An apparatus (10) for electronically testing or monitoring the condition of a storage battery (12) is provided. The apparatus (10) includes an inductance cancellation circuit (20) for use with a Kelvin probe (16A, B, 18A, B) of the electronic battery tester (10). The induction cancellation circuit (20) reduces inductive coupling between lead of the Kelvin probe (16A, B, 18A, B). The apparatus (10) also includes a DC coupled AC amplifier (24) for amplifying an AC response signal of the electronic battery tester (10). Other aspects include a critically damped band-pass filter (28), a DC to DC convertor isolation circuit (48), operator editable test criteria, a battery temperature sensing element (25), an automatically adjustable gain stage (32) and the use of an internal reference standard (21) for a self calibration.
