A testing system and a method for testing a battery cell are provided. The system includes a nest member that receives the battery cell, and a clamping device that secures a first battery tab between first and second connectors, and secures a second battery tab between third and fourth connectors. The system further includes a voltmeter that measures a voltage level between the first and third connectors when the first and second battery tabs are contacting the first and third connectors, respectively. The system further includes an ohmeter that measures a first resistance level between a first portion of the outer housing and the first connector when the first battery tab is contacting the first connector.

A method and apparatus for auditing condition of a storage battery (12) performs a battery test on the storage battery (12) to obtain a test result. Subjective information pertaining to the battery (12) is obtained. An audit code is generated based on the battery test result and the subjective information.
摘要:
A battery charging system with a power source for charging of one or more batteries by a control module having a microprocessor for readable instruction code, controlling flow of current and voltage to the output electrical components or circuits with sensors attached to each circuit, wherein the sensors provide information at least indicative of resistance in the battery corresponding to that circuit to an analysis module for computing the rate of change of resistance and comparing the rate to a completion criterion for each battery.

An inspection method of a secondary battery includes a charging step, an aging step, a pre-inspection discharge step, a voltage adjustment step, a self-discharge inspection step, and a deficiency determination step. A discharge condition in the pre-inspection discharge step is determined so that a voltage difference accumulation value Vs satisfies a predetermined range. The voltage difference accumulation value Vs is calculated by accumulating a value obtained by subtracting an output voltage from a predetermined voltage over a duration from start of the pre-inspection discharge step to end thereof.
