摘要:
A status tester for an electrochemical cell (1), comprising an (1) elecrically resistive element (18), switchably contactible with the (18) terminals of the cell, and visual heat responsive means (24) thermally connected with the resistive means such that, on passage of electric current through the resistive element, heat generated thereby excites the heat responsive means, has at least two switches (65a, 65b) for one (65a, 65b) terminal, each switch being associated with an overall different electrical resistivity of the resistive element, thereby to allow testing for suitability for high and low drainage devices. Incorporation of a variable resistivity element, where resistance changes with ambient temperature, allows the tester to provide consistent results over a range of ambient temperatures.

The invention relates to a method for sorting batteries (10), with batteries being separated on the basis of a measured electrical property which is characteristic of their composition. The electric property of the battery is according to the invention determined by applying to the battery (10) a varying electrical voltage and measuring the resulting current through the battery. The varying electrical voltage advantageously consists of a first pulse and a second pulse which have opposite polarities, and which may both be generated by the discharge of a capacitor (2). In addition, a second property may be determined, e.g., the shape or colour of the battery. With such method, a very effective separation between, e.g., nickel-cadmium, alkaline, lithium, and other batteries may be obtained. The invention further relates to a device (1) for determining electrical properties of batteries.
摘要:
A device and method for sorting batteries of used batteries and accumulators on the basis of their chemical constitution. The measurement device is based on the analysis of the inductive effect produced by the substances which are contained in the battery or accumulator, and whose ferromagnetic properties differ according to their chemical constitution. The mesasurement method in which this device is used is based on the consecutive application to the excitation circuit of at least two different voltage amplitudes at the same frequency or two different frequencies at the same voltage amplitude.

A method of predicting battery test results includes using a battery test computer to predict a battery test result for a battery undergoing testing. The battery test computer comprises a tangible, non-transitory computer-readable medium storing a battery test management system implemented as one or more sets of instructions. The battery test management system includes a predictive module configured to predict the battery test result using less than all data required for the battery test to be complete, a validation module configured to validate the prediction, and a training module configured to re-train the predictive module based on results generated by the validation module. The battery test computer also includes processing circuitry configured to execute the one or more sets of instructions, and outputting, via a user interface, the prediction of the result and a confidence level associated with the prediction.
