Abstract
A method and apparatus for evaluating CEW performance, in particular by evaluating a battery pack condition state via direct or indirect means. A two-tier load test for a CEW battery pack and an indirect wireless spark analysis tool are disclosed.
Claims13
A method of evaluating performance of a CEW energy cell comprising:
- inserting a CEW energy cell into an input port of a portable test device;
- performing a two-tier DC load test on the CEW energy cell by sequentially applying at least two different loads to the CEW energy cell, including a low constant current load and a high constant current load;
- evaluating a voltage signature under the two-tier load test;
- determining at least one internal resistance value based on said voltage signature;
- and
- outputting at least one indicator relating to CEW energy cell status based on said determining.

A method of evaluating performance of a CEW energy cell comprising:
- performing a spark test with the CEW wherein a pulse train of high energy sparks is generated by the CEW;
- receiving with a wireless receiver a pulsed, a spark test signal emitted from the CEW during the spark test;
- providing a pulse shaping circuit and modifying the spark test signal with the pulse shaping circuit;
- calculating the pulse duration between each pulse based on an output from the pulse shaping circuit;
- and
- evaluating a condition of the CEW energy cell based on calculated pulse durations.
