Abstract

A method providing comprehensive information about the properties of a type of electrochemical batteries at all stages of batteries resource exhaustion at their utilization which (properties) are connected with the action of the corresponding (for this utilization) influence on the batteries is realized through acquisition of the experimental data that contains the comprehensive information about these properties, creation of the known and new relevant quantities (on the basis of the acquired experimental data and some relevant parameters of the batteries) that characterize these properties, and study of the functional behavior of the created relevant quantities.

Claims

1. A comprehensive research method of the properties of a type of electrochemical batteries at all stages of their resource exhaustion at utilization which (properties) are connected with the action of a specific for this utilization influence on the batteries and can be observed in the framework of a chosen parameter of this influence (the influence “

strength”

), parameters of the response, a parameter of battery exhaustion, and the capabilities of the measuring instruments used including the steps of;

carrying out a sequence of alternating discharges (influences) and recoveries (pauses) for each battery in a set of identical electrochemical batteries, with a number of long discharges the duration of which is determined by usage of some part of battery resource, with a number of initial short discharges and intermediate short discharges in each sequence, with increasing and decreasing influence “

strength”

in each discharge, with a main segment of each discharge having a constant value of the influence “

strength”

during the sequence but having different values in the sequences for different identical batteries of the set, with a recovery after each discharge, and with the end of the sequence occurring when the corresponding battery stops satisfying utilization requirements;

monitoring and recording the parameters of the response of the batteries to the influence during each discharge (influence) and each recovery (pause) for each of the batteries of the set;

creating the relevant quantities that could characterize properties of the researched batteries from different sides by means of different mathematical operations over the experimental data and relevant parameters of the batteries;

studying functional behavior of the created relevant quantities as functions of the real time, influence “

strength”

, utilization parameter, and response parameters;

creating and studying functional behavior of the new relevant quantities.

2. The method of the claim 1, wherein duration of the initial short discharges increases in each next initial short discharge in each sequence in the same way.

3. The method of the claim 1, wherein said number of initial short discharges equals one in each sequence.

4. The method of the claim 1, wherein duration of the intermediate short discharges increases in consecutive order in the same way between each two neighboring long discharges and after the last one in each sequence.

5. The method of the claim 1, wherein the number of intermediate short discharges between each two neighboring long discharges and after the last one equal one in each sequence.

6. The method of the claim 1, wherein said recording occurs during a time from the beginning of each discharge and recovery and also at the end of each discharge and recovery for all identical batteries of the set.
