METHOD FOR DEFINITION OF HEAT INPUT FROM CHEMICAL SOURCES OF CURRENT Russian patent published in 2018 - IPC G01K17/00 H01M10/48 

FIELD: measurement technology.

SUBSTANCE: invention relates to the field of metering of heat and can be used in experimental studies of temperature and energy modes of electrochemical cell. According to proposal, an experimental evaluation of heat flow parameters from the current source is carried out to determine the desired heat input. In this case, in contrast to the known methods and methods for generating and estimating required heat flux parameters, the test sample of the current source is used and cheaper and fire and explosionproof model of it with internal heaters of adjustable power that simulate the temperature regime of current source, which is analog of the test sample of current source according to the conditions of heat exchange with the environment. To implement this method, an installation that includes one or more test chambers equipped with devices for simulating heat exchange between the test sample and the environment, means to form operational modes (discharge and charge) of the source and temperature measuring means (temperature sensors) is used. During the experiment, a test sample of the current source is placed in the test chamber of the installation, on which the investigated operational conditions are realized under different conditions of interaction with the environment, and then the above-mentioned mock-up is placed in the test chamber, for which the required conditions of interaction with the environment are repeated, and by means of heaters installed inside it, the temperatures of external surfaces of the layout are maintained, equal to the temperatures of the corresponding surfaces of source under test when the operating conditions under investigation are realized, at the same time, the current operating parameters of said heaters are measured to estimate the amount of heat that they generate, which determines the desired heat input.

EFFECT: providing the ability to determine heat input from chemical sources of current in various modes of operation and placement conditions, simplifying the design of measuring equipment and ensuring safety of testing.
