| Objective To research methods for measurement of thermal characteristic parameters of 10Ah ternary NCM lithium ion battery, provide a theoretical basis for the thermal management simulation of lithium-ion battery and solve the problem of thermal management of lithium ion power battery for manned submersibles under deep sea environment. Methods First of all, a precision measuring instrument was used to calculate the thermal conductivity of the battery in combination with the principle of heat transfer. Secondly, a high-precision adiabatic experiment box was built based on the control strategy of battery temperature and ambient temperature follow. In the adiabatic environment, the actual heat generated by the battery would be completely absorbed by itself, and there was no heat exchange with the environment. The specific heat capacity of the ternary NCM lithium ion battery was identified with a pulse test method in an adiabatic experiment box. Results The measurement results of the thermal property parameters had higher accuracy. The absolute error between the temperature calculation result and the actual temperature measurement result brought into the thermal model did not exceed 0.5℃. The average relative error was 0.0184. Conclusion The thermal characteristic parameter of the battery based on the experimental method can reflect the thermal state of the lithium ion battery, and the error between the measurement result and the actual value is acceptable. |
