Development of a Measurement Control System for Thermal Characterization of Lithium-Ion Batteries

In this work, general control algorithms for measuring the specific heat and heat generation of power lithium-ion batteries were developed and presented. These algorithms were implemented in the battery measurement system including the thermostat chamber, DC power supply and data acquisition system. This integrated system can systematically control the experimental instruments and calculate the battery's specific heat and heat generation instantaneously, leading to significant reduction in experimental procedures and optimization of different test methods. The workability of the battery measurement system was demonstrated with pristine and aged battery samples.
