Charging the heat battery refers to the process of adding thermal energy to the storage medium. The amount of energy supplied to the heat battery is determined by a charging function, which calculates the electric charge input to the system. The process of electric charging is an exercise of balancing.
The standard deviation coefficients of the key parameters (i.e., heating time and thermal runaway temperature) in the thermal runaway test results were used to evaluate the repeatability of the tests. Furthermore, a screening method for the heating power was further designed.
A method is given to determine the optimum heating power to trigger thermal runaway. Heating time and temperature were used to judge the repeatability of the method. The heating power was calculated using the rated energy and weight of the battery. The formula was validated using NCM/C cylindrical lithium-ion batteries.
Heat batteries are units designed to store significant amounts of heat for later use, for example storing heat generated at night for use during the following day to provide space and water heating. The main factors affecting their performance are the amount of heat they can store and how well they can retain this heat.
By fitting the data for Pheat / mcell and Ecell / mcell of the four ternary cylindrical lithium ion batteries, a linear relationship between Pheat / mcell and Ecell / mcell was found and the equation for calculating the optimal heating power was obtained, i.e., P h e a t = − 15.41 E c e l l + 4.72 m c e l l.
