6 FAQs about [Heat flux density of energy storage battery]

Where is the maximum heat flux generated in a battery?

Heat flux generated along the battery width is symmetric, and the minimum heat is located at the battery extremities. Along the battery height, the maximum heat flux is generated near the battery positive and negative electrodes. Also, the difference between the highest and the lowest heat flux increases with current rate.

Why does a battery have a higher dissipated heat flux?

Regardless of the heat flux sensor position on the battery surface, the higher the imposed current is, the higher dissipated heat flux is because of the increase of the molecular interaction and the kinetic of the electrochemical reaction.

How does distance affect the temperature distribution of a battery module?

The distance between two adjacent batteries has a greater impact on the temperature distribution of the battery module during high rate discharge, and monitoring the change of heat flux can predict the failure of the thermal management of the battery in advance.

How does discharge rate affect battery heat generation?

With the increase of the discharge rate, the total discharge heat generation of the battery gradually increases, and the increase amount of the discharge heat generation is approximately equal to the decrease amount of the total discharged electric energy of the battery.

What factors affect battery heat generation?

Various parameters influence the heat generation of LIBs, with battery temperature being affected by factors such as cooling and heating systems in the thermal management system, ambient temperature, battery thermal conductivity, heat generation, and battery heat capacity.

What is the average temperature of a battery?

An average standard variation of 0.16 °C was obtained for the local surface temperature measurements and 2.70 W m −2 for the heat flux densities. The battery surface temperature and local heat flux are employed as the index in estimating the performance, size and location of the cooling module.
