Do busbars affect battery thermal behavior?
Therefore, to ensure the realism of the thermal behavior simulation and the reliability of the subsequent thermal management, there is an urgent need to conduct in-depth research on the influence of heat production and heat transfer of the busbars on the battery thermal behavior.
What happens if a busbar contacts a battery?
Since the busbars contact directly with the battery electrodes, they can transfer heat to the battery, which lead to a local temperature rise in the battery electrodes and the upper part of the battery. It leads to a deterioration in temperature homogeneity [ 37 ].
Do high voltage battery busbars fail under combined mechanical and electrical loads?
Low Volt. Low Volt. 4. Conclusion The failure behavior of high voltage battery busbars under combined mechanical and electrical loads was experimentally investigated using different indenter geometries. The sharp indenter geometry was the most critical in terms of force and penetration until short circuit.
What is the difference between a battery electrode and a busbar?
Compared with the battery electrodes, the current density, heat flow density and temperature of the busbars are greater [36 ]. Since the busbars contact directly with the battery electrodes, they can transfer heat to the battery, which lead to a local temperature rise in the battery electrodes and the upper part of the battery.
Does the length of the busbar affect battery temperature uniformity?
Compared with the maximum temperature and maximum temperature difference, the variation of the average temperature and heat production with the length of the busbar is not significant. To improve the battery temperature uniformity as much as possible, the length of the busbar is finally determined to be 32 mm.
Are busbars good thermal conductors?
These should be a physical clip that is designed for the life of the pack and considers all of the above points and all environmental inputs. Busbars are good electrical and hence good thermal conductors. This means they can conduct heat away or to other components.
