6 FAQs about [Battery Pack Radiation Protection]
How to create a safe and reliable battery pack?
Creating a safe and reliable battery pack requires the use of monitoring and protection of battery cells.
Does insulating a battery pack reduce fire risk?
The heat transfer is blocked by the insulation layers, and the Tpe of the next cell is slightly reduced by heat exchange with the ambient environment through radiation and convection. Thereby, it can be concluded that the addition of the insulation layers reduces the average Tpe of the battery pack which reduces the fire risks for the battery pack.
What is the thermal conductivity of a battery pack?
The insulation layer has a slight effect on alleviating thermal shock, and the average Tpe of the battery pack without protective methods is approximately 865.5°C. With the addition of 1 mm insulation layer between neighboring cells, their average Tpe is at approximately 831.6°C, 829.5°C, 831°C, and 846°C for different thermal conductivities.
Can epoxy resin plates be used between battery packs?
In addition, adding epoxy resin plates of different thicknesses between battery packs can block the thermal conduction and radiation capabilities between batteries, prolong the thermal conduction process between different batteries, and effectively reduce the thermal runaway damage caused by lithium-ion batteries 5, 6, 7.
Why should the TR propagation of a battery pack be blocked?
This fast TR propagation process may cause more serious phenomenon of explosion. Therefore, the TR propagation of the battery pack should be completely blocked instead of just being delayed if possible. The lowest thermal conductivity, 0.02 W/ (m·K), shows the best performance in delaying the TR propagation in Figure 9 (d).
What is thermal runaway suppression for battery packs?
Design of thermal runaway suppression for battery packs. The function of the mica plate is to isolate the flames and high-temperature gases sprayed from the battery during a fire from damaging the upper shell of the battery, dispersing heat and preventing heat from concentrating on a metal shell that is prone to burning through the battery.
