6 FAQs about [Two battery packs fireproof]

What is the PHRR of a 3 3 battery pack?

For battery packs with 100% SOC, the pHRR of the 3 × 3 cell module even increases by about 8 times to 12 kW. For different cell packs with 0%, 50%, and 100% SOC, the pHRR also satisfies a power function relationship with a positive correlation. As the battery pack grows larger, surprisingly, it even reaches a maximum of almost 7000 ppm.

What is CFRP based battery case?

In addition, a CFRP-based battery case can save up to 40% of weight compared to aluminum and steel cases . Saudi Basic Industries Corporation (SABIC) is working on reducing the weight and cost of the battery pack of EVs using long glass fibers in a PP matrix with thinner and more crash-resistant properties .

What if battery pack size is less than 2 3?

For battery packs with 100% SOC, the pHRR of 3 × 3 cell module even increased by about 8 times to 12 kW. The content of toxic gas CO was evaluated by determining fractional effective dose (FED). It could be concluded that when the pack size was smaller than 2 × 3, the FED was below 1 for battery packs with 50% SOC and 100% SOC.

How many modules are in a battery pack?

The number of modules present in the battery pack varies with the desired storage capacity and specific battery technology/chemistry (nickel metal hydride (NIMH), Li-ion, sodium-sulphur, etc.), which in turn determines the range of EVs .

Can a cone calorimeter measure the fire hazard of battery packs?

In past studies, the cone calorimeter based on the oxygen consumption principle has been shown as an effective device to measure HRR during the combustion of batteries . In this work, as shown in Fig. 1, a cone calorimeter was used to study the fire hazard of battery packs of different sizes.

How much weight does a battery pack weigh?

Further, the range can also be affected by the curb weight of the vehicle. Capacity of the battery packs directly reflects on their weight, which is calculated to be 363, 672, 948, and 1267 lbs for 22, 44, 60, and 80 kWh, respectively [24, 25].
