Firefighters Extinguish Tesla Fire at Cumberland County Gas Station

On Monday afternoon, firefighters in Cumberland County responded to an emergency involving a Tesla vehicle fire at a local gas station. The incident occurred around 5:50 p.m. at the Sheetz gas station located at the intersection of Market and Cumberland Parkway.

According to reports, Upper Allen firefighters were summoned after receiving multiple calls about a vehicle fire at a charging station on the premises. Upon arrival, Squad 23 quickly deployed firefighting equipment, stretching a hose line across South Market Street, which necessitated a temporary road closure.

The first responders managed to control the blaze and cool the electric vehicle’s battery, preventing further danger. Assistance was provided by other departments who helped manage traffic and contain any hazardous spillage or runoff.

The area was secured, and crews remained on-site to monitor the situation for potential re-ignition of the fire until the damaged vehicle was safely towed away. Fortunately, there were no injuries reported from the incident.

The dangers of EV charging stations around gas stations. If your EV spontaneously combusts while charging it could ignite the gas at the gas station making the situation far worse than simply a vehicle on fire. This shouldnt be a likely scenarion given that gas stations have safeguards in place to prevent gas in tanks from ignititing but those scenarios do not factor in EV fires which burn hotter for longer than say a cigarette igniting some fumes.

========================================

How does EMF cause lithium batteries to experience thermal runaway and thus spontaneously combust? One of two main ways:

#1 - Overcharge/Discharge

With various impressed external magnetic field intensities an effect was noticed on the charge and discharge curves as well as the charge and mass concentrations within the batteries. With the two-dimensional model starting from 0mT and going to 1mT had the effect of discharging the battery faster and charging the battery faster. With the two-dimensional model starting from 1mT and going to -1mT had the effect of charging the battery faster. In either case an effect on the various characteristics of the battery were studied. With the experiments conducted on the two types of batteries the effect was more profound than subtle. Discharge times were twice as fast and charge times were equally
affected. With the smaller batteries they all generally charged faster under the presence of a magnetic field due to more uniform penetration. In the presence of the field they also discharged faster. The larger batteries would not see the same uniform penetration because only a small area of the battery sees the center of the coil it is placed on

In this dissertation, they found that external magnetic fields significantly increased charge and discharge rates in individual lithium battery cells; like shown in the following image. They also found that smaller batteries were impacted to a greater degree than larger ones. This is likely a reason Tesla is switching to larger battery cells in addition to employing magnetic attenuating honeycomb sandwich battery pack.

#2 - Stimulation of Dendrite Growth

Thermoelectric current causes asymmetric growth pattern of dendrites.

thermoelectromagnetic convection occurs in the vicinity of the solid-liquid interface, and vortices are generated between dendritic arms. It is shown that the thermoelectromagnetic convection has a major influence on dendritic morphology.
