E-buses in Germany a “fire hazard” as batteries can heat up to 1000°C. German cities taking vehicles out of service as a precaution.
Even after years of fine-tuning, electric vehicle manufacturers still seem unable to get e-vehicle technology to work as safely as it needs to for personal and public transportation.
German media, for example here, report that currently electric buses are being withdrawn from service in cities because they pose a fire hazard. Earlier in June of this year in Hanover, Germany, a major fire destroyed nine buses belonging to the Üstra transport company and so the company took the remaining buses out of service until the exact cause is determined.
“Not just the case in Hanover, it is becoming increasingly common for electric vehicles to be removed from service in cities, and the reasons are often down to a common cause: Fire safety,” reports the online MK.
Stuttgart withdraw buses from service after fire
The Stuttgart transport authority also took buses out of service after an electric bus fire destroyed 25 vehicles. The MK also reports that the city of Regensburg also removed the same kind of electric bus from service for fear of fire.
According to the MK, the problem is the extremes heat generated by the vehicle’s batteries, which can reach temperatures of 1000°C due to “thermal runaway”.
15-meter safe parking distance
“In the process, the lithium-ion batteries release energy in an uncontrolled manner,” reports the MK. “For the same reason, electric cars also repeatedly catch fire. The first e-cars are now only allowed to park at a distance of 15 meters because of the risk of fire.”
Also in China e-buses were recorded bursting into flames as they charged:
Even e-scooters can burst into flames. The following example also shows how difficult it can be to extinguish e-vehicle fires.
