Why Tesla, GM And Other EV Companies

Have A Fire Problem 

"Electric vehicles provide a path toward a greener future, but they can be especially dangerous when they catch fire. While car fires are nothing new and internal combustion engine car fires are also a problem, lithium-ion battery fires are extremely volatile and challenging to put out, and there are few resources out there to help firefighters. In addition, car makers like GM, Ford, Hyundai and Tesla have had to do costly recalls due to fire risk. CNBC explores how automakers and firefighters are going to deal with EV's fire problem."

Top Barriers to Purchasing an Electric Vehicle: Volvo Car USA/The Harris Poll

"The top barrier among all drivers was running out of power (58%), followed by low availability of charging stations (49%) and then initial vehicle costs (48%). For existing EV owners the top barrier was initial vehicle costs (40%), followed by running out of power (38%) and then low availability of charging stations (30%)."

What causes sudden fires in Electric vehicles and how it can be prevented

"Speaking about the major factors behind damage caused to electric vehicle batteries, he said that it could be thermal abuse(high or low temperature variations), mechanical abuse(accident or crash) and also electric abuse(overcharging and deep discharging cycles). "

Motor 16. Autonomy problem in Mercedes EQS.

"So we drove with few concessions using the Sport mode on many occasions to give us more joy and feel the maximum strength of the Mercedes EQS in the quick supports. 26.9 kWh/100 km to arrive with 6% battery, 15 km extra and the anguish in the body that made us circulate the last 20 km without exceeding 80 km / h and in 'panic' mode. Where are the 741 km announced? The 16.6 kWh/100 km that we would have to achieve outside the city is very difficult for me at a safe speed, without ever letting up on the accelerator.

That in a car of its potential and behavior, seem to me unworthy and obscene". (Original text in spanish)

So, why do EV batteries catch fire?

"Today, most EVs charge blindly. These modules hold 2-3kWh of energy & are managed by obsolete analog BMSes that are dumb. They are no smarter than an MCB. If a certain cell is acting rogue, current BMSes have no intelligence on how to manage it, leading to an overcharging, dendrite build-up, and eventual thermal runaway. "

Cars online trend study. "Range anxiety"

"Throughout the customer lifecycle, but particularly in

the interest phase, many consumers feel inadequately

informed about areas that are important to them, especially

charging and batteries. This lack of information, and the

resulting reinforcement of negative feelings such as range

anxiety, could cause them to lose interest and switch back

to buying ICE cars."

Americans Cite Range Anxiety, Cost as Largest Barriers for New EV Purchases: Study

By a margin, the largest reason that consumers have avoided purchasing an electric car is range anxiety. That is, 58 percent of drivers are afraid that they will run out of power before being able to charge their vehicle, while another 49 percent fear the low availability of charging stations.

A comparison of battery and fuel cell electric vehicles 

"In the longer term, fuel cell technology maycross the finishing line,

at least for specialist use cases such as trucks. For at least the next

decade, though, batterydriven technology will likely retain its place on the victor’s podium."
