Natural Sources of EMI that can cause EVs to go out of control

The most common cause of Natural EMI includes:

Lightning
Solar Magnetic Storms
Earth’s Magnetic Field Flux
Cosmic Radiation

A.

When the solar wind’s magnetic field turns southward, the dayside, or sun-facing side, of the magnetosphere contracts inward. The back end, called the magnetotail, stretches out like a rubber band. When the stretched magnetotail finally snaps back, it starts to vibrate, much like a spring moving back and forth. Bright auroras can occur during this stage of the substorm

Is the magnetic oscillations seen within image #1 caused by the earths magnetotail vibrating? This disturbance then leads to aurora and magnetic activity at the earths surface.

B.

These new observations allowed scientists to directly link specific intense disturbances in the magnetosphere to the magnetic response on the ground. A paper on these findings was published in Nature Physics on Sept. 12, 2016

During solar storms and increased subsequent geomagnetic activity, electromagnetic radiation is seen at the earths surface that can then interfere with the electronic control system and wiring of EVs passing by. This can then lead to the EV sending and receiving the wrong instructions leading the EV to perform actions that the driver did not instruct it to do. While there are electromagnetic compatibility requirements mandated for automotive companies to meet, they are simply not sufficient enough to withstand some of the surface EM radiation they operate through. That leads to the out of control Eve we see in the media.
How EM radiation causes incorrect operation is explained in more detail in the following study:


How external EMI can cause Electric Vehicles to go out-of-control

C.

External  electromagnetic  interference  refers  to  that  caused  by electromagnetic  radiation  of  various  electrical  facilities  including  the  high  voltage  transmission  line, broadcasting  TV  devices  and  radio  communication  equipment  as  well  as  natural  phenomena  such  as lightning.

Electromagnetic  wave  interferes  the  electric  control  system  of  automobile  through  wiring  harness and  car  body to  make  it  hard  to  perform  or  even send  wrong  instructions leading  to  wrong  actions  of various  actuators,  affecting  the  safety,  reliability  and  stability  of  automobile  driving.  The electromagnetic  interference  affects  the  automobile  electronic  control  system  mainly  in  two  ways:  one is  to  affect  the  input  signal  of  the  sensor  of  the  electronic  control  system,  causing  distortion  and resulting  in  electric  control  signal  where  the  ECU  output  does  not  match  the  driver's  intention,  which leads  to  the  wrong  operation  of  the  actuator;  the  other  is  to  interfere  the  ECU  output  signal  to  result  in its deviation,  misleading the operation of  the actuator.

The Accident

June 11th, 2023 ~7 a.m. UTC/ 1 a.m. MST

3 people killed in Tesla rollover in southeast Edmonton

D.

According to police, a 2023 Tesla carrying six adults was travelling eastbound on Ellerslie Road at very high speeds around 1 a.m. The vehicle lost control, rolling several times off the road, police said.

Two men and one woman were pronounced dead at the scene. Paramedics treated two other men and took them to hospital in critical condition. Another woman was taken to hospital in serious but stable condition.

80. June 11th (53.4248710, -113.3693026)

This was the 80th out of control EV and I believe the 76th Tesla accident this year. The accident occurred in a way to suggest that this Tesla experienced both SUA and veered off the road before flipping. Both conditions seen in a majority of the 76 Tesla accidents this year and so many accidents before it.

As more EVs hit the road the odds of this happening increases at a rate faster than sales of vehicles. This is because the problem is compounding as the chances these EVs will operate through an area experiencing greater EM radiation increases as more EVs are on the roads. This puts more drivers, their passengers, and the public at large in greater danger.
This of course assumes that surface magnetic activity behaves the same during such storms. However the earths magnetic field is weakening and thus the conditions seen on earth will change with it making it near impossible for engineers to properly account for the EMI the vehicles will experience.

The joys of EMI in electric vehicles! Who doesn't love the symphony of glitching audio systems, malfunctioning GPS navigation, and antilock braking systems that seem to have a mind of their own? It's like a thrilling rollercoaster ride every time you step into an electric car, never knowing if you'll reach your destination or end up in a wild goose chase!

And let's not forget about those advanced driver assistance systems (ADAS) that provide you with a constant stream of excitement. One moment, they're detecting obstacles and guiding you safely on the road, and the next moment, they're having a full-blown existential crisis, unsure of their purpose in life. It's like having a temperamental co-pilot who's constantly playing pranks on you!

Oh, the tales of recalled systems in Teslas! It's practically a rite of passage for every system to experience a little glitch here and there. From the air-bag controls that decide to take a nap when you least expect it to the collision warnings that seem to have a fondness for false alarms, every system wants to leave its mark on the recall list. It's like a game of "Guess Which Component Decides to Misbehave Today"!

But fear not, my friend! It's all part of the electrifying EV experience. Who needs predictable and reliable systems when you can have a thrilling adventure with electromagnetic compatibility issues? It's like living on the edge, never knowing if your car will gracefully glide or spontaneously dance its way down the road.

So, buckle up and embrace the excitement of EMI in electric vehicles! It's a wild ride full of surprises and unexpected quirks. Just remember to keep your sense of humor handy because you never know when your EV will decide to unleash its mischievous side and give you a story to tell!
