Evacuation warning lifted in Otay Mesa battery storage facility fire

The fire at Otay Mesa’s Gateway Energy Storage facility that has smoldered for nearly two weeks has begun to settle down, prompting Cal Fire to lift a remaining evacuation warning for the area on Tuesday.

In a final update posted to X, formerly Twitter, Cal Fire said crews remain actively engaged in monitoring fire risk as the storage facility’s managers and contractors work to stabilize the site’s lithium-ion batteries, which are believed to have been the source of the fire.

Cal Fire officials noted there has been no instances of thermal runaway — or a chain reaction in a lithium-ion battery causing it to create heat faster than it can dissipate, which can lead to a fire — over the last three days.

Fires been burning for two weeks now. They hope things are under control but the next geostorm will likely reignite this fire.

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

Proof Electromagnetic radiation is causing EVs to go out of control and spontaneously combust.

4). Among the data records during the accidents according to the background data of the crashed vehicles or the data of on-vehicle terminals, the position values of most accelerator pedals were very high(99%) while the values of brake pedals were 0% or only non-zero in very limited moments (see Fig. 1 and Fig. 2).

Continued very high accelerator pressure with no braking is how you differentiate SUA from pedal misapplication.

In  recent  years,  there  have  been  numerous  out-of-control  accidents  of  electric  vehicles.

Occasional fault of electronic control unit caused by  electromagnetic interference

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.
