This could be a electrical design problem with the grounding system. Back in the old days, the neutral and chassis grounding was connected together at the main service panel and then connected to a grounding rod. Later we use a insulated neutral bar and a non-insulated ground bar which ran separate ground wires to one ground rod.
In some installations we use one ground rod for the neutral and another for the chassis ground. The ground rods are then cross connected together 10 feet below ground. If lightning protection is used, then a secondary lightning arrester is used at the installation of the installation and is then connected to a separate ground rods that is located away as far from the electrical ground rods. Then a primary lightning protection is used, which is on a pole or tower that is located at a 45 degree angle distance from the installation it is protecting. A 50 foot lightning tower requires a 50 foot distance from the installation. Sometimes in a highly critical areas, we will install four lightning towers surrounding the area to be protected. Check to see if the electrical neutral and electrical grounds are isolated from each other. If not, then this is the fault of the manufacturer or installation methods.

The car went nuts and the 12v battery almost died. It couldn't even be towed because the supercharger cable couldn't be disconnected. ] Time and again, we are reminded the latest technology created by our brightest engineers are still no match to mother nature's smite. A YouTube video captured what happens when a lightning bolt strikes a Tesla Model S while it is parked outdoors and hooked up to a supercharger station. As you can see from the video below, the Tesla Model S lightning strike isn't exactly a direct hit, but it was enough to send a nasty shock to the car's circuits. According to Sarah Day, who uploaded the video from inside the white Tesla Model S, the incident completely disabled the electric car. "Lightning struck near my Tesla while supercharging. The car went nuts and the 12v battery almost died. It couldn't even be towed because the supercharger cable couldn't be disconnected," Sarah Day wrote in the Tesla lightning strike video description. In a later interview with Teslarati, Sarah explained the gauge cluster lit up with nine errors across the dash. The notifications include low charge warning, disabled functioned, and that the Tesla needed to be serviced. Unfortunately, Tesla service centers are not open on weekends so the extent of the damages in the Tesla is not clear. That said, it is a relief to know that Sarah was unharmed by the lightning strike. The Faraday effect allows a charge to distribute around the outside of a vehicle, protecting the occupants inside. Cars have been known to take on lightning strikes in the past, and mostly experience electrical, not mechanical failures, including the sensor systems, radio, GPS units, and power windows. Given that the Tesla is fully electronic and digitized, it is even more vulnerable to a lightning strike than a conventional car. Case in point, Sarah's Tesla was completely disabled.

But what looks to be a freak occurrence just captured on video shows that a bolt from the sky can, indeed, at least screw up your Tesla Model S. While the video doesn't show much beyond the bolt hitting the car, the wipers swishing back and forth, and the pitter-patter of rain, the video description from Youtube user Sarah Day fills us in on what happened: Lightning struck near my Tesla while supercharging. The car went nuts and the 12v battery almost died. It couldn't even be towed because the supercharger cable couldn't be disconnected. She went on to explain in a comment that the whole 'PARKING MODE DISABLED' bit was actually from the dashcam, not the car itself, and in an interview with Teslarati went on to detail the Christmas tree of warning lights now emanating from her dashboard: I heard the crash, and just a second or two after about 9 errors popped up on the dashboard. Some of them were low charge warnings, saying it would disable some functions. Others were on how the car needs to be serviced. I was also getting that the car can't be charged, and that the 12 volt battery is low. Which sucks. The 12-volt battery eventually shut down, too, and with it, the car's touchscreen system. The tow truck driver eventually got the 12-volt system up and running again, but it still took a few attempts. Sarah went on to detail how Tesla's support team was supremely helpful, but it was odd that the charging port wouldn't come undone. Just as well, the Supercharger fast-charging system is supposed to have a number of internal systems to protect against a sudden power surge. Though it's unclear if, in this case, a shot of lightning was powerful enough to overwhelm even those. This is an incredibly odd development from a Tesla Model S, reflecting an interesting (if rare) vulnerability for the electric car. What looks to have happened, just from what we can see here, is that the Model S may have suffered an indirect, rather than a direct lightning strike. If the bolt landed right on the roof, nothing may have happened, much like how the body of any other car works as a Faraday Cage. But it appears as if being connected to a Tesla Supercharger somehow gave the surge of electricity a line in to the car's internal systems. So you'd basically need to be charging your car, at the same moment as a lightning storm is overhead, and you'd somehow need to get a bolt to hit your supercharger system. So, like I said, pretty unusual. And even weirder, it was captured on video. Today is just a very weird day. We don't know exactly what happened for sure yet, but we've got a note in to Tesla, and will let you know if we hear back.
