In the info sent to its customers, the company explains that free Supercharging should help Tesla owners safely relocate. According to media reports, most of the Superchargers are located along motorways and usually are unaffected by floods.
Media reports about a three-digit number of deaths and over a thousand missing as the result of the catastrophic flood.
Standard fees will probably return once the situation will stabilise, as in the previous cases of natural disasters when Tesla tried to support its customers.
Multiple other manufacturers are also trying to support customers. We saw reports that companies offer free rentals, provide vehicles to Red Cross/ authorities or financial support.
Electricity is usually returning first in the areas affected by natural disasters, which means that in general, electric vehicles should remain operational, but of course, the destroyed infrastructure requires time to be repaired.
In the future, one of the most important advantages of electric vehicles with large battery packs might be the power export feature - like the one announced for the upcoming Ford F-150 Lightning.
With an ability to power up external devices/tools and even an entire house for days, EV owners would be able to more seamlessly deal with power outages in nearby areas.
