Tesla Inc (NASDAQ:TSLA) has provided customers fleeing Hurricane Irma with a free software update that extends the battery capacity of their electric vehicles.
The temporary update added around 30 to 40 miles to the driving range of the 75-kilowatt-hour Model S sedans and Model X SUVs.
“Cars with a 75-kilowatt-hour battery pack were previously software limited to 210 miles of driving range per single charge and will now get 249 miles, the full range capacity of the battery,” the company wrote on a blog.
The emergency measure came after a Florida-based customer requested a temporary upgrade to help flee Hurricane Irma.
People were ordered to evacuate their homes before the hurricane hit Florida Keys on Sunday but many reported troubles with leaving the area due to traffic jams, empty petrol stations and expensive flights.
Before reaching Florida, the hurricane had devastated 10 Caribbean countries and territories, killing about 23 people.
Tesla introduced its cheaper Model X and Model S vehicles last year with an 75 KWH battery that was software locked to use 80% of that available power. Drivers could unlock extra battery capacity with an update for an extra US$3,000.

"Those measures will certainly bring profound changes for our car industry's development," the country's vice minister of industry, Xin Guobin, told Xinhua.
Fortune’s David Z. Morris said Telsa could be a big winner in this development as it makes headway in the Chinse market with the rolling out its lower priced Model 3 sedan.
