I see that they mercifully removed the totally backwards "How
supercharger works" portion of the linked article.
A bit of an embarrassment for the author, had they left it in.

How Safe Are Tesla’s Supercharger Stations?

Earlier this week, a private contractor was killed at a Tesla Supercharger
just one day before the location’s grand opening, which may prompt some to
wonder about the safety of these charging stations.
Few details have been released on the incident, which occurred sometime
Tuesday morning at the facility in Norfolk, Va. Reports indicate that Steven
Weaver, 32, was at the Supercharger that morning working on equipment. About
3.5 hours after witnesses saw Weaver walking in and out of the fenced-in
equipment area, someone called 911 to report the death.
“During the installation process at our new Supercharger station in Norfolk,
there was an accident involving an electrical contractor,” a Tesla
representative told local news station WAVY.com.
Officials have not elaborated if the contractor was electrocuted or
confirmed any other details about the accident.
“Due to an accident during the last stages of our Supercharger installation,
we will be postponing our grand opening,” said Will Nicholas with Tesla. The
carmaker hasn’t announced when the grand opening will be rescheduled for.
We haven’t been able to find any other reports linking Superchargers with
deaths or serious injuries of either contractors or people charging their
cars. With many people using Superchargers across the country without
incident, it doesn’t appear that there is an underlying safety hazard at
these stations. All charging stations are required to meet national safety
standards, and according to Tesla, Superchargers are even safe to use when
it’s raining or snowing.
That’s partially because electricity doesn’t flow through the cord until the
car is ready. Once the Model S is plugged in, the car’s computer tells the
Supercharger to “turn on” and supply the electricity.
Despite its name, what drivers are actually using at a Supercharger station
is a heavy-duty cord; the charger itself is mounted on the Model S. After
plugging into the Supercharger, this cord supplies 120 kilowatts of direct
current (DC) to the vehicle. The vehicle’s on-board charger converts the
energy to alternating current (AC) and stores it in the lithium-ion battery
pack.
“Charging your electric or plug-in hybrid car is safe and easy,” AAA
explained. Electrified vehicle (EV) “charging equipment is tested and
certified by independent organizations such as Underwriters Laboratories,
CSA International, and Edison Testing Laboratories. In addition, EV charging
systems employ sophisticated computers and software that manage the charging
process while protecting both the user and the vehicle.”
