The Seabrook Board of Selectmen, along with Planning Board Chair Jason Janvrin, Building Inspector Steve Zawlewski, Town Manager Bill Manzi and Deputy Fire Chief Koko Perkins, gathered to join DDR in cutting the ribbon on the new Tesla Super Charging Station located at Seabrook Commons. Tesla has installed more than 550 Super Chargers world wide, but only four in New Hampshire. These Super Chargers provide 170 miles of range in as little as 30 minutes.
From the Tesla Website:
Superchargers consist of multiple Model S chargers working in parallel to deliver up to 120 kW of direct current (DC) power directly to the battery. Typically, Model S uses its onboard charger to convert alternating current (AC) from a wall charger to DC that’s stored in the battery. As the battery nears full charge, the car’s onboard computer gradually reduces the current to the optimum level for topping off cells.
Charging each cell is like filling a glass of water without spilling. As the glass fills up, you reduce the flow to catch every last drop. In battery terms, this means reducing current in order to balance cell voltage, ultimately tapering down to a trickle as it nears full. The resulting charge profile is why we recommend charging to 80%, which is typically enough to reach a neighboring Supercharger station.
Using a Supercharger is as easy as using a Wall Connector. You simply plug in, walk away and in approximately 30 minutes you have enough range to get to your destination or the next station. Every new Model S includes Supercharging.
Engineered for Speed
Supercharging takes advantage of the unique battery architecture that makes Model S P85D the quickest sedan in the world. Accelerating from 0 to 60 mph in 2.8 seconds requires a strong draw from the battery pack to power the front and rear motors. The connections, cell chemistry, and battery cooling system are all engineered to move significant power out of the battery pack during hard accelerations and uphill driving.
Driving (discharging) and charging use the same systems to move energy out of and into the battery. Supercharging utilizes the car’s discharge capacity to flow a similar amount of power back into the battery pack through dedicated high voltage cables. The car’s onboard computer constantly monitors the battery during both driving and charging to ensure that Model S performs at its peak.
Model S is currently the only EV capable of charging at up to 120 kW, which equates to 170 miles of range in about 30 minutes.
The Planning Board worked with our Fire Department, Inspectional, and Tesla to bring this project to fruition, allowing this cutting edge technology to come to Seabrook. Our thanks to Jim Grafmeyer of DDR for setting up this ribbon cutting.
