Universal Electric Vehicle Charging for City Dwellers
Are concentrated hubs of DC fast chargers the solution to charging personal electric vehicles in the urban environment? Revel, a New York City-based electric transportation company, is testing the concept of EV charging Superhubs.
I recently visited the Revel Superhub in Brooklyn and it was impressive. The charging stations are located in an open parking lot at 467 Marcy Ave in the Bed-Stuy section of Brooklyn. There are 25 charging stations all wrapped in bright blue, the same color as the fleet of Teslas that Revel uses in their electric vehicle ride hailing service.
The Revel Superhub uses 25 stand-alone fast chargers manufactured by Tritium. The RTM75 fast chargers can deliver up to 75 kW according to specifications. The Tritium fast chargers came stock with both a CCS and a CHAdeMO connector.
Universal Chargers Adapted for Teslas
Revel has retrofitted all but three of the chargers with an off-the-shelf Tesla CHAdeMO adapter that allows Tesla vehicles to use the chargers. This is a clever work around to allow Revel to serve the Tesla market which comprises the majority of electric vehicles on the road right now. This is similar to what EVgo is doing with their DC fast chargers. [EVgo Adds Tesla Plugs to DMV Area Fast Chargers]
The EV charging Superhub is open to the public 24/7. In contrast to many other fast charging sites in New York City, there is no entrance fee or cost for parking. All you pay for is the electricity itself which is $0.39 per kilowatt hour plus tax.

Near I-95 at Konterra and Van Dusen Roads
A new Supercharger is under construction at the Royal Farms Store at 6901 Van Dusen Rd, Laurel, Maryland. This will be a 250 kW (V3) Tesla Supercharging site and is expected to have eight stalls.
This site is less than a mile from I-95 and will be a more convenient alternative for travelers than the original Laurel, MD Supercharger that opened in 2016 at Laurel Towne Centre.
Construction of new Tesla Superchargers in the greater Washington, DC area has accelerated in the last year. Stay tuned for developments on this and other electric vehicle charging stations in the DC, Maryland and Virginia area.

Officials cut the ceremonial ribbon to open the new Howard County Courthouse yesterday. [map] The building is designed to be certified LEED Gold for environmental sustainability. Solar arrays on the roof and the adjacent field are projected to produce 1,177,500 kilowatt-hours of electricity per year which is roughly the amount of electricity for powering 141 homes.
Howard County Courthouse Parking Garage
A 682-space parking garage is located next to the courthouse building. The garage is equipped with electric vehicle charging stations. The Level 2 EVSEs are from EVBox and deliver up to 32 Amps each.
The new courthouse and garage are built on the former site of the Howard County Dorsey Building which hosted the first Howard County public charging stations. I attended the dedication ceremony of those charging stations on November 7, 2011. See: First Public Charging Stations in Howard County
There is no fee to use the charging stations and no authentication is required. Not sure if it will always remain free. There are gates and payment kiosks to pay for parking but they were not yet activated.

The Giant store at 8805 Centre Park Dr, Columbia, Maryland now has a pair of electric vehicle charging stations. The stations were installed by Volta Charging.
Free Charging – Supported by Advertising
These free EV charging stations are subsidized by selling advertising messages that are displayed on the large digital screens on each unit. Volta claims to be the world’s most highly used EV charging network.
Volta says their business model isn’t to make money from selling electricity to EV drivers. Instead, Volta partners with highly-visited retail locations such as grocery stores and retail centers where they can display advertising messages.
The Mall in Columbia, operated by Brookfield Properties, had the first Volta charging stations in Howard County. The Giant store at 7200 Cradlerock Way in Columbia got their own Volta stations a few months ago. White Marsh Mall in northern Baltimore County has eight Volta charging stations. Towson Town Center also has Volta charging.
Expect to see more of these free charging stations showing up at Giant stores in the coming months.
The Meadowood Regional Park in Lutherville, Maryland now has public electric vehicle charging stations. The BGE EVsmart stations were operational and in use by a Chevy Bolt EV on Saturday, January 30, 2021. Two dual-port Level 2 charging stations can charge four vehicles at once. The Meadowood Regional Park EV charging stations are located in the south east corner of the parking area just off of Falls Road.
Meadowood Regional Park is located at Falls Road and Greenspring Valley Road just north of the Baltimore Beltway (I-695) and the Jones Falls Expressway (I-83). Map link
According to the Baltimore County Department of Recreation and Parks, Meadowood Regional Park provides a variety of outdoor recreational facilities including:
- Six athletic fields (four lighted, one artificial turf)
- Three picnic pavilions
- A .8-mile paved walking path, with upper and lower sections measuring .4 miles each.
There are a number of take-out food establishments nearby at Green Spring Station, so you can grab a meal and enjoy a picnic while you charge.
The fee to use the Level 2 charging stations is $0.18 per kWh including 6% Maryland sales tax. The fees are subject to change with the approval of the Maryland Public Service Commission which regulates the utilities. Payment is via a Greenlots account.

Six Level 2 Ports
A public charging site is open at the Anne Arundel County Public Library at 269 Hillsmere Drive, Annapolis, MD. The BGE EVsmart utility owned and operated charging stations are energized as of January 20, 2021. There are two DC Fast Chargers and six Level 2 ports along the east edge of the parking lot. [map link]
The BGE fast chargers have a fee of $0.34 per kWh. The Level 2 charging costs $0.18 per kWh. Those fees are subject to change with the approval of the Maryland Public Service Commission which regulates the utilities. Payment is via a Greenlots account.
Two CCS/CHAdeMO Fast Chargers
The two 50 kW fast chargers are Efacec QC 45 units that are also used in some other BGE installations such as Westminster and Ellicott City. Having multiple fast chargers will help bolster EV drivers’ confidence. If one fast charger is occupied or inoperable, there’s another fast charger for back up.

Tesla Supercharging Station at Wawa
The Rehoboth Beach area now has its second Tesla Supercharger. An eight stall, 250 kW (V3) Supercharging station just opened at the Wawa convenience store by the intersection of Coastal Hwy and Rehoboth Ave. Ext. Map Link
This Supercharger is located less than four miles from the Lewes, DE Supercharger that opened about three years ago. The Lewes Supercharger is an eight stall station also located in the lot of a Wawa store. It’s a 150 kW powered station as compared to the 250 kW at the newer one in Rehoboth.
Why did Tesla build two Superchargers so close together? We don’t know. But consider this, the Wawa chain has three stores in that stretch of Coastal Highway that sell gasoline. There are at least six other gas stations in that section. Ultimately, electric vehicle charging stations will become ubiquitous. Areas like the beach, where tourists drive beyond the range of the charging station in their home, will be among the first areas that need to support a higher volume of people that need fast charging.
Rehoboth Beach already had many Level 2 EV charging stations to help support EV drivers visiting from out of town. There are two high-amp L2 stations at Surfside Park that were proposed in 2014 by the University of Delaware as part of a statewide network of EV charging stations in Delaware. There are also Level 2 charging stations at the three Tanger Outlets locations in Rehoboth Beach that were installed in 2015.

Potomac Edison Charging Stations Open in Hancock
Two new CCS/CHAdeMO Fast Chargers owned and operated by Potomac Edison opened today in Hancock, Maryland. The chargers are located in the parking area of Joseph Hancock, Jr. Primitive Park on Main Street. The two ChargePoint Express 250 Fast Chargers can deliver 62.5 – 125 kW based on power sharing. The cost is $0.30 per kWh and is set based on approval of the Maryland Public Service Commission which regulates the utilities.
Potomac Edison opened their first DC Fast Charger last week at the Deep Creek Visitors Center in McHenry, MD. We charged there on Saturday, January 2nd using a Tesla CHAdeMO adapter. Users can pay using a ChargePoint RFID card or App. The units are wrapped in blue Potomac Edison “EVDRIVEN” branding and the URL to their EV website is displayed on the front. A blue and white sign designates the area as “electric vehicle parking only while charging.”
Adds to Existing DC Fast Charging in Town
Hancock already has two Fast Chargers located a few blocks away at the Western Maryland Rail Trail Parking Lot. Those chargers are operated by EVI and were installed about a year ago with funding help from the Maryland Energy Administration’s Alternative Fuel Infrastructure Program. Those chargers are 50 kW and bill users with a flat fee plus by the minute rather than by the kWh.

Utility-Owned Public Charging Stations Open in Western Maryland
EV drivers have been waiting many years for CCS and CHAdeMO Fast Chargers to come to Garrett County, Maryland. In April, 2014, the Maryland Attorney General announced a $1 million grant program to build a statewide network of DC Fast Chargers that was supposed to extend from Western Maryland to the Eastern Shore. Unfortunately, the western portion never materialized.
In January, 2019, the Maryland Public Service Commission issued Order No. 88997 which allowed a pilot program of utility owned and operated public EV charging stations under the condition that they are located on property owned, leased or occupied by a state, county, or municipal government.
Potomac Edison has now opened their first Fast Chargers along with a Level 2 station at the Deep Creek Visitors Center in McHenry, MD. The two ChargePoint units are rated to share 125 kW of power between them. We successfully charged using a CHAdeMO to Tesla adapter on one of them on Saturday, January 2nd. While in the area, we spotted four other Teslas in and around McHenry. Teslas need a CHAdeMO adapter sold by Tesla or perhaps one of the new third party CCS adapters to use these ChargePoint units. Maybe these fast chargers will encourage drivers of Chevy Bolts and other EVs with CCS or CHAdeMO plugs to make the trek to Western Maryland in their electric cars.
Garrett County has the second lowest adoption of electric vehicles in Maryland according to an analysis of Plug-In Vehicle Adoption. Garrett County has 15 all-electric and 5 plug-in hybrid electric vehicles registered according to the latest data from the Maryland Motor Vehicle Administration. This means that most of the utilization of the fast chargers in McHenry will probably be from tourists and other visitors.
