Creating a Superstar Charging Location at the
Ventura County Government Center
Having all of these elements in one place creates a big opportunity. It means that this could become a showcase for evaluating and demonstrating different types of EV adoption and development charging strategies. This showcase would then be used to encourage similar developments at as many places as possible including both public and privately owned locations.
The County Center has all the elements it takes to become a superstar example of a charging location. It is a major destination in the county that is adjacent to a busy shopping district. It is a major workplace with close to 3000 parking spaces. It is an ideal location for a fast charger with several sources of 480 volt power around and adjacent to the campus. It has a fleet maintenance location in one corner of the site as well as being the home of a Sheriff’s department fleet.

The ground work for creating such a show case is already in place. The Fleet Manager Dennis Scamardo has already done a preliminary round of site analysis and charging needs. He has also established a personal leadership role by having driven a Chevy Volt starting two years ago.
• Ten hours of charging provides 40 miles of charge.
• Fourteen hours provides close to 60 miles of charge.
• Weekend charging on 110 would fully charge most AEVs.
The County Facilities Manager Steve Morgan is using that information in his site management and improvement planning. He is laying conduit in parking lots at every opportunity in preparation for implementation. He is also preparing a large scale Photo voltaic project that would integrate with a charging system and help reduce peak demand concerns.
The Ventura County Air Pollution Control board and staff are on board and helping with Stan Cowan leading the way. They have chargers at the VCAPC offices adjacent to the Center.
The Center has three convergent destination charging roles it can play. It has jury duty participants spending four to eight hours a day. It has numerous public meetings that last one to four hours. It is adjacent to professional office buildings and to banks and shopping. Each of these is an opportunity to provide charging station support to encourage EV use.
The utility companies have demand meters that are installed with all customers that have over a certain demand level for electricity, which in the case of Southern California Edison is 20 kW at any given time. The demand meters are called fifteen minute meters because the meters capture discrete 15-minute intervals of energy use. The meter is reset when it is read.
Eight hour visitors like those people on Jury duty could be provided AC Level one 110 volt outlets while on duty. These would provide up to 40 miles of range during and eight hour period. This would start with six to ten chargers in one part of the Jury Duty area in parking lot A.
Those visitors attending meetings that will last longer than an hour and up to 4 hours would be well served by having AC Level 2 chargers. These would be well positioned in the 4 hour parking area between the Administrations building and Telephone Ave. That location would also be the closest one to the banking and shopping area. Having one or more of these in the jury Duty area would also be suitable. It might be a good idea to limit these to four hour parking as well. This would encourage the jury duty people to use the Level 1 charging.
The primary role of the workplace charging is to provide the extra margin of error for people with AEV’s that have 80 mile ranges, referred to as AEV 80’s. These vehicles will handle most people’s commute needs with just the full charge they would normally have in the morning. Giving people with one of these vehicles a Level one 110 volt plug to charge with at work would provide 40 to 50 miles of range for a full 8 to 10 hour day at work. Adding that charge to the full charge in the morning would provide an AEV 80 owner with 120 to 130 miles total range each day. That is three times the national daily average miles traveled. This would allow employees to use their AEV 80 for work related uses without compromising their drive home.
This location is one of the largest concentrations of professional employment in the City of Ventura. It is a prime situation for workplace charging. This is attributable to both the number of employees, the presence of a good number of middle and upper level management, and the geography of the area. The management staff would have the resources to become EV drivers. The geography puts almost all commutes within an 80 mile round trip that is well within the reach of affordable all electric vehicles (AEV’s).
Level 1 110 volt chargers can provide 4 plus miles worth of charge in an hour. Light duty vehicle charging for both AEV and Plug in Hybrids (PHEV) would work as follows:
Fleets can use all levels of chargers to support their operations including DC fast chargers. The least cost solution would be determined by how many hours the vehicle can charge and how many miles it is driven in a day. The break basic down of what would be needed would be as follows:
The other option is to put chargers on light poles distributed around the campus. These could be included in all lots including the restricted parking in lot R. The use of power in this way is already being done to charge special use vehicles in service building lot.
There is a fleet presence in at least two places at the center. One is in the service building lot next to Hill Street and the other is in Lot E. Planning appropriate charging in these areas could serve multiple purposes.
There are two ideas for pursuing Level one 110 volt plugs for employee charging at the Center. One is to put in 6 to ten chargers in one area. Both parking lots E and F would be well suited to this for several reasons. Parking lot R may have the least cost solution to this due to the power availability and the parking being adjacent to the landscaping.
Medium duty vehicles would get around half this level of charging from the ten and fourteen hour times specified.
Destination Charging
Workplace Charging
Both of these options would make good workplace charging demonstration projects.
Fleet Vehicle Charging
A DC Fast Charger located in Parking Lot E would serve this function well while providing support for the fleet at the same time.
One fast charger in Ventura would cover the regional charger function. The County Center is an almost idea location as it would provide that function for all communities around Ventura including Oxnard, Camarillo, Santa Paula, Fillmore Ojai, Carpinteria and Newbury Park. One fast charger in Thousand Oaks would cover the rest of Ventura County except county line on PCH and the Naval Base.
County Center location is accessible to service the four main transportation corridors including both the main highways 126 and 101 as well as the corridors along highways 118 and the Pacific Coast Highway (route one). It is positioned to provide a fast charge that would get people to Santa Barbara from Santa Clarita, from all of the San Fernando Valley and from the Westside and Malibu.

In addition a fast charger at that location would be a workplace charger that would solve the needs of the 3000 parking space campus and all the surrounding businesses. That could encourage hundreds of all electric vehicles (AEVs) for people in that area. A handful of Level 2 AC charging stations at the same location would help the plug-in hybrid owners as well as giving fast charged AEVs the opportunity to top off from 80% to 100%.
Location is Key to Corridor Fast Charging
Having both a fleet charging and a workplace charging situated in one location is a perfect compliment. The Fleets typically charge at night and the workplace charging is done during the day. This is one reason to locate the work place charging near the fleet areas. It is also a reason to locate the fast charger near the Fleet service area.
DC Fast Chargers would support fleet charging as well. This includes both midday top off charges as well as regular charges up to 80 percent of charge. Filling a vehicle to 80 percent of charge on a fast charger and then putting it on a 110 plug overnight would assure 100 percent charge every morning in almost all cases including medium and heavy duty plug in vehicles.
Level 2 chargers would fully charge most AEV passenger vehicles in ten hours with 80 miles of range
Combining both corridor charging for four corridors with workplace, fleet and destination charging for one of the most active employers and destinations in the city would be a huge win for EV's. It would become a stellar showplace for all three of these charging needs and a clear statement of how easily EVs can be supported with a well-planned infrastructure. This would set the standard for rural county EV support.
