The electrification of the vehicle fleet will result in an additional load on the power grid. Adequately dealing with such pluggable (hybrid) electrical vehicles (PHEV) forms part of the challenges and opportunities in the evolution towards Smart Grids. As the number of plug-in hybrid vehicles (PHEVs) increases, so might the impacts on the power system performance, such as overloading, reduced efficiency, power quality, and voltage regulation particularly at the distribution level. Coordinated charging of PHEVs is a possible solution to these problems. Our EV charging solution have the relationship between feeder losses, load factor, and load variance is explored in the context of coordinated PHEV charging. From these relationships, three optimal charging algorithms are developed which minimize the impacts of PHEV charging on the connected distribution system. The application of the algorithms to two test systems verifies these relationships approximately hold independent of system topology. They also show the additional benefits of reduced computation time and problem convexity when using load factor or load variance as the objective function rather than system losses. This is important for real-time dispatching of PHEVs.
Our Solution Provides:
Purpose Built for work place, Fleet EV and MTD Charging: Control Module centralizes access control, data recording and communications, significantly reducing hardware costs as well as ongoing monthly data charges.
Simple Operation with Multiple Access Control Choices: Drivers connect their EV and then enter the charger number and Charge Authorization Code in the keypad which starts the session. Usage data is paired with the driver’s code and transmitted to the Liberty server every 15 minutes, where owners can view usage records and prepare billing statements. It support a variety of access control and billing methods, including credit card, fleet fueling cards and HID access badges.
Open Standards For Communications and Demand Response: It uses the Open Charge Point Protocol (OCPP) communication standard which enables owners and operators to select from a range of aftermarket service providers and ensures competitive pricing.
monitors, records, transmits energy data for all authorized users: Incorporates "Revenue Grade" (.01 kWh accuracy meters to send usage data to solution main board for storage. Collects consumption data every 15min based on User ID charging events for desired reporting periods.
