Why Electric Vehicles?

4

Plug-in Hybrid Electric Vehicles

Powered by two energy sources: battery and an internal combustion engine

Electric driving range: 12-60 mi (unlimited overall range)

Eg: Chevy Volt, Toyota Prius Plug-in, Fisher Karma

Battery Electric Vehicles

Powered 100% by battery energy

Electric driving range: 100-300 mi

Eg: Nissan Leaf, Tesla Roadster, BMW ActiveE

CSU – Nor’wood Development partnership

Installation of EV charging stations in Colorado Springs service territory

Development and communication of customer marketing material and education on the benefits of electric vehicles

Collection of data on charging station usage to better understand demand on distribution system

On-going industry research and active participation in federal working groups (SGIP) for future planning

Efforts at CSU

How do we transition from our current state to the envisioned future state?

Smart Grid Interoperability Panel (SGIP) initiated by the US NIST is developing a framework for a staged evolution of all key areas within the PEV industry

Efforts at the Federal Level

Passive charging control that would lead to “dumb charging” and blown out

transformers

Smart charging and discharging in an intuitive and transactive grid that is ubiquitous, highly reliable

and secure

Initial State Envisioned Future State
