City of Chicago and 350Green announce city-wide Network of EV charging stations, 73 DC fast and 207 Level 2

The City of Chicago has selected 350Green, a developer of electric vehicle (EV) charging networks (earlier post), to design, build and operate a network of 280 EV charging stations—73 DC Fast and 207 Level 2 charging stations—throughout the Chicago area.

The project is intended to help the City address two of the most vexing challenges facing widespread adoption of EVs: range anxiety and access to a garage for overnight charging. 350Green plans to install and operate its stations in partnership with retail hosts across high-traffic urban shopping centers and other places near where Chicago-area EV drivers live and work.

Chicago is on the cutting edge of national efforts to prepare for electric vehicles. When this project is completed, Chicago will have the most DC quick-charging stations of any city in the country, with only the entire State of California surpassing our station numbers.

—City of Chicago Mayor Richard M. Daley

The City of Chicago and its Department of the Environment are helping facilitate the implementation of the project. Much of the early focus around EV infrastructure has been on putting charging stations in the home garages of customers, which benefits only those who have a garage, the partners noted. Since many residents in Chicago do not have access to a garage, this effectively limits the number of people who can participate.

The project is valued at $8.8 million, with public funding of up to $1.9 million. 350Green will fund the remaining $6.9 million.



Is this the first DC charge stations in large enough quantities? It could be the quickest way to get a fast charge.

Computer switching power supply technology can make a light weight charger that can take in AC, DC or multiphase and adjust to the power available. It could even "borrow" the charge from another vehicle or stationary battery which can be cheap lead technology with the best computer controlled chargers and maintainers and desulphaters for a long life of many years. And it can be made into a power backup for the house and could even earn "spinning reserve" voltage support payments or some for power factor correction.

Some German locomotive builders still believe that you must have a low frequency transformer on modern lokomotiven that operate under the 15 kv 16 2/3 Hz catenary. A very high frequency converter can be built that could run under any catenary voltage and frequency or none for a few miles or on widely interrupted third rail systems. The third rail could even have AC on it.

I have decided to promote thinking about a SODIUM metal fuel cell for vehicles. You can invent how it works, but the beta-alumina solid electrolyte makes it possible. The ZEBRA and sodium sulphur batteries are actually fuel cells contained in a can.

Forty-eight Volt conductor ribbons could be glued to the floor for power pickup almost anywhere.


HG: Yes, e-energy can be produced, stored, transformed, transported and used many different ways. As such, it is definitely the clean energy/power of the foreseeable future. Thermal and mechanical energy/power sources and usages will be around for a while because we have been using those two for centuries and deniers will fight the transition as they would fight any changes.

1. Producing vast quantities of clean e-energy is not a challenge.

2. Clean e-energy storage is currently a challenge but it will be solved.

3. Using clean e-energy efficiently instead of wood, coal, oil, NG/LG, biomass etc is straight forward common sense and it will prevail.

Of course, people making a fortune with existing polluting energy production, transportation, distribution and uses will fight any changes that would reduce their business and profits. That's what the majority will have to face, combat an defeat.


By the way, we already use over 60 Kwh/day/household in our area. Another 7 or 8 Kwh/day for a BEV would not make that much difference.

A mid-size BEV consumption could be more than offset with the use of a high efficiency (SEER 20+) Heat pump and more efficient appliances in every house.

No additional e-energy is really required for one BEV or PHEV per household.
