Solar powered electric car charging station opens in Chicago

The Chicago area’s first solar powered charging station is unveiled, supporting charging two cars at a time while protecting the electrical grid from demand spikes.

Chicagoland’s first solar powered electric car charging station has been completed according to an announcement today from AllCell Technologies and Windfree. The charging station installation is completely powered from an overhead solar canopy, and includes two charging stations.

Development of the project was managed by Windfree, of Evanston IL. The installation includes a 10 kilowatt solar canopy, 40 kilowatt-hour battery system, and two Level II charging stations. The 40 kilowatt-hour grid energy storage battery system directs energy from the solar panels into the battery pack. The system ensures that when a car is is charged the energy comes from the battery pack, rather than directly from the electrical grid.

The battery pack acts as a buffer between the charging station and the grid, ensuring that the electrical grid doesn’t see a demand spike as soon as a car is plugged in to charge.

One of the charging stations is used exclusively by car sharing firm I-GO, while the other is available to the public.

Alternative Transportation for Chicagoland owns the installation, and other project partners included architects Farr Associates and Continental Electric Construction Company.
