Market Research

Houston to promote electric vehicleNissan has made agreements with cities and states to build public charging stations. •Cities: Houston, San Diego, Seattle and Orlando•States: Tennessee and Oregon•Houston has approximately 4.5 million vehicles with 86 million miles per day (state statistics)

In November, Nissan LEAF and Chevy Volt will be introduced. Both vehicles utilize battery power.¼ carbon emission linked with cars in U.S. and president Obama wants to put 1 million electric vehicles on the road by 2015 to reduce carbon dioxide emission.

Construction of charging station will be a major issue. One study by UC Berkeley indicate $320 billion in coming decade for construction of charging stations.

Electric vehicle charging stations for San FranciscoSan Francisco installed electric charging stations. The plug-in charging stations currently are aimed for electric vehicles in San Francisco’s municipal fleet and plug-in hybrids available in the city. This is a result from agreements between mayors of San Francisco, Oakland and San Jose.

San Francisco gears up for age of electric carSan Francisco adopted a new building code with a requirement of an electric vehicle charger for new homes and offices.

One in five vehicles sold in the Berkeley area are Toyota Prius, electric-hybrid vehicle.

San Jose has started reserving parking spaces for electric vehicles and installation of electric charging stations by major employers.

GE and Juice Technologies co-developing electric vehicle charging deviceBoth companies announced a joint development agreement to create intelligent plug-in electric vehicle charging devices. Device will be developed to help consumers to charge vehicles during low-demand, lower cost time period. Initial charger will be available during the second quarter of 2010 in U.S., with full scale production to follow.
