Ecotality, which makes charging systems for electric vehicles, says it has filed for Chapter 11 bankruptcy protection.
Ecotality Inc. said it made the filing Monday in Arizona. The company had said in August that it might be forced into a sale or bankruptcy filing after disappointing sales and a suspension of payments from the federal government.
The San Francisco company makes charging and power-storage systems for electric vehicles under the Blink and Minit Charger brands, including charging stations for the Nissan Leaf. It also does testing for government agencies, auto makers and utilities.
Ecotality has received more than $100 million in funding from the Department of Energy.
