Coda Holdings, the U.S. assembler of Chinese-made electric vehicles, filed for Chapter 11 bankruptcy protection after selling just 100 of its all-electric sedans, another example of battery-powered vehicles’ failure to break into the mass market.

The filing with U.S. Bankruptcy Court in Delaware will allow the Los Angeles company to exit the auto sector and refocus on energy storage, a far less capital-intensive business. The company uses the same technology it used in cars to build systems for utilities and building operators to store power.
