DETROIT — General Motors on Thursday said that it would upgrade the steel structure and liquid cooling system that surround the battery in its Chevrolet Volt to address concerns that the car could catch fire after a severe crash.

Company officials said they had shared their plans with the federal safety regulators who had been investigating the fire risks of the Volt, an electricity and gas-powered hybrid, since November and were “optimistic” the action would satisfy the government’s concerns.

The National Highway Traffic Safety Administration, in a statement posted on its Web site, said the changes “should address the issue,” though its investigation remained open.
