(a) Excerpt in the window of print: The storm ravaged some electric cars, but the batteries endured.

(b) Quote:

Nissan’s decision to encase the Leaf’s battery in steel may help explain why federal safety regulators investigating postcrash fire risks in the Chevrolet Volt do not have the same concerns about the Leaf. General Motors packages the Volt’s battery cells on a T-shaped steel tray with a plastic cover.

"the Ford Motor Company is following Nissan in putting a steel case around the pair of batteries that power an electric version of its Focus compact car, which it started building this month. The [Ford] decision about the battery casing was made long before the Volt’s problems were known.

"Tesla says it encloses each battery pack’s 6,831 cells in steel to protect them and dissipate heat.
