Correction
On a pair of hyphens dropped from Vehicle-to-Home.
An earlier version of our report on Hyundai Motor Group's AllDayEnergy rendered one of its services as "Vehicle to Home," the hyphens dropped. Hyundai hyphenates it: Vehicle-to-Home. Without them the phrase is three nouns standing near one another; with them it is a direction the current travels. The record is corrected.
