From a 1961 Ford Times:
We want to call your attention to the 1961 Thunderbird Junior, because juniors are as much in love with Thunderbirds as their elders are. This is an electric car that will run five mph for eight miles with one charging when operated on a paved surface. It will take two youngsters (under 5'-4") or one adult. To recharge the battery simply plug it in. Made by the Powercar Company, Mystic, Connecticut.
