There seem to be many competitors for that "first series-production electric" position, as for:
the "first electric truck".
Without even trying to figure out who really was first I do have a perspective.
First, one of the first cars I ever drove was a Baker owned by a friend and mentor when I was about 14 years of age. Among their large antique cr collection was that Baker, which was used as a daily driver. It had quite adequate range for local use in 1961, when I first saw and later drove it. The real problem for both Baker, Detroit and the earlier builders was that their cost was much higher than were the ICE. Even worse, most houses did not ahem electricity at all, so charging was a serious problem.
