Tesla Inc.’s rollout of its all-electric Semi in mid-November 2017 was the easily the most celebrated electric truck unveiling ever, but it was hardly the first.

Large-scale electric trucks, although unusual, have existed for many years. They’ve served as mail delivery vehicles, garbage trucks, and, more recently, over-the-road freight-haulers. In all cases, they’ve slashed carbon emissions to zero while eliminating the baritone rumblings of the conventional 18-wheeler.

To be sure, many of the electric heavy-duty trucks on the market today haven’t advanced much beyond the prototype stage, but hopes are nevertheless high for them.

Following are some of the most notable trucks to be powered by batteries. From the 3.5-HP electric delivery vehicles of the early 1900s to the 1,000-HP models of today, here’s a peek at some of the auto industry’s most impressive electric production trucks and prototypes.
