Electric Bus Drives 1,100 Miles, on a Single Charge

Modern EVs like the Tesla has proven that range is pretty much no longer a concern for electric cars today. That may still be up for debate with heavier EVs however, as these types of all-electric roadsters still need to account for much bigger loads over the same urban distances.

Thankfully, it seems that heavy-duty EVs are already reaching the battery range technical threshold. Proterra Inc. has just showcased to the world how its bus can go over that long mile, several thousand times over.

A Catalyst E2 Max, one of the many electric buses deployed by Proterra Inc. has recently achieved a major milestone driving range of 1,100 miles (1,770 km). It was reported by the company last Tuesday, demonstrating the current bus model’s range capabilities. The bus drove for 18 hours at 60 mph (96 km/h), with a 660 kWh battery used for the entire run. The record was set at the Navistar Proving Grounds in New Carlisle, Indiana.

To be fair, this probably wasn’t directly a non-stop trip, and the bus was devoid of passengers. It was also reportedly driven at such cruising speed, so there are quite a few external assisting factors to this record-breaking achievement. Nevertheless, it was still all done on a single charge with a significantly larger form factor, which makes the milestone completely worth a piece of record for the books.

Additionally, a distance of 1,100 miles certainly isn’t something to just scoff at. Regular public buses tend to simply run a few hundred miles every single day, so the issue of charging delays with this kind of monstrous range is definitely non-existent. In other words, the largest issue that hinders the implementation of heavier EVs today might just have been single-handedly dispelled by this recent achievement.

And Still One Road to Progress

Proterra definitely has been on this development track for a long while already ever since it was founded in 2004. The aforementioned Catalyst E2 Max model alone was subjected to a number of tests and incremental improvements over the last couple of years, before the company was able to achieve its record-breaking driving range. This is why it is quite peculiar that the achievement was timely done at this current point, where larger electric vehicles are now being taken with considerable practical consideration.

No doubt, with the impressive record that was set by Proterra, the public would most likely be far more receptive to mainstream electric vehicles than ever. At the very least, this should further shake the authorities’ minds away from the antiquated laws and regulations that were in favor of dirty gas guzzlers for so long.

As for the previous record, the longest single charge distance achievement was held by Schluckspecht (literally means “Boozer”), a rather tiny experimental EV built at the Germany’s University of Applied Sciences. It achieved 1,000 miles (1,609 km) on a single charge last 2011, driving in successive bursts that totaled to about 36 hours and 12 minutes.
