Bollinger Motors final week offered somewhat extra element concerning the battery pack that can energy its lineup of rugged vehicles, encompassing the B1 SUV and B2 utility pickup, plus different business layouts.

Pack sizes for the Bollinger-developed design will vary from 35 kwh all the way in which to 175 kwh and past, with 70-, 104-, and 140-kwh variations in between. There’s additionally the potential for 350-volt or 700-volt configurations—probably permitting quicker charging, relying on nuances not but disclosed.

To match, the GMC Hummer EV launched final week can have an estimated vary of greater than 350 miles from a battery pack that sums to greater than 200 kwh and provides 800V charging. 

In a structure that’s fairly a bit completely different than different passenger-vehicle battery methods—extra of an elevated ‘T’ form—Bollinger’s pack makes use of a structural I-beam down the center of the pack, together with channels that route cooling fluid and funky particular person modules.
