The not too long ago unveiled GMC Hummer EV is an all-electric high-end pickup truck, however one factor appears to be a priority – the vary of as much as 350+ miles (563+ km) within the prime model.

The inexpensive variations will be capable to go just for 300+ miles (483+ km) and 250 miles (402 km):

  • Version 1 (Fall 2021): $112,595 (MSRP)
    vary of 350+ miles (563+ km)
  • 3X (Fall 2022): $99,995 (MSRP)
    vary of 300+ miles (483+ km)
  • 2X (Spring 2023): $89,995 (MSRP)
    vary of 300+ miles (483+ km)
  • 2 (2024): $79,995 (MSRP)
    vary of 250+ miles (402+ km)

The rationale behind the vary removed from 400-500 miles is fairly easy – a car of such measurement, with that form, weight and wheels, is just not very environment friendly.

Assuming 200 kWh (the pack capability was not introduced), 350 miles means 571 Wh/mi (355 Wh/km), even earlier than towing something.

In keeping with the Engineering Defined video (see beneath from about 14:25), the GMC Hummer EV shall be outfitted with over a 200 kWh battery pack (GM’s representatives reportedly hinted at it, however later advised us that the determine is just not confirmed).

The truck shall be outfitted with Ultium Cells batteries – 24 modules, 24 cells every (whole of 576 pouch cells).

Assuming Engineering Defined’s quantity {that a} single cell has a capability of 100 Ah, we are able to estimate the pack’s nominal capability just by assuming the nominal voltage of the cells:

  • at 3.5 V: 201.6 kWh
  • at 3.6 V: 207.4 kWh
  • at 3.7 V: 213.1 kWh
  • at 3.8 V: 218.9 kWh

We guess that one thing round 215 kWh with 200 kWh usable could be a good quantity.

One of the vital attention-grabbing issues about GM’s battery strategy is wi-fi communication between the modules.

The 800 V battery system is able to cost at as much as 350 kW of energy (from DC quick chargers). In about 10 minutes, some 100 miles (160 km) out of the entire 350 miles vary, might be replenished within the prime of the road model.

100 miles is 28.5% of the entire vary, whereas the ten minutes at 350 kW peak would translate into roughly 58 kWh. The 100% vary would then be 204 kWh (most likely much less, as we doubt the flexibility to stay to 350 kW for the whole 10 minutes).

Anyway, additionally this manner we finish with a conclusion that the pack is round 200 kWh usable.
