Nitpick: the unit you mean is kWh, not kW, which is a different, though related, unit of merit for batteries. (kWh measures capacity; kW measures output.)

I think there's a bit of confusion about Pack prices vs Cell prices. The $145 is cell only, which is one of the reasons it is so much lower. There don't seem to be consistent pack-pack price comparisons.

I agree there is a disparity between the Bolt's cell-only cost vs Tesla's cost all-in on a pack. Regardless, the cost is below $200/kWh, and it appears that the cost decreases will continue.

GM says li-ion pack costs for its Bolt are ~$145/kWh, predicting $100/kWh by 2021: http://www.hybridcars.com/gm-ev-battery-cells-down-to-145kwh...
Tesla confirms its costs are below $190/kWh: https://forums.teslamotors.com/forum/forums/battery-cost-bel...
Batteries are following the same price curve of solar panels, and are about to get stupid cheap.
EDIT: If Tesla is able to drive down battery costs to below $100/kWh, I assure you, EVs won't be the biggest success story; you'll be able to turn every wind and solar generator into dispatchable generation cheaper than coal, nuclear, and natural gas. We'll be off fossil fuels in ~10-15 years.
