Assuming a big pack of 100 kWh, it would now cost $5.6k instead of $12-13k at the beginning of last year. That's not nearly enough for the price changes you mention. Most battery packs are about half that.
Something like the BYD Seagull:
If a 50kWh battery costs $3k plus a few hundred for an electric motor, then EV's have reached parity in cost.
