I've read about battery cost improvements around 18% per year. If you consider that the battery is somewhere between 30% and 50% of the cost of the car, they should be able to reduce the price of the car by thousands of dollar a year. Edit: This 2017 PDF illustrates this well. While the 18% looks accurate for 2010 thought 2016 they are projecting that rate slowing down. Page 8 has a good chart illustrating how EV cars will soon be cheaper then ICE cars. https://data.bloomberglp.com/bnef/sites/14/2017/07/BNEF-Lithium-ion-battery-costs-and-market.pdf https://data.bloomberglp.com/bnef/sites/14/2017/07/BNEF-Lith...
