    Key Toyota executives explain Toyota's current approach to plug-in technology and describe current costs to be $10k for 20 miles of electric only capability. No time table is offered. They are not sure of the demand if they were to build it - but imply a typical purchaser would want to pay no more than $3k for the plug-in capablity.

    $10k for 20 miles extra EV-range is total BS and misdirection.

    20 miles range requires about 4-5 kWh, so they're quoting $2,500 per kWh for lithium-ion when the mass-produced LiCo 18650 cells are being made for wholesale costs of about $300 per kWh. Even low-volume Valence lithium-ion is less than $1,000 per kWh.

    interesting article and i fail to understand why they have not released the $10000 option. i would GLADLY do it. heck i paid $14,000 for an EV because i simply got tired of waiting.

    If you use 5kWh figure (a fair number at 70 mph) , that's $2,000 per kWh. The pack will probably not be discharged from 100% to 0% to extend the life and the consistency sake of the power output. If we assume 70% usable energy from the pack, that's $1,400 per kWh. If the usable energy is 60%, that's $1,200 per kWh.

    What is the life cycle for the cells you quoted? If they don't meet 10 years / 150,000 miles, you'll have to oversize the pack (increase the pack size and discharge less) too.
