How automakers can drive electrified vehicle sales and profitability
I had no idea lithium ion batteries had become so inexpensive.  Here is the top search for "kwh battery" on eBay right now:<p><a href="http://www.ebay.com/itm/Li-ion-Lithium-24vdc-100ah-2-4kwh-NEW-2015-VOLT-Battery-Off-Grid-Solar-Battery-/182436435488" rel="nofollow">http://www.ebay.com/itm/Li-ion-Lithium-24vdc-100ah-2-4kwh-NE...</a><p>So with shipping, $869.96 for 2.4 kwh, or about $362/kwh.  A $3 gallon of gasoline has 33 kwh, but only 8 kwh of usable energy due to the inefficiency of internal combustion engines, so $0.375/kwh.<p>So batteries are somewhere around 1000 times more expensive than gasoline, but, if they can be recharged more than 1000 times they may actually be cheaper.  1 kwh of electricity costs about 10-20 cents usually (call it $200 per 1000 charges).  That's a total of $1069.96 for 1000 cycles, maybe $1269.96 for 2000 cycles, etc, something on that order anyway.<p>So $1 per cycle per kwh is pretty close to a breakeven against gasoline, and batteries are only going to get less expensive.
