What is left out is the math of battery replacement.
100,000 miles and you must spend $10,000 for a new pack?
So 10 cents per mile. If you are selling your used electric car with original battery, with 30,000 miles on it; you have to deduct $3,000 from the price.
In other words, at 100,000 miles your electric car is worthless. While my Honda Civic is still worth $8,000 or so.
This was a common myth promulgated by certain segments of the media. Here are the facts: Chevy Volt owners who have been driving the car since the first Volt hit the market have driven 60,000 to 100,000 miles and have seen virtually no reduction in their battery capacity. Most people find this hard to believe considering their experience with their smartphone or laptop. However, the Volt uses a different chemistry (not all lithium ion is created equal) and more importantly, the battery is pampered: it has a controlled state of charge window and a liquid-cooled thermal management system. GM has test mule Volts with 200,000 miles on them and the batteries are still going strong.
