Re: b b bb BOLT (yes BOLT) to take on Model 3

^....that $9,000 comes from an 'unnamed source', just like it did for the Volt, and they were wrong then. Their error was trying to amortize the cost of battery technology on one vehicle and one generation of that vehicle. Kinda like trying to tie all the developmental expenses of a new gasoline engine to one vehicle and one generation of that vehicle. I remember that GM had to set them straight and explain how the auto industry works. This is petroleum friendly group trying to create negative press for EVs that are increasingly displacing combustion engine vehicles.

^ well Bloggin, NOT that I put that much credence in Bloomberg anymore BUT
posted them as the origin of an FB link I saw from
AutolineDaily

who^which
doesn't offer any evidence for THEIR comment that at least GM's $9k is
less than "the 14 Thousand Dollars that Fiat loses on every 500e"


fwiw

Thatís not 2:15AM tomorrow, the Bolt wonít be charged until Tuesday morning, assuming I donít drive it. I get asked frequently whether or not you should buy a home charging station for your electric car, the answer is yes unless you really can handle extremely long charging sessions.

Yep...must be plugged into a 110 outlet that offers 3-4 miles per hour of charge. A 220volt at about 25 miles per hour is mandatory for home charging with the 200+ mile EVs.

One of the drawbacks to fast charging, is battery life degradation. The faster it charges, the more stress on the battery and the shorter the life span.

That was more of an issue with the early first gen battery packs, especially with Leaf that has no thermal protection. But today, the new packs can handle up to 300 Quick Charger cycles before the vehicle will slow the charge rate when the battery is cold, and when the pack is just about full. This is all to increase the life of the battery pack for the long them, whether it's DC charging or Level 2 at home. However, it's very rare for someone to have such a high DC charger rate for a few reasons.

Not much has changed, actually. At least according to the site below, which seems to know batteries quite well.

So if you travel with your EV, it is not suggested to fast charge too much. That is quite a hassle.

It looks like their focus is more about Ultra-Fast Charging, that's primarily used on commercial trains, and the new city buses, etc. For consumer vehicles, Fast Charging or DC charging of at least 300 charge cycles is a threshold before the power is throttled back a bit to preserve the longevity of the battery pack and range. Which would be about 6 years of ALL DC fast charging before an adjustment would be needed.

Which would indicate that the twice-yearly road trip with the EV, and if there is a need to use a DC fast charger, the owner would have over 100 theoretical years of DC fast charging before the software regulates the charge speed....still without any range degradation due to using the DC fast charger.

I would expect it would be the new upcoming long distance EV tractor trailers that may need consistent DC charging that should have this issue resolved before launch. But the short run delivery eVans Ford is working(and DHL is building now) on in China should not have to worry about too much DC charging since the routes should be within the range of the initial charge, since the daily urban routes for UPS/Fex-EX range from 50-70 miles with lots of stops between with a 100+ mile battery pack.

Still, the point is, the faster the charge rate, the more stress and degradation to the battery. Especially in the cold.
