Re: Tesla: Not so easily bricked

If there are 8k individual cells in the battery pack, what happens when an individual cell reaches zero? Will that individual cell be permanently dead, or can it be revived? You would think with 8k individual cells, if you left it unplugged for just a couple of weeks (instead of the 6 weeks needed to brick the entire battery pack), using a normal distribution you could expect that at least some of the cells would rea…

This is an exceptionally lame rebuttal. > There is a fundamental problem when any rechargeable battery is discharged and then left to sit for months. Any boat owner understands that that's why you plug in a trickle charger when the craft is put into storage. Yes, it's an excellent strategy to assume that your car buyers will also be boat owners, and therefore know all the things that boat owners know without you need…

I think the point there is that anyone purchasing an electric vehicle should do some basic research about electric cars and batteries. It's not that they should know this because boat owners know it; instead it's that they should take it upon themselves to find out this important and simple piece of maintenance, just as boat owner's have done. In other words, when you buy a boat, you understand that it's different from your (gas/diesel) car and you find out what you need to know. An electric vehicle is different, too, and you should act accordingly.

Earlier quoted context omitted.

The response from Tesla does not contradict that notion. Note this quote: "It's true that a full discharge to zero percent state of charge can potentially be damaging to a battery. " Notice that "can potentially be damaging" is a weasel phrase for "brick". Further Tesla argues that to avoid discharge to zero percent "all that needs to be done is to tow the vehicle to a charger". Again, this misses the main point of t…

My understanding of what this post meant is that a full discharge is prevented by the controller in the battery itself - much like in laptops, and much like everyone here was surprised that the Tesla battery does not have. So, to be clear, my understanding of this post, with full clarity, is: "A full discharge is disastrous. However, the situations reported were not full discharges. The controller in the battery shut…

Yeah, that is what I picked up from this post. But, I still don't understand how towing and recharging the batteries can cost $40k. Either the original claim about the cost involved in recharging is wrong, or this post claim that the fix is to recharge the batteries is wrong. There is a third highly unlikely case that Tesla is fleecing the customers, who in its mind, made the mistake of letting the charge fall down to zero.

For the sake of electric vehicles, we need to know which of the three scenarios is true.

Actually, it seems to me the article doesn't really contradict the accusation at all. There is a fundamental problem when any rechargeable battery is discharged and then left to sit for months. Any boat owner understands that that's why you plug in a trickle charger when the craft is put into storage. The line above indicates, on the contrary, that yes, if you don't drive it for a while and it wasn't plugged in to a…

You may be right - I don't have any outside sources that I know of (yes, okay, or care to) to corroborate either side.

I don't think it's reasonable to expect the consumer to do research of any sort. It would be very easy for Tesla to mention this at the time of purchase, document it, and also provide a dashboard notification of some sort.

I think the original article also made the same claim: Tesla is "not so easily bricked" (given the fact that 'only' 5 cases could be found). So this isn't a rebuttal. If it was to be a rebuttal, the claim would be "Tesla cannot be bricked" or something like that. This article did not do any background work. Why didn't he talk to the Tesla service manager(s) who were quoted in the original article? Even if he managed…

Considering the original article didn't actually cite sources, just made stated that a manager claimed this, a customer claimed that, it'd be pretty hard for him to talk to the service manager.

When you buy a Tesla the following happens:

* You are vebally told about this.

* You are then shown a document to sign that you were told about this

* Your car will beep loudly when its under 5% charge

* If its a newer Tesla it will beep and also log an issue with the service center, who will then continue to call you to tell you to plug it in.

No boat experience required.

Doesn't explain away the previous post - if repair is so trivial, why were 40k repair bills being discussed?

Maybe the $ 40k repair bills never existed in the first place...

It was never disputed by Tesla's PR + leaked emails point out the same number:

The rebuttal is in many cases a car will act like it's bricked, but can be returned to service without replacing the battery pack. I have had laptops do the same thing where after a deep charge I needed to go though a specific procedure before they where in full working order again. Honestly, 'reboot the battery management system' sounds like the same basic procedure.
