Roadster 3.0

[tvuolo]

wouldn't it be cool to have a 'modern' PEM - new tech components to do the job? probably a bit smaller some of them, more room for cooling? dreaming...

I'm pretty sure the Drive eO guys did that in 2014 for the Pikes Peak Hill Climb: Drive eO Returns to Pikes Peak with Bespoke Tesla Roadster – Drive eO. We really need to get the plans from these guys.

@Kerios made an approach, but I think it fell on deaf ears.

A heads up for 3.0 owners: It is fairly cold by UK standards at the moment, around 1 or 2 deg C. Yesterday I charged up to 67%, switching off at 8 AM and putting the car into storage mode. By 8 PM the SoC had dropped to 58%.

Yesterday I did my first drive with the 3.0 where I had to dip into the lower end of range mode. Everything was fine on the drive home and I got back with 35 miles ideal / 21 estimated. The VDS battery had gone red but there were no warning messages. I didn't get the "cannot calculate range" warning.

I plugged in but immediately got a warning that the pack voltage was low and the car was doing a recovery charge. It had gone to standard mode charging and the range was showing 0. It only started charging normally again above 40 miles estimated.

The only time I had a recovery charge before was on arriving in Edinburgh 7 years ago, when I was driving 14 miles in cannot calculate range mode after the counter passed 20 miles. That was not surprising, but if I am going to get recovery charges at 40 miles then to me that means the 3.0 range is 40 miles less than claimed. I think @Kerios had exactly the same experience.

I also guess that you need to get a step-down transformer or ship it over here; I'd look after your shiny new battery.

Weird. I have been down to zero three times since I bought my car in 2011 and never received such a message. The third time was after the new battery was installed. Everything was fine after I recharged so I don't think there was any damage done.

@dpeilow, now that you've cycled the battery completely, it would be great to get an updated CAC over to @bolosky for his 3.0 longevity graph. I wonder if there has been a step change in value for yours (hopefully up)?

Unfortunately the 3.0 battery behaves differently than the old battery. So it will act differently than your current battery.

Some quirks are the last 3% of charge takes a LONG time, like 2 hours long.
The battery charges to a lower state, in standard mode 79% versus 84%.
So the difference now between standard and range charge is 120 miles versus the old 50 miles.

I have pulled the logs and intended to send them over after this drive anyway, but strangely the CAC has remained at 212.57 for weeks now.

EDIT:

Here are the sections of the log file showing that I got down to 11% real SOC. Showing 35 miles left at that point is not clever IMHO.

My car was parked for 3 days in the garage and with the recent sub zero temperatures we have been having, the battery was down to 0°C.

I wanted to charge last night so I switched the plug on and expected to go to bed. It started pre-heating the battery, as I have seen before, but this time it was much longer before it actually started charging. The battery was up to 16°C before I gave up watching and went to sleep, but I can see from OVMS that it was 1h45m before it actually went into charging mode. This seems much higher than I remember - is it a 3.0 thing?

Hi David. As I just txted u, I had 0% unknown range, and did a charge one day after the London snow melted. I have 2.5 battery.

It took 1hr to warm up. So I think 1h45min for a bigger 3.0, in the previous day full on snow cold, seems reasonable?

Well it isn't materially any bigger or much heavier, so that shouldn't really matter. Did you happen to notice the temperature of the battery when it went back to normal charging?

Does anyone know the costs for the 3.0 upgrade?
I remember in USA it used to be $ 29.000 which is now approximately € 25.000
I got a quote today from Tesla NL of € 35.200 excluding installement
Is it this expensive in all countries in Europe?
If UK is £ 26.000 I can better get installement done in UK
Or Germany? What are prices there?

From tesla shopping page

Roadster 3.0 Battery Upgrade
$5,000.00

5k is deposit on 29k total

 

[Marius]

This means I save 15000 USD minus shipping if I ship my Roadster to USA.
I have seen different prices per country in Europe probably depending on importtax and VAT so I am interested to learn if ordering from another country like UK of Germany brings me a cheaper pack.
Price in NL is 15000 USD higher than price in USA.

 

[snd92]

Try Norway @Marius. Zero tax on batteries for electric cars

 

[Marius]

Snd92, Are you able to ask servicecenter Oslo a quote?
If it is seriously cheaper I consider to drive to Norway, have 5 days holiday in Oslo and return with a new pack
It would be great if you can get this info.

 

[snd92]

Send an inquiry to [email protected] (SC at Bærum/Rud, just 20 km from Oslo) with your VIN. Usually, they'll answer you within a day or two.

 

[Marius]

Thanks, i will do that

3.0 waiting time to Hong Kong is now 9-12 months, wish me luck !
