SF90 Charging

I don’t own an SF90 but I’d say with near certainty that you should only charge it to capacity and then unplug. I have an e-tron electric car as one of my cars and like any electric car or hybrid, charge it when needed and that’s it. Leaving it plugged in will do nothing as far as charge. The regular accessory battery can and should be left on tender though.

There is no regular battery tender on the sf90 like other Ferraris. I leave mine plugged in all the time

 

Oh interesting- I didn’t know. So maybe my response was full of sh*t and I guess the electric plug in also acts as a tender

I was instructed by the dealership to always keep my SF90 on the charger. So I do. I have taken it on a few weekend trips and the car did fine off the charger for a couple of days, but it stays plugged in otherwise.

Of course, I always keep all my Ferraris on the tender/charger whenever possible as 1. The 12 volt batteries are terrible. 2. The cars seem to be exquisitely sensitive to low battery voltage.

 

In my opinion, having a booster in the car is a must with Ferraris. I always keep mine on tender but have had some bad experiences a couple of times with the battery. I bought a NOCO GB50 and it gives me total piece of mind that I will be able to start my car even when nobody is around to give me a jump start. The thing is small and charges off a USB cable so very convenient to use and carry around, especially if you get the dedicated case for it.

Newbie to the SF90

My question is regarding the charging. There are 2 Led lights

when charging they both blink blue
When do you when the car is fully charged

it is blinking now with LED 1 only

 

I just cant picture a Ferrari that you have to plug in. Sign of the times I suppose....

thank you.... how do you hang your charger... the cord from the charger to the plug is so short. I have the charger sitting on a box so it does NOT hang from the plug. then when not in use. where to you place the charging port... any photos of how you store your port and the charger ???

 

See my reply in your other thread.

 

How long does it take to go from one green bar (close to empty) to eight green bars (fully charged), using a normal US home outlet?

 

thank you and I did purchase the hanging kit from amazon and it works perfect - THANK YOU !!!

 

one other very important thing not mentioned above is the order of the pluggings. you ALWAYS plug into the WALL FIRST, and the CAR SECOND. do not plug into the car first and then the wall. also, do not use an extension cord - even one rated for 15-20 amps or more (fire hazard; they get really hot).

fwiw i leave mine plugged in all the time.

created the above, printed and above the charging station.... LOL, and I keep my car charged all the time as well. Even if I roll in and there is 15 green showing on the dashboard

 

I got the SF90 today, I'm using the Superfast charging from the other supplier, not Ferrari one, it actually charge very fast, about more than 1 hours to FUll charge from Empty, 3,5kw charger

 

Also in the menu system make sure the long term parking is disabled if plugged in continuously

This seems counterintuitive - wouldn't you want long term parking enabled if plugged in continuously? I always assumed that setting lowered the max state of charge while constantly plugged in to avoid premature battery aging. Do you have some more info?

 

That’s exactly what the service dept at my dealer advised as well to leave the long term parking “on” and I did it initially but after a few days to a few weeks the app sent a notification about battery warning that long term parking enabled and battery starts draining despite being plugged in.

Disabled the long term in the menu and now the entire winter plugged in no warning and the app shows battery to full capacity in the green zone. I’m assuming the long term is meant when you park and do not have access to the charger.

So far I’ve done this with both my 296s and no issues.

Do you have link for the charger you are using, I would like to pick one up for my SF90 as well

 

I put 2K miles in 11 months on my 296 without ever taking the charger out of the bag. I am currently driving my SF90 the exact same way. The charger hasn't seen the light of day.

 

any public charger will work.. it the same port as other car
