You scan do it from the phone app or through the touch screen. Tap the lighting bolt icon near the top and then set charge limit. Use slider or arrow buttons to change.By the way, how do I set my car to charge to 70%?
Sorry I had no experience with the roadster. I was referring to the model S cira 2017Thanks @Snowstorm.
Ah, I hate to show more ignorance, but ... there's a phone app for the Roadster??
According to Tom Saxton 32 amps is the sweet spot. Faster or slower we have higher losses. And 32 amps is better for the utility as it is a more stable power flow. Then as an engineer virtually everything lasts longer under light use.I'm more interested in how FAST to charge my 2010 Roadster.
I've seen all kinds of comments, but I'm still unsure if it's better to charge slowly or quickly (i.e., lower or higher amperage).
Are there expert opinions on charging rate?
Thanks @dhrivnak. There seems to be a general acceptance of 32A as the way to go.
I decided to do a video on this as it's a fairly common question I've come across and hard not to get several different answers. So, I reached out to Jeff Dahn (Tesla Industrial Research Chair and Professor of Physics and Atmospheric Science at the University of Dalhousie in Nova Scotia). I advised I was planning to keep my X for approximately 2 decades and asked him where he'd charge the battery to for day-to-day use, with long term preservation in mind.
Check it out here:
For those that don't wish to watch the video he recommends daily charging to 70 percent and to go ahead and charge to 100 percent for longer trips. He also comments on Vancouver being a nice climate for lithium ion batteries. Cheers.
Hi @bcalfee,We have just bought a house (try to settle down?!) in Blacksburg VA. I asked electrician to install a Tesla Charger he suggested that the wiring difference between 40Amp (available) and 80A is around $150. I wasn't going to spend the extra as overnight charging would be the same.....
Does anyone know if it is better to charge more slowly? If I had the faster charger, I could keep the charge limit lower and have the option to top it off quickly. Any thoughts?
3) Deep discharges should be avoided.
Don’t go below 20% everyday. Seriously though, use your battery as you have to. Yes, full charge and deep discharge is bad, but it is more like eatting a Big Mac for your health, not an issue unless it is all you eat everyday.What is a "deep discharge"? The depth of the discharge or how far down you went? i.e; dropping 50% worse than dropping to a low % voltage remaining?
