Delayed charge times after software update?

Our Model S update happened a couple days ago. I've been wanting to set the charge time but didn't see that in this update. Am I missing it or did that feature not make it into the latest update?

Our electric rate is $0.03 after midnight, so I'm motivated to take advantage of the cheaper juice but don't want to stay up late to plug in the charger!

In the meantime, install a switch in your bedroom? >;)

Simpler still - plug-in timer.

How about:

Plug it in when going to bed with the charging rate set as low as possible and still be charged and ready by morning. That way most of the charging can happen after midnight. Still not as good as setting a start time, I know.

Great (funny) suggestions. I'm just so used to my Roaster coming on at 2am to charge, it seems weird that this isn't supported in the Model S.

A 220v timer switch seems a little scary. Maybe I'll try lowering the amps, that might be better on the batteries too...

The timer switch is actually a good idea, except that I couldn't find any 240v plug-in timers online that also support 40+ amps. at least, not for under $600 or so.

If I didn't think this issue would be resolved in another software update soon, I'd think about soldering up a timer socket myself. I'm sure the parts could be had for < $100.

I was going to just leave the breaker off, hook up the charging cable when I get home, then turn the breaker on near midnight.

However, the charging port detects the connector in proximity and pops open, but will it do that if the charger isn't powered? Can the charging port be opened manually?

This thread makes me wonder:

How many people do they have working on software updates? And what is their priority list? Because I would have thought adding charge scheduling would be way ahead of adding "creep". The former is something most owners will want, while the latter seems completely stupid for an electric car.

@tesla.mrspaghet, I agree that the need for delayed charging is important, but when you are filling a Model S battery from nothing to 300 miles at the cost of about $12 in electricity, it's not a HUGE deal IMHO.

Now "creep" is a MUST for anyone who drives in heavy traffic ALL THE TIME. Life would just suck without it. I have to humbly disagree with you on this point.

Besides, it's easier to add new code than it is to debug code that isn't quite doing what it should.

@BYT: Really? Have you driven the Model S a lot in heavy traffic?

I have no experience other than with a standard ICE vehicle, but I'm thinking it would be a difference between operating the brake pedal most of the time (ICE), or operating the accelerator most of the time (Model S).

It seems like it should be almost the opposite between the two: for an ICE, you lift up on the brake to crawl along and step on it again to stop. With the S, you step on the gas accelerator a little bit to creep and lift up on it to stop.

Am I wrong? What's the advantage of "creep"?

Creep can allow both feet off the pedals, a definite bonus for those who like that.

@sbern:

With regen braking, you can also have both feet off the pedals when stopped, no? So again, it's the difference between having your feet off the pedals while moving or off the pedals when sitting still.

I still don't see it.

I still don't see it.

Creep is most helpful on a slight incline when using a single foot to operate the pedals. After you come to a complete stop on slight incline (by depressing the the brake pedal), you can let go of the brake and the car will start to move forward. With no creep, the car moves backwards. The Model S will have both creep and hill hold software installed in the future which will make it able to stop without rolling backwards on more inclined hills. Hopefully, each feature can be turned on/off separately.

@@tesla.mrspaghet., When I am at a stop sign (also a lot of those in my travels) and there is a 2 block line of cars, I don't hit the accelerator or the brake. I let the car creep the WHOLE 2 blocks. No foot on either pedal. Sometimes when traffic is consistent on the highway, I use creep the same way.

@BYT: Ok, I guess I don't have the relevant experience in heavy traffic to see the value. I pity you :)

@tesla.mrspaghet, One of the many MANY reasons I am buying a Model S, to make my drive more tolerable... :)

I have been in Florida traffic once on the highway gulf side and was in traffic like BYT describes... really sucked.... for a few miles. I cut over to a toll road which was empty. (too lazy to go to google and look them up.)

@Sudre_: Nice. I restricted my search to plug-in timers.

I guess you'd install this one between your panel and the 14-50 outlet?

If you have the plug installed it would be so easy.

There are several ways to do it. The easiest.
Buy that timer.
Buy a heavy duty 14-50 extension cord.

Buy two cord grips. (simple wire connectors are cheaper at Home Depot)
http://www.grainger.com/Grainger/HUBBELL-WIRING-DEVICEKELLEMS-Strain-Rel...

Cut the extension cord in half (probably better to just use 3' ends)
Wire them into the timer thru the cord grips.
Hang the timer on the wall next to your plug.

It's not a cheap creation. Would you get a return worth the investment?

The other thing I was thinking about actually making, maybe selling, is a loss of power audible alarm for those RV breaker trip moments. When the breaker trips a loud alarm would sound for 5 minutes or so.

I just keep thinking Tesla will get the software done sooner than later and there will be no need for any of this stuff.

Agreed, I suspect they'll have scheduled charging, the smartphone app and a bunch of other stuff by the time I get my car. I guess that's one way to console myself for not being an extremely early adopter :)

If you spend $600 on an timer that can handle the juice running through it, divided by the cost difference in electricity savings and assuming you charge every night. Let's say it saves you $5, that will take 120 days for you to recoup that amount. If Tesla Motor's incorporates the software update within 4 months, well, you can see how it would be a waste to bother. That doesn't include the costs for Sudre's solution, tax and shipping on top of that.

Creep is great for traffic. I can creep up a hill in traffic with a g37. In an S you would roll back. If it had hill hold, but no creep then you wouldn't roll forward in traffic unless you were going downhill. You'd just let go of the accelerator and the car wouldn't move. I'd much rather trust the break and creep in traffic then the accelerator and no accelerator with roll.

Most buyers are used to creep, but scheduled charging not so much. Have to bridge the gap before you can innovate IMO

I guess another reason the value of creep was not immediately obvious to me is that I'm used to driving in Houston where there are no hills.

But are you sure the S would roll backwards on a hill? I would think regen would tend to keep it in place unless it's a pretty steep grade, but will take the word of those who've spent some time behind the wheel of the S on hilly terrain.

regen only works going forward not backwards. i was on a slight incline and almost hit the car behind me

@tesla.mrspaghet

You don't have heavy traffic driving experience in Houston? Man where do you live. I do Woodlands to downtown everyday for work...I use the LEAF creep and (not very aggressive) regen for the slow and go traffic.

I always had stick shifts before, it was only the clutch pedal that go old in traffic. I personally think the Tesla setup, all regen on the Go pedal, with no creep would be my ideal setup. At least Tesla will give the choice on creep.

Tesla.mrpaghet:
Yes! It does indeed roll backwards on the slightest of inclines. It drives me nuts. They really have to fix this.
I got the car last week and other the cruise control being were the turn signal should be this is my other majot complaint. It rolls backwards!

I have been having a hell of a time with motions sickness while driving, yes driving, and I think part of my problem may be the backwards creep. Have you ever had that weird, head-spinning experience when a car next to you rolls backwards and you, disoriented, think that you are rolling forward. So you push the brake harder... And harder.. And nothing... Then you realize it is the next to you going backward.... And u get dizzy. It's crazy

BUT, I still LOVE my model S and I love Telsa. It's an amazing car and Tesla really cares and they will get it right.

@kalikgod: I do the opposite commute from you - I live in the Heights and work in the Woodlands, so going against traffic both ways :)

So you do that commute in a Leaf? I'd think that would be really pushing the range, unless you drive 50 mph or something. The round trip for me is about 65 miles, and that's if I don't have to pick up my son or make any detours. I wasn't about to buy an EV unless it had beaucoup range and never expected to have that option before like 2018. One of the reasons I'm so excited about the Model S.

@skystream & Tomas:

Ok, thanks for the education. I guess I'll have to experiment with the creep/regen settings to figure out what works best for me. But at worst it sounds like no more hassle than a stick (which I drive now). I'm sure I'll get used to it.

Yeah, my wife rolled backwards her first time behind the wheel and thought the car was in reverse. This is why it needs creep ;)
