Batteries

My son asked his contractor to arrange for 14-50 outlet. Instead of a surface mount, he installed a standard, plastic 4" box, and none too well -- it wiggles a bit. We installed the outlet, but the 4" galvanized 14-50 box does not fill the 4-1/2" hole the contractor cut in the sheetrock. Is...

I have never had to use any of the "Destination Chargers" that are on the Tesla map. However, I am taking a trip in a week where I may need to use one. Do these chargers have the appropriate Tesla plug, or do I need my UMC, or adapters. Thanks, Dave

I have a quite new S 75 and the full charge mileage gets lower and lower. I remember it being 220 then last week it was 219 now this morning it was 218. These are the values that Tesla App notifies after the charge is done not when I check the car. Is this normal or is my battery defective?

Hey Everyone, In trying to keep my thoughts and your read organized, I broke it down into sections. Thanks for your help! BEFORE I got my brand new Model X 100D in early September. Except for minor trim issues that I decided to leave be, it was the car my wife and I dreamed of. Over the last...

Hi folks, A friend of mine sent me this picture recently... He's got 85D model, about 3 years old. The trip included 3 rides, about 2 hours delay between each of them. Ambient temperature 5 deg C. There was 1% SOC left. The counter shows 66kWh consumed (and 1% left in the pack). It seems to me...

Hey folks. I am having an online discussion with a gentleman re supercharging. I have read the wikipedia entry on supercharging but am curious on voltage and currents. We were both technicians by trade in the miltary so understand the physics so this is more of a specs question. So, i know...

ok, i'm a pretty new owner so i didn't really know but i left my MX at my work parking structure last week and left town for a week. i didn't leave it plugged in...just wasn't thinking or knew i should do that. i also didn't put the car into low energy mode or anything like that. i did that...

I plugged in at a supercharger for the first time today in Sarasota, FL. It was a cool experience, although it was practically a ghost town (a lot of the surrounding stores are still under construction).

Does anyone know what this warning triangle on the usage graph means?

Seems like the energy density per unit weight in the roadster is higher than what will be in the Model 3 or for that matter what is in the 100D? Anyone know any of specs?

When we ordered our S 100D, 72A charging was an option. 48A was optional, and upgrading to 72A charging was $1500 as part of the original configuration and $1900 to enable after delivery. For 100D's, 72A charger is now standard. Based on how our garage is configured, with two Tesla Model S...

I've been waiting on Tesla to restock the cable organizer so I just plug in the nema 14-50 when I need to charge but then store the UMC in the round mesh bag when I'm done. Is there a reason why this practice is bad and I should just plug in all the time? Thanks

For the last few months, my battery mileage indicator has been overstating mileage by about 20-25%. So, it also drains faster than you’d expect. I have a 90D and my max capacity shows as around 350 miles instead of 290 and it drains 50 miles on average when I’ve only actually driven 40. I...

I am aware that certain batteries can be software unlocked for greater range. My battery is a 90 kWh so that does not apply to me. Assuming new battery production from the gigafactory continues to ramp up, I am hopeful current owners will be able to upgrade their batteries. I have an...

I'm guessing the New Roadster prototypes wern't possible until the Gigafactory's new 2170 cells were in production (for reasons of energy density and perhaps heat tolerance). So how are they pulling off 200kWh? Here are a few ideas: (1) Switching to air cooling? By pulling out the liquid...

Who does remember this discussion? Half a year ago or a bit longer Elon stated after answers: "it simply doesn't fit". Meaning the footprint of the M3 hadn't enough room for 100kWh. And that some people had questions about that statement. By then...how is it possible that the new Tesla Roadster...

For a mere quarter of a million you can, in 2020, have a 200 kWh battery pack - in the new Roadster. For about a year I've been saying we won't see 2170's in the S/X until late 2018 or even 2019. I know you are waiting with bated breath ;) but here's my prediction. Tesla will offer a 200 kWh...

Hi All! As all of us here are aware, I think the reveal of the new design was impressive along with the range and 0-60 times. What I think we can all have a go at on this forum is to work out the technical specs of the Semi-Truck as I think these will no be disclosed for a while, it will help...

It appears along with the Tesla semi event, HRSMotors went live which is a business owned by @wk057 and a partner offer a large range of tesla upgrades and Tesla electric components and drive units for non tesla uses, very cool! HSR Motors

...I'm going to ask it anyway. Since charge time is such a big deal with electric cars, is it possible to split a battery pack into 2 or more packs with each pack taking a charge from a separate Supercharger? And most importantly, would that speed up the charge time? It seems like it...

Hi All, My name is Shawn, I live in Southwest Michigan. My car is a 2010 Fusion Red Roaster Sport #785 delivered December 2009. I replaced the VMS and ESS in 2015. The car was plugged in to a mobile connector 14-50 240 volts with good voltage and no breaker tripped. Across the winter I...

Everyone knows charge rate drops at superchargers as the battery takes on higher state of charge, right? Well, I noticed that I have a pretty consistent cross-over point of 58. This is the number where charge rate equals state of charge. So I see 58 kW charging at 58% charge. This also...

Hello everyone. I live about 40 miles from work, and until recently, I could charge at work free for the day. I live in Southern California and the chargers seem like the type that are common and that Tesla provides the adapters for when purchased. They charge at an average rate of 22 miles...

At the WaWa at Sand Lake Road and International Drive

Just looking at the work order they sent me. Among other things they replaced the 12V battery with a "new nanocarbon 12v". I'm not familiar with this type of battery but hopefully they last longer than the previous 12v batteries. If anyone knows more about this type of battery I'd love to...

I have been looking through the forum for weeks, so much great info. I finally ordered Model X 75D about two weeks ago. Got the VIN now waiting for delivery(late December). Currently my main concern is charging the car. I am renting the house, the electrical panel is on the back of the house...

Probably a stupid question. I bough an unopened HWPC from a service center last week that has the attached label on it (says WC, NA, 1P, 208-277V, 80A, HW, LNG among other things). Is there any way to tell if this is the 25ft one or 8ft one without opening the box? Reason is that I wanted a...

Now I love my Tesla like a third child, but I have one niggle which worries me. Just what does the warranty on the battery cover? Just total failure or degregation over a certain percentage? For example if the car is 7.5 years old and I only get 100 miles from a charge, will they...

Just saw this on supercharge.info apparently work has started on the Queensway near the 427. It says it started 3 days ago. I'm going to check this out tonight on my way how. It also says that it's 10 stalls.

I’m an M3 res holder. The other day, following a major power outage in our state, my neighbor, an engineer, told me that when I get the Tesla, it can "power the house" during outages. Is this true? Is a Tesla a PowerWall on wheels? I’m sure it’s not that simple. Has anyone used an EV to power...

I have a question for those of you with Powerwalls in cold areas of the world. I am interested in adding at least one, possibly 2, Powerwall 2s to my 5.4kW PV system. I live north of Boston MA and it can get pretty cold at times in the winter with limited sunlight. I am wondering how the...

For those of you that have done the 60 -> 75 upgrade and taken long trips before and after. What kind of difference has it made for you? I'm planning a 3k mile route trip next month, that I've done before, and wondering if it would decrease my entire trip time by much. I've tried plugging in...

Hello chaps, total Newbie here (my apologies i know it can be annoying) I’ve gone through some basic numbers and it’s looking like the savings would be pretty big if I were to move to a Tesla. I currently have a Bmw M4 (weekend toy which I occasionally use for work too) and a Honda Insight Mk2...

I am getting my 2014 S 85 delivered next month and trying to get a jump on the charging setup... I currently own an EV that's juicing off of a dedicated 30a/240v line-charger on a daily bases... Questions: #1. Is it ok to install the NEMA 14-50 in place of the current 30a outlet? #2. I know...

We Supercharged our X 100D (March 2017 custom delivery) twelve times on a road trip from Arizona to California. I plotted some of the data logged by TeslaFi. The chart shows kW charge rate versus battery level in rated miles. 100% for me is about 293 rated miles. The Tesla conversion factor is...

Would love to get everyone's thoughts on resale difference between standard and long range. Five years out and beyond. Thanks!

Cable Organizer! I've been checking to store randomly for months!

Does anyone know how I can make this charger work? Fred Meyer | Albany, OR | Electric Car Charging Station | PlugShare

Noticed last night that my car charged to 80% 239miles. Then while left plugged in overnight when I got in the morning it was down to 233. is this normal?

Hey guys, I have a 75D so it's irrelevant but for those of you with P90DL or above.. when you activate max battery power and it preheats the battery, what temperature does it indicate? I'm trying to imagine at what outside air temperature and how long the car has been driving to get the...

I have a first Gen 70D. When full my battery says I can go 381 kms (237 miles) My 70D has 68.8 actual usable battery. This means the calculation to come up with 381 is a slightly optimistic 180 wh/km (288 wh/mile) Based on what we know about some of thr other Tesla battery actual usable...

I have two Tesla's; a MS and a Model X. Both are 75d and both were built in 2016. At my home charger the Model S charges at 3 miles per hour faster than the model X. I get 28 miles per hour charge with the X and 31 miles per hour with the S. Is that normal and should be expected or is that an...

In today's National Post driving.ca section, David Booth spews off about the dirtiness of EV vehicle battery production. Motor Mouth: A few more inconvenient truths about EV CO2 emissions The study quoted is by the University of Michigan ( heavily funded by the Auto manufacturers ). In his...

Motor Mouth: A few more inconvenient truths about EV CO2 emissions So the comparison wants to utilize all the upstream energy costs to produce electricity, but none of the gasoline's upstream costs? It is glaringly obvious that the gasoline arrives at the pump, only after a huge expenditure of...

Anyone here have a Model X Founders Edition? If so, can you post a picture of your battery, assuming it's the original battery that it came with? Thanks,

Tesla needs to add more options for charging. For us in cold weather states during the winter having the charge end at a certain time makes a big difference in range and regen. Currently when I get home I have to turn off scheduled charging, plug in, go back in car, let it ramp up and calculate...

Took my March 2017 Model S 100D in for a simple 12,000 mike service (annual maintenance). Absolutely no issues with the vehicle prior to taking it in. Received a call the next day that whole “pulling the logs” they noticed something odd with the high voltage bus. It wasn’t enough to ever...

I guess I should have read the release notes. At first, I did not get why CHILL was displayed above the speed limit. In fact, the Chill mode also limit the regen. Significantly (like when the battery is cold) So CICO Chill Out Chill In Now you know.

If a driver is going to commute daily a longer distance, such as 40-50 ea way to work. Can the driver configure charging to a departure time of 6:30am weekdays and 8:00am weekends? The idea is: Charge to 85% ,ending at 6:30am from M-F Charge to 75%, ending at 8:00am S-S Charging warms the...

Last night on the way home from work I noticed reduced regen and it was only 43 deg. F. (6 deg. C) This is my first winter in this car. My impression was that reduced regen only kicked in when it was near freezing 30 or below. Is this something abnormal or within specs? And why on earth can't we...
