Batteries

I know that during Florida hurricane, Tesla temporarily upgraded the 60 battery to allow drivers to evacuate. Since then, I heard that Tesla would upgrade the 60 because they no longer make that and know you need a bigger battery for long trips. Has anyone heard anything about that?

I’ve seen it discussed that charging will warm the battery up to allow for better temperatures for winter charging. Also I’ve read that charging before you drive can help you preheat the pack. But is it possible to keep the pack warm all the time by keeping the charge rate around 10A~...

Hello all! I am driving for the 1st time my Model X from Chicago to Orlando (1,200 miles). Planning to stop 5 times with roughly 190 miles on average between superchargers. My question to you is: - How long it would take to charge it back to 100% from ~30% (my estimate we will have left in all...

I just saw an advertisement -- here -- for "SmartCharge New York", a Con Edison-sponsored program which claims to reward EV owners for charging off-peak (with beefier rewards, during the summer months, for never ever charging on-peak within Con Edison's service area). Rewards seem to basically...

I recently purchased a new Model X P100D a few months back with VIN 5YJXCBE47HF039565 and it came with the standard charger. I wanted to upgrade to the 72amp charger and got one from the forum here from another member. I was told by Tesla that it can not be installed due to a firmware...

Range anxiety is a concern for new or would be EV drivers. A friend of my though of an idea that could help and it is allowing Tesla to Tesla jump charges. The car already has ability to charge using DC at up to Supercharger rates, so it may be possible to have a direct Tesla to Tesla battery...

when will it hit the the S&X, any guess?

Do Tesla sell the 18650 batteries with a Tesla logo on them? I'd love to buy some for flashlights, etc, more as a talking point than anything else. I have a bunch of 18650 flaslights, etc. (Fenix are great.) I swear I've seen some on photos, but can't find them anywhere...

Can't seem to get a clear answer on this. The ability to win back energy during braking is one of the nicest feature of EVs of course. However, many cars spend a lot ot time getting stuck in stop and go traffic each day. Therefore my question. See if you can fault my way of reasoning. During...

Question for actual owners, how big is the cable. The reason is my car will be in the driveway but my NEMA14-50 plug is in my garage (and garage too small to fit the car!). So I need to plan how the cable will go through. With my previous car (2013 Volt) the cable was small enough that it...

I am soon to be a Tesla owner and coming from a Chevy Volt I wonder what I need for home charging. I have a Bosch 240 volt level 2 charger in my garage now for the volt. I assume the plug on the cord will not work on the Tesla. I have a electrician friend I will ask to install what is needed to...

To Where'ere Our Hearts Shall Thrust Us When a man finds the vehicle. You know she's the apple of his eye. If he lets you have a peep at it? You're cool. If he permits getting up close to touch and tinker? He respects your opinion. Find yourself in the passenger seat along for a ride...

Current 85D owner. Extremely happy with the 85's durability (still charges to 265 RM after 2.5 years and 36K miles). However, our road trip use cases (300 miles to Mammoth ... in winter cold or with summer bikes) and Palm Springs (280-mile RT day trips) make a 100D enticing. In 2016...

How about a limited battery that occupies the frunk and is based on a chemistry unlike the main battery? Prior to owning a MS, I owned a Chevy Volt for 4 years. That car would regen regardless of the temperature. Of course the car would quietly charge only to about 80% and then report full...

How much do you think batteries can store in 5 years, and how cheap will they be? Will there be a P400?

Hi, I decided to use power tools to measure the KW pulled from the battery on my Dec. 2104 S85 AP1 with 33k miles and ver. 2017.42.a88c8f5 The battery was at 80% and outside temp was 66 F, AC off, only me in the car, no cargo. Power tools reported 303 KW max, multiple runs and the same...

Tesla Model S Battery Modules for sale

If a financial services professional(s) could be consulted on their practices in designed surveys so customers can self select themselves into different risk pools by their varying risk preferences and discount rates, the acceleration and deceleration times (or other subtle) features programmed...

What if some genius devised a diesel gen-set that could be mounted on a flat bed trailer to charge the battery on a an electric semi-truck so they could use the cheaper non-taxed off-road (red) farm diesel to move loads on public highways? Does Tesla have a position on the issue? It is...

So, I'm a Southern California Edison customer. I have solar panels, but only generate about 90% of my electricity. I typically have a $40 per month electricity bill (averaged over 12 months.) I typically use Rate1, and sometimes Rate2 on my current Tiered rate plan. There is an EV Time Of Use...

I was at the Oxnard supercharger and had issues. I arrived at 45% was planning on charging to 90% while I was at the mall I get a notification on my phone that charging has interrupted at 80% my phone says the charging will start momentarily I go to the car and it still says that. I...

I am doing a project for my graduate degree and I need some information regarding Tesla power electronic drives. Do tesla cars have braking resistors for use in emergency in case there's too much current going into the battery too quickly? This could occur if there is an overdriving load beyond...

Leap forward a few years. If there are megachargers, or the equivalent, where you can charge fully in just a few minutes, will we start using Gas Stations as charging stations? Home charging is still convenient, but will we one day see charging pumps out front of the service stations instead...

Has anyone ever noticed a stinky smell entering the cabin when you give your model s full throttle for a moment to speed up quick? I can't tell where the smell comes from is it from my batteries or motors or cables heating up or operating near peak performance doing this or am I imagining things...

The onboard MS charger has a max capacity of 40 amps. This can be satisfied with a 50 amp receptical (80% of 50). As far as I can tell, the M3 has a max of 32 amps. I’m getting a M3 and was assuming I could install a 40 amp receptical of some kind to meet the 32 amp max (80% of 40). I have...

I was just told that my p85 high voltage battery needs to be replaced. Does that mean the actual battery pack? I hope it’s not too stupid of a question.

So apparently an adapter has been made to allow a US Tesla to charge from an EU super charger. Does anyone know how to make one? Pin out diagrams? Or if they are commercially available, how much and where to buy? Interestingly, it is apparently also possible to do a full conversion from US...

This is currently posted on the PW FAQ: Can Powerwall charge my Tesla vehicle or an EV? Yes, Powerwall can provide stored solar energy to your EV through your home electrical panel. However, there is no direct connection between Powerwall and the EV wall connector. Powerwall FAQs Color me...

We will be taking the S 100D to a cabin in Tahoe this January. Most nights are between 10-20*F. I understand it’s best when really cold to leave the car plugged in overnight so the battery can manage its temperature better. Will the people whose cabin I’m using see a huge spike in their...

My car is in production and hopefully will arrive before the end of the year. It will be my first Tesla and I'm really excited to get it. Is there a way to automatically keep track of the charging? I think it would be interesting to see at the end of the month how much juice I used and at what...

Has anyone tried the Vtech chip that is supposed to increase range by 10%? Also performance as well? They claim it is undetectable by Tesla?

My car (S85) is currently at the service center for limiting power on extended drives (30+ min) even with high SOC and ~70 degree F weather. Anytime I floor the car after driving on the highway for extended periods, I get an instant yellow dotted line that limits power which quickly disappears...

I've had my MS 75D for a few months. Got it late summer. I have roughly a 15 mile commute (each way) to work. During the summer, I'd have to charge up roughly 1-2x per week depending on what errands I ran outside of work. Wasn't a big deal. Now that it's been getting cold-ish (we have had a...

hello i am form UAE/ dubai , i am considering buy the tesla MX 100D the Full option . with 20 rims the questions and concerns . 1- if i am in full charge with A/C on all the time and driving in high way speed (120 km to 130 km) on miles (75m ro 80m ) what is the range the car taking on...

john pane is our lone BTX7 contributor to the Performance Metrics. Interestingly his BTX7 battery (part number 1119235-00-A) coded with upgradable battery option code BR05, has been out performing the BTX5 batteries with similar torque and maximum power specifications. Today he came across...

Forgive me if the answer or topic is discussed elsewhere on the forum. I searched both the main forum page and the MS forum, but did not find a sufficient answer. I just received the "Replace the 12V battery" notification. I live in Louisiana and the nearest service center is located 3 hours...

I know that it's recommend that you don't supercharge when you don't need to for the sake of battery wear, but how about using the full HPWC capacity? Is daily 72 amp charging ok, or is it better to keep it lower unless you need a quicker charge?

I haven't seen anybody comment on the price difference between the 300 and 500 mile semi. If we assume a 1MWh pack (I know it's probably a bit less) then there is a 400 kWh difference and $30,000 difference from the expected price. Elon said a while ago he was targeting less than $100 per kWh.

Just Kidding! I’m guessing if it was offered to keep it “topped off” at home for private owner, adding 1KW/hour to an empty 1MW battery (with 25% loss) only short 5-6 weeks to fully recharge. ;) More serious note: if this becomes an RV chassis in a few years, my calc says empty to full on a...

I have put a 50amp breaker in the garage, 240 outlet, the onboard is set to 40amp. I used to get 28, 29 miles per hour charging, but the last few days its only been 12-14. Am I doing something wrong? Software is still the .42 version. And the Tesla App won’t always connect to my car...

Did you upgrade to 75D?

Hello everyone, first post and wish it was under better circumstances. This may be a bit of a long post, so please bear with me. I took delivery of my '17 S75D in spring of this year. For the most part, I truly enjoyed ownership- lack of autopilot parity and some build quality issues aside...

The three white ones are all belonging to the same taxi service. They are ALWAYS at this SC. I've not once been here where there hasn't at least been one. In this occasion, I charge very slowly and I can't help but to wonder if it's because of the number of cars. It just has me questioning...

The new Tesla Roadster has a 200kWh battery. The car is a four seater smaller than the S. I can't see how a 200kWh battery using the cells in the S,X or 3 could have been fitted in it. Does this mean it is using a more energy dense cell? If yes then we should expect that cell to migrate to the S...

I have a 2013 that came with the dual onboard chargers. I seem to remember that I should be able to charge up to 59 miles per hour with a HPWC. I just picked one up, which I think is a Gen 1 as it says use 3 gauge wire and I understand the newer one recommends 2 gauge. What size circuit do I...

Just wondering how come Nema 6-15 is not available anymore in Tesla shop. I saw in several youtube videos that some model s drivers have this adapter being used with the Quick220 systems. Is Nema 6-15P compatible with Model S? thanks.

I've seen some references to not letting the car sit at 100% (plugged in or not) KMan's video also references that charging to max is fine, "just don't let it sit that way for long". Well, what's too long?? And at what temp? For example; overnight (say 8hrs) at 100% and subfreezing temps? Are...

Hi guys, In preparation for Holiday traveling, I set My charge limit to 99% last night. When I woke up this morning at 7am, i found that the car was still charging at 1kw at 97%. This was from an 85% SOC and charging scheduled to start at 3AM. The car sent me the notification that charging had...

Still waiting for my December delivery of my MS. Was thinking of mounting my 50amp outlet into the ceiling of my garage and mounting a shelf, below it, for the charger so it doesn't hang on the plug, causing it to pull out. Then coil and hang enough of the cable so it dangles about 1-2' below...
