Batteries

Is this the wave of the future?Until now, battery-pack production has followed the same basic procedure. A company that specializes in making battery cells like Panasonic or LG Chem makes the individual cells and then the automakers take those cells and package them into a battery pack. In other...

So I have had my SR+ model 3 for 6 months and have been consistently getting the full 240 miles while going on long trips. I have normally charged to 85% every three days or so without me downloading a new software update. One random day my max charge dropped to 230 with no early drops. any idea...

We use track data, charging data, and some simple math to estimate results. Our preliminary estimate is that the Tesla Model 3 Performance, due to high battery temps, would not be able to charge at 250 kW like the Taycan at the high ambient temps encountered at the Nardo track. Also, the total...

Tesla will reportedly contract LG to supply batteries for vehicles built at its Shanghai plant. The deal would diversify Tesla’s battery suppliers, as the company currently sources batteries from Panasonic. Reuters, citing sources close to the deal, reported that Tesla is still likely to...

Hi I have had my model 3 for the last two months, and noticed when I charge I dont get as much charged. for example when I charge to 90 percent I get only 209 mi, I believe b4 I used to get 216. I have the standard range plus . What should I do? is there a way to reset the calibration, should I...

Tesla must secure batteries for China market explosion. There’s little doubt Tesla is going to explode in China, but there’s a lot the company needs to put in place. For starters, finishing construction of its Gigafactory 3 in Shanghai. But also, assuring there are battery suppliers in the area...

There’s a lot to like about this battery pack design. The Polestar 2 battery pack layout is very unique. It’s kind of like a marriage between the Chevrolet Volt “T” pack (where GM put cells down the tunnel of the car) and the Bolt EV pack that is essentially a mono-slab pack design with a...

Don’t try this at home. A wise man once noted there are a few things one should never do. Things like pulling on Superman’s cape or spitting into the wind, for example. Now, we would like to add a new item to this list: don’t drill into a Tesla battery cell. As you can see... READ FULL ARTICLE

If BEV charging really an issue? One often reads statements by ICE drivers that they will not buy a BEV until it can be charged as fast as ICE cars can be filled with gasoline; they often state a 5-minutes target fill time. I do not recall ever spending only 5 minutes at a gasoline station. I...

Does the Tesla Model 3 really have the highest energy density? Energy density can either be based on weight or volume. In the case of energy density by weight we need to know the energy of one cell (usually in watt-hours) and the weight (usually in kg). Similarly, in the case of volumetric...

The new battery cell comes with improved chemistry which might result in faster charging and discharging, better longevity, and even lower cost Coming from the Tesla battery research group, this patent promises an incremental step in improving the current Li-Ion batteries that are used in...

Aston Martin says they use 18650 format cylindrical cells in a 800V configuration for significantly quicker fast charging. If you couple similar batteries in parallel you retain voltage, and in series you double voltage. If high voltage is the key to charging, wouldn't it be as simple as to...

Those Tesla/Panasonic cells are simply more affordable. According to UBS analyst Colin Langan, the teardown of lithium-ion battery cells produced by Panasonic/Tesla, LG Chem, Samsung SDI and Contemporary Amperex Technology (CATL) revealed that Panasonic/Tesla cells are some 20% more cost...

Unsurprisingly, batteries are the culprit holding back large volume expansion by the carmaker. While plenty are ready to bash Tesla on short notice, with such a novelty product, it’s not that simple to make all things work. At once. After all, the initial product market introduction and high...

Cross posted from Dangerous Prototypes I think that some folks may gain a little insight into your car's battery by studying this. You may realize that anything that your Tesla shows you as being absolute, as far as range is concerned, should be determined as an educated guess. Posted on...

For those of us in the Southwest, the summer heat is here. I've noticed the vehicle is a bit noisy when I first get in and drive off and presume it is the battery cooling system doing its thing. So far, ,it has been as high as 117 Fahrenheit, based on the thermometer reading on my dash panel...

Hello! I just purchased a Feb 2015 P85D 30k miles, last Saturday and I have some questions about its performance that I think might be abnormal. Since This is my first Tesla I don’t have any prior experience to compare it to. The 240 mile drive home on the highway averaged 350 watt/hour per...

Sorry if this question has been beaten to death. I live in the US and have a model S. Just wanted to know if there is a better charger to get than the one Tesla offers. Thanks. - Eliot

Recently, sometime in the last 4 months, my max battery power @90% @5 minutes from max battery ready(i.e. not fully warm but close) has dropped from 458KW (1535 amps * 298 volts) to 336KW (1535 amps * 284 volts) (+- a few KW). It seems like it must be battery degradation since the current...

I'm doing a bit of travelling now and don't have access to an outlet that I can plug in over night. The temperatures are about -5C and I have a long journey tomorrow. I've decided to charge my car up to 95% and leave it parked outside overnight near where I am staying. I know it's not good to...

Last time I charged to 100% last year, it held 80 amps all the way up to 99% before tapering off to the "calculating remaining charge time" when it would drop to 20 amps or so for that last little bit. This time it dropped to: 72 amps / 90% 43 amps / 93% 40 amps / 94% 23 amps / 96% 16 amps /...

I read the news that Tesla is giving away free chargers to employers to facilitate work place EV charging (Tesla launches a new ‘Workplace Charging’ program to supply free charging stations to businesses). My current employer (Capital One) leases a few buildings in the area, that means to get...

A brief article, well written and well explained: Ultracapacitors, graphene, nanotubes: BBC sees the future Fancy charging up your electric car in 10 minutes?

Please, I'm looking for knowledge, not guesses. I'm planning a trip in a couple of weeks to a friend's cabin, and I'm wanting to know what happens in "worst case scenario". First off, I can't make it from the nearest charger (Tesla or other public) and back again. Just not possible. So I...

So I've been carrying around a 50' 15A 110V cord (NEMA 5-15) for 110V charging with the Telsa Mobile Connector charger when overnight on the road and am going to buy a 30 foot NEMA 14-50 cord to give myself faster charging options when 220V 30-50A is available. I realize I'll need adapters for...

Road trip experiences seem to be scattered throughout the forums, so I guess I’ll park mine here. Maybe others can see what I did and do better or get an idea of what worked for me. This first post will show a trip from NJ to Western PA. This was my first time driving a MS outside one test...

For daily commuting always plugged in at night set yp 70-80% what should range mode and always connected be set to for ideal use? I have heard for a trip to turn always connected off and rangemode on but the opposite for daily commute-its confusing. In colorado where temps go from 20 degrees to...

Hi team, i'm keen on looking at options to access the 100kw battery on my model x p100d, would be a great source of power for camping trips etc. Can anyone recommend an auto electrician in NSW that might be able to help me with this? Even better if anyone has already done it and might be able...

Just want to get some opinions here. With the crowding issue at the supercharger at times, will fast charging on ChaDemo or CCS ever catch on, especially on Tesla cars? I am guessing no due to the high cost? EVGO is charging nearly $10 an hour, Chargepoint is even higher.

Since they have a ChaDemo adapter, will there be one for CCS? Just curious.

I haven't tried this but is it possible to lower the charging amp setting while supercharging?

Hi My one year old Model S had an error message on 10th January, and was unable to receive a charge. Tesla collected the car and declared that it was a HV battery fault and that we would need a replacement. It is now the start of March and my car is still with Tesla. I have been told that in...
