Electrician here. A huge advantage of the Wall Connector over the mobile connector is that it requires one less conductor than a regular 240V outlet. It has built in GFCI protection etc. that make this possible. Only need two hots and a ground instead of two hots, one neutral and a ground. I would recommend the Wall Connector all day long over the mobile connector.

I have done nicely with the mobile connector on a 110v circuit with my 22 M3LR, and for grins, I schedule charging to 80% only between 3pm and 8am as my utility suggests to be kind to the grid. Even if I plug in weekly all is fine. I do have the advantage of being retired and most driving is local trips. Even for road trips, I don't charge to 100%. For road trips, it is optimum to keep the battery as low as possible for efficient charging. Before and after delivery, so many insist having a 220v optimum is mandatory. I didn't think so then or now. Understanding one's use case is essential. Contrary to common belief, it has nominal impact on my electrical bill which last month was 2813 kWh of which 88 kWh was my Tesla for 3%. Friends think the neighborhood lights dim when I plug in. :)

I would also add that if you have a high amperage wall connector that you can still charge at a lower rate. B y lowering the rate you push less energy into the pack and it just extends the time. So in Andy's case of needing a 40% charge, he could lower the amperage from 48 AMPS to 20 AMPS and still have a full charge by 7 am. I personally set my car to charge at 18 AMPS because that comes out to 15 miles of range per hour of charging.

Really informative video, Andy - thanks. FYI, my Tesla service center recommends "recalibrating" your Battery Management Unit every month or two months. This is done by charging to 100%, discharging to below 20%, then recharging to 100% again, which is then followed by normal driving and charging levels of 80%. They said doing this recalibrates the BMU controls on the car enabling it to make better estimates. Have you heard this before?

I took delivery of my 2024 MYRWD 2 weeks ago. As I was wrapping up my paperwork I was told that Tesla had just issued recommendation to charge the battery to 100% once per week to ensure the algorithms for battery management retain ability to charge to 100% of the battery capacity. I’ve tried to independently verify this information and have not been able to do so but what you just said synchs mostly with what they told me. But the once a month makes more sense. Regardless, it seems there is something to this.

Thanks for this. I find it's interesting the techs have similar recommendations. Perhaps Tesla should include this info in the app or on the Charging screen of the car. For the first two years I had my M3LR, the recommendation was 85% for daily driving. I had only one instance where the BMU went crazy; on a two-hour drive, the remaining charge level began to drop dramatically - like a leak in a gas tank. It freaked me out for a while, so I pulled over, put it in Park and rebooted the computer. When the car restarted, the BMU showed the correct percentage remaining. Now I reboot after every OTA update, just to be on the safe side.@@srmtn1

​@@mikeforwarduk LFP charging to 100% is ONLY recommended because the BMS needs to be recalibrated -- Tesla doesn't want the BMS to over (or under) charge or over estimate the range available. Charging to 100% is bad (varying degrees) for ALL Lithium chemistries, LFP included. Unless you are going to make a trip where you need to know the battery's charge ~exactly, it's not a big deal. Most daily drivers can easily do what they need to do using the 20-80% range of their battery and decrease the degradation of their battery -- and never touch the parts of the charge where the calibration matters. Recalibrating once a month is entirely adequate for 95% of drivers.

Great video. All of what you said makes sense. I've been telling people the easiest way to protect your battery is to charge with a 120V outlet for a while now. Keep your battery above 30% (why PHEV's don't let you "EV only" below 30%) and below 80% excluding road trips. Let's be real. Most drivers are home >12hrs per day. That means 24 - 36 miles a day. If you're only home 12 hours a day using a 120V outlet. Most people are home longer than that. Most people drive about the American average of 37mi/day. That means you'd need to use a level 2 charger roughly 1 - 3 times per year. But no one wants to talk about the feasibility of 120V charging. It's not cool. It's not expensive. And it's something everyone can do as long as they aren't in an apartment that has no outside plugs. Then, Plugshare has tons of free level 2 charging you can easily charge your weekly drive in 3-4 hours once a week.

One problem with charging at too low amperage is that it keeps the battery temp higher for longer because it takes longer to charge. There is a trade-off between amperage and length of charge. I read a white paper earlier this year that suggested that 30-32A provides a good balance, charging the battery at low enough amperage to not overly heat the battery pack while charging, but charging it quickly enough that the battery doesn't remain at elevated temperatures for hours-on-end while charging. I only use about 25% of my '23 MYLR battery pack on my commute, so I typically charge to 62% at 30-32A. When combined with scheduled charging, this keeps my average SoC at

Tesla now recommends NOT charging every day, and NOT keeping your battery pack at a high SoC. I recently had service done on my 2018 M3 and I was proudly telling the tech that I charged daily and was careful with the battery, and he told me this. He said the best practice is to charge to 80 or 85, then pull it down to 30 or below (percentages, of course) before charging. This utilizes the lower part of the pack which otherwise would always be charged and thus could affect the health of the cells. So I charge to 85 and drive to 25 or 20. I have done this from the beginning for my 2023 M3 and I hope the battery degradation will be minimal over the years. My 2018 has over 105,000 miles and it has lost 10-12% of range.

You should understand there is no "lower part of the pack that doesn't get utilized" in your battery, it's not like a liquid filled tank, it's a battery with a state of charge measured in volts, not actually tank full of electrons. The charge is stored throughout the battery cell in layers upon layers of graphite and polyolefin. Not to mention, if you are taking the estimated range and dividing by the estimated SOC, that's very much only an estimate of battery degradation. The only accurate way to measure degredation is to have known the initial capacity of the pack in YOUR car (they are all slightly different) then fully charge and measure the capacity used on a full discharge. I designed li-ion batteries for the last 20 years, this is the only accurate way, not by using any type of electronic fuel gauge.

Yeah… that’s not how any of that works. Lithion ions exist in a chemical solution, and at 50% SOC they are at equilibrium and relatively equidistant from both anode and cathode reducing chemical reactions at the electrodes. A battery is happiest at 50% charge and you want to maintain the band so that it is the most narrow around 50% what you were doing is increasing what’s called depth of discharge which is related to increased battery degradation.

Because I have solar and Powerwall for home, Tesla allows me to charge 2022-MY Long Range(80%) and 2023-M3(100%) on "Solar Energy Only"(other than house usage). So, it is slow charging. In the morning I let the Powerwall recharge to at least 80% after overnight usage. Then let the solar charge the EV. I live in San Diego, where there are a lot of sunny days! Other than some winter days my house and EVs are totally off the grid. Keep in mind, make sure Powerwall has enough energy for your house during the high peak(price) hours, 5pm - 9pm.

The way I look at it is if you work 8 hours a day 5 days a week that means you’re likely home most of the rest of your days so you have around 12 hours home per work day and then weekends. You can easily charge 240-300 miles during your 5 work days and then weekend anytime you’re home. The avg driver drives 12,000 miles a year which is about 230 per week. 120v is more than enough for the average person. Plus if you can charge at work it’s even better.

I drove my 2014 P85+ Model S for 10 years before unfortunately totalling it in March, but saw less than 4% battery degradation over the life of the car by applying very similar charging practices as described here. Back in 2014, Teslas came with free Superchargering for life, but I only used it when necessary and preferred Level 1 and Level 2 charging for my daily driving. One thing not mentioned in the video is that Tesla allows you to reduce the amount of amperage drawn while charging, which perhaps further reduces heat. Being able to reduce amperage drawn is also helpful in situations where you might not be on a dedicated circuit and don't want to trip (or risk tripping) the breaker. I'll miss that beautiful OG Model S, but just took delivery of a Cybertruck a week ago.Too bad Tesla didn't include free Supercharging on the Foundation Series trucks (even though I don't plan to use the chargers much).

Andy I would recommend that owners choose a HARD WIRED set up like I have with my Bolt. An outlet, especially a poor quality outlet is adds another variable that can go wrong with charging. I’ve seen many outlets melted due to poor outlets or under torqued lugs holding the leads down. For owners that install an outlet, the least you could do is double check the outlet occasionally (yearly) to make sure they are still torqued. Simply feeling it for heat can give you an early warning if there is a potential issue.

You are correct, Charging Lithium chemistries slower is a battery saver, Pushing the max amount of amps into the cells causes cathode swelling, this causes battery degradation. I've found this on stationary batteries which are the same concept....... LFP also does not like being charged to 100%, but if you compute the voltage needed to keep the cells in the flater part of the charge curve your LFP will last very very long.... With increased SOC's and High temps are a dendrite accelerator which is most certainly battery cell killers, sometimes even detonators....

@@The_DuMont_Network Yes, but you decrease the current by decreasing the amps (the rate of the current flowing) in your app or on your screen under charging. There is no adjustment in the app or on the screen where you "decrease the current". This was a discussion on practical things to do to keep your battery healthy. Charge to 80 %, charge in cool weather, turn the amps down on the same screen the charge limit is adjusted. Keeping it simple. Most Tesla owners know this, some new to EVs don't.

If high summer temperatures are bad for supercharging a NCA battery, why does the trip software "precondition" the battery for fast charging at a supercharger? I presume the "preconditioning" means that the battery is warmed to accept a faster charge?

I agree that 120 V charging can be sufficient for people who average less than 30-40 miles/day. Record your total milage for a week or two to see what your daily average is. If going that route, I highly recommend replacing the $0.64 "builders spec" outlet with a $1.89 "commercial grade" or "industrial grade" outlet. These outlets can handle the continuous high current needed for EV charging with less chance of burning or melting.

My wife and I have had 5 Teslas since 2019, three model 3s and two model Ys. I have followed all of these charging practices since the very beginning, and all of them ended up the same: roughly 10% capacity lost by 30k miles or so. I did keep the first model Y until about 45k miles, and it was the lowest of the bunch: just under 90% of original capacity. I am not sure how to reconcile when people report they have only lost 2% or even 5% as that is not our experience across a decent number of batteries. However - we do live in a really hot area, where temps can be over 100 degrees for over 1/3 of the year. That may be the only reason there is a discrepancy between what some people experience with degradation and what we have. Still, many times I am left wondering if all the effort to follow these rules really mattered. ie, my wife's model 3s were used a lot for traveling and did a decent amount of supercharging yet they did not degrade any better or worse than our other "home charged" cars. /shrug

@@LuKiSCraft Most simple would be to take the miles remaining and divide it by your current SOC. Our Model 3 LR currently reports 139mi remaining @ 42% SOC. 139/.42 = 330mi. that should be the 100% range. Since the car new was 353 miles, 330mi is ~94% of its original range. However, Tesla includes a buffer below zero in their total range which confuses things. I am not sure what that buffer is, but it might bump that 94% up another 3 or 4%. I actually go by the consumption meter, which as far as I know does include the below 0 buffer. I look at the 30 mile average, multiply wh/mi by estimatated range remaining, then divide it by the SOC. those numbers however are only estimates by the BMS, so usually the most accurate way is to drive or burn the battery down from 100 to 0 and measure how much energy was expended. but that's a lot of effort.

I got a 2022 Model 3 Performance, i only charge at home or at work (we have free charging for employees). For my house I ran a 240 volt line from my dryer in the backmof my garage to the front next to the garage door and i also made a hole on the side wall to the outside and installed a small weather proof box over it on the outside. Then i bought a second portable charger and the correct adapter to plug it permanently on the new 240 volt outlet and have a small hook to hold the charger right there. If i want to charge insode the garage, i just use it. If i want to chatge outside, I pass the charger to the outside using the hole I made and charge outsode wothout having to open the garage door at all. I rather charge outside most of the time since I usually keep one of my cars in the garage (a sports car Nissan 300ZX). So the cable is usually rolled inside the box I installed outside. The only catch to my setup is that i cannot use the dryer and the charger at the same time as the line is not meant to be for that and the breaker would jump. But that is no problem for me since I charge over night at home and laundy is done on weekends during the day. And since i started to work on a new job, they have free charging stations for employees so I just charge there every day, barely use the charger at home. As for the charging habits, I always charge to 80%, my commute is short, so i spend about 5 to no more than 7% battery each way to work, plus another 3 to 5% for the Sentry mode while parked at work. Since I charge there, my Tesla barely sees 80%, about 3 to 4 hours per day only. The rest of the day and night is at about 70 to 75% average while parked at home. So 99% of my charging is Level 2 charging (240 volt). As for Superchargers, I only use them when needed while going on a trip which is not often as we usually use my wife mini van (Kia Carnival) since we have 3 kids. After 2 years of owning my Tesla, it os about to turn 10K miles on the odometer so it is practically new and the battery should be virtually in perfect conditions too go en the way I charge. Hopefully my next Tesla will have a better battery, and perhaps the one after it will have a solid state battery if that becomes the norm which I'm sure will happen. Then range will be probably close to 800 to 1K miles, charging will be done in a few minutes on Superchargers, and the battery will not suffer with full charge nor with very hot or cold weather due to the solid state of the electrolytes. By then, I would think in about 10 years or so, ICE vehicles will finally start to fade out as people will no longer have excuses since there will be no range anxiety nor weather anxiety. Cannot wait for such EVs to hit the ,arket, mostly, Tesla. Cheers.

Even though I don't own a Tesla (I have a 12 year old Leaf that lacks thermal control) if you baby the battery it will stay good a lot longer than warranty or the usual 10 year caveat. What do I mean by baby a battery: 1) I never have fast charged it even though I could, I've only done level 2 charging which is adequate given the Leaf's mileage limits; 2) keep the car garaged and less elements thermal change (if your battery lacks the active thermal control or you want to lessen the draw during down time); 3) if you full charge don't leave the battery at that state long (I always drive hard to make sure if at full charge to stay below 80% if short trip); and 3) for long periods (I'm talking a week or more) only keep that battery at or below 50% SOC. I'm still on my original battery after 12 years and from my original efficient driving range of 105 miles I'm now down to 65-70 miles and the battery indicates I can still fully charge it. Which is probably because given the Leaf's limited range are all short trips and I charge less frequently than most. In fact it is sort of ironic that my 12 volt accessory battery has been replaced 3 times so far.

Tesla provides the following recommendation in the section High Voltage Battery Information: Model Y has one of the most sophisticated battery systems in the world. The most important way to preserve the high voltage Battery is to LEAVE YOUR VEHICLE PLUGGED IN when you are not using it. This is particularly important if you are not planning to drive Model Y for several weeks. Do I understand correctly that it is better to always keep the vehicle plugged in whenever possible, and that I do not need to disconnect the car from charging even if the battery is fully charged to the specified limit?

Sarah, if you are driving 70 milrd or less a day (commuting), you will be fine with a standard wall outlet. BUT ( MAJOR BUT ). Make sure the outlet into which you plug is not worn. If it doesn't take a little effort to plug in, get the outlet replaced with a commercial grade (like HUBBELL, not leviton, or any Ah So brand). Make sure the conenction is tight, and make sure the plug/outlet doesn't feel warm after a charge session. If you can afford a higher current outlet and get the appropriate plug for your charging adapter (from Tesla),by all means do so. Even a 220V 20Amp Air Conditioner outlet will make your setup more efficient. And say Hello to Grandpa for me. I sure miss mine. And I'm a 76 year old grandpa.

It's also a good idea to not let the car reach the SOC limit you set. For instance, if you know when you'll be using the car, slow down the charging so it's close to getting done by the time you leave. Reason for this is when you let it sit without charging, vampire drain sets in, and that counts towards the battery cycling.

Can you adjust the current draw for your level 1 charge rate? The last EV I rented gave me two options: 8 Amps,(960 watts) or 12 amps.(1,440 watts@120 volts). When I used level 2, the NEMA 14-50 plug, it pulled 30 amps,(7200 watts@240 volts) with no option to adjust. If it were possible, I would have chosen 12.5 amps, for an even 1,500 watts@120 volts. For maximum efficiency, I would measure the outlet voltage, and set the current so it doesn't cause any more than 3 volts of drop compared to unloaded voltage. The farther the outlet is away from the load center, the more voltage drop per amp of draw, just due to the extra length of wire from the breaker box to the outlet. Use an extension cord ONLY as a "last resort"!! An extension cord can greatly reduce your MPGe from "plug to pavement". What kind of extension cord, or even which outlet you choose to plug into can make a similar difference to your mileage per kWh, as adjusting tire inflation pressure. My cars built-in charger drew the same amperage, no matter what the supply voltage was. That amperage multiplied by voltage at the connector, is the ACTUAL wattage being supplied to the cars charging system. The more voltage drop, the lower the wattage, the longer it takes the charge, the more wattage drawn through the electric meter!

One thing you do not consider is the overhead cost of charging at diminishingly low rates. Just keeping the car awake while charging takes several amps at 110v (the contactors draw maybe an amp just keeping the battery connected, plus waking up the computers and "head"). You are drawing those amps for the duration of the charge. If you finish in 3 hrs vice 18, you are saving 15x whatever that parasitic loss is. Also, charging at a low rate doesn't warm up the battery significantly, so the resistance losses are higher.

I came to the same realization, mobile connector + super chargers is plenty even in Idaho, which is more rural than most states.

No matter what you do battery will degrade as it is worn out. It's not a fuel tank. It's a reactor. A chemical reaction goes on it when you discharge it and the same in reverse when you charge it. Just like a combustion engine, it will ware out. But you burn the candle on both ends so to speak.

So 45 to 50% to 80% SOC every night is a good range? My wife’s model Y travels around 70 miles RT a day and this is her % range everything night

I was told every 15 cycles of charge you should charge your battery to 100 percent I have found charging to 90 percent the car and the battery respond the best

98%... that's amazing Andy! My 4 year old SR+ with a little over 14k miles will only charge to 90% of any charge level. For instance if I set my charge to 80%, it will only charge to 90% of that 80%, never 100%. Generally I have it set to 80% unless I plan to make a longer trip. I use a Tesla wall charger.

Wow that’s some nasty degradation. End of life is 85%..

That sounds like your battery is on the way out, honestly. That or there's something wrong with your battery controller. Regardless of degredation, you should still get 100% of your target percentage, even if in reality it's more like 90%. Are you saying if you set the target charge level to 100%, it'll stop charging at 90%? You never see 100% in the car?

If you are on a tight budget you would not own a Tesla, get the best connector for the intended use (likely get both). The wall connector is the way to go for home, especially in situations (like mine) where the wall connector lives outdoors. Also, the NEMA 14-50 outlet can be a (arcing) fire hazard especially if it is not a quality one (like most electricians would use) and you plug and unplug to bring it with you (because you cheaped out on connectors). The car has an 11.5kwh onboard charger get the solution that can use it. It seems insane to buy a $40k, $50k, $60k+ vehicle and then try to save $200 on a the charging hardware you use every day.
