Is It Easy To Keep The Tesla Charged
I of the first questions every mindful Tesla owner asks after taking delivery is: how ofttimes should I charge my car? Is it best to fill up upwardly the battery every night, or are in that location negative consequences to frequent charging that might increase energy consumption or harm the battery in the long term? What are the pros and cons of frequent charging? Nosotros took a await at all the factors, so you don't accept to, and hither is what we found.
Tesla's official stance
The Tesla owner'due south manual for a Model S says in no uncertain terms, "the most important mode to preserve the battery is to LEAVE YOUR VEHICLE PLUGGED IN when y'all are not using information technology."ane It also states that "at that place is no advantage to waiting until the battery's level is depression before charging." If you are satisfied accepting Tesla's position as the terminal word on the matter, then y'all don't need to read any further, every bit that should exist plenty to close this tab. The instructions are more than or less identical for the Model iii, X, and Y. And Tesla has a very skillful point, in that location are quite a few reasons why plugging in every time y'all get home will keep you and your EV very happy. But there is definitely a bit more than nuance to consider, then if you are interested in the details, we would advise you proceed scrolling.
Benefits of daily charging
The near obvious reason to charge every day is to increase the range available to you at the start of whatsoever given outing. The longer y'all drive without plugging in, the less juice yous have left for your following trips. Yet, according to the Federal Highway Administration, the average American only drives 37 miles per day, far less than the range of a fully charged Tesla.ii The Standard Range Plus version of the Model 3, which has the lowest range estimation of any motorcar Tesla currently offers, gets an EPA estimated 250 miles of range on a full charge, or enough for the average American to bulldoze about a full week before depleting their bombardment completely.3 If this was all there was to consider, y'all could skip several days and likely never run into problems.
All the same, the range contained in a brand-new bombardment charged to 100% is not the range you should rely on every day. Equally a Tesla ages, its battery capacity slowly drops, approaching a 10% reduction after 185,000 miles according to crowd-sourced data.four Lithium ion batteries are also damaged when they spend time in the very high and very low ends of the accuse spectrum, which is why Tesla ships the automobile with a maximum charge limit of xc% by default, and recommends y'all stay to a higher place xx% if you lot can.5 Additionally, vampire drain from a Tesla's computer and auxiliary systems can use up a small amount of bombardment every day the machine sits idle, slightly speeding upwards your car's descent toward empty.half-dozen These restrictions might get in seem similar you should accuse every bit often equally possible to continue your battery good for you. Simply even with high mileage deposition, on a low range model, following strict battery wellness instructions, y'all merely need to accuse nearly in one case every four days if you drive average amounts.
There is one more benefit to charging every time you lot make it domicile, and it is non to be overlooked. Tracking your charge level across multiple days to remember when to plug in requires mental effort, and for a lot of owners, that simply isn't worth information technology. It can be easier for some to plug in whenever and wherever they make it, always keeping maximum range on paw for spur-of-the-moment drives, and non thinking about the rest. If that is yous, more power to you! Simply if that isn't, and yous desire to optimize around your wallet and automobile at the expense of your level of zen, there are a few drawbacks to consider before adopting the daily plug-and-play mentality.
Costs of daily charging
One drawback to charging every day, especially in cold climates, is that you will increase the corporeality of energy y'all lose to preconditioning. The chillier it gets, the quicker these losses start to add up. Preconditioning is the term for heating the battery to the optimal temperature for charging, and it is essentially wasted electricity that occurs at the showtime of a charge cycle. If your battery routinely needs to be warmed before accepting accuse, you will save on electricity past charging your Tesla once from 10% to ninety% instead of iv split up times calculation 20% each. Verified owners on Tesla's official forum take noted significant enough savings that some accept elected to drive longer between charges during colder months.7
Another drawback to charging likewise often is an increase to your battery'south cycle count. This concept is pretty nuanced, then let's define a few terms starting time. A bombardment'due south wheel count is the number of times it is charged and then discharged, regardless of the energy used. A battery'due south depth of discharge, or DoD, is the per centum of full capacity each wheel uses. In that location are many, many unlike battery formulae used beyond the globe that notwithstanding qualify equally lithium-ion, but mostly speaking, increasing your depth of discharge a bit can get more full life out of your battery.8 At 10% DoD, a lithium-ion battery tin be expected to endure about xv,000 cycles before its capacity drops to 70% of new, while at xx% DoD, that number drops to nine,000 cycles. Nonetheless, since each cycle in the latter case gets double the range (20% vs. 10%), the bombardment in that scenario gets the equivalent of eighteen,000 cycles at 10% DoD, and is therefore healthier and lasts longer. 10% of a Tesla's range is somewhere betwixt 25 to 35 miles, which is right around what the average person drives in a 24-hour interval, meaning charging every other day will get more life out of your vehicle. Careful though, equally your discharge depth ramps closer and closer to a total 100%, it actually gets significantly worse for your battery wellness, which is bad news for those pushing their Teslas to the limits.
Many EV owners also pay for electricity on a time-of-use rate schedule, significant their prices fluctuate based on the time, day, and season in which they draw power. If this describes you, and you typically plug in correct when yous get dwelling from work, you could be paying a premium to charge your Tesla at peak pricing. Weekend rates typically offer significantly simplified and reduced rate schedules, meaning delaying a charge from Friday to Saturday could cost you upwards to 10 times less on some plans. Fortunately Optiwatt offers a free app that volition automatically schedule your Tesla to charge during off-peak rates.
The concluding reason to consider driving a bit more between charges is that the regenerative braking feature of a Tesla is limited and even disabled entirely at very high states of charge.nine If you are charging your car past xc% every solar day, yous will lose the ability to recapture some of the energy prodigal when you apply the brakes. In this scenario, you are meliorate off allowing your car to spend more of its time in the heart of its bombardment limits, where you can pump upwardly your efficiency numbers by taking total advantage of that regenerative technology.
Summing information technology all up
In the end, Tesla'due south guidance to plug in your motorcar as often every bit humanly possible is designed to continue maximum range under the hood, both so range issues don't bear upon your decision to buy another, and so you don't deplete your battery regularly which is harmful to its long term functioning. About owners will do but fine post-obit this advice, particularly those who push their range capabilities on a daily basis and those who don't desire to recall most following a more complicated charging schedule.
However, assuming you drive shut to the American average of 37 miles per solar day, you can further optimize for your wallet and battery wellness past plugging in slightly less often. Charging once every two or three days in off-height electricity pricing periods volition price you less, by saving on preconditioning and maximizing regenerative braking. It volition likewise increase the life and value of your lithium-ion battery as it ages, past lowering your cycle count and increasing your average depth of discharge.
When it comes down to information technology, only you can decide what charging habits are best for your car. We accept laid out the primary benefits and drawbacks of plugging in every night, and hopefully they are helpful in steering you lot towards an optimal schedule for your state of affairs. Whether you want maximum range at your fingertips, just don't desire to think about it, or desire to squeeze every final cent of value out of your purchase, we at Optiwatt want y'all to be happy in your Tesla, both in the garage and out on the road.
