Ought to I Cost My EV Each Evening? Can I Depart My EV Plugged In In a single day?

The next are two frequent questions from new electrical automotive homeowners and potential electrical automotive homeowners: “Ought to I cost my EV each night time?” and “Can I depart my EV plugged in in a single day?” I’m going to sort out them each in a particular BOGO/two-for-the-price-of-one article.

The reply to the primary query is variable, relying on one’s circumstances and preferences, whereas the second query is an easy sure/no query and the reply is: sure — you possibly can definitely depart your EV plugged in in a single day, and most of the people do. It’s comprehensible that many individuals (most individuals?) initially wonder if it’s okay to maintain the automotive plugged in when you sleep. One might fear about fireplace threat, or concerning the likelihood that the automotive might maintain drawing energy and losing cash should you depart it plugged in. Neither concern is value spending any psychological power on, although. Hearth threat is exceptionally low. And as soon as the automotive reaches the battery degree you’ve set the automotive to cost to, it would merely cease drawing electrical energy. Consider it like your air conditioner — when the home is just too scorching, the AC activates and sucks up electrical energy; when the home is cool sufficient, it shuts off once more.

So far as the “Ought to I cost my EV each night time?” query, nicely, that basically simply will depend on how a lot you drive and the way a lot vary your automotive has. In case you have a automotive with 200 miles of vary and also you drive 100+ miles a day, you certainly wish to plug in and cost day-after-day. The common within the US, although, is to drive 40 miles a day. In that case, it actually doesn’t make sense to plug in and cost day-after-day. And from my expertise masking this trade for a decade and speaking to numerous EV homeowners, most EV drivers don’t plug in day-after-day. They plug in each different day or each third day. (Notice: This dialogue is assuming entry to dwelling charging. Not having dwelling charging can complicate issues.) Whereas it’s the norm to not cost day-after-day, there’s no hurt in doing so. Additionally, there are some advantages.

In the event you do plug your automotive in each night time, it turns into a powerful behavior and you might be a lot much less prone to overlook to cost when you should. In the event you don’t cost day-after-day, it’s a lot simpler to overlook to cost on an evening when you should. (Been there, completed that.) Don’t wish to overlook to cost? Plug in day-after-day while you get dwelling and make it one thing you don’t even take into consideration.

One other advantage of charging your EV each night time is that if one thing surprising does come up and you should drive far more than beforehand deliberate, your automotive ought to have a great state of cost for that irregular day. I’ve beforehand written about my choice of holding our automotive between round 30% and 70%, or 20% and 80%. The issue with that strategy — which I’ve run into in minor methods a handful of occasions — is that you're typically at 20% or 30% after which your plans change (otherwise you overlook about sure plans till the final minute). Then you definately don’t actually have the perfect quantity of cost on your day’s wants, and you might not have time to cost as much as the perfect degree. Like I mentioned, I’ve solely had minor issues with this type of slip-up in my 4 years of EV possession, but it surely’s not enjoyable when it occurs and it’d be straightforward to keep away from by merely plugging the automotive in day-after-day. Really, I in all probability would simply plug the automotive in day-after-day apart from the truth that I've 70,000+ free Supercharger miles that expire in a few 12 months (I won't be able to make use of the overwhelming majority of them with my 10,000-mile-a-year driving habits 🙁 ).

The one factor you don’t wish to do (until you have got a LiFePo battery) is cost your automotive as much as 100% day-after-day. In truth, I'd keep away from ever charging to 100%. The extra you retain your automotive’s battery round 50%, the higher. That truly goes on your cellphone battery, laptop battery, and different batteries as nicely. Batteries degrade extra the nearer they're to 100% or 0%, particularly if sitting there for lengthy intervals of time. To be sensible, folks usually suggest holding your battery between 20% and 80%, however should you’re excessive and it’s straightforward sufficient for you, you could possibly even maintain it between about 40% and 60% as a lot as attainable. In any case, if you'll plug your automotive in day-after-day to cost when you sleep, eat, work, watch TV, or chill in different methods, simply make sure to set the cost restrict to 70%, 80%, or 90%, not 100%.
