Guest Blog | December 13, 2019 | Clean Transportation, Electric Vehicles

This is the primary submit in a collection of blogs by Dave Erb which can be supposed to demystify electrical automobile (EV) charging, each for potential EV consumers and for new house owners nonetheless attending to know their EVs. 

New Technology; you’ve accomplished this earlier than

Change will be difficult, even when it’s actually good. Remember all of the little belongings you needed to be taught whenever you obtained your first smartphone, like the way you dropped a number of calls earlier than you bought the cling of swiping the display to reply it? It’s straightforward to giggle about them now, however two issues are abundantly clear:

  • The “learning curve” for new technology will be extraordinarily irritating, however…
  • Given a selection, you’d by no means return to your flip telephone or (horror of horrors!) landline.

EVs are so much like that: the little psychological changes they require will be irritating whenever you’re on the steep finish of the training curve. But when you get the cling of them you understand they provide a plethora of advantages:

  • They can prevent large quantities of money and time.
  • They’re extra fulfilling to make use of than the interior combustion automobiles (ICVs) they exchange.
  • They’re higher for the surroundings, public well being, the financial system, nationwide safety, and world peace.
  • The longer you drive them, the extra you understand that they current alternatives you hadn’t even considered earlier than. 

So let’s consider EVs as large cellphones on wheels. People who don’t but personal them are inclined to have numerous trepidations about charging, vary, and power.

When You Need a Charge

Many individuals contemplating an EV fear about how and the place they’d cost one. Just bear in mind, although, inner combustion automobiles usually require that you simply journey to purchase gas that doubtless crossed oceans to get to the pump. On the opposite hand, each electrical socket has the potential to cost an EV and, although it’s doable the electrical energy could have traveled a great distance attending to that socket, it may well come from a wide range of sources, maybe as shut because the sunshine hitting the roof!

So, similar to charging your cellphone, you usually don’t should go anyplace explicit to cost an EV. For nearly all of EV drivers, most charging happens at home: upwards of 80%. Charging at workplaces is changing into extra widespread on a regular basis. Public charging alongside freeway corridors and at locations helps lengthy-distance journey by EV as properly. 

EVs Go the Distance

In the North American market, private automobile ICVs sometimes carry sufficient gas to go about 350 miles on a full tank. Only a number of present mannequin EVs can journey that far on a full cost and those that may are costly. But let’s not examine apples to bowling balls. Charging at dwelling means you possibly can depart with a “full tank” each morning. On the overwhelming majority of days, most of us solely want sufficient vary to go to work, make a number of facet journeys, and have a bit cushion to make sure we are able to get dwelling. Extensive research has indicated that pure battery EVs (BEVs) with as little as 75 miles of vary might exchange giant numbers of ICVs, even within the whole absence of public charging. Workplace charging might substitute for dwelling charging or would reduce the vary requirement roughly in half for drivers with entry to each. Alternatively, plug-in hybrids (PHEVs) can present many of the advantages of electrification with even smaller battery packs, substituting the gasoline engine again up rather than longer BEV battery vary and away-from-dwelling charging.

But what about BEV drivers who dwell in residences, or don’t have devoted parking close to dwelling, or whose employers don’t but present charging entry? How do they discover public charging? Easily with a useful resource like PlugShare, which is obtainable as an internet site and a free smartphone app. PlugShare exhibits not solely the situation of public chargers, but additionally lists the varieties of plugs, networking preparations, and price (if relevant). Many public chargers are free, put in by grocery shops, malls, inns, and others to draw what you are promoting. That’s an indicator of how cheap EV charging actually is. Imagine how shortly these corporations would go bankrupt in the event that they gave away full tanks of gasoline.

People additionally are inclined to obsess about charging time. But that is one other space the place we have to consider EVs extra like cellphones that we already plug in every night time, and fewer like ICVs which require us to cease our days for gas. For all sensible functions, charging an EV takes twenty seconds: ten to plug it in, and ten to unplug it. In between, you’re doing one thing else: consuming, sleeping, purchasing, working, and so on. Re-energizing your automotive solely calls for your full consideration your entire time when that energy is an explosive fluid like gasoline, which could spill and wreak havoc in the event you’re not further cautious.

There is one main exception to charging time: on highway journeys, you possibly can refuel an ICV sooner than you possibly can recharge an EV. But we have to hold issues in perspective. First, many individuals fly when taking lengthy journeys. Second, even these of us who drive lengthy distances want breaks for meals and restrooms. Level 3 quick charging (to be mentioned within the subsequent installment of this weblog collection) doesn’t essentially add way more time to a visit above the stops pressured on us by biology. 

The Electric Cannonball Run

Many auto fans (and B film followers) have heard of the Cannonball Run. Begun in 1971 as a protest against stricter traffic laws, contributors race towards the clock from the Red Ball Garage in New York City to the Portofino Inn in Redondo Beach, CA driving greater than 2,800 miles on public roads. Total time door to door is all that counts. With the current construct-out of the Tesla Supercharger community, EVs are making their very own Cannonball Runs and new EV information have been set twice final summer season. For ICVs, the Cannonball Run has at all times been an outlaw affair, with extremely unlawful speeds wanted to set the report. The present EV time of 45 hours 16 minutes, achieved 31 July – 2 August 2019, required driving properly above the velocity restrict (not one thing we encourage or endorse!).  However, the earlier EV report of 48 hours 10 minutes, set two weeks earlier (12-14 July) by Lars Thomsen, Betty Legler, and their daughter Robin, was achieved at “normal” speeds by good planning and constant execution. Google Maps exhibits a authorized driving time of 42 hours, so the household’s 19 Supercharger stops took an additional six hours in whole, or about 20 minutes each 2.5 hours.

As it occurs, I’ve private expertise with the same cross nation highway journey. In 1970, and once more in 1971, my household went from Roanoke, VA to Berkeley, CA and again.  On each events, the 2,700 mile westbound leg was accomplished like a authorized Cannonball Run. The first time took 53 hours, the second 51. Both journeys have been grueling. Hardly anybody I do know has accomplished something remotely comparable. Nonetheless, the Thomsen / Legler household went 100 miles farther of their EV, in three fewer hours.

So a lot for the inherent inconvenience of EV charging.

If we need to speak about wasted time, let’s as a substitute contemplate the ten minutes spent at gasoline stations twice every week, as a substitute of twenty seconds a day plugging in. Don’t neglect two or three oil adjustments a yr, at half an hour apiece in the event you’re fortunate. And, most significantly, on a regular basis you’d should work to earn the $1,000 per year you could be saving by driving an EV as a substitute of an ICV. EVs don’t waste time – they reserve it, in copious portions.
