How We’re Charging EVs at Stage 2’s 19.2-kW Most at Our Workplace

EV charging charges are sometimes referred to by their easy Stage 1 (120V), Stage 2 (240V), and Stage 3 (400V and up DC) classifications, however inside these classes generally is a huge span of charging charges. Stage 2, for instance, can vary from a 6.0-kW ChargePoint hookup you would possibly encounter in a parking storage to the utmost price of 19.2 kW. For those who personal an EV, you wish to be charging at residence as a lot as potential; it is extra handy and much cheaper that approach. And we predict the candy spot is the flexibility to recharge your automobile’s battery roughly in a single day: name it in 10 to 12 hours or so.

For a lot of EVs with moderate-size battery packs, that is potential with mainstream home-charging choices, such because the ones featured on this roundup. However for automobiles with bigger packs, such because the 131.0-kWh Ford F-150 Lightning, the 128.9-kWh Rivian R1S or R1T, or the 112.0-kWh Lucid Air, you will want considerably extra juice for something near an in a single day cost. For instance, the cost time for a Lightning utilizing a 6.0-kW outlet is roughly 24 hours, and a Hummer EV with its gigantic 212.7-kWh pack would take nearly 40 hours.

How Cost Charges and Occasions Are Calculated

A fast refresher: The speed is solely the facility output, or voltage instances present, e.g., 240 volts and 40 amps equal an output of 9600 watts, or 9.6 kilowatts. And {an electrical} circuit can run constantly at 80 p.c of its rated functionality, so a 50-amp, 240-volt circuit is required to have the ability to cost at 40 amps or 9.6 kW. To estimate an EV’s cost time, take the battery capability, add 10 p.c for losses, and divide by the cost price.

The lengthy cost instances with a few of these newest big-battery EVs on the 6.0-kW ChargePoint items now we have at our workplace prompted us to look out a alternative for the 2 Tesla Wall Connectors we even have at our workplace, each of which had been wired to assist 19.2-kW charging on the Mannequin S, an choice Tesla has lengthy since discontinued. Whereas we have used a Tesla-to-J1772 adapter to cost non-Tesla EVs, that connector is simply rated for charging at half the 19.2-kW most.

We landed on the Porsche Wall Connector, which sells for $1586. Costly, sure, however there aren’t that many choices for the quickest Stage 2 charging. Ford’s Cost Station Professional goes for $1310, Lucid’s Linked Dwelling Charging Station for $1200—each which assist bidirectional charging. Clipper Creek is the uncommon third-party alternative, and it goes for $2195. And the Porsche unit is the one one with a show on it, the identical 5.0-inch touchscreen interface discovered on Porsche’s optionally available moveable charging gear, which is a $1120 choice when buying a Taycan.

Automotive and Driver

We had been hoping we would be able to view our charging remotely by way of the My Porsche app, but it surely seems it’s a must to be charging a Porsche that is in your account to take action. We as an alternative view the power use on the display screen to trace EVs’ effectivity and may look again by way of earlier charging exercise if needed. There’s additionally the potential of connecting to the charging unit’s personal hotspot to view exercise, though we’ve not but been profitable in making that work.

Strive This at Dwelling?

To have the ability to cost on the most 19.2-kW price, three issues should align: your home should have a devoted 100-amp circuit for EV charging, your charging gear has to have the potential, and the automobile should be capable of settle for it. For instance, the Hyundai Ioniq 5, our 2022 EV of the Yr, has a ten.9-kW onboard charger. So, it might probably’t cost at the next price than that on a Stage 2 outlet it doesn’t matter what charging gear is put in. To have the ability to cost a Porsche Taycan on the most price, it’s a must to choose the $1680 choice for the 19.2-kW onboard charger when ordering, or there’s the likelihood to retrofit it later.

However, when all of this stuff align, the cost instances are spectacular: a Taycan with the massive pack will be charged from empty to full in underneath 5 hours, a Lucid Air in about 6.5 hours, and a F-150 Lightning or Rivian R1S or R1T in about 7.5 hours.
