Porsche Is Now Getting into The 19.2 kW Charging Fray, & It May Not Be A Good Signal


A pair months in the past, I informed readers about Lucid’s plan to supply a 19.2 kW house charger. On the time, I identified that 80-amp house charging is one thing that Tesla used to supply, however that the trade (together with Tesla) has moved away from such excessive house charging speeds. However, with Lucid providing its well-heeled clients fats charging wires, now Porsche is doing the identical.

Porsche’s Providing

Taycan house owners who need to get extra out of their at-home charging expertise can now improve their automotive’s on-board charger to a whopping 19.2 kW and double the quantity of energy they obtain (when utilizing a appropriate stage 2 AC charger). Porsche says this function offers a sooner cost time, extra handy charging choices, and extra peace of thoughts in some instances. The brand new 19.2 kW module reduces charging time from 0-100% for Efficiency Battery outfitted vehicles to a mere 4.8 hours, in comparison with the earlier 9.5 hour timeframe! For these with Efficiency Battery Plus fitted autos, cost instances are much more environment friendly — simply 5.3 hours versus 10.5 in its predecessor!

Positioned behind the entrance trunk space, this new module replaces the prevailing on-board charger and related wiring included with the automotive. So, it’s not main rocket surgical procedure to change out for a sooner onboard charger. As soon as that’s completed, it’ll draw as much as 19.2 kW in case you’ve acquired a appropriate EVSE that may provide that a lot juice.

And, in case you aren’t certain the place to get a quick house EVSE/Station, Porsche has you coated there as nicely. A brand new 19.2 kW Wall Charger Join is now accessible through the Porsche Store, so you’ll be able to have a station in your storage to match your automotive. However, I’ve to warn you that it isn’t for peasants. The wall station and twine are nearly $1600, and that doesn’t embody taxes or set up.

Earlier than you run and order that, you’ll want to get your automotive upgraded first.Improve your Porsche Taycan with the brand new greater capability OBC possibility (half quantity 9J1.044.900.31). The package, which retails for $1,850.15, might be ordered and put in at any approved service middle (for an extra 12 hours of labor). Or, in case you’re shopping for a brand new automobile, you’ll want to possibility it that manner from the manufacturing facility.

Why This Isn’t As Helpful As It Seems On The Floor

I’m not going to say {that a} 19.2 kW charging possibility isn’t helpful for some individuals, however for many of us, it’s only a waste of cash.

The largest purpose is which you can solely drive so many miles from house in a day. Should you’re going greater than the vary of the automotive between night time time sleep classes, you’re most likely going far sufficient from house that you simply want a DC quick charging station, and never a sooner AC charging set at house. For most individuals on nearly all days, with the ability to cost up when you sleep is nice sufficient, and also you don’t want greater than 6-8 kW to do this in 8-12 hours from lifeless to full.

Given the restricted or non-existent advantages to this, the price of really establishing house 19.2 kW charging look even worse. Within the case of a Porsche proprietor who needs to improve, you’re speaking about nearly $4,000 of components alone (the on-board charger and the wall connector). Then, add 12 hours of seller labor (at the least $1,200, however most likely much more). Then, add that you simply’ll want some very large wires and presumably {an electrical} service improve to ship that energy to your storage ($1,000-$5,000+). I’d reasonably spend that cash on tires or house photo voltaic if I had a Taycan.

What this can be helpful for is somebody who mainly drives all day and stays close to house. Uber drivers, supply drivers, some forms of on-call medical staff, and maybe authorities officers working in some capacities would discover this type of house or enterprise charging pace helpful.

A Race The Trade In all probability Doesn’t Want

If anyone needs to waste their cash on sooner house charging they’ll most likely by no means really use, I’m not going to take a seat right here and say they don’t have any proper to make that decision. It’s their cash, and none of our enterprise.

However, that having been mentioned, tremendous quick house charging is a doubtlessly troubling pattern within the EV trade. A Taycan has a battery pack with a capability of just below 100 kWh. A Lucid Air comes with as much as 118 kWh of storage onboard. F-150 Lightnings (not accessible anyplace close to the promised $40k) include as much as 131 kWh. Rivian is meant to finally provide a 180 kWh pack of their vans, and Tesla might provide as much as 200 kWh of capability within the highest spec Cybertruck. The Hummer EV is already there.

It’s these monumental battery packs that can find yourself really making use of those quick house chargers, and the trade appears to be making ready clients who want to go in that path.

However, there’s a giant downside. The trade is already struggling to give you battery supplies and cell manufacturing to construct these big packs. If wealthier patrons suck up the entire battery provide for just a few vehicles that gained’t environmentally break even for round a decade, this leaves the typical purchaser within the chilly after they need to use round 1/2-1/3 of what these battery-sucking luxurious autos take to construct.

Sure, battery manufacturing will develop and finally this gained’t be an issue, however that may’t occur in a single day. It takes years for battery mining to come back collectively and begin, and months to years to construct crops that course of that materials into battery cells. Ultimately it gained’t matter if each fool with cash needs a 200+ kWh luxurious automobile, however it is going to be some time earlier than we get there.

As cleantech fanatics and folks working within the trade, we have to be smarter about this and discourage corporations from making inefficient strikes this early within the sport. Equipping individuals with large bucks to cost luxurious vans (most likely their third EV or extra) isn’t the easiest way ahead in 2022. As a substitute, we must be encouraging producers to work on efficiency enhancements that come by means of better effectivity and technique, not uncooked energy.
