If you compare it to 750 HP trucks, it's cheaper to buy, and electricity is cheaper than gas in most areas.
If you are buying an EV to save money, it's not a wise decision. If you are buying one for performance, then it's a good decision.
I have confidence in Rivian as far as startups go. They have put a lot of Captured Test Fleet vehicles on the road for quite awhile now. Some of the EV companies are not as careful. I'm driving one of them... ;)
It doesn't have to be 9 kW, and yes, you can pull wire. What you CAN'T do is pull 120/240 volt wire in the conduit.
Essentially, to set up a commercial lot with 240v you must cut through the pavement and trench it. That's why you don't see much L2 charging in parking lots.
Here is what I'm hoping for: That Rivian has an excellent automotive HR staff and an excellent 'buyer' with heavy auto experience. Many folk do not realize how important the buyer (procurement dept) is to a manufacturer. Talented buyers are a critical team member. This is one area that Tesla...
There is a huge unknown right now: The Chip Shortage. Established supplier chains have a big advantage over startups since they often have large contracts with redundancy and punishments for not meeting deadlines.
I hope it's not an issue, but it could be.
Here are the advantages of designing 277-capable EVs:
Many locations are 277 only. Parking lots and light poles come to mind. Allowing L2 charging during the day at light poles at the back of the lots is a great way to extend infrastructure for very little money.
208 and 120 are...
I state performance numbers that way to make the math easier. Both are correct. But sometimes people will try to divide by 33% or 67% to get the performance improvement. Both are wrong. They need to multiply by (1+33%) to get the right answer.
In the US, we use the following 'low voltage' AC services that EVs can digest:
120 vac - This is found everywhere, homes, businesses, public buildings. It is seldom found in parking lot lights and street lights.
240 vac - This is also available at houses and apartments. This is usually not an...
People use "free" communication services because they are exchanging their personal data for something that they want.
What if Rivian provides you with some perk to allow the use of your driving habits, such as where to locate Rivian DCFC charging sites? Would that be worth it?
It's hard to tell how much the money difference is. You will get at least $7500 off MSRP on the Rivian, sometimes a lot more due to EV rebates.
You cannot option the Jeep up to the same performance levels you find in the Rivian; there is not a Hellcat option.
The advanced driver's aids such...
I'm happy that civil engineers can now have accurate data of traffic pattern and that if I'm in an accident and unconscious, OnStar will send help.
My cellphone is a serious threat to my privacy, my cars, bikes, and trucks are not in the same ballpark. If you think Apple is owned by Mother...
I don't know how many of you have flat towed a 6000+ lb vehicle with no trailer brakes, but it's really not safe. In a panic stop, the rear of the tow vehicle lifts, and then the towed vehicle tries to lift and jack-knife the tow vehicle. Lightweight vehicles aren't that much of an issue...
120±5% = ±6 vac
240±5% = ±12 vac
Stack up error happens with linear numbers.
That's why percentages are better to use than absolute numbers.
And why they tax us on percentage :mad:
Sidebar - The difference in voltage between the split phases of 240 means it's less likely to be at...
