Imagine charging your OEM HV battery in just 16 minutes! I'm curious—wouldn't it be amazing to have DC fast charging available for your vehicle? Many of us might already live near a DC fast charger, making this upgrade even more practical. And here's another thought—would you also consider upgrading your battery cells to achieve, say, a 100-mile EV range with a recharge time of under an hour? Personally, owning a 2017 Prime, I've considered purchasing high-mileage, beaten-up units specifically to swap out parts and resell them. But I'm curious about other owners out there: Are there any adventurous folks who'd seriously consider making this leap and upgrading their Prius if the option became available?
Prius PHV in Japan has supported DC in the past. That's why the port door on Prime is so large. It takes about 20 minutes to go from 0 to 80%. With upcoming new battery chemistry and increased capacity, there has been consideration of the idea to support DC. The big assist in that regard is longer needing a second port to support the ability. Naturally, speed would be limited. But the theoretical future ability to pull DC directly from a large & affordable Na-Ion home battery-bank is an interesting step forward most people haven't ever thought of. That would certainly be an intriguing paradigm shift.
The house uses about 100 kW a week. If I added DC Fast and had 100kW pack I'd easily double triple or quadruple my electric bill every month. I've checked out a few DC chargers and superchargers, and if you own an EV BEV whatever, they are great if you understand how they work and don't have expectations that go beyond what they can deliver. I've talked with a few new EV owners and some of them had no clue about how to charge and probably thought DC fast was free, probably from all the hype about EVs , BEVs. I"m sure there are a lot of charging tricks the Huge packs can use to accept 20 or 50c speeds that could make smaller packs burn up in under a year when exposed to those kinds of throttles on a regular basis and in all the extreme ambient conditions some of them have to deal with, It sure would be nice if all packs were similar enough to previous gen packs that the supply would be semi continuous across at least two, three or more generations, like Gen 2 to 3 Prius. Or maybe even if an upgrade from Lithium to Solid State might actually happen one day. We can always hope.
what about for 100 miles? You know.. the PHEV models... the cells are all the same right? here.. i started this right where you need it. Thank you for these words, I plan to make this available here in the US...
yep I wasn't gonna spill the beans just yet, unless someone else noticed too New Traction battery video from Dr. Kelly | PriusChat Newbie Charging Questions (2017 Prime) | PriusChat
The thing is... most arent out there even thinking about what goes therough my head in terms of what can be done with these vehicles... also willing to bet the first time many will see that video is from my post above
I don't think fast charging for vehicles works quite like fast charging for phones. Some of the newer USB standard allow for the power source to supply higher voltages; 9V, 12V, 15V, 20V etc., and the internals of the device transform the higher wattage it back to 5V, so that it can charge the battery with more amps than the cable would carry if it were at 5 volts. From what I gather, fast vehicle charging uses higher currents.
I follow your logic, i think once you review the schematics of the HV battery and Charging system from a JDM Spec Prius Prime 2017 then the US Spec same year and model, you'll understand how the components from a JDM, once installed will make the US spec fast charging using the same battery.
We have a JDM Prius PHV, which has the ChaDeMo DC fast charger port to the right of the J1772 AC port. I get the impression that Toyota not offering this feature in either American or European markets might reflect their concern about its effect on battery life, as distinct from Japan where cars typically have a very short life (~4 years) before they are either scrapped or exported. I've used ChaDeMo once or twice (see attached photo) just to see what it was like, but I will just stick to AC charging.
I consider it a fools errand. By the time you pay for the car upgrade and pay for your home DC fast charger. You could've bought a cheap BEV. Around here, there aren't any ChaDaMo chargers, so it's a moot point and an exercise in wasting money. This is kinda like that cartoon where a gas station is charging a dollar less for a gallon of gas but it's 400 miles away. So the kid says; look dad - 'I filled up the gas tank', after he get home from the trip. @John A H point yes that really tears up a battery pack, especially an air cooled pack. Now that incentives has been removed and US laws considers the EV portion part of the emissions standards law - it must be warrantied for 8-years 100K miles minimum. Slightly different rules applies to replacements, but they also enjoy extended warranty status beyond the normal warranty constraints. I'm sure that factored into Toyota's decision to NOT bring the ChaDaMo option to the states.
That's an interesting topic. I saw a kickstarter that estimated they would be able to deliver home DC charging for about $2000, by tapping into whatever home storage you already have in place. With the potential of sodium-ion enabling affordable capacity, the possibility of DC (slow of course, around 22 kW) may not be so far fetched within the next decade.
I've never found my slow charging to be too slow. I've always had a full charge when I drive the car.
We can speak about hypotheticals all day long and most kickstarters are 'pie in the sky' that never get off the ground. I'm guessing they want to tap off of something like a Tesla Powerwall - use it like an energy storage tank. The assumption is that you've got a system like that already in place - So I'm suppose to spend another 50K+ on a home solar system with battery battery backup???? Bottom line, at the end of the day you'll need something that makes economical sense and works; otherwise buy a good used BEV for around $16K I believe that we're closer to solid state batteries, you know that thing that's always only 2-years away. That would hop over this endeavor.
No, it is simply an option available for those that do. Solar is becoming common and cheap sodium batteries are becoming realistic. I've been supporting Prius for over 25 years now. It's easy to see the potential for that type of adoption over time. Home ownership spans decades. We'll see that eventually.
