Portable battery to charge Prime available?

If there was it would weigh several hundred pounds and be the size of a large suitcase.

 

... but it could have motorized wheels to help you get it outside.

 

There have been several companies that have developed "portable charging stations" for EV use. One company was promoting it as a quick charge for a tow truck to carry instead of jerrycans of gasoline.

The down side of using a battery pack to charge your prime is that there are conversion losses each time that you charge or discharge a battery. Arranging for a long extension cord is much more practical and better for the environment.

 

generator?

 

what we need is a robotic charger that you can call on an app

 

Given the cost and hassle involved, maybe just using charge mode doesn't seem so bad?

 

have you tried one of those jump packs?

 

Here you go: Blink Mobile EV Charging Station : Blink Charging

 

You can charge it with your gas engine sometimes or just not worry about it. A normal hybrid Prius might serve your situation better, but just charge when you get a chance and don't sweat it.

 

I have a jump pack that holds 29.6 watt hours.

If we were able to use that to charge the Prime's traction battery, then at the Prime's published 259 watt hours per mile, it would move the car nearly 604 feet.

Which, thinking about it, is really kind of impressive.

 

That's simply a 9kw gasoline powered generator. It would work, but most generators create more pollution per killowatt than a car does. That kind of cancels out the who reason for going to electric cars.

 

I agree. I believe it is marketed as a commercial product for a roadside assistant for stranded BEVs or as a supplement to blink networked chargers where the electric grid is not available. I would not think there is a good use case for residential applications. That being said, the spec of this gas generator must be really good. It states "The mobile plug-in charging unit can deliver up to 1 mile of charge per minute." Obviously not for PP though.

 

With a level 2 charger we get around 1 mile per 5.2 minutes of charge on a Prius Prime. (If my math is right)

 

I got the same 5 min 12 sec per EV mile using the EPA rated 25 EV miles and 2 hours 10 minutes charging time empty to full. Newer Primes have been reporting a flat 2 hour L2 charge time in some cases with would bring the time to 4 min 48 sec / EV mile. It's all over the place for owners who get both less and more than EPA rated 25 EV miles. I've seen one new Chargepoint install finish up a full charge on my 2017 in a bit less than 2 hours, like an hour and 50 minutes. The standard works well in this case as long as everyone is on the same page.

 

Considering the fact CHG mode can fill the traction battery at 1%/min at stationary idling (1mile/4min) or 2%/min while driving (1mile/2min), using CHG mode on PP is probably the fastest way to charge. And likely more efficient and cleaner than using a gas generator.

 

I think you understand it perfectly.
I think that CHG mode is only useful in a VERY limited number of situations.
I have often wondered why it is even there.
Wonder what the owners manual says about it ?
