Is it possible to use a portable power station with a 240 volt output to “fast-charge,” or at the very least, “4-8 hour charge” an electronic vehicle? Renter with no access to outlets near parked car. Want to charge the power station in home, then place inside vehicle, crack/open window, then feed cord to EV plug? Possible? Safe? Grounding needed?
My truck is currently averaging a tiny bit less than 2 miles per kWh. That means a 1kwh portable power station will give me a whopping 2 miles of range. Quick search for portable power stations it seems they won’t be very portable once they have large capacity. I found a 3600 watt portable station that’s 100 lbs, that doesn’t seem ideal to lug around. Plus if I’m averaging 2 mi/kWh, 3.6 kWh station will only give me 7 miles of range, assuming I can get all of the 3600 watts into my truck without any loss, which isn’t likely. $3,000 for this big portable station, expandable to 25 kWh which is my math is correct I’ll need to buy 6 more of these, the extra battery stations are $2000 which means I’ll need to pay $12,000 plus the main battery station of $3000, so $15,000 to get me 25 kWh. My truck battery pack is 98kwh, let’s say 100 kWh for easy math. This means $15,000 will get me only a 25% charge.
