laladenett Posted August 28, 2020 at 07:17 PM Report Share Posted August 28, 2020 at 07:17 PM Hello all, I just became a owner of a 2017 Ford Fusion Energi SE. I love the charging feature. However I live in a sketchy area and don't like leaving my vehicle to charge. I also do not have a parking garage with an outlet. I have parking space in a multi level parking garage. Would if be ok if I brought the portable DieHard 71688 1150 Peak Amp 12V Jump Starter with USB/12V Portable Power Ports and 100PSI Air Compressor and fully charged it and proceeded to plug the charger from the Ford Fusion in it to charge the vehicle? Is there any other recommendations? Quote Link to comment Share on other sites More sharing options...
murphy Posted August 28, 2020 at 11:35 PM Report Share Posted August 28, 2020 at 11:35 PM It delivers 400 watts. The battery is 5.6 kWH. 5600 watt hours divided by 400 watts is 14 hours. I guarantee the battery in the jump starter will not deliver 400 watts for 14 hours. The DC to AC to DC conversion losses would make it very inefficient also. Look for public chargers that can charge the car at 240 volts I charge mine at 240 volts and it takes slightly over 2 hours to charge the battery. Search the internet for Chargepoint, Green Lots, or just EV battery charging to see if there is anything close to you. laladenett 1 Quote Link to comment Share on other sites More sharing options...
jsamp Posted August 29, 2020 at 01:12 AM Report Share Posted August 29, 2020 at 01:12 AM (edited) Portable batteries will not charge the Energi HV battery.. not even close. It would have to be able to deliver 1500W continuously to charge the car. It'd have to be a HUGE battery to pull that off in one go, or you'd have to go back and forth numerous times to recharge the portable battery. Best thing I can think of is scour your parking garage for any 120V outlets that may be hidden somewhere that you can 'use'. I'd get a lock for the plug (J1772) that goes into the car if you are worried about theft. Other options... find local stores that have free or affordable charging that you can use while patronizing those establishments. There's a supermarket in my area with two Volta free charging stations (voltacharging.com). If you know when to go there, one is often available.

laladenett Posted August 29, 2020 at 02:28 AM Author Report Share Posted August 29, 2020 at 02:28 AM Thank you both! I did not have my hopes up that it would work but I thought I would ask. Have a great weekend. Quote Link to comment Share on other sites More sharing options...

I was so paranoid that I got a portable generator, wired it for 240 volts and kept it in the car! The gasoline fumes from the generator stunk up the car and even when I used it, took like a hour to add 6 miles of range. So even with the 3/4 gallon of gas energy it did not help. Sold the car and kept the generator! The physics doesn't work, a thousand pound lithium high energy density battery pack being charged by a light handheld device defies physics.

stevon Posted September 30, 2020 at 06:13 AM Report Share Posted September 30, 2020 at 06:13 AM (edited) Laldenett, Besides the car Hybrid battery is 300 to 400 volts DC! a 12 volt "jump pack" only charges the 12 volt lead acid engine starting battery. If you used an inverter to 120 volt, then to an EVSE, then the car's internal inverter/charger to 300-400 volt to charge the hybrid battery pack you can see the losses and how futil such a design would be.

Stephen The weight of the generator has little to do with it. It is more that 3/4 gallon of gas equals ~25kWh theoretically, minus the losses. A small engine like that would at best give you 20% efficiency leaving you only 5kWh. Then factor in EVSE and charging losses and you wind up with far less than that. Plus the fact that the generator can only last so long on 3/4 gallon to begin with. jj2me 1 Quote Link to comment Share on other sites More sharing options...
