T8 Owners, I had a dream...

Seti · May 16, 2017

That one day we will have a battery bank ala cellphones one that will compress and store massive power enabling us to plug it in to recharge our Hybrid batteries to 50% in 30mins.

In that dream, the little storage under the boot was used to pack up a few such banks, and for over 6months, I never ever had to visit the gas station again. I woke up and and realised it's still the deep of the night, but soon and very soon, it shall be day and the dream shall be a reality and it will be good.

And all those who wish to see this dream come to pass join me and say "AMEN".

C'mon Elon Musk! Develop this Hybrid battery bank ASAP please

He really already has. Tesla Supercharger stations can do pretty much exactly that with the models they're currently producing. Tesla and others are also working on competing high speed, fast charging DC stations that will be able to charge 200 miles in under ten minutes as I recall.

Are they portable battery banks like cellphone's? Or are you referring to fixed ones? My wish is to have portable and relatively flatter battery banks storing up high charge that we can then whip out and plug in for that battery power boost.

Edit: The dream was about having one similar to this cellphone example:

One day, and hopefully in my T8's lifetime, there will be to battery technology the equivalent of Moore's Law to computer chips

What the OP wants is another bigger battery that we keep in the trunk to charge the battery in the "transmission tunnel". Maybe a capacitor bank that can charge the battery that can then be used for electric drive with the battery acting as a buffer between the quick charge/discharge of the capacitor and the modest needs of electric drive.

Maybe let's crowd source funding and invest in such battery technology. Who knows.... SwedeSpeed Forumisters becoming $ gazillionaires

If you're going to charge it and carry it, why not just have more in the car to begin with?

Or are we imagining a 3rd party battery to battery transfer device? That's a lot of weight to be lugging around...

I just wish that our batteries have the capability to fast charge like the Tesla's and future EV vehicles. I mean fully charge in 10 mins. That would be ideal.

phillipu · May 17, 2017

It would be nice especially considering how small the batteries are. If you're in an area with lots of chargers you could really extend that EV range quite a bit.

For me, I want a true 50-mile range plug-in or a full EV with ubiquitous fast charging. Since the charging networks to support my latter option aren't quite built out yet, I'll stick to the plug-ins for now. I do just enough trips to areas that are far enough from established charging networks or power at all that a short range EV is simply not an option for me and a long range EV that takes much more time than a typical gas station fill up is just too inconvenient for my current family situation.

Kighter · May 17, 2017

Fast charging is still limited. The battery chemistry is altered and the capacity is significantly reduced. So rather than let that happen, Teslas will prevent additional fast charging of certain types - FOR THE REMAINING LIFE OF THE VEHICLE.

Yes these are all great ideas, but some of this technology does not currently exist. You can be sure Elan is working on it.

I've been dreaming about this. I'm totally impressed and surprised that it's first introduced in a Hyundai and not in a premium vehicle given the cost of going LiOn for the starting battery. Surely Volvo and European OEM can come up with a better integrated solution. Even so, this manual solution should be the base expectation given the thought and sophistication of systems in a new XC90 T8.

Thanks for this. With this, I'm now more confident that soon and very soon, we're going to see a portable Hybrid Battery booster/ charger, small enough not to take up too much space, but effective enough to let us have a couple of them in the boot and recharge our batteries to extend battery range to 150KM. That would then delivery the factory's claimed 2L/100KM range. Shoudl that happen, the T8 will be the best and efficient long distance cruiser.

I can't wait to see the dream coming to pass

A few things: (Forgive the pedantry--energy vs power is something most people struggle with as they are not familiar with using the proper units, and clarity helps us all.)
-Watts measure power. Power is measured on an instantaneous basis.
-Watt-hours measure energy. Energy is a measure of power over time. Therefore,
-Battery capacity in EVs/PHEVs is measured in kWh (or alternately amp-hours). *Not* kW. In rpmccormick's post above, he means he'd need a 40 kWh battery, not a 40 kW battery. The T8 currently has a 9.2 kWh battery, of which around 8 are accessible to the driver. Referring to capacity in kW would be like referring to your fuel tank in horsepower.
-Motor output is measured in kW. For example, the T8 raises the T6's HP output by 84. Thus the net power increase is approximately 64 kW. The actual # is probably slightly different due to the interaction b/t the electric motor and ICE, but it should be 60ish kW.

Also, 90 lb for the T8 battery? Ha! Try 550 lb.

Re: gasoline being an efficient form of energy storage--true. One gallon of gasoline holds about 33 kWh of energy. However, the overwhelming majority of that energy is wasted. The average tank-to-wheel efficiency of a gasoline vehicle is in the teens to mid-twenties. Measure well to wheel and it's even worse. Here's a Wait But Why-level overview (Tesla-focused, but applicable to all who are interested in EVs/PHEVs), and comparison b/t gasoline and electric.

On-topic with the original point: Teslas already charge at over 100 kW and can get 150 miles added in 30 minutes. That's pretty good, but in the next 12 months we'll see much better. ChargePoint has an EVSE capable of 400 kW charging, though there are not yet any vehicles that can take that level of power. Musk teased that the next revision of the Supercharger (likely to hit after Model 3 starts shipping) will do more than 350 kW. Once we get 300+ kW charging with reasonable availability, waiting around to charge is effectively eliminated as a problem for passenger vehicles.

Thank you Zaxxon for the clarification.
