I have been reading about Tesla's turbo charging stations. From what I understand they charge with ac and dc current which I assume is having charged batteries send their energy into the batteries inside the car along with a charger. Is this something that can be done for small packs like we use?
Turbo chargers?

There is likely a detail I don't know or understand, perhaps there may be even an exaggeration piece of information in the mix of what I understand. a123 and lipo packs today can be charged very quickly with an RC charger, you can do this now, yourself. The differences are availability and cost. You won't find a small RC charger with your leads setup at a gas station or any other place other than your home. Of course, the infrastructure and components for a small RC charger capable of quickly charging our 1-4kwh packs on ebikes or whatever were using is substantially cheaper than the stuff they will use to charge a very large battery that quickly.
You might be interested to learn that DC current has a polarity, positive or negative which relates simply to the direction of the flow of current. Maybe I am mistaken, but I don't think you can use both AC and DC at the same time over the same wires because AC is DC with it's polarity flipping back and forth rapidly. If you were using DC, you would only be using DC.

They're called Supercharge stations not Turbo charge.
Ah yes, supercharging stations. Tesla will call them supercharging stations, I will call them turbocharging stations. lol.
If you put a full battery cell in parallel to another drained cell it will quickly send it's power to the drained battery. I assume just having the charged battery attached to the drained will act as a initial charge then just hook a charger up. One would think that full battery would quickly bring a drained battery to half capacity, but if you can continue to send power from the full battery to the drained until it is drained would require some kind of equipment. Along with a charger charging the cells at the max c rating, or a rating that would safely charge along with the supercharging batteries, would be an extremely fast charge.
Just curious if anyone else has done this.

no idea how there system works...
but is this for your bike ?
you can easily build a multiple kw charger for your battery using power supplies...
check out dr.bass's charger for his zero bike... http://endless-sphere.com/forums/viewtopic.php?f=14&t=52560&hilit=dr+bass+charger
what kind of cells/pack are you using ?

It looks like they're supplementing the AC power that they can pull from the grid with local DC storage, likely in batteries. The thing is batteries are charged with DC; that DC can come from other batteries (DC) or from a AC/DC converter. It is conceivable Tesla build a charger that can pull from both AC and DC sources to feed DC to the batteries in the car, they'd just need a smarter than average controller for the charger and/or BMS.
My 2 cents is they'd only do that in order to (for example) supply 120kW of DC power to charge the battery while being limited on the AC side to 50kW: they could charge @50kW their local reserve and whenever a car shows up they can pull 50kW from the grid and 70 from the local batteries. Generally industrial clients like Tesla pay as a function of power (kW rating) and energy consumed, so it make sense they'd minimize the AC power needed.
