ELI5: " Why can't we just plug 10 chargers into an electric car and charge it 10x faster?

ELI5:   Why can't we put 10 different batteries into an elecric car and charge them individually so that the charging could be 10 times faster? Could be any electrical device, such as smartphones, etc.

Edit: I feel like a few people didn't get the point. I know there are special "superchargers" that charge faster (while ruining the battery a bit). Think of it this way: charging one electric car takes as much time as charging 10 electric cars. So why can't we put 10 separate batteries in a car and charge them with 10 separate chargers?

For a car charger the limitation for home use the limitation is not the car but the power that a outlet can deliver or the electrical connection to the house. The car or the battery in the car is not the limiting factor.  

A Tesla supercharges station have 480 DC charger that can deliver 250kW  That is 250000/480=520A. 

In the US where there are 220V to the house you would need 1136A fot the same power. A outlet for a electrical oven that would be what is relative common and use a lot of power max out at 60A or 1/19 of what is need for a Tesla supercharges 

I Europe where 3 phase to homes at 400V is not uncommon you would ned 250000/400/3=208 Amp per phase.  For a very large home in a cold environment that is heated by electricity you might have 3 phase and 35A fuse

So for residential charger it is not the car or the charger that you might need  that is the liming factor but the connection to the power grid.

Because 3 phase and higher voltage is common in Europe Teslas sold here have charging electrons that support the plugged in direct  to the car.

A Tesla model X with the largest battery have 100 kWh  and it take 100/250=0.4 hours = 24 minutes to charge them full if it is 100% efficient. At this point it is the cooling system of the batteries that is the liming factor. 

So charging speed is in most case limited by the power grid and not the car and you need expensive electrical system and chargers before it is the car that is the liming factor.
