Supercharger enhancement/upgrade

Supercharger enhancement/upgrade

I'm sure this has already been answered/thought of but what if the battery was "broken, segregated, whatever you'd like to call it", into four quadrants and instead of one flow of energy from a single connector (with twin chargers on board), what if in the future we had drivers drive up to a Supercharger station and there would be four connectors that come up out of the ground to deliver a charge to the battery from four different connections? Would it make the car charge 4x as fast? I would think you'd need additional on board chargers but the cost of not battery swapping (inventory holding costs), and if the physics/science behind pushing +120kW to the same battery but specifying it into four different quadrants via 4 different charging ports, I would think that a solid charge would take closer to 7-8 minutes instead of 30 minutes.

In my mind, if you split up a water tank into four quadrants and fill them up with the same FLOW and PRESSURE, each having their own individual faucets so to say, you’d theoretically be able to top off quicker than a single tank with the same flow and pressure from one faucet.

Thoughts??

The supercharger already blasts all the cells at once.

The more cells there are to endure the "blasting", the more "flow" the pack can handle.

First of all, the on board "chargers" are actually AC to DC converters and as such have nothing to do with Supercharging because Supercharging literally moves those AC to DC converters out of the car and dumps DC directly to the battery.

Second, as DTsea stated, the software managing the flow of electrons into the pack is already distributing the power evenly across all 7000+ cells.

Cheers!

Convert current effect, the following car exchange electric current will be deposited with sufficient power to drive the uniform flow, and that is to say, hard to withstand hardware conditions.

Batteries have a certain C rate, a rate of charge/discharge. Different chemistries have different rates. The total amp hour the battery has times the C rate is the amount of amps the battery can charge or discharge. I think the Tesla batteries are 2C (for charging). At 1C a battery will charge in an hour. At 2C half an hour, 3C 20 min, 4C 15 min. C rate divided by 60 (minutes in an hour) equals charge time.

Some lipo batteries for RC use have C rates as high as 90c for discharge, and 15c for charging! That is a 4 minute charge time, if supplied with enough power! It also means the battery can completely discharge in 45 seconds!

Dividing the battery into smaller sections makes no difference, unless the source of the power is too small. The Tesla batteries are most likely good for up to 170kWh for the 85kWh pack, and 120kWh for the 60kWh pack. Except maybe the A battery, they may be only good for 1C therefore 90kWh is the limit.

I just had to ask, I figured it would be something to do with the physics of charging batteries whether you charged 4 quadrants of the batter each having a supercharger connection or you stuck to the current method of charging. I wonder if future technology would allow better charging methods? Has anyone heard of anything aside from the slightly higher supercharger station in Germany??

There's a long thread on multiple feeds. Use Volkerize.com to find it if you want. Short version: makes no difference, and expensive to implement.
