You shall not rise, page-27

This just more of the same... Manufacturers LOVE to dance around in the grey area, never giving you any kind of definitive data. Just a whole heap of what ifs, and what we expect, this is no different.

No where in the article does it tell you from what SOC (state of charge) they are starting from, or what SOC they are finishing at.
So they might be starting with a SOC of 90% and going to 95% (relative), without any quantifiable measurement points it is just pie in the sky marketing guff.

They would love to have the uneducated public believe that they are going to take the battery from 0% to 100% in 10 minutes. But a battery pack should never get remotely close to 0% or it will kill the battery pack as dead as a maggot. All modern cars won't let you ever drain down that far. Same goes for charging to 100%

100% is not actually 100%, in a lot of cases when you charge the car to full, it is only charged to about 80 - 90% because fully charging the battery significantly shortens the battery life. So really a full charge in the real world might be from say 35% to 85% or half of the batteries capacity.

Also what a lot of manufactures like to slip in is something like a top up charge calling it a charge. Because you can put a reasonable amount of power in quickly, but once you start getting close to the full mark it has to throttle back the rate at which it feeds the pack or once again it will damage the pack or worse explode. So while you might be able to charge 40% in x amount of minutes what they don't tell you is that the next 10% is going to take 5 times x.

So if you want a full charge to go a long way, you are never going to do it in the crazy times they try to promote. Also majority of these claims are from laboratory testing where they guess at what the real world results might be, quite often they start making these outlandish claims and they haven't even built a working battery, let alone charged it.

All you have to do is look at the numbers to know what they are saying isn't possible. Take for example Tesla's biggest car battery which is 100 kWh or 100,000 Wh.

Let's say that we need to put in 50,000 Wh as reasonable flat to full charge. If you charge at the maximum a typical Australia GPO (General Purpose Outlet) which is 10A and 240v (Australian power is supposed to be 230v, but is often 240v) that means you can draw only 2400 watts before you start pushing the friendship with the wiring (remembering this is a sustained charge, so heat will build up).

Not factoring in charger losses, as no electrical appliance ever gives you 100% of what you put in. This will take over 20 hours, now lets get crazy, lets say we charge it at 10x that rate. We are now pumping in 24,000 watts to charge in 2 hours. Again let's 10x that 240,000 watts to charge in 12 minutes (1/10 of 120 minutes). What cables are they fitting to the car that can take 240,000 watts?

Granted my math is a bit crude, but you get my point. Most of these ridiculous claims exist only in peoples imaginations.
