Battery charge in 5 minutes at 150 kw

Hello,
You do not give any details about the battery.
What kind of battery?
What capacity?
The mentioned 5 minutes and 150 kW, don't tell anything about the battery at all.
Have a look at the Battery University, if you want to know more about batteries:

Perhaps it is the battery used at this location – by my calculation charging at 150kW would take more than 3 days to fully charge (from a flat battery).

The nearest thing I can think of that can charge at that sort of power level is a pumped storage system such as this one at Dinorwig in North Wales. (Although this is not a battery in the normal sense.)

Why from my local sub station of course.Where are you going to get 150kW of power?
They have millions of watts just sitting there for the taking. Ron
Change the k to an m and I'll believe you.I generate 150kw on an afternoon ride on my bicycle
Change the k to an m and I'll believe you.
Now comer on I will admit I can't get up into the mega watts.
Oh that is a small m.
150KW is the about the power level electric cars charge at on fast charge ..."Tesla Supercharging stations charge at 120 kW per car. That is up to 16 times as fast as public charging stations; they take about 20 minutes to charge to 50%, 40 minutes to charge to 80%, and 75 minutes to 100%."
fast charging reduces battery life .... car manufacturers will be desperate to speed up charging rates , so we can assume it's not possible to go quicker than 40 mins full charge unless the batteries have an elaborate cooling system ...

.... so that they can sting you for replacement batteries at frequent intervals

Hi,
Finally a voice of reason
One of the Tesla's has a 100kWh battery.
However, referring to the first post, i dont think there is any battery that can be charged in 5 minutes to full capacity UNLESS it is specially designed. There are specially designed batteries that can take an extremely fast charge, but not the common battery like the normal 18650.
Maybe they make a special 18650? Doesnt seem likely but who knows. The typical run of the mill would get too hot though because of the internal resistance and the fact that the heat dissipation has not been taken into account except for the normal charger rates. There are some batteries that can take higher current that are somewhat run of the mill, but they are advertised as such and have charge currents that are much higher than typical. They still take at least an hour though for a full charge.
The ones make for super fast charge are specially designed and probably expensive and aimed at the EV market.
Also, what does it take to generate 120kW even. Power is voltage times current assuming no reactive components, so if we start with 120v that means we need 100 amps to generate 120kW, ideally. Many houses have just 100 amp service, meaning that the maximum input current to the whole house is just 100 amps. So for a residence like that, the entire power available for the whole house would have to be used to charge that battery, for one full hour. That means nothing else could be used for that hour.
To get that down to 1/2 hour, we'd need to be able to draw 200 amps. That would charge this battery in 30 minutes. Some residences have 200 amp service, but again it would use the entire available power for just that one thing.
To get that down to 10 minutes we'd need 600 amps. That starts to get into the industrial area now.
To get that down to 5 minutes, we'd need 1200 amps. That's industrial.
Even at 240 volts that's still 600 amps, and that's a lot of current that normal residences wont have.
We can also ask the long term question ... how the heck is the grid going to be able to handle this once electric cars becomes widespread. We already have problems in this area in the USA. For a block of 20 houses with 200 amp service, that's 4000 amps total, and what happens if 10 of those are charging their car at the same time. At 240v that's 6000 amps. What is the whole grid going to have to be rewired to service electric cars.

I just read that even the special design batteries dont charge fully in 5 minutes.

MrAl, are we sure that is correct? 120 kW is 120,000 watts right so 120000 Watts / 120 Volts = 1,000 Amps. Am I missing something in there?
Ron
A little less than that. These chargers charge at 240V so that would be 500 amps.
But I think they are saying the battery is 120kw (or 150Kw) . I have not found the figures on that but again anyone that needs to ask how to charge a 150kw battery should not be messing with charging a 150kw battery.

These guys are working on it, maybe ping this company and see if they're willing to talk to you:
