Battery Breakthrough: Researchers Claim 70% Charge In 2 Minutes, 20-Year Life
New submitter chaosdivine69 writes: According to Scientists at Nanyang Technology University (NTU), they have developed ultra-fast charging batteries that can be recharged up to 70 per cent in only two minutes and have a 20-year lifespan (10,000 charges). The impact of this is potentially a game changer for a lot of industries reliant on lithium ion batteries. In the car industry, for example, consumers would save on costs for battery replacement and manufacturers would save on material construction (the researchers are using a nanotube structure of Titanium dioxide, which is an abundant, cheap, and safe material found in soil). Titanium dioxide is commonly used as a food additive or in sunscreen lotions to absorb harmful ultraviolet rays. It is believed that charging an electric car can be done in as little as 5 minutes, making it comparable to filling up a tank of gasoline.
Even if it did have enough capacity, it would take a 2 MW power supply to charge a 100 kW battery in five minutes, assuming there were no losses. A “gas station” that could “fill” five electric cars simultaneously would have to have a 10 MW grid connection. I don’t see that happening anytime soon.
A sufficiently advanced simulation is indistinguishable from reality.
Do you mean a 100kW/hr battery? There is no such thing as a 100kW battery. Idiot.
There is no such thing as 100kW/hr battery. There is a 100kWh battery.
If you are going to call people idiots, it's best not to be one.
USA electricity pricing is 8 - 17 cents / kWh (source: https://en.wikipedia.org/wiki/...). So let's say $0.2 per kWh
10MW = 10,000 kW. So if you were using the full 10MW connection that would cost $2000 per hour. I'm sure if you are using that much you get a special rate.
From a quick search I found this PDF: https://www.ergon.com.au/__dat...
For that particular 26500m^2 shopping centre their energy usage was 4000 kVA, which is 4MW. There are at least 9 shopping centres in Australia that are 5x larger than that in terms of m^2.
So yes, there definitely are connections of that magnitude delivering continuous power. And they are not all that uncommon.
This entire thread is full of jackasses computing the peak power draw and saying retarded things like "does it come with it's own fusion reactor?".
1. It's not a big deal to supply constant MWs to a relatively small number of charging stations along interstates. Next time you're driving along a highway look up slightly and notice the power wires carrying hundreds of MW's right next to you.
2. You don't have to size the power grid connection to cover peak demand, capacitors and batteries located at the refilling station are good at averaging out the peaks so that you just have to worry about some windowed average demand--and average demand is just not that stressful. Think of it this way, gas stations would also run out of gasoline quickly if they were refilling 8 cars at a time every 5 minutes for the entire day. OMG is the gas station right next to a refinery?!?
3. The vast majority of miles driven are daily commuting miles, which will be covered by low & slow charging at home.
4. Tesla basically does this *already* with their supercharger network. Why is it so hard to grasp this concept?
