EV general discussion

no surprise if you have basic physics - sounds like need a regulatory body to enforce honest product advertising.

Also looks like it is a pairing system, so 125kW only if the paired partner charger isn't in use? Like you say though, better than nothing

Ah yes, I had not spotted that, that really is cheeky calling it ultra rapid then. You'll be stuck at 125A / 50kw @ 400V if the other charger is in use. At least it will probably work as its:
A) not a tritium charger
B) actually maintained.
 
The 125kW chargers have two units in a pair and 4 power modules around 33kW each. So it will shift between the two as and when. So as you say peak will be 125kW with only a single car charging.
 
looking at BP pulse
.. so if you turn up at the charger first thing in the morning looking for your 20->80% maybe you get 100KW, but will the n'th customer.
“We have available two different
types of battery chargers - the Pulse 150, has a 196kw battery, which is more than three times the size of the battery used in the UK’s bestselling EV, the Tesla Model 3.

“It charges using 40kW input power. It trickle charges constantly, and can charge two cars at greater than 100kw at the same time.

“It’ll do more than 20 charges back-to-back-to-back… while continually recharging itself. Retailers would only need a low-power grid connection. The BP Pulse 120, produced by Freewire, takes as little as 20kW input power. One of good things about the battery chargers is that they’re not putting strain on the grid through drawing high-power, they’re taking a continuous low power feed and storing the power.”

This isn't for high traffic situations lads.

It'll be in Sticksville where you'll be lucky to get more than 5 cars charging a day for the forseeable future

Plus even if the battery is empty you'll get 40kW, which to be honest is about the average you'll be getting at a rapid anyway.
 
Battery pack buffering really isn’t ideal, it significantly increases the cost to deploy chargers and lowers the return on investment. I’d imagine that battery isn’t going to last very long is it is used back to pack on the daily.

But yeh, I imagine they will be deployed out in the sticks, however, I expect most forecourt’s are very power limited these days already and as such they’ll be looking to deploy these everywhere. Really they should be looking to deploy a minimum of 4 chargers, so really you need 120kw or more as a sustained power input.

It’s worth noting that Tesla has ‘mega packs’ deployed at South Mimms and has done for years. It still doesn’t stop the site being **** at peak times.

OEM warranty will typically be 10 years

The system tends to work down to 20kw for a double sided system so 40kw for 4 chargers

And you would do the sums and install the economic solution if a grid connection is available/cheap

Or it’s way cheaper than putting a decent grid feed in.

Don’t confuse your opinion with fact. Cheers
 
I ran some analysis of the total C02 outputs of my current EV, Polestar 2 and previous car, BMW 520d: build and use - interesting results. EV is less over the 3 year, 36k mile use period.

Yeah I think it’s for the remote forecourt’s really though. Good to offer a choice of products in my view! Look at leicester forest east

The cynical side of me thinks these will just start getting deployed where really a big fat grid connection should be being put in. That’s U.K. 101 right there, go cheap and probably not fit for purpose.

Uk 101 is people moaning about anything that’s trying to make progress

this is capitalism, even if meeting the needs of the many with 50Kw is going to provide better average throughput (guess it's going to say that)
... if I'm ready to pay for a premium guaranteed 150KW service then someone should meet that need, maybe I'll pay extra for a 100% green product too.

EV carbon manufacture costs have dropped from earlier discussion of 50 odd tonnes ?

On the media page of the Volkswagen Group you will find the latest news and contacts of our brands and companies, dates and publications.

The upcoming carbon border taxes should make such costs much clearer.
