The public charging points in Amsterdam are dynamically / realtime configured based on the amount of energy the local grid can deliver. The 18:00 to 21:00 time frame is standard but it can be changed if necessary. And more places are going to follow simply because it is necessary. --- End quote --- And that's fine. Most public AC charging is opportunity based. Charging while visiting the shops or eating at a restaurant. --- End quote --- No. Not in Amsterdam where people have no private parking space at all. |

Mining and processing the materials isn't happening by itself and the energy required will need to be generated as well. Well to wheel analysis show an EV has quite a large CO2 footprint to produce. --- End quote --- * You're moving the goal posts. That was not the OP's question. * Various studies have been done on this subject, of course. I remember one by TNO (an independent research institute in the Netherlands) and the conclusion was that a battery EV had a much lower CO2 footprint during its lifecycle. It was 4 or 5 years ago, so by now it should be even better. --- End quote --- That depends entirely on how much you drive with your EV. Various well to wheel studies show you need to drive between 50k km and 225k km to break even with an EV compared to similar sized cars. The simple conclusion is that an EV isn't reducing CO2 emissions straight away. And it isn't moving goal posts entirely. EVs need to be built at some point and that does take energy as well. Apples and oranges both grow on trees. |

Those will not be throttled because they are generally (at least >50kW units) connected directly to the local high voltage grid (11~33kV) which has huge excess capacity inside towns and cities. --- End quote --- They may not be throttled by the grid but they will be throttled by Tesla. I remember seeing an article Tesla said rapid charger abusers will be banned from rapid chargers. |
