This is the summary of several charge curves of different Tesla models. It is important to emphasize that it comes from America, where probably the supply of charging stations is even stronger. In Europe there are restrictions, e.g. that each two charging stations are combined to 145 kW. We have already reported on the overall management of charging stations and the possible cuts if more vehicles are involved.

Basically, this is a single vehicle that is connected to a Tesla Supercharger for 90 minutes. You see above the energy flow and below the increase in energy per unit of time. It takes a while for the procedure to get underway. Then we consider the first 5 minutes of pure loading time.

The charging power increases in the time from about 55 to 110 kW, making an average of 82.5 kW. 5 minutes is the 20th part of an hour, so over 4.1 kWh have arrived. From 5 to 24 minutes, the charging power drops to 105 kW. The average is 107.5 kW for 19 parts of 60 minutes: 34 kWh. That makes good 38 kWh more capacity in the battery now.

From 24 to 90 minutes, the charging power drops from 105 to 5 kW. From a purely mathematical point of view, this would be 50 kW in 66 minutes, ie 45 kWh. You see that the good 83 kWh in the end are not quite reached, of course, because here is no straight, but a little down bent curve is present. It has just been a total less charging power.

Overall, so fit the two curves to each other. Incidentally, both have been recorded by the vehicle electronics, so can not take into account the output from the charging station power. Possible losses during the charging process stay out of here.

So loading does not happen constantly over time. It forms an important part of the driving time in the electric car. In this example, it would have seemed best to stop after 24 minutes and settle for 34 kWh. But probably no computer program in the world can calculate the best strategy between charging and driving time or speed.

The electric car behaves differently than the combustion engine. The latter wins the long haul with a powerful engine and streamlined bodywork. Previous world record attempts with electric cars have shown that not the strongest model with 100 kWh and 250 km/h top speed, but rather the Model 3 with 'only' 75 kWh and 233 km/h wins.

At the moment (2018) the receive a good 2,600 km in 24 hours, probably almost only on German highways possible, because partly without speed limit. Lonesome winners are the Teslas, because with them the combination of performance, loading capacity and loading speed is currently unattained. Typically American here that the relatively higher consumption could be compensated.

They are on a good way. No, you should not take a vehicle with an internal combustion engine to scale, because a cross section of 110 km/h with three people over 24 hours creates probably every new car from this group. We will have to lose some freedom for the sake of the environment. It is only a pity that the manufacturers of electric cars believes that the potential buyers do not have to admit the disadvantages. But people know exactly what's going on.
