Less does not mean worse, or as in the Audi was justified for a low charge


The maximum charging current, which support electric cars ?Audi e-tron and e-tron Sportback in top versions 55 limited to 150 kilowatts. This is less than some competitors. So, the newest Tesla V3 supercharger give 250 kilowatt, and Porsche are threatening that they Taycan can be charged with a current capacity of 350 kilowatts.

Like not wanting to look backward, Audi has issued a press release in which he tried to prove that their machine actually charged faster than the competition.


The fact that the battery is not always ready to accept a powerful charging current. The chemical processes that occur when charging the battery, lead to heat, causing the electronics limit the power and charging time is increasing.

Audi deliberately limited the power charging 150 kW, as found that a lot of power soon leads to overheating. In the end, the battery of the e-tron 55 is capable of charging from 5% to 70% of the current maximum power, and then power begins to decline.

On a full charge with a minimum of 5% to 100% e-tron takes only 45 minutes. However, in the Audi I emphasize that this is only possible under perfect weather conditions. Recall that Li-ion batteries like exactly the same environment temperature, and people. In the heat or cold they do not behave so ideally.


For comparison the graph of the charge “one of the competitors” which we thought was similar to the chart of Tesla. There peak power up to 200 kilowatts, but when 15% of battery capacity falls below 150 kilowatts, resulting in a full charge takes 45 minutes and an hour.

It is worth noting that the Tesla Model X, which is a direct competitor to the Audi e-tron, the useful capacity of the battery is 100 kilowatt hours, while the German cars only 86.5 kilowatt-hours. So if a competitor on the chart really means the Model X, the extra 15 minutes it compensates for the additional 13.5 kilowatt-hours.

Also I suggest you see the review of the Tesla Model X from the team InfoCar.ua:
