Today, There are many car manufacturers working on rechargeable systems for high-power electric cars, which should allow for much faster loading time in the future. These projects will be of great importance for the development of the electric car market in the coming years, as one of the points that slow down its growth is precisely the time of high load compared to thermal models.
At present, the brand that offers more power in a street electric car is Porsche than in its Taycan model (which will be available later this year) allow loads up to 350 kW power; or what's the same, to recover 80% of its autonomy in just 15 minutes (remember that its battery will be 95 kWh, which should be more than 500 km in real terms).
After Porsche we find Tesla, who recently discovered his V3 Superchargers, which are capable of reaching a power of about 250 kW, a figure that only Model 3 can currently use (models S and Model X fitted with the new generation Tesla engines are capable of reaching 200 kW, although it is expected that with the restart that both models will get access to large powers at the end of the year) .
However, Audi, the third brand with the highest load in an electric car (Your e-tron model is capable of reaching 150 kW) claims that the high power achieved by the Tesla model does not really mean anything, since this figure is maintained for a very limited period of time, is rapidly declining.
During the e-throne presentation in North America, Matthew Mostafaei, the manager of the e-throne and associated Audi cars in the US, showed the public's interest in comparing the charging rate of several electric models. According to Mostafai, Tesla can reach power over them; however, its load rate drastically decreases during the session.
For comparison, the Audi e-tron can remain over 140 kW for a long time (until it reaches about 80% autonomy), something due to the advanced cooling technology of their batteries, as well as the wide margins of the package (despite the 95 kWh capacity, the "lower" part of the battery has a reserve of 8% and a top 4%, which explains that when the truth is autonomy the model is "only" 417 km WLTP). This has positive consequences for faster loading and longer service life, as it has high limits, battery degradation will be lower than in other electric cars.
