How fast does the car really charge??

The VW ID.3, which was launched just a few months ago offers a strong charging performance. InsideEVs USA reported on the DC fast charging capacity of the Pro version (58 kWh net / 62 kWh gross) based on the test results from the European charging network provider Fastned.
We will analyze these results in more detail here. We want to find the optimal state of charge (SOC) for plugging in and out and see how quickly the car recharges range.
Decrease in charging power with increasing SOC
The ID.3 Pro with 58 kWh of usable battery capacity has a pretty good-looking charging curve. The curve looks a little different from the one published in September as it covers a wider range of the state of charge. In addition, the tested ID.3 may now have newer software. The curve could also change slightly due to the battery warming (when starting at a lower SOC).
The ID.3 Pro reaches its maximum charging power of around 100 kW fairly quickly, which corresponds to the value specified by VW – only the versions with a 77 kWh battery achieve 125 kW. This value remains constant up to a charge level of around 30 percent. Then the power gradually drops to around 50 kW at around 70 percent SOC, remains there until around 81 percent SOC and then continues to decrease. At 94 percent, only just under 25 kW are charged.
- Maximum charging power: approx. 100 kW
- C-rate (power compared to total net battery capacity): 1.6C to 1.7C
Average charging power at 20-80%
Now let’s take a look at the average charging power during the charging process from a starting SOC to an ending SOC. The average power for the common charging range (from 20 to 80 percent SOC) is around 70 kW (marked in the diagram):
How fast is the range recharged??
The ID.3 Pro has a WLTP range of 420 km and 58 kWh of available battery capacity. This results in a power consumption of 138 Wh / km. The charging losses are not taken into account.
The following diagram shows how many kilometers of range are recharged per minute, and at what charge level.
In general, results above 5 km / min are considered ok; then it takes 20 minutes to recharge 100 km range. At 10 km / min, 100 km are recharged in 10 minutes.
Similar to the average charging power, we now determine the average speed when recharging the range in km / minute from a start SOC to an end SOC. The average for the usual charging range (20 to 80%) is around 8.4 km / min.
If you are interested in the calculation method: We have calculated the power consumption above at 138 Wh / km; that is 8,280 Wmin / km. From 20 to 80 percent SOC, an average of 70 kW is charged (see above), i.e. 70,000 W. If we divide the 70,000 W by the 7,680 Wmin / km, the above-mentioned 8.4 km / min result.
