Volkswagen ID.3: the charging and travel times of our Supertest

The Volkswagen ID.3 has no more secrets for you in terms of autonomy after the first part of the Supertest. It remains to be seen how it behaves in front of fast charging stations and on long trips with this second part.

To clarify electric cars and their consumption, we decided to carry out full-size tests, making each model studied travel almost 2,000 km. An opportunity to measure the range on long journeys on the motorway, but also the mixed consumption and charging power at fast terminals. For this, we implement a strict protocol for each car.

Volkswagen ID.3 charging curves: a full “useful” in 33 minutes

In addition to the slow charging chapter, where the Volkswagen cannot compete with the Megane e-Tech, it has a direct current fast charging power of 120 kW. That’s just 10 kW less than on Renault’s datasheet. According to the brochure, the recharge time from 5 to 80% is 35 minutes. In fact, the ID.3 delivers on all its promises and more: plugged in from 5%, the compact quickly rose to a power of 131 kW ! This is the most we could observe during the test, in a Fastned terminal and without having activated the battery preheat.

Then follows a loading curve with a profile modeled on the other curves we observed, although with higher power values ​​of 2 kW at most in the intermediate SoCs. The peak power unfortunately doesn’t last, but the high powers hold up to 20% before forming a first step. It is from 25% that the curves of our full refills meet. However, despite the slightly lower powers, recharge times are similar to the minute.

In the end, 10-80% recharging of the Volkswagen ID.3 requires 33 minutes very accurately. When cold, with a peak of 107 kW at 10%, the same type of charging takes only 1’30” longer. Not enough to change a driver’s life on the long journey. Especially since it will be rare to fill up a fast charging station early in the morning before heading out. On top of that 70% charge, Volkswagen gained an average of 41.5 kWh according to the terminal display, or 40.6 kWh according to the strict rule of three taking into account the useful capacity of the battery. The difference is small.

The curve forms a final plateau between 70 and 80%. Also, it will take another 10 minutes to get to 90%. In total, the total time is just under 59 minutes to complete a 10-100%. Percentage hunting has its limits on the highway since, to go into detail, with the ID.3 almost 20% is lost over 43 km, of which 2% is consumed only when leaving the rest area.

Autonomy recovered: 157 km in 30 minutes

According to our measurements, the Volkswagen ID.3 has a total range of 243 km, or 170 km of useful range. In a fast terminal, it can thus recover 170 km of autonomy in 33 min. Always from a SoC of 10%, it will be possible to gain 97 km in 15 minutes on the way back, while it will take almost an hour to have a motorway range of 218 km.

Still in terms of autonomy, the screen is linear in its ads, but still a little optimistic. According to theoretical calculations, according to all our motorway readings, it is based on an average consumption of 21.7 kWh/100 km. In reality, this corresponds to a range difference of at most 10 km. Difference that decreases as battery charge decreases: there is a difference of 7 km at 20%, 3 km at 10% and 2 km at 7%. The SoC/autonomy ratio, therefore, seems to be quite reassuring.

Autonomy recovered/recharge time

How much do Volkswagen ID.3 refills cost?

Volkswagen has the advantage of being part of the consortium of manufacturers gathered around the Ionity charging network. With the compact, drivers can benefit from preferential rates through the We Charge ID badge, which gives access to more than 250,000 charging points in Europe. There are three formulas, with emphasis on the We Charge Plus offer of €9.99/month in the first year, after €17.49/month. In this case, the price at Ionity terminals drops to €0.30/min.

In other words, the 10-80% top-up costs just €9.99, i.e. a direct cost of €5.82/100 km. Very attractive for a motorway trip, especially considering the total price of €0.79/min, which would raise the bill to €26.07 (€15.34/100 km). But this case must be taken into account, as the badge provided by Volkswagen was not recognized at the Ionity station in Maison-Dieu.

In addition, the We Charge seal was not accepted on Fastned terminals. Fortunately, if we had a spare Chargemap badge, they also offer the possibility to pay directly by credit card. According to the information communicated by the terminal, the exercise represents a charge of 41.5 kWh, or €24.49, or a cost of €14.41/100 km.

For this trip on the A6 motorway in the south/north direction, we had to recharge three times for a net amount (excluding operator fees) of €45.41. That’s a total cost of €10.56/100km before our last stage (a distance of 430km). As usual, we do not calculate the cost price above 500 km, as it is the price of the last recharge to find the initial SoC that will determine the total cost.

Onboard route planner, ABRP and ChargeMap: ABRP in the lead (slowly)

Last exercise of this Volkswagen ID.3 Clean Car Supertest, the comparison of route planners. Available on the central screen, the German tram’s navigation is particularly pleasant. It takes the trouble to warn that the destination is out of range of the remaining autonomy and presents an isodistance map of the range of action.

From our starting point, he selects the A7 and A6 highways that serve as the base to reach the Porte d’Orléans in Paris, the finish line of our journey. With 80% of charge available, enough to reach the Fastned station at regulatory speeds, the planner, however, favors the Ionity terminals, necessarily and a Total station. In the end, he predicts three stops for 1h17 of recharging (total of 6h25 with travel times).

The A Better Route Planner app also likes the Ionity terminals, with a stop at three main stations on the route. However, having a better database with this vehicle, recharge times are quite close to reality, at the same time it makes us arrive at stations with 10% charge remaining (except for Taponas). In short, according to him, it takes 4h42 on the road and 51 minutes of recharge for a total of 5h33.

ChargeMap manages to reach the Fastned station in Saint-Ambreuil and the Ionity terminal in Maison-Dieu, but takes us through the Total station in the Couline area. Total operations: 47 minutes of charging and 4h20 on the road (total of 5h07). Again, within minutes the cooldowns are practically real. Minus the SoC predictions when arriving at the terminals. Proof of this is with the first forecast, where the ChargeMap system predicts a rate of 23% when arriving at the Fastned station.

In reality, we got there with 7% charge remaining. First fill to 70%: 27 minutes. Enough to earn just enough to get to the Maison-Dieu area, where we reach 12-70% in 25 minutes. Finally, last recharge at an Ionity terminal near Nemours with 11 minutes of immobilization.

In the end, our strategy modeled on that of the Renault Megane e-Tech examined a few days earlier the results in a trip of 4h22 and 1h03 of recharge for 500 km. Adding the time of evolutions in the areas, our journey represents 5h37. In the case of the Volkswagen ID.3, A Better Route Planner seems the closest to reality. ChargeMap isn’t far behind, but its slightly over-optimistic first estimate turned the charging time on its head. Otherwise, the SoC consumed/km traveled is the closest to what we actually observe. Certainly, this method of calculation is not very rigorous, but it is what speaks most to neophytes.

What is the Supertest?

Lovers of numbers and allergic to official sheets, Supertest, Automobile-Propre’s new test format, is made for you, gathering data collected during a test under real conditions and according to a transparent and accurate protocol. We will publish a new abstract article next Wednesday. allowing to compare the annotated values ​​of the tested models, which will make the entire value of the title.
