loading and travel time of our Supertest

For this first racing style, a first, the MG ZS EV is designed to be more versatile. You can travel without worries, as we saw in the first part of your Supertest, but it is not the fastest. Explanations.

The MG ZS EV has become a perfectly modern and attractive SUV that is no longer ashamed of its European competitors. The different consumptions and autonomy that we have observed are rather correct, as long as it does not work for a long time at high speed. But this is what only a few users will probably do, but they will have to anticipate their movements.

MG ZS EV load curve: a full “useful” tank in 41 minutes

Equipped with a new battery, the MG ZS EV is now capable of storing a maximum power of 92 kW in direct current in the fast terminals. This puts it in a correct average of the category and allows it to officially claim a recharge time of 5 to 80% in 40 minutes.

In all our attempts to load, the SUV was never able to reach its advertised peak. Only a maximum of 90 kW was observed at a 35% SoC in a Fastned terminal (11 ° C at the time of measurement), after a drop where the power dropped to a minimum of 79 kW. Keeping your head above water up to 75%, the curve goes down considerably further. This goes from a power of 59 kW to 27 kW from 80%. This is where the vehicle should be disconnected, as the levels recorded afterwards are too low. At this terminal, we realized a 41 minute recharge time between 10 and 80% charge.

If the times were similar to Ionity, it was in a terminal of the Allego network where we recorded the best time, 37 minutes … virtually. Because if the MG ZS EV showed a nice curve (88 kW on average up to 50%, then a sawtooth drop of up to 80%), it presented some amazing load cuts. During this reload test, we recorded three outages, which extended the total downtime to 41 minutes, the time to restart the operation each time. Please note in this paragraph that the ZS has load cuts only on Allego terminals. We have not encountered any problems with other operators (apart from an impossible start in the Fastned terminal, resolved with a remote reboot). According to the manufacturer, it appears to be the result of a safety stop when the vehicle observes excessive variations in current.

In any case, it is useless to think about going further later as the power drops to an unacceptable level on the highway. From a power of almost 30 kW to 80%, the curve dropped sharply: 16 kW to 86%, 12 kW to 87%, 8 kW to 88%, to reach 6 kW of power at 90% load ! Having the last 15% requires a lot of patience: we have calculated 36 minutes to go from 80 to 95%. We reduce the times at this level, while the terminal already shows a power of 4 kW. Endless. And it will be difficult to derive a total recharge time, as the visualization of the remaining time was exceeded by his own estimates: he initially promised 55 minutes of immobilization to go up to 100%.

Typical recharge curve

Recovered range: 146 km in 30 minutes

According to our readings, the MG ZS EV has a total range of 266 km, or 186 km of useful range between 10 and 80% of the available load. At a fast charging station, you can recover this range in 40 minutes. This is almost equivalent 146 km of autonomy recovered in 30 minutes load pause. Note that the range display is based on previous consumption. However, according to our calculations, it would take almost a hundred miles before you could adjust the remaining range value according to the loading speed. Once calibrated on the highway, however, it will present a value quite close to reality, although a little more pessimistic, around 10% on average.

Recovered autonomy

How much do MG ZS EV spare parts cost?

“Car” is the answer that will come straight to your mind when you consider the reuse time. Mainly because MG does not benefit from any subscription or advantageous rate on Ionity terminals, apart from the operator’s public offer per subscription. With this hourly turnover of € 0.79 / min, it will be necessary to have a total amount of € 31.60. This costs € 16.98 / 100 km. In Fastned, the billing system is then more interesting as the MG ZS EV has gained, from 10 to 80%, 49.4 kWh depending on the terminal (or 48.9 kWh depending on the advertised capacity of the battery). This represents a price of € 29.10, or € 15.64 / 100 km.

On this typical trip, we made three top-ups for a total net amount of € 61.13 (excluding the operator’s expenses). At our last loading stop in the Darvault rest area after a journey of 430 km, the total cost was € 14.21 / 100 km. This is one of the highest right now, due to longer reuse times.

ABRP and ChargeMap route planner: wet finger

The MG ZS EV is fishing for another point: that of the route planner, as it simply does not offer it. Therefore, you should rely on your own estimates or planners for mobile routes. And if the SUV has connectivity for smartphones with mirror function, they can only be seen on the phone. A roadmap 2.0 in short, hardly conceivable aboard a modern car.

Therefore, we have maintained our travel habits with this type of vehicle, with the aim that a first stop at Fastned station arrives with a minimum of 10%. Initial capital: 75% SoC. Enough to reach grip with a rate of 8% on arrival to refuel at 65% after 30 minutes of immobilization. A few minutes less than in the second stage with 34 minutes in an Ionity terminal of Maison-Dieu. Here we could have filled up to 100%, sure to cross (only) the finish line with our goal of 20% after 500 km. But there’s no reason to regret the end of the load being too long, as it would never be as fast as our last 12-minute stage, even in the best of worlds.

In the end, our internal planning involves a time of 5:40 for 500 km of travel, with 4 hours 24 hours of driving and 1:16 hours of recharging. With our arbitrary flat rate of 4 minutes per rest area (evolution time and start / stop recharge), the total time is 5:52. Just 10 minutes longer than Megane e-Tech.

Compared to the consumption we have recorded and the evolution of charging rates, it is A Better Route Planner that is closest to reality. ChargeMap is a bit more optimistic, distorting loading times accordingly. Too bad, because the announced times are strictly close to the ones we observed. In addition, it expects additional stops with a full 15 to 32% (14 min) in the Couline area, and another 15 to 44% in the Darvault area (14 min, too). A Better Route Planner is more consistent proposing to recover 74% in the Lochères service area (compared to 46% according to ChargeMap), to skip a stage.

In short, everyone has their own view of things here, with a rigorous loading map in travel times, but more optimistic in recharging times, and quite the opposite with ABRP. If ChargeMap is closer to reality in total travel time (-13 min), A Better Route Planner (+20 min) makes more consistent choices here.

What is the Supertest?

Lovers of numbers and allergic to the official tabs, the Supertest, the new test format of Automobile-Propre, is made for you, gathering the data collected during a test in real conditions and according to a transparent and precise protocol. We will add them next Wednesday to our summary article allowing to compare the annotated values ​​of the tested models, which will make all the value of the heading.

If you want to go further, feel free to check out our tests and exchange with the community in our discussion forum.
