Mercedes-Benz EQV DC Fast Charging Analysis

It’s strong, but does not beat the Mercedes-Benz EQC.

The Mercedes-Benz EQV 300 is a luxurious all-electric van, equipped with a big 100 kWh battery and ready for long distance travel. In this post we will try to analyze its fast charging capabilities, using test results released recently by Fastned.

Charging power vs state-of-charge (SOC)

Let’s start with the charging curve, which in the case of EQV is pretty flat. The peak seems to be around 110 kW, which is in line with the specs.

The charging power decreases gradually, after 50% SOC and then even more after about 85% SOC. Nonetheless, even at 90% it’s still at 50 kW.

The manufacturer says that 10-80% DC fast charging should take about 45 minutes. There is also a three-phase 11 kW on-board charger.

Comparison of charging power

The EQV has a noticeably bigger battery than the Mercedes-Benz EQC 400 SUV, but when we compare the two side-by-side, it turns out that the EQC is slightly ahead of the EQV.

A few more kW peak, and a few kW higher average from 20-80% SOC (100 kW vs 95 kW).

Comparison of charging rate

Assuming that the EQC has an 85 kWh pack (the usable capacity is around 80 kWh), it actually works harder than the one in the EQV.

Comparison of range replenishing speed

And the final chart – because of the huge differences in energy consumption, the EQC can easily win any long-distance race because it replenishes range much faster:

General info:

* Some values on the charts are estimated from the data source.

** Temperature of the battery cells might highly negatively affect charging capabilities. We don’t have data about temperatures of the battery at the beginning and during the charging process. In cold or hot weather, as well as after driving very dynamically, charging power might be significantly lower than shown on the charts (in extreme cases charging might be impossible until the battery temperature will not return to an acceptable level).
