Analysis: Honda e Fast Charging Dissapoints

It aspires to be a premium EV, but fast charging performance is not strong.

Honda e is one of the most interesting electric city cars on the market – described as “Lovable Retro Urban EV” – however, in terms of DC fast charging, it’s quite basic.

Let’s take a look at Fastned’s fast charging results for the Honda e and compare it with other small EVs.

Charging power vs state-of-charge (SOC)

The manufacturer says that Honda e can charge at up to 50 kW and we saw some sessions with 49 kW peak. In the Fastned example, the peak charging power was a little bit lower, at 46 kW.

Fastned explains that it’s the session for a car with the battery in optimal conditions (temperature of around 30°C).

The highest power is available between 10-20% SOC and then it decreases in steps. The good thing is that it maintains around 20 kW from about 70% SOC to over 95% SOC.

We will compare the Honda e fast-charging results with several other small electric models, that were already analyzed:

  • Fiat 500 electric (42 kWh) 2021
  • Renault ZOE Z.E. 50 2019
  • Peugeot e-208 2020
  • BMW i3 (42 kWh) 2019
  • MINI Cooper SE 2020 (together with i3)
  • Volkswagen e-Up!, Škoda CITIGOe iV, SEAT Mii Electric (2020)

Comparison of charging power

If we compare the charging power, Honda e drowns in the sea of other models, basically trying to keep up with Volkswagen’s triplets (VW e-Up!, Škoda CITIGOe iV, SEAT Mii Electric) that are the slowest charging EVs that we analyzed.

The average power output in the 20-80% SOC window appears to be between Volkswagen’s triplets and Renault ZOE Z.E. 50 and that’s slow.

Comparison of C-rate

The comparison of C-rates reveals the problem. Honda e is around 1C (the peak is 1.3C, while the average in 20-80% SOC window is 0.8C). It’s not enough to be competitive.

Volkswagen’s triplets have a similar battery capacity and similar average. Only Renault ZOE has a lower average (0.6), but at least it has a high battery capacity of 55 kWh.

Comparison of range replenishing speed

The range replenishing rate is really disappointing in Honda e.

It has the lowest average in 20-80% SOC window among all models:

Conclusions

The conclusion from the DC fast charging analysis of the Honda e 2021 is that it offers very basic performance – just in case.

The charging power is low in relation to the battery capacity and turns out to be noticeably lower than in the case of most of the other small EVs, not even premium. The range replenishing rate is also bad.

Without any doubt, Honda could do better.

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).
