In the wake of the BBC’s “RapidGate” article last weekend I find myself debating the pros and cons of the 2018 model year Nissan LEAF that we road tested last week with a fan of the Hyundai Ioniq EV:
As you may possibly gather from our company name, #V2G capability is vital for our particular use case. Hence the #Ioniq is currently utterly useless to us. On the other hand we love the #LEAF, irrespective of its #V2x expertise. #YMMV!#ThoughtForTheDay – Horses for courses?

Dutch charging station operator Fastned helpfully provides some experimental evidence to inform the debate. Whilst they don’t publish data on the effects of successive rapid charging sessions on a long drive they do provide charging profiles for all three flavours of the Nissan LEAF:
which does indeed show the latest LEAF fitted with a 40 kWh battery pack throttling the charging rate earlier than the preceding 30 kWh version. According to Fastned:
With a Nissan Leaf or e-NV200 (Evalia) you use the CHAdeMO plug. The charge speed is up to 50 kW at all of our chargers. In the charge curve below you can see the charge speed of the Nissan Leaf and e-NV200. On average both cars charge 100 km of range in 20 – 25 minutes. Charging behaviour largely depends on the battery size:
24 kWh edition: fast charging until 25%, charging will gradually go slower after this
30 kWh edition: fast charging until 80%, charging will go slower after this
40 kWh edition: fast charging until 60%, charging will go slower after this
For comparison purposes here’s the equivalent graph for the Hyundai Ioniq:
According to Fastned once again:
If you have a Hyundai Ioniq, then you use the CCS plug. The charge speed is up to 70 kW at our next generation fast chargers and 50 kW at our other chargers. In the charge curve below you can see the charge speed of the Ioniq at both chargers. On average the Ioniq charges 100 km in 15 – 25 minutes. Above 75% the charge speed requested by the car will drop, and above 85% the charge speed is reduced to 22 kW.
