OBC = On-Board Chargers, the device that transforms AC do DC for your battery.
I live in a part of the world with very few DC Fast Chargers, but a decent number of Type 2 chargers with 22 kW, because Type 2 is much cheaper to implement (200 EUR for me).
Many popular EVs have very small OBC, limited in different ways:
- maximum kW
- just one AC phase
I have a Nissan Leaf 2018 (40 kWh) and my Type 2 port is limited to just one AC phase and 6.6 kW.
The paradox for me (living in Europe) is that in order to have 6.6 kW, I must usually have 3 Phase 22 kWh installation (32A).
The Renault Zoe has no DC fast port but can use 22kW on Type 2 connection with the internal OBC!
So, why de OBC limitation? Is a question of price? Weight? Or just plain step-by-step feature release?
