Max charger voltage capability is a vehicle/charger interoperability requirement for newer vehicles when charged at a HV DC charge station.
New EVs recently or soon to launch often have higher voltage capability then many HV DC chargers.
Some examples: Porsche Taycan & Audi e-tron, Lucid Air, & some Commercial Vehicles are in the 650 V - 800 V Range.
Many older EV designs (Tesla and others) require only ~400 V.
Could Max Voltage Capability of HV DC charge station be added as a filter-able criteria similar to charge port type, charge speed, etc?
While this could be added to both our app and our API the main problem is that the data will often not be populated, so if you restrict your search based on that criteria you would miss results that were still compatible with your vehicle.
You mentioned that max voltage is an interoperability requirement - are you aware of production vehicles which simply cannot use these new charging locations because of voltage incompatibility despite having the correct connector?
That said, if someone wants to submit pull requests for the relevant code (API, App, tests etc) I’m sure it would be integrated assuming it was correct.
Yes as newer, higher voltage vehicles come to market some will not have provisions for charging at lower voltage chargers.
So the reason this feature would be useful is a high voltage vehicle without DC DC conversion capabilities would simply not charge at all if plugged into a low voltage charger.
That’s highly unlikely that any manufacturer would release a mass-market vehicle that is incapable of charging at the majority of chargepoints around today. Some buses etc that use dedicated charging facilities at depots have unusual configurations.
Some of the high-voltage designs work by effectively rewiring the traction battery, splitting the pack to work in parallel rather than in series during charging at 400V on regular DC chargers, when it’s normally 800V or such, yet when the charger negotiates the capability to charge at 800V it will remain in parallel. The 800V capable charge points that are publicly available can all work at the regular lower voltages.
