Example
Charging infrastructure: an example situation
A 100 kW model request does not establish real voltage, current, connector or negotiation compatibility.
Read NACS alongside DC fast charging in this context. Charging from a station that supplies DC straight to the pack, bypassing the car’s onboard charger, at 50 kW to over 350 kW. The BMS, not the charger, sets the current from moment to moment, which is why the charge curve tapers as the pack fills.
Use in Lemonergy
Separate compatibility from requested average power.
This is a reference concept. No executable Lemonergy block has been verified for this term.
