I'm looking into making an off-grid EV solar charger so I'm wondering: What is the slowest possible AC or DC charging possible? Is it possible to charge at 100w for example? More specific: What is the lowest wattage (or amps*voltage) that can be communicated to be available from an EV charger to an EV through existing communication protocols used by type 1/2 or CCS charging? I know around 700w is possible with my charger + lowering charging current in my car (doesn't say amps but I assume 230v*3a) but can it go lower than that? Or is it only possible by the car to limit further? Why I ask: Slower is better because it increases the area under the curve by allowing charging earlier as sun ramps up/using less solar panels.
