AC slow charging
Charging through the vehicle’s onboard charger from an AC socket or wallbox, at a few kilowatts up to 22 kW. It takes hours, keeps the cells cool and gently loaded, and is how most private cars are charged.
- Also called
- overnight charging, destination charging, Level 2
Example
Charging infrastructure: an example situation
A 100 kW model request does not establish real voltage, current, connector or negotiation compatibility.
Read AC slow charging alongside Charging modes 1–4 in this context. The IEC 61851 classes of conductive charging: mode 1 a plain domestic socket, mode 2 a socket with an in-cable control box, mode 3 a dedicated AC charging point with the control pilot, and mode 4 DC charging where the converter is in the station. Most public charging is mode 3 or 4.

This overview identifies the components to use. Follow the example in Lemonergy for their connections and settings.
- Set connection, tariff, window and target.
- Compare policies on this network.
Example. Connect a vehicle for eight hours with a cheaper window from hour 1 to hour 7.
Observe. Compare cost, peak power and departure shortfall.
This is deterministic policy comparison, not a forecast or economic optimum.
