Smart charging
Controlling when and how fast vehicles charge to fit grid capacity, electricity prices and departure times, rather than charging at full power on arrival. A depot of buses uses it to stay within its grid connection; homes use it to charge on cheap night tariffs.
- Also called
- managed charging, load management
Example
The limit sets the permitted current
Requested current: 8 A. At 50 °C the chosen limit permits 5 A.
Breakpoints are invented teaching values, not operating limits for a particular battery.
Explore the graph
A requested current is clipped wherever an active limit is lower.
Requested current: 8 A. At 50 °C the chosen limit permits 5 A.
I_command = min(I_requested, I_limit)
Illustrative model. Breakpoints are invented teaching values, not operating limits for a particular battery.

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.
