Axle offers two EV charging solutions which enable you and your users to earn money from grid flexibility. Both solutions work by adjusting charging schedules to support the grid.

​
Controlling via car or charger

Axle can control EV charging through either a smart charger or the vehicle itself.
Via chargerVia car
ConnectionDirect to charger API or OCPPVia car manufacturer API
GeofencingNot required — charger is always at homeRequired — Axle only controls charging when the car is at home (boolean signal, no location data needed)
Best forCharger OEMs, white-label appsCar OEMs, white-label apps
When controlling via car, Axle uses a “car is home” signal from the car manufacturer before issuing any charging instructions — no location or GPS data is required, just a boolean indicating the vehicle is at home. In practice, this commonly means the manufacturer API only forwards plug-in events to Axle when the car is at home. This ensures Axle never issues charging instructions while the vehicle is at a public or workplace charger.
