Understanding Autocharge on Alfen EV Chargers
What is Autocharge?
Autocharge is a method of starting EV charging sessions without using an RFID card. It leverages digital communication between the EV and the charger to authorize charging based on a unique EV identifier (EV idTag).
Benefits of Autocharge:
- No need for RFID cards after initial setup.
- Seamless experience for regular users.
- Only requires the charger and the CPO’s back office (OCPP).
- Boosts charger occupancy rates.
How It Compares:
| Method | Description | User Effort |
|---|---|---|
| RFID Card | Swipe card to start charging | Medium |
| Autocharge | One-time setup, then plug & charge | Low |
| Plug & Charge | Fully automated via ISO15118 | Lowest |
