1. A method of charging an electric bus at a charging station, the electric bus including a charging interface on a roof of the bus, the charging interface being configured to connect with a charge head assembly of the charging station for charging, comprising:
- driving the bus towards the charging station;
receiving data from a plurality of RFID tags as the bus is moving towards the charging station;
using the received data to align the bus with respect to the charge head assembly;
lowering the charge head assembly to land on the roof based on the received data;
making contact between the charge head assembly and the charging interface; and
charging the bus.
