Systems and methods for charging an electric bus having a charging interface on its roof may include determining that an approaching bus is supposed to be charged at the charging station, lowering the charging head of the charging station to land on the roof of the bus, and moving the bus with the charge head on its roof to engage the charging head with the charging interface.

A system and a method for managing a charging station allow charging a battery of a connected autonomous electric vehicle for carrying passengers in a controlled environment. A controller connected to the charging station determines and modulates a charging rate with which the charging station charges the battery based on a duration between a start of charging the vehicle and a forecasted time of start of duty mode of the vehicle. The duration is determined by the controller based on a forecasted passenger load as a function of time.

A control unit of an electric vehicle receives a signal indicative of an operator desired torque and sends a signal to the traction motor to output a value of torque that is the algebraic sum of the operator desired torque and a torque modification factor calculated by the control unit. The control unit calculates the torque modification factor from an efficiency map of the motor which indicates the efficiency of the motor as a function of its output torque and rotational speed.
