A battery electric vehicle includes: an accelerator pedal; a shifter; a mode selection device that selects a control mode for an electric motor from a manual mode and an automatic mode in accordance with a mode selection operation by a driver; and a motor control device. The motor control device varies an output characteristic of the electric motor for an operation of the accelerator pedal in accordance with an operation position of the shifter in the manual mode. The motor control device varies an output of the electric motor in accordance with the operation of the accelerator pedal, irrespective of the operation position of the shifter, in the automatic mode. When ACC is requested during control in the manual mode, the motor control device switches control for the electric motor from the manual mode to the automatic mode.

A power delivery system for an electric vehicle provides efficient power management for either continuous or intermittent high-performance operation, using a boost stage and an on-board charging circuit. A main battery, configured as a high-capacity power source, supplies power to the electric motor under normal load conditions. An auxiliary boost battery assists the main battery in supplying a high-level current at a higher discharge rate thereby causing the motor to operate in a high-performance drive mode. A charging circuit recharges the boost battery from the main battery during operation of the motor. The charging circuit also maintains a charge balance between the boost battery and the main battery when the two batteries have different chemistries. In one embodiment, participation of the boost battery in powering the electric motor can be controlled automatically according to sensed changes in the load. In another embodiment, power management can be based on timed intervals.

A method for adjusting a motor torque of an electric two-wheeled vehicle, including the following steps: reading in a driver assistance profile which represents a dependency of the motor torque on a pedaling action of the driver, determining at least one predefined range in the driver assistance profile, the range having at least one nonconstant change within the driver assistance profile, in particular in the slope of the driver assistance profile, and ascertaining a future speed of the electric two-wheeled vehicle as a function of an instantaneous speed of the electric two-wheel vehicle and a pedaling action of the driver. The motor torque is changed, in particular decreased or increased, as a function of the pedaling action of the driver, deviating from the driver assistance profile, based on a check as to whether the future speed of the electric two-wheeled vehicle is within the predefined range.
