Abstract: A motor controller is described that is coupled to a drive motor and a battery pack of a vehicle. The motor controller is configured to determine a maximum discharge current of the battery pack and a rotational velocity of the drive motor. Based on the determined rotational velocity of the drive motor, the motor controller is configured to identify a curve that defines a relationship between the maximum discharge current of the battery pack and a drive current limit of the motor controller. Based on the identified curve and the determined maximum discharge current of the battery pack, the motor controller is configured to determine the drive current limit of the motor controller. The motor controller is further configured to convert a discharge current from the battery pack to a drive current subject to the determined drive current limit and supply the drive current to the drive motor.

Abstract: A propulsion control system has an electric motor configured to generate an axle torque in response to a final torque command, and has a motor constraint that specifies a maximum torque. A motor controller is configured to generate the final torque command in response to an intermediate torque command and a distributed power limit command. An open-loop function in supervisory controller is configured to calculate an initial torque command vector in response to a driver torque command, calculate an intended operating vector by mapping the initial torque command vector into a multidimensional power space, generate the intermediate torque command by clipping the intended operating vector in response to the motor constraint, generate a constrained command vector by clipping the intended operating vector in response to the motor constraint and a plurality of energy storage constraints, and generate the distributed power limit command in response to the constrained command vector.

Abstract: An apparatus for managing power of an electric vehicle and a method thereof are provided. The apparatus determines whether a user participates in a leisure activity based on surrounding information of the electric vehicle, and supplies power when a plug is connected to an outlet provided in the electric vehicle while entering a leisure mode to allow the user to use the outlet during leisure activities. The apparatus includes an information collector that collects surrounding information of the electronic vehicle, and a controller that determines whether a user is performing a leisure activity based on the surrounding information of the electric vehicle collected by the information collector and adjusts power supply based on whether an outlet provided in the electric vehicle is plugged in in a leisure mode indicating that the user is performing a leisure activity.

Abstract: A vehicle receives SoC information of the battery when the vehicle is in a parked state, determines whether a charged amount of the battery is lower than or equal to a preset charged amount based on the received SoC information of the battery, determines whether a current time is included in a use time zone based on use time information of the remote service when it is determined that the charged amount of the battery is lower than or equal to the preset charged amount, adjusts a cut-off time point of power supply of the battery in response to whether the current time is included in the use time zone, and transmits a power supply cut-off command of the battery to the battery management apparatus.

Abstract: An abnormality detection system includes a removable battery and a server. The removable battery has: a detector; a battery side acquisition unit for acquiring measured data that are the data of measured values measured by the detector and acquiring, from an object to be electrically driven, first recognition data for recognizing the object to be electrically driven; and a battery side storage unit. The server has: a server side storage unit for prestoring reference data that are the data acquired when the object to be electrically driven performs a predetermined operation; a server side acquisition unit for acquiring the measured data, the first recognition data, and second recognition data; and an abnormality detection unit for comparing actual work data obtained from the measured data with the reference data and detecting an abnormality when the difference between the actual work data and the reference data exceeds a threshold value.
