A controller generates a target motor torque and target accessory power information during operation of an electric vehicle. The target motor torque and target accessory power information maintain a DC-link of the electric vehicle powertrain within a safe DC-link operating range. The DC-link has a DC-link voltage that is used to supply an accessory device and a motor. The accessory device is disposed on the electric vehicle and includes vehicle indictors, hydraulics, or any other accessory involved in the operation of the vehicle. The motor drives the vehicle. The controller receives the DC-link voltage, motor speed, desired output torque information, desired accessory power information, and the safe DC-link operating range and generates therefrom the target motor torque and the target accessory power information.
