A method of controlling a drive system torque of an electric vehicle for generating a torque by evading a backlash band to prevent the occurrence of backlash in the drive system includes determining, by a controller, whether a plurality of predetermined entry conditions for entering a responsiveness priority mode of the vehicle are satisfied in a predetermined order based on vehicle driving information in a state in which control of a power priority mode is performed, and transitioning, by the controller, a mode to the responsiveness priority mode when it is determined that the plurality of entry conditions are sequentially satisfied and performing control of the responsiveness priority mode.

A battery pack including a first subset of battery cells and a second subset of battery cells, set of switches, a DC output port and an AC output port. The battery pack may provide both a DC output signal at the DC output port and an AC output signal at the AC output port by selectively activating the switches of the set of switches. The battery pack may couple the first subset of battery cells and the second subset of battery cells in a parallel configuration or a series configuration.

A motor system designed to replace and internal combustion engine. The motor system may include an electric motor and a battery that provides power to the electric motor. The system may also include control electronics to control the battery discharge current. The battery discharge current may be a relatively low current if the motor speed is less than a first threshold. The battery discharge current may be a relatively high current if the motor speed is greater than the first threshold but less than a second threshold. The battery discharge current may be the relatively low current if the motor speed is greater than the second threshold but less than a third threshold.
