A vehicle propulsion system comprising: a propulsion electrical storage device electrically connected to a traction motor of a vehicle via a propulsion circuit, the propulsion electrical storage device configured to power the traction motor to provide tractive effort to propel the vehicle; a first switch device electrically connected to the propulsion circuit between the propulsion electrical storage device and the traction motor; an ancillary electrical storage device electrically connected to the traction motor via an ancillary circuit and configured to power the traction motor, the ancillary electrical storage device being a different type of electrical storage device than the propulsion electrical storage device; a second switch device electrically connected to the ancillary circuit between the ancillary electrical storage device and the traction motor; and a controller having one or more processors and operatively connected to the first and second switch devices, wherein the controller is configured to switch or maintain the second switch device in a closed state during an elevated demand period for the ancillary electrical storage device to supply electric current to the traction motor via the ancillary circuit to power the traction motor, and the controller is configured to switch the second switch device to an open state to block conduction along the ancillary circuit prior to switching the first switch device from the open state to the closed state to enable the propulsion electrical storage device to supply electric current to the traction motor via the propulsion circuit to power the traction motor.
