"textContent": "A system for controlling a start-up operation of an electric vehicle includes a high voltage electrical propulsion unit and a controller. The high voltage electrical propulsion unit includes at least one battery pack, a high voltage bus, one or more power components, a first group of switches, and a second group of switches. An onboard charger is adapted to deliver adjustable current to pre-charge the high voltage bus during the start-up operation. The first group of switches selectively connect the at least one battery pack to a propulsion high voltage (HV) bus and the second group of switches selectively connect the at least one battery pack to a charge port high voltage (HV) bus. The controller is adapted to control operation of the first group of switches and the second group of switches to enable pre-charging of the high voltage bus during the start-up operation.",
