Claim 19:
20. A method of operating an electric-vehicle battery system comprising a high-voltage battery pack, a main switch, high-voltage contactors, and a battery controller, the method comprising:
putting the main switch into an activated position thereby (a) powering the battery controller from a primary module converter of each of multiple battery modules in the high-voltage battery pack and (b) connecting the high-voltage contactors using the battery controller, wherein the battery controller redistributes a portion of power, received from the primary module converter of each of the multiple battery modules to the high-voltage contactors for connecting the high-voltage contactors; and
putting the main switch into a deactivated position thereby (a) disconnecting the battery controller from the primary module converter of each of the multiple battery modules in the high-voltage battery pack and (b) disconnecting the high-voltage contactors using the battery controller by cutting power from the battery controller to to the high-voltage contactors.
