1. An electric-vehicle battery system comprising:
a high-voltage battery pack comprising bus bars and multiple battery modules interconnected by the bus bars, wherein each of the multiple battery modules comprises battery cells and a primary module converter constantly connected to the battery cells;
a main switch connected to the primary module converter of each of the multiple battery modules and configured to switch between an activated position and a deactivated position;
high-voltage contactors connected to the bus bars of the high-voltage battery pack; and
a battery controller connected to the high-voltage contactors and also connected to the primary module converter of each of the multiple battery modules and configured:
to connect the high-voltage contactors when the main switch is in the activated position and power is received at the battery controller from the primary module converter of each of the multiple battery modules, and
to disconnect the high-voltage contactors when the main switch is in the deactivated position and the power is not received at the battery controller from the primary module converter of each of the multiple battery modules.
