Claim 18:
19. An electric vehicle 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, and
the primary module converter separates a constant high-voltage area of the high-voltage battery pack from a low-voltage area of the electric vehicle;

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, wherein the main switch is a part of the low-voltage area;
high-voltage contactors connected to the bus bars of the high-voltage battery pack and configured to separate or interconnect the constant high-voltage area of the high-voltage battery pack and a controllably isolated high-voltage area of the electric vehicle;
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;

a vehicle converter connected to the high-voltage contactors by a high-voltage DC bus and separating the controllably isolated high-voltage area from the low-voltage area;
an inverter connected to the high-voltage contactors by a high-voltage DC bus; and
an electric motor connected to the inverter by a high-voltage AC bus, wherein the inverter and the electric motor are parts of the controllably isolated high-voltage area.
