US 11,299,049 B2 · System and method for integration of redundant bus architecture into a power system

Abstract

The present disclosure relates to a vehicle power system. In some examples, the vehicle power system can include a plurality of redundant low-power buses coupled to respective low-power batteries. The low-power buses can be powered by a vehicle battery having a higher voltage than the voltage of the low-power batteries by way of a DCDC converter, for example. In some examples, the DCDC converter can be coupled to the low-power buses via a plurality of switches included in an Auxiliary Voltage Controller (AVC). The DCDC converter and the AVC can be housed in a common package to reduce the size, weight, and complexity of the power system while also improving the power system's durability.

Dependent claims

A module comprising:

a housing enclosing:
a first controller comprising a plurality of switches;
a DCDC converter operatively coupled to a first battery, and operatively coupled to a second battery and operatively coupled to a third battery via the plurality of switches of the first controller, the DCDC converter configured to:
receive as an input a first voltage from the first battery;
and
output a second voltage to the controller, wherein:
the first battery, the second battery, and the third battery are all external to the housing;
and
a second controller operatively coupled to an input/output port, the DCDC converter, and the first controller, the second controller configured to:
receive a testing protocol from the input/output port;
and
execute the testing protocol on the DCDC converter and the second controller.
