Abstract

Devices, systems, and methods for constant and reliable power distribution, using a redundant power bridge battery architecture, in autonomous vehicles are described. An example method includes determining that each of a plurality of sensors is operating within in a nominal range for the respective sensor, and distributing, based on the determining, power from at least one alternating current (AC) power source or at least one direct current (DC) power source to at least one power distribution unit (PDU), wherein a first power bridge is coupled to the at least one AC power source and the at least one DC power source and a second power bridge is coupled to the at least one DC power source and the at least one PDU, and wherein the plurality of sensors is used to monitor a health of the vehicle and any single point failure is detectable.
