Abstract: A power management and selection system for a class 8 tractor trailer, directs excess solar and vehicular charge capacity to an auxiliary load by measuring available charge capacity from a reefer power system including a reefer battery, solar panel and charge controller for moderating solar power to the reefer batter, and measuring available charge capacity from a cab vehicle power system including a propulsion system battery and alternator. Charge logic, in a selector configured for switching charge capacity to the auxiliary load, determines which of the reefer power system and cab vehicle power system has the most potential excess charge capacity, and directs the determined excess charge capacity to the auxiliary load, while the measured available charge capacity remains sufficient for powering the respective reefer power system or cab vehicle power system.

Abstract: Provided herein is a relay architecture for selecting between multiple power sources. In one approach, a first relay and first power source are electrically coupled to a first terminal. A second relay and second power source are electrically coupleable to a second terminal and to the first relay. A load is electrically coupled with at least one of the following in the case that a load voltage is below a predetermined threshold: the first terminal, the second terminal, and a third power source, wherein a power supply is provided to the load by the first power source in the case that the first power source is coupled to the first terminal. The power supply is provided to the load by the second power source when the second power source is coupled to the second terminal and the first power source is disconnected from the first terminal.

Abstract: A battery controller that controls a battery for supplying power to a load apparatus, includes a current detection unit that detects a discharge current and a charge current of the battery, a malfunction detection unit that detects malfunction of a voltage detector for detecting a voltage of the battery, and a contactor control unit that is provided on a power supply line through which the discharge current and the charge current flow to open/close a contactor. The contactor control unit integrates the charge and discharge current when the malfunction of the voltage detector is detected, calculates an actual charge current amount obtained by subtracting an integrated value of the discharge current from an integrated value of the charge current, and prohibits charging/discharging of the battery by controlling the contactor when the actual charge current amount is equal to or more than a predetermined value.
