A battery pack monitoring apparatus is provided. The apparatus includes a voltage measurement system configured to couple to opposed ends of each of a plurality of blocks of a battery pack and to measure voltages thereof, the blocks being coupled in series by interconnects each having an interconnect resistance. The voltage measurement system is configured to derive an internal resistance of each of the plurality of blocks based upon the voltages of the opposed ends of each of the plurality of blocks and based upon a measurement of current of the battery pack and derive the interconnect resistance of each of the interconnects based upon the voltages of the opposed ends of each of the plurality of blocks and based upon the measurement of current.

Method of connecting cell voltage sensors

According to a preferred embodiment of the invention, the system for managing a power system with a plurality of power components that includes power source components and power consumption components includes a central power bus, a plurality of adaptable connectors that each electrically couple to a power component and to the central power bus, and a control processor that receives the state of each power component from the respective adaptable connector and is configured to balance the voltage and current output from each power source component to provide a desired power to a power consumption component based on the received states.
