Abstract: An example energy source for a work machine includes multiple battery cells connectable in parallel to form a battery system having a high pole and a low pole, a load bus to distribute energy from the battery system to the work machine, and a single point of connection between the battery system and the load bus. The single point of connection is a connector including a dual-pole single-throw (DPST) switch. The DPST switch includes a dual-switched circuit path to connect the high pole and the low pole to the load bus, and a single-switched circuit path to provide a switched connection of a high voltage interlock loop (HVIL) circuit.

Abstract: A system for balancing battery cell charge in a battery array for an electrified machine is provided. The battery array includes a plurality of individual battery cells, or groups of battery cells. A plurality of cell monitors are in communication with the individual battery cells, or groups of battery cells, with the plurality of cell monitors being powered by the individual battery cells, or groups of battery cells. A battery controller of the system receives information about the individual battery cells, or groups of battery cells, from the plurality of cell monitors. The information traverses the plurality of cell monitors in a first pattern to the battery controller and, after a predetermined period of time or occurrence of a predetermined event, the information traverses the plurality of cell monitors in a second pattern that is different than the first pattern to the battery controller.

Abstract: A controller of a machine identifies that a battery of the machine is connected to an electrical power connector component. The controller then causes one or more charging components of the battery of the machine to be enabled, then cause one or more electrical components associated with the battery of the machine to be enabled, then causes one or more cooling components of the machine to be enabled, then causes one or more propulsion components of the machine to be disabled, then causes one or more accumulator components of a hydraulic system of the machine to bleed, and then causes one or more non-accumulator components of the hydraulic system of the machine to be enabled. In this way, the controller causes the battery of the machine to enter into a charging state.

Abstract: A monitoring circuit for a battery system of a work machine includes a system controller configured to operate in a low power mode when the battery system is inactive, a sensing circuit element configured to produce an electrical sensor signal representative of an environmental parameter of the battery system, and a wakeup circuit configured to generate a controller activation signal when the sensor signal indicates that the environmental parameter is outside of a specified operating range. The system controller is configured to initiate a controller boot operation in response to the controller activation signal.

Abstract: A system for charging a battery unit to power a work machine. The system includes a charger to charge the battery unit, charging receptacles, power supply connectors, and a charging controller. The power supply connectors are configured to be received into the charging receptacles to attain connections between the charger and the battery unit. The charging controller is communicably coupled to the charger and is configured to receive an input corresponding to a net charge capacity of the battery unit; determine a power to be supplied to the battery unit by the charger to charge the battery unit in response to the input; and supply the power to the battery unit from the charger through the connections. The power to be supplied to the battery unit corresponds to a maximum possible power that meets the net charge capacity of the battery unit in the shortest possible time.

Abstract: A driving circuit to control/drive a contactor using a high-side driver integrated into the battery pack controller. The driver circuit may electrically isolate the controller pins of the battery pack controller (which interface the contactors) from the low-voltage digital processing core of the battery pack controller. The driver circuit may provide techniques to diagnose a fault by monitoring the voltage at the output of the driver as compared to the reference voltage. The driver circuit may include an electronic switch, such as a field-effect transistor, that is configured on the high side of the contactor to control voltage from an energy source to the contactor.
