摘要： A method for determining a state of a fuse in a battery pack is provided. The battery pack comprises a first string comprising a first string fuse; at least one parallel arrangement comprising a battery cell and a resistor; and a first ammeter. The parallel arrangement is configured to be changeable between a connected state wherein the resistor is connected in parallel to the battery cell and a disconnected state wherein the resistor is disconnected from the battery cell. A second string comprising at least one battery cell is connected in parallel to the first string. The method comprises changing the at least one parallel arrangement of the first string to the connected state, and measuring a current passing through the first string. In an event that the change in the first current does not exceed a threshold, the first string fuse is in a blown state.

摘要： A cooling system, for circulating air through an electrical system for a work machine, includes an electrical cabinet, a chassis of the wok machine, and a blower fluidly connected to the electrical cabinet and the chassis. The electrical cabinet defines an interior volume for accommodating a plurality of electrical components of the electrical system. The chassis defines a closed-loop passageway configured to receive air from the interior volume of the electrical cabinet. The blower circulates the air through the interior volume of the electrical cabinet and the closed-loop passageway of the chassis.

摘要： Systems and methods for managing a battery charge of a work machine are described herein. The battery charge is maintained using a source of power (or other source) while the work machine also uses the source of power to power the work machine and the systems associated with the work machine. In instances in which the source of power may be removed for use by the work machine, a modification request may be used to change the battery from primary mode of operation, where the battery charge is maintained at a lower level to maintain the life of the battery, to a secondary mode of operation where the battery is charged to a high charge. The higher charge can be used to accommodate work machine operations while the battery is removed from the source of power. The battery can thereafter be returned to the primary mode of operation.

摘要： Systems and methods for improving recordkeeping and analysis of an asset include creating and maintaining an integrated record about the asset. In some embodiments, the systems and methods include collecting data about an asset to form an asset data collection, recording the asset data collection in a record, analyzing at least a portion of the asset data collection to determine a characteristic of the asset, and recording the characteristic of the asset in the record. In some embodiments, recording the characteristic in the record includes adding the characteristic to the asset data collection.

摘要： An alternative fuel management system may include a base configured for arrangement on a supporting floor or other framework of a vessel and configured to support alternative fuel supply equipment. The system may also include a sealed enclosure sealingly coupled to the base and configured to surround the alternative fuel supply equipment. The system may also include the alternative fuel supply equipment and it may be arranged within the sealed enclosure. The alternative fuel supply equipment may include a high-pressure pump, a fuel filter, a transfer pump, and a high-pressure fuel delivery line extending across the sealed enclosure and configured to provide alternative fuel from the high-pressure pump to a combustion engine. The alternative fuel management system may also include a purge fluid system configured to deliver purge fluid to the combustion engine from a source of purge fluid.

摘要： A gaseous fuel engine includes an engine housing having a cylinder block with a combustion cylinder therein, and an engine head including an intake port, an exhaust port, a fuel port, and an igniter bore, each extending to a fire deck. The gaseous fuel engine includes a fuel admission valve movable to close and open the fuel port. A non-axisymmetric clearance is defined between an inner port surface and the fuel admission valve and directionally biases a flow of gaseous fuel from the fuel port. Related methodology is also disclosed.
