A battery system for an electric vehicle includes a fixed cover, and a removable cover arranged over battery modules and a high voltage distribution system. The battery system includes a busbar arranged at least partially over a region of the battery modules and under the removable cover. The busbar includes a fixed section and a movable section, or a hinge, such that the busbar can be repositioned out of the way. The support tray includes a link between the fixed and movable sections. Floating fasteners, allowing at least one of radial float and axial float are used to secure the link to the support tray, thereby avoiding safety hazards and reducing the potential for short circuits in high voltage distribution systems or conductors thereof. The floating fasteners include a head, a neck, an engagement section, and a washer, which prevent removal from a component once installed.

A device and a method for controlling OTA update of a vehicle, to automatically set an optimal current consumption regardless of a vehicle model and an option for each vehicle model, includes a sensor configured for measuring a current consumption of a battery provided in the vehicle, and a controller that sets an initial current consumption to the vehicle, determines whether the OTA update is possible based on the initial current consumption and an expected over the air (OTA) update time, and determines an optimal current consumption based on the initial current consumption and an average current consumption during the OTA update.

An apparatus for covering an open top of a transportation trailer container, such as a chip train carrying wood chips, is provided. A flexible cover (e.g. tarp) may be deployed and retracted using a roller moved overtop of the container using pivotable arms. An electrically powered covering mechanism automatically deploys and retracts the cover. The covering mechanism is powered by a supercapacitor, which is charged when connected to an external power source. A charging control circuit can selectably allow or inhibit charging of the supercapacitor depending on power demands of other electrical loads.

An integrated power supply includes a first low voltage DC-DC converter (LDC) that converts supply power to a first output voltage and provides the first output voltage to a first auxiliary battery and a first electric load connected to each other in parallel; a second LDC that converts the supply power to a second output voltage and provides the first output voltage to a second auxiliary battery and a second electric load connected to each other in parallel; and an integrated controller that controls the first LDC and the second LDC to change output voltages of the first LDC and the second LDC. The first auxiliary battery and the second auxiliary battery are connected in series, and when the first LDC fails, the second LDC outputs a second increase output voltage that is higher than the second output voltage under control of the integrated controller.
