3results about How to "Guaranteed redundancy" patented technology

A voltage measuring device may include a bus bar electrically connected to a first terminal and a second terminal of a battery cell, the bus bar extending in a first direction. The shunt resistor may be located on the bus bar and extend in a second direction crossing the first direction. The measurement unit is configured to measure a first voltage value applied to a first sub-region of the shunt resistor, and to measure a second voltage value applied to a second sub-region of the shunt resistor.

The application belongs to the technical field of unmanned driving, and specifically discloses a mine area road waterlogging detection method based on fusion of vision and laser radar, which comprises the following steps: acquiring image data and performing waterlogging segmentation; acquiring point cloud data, removing non-waterlogging point cloud to obtain a first segmentation result, and performing segmentation according to waterlogging semantic segmentation labeling to obtain a second segmentation result, and fusing to obtain a waterlogging recognition result; judging whether the image confidence degree is qualified or not; extracting ground point cloud in the point cloud data and modeling to obtain a fitting plane, projecting the edge contour pixel data to the fitting plane to construct a point cloud convex hull contour, and recognizing the point cloud convex hull contour to obtain the waterlogging recognition result; and has the following advantages: the multi-sensor fusion sensing mode can effectively deal with the problems existing in the single-sensor sensing, and has higher real-time performance, robustness and high confidence degree.

The application discloses a vehicle integrated lithium battery high-voltage power distribution system and a control method. The lithium battery high-voltage power distribution system comprises a high-voltage distribution box, a plurality of battery boxes and a connecting cable for connecting the high-voltage distribution box and the battery boxes and two groups of the battery boxes, which are stacked from top to bottom. The high-voltage distribution box is integrated with a control panel, a filter, a DCDC, a contactor, a fuse, a hard copper bar and a current sensor. The battery box is integrated with a BMS control box. The battery boxes are also connected with liquid cooling pipelines. The system effectively reduces the space occupied by the high-voltage power distribution system on the chassis by using the integrated design of the lithium battery high-voltage power supply and distribution system. By integrating multiple functional modules in one whole, the device layout and installation space are saved, the complexity of the system and the high-voltage cable wiring are reduced, the generalization and interchangeability of the lithium battery and the high-voltage power distribution system are improved, and the redundancy of the vehicle power supply and distribution system is ensured.
