Problems solved by technology

Ground unmanned vehicles are generally divided into three parts according to their functions: mobile chassis, task carrying operation, situation and autonomous perception. Since the design process of light and small unmanned vehicles draws on a large number of civilian product design concepts, their electronic load characteristics are very different. ;Mainly include traditional 28V control drive equipment, 12V lidar and autonomous perception equipment, and 48V computer equipment; the input power of the system is 28V battery and generator dual redundancy; the traditional power transmission mode often requires multiple The power conversion unit and the power distribution unit are used to realize the power conversion and transmission of different voltage levels, resulting in the congestion of the installation space of light and small unmanned vehicles and the increase of cost. Therefore, how to realize the safe and reliable distribution of power supply for multiple power supply equipment in a limited space It is the primary problem to be solved for light and small unmanned vehicles
