1results about How to "Average distribution" patented technology

This invention provides a power distribution unit and a charging device. The power distribution unit includes: a plurality of distribution components arranged sequentially along a first direction; each distribution component includes a circuit board and a plurality of onboard relays; the circuit board extends along a second direction, and each onboard relay is disposed on the circuit board; the second direction is perpendicular to the first direction; a bus assembly including a plurality of first busbars and a plurality of second busbars, the first busbars crossing at least one distribution component and connecting one end of each onboard relay located in different distribution components, the second busbars connecting the other end of each onboard relay located in the distribution component to connect or disconnect current loops through the onboard relays; an outer frame including at least two side frames arranged along the second direction; the two ends of the circuit board in the distribution component along the second direction are inserted and fixed to the corresponding side frames along a third direction. This power distribution unit has the advantages of small size, low cost, and convenient maintenance.
