For a long time, we only focused on the hardware BOM cost, and did not think much about the iteration cost, vehicle manufacturing cost, user maintenance cost, and “software value of hardware”. After the traditional power distribution box is upgraded to the intelligent power distribution box, it brings digitization and generates data; however, data alone is not enough, and the granularity is not enough, and the amount of data is too large and there is no dimension. After refinement, multi-dimensional data appears in combination with usage scenarios; coupled with fast iterative algorithms, and then back to usage scenarios, data + algorithms + scenarios are synergistic.
