However, with the increase in vehicle electrical equipment, the number of fuses, relays, and electrical circuit input / output nodes that need to be integrated increases exponentially. This results in increasingly larger centralized control electrical boxes, increasing not only manufacturing costs but also the space they occupy on the vehicle, making the casing and circuit boards increasingly complex. Furthermore, because the number of fuses and relays varies between different vehicles, standardized customization is not possible. Summary of the Invention
