Type C high-voltage distribution box is only used for
Its primary function is to distribute electrical power efficiently to various circuits or loads while ensuring accessibility for inspection, maintenance, and fault isolation. The USB standard has evolved from offering limited power alongside data transfer to become a primary flexible power source, widely used for charging devices like phones, tablets, and laptops. The European parliament has adopted a law requiring USB Type-C to be the mandatory cable for a large number. What is a high voltage box? The High Voltage Power Box combines the functionality of an Onboard Charger (OBC), a DC/DC converter and a PDU (Power Distribution Unit). The OBC is the interface between the car and the public grid. It converts the energy from the network grid AC (Alternative Current). USB‑C, or USB Type‑C, is a 24-pin reversible connector (not a protocol) that supersedes all previous USB connectors, which were designated legacy in 2014.
