1. An electrical power split device (ePSD) for Automated-Connected-Electrified (ACE) Heavy-Duty Trucks (HDTs) comprising:
a first port, adapted to be AC connected with a generator set of the ACE HDT bidirectionally and electrically;
a second port, adapted to be AC connected with at least one driving motor of the ACE HDT bidirectionally and electrically;
a third port, adapted to be DC connected with at least one power battery pack of the ACE HDT bidirectionally and electrically;
a fourth port, adapted to be DC connected with a brake resistor of the ACE HDT unidirectionally and electrically;
a DC junction, adapted for collecting and distributing direct current from the first port, the second port and the third port;
an AC-DC converter, connected between the first port and the DC junction;
a DC-AC converter, connected between the DC junction and the second port;
a DC-DC converter, connected between the DC junction and the third port; and
a voltage-controlled switch, connected between the DC junction and the fourth port and configured to: be in an ON state or OFF state based on a voltage of the DC junction.
