In new energy vehicles (pure electric for example), the high-voltage harness can be divided into 5 major parts

(1) Power battery high-voltage cable: the harness connecting the power battery to the high-voltage box ;

(2) Motor controller cable: i.e., the harness connecting the high-voltage box to the motor controller ; 

(3) Fast charging harness: the harness connecting the fast charging port to the high-voltage box ; 

(4) Slow charging harness: the harness connecting the slow charging port to the vehicle charger ; 

(5) High voltage accessory harness (high voltage harness assembly): that is, the harness connecting the high voltage box to the DC/DC, vehicle charger, air conditioning compressor, air conditioning PTC.
