Abstract

See full text

An electrical power circuit (100) is disclosed, comprising a charging input (102) for receiving electrical energy at a first or second voltage for charging a traction battery (106) of the vehicle; a battery connection terminal (104) for electrically connecting to the traction battery to supply electrical energy from the charging input for charging the traction battery at the first or second voltage and to receive electrical energy from the traction battery to power one or more traction motors (108) of the vehicle at the second voltage; and a DCDC converter (112) coupled to the charging input and to an output for connecting the DCDC converter to an electrical bus for providing power to one or more electrical units at an output voltage, the DCDC converter configured to receive electrical energy from the charging input, and to provide electrical energy at the output voltage whilst the traction battery is charged at the first voltage.
