1. A method comprising:
setting a compressor speed based on a battery temperature (TB) and a first system pressure (PH);
setting a fan speed based on a second system pressure (PL) and a powertrain temperature (TP);
setting a pump speed based on the second system pressure (PL) and the powertrain temperature (TP);
combining multiple flow paths of a first liquid into a single flow path when the powertrain temperature TP is below a first threshold temperature; and
splitting the single flow path of the first liquid into the multiple flow paths when the powertrain temperature TP is above a second threshold temperature.
