You don't. Unless you want to keep some other factor like the the RPM or current draw of the motor to a constant number.

kV is RPM per volt. So if you want to keep RPM as a constant the kV is lowered when volt is increased. However the relationship may NOT be so simple since kV is a measure of RPM with no load.
