Abstract
A vehicle includes an electric machine, a starter-generator, and a controller. The electric machine is coupled to a traction battery via an inverter. The starter-generator is mechanically coupled with an engine and electrically coupled with a low-voltage battery. And, the controller charges the low-voltage battery with power from the traction battery, and in response to a torque demand of the electric machine falling below a threshold defined by losses of the inverter, transitions to the starter-generator to charge the low-voltage battery.
