Zusammenfassung:	A passive lubrication system, for a gear drive system of a drive system, for powering an electric vehicle, includes an oil network, an oil sump region, an oil paddle, and an oil diverter. The oil network is defined by and disposed within, at least, a fixed annular region of the gear drive system and a planetary gear system. The oil sump region is configured to provide oil for distribution about the oil network. The oil paddle is operatively coupled with the planetary gear system, configured to rotate with a component of the planetary gear system, and during rotation, configured to course oil, from the oil sump region. The oil diverter is positioned concentric with the oil paddle and radially outward of the oil paddle and configured to receive oil from an oil source, upon rotation of the oil paddle, and direct the received oil to the oil network.
