A cooling and lubrication system for a hybrid powertrain is disclosed. The cooling and lubrication system comprises a water cooling module and an oil cooling module. The water cooling module comprises a water inlet nozzle (1), a first water passage (2), a second water passage (3), an oil cooler (4) and a water outlet nozzle (5) connected in sequence. The first water passage (2) is arranged on a housing of the drive motor, and the second water passage (3) is arranged on a housing of the reducer. The oil cooling module comprises an oil pump (6), a first oil delivery passage, a second oil delivery passage, a third oil delivery passage, a first oil return passage and a second oil return passage. An oil inlet of the oil pump (6) is communicated with a bottom of the housing of the reducer, and an oil outlet of the oil pump (6) is communicated with the oil cooler (4). The lubricating oil in the oil cooler (4) is delivered into the housing of the reducer, the housing of the drive motor and the housing of the range extender respectively via the first oil delivery passage, the second oil delivery passage and the third oil delivery passage. The first oil return passage is arranged at the bottom of the housing of the drive motor, and the second oil return passage is arranged at the bottom of the housing of the range extender. The cooling and lubrication system uses an integrated cooling and lubrication means, which makes the structure of the hybrid powertrain more compact and the cooling and lubrication efficiency higher.
