  "textContent": "This application provides a stator core, a housing, a motor cooling system of an electric vehicle, and an electric vehicle. The cooling system includes a power apparatus, a stator core, a core cooling oil passage for conveying cooling oil to the stator core, and a coil cooling oil passage. The coil cooling oil passage includes a first oil outlet that is at an end portion of the stator core. The core cooling oil passage and the coil cooling oil passage are sequentially connected. In this case, cooling oil first enters the core cooling oil passage, and then enters the coil cooling oil passage. The core cooling oil passage extends in a circumferential direction of the stator core. The coil cooling oil passage extends in an axial direction of the stator core. The power apparatus drives the cooling oil to enter the core cooling oil passage from an oil inlet, flow through the core cooling oil passage, and enters the coil cooling oil passage from an oil through port. The cooling oil flows back to an oil return groove from the first oil outlet.",
