An electric drive assembly of dry differential and a new energy vehicle are disclosed. The electric drive assembly of dry differential comprises a reducer and a differential. The reducer comprises a reducer housing and a reducer end cover. The differential is rotatably provided in the reducer housing and comprises a differential cover and a differential housing, the differential cover and the differential housing are fixedly connected, an end of the differential cover opposite from the differential housing is provided with a bearing mounting seat, an inside of a chamber formed is provided with a pair of side gears, a pair of pinion gears and a pinion shaft, both ends of the pinion shaft are fixed on the differential housing, the pinion gears are sleeved on both ends of the pinion shaft, the side gears are meshed with the pinion gears, an inner hole of the side gear is equipped with an side gear end cap. The side gear end cap in the electric drive assembly belongs to static seal, and has a simple structure and high sealing reliability. The differential oil seal is sealed with the outer circumference of the side gear, which, compared with the traditional structure in which the outer circumference of the half shaft is sealed, reduces the eccentricity and axial movement, and reduces the wear of the oil seal.
