The invention relates to a double-electric-drive-axle system and a vehicle. The double-electric-drive-axle system comprises a front electric drive axle, a rear electric drive axle and a first disconnection mechanism, the front electric drive axle comprises a front electric drive module, a rear electric drive module and a front axle differential mechanism module, the front electric drive module and the front axle differential mechanism module have a transmission connection working condition and a disconnection working condition, and the rear electric drive module and the front axle differential mechanism module are in transmission connection. The first disconnecting mechanism is in transmission connection between the front electric drive module and the front axle differential mechanism module, and the first disconnecting mechanism can control the front electric drive module and the front axle differential mechanism module to be switched between a transmission connection working condition and a disconnection working condition. The first disconnecting mechanism cuts off connection between the front electric drive module and the front axle differential mechanism module under the high-speed working condition, and the electric drive efficiency is improved. The double-electric-drive-axle system and the vehicle meet the use requirements of the whole vehicle for low-speed large-torque and high-speed working conditions, and are simple in structure, compact in structure, light in weight, simple in control scheme and low in cost.
