Abstract

The invention discloses a range extender for a green new energy electric vehicle. The range extender comprises a motor shaft and a motor shell, wherein the motor shaft is arranged in the motor shell through a bearing and can rotate relative to the motor shell; the motor shaft is sequentially provided with a left generator permanent magnet rotor, a brushless DC motor permanent magnet rotor and a right generator permanent magnet rotor at intervals from left to right; the inner wall of the motor shell is sequentially provided with a left generator stator group, a brushless DC motor stator group and a right generator stator group at intervals from left to right; the left generator permanent magnet rotor is located in the left generator stator group; the brushless DC motor permanent magnet rotor is located in the brushless DC motor stator group; the right generator permanent magnet rotor is located in the right generator stator group; and fan blades are arranged at the left end and the right end of the motor shaft respectively. The range extender is a whole life cycle design, and is high in reliability, environment-friendly and power-saving, and the service lifetime of a storage battery is prolonged.

Description

technical field [0001] The invention relates to the field of range extenders, in particular to a range extender for green new energy electric vehicles. Background technique [0002] At present, the battery life of electric vehicles is short and requires frequent maintenance and replacement.
