The invention discloses a new national standard electric vehicle motor power auxiliary device. The new national standard electric vehicle motor power auxiliary device comprises a box body, a transmission cavity is formed in the box body, a placing cavity is formed in the box body in a mode that the inner wall of the upper side of the placing cavity communicates with the inner wall of the lower side of the transmission cavity, and a power motor is fixedly arranged on the inner wall of the lower side of the placing cavity. According to the new national standard electric vehicle motor power auxiliary device, by using load current change caused by rising of output power of an electric vehicle when the electric vehicle goes uphill, an auxiliary motor is controlled to carry out auxiliary power compensation on a power output shaft, so that the torque and the rotating speed of the power output shaft are improved, the problem of insufficient climbing power caused by power limitation of a new national standard electric vehicle is solved, meanwhile, automatic auxiliary heat dissipation is carried out on the new national standard electric vehicle when a power supply works at high load, and damage of internal components caused by overheating of the power motor is effectively avoided; and in addition, the device further carries out automatic speed limitation on the electric vehicle when theelectric vehicle goes downhill, and the danger caused by the reason that the speed of the electric vehicle is too high and the electric vehicle is difficult to control is avoided.
本发明公开的一种新国标电动车辆电机动力辅助装置,包括箱体,所述箱体内设有传动腔,所述箱体内设有上侧内壁与所述传动腔下侧内壁贯通设有放置腔,所述放置腔下侧内壁上固定设有动力电机,本发明利用电动车辆在上坡上输出功率上升带来的负载电流变化,控制辅助电机对动力输出轴进行辅助动力补偿,以提高动力输出轴的转矩与转速,解决了新国标电动车辆由于功率限制造成的爬坡动力不足的问题,与此同时在动力高负载工作时对其进行自动辅助散热,有效避免了动力电机因过热造成的内部元件损坏,此外,本装置还对电动车辆的下坡状态进行了自动速度限制,避免因电动车辆速度过快而难以控制发生危险。
