The invention discloses a composite electric vehicle energy recovery device and relates to the technical field of new energy vehicles, in particular to an energy recovery device, and aims to solve theproblems that a large part of converted electric quantity is wasted and the energy recovery efficiency is extremely low due to the fact that large-current, high-voltage and small-current and low-voltage output energy storage batteries generated during recovery in an existing energy recovery mode cannot be absorbed. In the invention, by combining pneumatic energy storage and rotary power generation, the pneumatic energy storage is that vehicle mechanical energy is converted into gas compression energy to be stored, and compressed gas needing to be stored is released to drive a vehicle to moveforwards; rotation power generation is carried out through rotation energy of an automobile wheel shaft, and a storage battery is charged after power generation. The method is used for energy recoveryof the electric automobile.
一种复合式电动汽车能量回收装置,涉及新能源汽车技术领域,是为了解决现有的能量回收方式回收时产生的大电流、高电压以及小电流和低电压输出的那部分能量蓄电池不能吸收,使转换出的很大一部分电量被浪费掉了,能量的回收效率极低的问题。本发明采用气动储能与转动发电相结合,所述的气动储能是通过车辆机械能转化为气体压缩能加以储存,需要储存的压缩气体时再释放出来驱动车辆前进;所述的转动发电是通过汽车轮轴转动的能量进行发电,发电后对蓄电池进行充电。本发明用于电动汽车的能量回收。
