The invention relates to the technical field of energy systems, in particular to a bidirectional energy conversion system suitable for a sodium ion battery, and the bidirectional energy conversion system comprises a circuit connection assembly and a system connection assembly, and the circuit connection assembly is electrically connected with the system connection assembly. When the voltage of the battery system is lower than a rated value, the bidirectional energy converter starts to work, the voltage of the battery is converted to the rated value, inversion of motor control is facilitated, the power performance and endurance of a bicycle or an automobile are guaranteed, and when energy is fed back through braking of the whole automobile or other conditions, electric energy flows towards the battery through the motor controller, so that the electric energy is supplied to the battery. In this way, the bidirectional energy conversion system is also connected to work, the voltage of the motor controller is converted into a value similar to the actual voltage of the battery, and normal charging of the battery is guaranteed.
本发明涉及能源系统技术领域,尤其为一种适用于钠离子电池的双向能量转换系统包括电路连接组件和系统连接组件,所述电路连接组件与系统连接组件电性连接,本发明通过设置双向能量转换系统,介于电池系统和电机控制器之间,当电池系统的电压低于额定值后,双向能量转换器开始工作,将电池的电压转换到额定值,便于电机控制的逆变,保证自行车或汽车的动力性能,以及续航,并且通过整车制动回馈,或其他情况回馈能量时,电能经电机控制器向电池方向流动,这样双向能量转换系统也会接入工作,将电机控制器的电压装换成和电池的实际电压相近的值,保证电池的正常充电。
