Abstract For the shortcoming of the chemical batteries in ups, we researched the charge control strategy of the flywheel battery,and which was used in the new UPS system based the flywheel battery. the vector control strategy was used in the charge control of flywheel battery through coordinate transformation. The stator current of flywheel battery motor was decomposed into d-q axis current, we controlled id equal to 0, then the charge current was controlled if we controlled iq. On the basis of the modeling, we did the simulation and experiment. The simulation and experimental results show that the permanent magnet synchronous motor has good performance with this control strategy, so it can meet the requirements of the flywheel battery’s fast charging.
