摘要：本文研究了混合動力汽車電化學電池的替代解決方案。“機械電池”是由帶有電機的小型鋼質飛輪混合動力汽車組成，可以存儲約幾十kJ 的能量。該能量足以滿足混合動力汽車燃料最優化的需求，并且足夠低，不會產生嚴重的回轉問題。這種裝置可以安裝在傳統汽車中12V 電池的位置，通過三相逆變器作為接口，連接到混合動力汽車直流母線上。 敘詞：混合動力汽車，飛輪，三相逆變器 Abstract：The paper explores an alternative solution to the electrochemical battery for hybrid power automobiles. The so-calledmechanical battery is maded up of small-type steel flywheel hybrid power automobiles with motors, which can store tens of kJ energy. Thestored energy can meet the optimal fuel requirements for hybrid power automobiles, and it is low enough not to result in serious gyration.The device can be installed in the position where a traditional car has 12V battery, and can be connected to the DC bus bar of the hybridpower automobile, via the interface of three-phase inverter.
