The invention provides a vehicle-mounted battery charging and heating system based on phase-shifted full-bridge synchronous rectification, which can fully utilize ready-made power electronic components in a vehicle-mounted charger, and on the basis of the ready-made power electronic components, only one power switch tube and two relay switches are additionally arranged, so that the functions of charging and heating a power battery are realized; the system has the advantages of being simple in composition structure, low in cost, small in occupied vehicle space and the like. According to the system, the principle of battery alternating current internal heat production is adopted during heating, decoupling control over the current amplitude and frequency is facilitated, the heating process is easier to control, and the heating efficiency and uniformity can be remarkably improved.

    本发明提供了一种基于移相全桥同步整流的车载电池充电加热系统,能够充分利用车载充电机中的现成电力电子元件,在其基础上仅通过增设一个功率开关管和两个继电器开关,即实现了对动力电池充电和加热功能,系统的组成结构简单兼具成本低、占用车上空间小等诸多优点。所述系统在加热时采用电池交流内部产热的原理,有利于电流幅值与频率的解耦控制,使得加热过程更容易控制且能够显著提高加热效率及均匀性。
