The invention provides a vehicle-mounted battery charging and heating control method based on phase-shifted full-bridge synchronous rectification, which is characterized in that a circuit structure required by the method can be built only by adding a power switch device and two relays on the secondary side of a transformer on the basis of existing power electronic components in a common vehicle-mounted charger; corresponding topologies for executing battery alternating current internal heating and direct current charging and discharging control can be flexibly obtained through the relays. By executing closed-loop feedback control on the PWM process, the battery of the vehicle can be rapidly heated in the extremely cold environment, compared with the prior art, the 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控制方法,其在常见车载充电机中现成的电力电子元件基础上,仅需在变压器副边增加一个功率开关器件与两个继电器即可搭建出方法所需的电路结构,通过继电器能够灵活地得到用于执行电池交流内部加热、直流充电与放电控制的相应拓扑。通过对PWM调制过程执行闭环反馈控制,本发明能够实现车辆在极寒环境下迅速加热电池,相对于现有技术其过程更容易控制并能显著提高加热效率及均匀性。
