The embodiment of the invention provides a method and device for charging a battery of an extended-range hybrid vehicle and the extended-range hybrid vehicle, and the method comprises the steps: firstly determining the current state of a preset power limiting element, and determining the first power generation power of an ISG motor driven by an engine according to the current state of the preset power limiting element; then determining the residual power after the first generation power meets the vehicle electricity load, and determining the battery reference charging power based on the residual power; according to the current operation condition of the vehicle and the window range where the SOC of the battery is located, a correction coefficient which needs to be used currently is determined; and finally, correcting the reference charging power of the battery by adopting the correction coefficient to obtain the target charging power of the battery, and charging the battery. The charging efficiency is higher, reduction of oil consumption is facilitated, and energy is saved.
本公开实施例提供了增程式混动车辆电池充电方法、装置及增程式混动车辆,该方法首先确定预设功率限制要素的当前状态,并根据预设限制要素的当前状态确定发动机带动ISG电机的第一发电功率;再确定该第一发电功率满足车辆用电负载后的剩余功率,并基于该剩余功率确定电池参考充电功率;又根据车辆当前运行工况以及电池SOC所处窗口范围,确定当前应使用的修正系数;最后采用该修正系数对电池参考充电功率进行修正,得到电池目标充电功率,并对电池进行充电。本公开充电效率更高,有利于油耗降低,节约了能源。
