The invention provides a whole vehicle energy management method and device, a storage medium and equipment, in the method, under a charging heating working condition or a driving recovery heating working condition, a closing delay request is sent to a heat management controller, so that the heat management controller can control the closing delay request when downshifting or closing active heating is needed after a target heating requirement is met; the method comprises the following steps of: postponing to close an electric drive active heating function, when a closing delay state signal fed back by a heat management controller is received, rejecting electric drive active heating consumed power from an energy management algorithm so as to adjust charging current management or electric drive torque management, and then sending an immediate closing request to the heat management controller; therefore, the heat management controller closes the electrically-driven active heating function. Therefore, intelligent management of vehicle high-voltage accessory energy is realized, the overcharge risk of the power battery is reduced, the service life of the battery is prolonged, and the safety of the whole vehicle is improved.

    本申请提供一种整车能量管理方法、装置、存储介质及设备,该方法中,在充电加热工况或行车回收加热工况下,向热管理控制器发送关闭延迟请求,以使热管理控制器在达到目标加热需求后需要降挡或关闭主动加热时,暂缓关闭电驱主动加热功能,在接收到热管理控制器反馈的关闭延迟状态信号时,从能量管理算法中剔除电驱主动加热消耗功率,以此调整充电电流管理或电驱扭矩管理,之后向热管理控制器发送立即关闭请求,以使热管理控制器关闭电驱主动加热功能。这样,实现对车辆高压附件能量的智能管理,降低动力电池过充风险,延长电池寿命,提升整车安全性。
