The invention relates to the technical field of electric vehicle batteries, in particular to a storage battery charging control method and device during dormancy of an electric vehicle. An automatic charging strategy is provided for the long-term standing working condition of the vehicle, it is guaranteed that the vehicle can be reliably and effectively charged under the long-term standing working condition, and reliable charging of the electric quantity of the storage battery is guaranteed; under the condition of no fault, the power supply demand of the vehicle is ensured; a PCU (Power Control Unit) is used for waking up an associated controller and entering a set intelligent charging process by utilizing an automatic starting mode of the PCU or a system clock so as to carry out automatic charging on a dormant vehicle, so that a storage battery can be timely charged when the storage battery is not used for a long time; and a fault processing strategy of the intelligent charging function is formulated, safety and reliability are achieved, and it can be effectively guaranteed that an intelligent charging program is started on the premise that the whole vehicle is safe and free of faults.

    本发明涉及电动车电池技术领域,特别涉及一种电动车休眠时蓄电池补电控制方法及装置。本发明对车辆长期处于静置状态工况下提出一种自动补电策略,保证了车辆在长时间静置工况下可以可靠有效的补电,保障了蓄电池电量的可靠补充;在没有故障的情况下,保证了车辆的供电需求;采用PCU利用自身或系统时钟自动启动的方式,唤醒关联控制器,进入既定的智能补电流程,来对休眠时的车辆进行自动补电,保证了在长时间不使用时蓄电池也可以及时补充能量;制定了智能补电功能的故障处理策略,更加安全可靠,可以有效的保证在整车安全无故障的前提下启动智能补电程序。
