The invention relates to the technical field of electric vehicles, and discloses an electric vehicle low-voltage system control method, device and equipment and a storage medium. In the invention, a key gear state of an electric vehicle can be obtained, and when the key gear state is in an ON gear state, a direct-current converter is controlled to enter a starting state; according to the invention, the state of charge of the storage battery is determined according to the storage battery information, and when the state of charge of the storage battery is less than or equal to the preset state of charge, the direct-current converter is controlled to supply power to the whole vehicle low-voltage system of the electric vehicle, thereby avoiding power shortage of the storage battery and improving the working efficiency of the direct-current controller. And the power supply of the whole vehicle low-voltage system can be effectively controlled by combining the state of the storage battery andthe actual demand of the whole vehicle low-voltage system.
本发明涉及电动汽车技术领域,公开了一种电动汽车低压系统控制方法、装置、设备及存储介质,在本发明中,可获取电动汽车的钥匙档位状态,在钥匙档位状态处于ON档状态时,控制直流变换器进入开机状态,根据蓄电池信息确定蓄电池荷电状态,并且在蓄电池荷电状态小于等于预设荷电状态时,控制直流变换器为所述电动汽车的整车低压系统供电,从而既可避免蓄电池亏电,又可提升直流控制器工作效率,可结合蓄电池状态以及整车低压系统实际需求对整车低压系统的供电进行有效控制。
