The invention discloses an energy management method for low-voltage power distribution of an intelligent rail tramcar and a low-voltage power distribution system, and the method comprises the steps: 1, judging whether normalizing is activated or not, and if yes, controlling the power distribution system to be electrically connected with a first type of load, so as to enable a storage battery pack to supply power to the power distribution system; 2, judging whether the low voltage is activated or not, if so, controlling the power distribution system to establish electric connection with the first type of load and the second type of load at the same time to supply power to the power distribution system through the storage battery pack, and if not, recording the low voltage inactivation time; when the low-voltage non-activation time reaches a first preset time threshold value, the electric connection between the power distribution system and the first type of load having low correlation with the operation of the electric vehicle is cut off; and 3, judging whether the high voltage is activated or not, and if so, controlling the power distribution system to establish electric connection with the first-class load and the second-class load, so that the auxiliary power supply supplies power to the power distribution system. The energy loss of the storage battery pack can be reduced, and the vehicle safety is ensured.

    本发明公开了一种用于智轨电车低压配电的能量管理方法及低压配电系统,包括:步骤一、判断常火是否激活,若激活,则控制配电系统与第一类负载建立电连接,使得通过蓄电池组为配电系统供电;步骤二、判断低压是否激活,若激活,则控制配电系统同时与第一类负载和第二类负载建立电连接,使得通过蓄电池组为配电系统供电,若未激活,则记录低压未激活时间,从而在低压未激活时间达到第一预设时间阈值时切断配电系统与跟电车运行具有低相关性的第一类负载之间的电连接;步骤三、判断高压是否激活,若激活,则控制配电系统与第一类负载和第二类负载建立电连接,使得通过辅助电源为配电系统供电。本发明能降低蓄电池组的能量损耗,保证车辆安全。
