The invention discloses a new energy automobile low-voltage power supply system without a low-voltage storage battery and an automobile. The system comprises a power management module and a DCDC module, and the output end of a vehicle-mounted power battery is connected to the input end of the DCDC module and the output end of the power management module; the output end of the DCDC module and the output end of the power management module are respectively led out of low-voltage power supply terminals for outputting low-voltage power supply; and the power supply management module is used for outputting low-voltage power supply when the DCDC module is in a dormant state and a standby state. The low-voltage power supply circuit has the advantages that low-voltage power supply is carried out through the designed circuit after a low-voltage 12V storage battery is cancelled, the circuit is simple and reliable, the cost is low, output low-voltage 12V power supply is more stable, reliable and stable low-voltage power supply in the two states of starting and dormancy of the vehicle can be met, the low-voltage power utilization requirement of the vehicle is met, and due to the fact that the storage battery is cancelled, the cost is low. Cost is lower, stability, reliability and safety are higher, and space in a vehicle is saved.

    本发明公开了一种取消低压蓄电池的新能源汽车低压供电系统及汽车,其中系统包括电源管理模块和DCDC模块,车载的动力电池的输出端分别连接至DCDC模块的输入端和电源管理模块的输出端;所述DCDC模块的输出端、电源管理模块的输出端分别引出低压供电端子,用于输出低压供电;所述电源管理模块用于在DCDC模块处于休眠、待机状态时输出低压供电。本发明的优点在于:取消低压12V蓄电池后通过设计的电路进行低压供电,具备电路简单可靠、成本低的优点,且输出低压12V供电更稳定,可以满足车辆启动和休眠两种状态的可靠稳定低压供电,满足了车辆的低压用电需求,由于取消了蓄电池,成本更低且更加稳定可靠和安全,且节省了车内的空间。
