The invention discloses a low-voltage power supply system for an automobile. The low-voltage power supply system for the automobile comprises an overcurrent protection module and an emergency current-limiting power supply module. By arranging the overcurrent protection module and the emergency current-limiting power supply module, if the overcurrent protection module connected with one electric appliance is connected with the emergency current-limiting power supply module in parallel, when the overcurrent protection module is disconnected, the emergency current-limiting power supply module also connects the electric appliance with the power supply module, so that the electric appliance cannot immediately lose power supply of the power supply module; therefore, the electric appliance can still play the function, the function of the electric appliance with high importance such as a brake, a lighting system and the like can be prevented from being instantly and completely lost, time can be provided for a driver to dispose faults, and the driving safety of an automobile is guaranteed; the electric appliance can be prevented from immediately losing power supply of the power supply module, and sudden load change of the power supply module can also be avoided, so that the working stability of the power supply module is guaranteed, and the safety of the vehicle-mounted equipment is guaranteed. The invention is widely applied to the technical field of automobiles.

    本发明公开了一种用于汽车的低压供电系统,用于汽车的低压供电系统包括过流保护模块和应急限流供电模块。通过设置过流保护模块和应急限流供电模块,如果一个用电器所连接的过流保护模块并联了应急限流供电模块,当过流保护模块断开时,应急限流供电模块还会将该用电器与电源模块连接,使得该用电器并不会立即失去电源模块的供电,使得该用电器仍能够发挥其功能,能够避免制动器、灯光系统等重要程度高的用电器的功能瞬间完全丧失,可以为驾驶员处置故障提供时间,保障汽车驾驶安全;由于可以避免用电器立即失去电源模块的供电,也可以避免电源模块的负荷突变,有利于保障电源模块的工作稳定,保障车载设备的安全。本发明广泛应用于汽车技术领域。
