The invention discloses an automobile storage battery fault early warning device which comprises a control module, a voltage detecting module, a power supply managing module, a power key module, a voltage display module, a sound alarm module and a state indicating module. The control module collects and stores a standard voltage curve of a storage battery through the voltage detecting module in a learning mode. The control module compares a voltage curve collected by the voltage detecting module with the standard voltage curve and judges whether faults happen or not in a working mode. When the storage battery fails, the voltage display module displays the voltage, and meanwhile the sound alarm module gives an alarm. The state indicating module indicates whether the device is turned on or not. The power key module makes the control module switched between the learning mode and the working mode. The power supply managing module supplies power to all the modules. In this way, people can find the performance abnormity of the storage battery as early as possible and be prompted, and the automobile storage battery fault early warning device is convenient to install, small in size and low in power consumption.
