The invention discloses an automobile starting circuit characteristic acquisition method and system, and a starting loop comprises a storage battery and a starter which form a loop. The automobile starting circuit characteristic acquisition method comprises the following steps: when a starter drags an engine to operate, continuously acquiring multiple groups of data of at least one voltage signal in a starting loop and a current signal of the starting loop; performing data processing on multiple groups of data of the acquired voltage signals and current signals to obtain circuit characteristics of the starting loop; wherein the circuit characteristics comprise at least one of the characteristics of the storage battery, the wiring harness characteristics of the starting loop and the dragging rotating speed of the starter. By analyzing the circuit characteristics, the normal work of a starting loop can be ensured, the design of a starting system is optimized, the energy efficiency of electric energy is improved, and more efficient and safer automobile starting is realized.
