Abstract

Taking lithium titanate battery as the research object, the internal resistance of starting battery was studied. Effects of four stresses on DC internal resistance of battery were investigated and discussed based on the battery test system, which were charging rate, discharge rate, state of capacity and temperature, respectively. The results show that the increase of charge/discharge rate leads to the reduction of DC internal resistance when the battery SOC is in the range of 0~90%, but these DC internal resistance values are close. The DC internal resistance is greatly affected by the temperature, the smaller DC internal resistance appears at the higher temperature. The DC internal resistance values of 0~90% SOC can be used in the process of starting power supply design for simulation processing.
