Abstract

This paper studies on the performance of lithium-ion batteries at different temperatures. The charging and discharging and EIS experiments were carried out to explain the poor performance of the batteries at low temperatures. Experimental results show that as the decrease of the temperatures, the voltage of the battery reached the cut-off voltage rapidly and internal resistance of battery increases apparently, especially polarization resistance. Moreover, voltage platform of discharge drops, performance of high discharge rate is seriously deteriorated. The capacity and impedance of lithium ion batteries are not recoverable by low temperature charging. Thus, electric cars should not be used at low temperatures and preheated before starting at cold winter.
