Abstract:

Temperature sensitivity statistics were collected and analyzed for lithium-ion battery (LIB) of electric
vehicles (EV) based on survey of papers and patents. The results show that low and high temperatures have
great effect on the performances, respectively, severely affecting the operation and the market penetration of
EVs. To mitigate this problem, some techniques are used including changing raw material properties, optimizing
cell designs, and using battery thermal management systems (BTMS). Further research for temperature
sensitivity is to improve the cathode materials and anode materials of LIB to increase electric conductivities
and ionic conductivities; to optimize electrode structures and cell structures to uniform thermal and electrical
distribution; to develop new protocols for alternating current (AC) preheating/charging at low temperatures; and
to incorporate the liquid cooling method.

Key words: electric vehicle (EV), lithium-ion battery, battery system, temperature sensitivity, battery thermal management system (BTMS), charge protocol
