The layout of temperature sensors mainly designed for the requirement of thermal management. The acquisition of temperature rise of lithium-ion battery is to get the condition for cooling on. However, in some extreme cases, the placed temperature sensors can not detect the precursor of thermal runaway of a specific cell. The objective of this paper is to optimize the temperature sensor placement to satisfy both thermal management and thermal runaway requirement. To achieve the goal, The temperature sensors placement of lithium-ion battery module was analyzed under charging and discharging conditions for thermal management requirement. Then, the temperature distribution of battery module was studied considering thermal runaway and the optimization results of temperature sensors placement was given. The temperature signal of the cell experiencing thermal runaway can be detected by the neighboring cell. In order to satisfy the requirement for thermal management and thermal runaway, one temperature sensor is placed every two cells on the middle part of the cell and two temperature sensors are placed on the upper part of the side cells.
