Problems solved by technology

In addition, there is a need to provide a way to install the temperature sensor to be more closely attached to the battery stack for accurate temperature measurement without deviating from the existing battery module structure as much as possible to prevent loss of energy density or due to the installation of the temperature sensor. A solution that leads to a reduction in the productivity of the battery module

Abstract

Disclosed is a battery module which according to one embodiment of the present invention comprises: a cell stack formed by stacking a plurality of battery cells; a bus bar frame assembly comprising bus bar frames, which cover the two lengthwise sides of the cell stack, and a plurality of bus bars fixed on the bus bar frames and electrically connected to the battery cells; and an FPCB assembly which comprises a first FPCB extending in the length direction of the cell stack and covering at least a part of the top surface of the cell stack, second FPCBs extending from the ends of the two lengthwise sides of the first FPCB and electrically connected to the bus bars, and a pair of temperature sensors mounted at the ends of the two lengthwise sides of the first FPCB.

Description

technical field [0001] The present disclosure relates to a battery module having a structure allowing accurate temperature sensing, and a battery pack and a vehicle including the battery module, and more particularly, to a battery module in which temperature sensors are installed at both ends in the length direction of the battery stack. A sensor to allow accurate temperature sensing when sensing the temperature of a battery stack including battery cells having a length greater than width, a battery module having a structure allowing accurate temperature sensing, and a battery pack and a vehicle including the battery module. [0002] This application claims priority from Korean Patent Application No. 10-2018-0169966 filed in Korea on December 26, 2018, the entire disclosure of which is hereby incorporated by reference. Background technique [0003] It is important to accurately measure the temperature of the battery cells located inside the battery. In particular, it is nec...
