Abstract

The present invention relates to a battery module which can be used safely even if mounted in moving bodies such as electric cars and deep sea exploration vehicles. The battery module (10) comprises unit batteries (13) and a unit battery container (14) for containing the unit batteries (13). The unit battery container (14) comprises an upper housing (18) forming a lid body and also comprises a lower housing (19) in which the unit batteries (13) are arranged. The lower housing (19) has through-holes formed running through the thickness direction at the positions corresponding to the centers of the lower surfaces of the unit batteries (13). Branch tubes (23) are connected to the through-holes. The branch tubes (23) are connected to a single main tube (25) equipped with a liquid leakage sensor (24) at one end of the main tube. The liquid leakage sensor (24) is connected to a liquid leakage detecting device (27) via a signal cable (26).

Description

technical field [0001] The present invention relates to a battery pack, and in particular to a battery pack suitable for being mounted on a mobile body such as an electric vehicle or a deep-sea probe. Background technique [0002] In general, when lithium batteries, fuel cells, etc. are used for various applications, it is required to ensure the reliability and safety of these batteries. In particular, when the above-mentioned battery is used in a mobile body such as an electric vehicle or a deep-sea probe, it is necessary to confirm that the above-mentioned battery satisfies predetermined standards through tests such as a drop test, a vibration test, and an impact test. [0003] Moreover, if a short circuit occurs in the electrodes while the battery is being charged, heat will be generated inside the battery due to the internal short circuit current, which may cause high-temperature gas to be ejected and cause damage to the battery, and the electrolyte in the battery may le...
