MOBILE OBJECT WITH BUILT-IN SECONDARY BATTERIES AND GAS TREATMENT DEVICE FOR SECONDARY BATTERIES

摘要

A mobile object with built-in secondary batteries and a gas treatment device for secondary batteries in which even if one secondary battery module generates heat, the heat can be prevented from being transmitted to another secondary battery. The mobile object with built-in secondary batteries comprises a vehicle body which includes an exhaust port, a first duct which, when secondary battery modules respectively including ejection ports for ejecting gas are built in, causes the ejection ports to communicate with the exhaust port, a second duct which is provided in the vehicle body and communicates with the outside, and an air current generating mean for generating an air stream in the second duct by a gas stream flowing in the first duct. The air current generating section generates the air current in the second duct by the gas stream when gas is ejected from the secondary battery module into the first duct.
