Embodiment Construction

[0018] Below, while referring to the attached Figure 1 Preferred embodiments of the present invention will be described. Such as figure 1 As shown, the electric vehicle 100 of this embodiment includes a vehicle body 10 and a cabin 11 partitioned by a front partition member 12 and a rear partition member 13 inside the vehicle body 10 . An engine (not shown), a motor generator for driving the vehicle, a power distribution mechanism, an inverter, driving gears, and the like are accommodated in an engine hood located in front of the front partition member 12 . A door 40 having a window glass 41 is attached to the vehicle body 10 in a freely openable and closable manner. The window glass 41 is opened and closed up and down by a driving motor and gears not shown. The driving motor and the gear constitute a window glass driving mechanism.

[0019] Under the hood in front of the front partition member 12 is provided an air conditioning fan 17 that sends air to the passenger compa...

Abstract

An electric vehicle is provided with a cell voltage sensor (32) and a cell temperature sensor (31) which are mounted to each cell (21); a gas temperature sensor (33), a carbon monoxide gas sensor (34), and a hydrogen gas sensor (35) which are mounted to a chamber (27); a gas temperature sensor (36), a carbon monoxide gas sensor (37), and a hydrogen gas sensor (38) which are mounted to a gas exhaust passage (28); and an air-conditioning fan (17), a channel-switching damper (19), and a driving motor (42) which lowers a window glass (41). When battery state values detected by the sensors (31) to(38) exceed predetermined thresholds, a battery pack (20) is judged to be abnormal. Then, the channel-switching damper (19) and the air-conditioning fan (17) are started and the window glass (41) is lowered to ventilate the vehicle interior. This speedily exhausts smoke generated from a lithium ion battery.

Description

technical field [0001] The present invention relates to the structure of an electric vehicle equipped with a lithium ion battery. Background technique [0002] In recent years, electric vehicles such as hybrid vehicles, fuel cell vehicles, and electric vehicles that run with driving force from electric motors have attracted attention as one of countermeasures against environmental problems. Such electric vehicles are equipped with secondary batteries such as batteries. A nickel-hydrogen battery, a lead storage battery, or the like is used as a secondary battery constituting a power source for driving the vehicle. [0003] A secondary battery for driving a vehicle is often installed in a vehicle compartment to be cooled by air-conditioned air in the vehicle compartment. In particular, in order to effectively use the capability of the air conditioner for the interior of the vehicle, the air in the interior of the vehicle is sent to the secondary battery to cool the secondary...
