Electric vehicle
First Claim
1. An electrically driven vehicle, comprising:
- a battery mounted inside a vehicle interior;
an air intake duct which is provided with a cooling fan, and which is adapted to provide the battery with cooling air from the vehicle interior;
an air discharge duct arranged to discharge, into the vehicle interior, air which was warmed after cooling the battery;
a battery state detector that detects a state of the battery;
a ventilation mechanism which comprises an outside air introduction mechanism that introduces outside air into the vehicle interior, and which ventilates air inside the vehicle interior; and
a controller that starts and stops the ventilation mechanism,characterized in that;
the battery is a lithium ion battery;
the electrically driven vehicle comprises a gas discharge passage through which gas emitted from the lithium ion battery under abnormal conditions of the lithium ion battery is discharged into the vehicle interior;
the ventilation mechanism comprises a window glass drive mechanism that moves a window glass in the vehicle interior;
the controller includes a ventilation mechanism starting means that starts the ventilation mechanism when the lithium ion battery is determined to be in an abnormal state when a value showing the state of the lithium ion battery detected by the battery state detector exceeds a predetermined threshold, said ventilation mechanism starting means comprising an outside air introduction starting means and a window opening starting means that starts opening of the window glass by the window glass drive mechanism; and
the battery state detector is any one of or a combination of any one of;
a voltage sensor installed in the lithium ion battery,a temperature sensor installed in the lithium ion battery,a gas sensor installed in the gas discharge passage, anda gas temperature sensor installed in the gas discharge passage.

Abstract
An electric vehicle is provided with a cell voltage sensor (32) and a cell temperature sensor (31) which are mounted to each of a plurality of cells (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.
