ELECTRIC VEHICLE
First Claim
1. An electrically driven vehicle comprising:
- a lithium ion battery mounted inside a vehicle interior;
a battery state detector that detects a state of the lithium ion battery;
a gas discharge passage through which gas emitted from the lithium ion battery under abnormal conditions of the lithium ion battery is exhausted out of the vehicle interior;
a ventilation mechanism that ventilates air inside the vehicle interior; and
a controller that starts and stops the ventilation mechanism,wherein 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.

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.
