Abstract
Method and apparatus are disclosed for detecting and mitigating vehicle battery gas emission into the vehicle cabin. An example vehicle includes a battery, a vent tube coupled to the battery for venting gas outside a vehicle cabin, a gas flow sensor for determining a measured flow rate at an end of the vent tube opposite the battery, and a processor. The processor is configured for determining an expected flow rate range based on a battery characteristic, and responsive to determining that the measured flow rate is outside the expected flow rate range, initiating a protective action.
Claims20
A vehicle comprising:
- a battery;
- a vent tube coupled to the battery for venting gas outside a vehicle cabin;
- a gas flow sensor for determining a measured flow rate of the vent tube;
- and
- a processor for:
- determining an expected flow rate range based on a battery characteristic;
- and
- while the battery is operating, responsive to determining that the measured flow rate is outside the expected flow rate range, stopping battery charging or discharging operations.
A method comprising:
- determining, by a gas flow sensor, a measured flow rate of gas emitted by a battery, wherein the gas flow sensor is positioned at a first end of a vent tube opposite a second end of the vent tube coupled to the battery, and wherein the vent tube is configured to vent the gas outside a vehicle cabin;
- determining an expected flow rate range based on a battery characteristic;
- and
- while the battery is operating, responsive to determining that the measured flow rate is outside the expected flow rate range, stopping battery charging or discharging operations.
