摘要： A system, method, and apparatus are provided for estimating a flux of fugitive gas emissions. The method is performed using a gas analyzer coupled to a sampling wand, where gas enters the inlet tip of the sampling wand prior to being sampled by the gas analyzer. The sampling wand is fixed to a mobile device that includes an inertial measurement unit. Location information from the inertial measurement unit is used to compile a high resolution geo-spatial map of gas concentration levels across a cross-sectional area of a gas plume. A near-field Gaussian plume inversion calculation is then performed to estimate the flux based on the gas concentration data and the location information.

摘要： A vehicle and an airtightness detection method for a battery pack (1) thereof, belonging to the technical field of battery pack (1) safety. A detection port and an air inlet are arranged on the battery pack (1) of the vehicle. An air pressure detector (12) is arranged at the detection port to detect an air pressure inside the battery pack (1). The air inlet is connected to an air source (3) by an air pipeline (6). A solenoid valve (5) is arranged on the air pipeline (6). A system controller (2) controls inflation of the battery pack (1) by controlling on/off of the solenoid valve (5). During airtightness detection, the battery pack (1) is inflated so that an internal pressure thereof is greater than the atmospheric pressure. After the inflation is completed, the air pressure inside the battery pack (1) is acquired, and the airtightness of the battery pack (1) is determined according to a variation of the air pressure. The airtightness of the power battery pack (1) is detected by using the on-board apparatus, and the level of protection of the power battery pack (1) is monitored in real time during a vehicle lifecycle. In addition, the remote warning for the vehicle can be realized according to a monitoring result through a remote data center (8), which reduces the potential safety hazards for the vehicle.
