Abstract
An enclosed battery emissions dilution and sampling system includes a heated exhaust tube, an enclosure defining at least one inlet port on one end of the enclosure and an outlet port on another end of the enclosure fed into the heated exhaust tube, a dilution air line, at least one heated inlet line arranged with an end of the dilution air line and fed into the at least one inlet port, and a bypass line connected between the dilution air line and heated exhaust tube, and around the enclosure.
Claims7
An enclosed battery emissions dilution and sampling system comprising:
- a heated exhaust tube;
- an enclosure, configured to completely contain a battery, defining at least one inlet port on one end of the enclosure and an outlet port on another end of the enclosure fed into the heated exhaust tube;
- a dilution air line;
- at least one heated inlet line arranged at an end of the dilution air line and fed into the at least one inlet port;
- a bypass line connected between the dilution air line and heated exhaust tube, and around the enclosure;
- a pump arranged to operate such that (i) a portion of dilution air from the dilution air line flows through the at least one heated inlet line and enclosure over the battery to entrain emissions from the battery therein, creating diluted sample gas, and into the outlet port, and another portion of the dilution air flows through the bypass line around the enclosure and (ii) the diluted sample gas and another portion of the dilution air mixes within the heated exhaust tube;
- and
- a controller programmed to calculate a mass flow rate of the emissions as a difference of a mass flow rate through the heated exhaust tube and a mass flow rate through the dilution air line.
