The inevitable non-uniform temperature distribution across a large number of thermoelectric modules can cause reduced output power of the automotive exhaust thermoelectric generator (AETEG). In order to achieve accurate tracking of maximum power point for an AETEG, a distributed thermo-electric energy recovery system is proposed consisting of sever...

... SOC t0 is the initial SOC at time t 0 . V oc , R int , P bat , I bat , and Q b are the OCV, internal resistance, output power, output current, and the capacity of the battery pack, respectively ( Li et al., 2018). The OCV and the internal resistance are expressed as functions of the SOC as shown in Fig. 4. In Fig. 4, R int is R dis for the discharging process, while being R chg for the charging process. Here, the internal resistance of the battery is assumed not affected by the temperature change and battery degradation for ...

Particulate filters are used to meet current and future emission-control standards for particle mass and particle number requirements. However, with vehicle operation, non-combustible material (termed as "ash") collects in the filter leading to an increase in ∆P, lower fuel economy, reduced soot storage space, and lower conversion rates for exhaust...
