“…The estimation of states and unknown inputs (UIs) is important in fault diagnosis and dynamic system control. [1][2][3][4][5] This problem is frequently encountered in power system exciters, [6,7] chemical processes, [8][9][10] state estimation of a battery, [11][12][13] navigation, [14,15] and earthquake damage estimation. [16] Over the last decade, many methods have been proposed for the simultaneous estimation of the UIs and states in a linear discrete-time system, [17][18][19][20][21][22] among which Gillijns and De Moor [22] present a valuable overview.…”

In this study, the simultaneous estimation of the states and unknown inputs for a nonlinear multi-agent system with homologous and heterogeneous unknown inputs is performed. The decentralized sub-filter is used to estimate the states and heterogeneous unknown inputs, whereas the distributed subfilter is used to estimate the homologous unknown inputs. The extended Kalman filter is used to solve the estimation problem for nonlinear systems. Compared with previous studies, the distributed solution is improved to relax the existence of the homologous unknown input sub-filter. Moreover, the updating method of the residual generator is improved to relax the heterogeneous unknown input sub-filter. The practical problem of estimating the state of charge and temperature of the battery pack is used to verify the effectiveness of the proposed filter.

“…And as the main energy source of EVs, power battery is an important indicator to evaluate the performance of a whole vehicle. However, the performance of the power battery is significantly affected by temperature; previous studies have shown that the efficient operating temperature of the battery does not exceed 45°C and the local temperature difference should be controlled within 5°C. Feng et al proved that the battery capacity will be reduced by more than 20% under 120°C.…”

Summary The performance of power battery is a significant factor affecting the overall quality of electric vehicles. To optimize the thermal management effect of battery pack, cold plate with wedge‐shaped microchannels was proposed in this paper. On the basis of the models of the independent cold plate and the battery‐cooling module, the effects of outlet aspect ratio, flow rate, and branching structure on the heat dissipation performance of the cold plate were studied at first. Afterwards, the effects of cooling surface, flow rate, and branching structure on the temperature distribution of the battery module were simulated. The results showed that the wedge‐shaped channels provided a good cooling efficiency and surface temperature uniformity. When the wedge‐shaped channel was used in thermal management of the battery module, the side‐cooling method reduced the temperature difference of batteries by more than 35.71% compared with front cooling under the mass flow rate of 2 × 10−5 kg/s. At a discharge rate of 3.5 C, the flow rate of 1 × 10−4 kg/s controlled the battery temperature to within 45°C, and the branching structure designed for the module successfully decreased the maximum temperature difference from 7.27°C to 4.67°C, which has been reduced by approximately 35.78%.

Influence of atomization conditions on spray drying lithium iron phosphate nanoparticle suspensions

Removing solvents from nanoparticle solid suspensions requires the same diligence as drying pharmaceutical ingredients. LiFePO 4 nanoparticles suspension in water oxidize, sinter, and Li 3 PO 4 segregates on the surface when they dry in a furnace. Spray drying preserves the material properties because contact times are on the orders of seconds; furthermore, the atomized droplets ensure particles are small (5 m to 20 m) and dispersed. A Yamato GA-32 (120 mm inner diameter) spray dried in co-current flow a nanoparticle suspension of LiFePO 4 in water, with a solid content up to 60 %. Atomization gas velocities of 140 m s −1 to 350 m s −1 agglomerated the nanomaterial into spherical particles that ranged from 3 m to 10 m. The particle diameters ranged from 10 m to 20 m at atomization velocities of 50 m s −1 to 140 m s −1 . At this condition, yield was lower because the semi-dried particles adhere on the wall. At 150 • C to 200 • C the surface area reached 26 m 2 g −1 while from 50 • C to 100 • C it varied from 14 m 2 g −1 to 20 m 2 g −1 . The trend for mesoporosity versus spray drying temperature is the same as for surface area: pore volumes are higher (0.18 cm 3 g −1 ) above 200 • C and 20 % lower below 200 • C. Drying temperature modifies drying speed; low temperatures compact the powders more than high temperature which results in lower surface area and porosity. Figure 13.
