Thermal analysis and pack level design of battery thermal management system with liquid cooling for electric vehicles

In this paper, a comparative study for structural design of battery thermal management system is presented for electric vehicles. A thermal model for the pouch battery pack with liquid cooling is developed for thermal analysis of various pack designs. Typical battery pack with fin-cooling structure is set as a reference design, and thermal behavior of the battery pack is examined in the aspect of cooling performance and temperature uniformity. Numerical results indicate that poor heat conductivity from the bottom of the cell stack to the cooling plate is one of the major barriers to the efficient heat dissipation and asymmetric design of fin-cell arrangement have negative effect on the temperature uniformity of the battery pack. To improve the performance of the thermal management system, various structural designs are suggested and evaluated based on plural criteria. A new structural design for the large-scale battery pack is suggested to enhance the cooling performance and temperature uniformity of the battery pack minimizing the increase in system volume, weight, and pressure drop.

Prioritas Alternatif Keputusan pada Analisis Kredit Motor

Non-performing loans are common problem faced by financing companies. One of the companies which is exposed to this problem is a motorcycle dealer. Object of this research is PT. AM, a motorcycle dealer of brand Yamaha. Corporate leaders realized the problem of non-performing credit, and they tried solving the problem by conducting strengthens analysis credit with the purpose to sustain the operational in the future. The methods used in this research were standard credit scoring and method of comparison exponential as decision-making to determine the sequence of alternative counsel by plural criteria. The technique of the data collection was directly face-to-face unstructured interview through. On the stage of standard credit scoring analysis, the data obtained process by giving value. Next on the stage analysis using method of comparison exponential, used the calculation of parameters and eckenrode method. The final results of this research were that good analysis management of credit can reduce the problem of non-performing loans. It is proven of 3 debtor non-performing in notes of the company was 3 debtor equal to the result predictions of this research.
