Abstract

A battery is an important part of electric vehicle which is converting the chemical energy into electrical energy. There are two types of battery based on the occurrence i.e. primary and secondary batteries. In the market there are a lot of secondary battery types for electric vehicle i.e. Lithium-ion, Lithium Polymer, Lead acid, and Nickel Metalh Hydrarde batteries. Because of that, a study comparation of secondary battery types was needed. Meta-analysis method was used to analyze the comparison between secondary battery types. The results showed that each battery have different spesifications, advantages, and disadvantages. There are a lot of consideration to choose battery for electric vehicle including initial cost, life time, mass, volume, temperature sensitivity, acces to care and acces to product.

Abstract

Finite Element Analysis (FEA) is a calculation tool to find out a determined solution for a complex structure subjected to some certain static load. To obtain the most valid solution from this analysis, one of the parameters needed is mesh convergence test. This paper discusses the mesh convergence test by using FEA in a 2-kW induction motor shaft where the motor is used in an electric motorcycle. FEA was carried out by using static structural module in ANSYS 14.5 software. The shaft was subjected to static load from rotor and pulley weight. These loads were supported by a pair of ball bearing. Furthermore, the shaft was meshed by using various sizes of mesh to find out the effects to mesh convergence. The applied mesh sizes were 3; 2,5; 2; 1,5; and 1 mm. These simulation results represented the value of deformation and stress on the shaft. The convergence test was depicted in a graph of elements number vs. deformation and elements number vs. Von – Mises stress. The maximum deformation was located around rotor seat, while the minimum one was around the rear bearing seat. On the other hand, maximum and minimum Von – Mises stress appeared around rear bearing seat. Overall, it can be concluded that the results of deformation and Von – Mises stress had reached convergence
