Model Screenshot : Discussion of Model and Steps : As in the challenge, we have to simulate generic battery model using UDDS data which gives us reference speed, but the problem in this is that UDDS is a drive cycle which is used for testing of vehicles (emissions, efficiency, etc....) and thus this data is speed vs time.…

Discussion of Model : Steps : For this model, I started with a blank model in simulink. Then, I imported UDDS excel data in the command window through 'Import' button in matlab variable workspace of home window. Then, I selected that excel file and selected option of impart as 'numeric matrix'. The, UDDS data…

In coulomb counting method, we continuously count the charge which has left or entered the cell to keep track of remaining charge. This is done through instantaneous measurements of current and time. It can be understood by analogy of water entering/leaving a tank. If water enters/leaves tank at the speed of y cu. metre/second…

We can understood this through an illustration. Let's assume a connection of cells with weakest cell as labelled below in the electrical coonection diagram of a battery pack Now, since it is the weakest cell it will reach cut-off voltage earliest. Thus, as soon as it reaches cut-off voltage , no more current can flow in…

The thermal management system for an electric battery back can be of following types : Air Cooling Fin Cooling Phase Change Material Cooling Direct Liquid Cooling Indirect Liquid Cooling Discussing each cooling type point wise: 1.

The battery pack to be constructed is of 18 KWh. This kind of pack is generally used in small range electric car. We can take the example of Tata Tigor EV to make assumptions, since it has battery pack 21.5 KWh, which is nearly the same specification. Tata Tigor EV is driven by 3 phase 72 V induction motor. Thus, we can…

In this project, we will analyze the effect of temperature, charge and discharge rate on life cycle performance of a lithium ion cell. For, the purpose of analysis of a 10 series cell battery pack, we can use 3.3V 6000mAh LFP type lithium-ion cell which is a popular choice in India among low power electric vehicles. First,…
