An electric vehicle comprises essential components like Motor, Gearbox, Motor Controller, and Battery Pack. The Lithium Ion Battery Pack should operate within a certain temperature range, for example, 20 to 40 deg. Celsius for longevity of life. Thus there is a need of thermal management system which can cool the battery pack in hot climate and heat the battery pack in extremely cold climates so that optimum temperature is maintained. Temperature of Motor, Motor Controller & Gearbox must be maintained above ambient and the temperature of the Battery Pack must be maintained below the ambient air temperature. Question A: Design a thermal management system which can provide cooling of Motor, Gearbox & Motor Controller and provide both cooling and heating of Battery Pack. You can use the optional components provided in the diagram below. There is no limit on quantity of optional components to be used, except for the radiator, only one radiator can be used. The goal is to design effective and compact thermal system. You are supposed to draw a schematic diagram using essential and optional components. The Motor, Motor Controller & Battery Pack are water cooled while the Gearbox is oil cooled. Coolant Inlets and outlets are mentioned in the diagram. Heat Exchanger is a liquid to liquid heat exchanger. Question B: Justify the sequence of components in respective thermal loops in previous answer.

6. Mechanical Draw and fully constrain the view shown. Follow the guidelines below. Infer constraints when possible and appropriate. Use the Fillet option of the RECTANGLE command to create the 4.6250 by 6.3750 rectangle with .6250 rounded corners. Use the RECTANGLE command to create the construction rectangle and then add the circles. Notice that the circles are not concentric to the arcs. Apply geometric constraints in the following order: fix the center of the lower-left circle; make all circles equal; make all arcs equal. Use the AUTOCONSTRAIN command with default settings to apply the remaining geometric constraints. Edit the d1 parameter to change the distance to 1.0000. Edit the d5 parameter to change the distance to 5.1250. Save the drawing as P22-6.
