The vehicle is targeted to meet the following imperatives: range of 400 miles acceleration from 0-60mph of 4.5 second in addition, a base model is being considered for lower cost (cost is more important than mass optimization so lower performing battery cell chemistries such as LFP are to be considered) Your goal is to develop the pack design. Key steps for the group are to: 1. Compare at least 2 designs; 1 for premium model and 1 design for base model by selecting different cell types (cylindrical, pouch, prismatic). Use cell data from previous lectures or do internet searches to choose a different cell. Determine series cell count and parallel cell count from the previous lectures of available cells, based on: a. usable energy requirements (hint: from range req) b. voltage range (hint: from powertrain system req) c. power requirements d. life requirements e. mass and volume requirements f. in the final report, explain how the series/parallel count was determined and what oversizing factors were considered 2. Develop rough packaging based on cell type with appropriate cell spacing or support components (i.e. expansion pads) 3. Determine DCFC (DC Fast Charge) power requirement from requirement 4. Suggest safety features for pack 5. Develop a ROM (rough order of magnitude) BOM (bill-of-materials) grouped by the major subsystems discussed. Assign estimated masses for each item. 6. You will be able to use data collected from the lectures, internet or other. 7. The design will have to be depicted in a professional PowerPoint slide (no more than 16 slides) and write a report in Word (no more than 10 pages). Both documents should be first converted to PDF before uploading it to BrightSpace. The following vehicle requirements apply: 8. 150,000 mile design life on EPA drive-cycle 9. 400 miles per charge (EPA drive-cycle) for premium model a. 250 miles per charge for lower cost base model 10. 250 Wh/mile powertrain simulation for EPA drive-cycle 11.90% drive-cycle is 50 kW rms; 10% is 10 kW rms 12. 250 kW of 10-second discharge power 21:23 ?
