This topic is taught as part of our 4-year bachelor's degree program. For more information on the Weber Automotive program, visit: http://www.weber.edu/automotive In this episode, we explore the 4th generation Toyota Prius 207.2 Volt Li-Ion battery system. This system is very different from previous generations of the 2016 - 2022 Toyota Prius. This episode covers High Voltage Hybrid Electrical Systems - Specifically the 4th generation Toyota Prius 207.2 Volt Li-Ion battery system. The 2017 Prius Prime 351.5 Volt battery is also discussed. This battery is rated at 0.75kWh. 0.75kWh / 207.5V = 3.6Ah rating. The system is protected by a 125A fuse. This video was created and edited by Professor John D. Kelly at WSU. For a full biography, see http://www.weber.edu/automotive/J_Kel... QUESTIONS FOR TEACHERS: 1. What is different about the service plug grip on this battery versus previous generations of Prius batteries? 2. How is this battery cooled? 3. What is a battery stack? 4. What is the stack voltage? 5. How many battery stacks are in this battery? 6. How are the stacks wired (Series or parallel)? 7. What is the amperage rating of the battery fuse? 8. How are battery cell voltages monitored? 9. How are battery cells balanced is there is an imbalance after battery service? 10. Where is the battery current sensor located? 11. What warning is there on the battery ECU? 12. Are the sides of the battery cells dangerous to touch? 13. What parts are serviceable in the battery? 14. What was the battery state of charge when the engine shut off in the video? 15. At what battery state of charge will the engine re-start?
