2017 Chevrolet Bolt EV 350.4V Li-Ion Battery Reassembly - A Youtube first!

Weber State University (WSU) - Department of Automotive Technology - Ardell Brown Technology Wing - Transmission Lab.

This is the third is a series of videos on the Chevrolet Bolt EV. This episode covers the reassembly of the 57 kWh 350.4 volt 162.7 Ah battery from a 2017 Chevrolet Bolt EV. The components are shown and operation will be similar to many other electric vehicles.

This video helps cover content related to the 2017 National Automotive Technicians Education Foundation (NATEF) Master Automobile Service Technology (MAST) Standard task 1.A.9 "Identify service precautions related to service of the internal combustion engine of a hybrid vehicle."

W.S.U is a leader in Hybrid and Electric Vehicle education. This topic is taught as part of our 4-year bachelor's degree program. For information on joining the Weber Automotive program, visit: http://www.weber.edu/automotive

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...

Watch the video from the start until time frame 22.38 and answer the following questions:
1. What is the purpose of the battery tray inspection plug?
2. How many cooling plates are there?
3. How many coolant transfer hoses are there at the back of the battery?
4. Why are the battery thermal mats covered with plastic?
5. What is the purpose of the black pads at the bottom of the battery housing
6. How are the battery sections connected to the thermal mats?
