Solution 1:   Test Sequence 1 Result: In test sequence 1 there are different states: Driving: During time period of 0 to 3000 sec driving condition is selected which means battery is been discharge. As a result…

Lithium ion Batteries   It was not until the early 1970s that the first non-rechargeable lithium batteries became commercially available. Attempts to develop rechargeable lithium batteries followed in the 1980s but the endeavor failed because of instabilities in the metallic lithium used as anode material. Lithium…
