Questions 1-4 relate to a battery pack for the Tesla Roadster EV consisting of 6,831 small cylindrical lithium-ion cells (18650 format).  The battery pack has series-parallel arrangement: of 99 cells in series, and 69 strings (series-connected string) in parallel.

 

Assume this battery pack is fabricated from LG 18650 cells and  the LG CHEM 18650 Cell Specifications are:

  • Nominal Voltage: 3.7V
  • Capacity: 2800mAh
  • Max Discharging current: 5A (continuous)
  • Size: 18650 (Cylindrical)
  • Length: 65 mm
  • Diameter: 18 mm
  • Weight: 46.5 g
  • Retail Cost: $15.50.
  • What is the specific energy of each cell (Wh/kg)?

 

Q2.   What is the battery pack voltage (OCV)?

 

Q 3. What is the battery pack capacity (Ah)?

Q4.What is the battery pack energy (kWh)?
