,Parameters to be considered
• Costs per kWh
• Specific Energy density (Wh/kg)
• Vol. Energy density (Wh/litre)
• Life-cycles at certain C-rate and temperature at certain DoD
• Capacity and DoD usable
• C-rate usable
• Safety and safe-disposal
, Slow Charging vs Fast Charging
• Depends on the C - rate of the Battery
• C- rate is the rate at which battery is charged/ Discharged
• Battery capacity and Charger ratings
• Charging at 1C and higher (1.5C, 2C, 3C, 4C) is fast Charging
• Charging at 0.5C and lesser (0.1C, 0.2C, 0.3C, 0.4C) is slow Charging
Ratings C - rate Time taken to
