Traction battery

Example

• Cylindrical cell Sony Lithium Ion 26650 3.7 V, 2600 mAh
• Maximum continuous discharge current: 10C, ie 10 * 2.6 = 26 A
• Maximum short-term discharge current: 20C, ie 20 * 2.6 = 52 A
• Maximum charging current: 1C, ie 2.6 A ... significant reduction of recuperation.

• Energy density:
• 3,7 * 2600 / 100 = 9,62 Wh (88 g)
• 9,62 / 0,088 = 109,3 Wh/kg

• Power density:
• 10C: I_max = 10 * 2,6 = 26 A
• P_max = 26*3,7 = 96,2 W
• 96,2 / 0,088 = 1,09 kW/kg
