Electric Vehicle Battery Construction (cont.) Design a battery pack for an all electric vehicle assuming you have single cell specifications: Vcell = 4.2V, Capacity cell = 5.5Ah . • The battery pack should have the following specifications: Energy Pack = 60 KWh and Vpack = 400 V. (a) Specify how many series and parallel cells should meet the required specifications. (b) Assume the pack is directly connected to an electric motor with 200 KW, specify the maximum current to be drawn from every cell to satisfy the motor power. Provide the answer in terms of C-rate. (c) Assume the EV to be charged using an AC Level 1 charger (120VAC, 16 A). how long will it take to fully recharge the battery pack assuming the pack is fully discharged? (d) How long would it take if you had an AC Level 2 charging unit (220VAC, 80 A)? (e) What is the effect of selecting the charger level on the EV owner and the electric grid? 49
