Problem 1 (20 points) In below, the left figure is a lithium-ion battery's discharging curve under different C-rates at the temperature of 23°C. The right figure is the discharging curve at the different temperatures under 0.5C-rate. The battery's energy rating is 1500mAh and discharging cut off voltage is 3.4V in operation. Please calculate 1) how much energy and how long time the battery could be discharged under different C-rates at the temperature 23°C. 2) how much energy and how long time could the battery be discharged for the battery under 0.5C rate at the different temperatures? VOLTAGE(V) 4.2 4.0 2.0C 1.0C 0.5C 0.2C 3.8 3.6 3.4 3.2 3.0 0 400 800 CAPACITY (mAh) VOLTAGE(V) 4.2 -20°C -10°C 0°C 23°C 45°C 4.0 3.8 3.6 3.4 3.2 3.0 1200 1600 2000 0 400 800 1200 1600 2000 CAPACITY(mAh)
