The charge and discharge rates of electric vehicle (EV) battery cells affect the vehicle's range and performance. Measured in C-rates, these crucial variables quantify how quickly batteries charge or discharge relative to their maximum capacity.. This article discusses C-rate parameters, compares charge and discharge rates, and highlights the implications for EV …

Condensate flow rates for ships where steam requirement data was unavailable were interpolated based on the ship's size and similarities to other ship classes. Based upon the calculations presented in Table 2 for an average air temperature of 50 F, the average steam condensate flow rate for all ship classes is 4,500 gallons per day per ship.

In other words, the battery's average discharge rate equates to approximately a C/5 to C/10 rate, based on an average speed of 50 miles per hour. However, for LMBs, fast discharge rates (around 1C to 3C) are beneficial but unrealistic for EV applications, where discharging time typically ranges from 20 min to 1 h.
