An electronic load capable of discharging the battery cell at a maximum current of 40A has been developed. The discharge process begins when the cell voltage exceeds 3.7V and ends when the voltage falls below 3V. The main potentiometer controls the discharge constant current, while the two trimmers control the higher/lower voltage levels at which the discharging process begins and ends. Six mosfets were used in parallel as active devices, each controlled by one of the LM393 comparators. The second comparator is used to indicate signals. Ten parallel resistors sense the current and dissipate some of the power.
