An intelligent electric vehicle (EV) rapid-charging station uses a local microcontroller to manage a charging session. The vehicle's maximum battery capacity (in kWh), the current state of charge (as a percentage), and the user's payment identification token are already stored as variables within the program.
State two other physical measurements or session parameters that would need to be stored as variables or constants to manage the charging process.
