ABSTRACT:
A motor controller for a battery-powered electric motor automatically disables the motor when the battery voltage (1) remains below a first, higher level for a longer time when the motor is off, or (2) remains below a second, lower level for a longer time when the motor is on, or (3) falls below a low level less than about one quarter the nominal level of the voltage for a shorter time. The motor is automatically enabled when the battery voltage rises to a higher level for a preset time period, indicative of charging of the battery.
