ABSTRACT:
An electronic device for monitoring the charge state of a rechargeable battery comprising a voltage sensor, a current sensor, a microprocessor, and a display. The voltage sensor is operatively connected to the microprocessor to provide to the microprocessor an electronic signal indicative of the voltage appearing across the terminals of the battery. The current sensor is operatively connected to the microprocessor to provide to the microprocessor an electronic signal indicative of the current between the terminals of the battery. Based on the signals received from the voltage and current sensors, the microprocessor calculates the total current discharge capacity of the battery and the present level of charge contained within the battery, and delivers electronic signals indicative of the total current discharge capacity and the present level of charge contained within the battery to the display means.
