Abstract
A method for monitoring various parameters and conditions of a rechargeable battery to accurately determine the remaining charge level of the rechargeable battery, and includes using a temperature sensor to monitor the temperature of the rechargeable battery. The potential level of the rechargeable battery is monitored with a voltage meter coupled to the rechargeable battery. The current flow into and out of the rechargeable battery is monitored with current meter coupled to the rechargeable battery. A current accumulator coupled to the current meter is used to accumulate the net total of current flow, and an oscillatory circuit is used to generate a timing signal to time selected functions.
