Method for monitoring operating parameters of a rechargeable power supply

A method for monitoring at least one parameter associated with a rechargeable power supply, said method comprising the steps of:

• generating a timing signal with a timekeeper;
• measuring, with a current monitor, the current flow out of the rechargeable power supply at select time intervals timed by the timing signal;
• measuring, with the current monitor, the current flow into the rechargeable power supply at select time intervals timed by the timing signal;
• and
• generating a timestamp in response to the completion of the charging of the rechargeable power supply,
• wherein said timestamp is indicative of a time when the battery ceases to be charged such that a self-discharge correction is capable of being calculated.

A method for monitoring parameters associated with a rechargeable battery, said method comprising the steps of:

• generating, with an oscillatory circuit, a timing signal;
• monitoring, with a temperature sensor, the temperature of the rechargeable battery at select time intervals time by the timing signal;
• measuring, with a voltage meter coupled to the rechargeable battery, at least an indication of the potential level of the rechargeable battery at select time intervals timed by the timing signal;
• measuring, with a current meter coupled to the rechargeable battery, at least indications of current flow into and out of the rechargeable battery at select time intervals timed by the timing signal;
• and
• accumulating, with an integrator coupled to the current meter, the net total of current flow into the rechargeable battery and the net total of current flow out of the rechargeable battery.
