1. An apparatus, comprising:
- an electrical battery;
a sensor configured to provide an electrical signal correspondent to a temperature of the electrical battery; and
circuitry configured to quantify the electrical signal and to store digital data corresponding to the temperature and a timestamp, the circuitry also configured to communicate the stored digital data to another entity, and the circuitry further configured to determine a time-rate-of-change of the temperature of the battery.

Abstract
Methods and apparatus are provided related to thermal protection of electrical batteries. A sensor senses the temperature of a battery and a corresponding digital signal is digitally derived. Date, time and temperature data are written to storage media. A time-rate-of-change of the battery'"'"'s temperature is determined and used to establish operational periodicity. Stored digital data can be communicated to another entity, temperature or time-rate-of-change values used to trigger an alarm or system shut-down, and so on. Electronic circuitry toggles between an active mode and a power-conserving sleep mode in accordance with periodic operating schedule.
