Electrical Engineering/Alarms for Battery Power consumed in Electronic Gadgets.


Dear Prof Cleggsan

Is it possible to build electrical circuit with alarms for indicating Battery Power consumed in electronic gadgets viz cameras, toys, watches, calculators etc ?.

For example :

Similar to alarm which we manually set in clocks, the electrical circuit designed will calculate the battery power consumed and when it is say 10% battery power remaining (low on battery, drained), alarms will buzz to the consumer as warning signals before 2-3 days in advance for the respective electronic gadgets. This process will be automated.

Awaiting your reply,

Thanks & Regards,

Yes, it can be part of the charge monitoring software inside the product. Many cordless phones already have such features builtin as does laptop and tablet computers - at least to some degree or another.  It is merely a function of the designers deciding if it has merit to include such a feature and it the cost of implementing it is worthy of user interest.  

Two or three days in advance may be pushing the feature a little as the prediction of power usage in most devices is not a linear function; i.e., the power consumption varies depending on what the product is doing.

Hope this helps.
