Abstract:
Objective To design a circuitry for the indication of the remaining capacity of battery.The circuitry can remind the user of charging in time for normal operation of instruments and prevention of early invalidation due to the over-discharge of battery.Methods The circuitry was designed totally based on hardware which used general electronic components.Results The circuitry functions was dependable and reliable with accurate indication in radar based non-contact life detecting devices.Conclusion The whole design is simple and needs no programming technology.The PCB is small,and the debugging is simple.Moreover,it can be applied to indication of various capacity and voltage.
