Here are some overall batterymanagement system design considerations for a smart home. Since your IP camera and videodoorbell may work outdoors, you want to make surethat they operate reliably at hot and coldoutdoor environment. High-performancechargers and gauges are preferred since theyhave parameters guaranteed over temperature range.
When the temperatureis low, your battery will have higherinternal impedance.
To have2S battery for cold weather in order to releaseits full power.
A gauge is helpful when itcomes to a sudden.
Change of the temperature since ithas a more accurate Coulomb counting algorithm versusroughly measuring the.
Battery voltage for thestatus of charge.
The second designconsideration is the runtime is very important.
It’s convenient tohave wireless devices. But on the other hand,it’s also annoying if you need to rechargethem very often. So first, get ICs that consumesmall quiescent current. Then an accurate readingof status of charge is also helpful. Make sure that there is nowaste of battery capacity. Third design consideration,long. Battery life is differentthan the battery runtime. When you refer tothe battery life, you want to make sure.
Thatyour battery capacities do good after severalyears of operation. This is specifically importantto smart home devices, as when you deploy them, youwant them to work reliably as long as possible as comparedto other consumer electronics. The secret to get long batterylife is to not overcharge it. Accurate and lowbattery voltage will keep batteries strongafter extended number of charging cycles. Fourth design consideration isthe power source’s flexibility. This point is related tolong battery. If you have a solar panel, forexample, for your IP camera, you will be able tocollect extra power, and you may not need to chargeyour IP camera again forever.
