It is no wonder, then, that having the right batteries for IoT devices is significant. Battery-powered IoT devices are only as reliable as their power supply. Therefore, the ability to ensure the power economy and the battery life of a device is more crucial than ever.
Battery life is critical for IoT systems and is also one of the biggest hurdles while designing batteries. IoT systems work on one key principle- to sense the information and transmit it.
IoT systems work on one key principle- to sense the information and transmit it. If an IoT system’s sensor runs out of battery, information cannot be detected or transmitted further, and the entire system is practically rendered useless until replaced with another battery.
Battery Chemistry Most IoT devices use batteries whose chemistry is almost always primary (for one-time use) or secondary (rechargeable) Lithium-based. Other traditional battery chemistries are Lead Acid, NiCd, and NiMh.
Like any other battery, the battery life of an IoT device is determined using a simple formula – the battery capacity divided by the average rate of discharge. Minimizing the rate of discharge of the battery or maximizing its capacity will maximize its overall life.
While using TFT LCD displays for many IoT applications is unfeasible, the particular kind of data that most IoT devices handle — state information — suits them for bistable display technology. Bistable display technologies, and e-paper in particular, retain image information without consuming power. Power is used only when updating an image.
