The Internet of Things (IoT) is one of the hottest technological applications at present. But many Internet of Things smart devices often face the problem that power consumption is too fast, resulting in the shutdown of the smart device, and you have to go replace the batteries. This article will introduce you to two solutions that can provide adequate power for smart devices for the Internet of Things, and provide you with more options.
Non-traditional Battery Design Offers More Diverse Power Supply Combinations
Most of the Internet of Things (IoT) smart devices themselves cannot connect to household power and have to rely on batteries to provide electricity for sustained operation. Currently, most of the mainstream solutions use standard models of button cells or dry cells. However, due to the lack of battery capacity, the operation time of smart devices is often insufficient. In addition, the volume of many Internet of Things smart devices is not large (such as various sensors) and are not suitable for having multiple batteries built-in, therefore, how to provide more adequate power supply for IoT smart devices is the key for whether long-term operation of the Internet of Things can be realized.
In order to improve the operation time of IoT smart devices, we can consider from the two directions of open source and throttling. Open source is to increase battery capacity, throttling is to reduce energy consumption in the operation of the device. Because different smart devices have different ways to reduce energy consumption, this article will focus on the topic of open source (increasing battery capacity).
First, we will introduce the 196 HVC ENYCAP ENYCAP™ hybrid energy storage capacitor released by the Vishay company, which is a polarization energy storage capacitor with high capacity and high energy density, and possess excellent voltage flexibility. With a single battery it can support 1.4V, with multi batteries it can support 2.8V/4.2V/5.6V/7.0V/8.4V and other combinations. It can provide Stacked Through-Hole (STH, radial), Surface-Mount Flat (SMF), Lay Flat Configurations (LFC) with wires and connectors and other installation combinations, the service life can reach 2000 hours at 85℃, there is no need for battery balancing, it has soft and low transient voltage controlled charging characteristics, use of non-hazardous electrolytes allows it to be maintenance-free and service-free, and it offers a variety of advantages that conventional batteries cannot offer.
Vishay Company's 196 HVC ENYCAP™ hybrid energy storage capacitor has been widely applied in many fields, in addition to being applied to the Internet of Things smart devices, it can also be used as backup power for memory controllers, flash backups, real time clock power supply, flash lamps and wireless transmitters products. Capacitors are marked with their rated capacitance (F) and rated voltage (V), date code, negative/positive terminal identification and other information, convenient for knowing the specification of the product, at present, only ESD trays packaging is available.
In addition, we would like to introduce the Hybrid Pulse Capacitor (HPC) developed by Shenzhen Longsing Technology Co., Ltd., which is a new hybrid pulse capacitor that combines lithium ion battery technology with ultra-capacitor technology. This hybrid pulse capacitor is a long-life energy storage device designed for long-term use in harsh environments, has high power density and a long cycle life, and a relatively high charging voltage (up to 4.1V). Compared with conventional super-capacitors, it has a higher power density, enabling it to have pulse discharge at high current levels. Its operating temperature ranges from -40℃ to 85℃.
To complement the Internet of Things (IoT) applications, Longsing Company has pushed out an IoT battery pack that combines a composite pulse capacitor with a lithium thionyl chloride battery. Customers can match lithium thionyl chloride batteries of different capacities and sizes with composite pulse capacitors according to the expected service life and appearance of the product. High-capacity lithium thionyl chloride batteries can charge HPC, while HPC can output a large current and have a storage life of more than 10 years, a battery pack consisting of multiple lithium thionyl chloride batteries can provide higher capacity, and the annual self-discharge rate of the battery pack is less than 5%. HPC is responsible for providing high current pulses, a single HPC 1550 battery can provide up to a 5A pulse current at an operating voltage of 3.0V to 3.6V.
The HPC battery released by Longsing Company has many models, battery capacities from 30mAh to 230mAh, and lithium thionyl chloride batteries also have a wide range of capacities, and can be combined with different types of HPC batteries to provide a variety of capacity combination ranging from 1200 mAh to 19000 mAh. The maximum pulse current can be from 0.75A to 5A, providing great application flexibility.
The two types of non-traditional batteries described in this article can provide greater battery capacity for Internet of Things smart devices, and it also provides a variety of power output combinations. They can meet the different needs of all kinds of Internet of Things applications, and they are worth further exploration by the relevant product development companies.
