Smart batteries are batteries with complex functioning. These microchips help them in informing the user on the current state of charge, and state of health. Smart batteries are highly preferred in computer devices, medical equipment, military tools, and video and digital cameras. The state of charge and state of health is crucial for functionality, and smart batteries are natural matches for such devices.

From mobile phones, tablets, and hearing-assisted devices to electric cars and drones, all such devices function through the power generated by the battery. The various types of smart batteries used by consumers include; maintenance-free, wet cells (flooded), gel cell, and absorbed glass mat.

The microprocessor-controlled charger is known as a smart battery charger. It works only with smart batteries equipped with special microchips that are programmed to communicate with the same brand’s charge.
The system intelligence is employed in the battery pack, concerning the safety feature. The SBS battery enables digital supervision through chip that manages the battery charge and facilitates communication in a closed loop. The analog signals from the chemical battery communicate with the charger to stop the charge with the addition of temperature sensing. The fuel gauge technology known as System Management Bus incorporates IC chip systems in single-wire or two-wire systems.

The innovation in the EV smart charging management system drives the sales of smart battery chargers. The conventional chargers cannot be connected to the cloud. But smart battery charges can be monitored, managed, and restrict the use of the remote device to reduce energy consumption.

There is a surging requirement for smart electric vehicle chargers and charging systems to develop a sustainable energy system that does not rely on fossil fuels for energy generation. A smart battery charger enables precise charging and due to this, the smart batteries are not likely to get overcharged. These chargers facilitate communication between the battery, equipment, and user.

The major companies operating in the industry are; Storage Battery Systems LLC, Exide Technologies, HindlePower Inc., Delta-Q Corporation, Associated Equipment Corporation, and Panasonic Corporation.
The constant advancements in the telecom, and consumer electronics industries drive the smart battery charger industry. 

In addition, the rising penetration of IoT, led by massive data collection from distributed nodes fuels the innovation in energy technology. For example, the smart farm depends on the numerous nodes expanded over hundreds of acres for data collection on soil moisture, weather, evaporation, and so forth. Such nodes are usually battery-powered and depend upon energy-harvesting techniques, such as solar power to facilitate the existing battery capacity.

Therefore, the rising adoption of smart devices that run on smart batteries in various industries increases the demand for smart battery chargers.
