Launch of New Evaluation Board for SLB Series of Small Lithium-Titanate Rechargeable Batteries

NICHICON CORPORATION launched the 2nd generation evaluation board SLBEVAPAS01 to accelerate the design process for applications where the SLB series of small lithium-titanate rechargeable batteries are to be used. The SLB series has become a top-selling product in the small rechargeable battery market, having shipped over 90 million units in total since its launch in 2019. 

In order to promote carbon neutrality, disposable non-rechargeable batteries are being replaced by rechargeable batteries paired with environmentally friendly power generation from sustainable sources. The evaluation board allows for easy evaluation of power circuits incorporating the SLB series and various energy harvesting devices. The board is available in online distributors such as Digi-Key, Mouser, Sager Electronics and so on. 

Overview and Development Background

Long-life power supplies are essential for the development of IoT devices that require maintenance-free operation. Replacing the conventional non-rechargeable batteries with a power supply that combines an environmentally friendly power generation device and a rechargeable battery requires significant design work. Using this evaluation board makes it possible to easily examine the use of power supplies using environmentally friendly power generation.

Features

The SLBEVAPAS01 is an evaluation board that allows users to test the SLB series with various types of energy harvesting devices. With a built-in power management IC from e-peas, the harvested energy can be optimized via jumper configurations. The board is equipped with AC harvesting capabilities. The board features a 400 mA maximum current USB-C input for quick evaluation of SLB charging.
