Master's student Faculty of Information Technology Novosibirsk State University, profile "Internet of things", Dmitry Muravyov developed a system for monitoring and diagnostics of lithium-ion batteries. The solution includes a hardware module and a web service and is already available in the public domain for manufacturers and service companies.
The system allows testing batteries in various scenarios, recording their performance indicators and storing the results in a database for subsequent analysis.
— The main goal of the development is to increase the level of safety of devices using lithium-ion batteries as the main power source, — explains the author of the project Dmitry Muravyov. According to him, the development opens up opportunities for conducting not only standard measurements, but also regression and stress tests, which is especially important for checking the reliability of power sources.
Lithium-ion batteries are used everywhere today, from smartphones and laptops to electric vehicles and medical equipment. Their widespread use makes the issue of reliability and diagnostic accuracy especially relevant. Companies that develop or service devices with such batteries are interested in control tools that allow for a quick and objective assessment of the battery condition.
Dmitry Muravyov's development consists of two parts. The hardware part of the device is assembled from widely available components that can be purchased inexpensively on marketplaces. It allows you to set charging and discharging profiles, record operating parameters and transfer them via Wi-Fi to a web service or write them to an SD card. The built-in display shows the indicators in real time. The web service provides control of the device, allows you to set complex testing scenarios and analyze data.
“We made the system as accessible as possible – the code is written in Python, and anyone with basic programming skills can modify it to suit their own needs,” notes Dmitry Muravyov.
According to the project's scientific director, Deputy Dean of the Faculty of Information Technology at NSU Alexander Vlasov, the idea of creating an open system was born as a result of cooperation with the YADRO company, which is the largest domestic manufacturer of computing equipment.
— Batteries are an integral part of many computing devices, and monitoring their condition is necessary both at the production stage and in research tasks at the design stage. We saw that the market lacks accessible open source solutions, so the appearance of such a tool is an important step, — says Alexander Vlasov. The prototype of the solution was created at the YADRO Laboratory at NSU with active consultation of the company's employees.
There are already devices for testing batteries on the market, however, as Dmitry Muravyov explains, they have significant limitations: low measurement accuracy, closed software without the possibility of modification, lack of remote control and flexible testing scenarios.
“The lack of a solution free of these shortcomings became an incentive to create our own system,” the developer emphasizes.
Today, the project is at the MVP (minimum viable product) stage. The system is already operational and allows for various testing scenarios. The limitations are charging voltage up to 4.6 V and maximum current up to 1.6 A. But the main thing is that the solution is completely open: the circuits can be assembled from available components, and the software can be downloaded from GitHub. This makes the system accessible to both researchers and companies that need their own battery quality control tool.
— It is very important that such developments appear in the public domain. In Russia, the segment of battery testing tools is poorly developed, and the emergence of publicly available solutions develops the entire industry. This is useful both for the IT business and for the country as a whole. In the YADRO laboratory, we try to promote exactly such useful projects from the point of view of the general infrastructure. Directly, in a project like Dmitry's, it is difficult to trace the benefit, but we hope that our devices, which we use every day, will become a little safer and more reliable, — notes Alexander Vlasov.
Dmitry Muravyov himself emphasizes that he is ready to develop the project if interested partners appear. In the meantime, his system has already found practical application: a similar device was assembled and tried to be used by one of the Novosibirsk organizations working with equipment, where it is also necessary to test power elements.
