A lithium-ion battery testing stand is being upgraded at Novosibirsk State Technical University (NSTU). The development, which is carried out within the framework of the Priority 2030 program, will make it possible to assess the resource of power plants and extend their life cycle in new conditions.
The engineers of NSTU-NETI, commissioned by Gazprom-Neft from St. Petersburg, launched a project to improve the lithium-ion battery testing stand. The equipment will make it possible to check spent batteries of urban electric vehicles and extend their service life in gentle conditions, for example, as storage devices in the energy sector to equalize peak loads, where operating modes are much easier.
An innovative stand developed at NSTU-NETI together with Chinese partners with the support of the Russian Foundation for Basic Research will help determine the energy intensity of lithium-ion batteries. According to the head of the Department of Electrotechnical Complexes of NSTU-NETI, Doctor of Technical Sciences, Professor Nikolai Shchurov, the upgraded device will make it possible to identify and reject individual battery cells that have degraded during vehicle operation, especially with frequent changes in driving and stopping modes.
"The development will help to discard degraded lithium-ion battery cells, test workable cells to reformat the assembly and create a new battery," said Professor Nikolai Shchurov, adding that the stand allows you to simultaneously test thirty cells and monitor the processes that lead to accelerated aging of battery cells.
The upgraded battery testing stand at NSTU-NETI will help not only give lithium-ion batteries a second life, but also partially solve the problem associated with the disposal of lithium-ion batteries. It should be recalled that NSTU-NETI, together with the Radio and Microelectronics Scientific and Production Association, is developing an automatic control system, information collection and data processing of traction substations for urban electric transport within the framework of the Priority 2030 program.
