Extending Battery Life by 20%: Russian Scientists Unveil New Charging Technology
Researchers in Siberia have created a fast-charging method that reduces overheating in lithium-ion batteries, promising longer life and faster charge cycles.
Scientists at Siberian Federal University (SFU) have developed a new charging algorithm for lithium-ion batteries that prevents overheating. According to the team, this technology could extend battery life by 15–20% while cutting charging time by as much as 15%.
Today, the most advanced method is considered to be pulsed charging, where the current is delivered to the battery in intervals. The traditional two-stage charging process is also widely used. Both approaches, however, come with trade-offs: they either significantly shorten battery life or require much longer charging times.
The Russian method introduces a stepwise approach, reducing charging current once certain voltage and temperature thresholds are reached. Researchers say the technology is particularly well-suited for public electric transport, where safety and efficiency are critical.
Just a week earlier, SFU also unveiled a mathematical model that optimizes the use of electric buses. The model makes it possible to return up to 30% of the energy normally lost during braking back to the grid.
