IIT-G develops way to boost Litium-ion battery performance
Guwahati: Researcher of IIT-Guwahati have developed an advanced technique to boost the overall performance of rechargeable lithium-ion batteries used in electric vehicles, the premier engineering technology institute said on Wednesday.
The technique can precisely estimate the stage of charge (SOC), which reflects the remaining capacity of the battery. This helps in knowing how much more charge can be withdrawn before the battery gets fully discharged, a release issued by the premier engineering technology institute said.
The knowledge of the remaining capacity helps to optimize the battery capacity utilization, prevent overcharging and undercharging of the battery, increases its lifespan, reduces cost, and ensures the safety of the battery and its surroundings, the release said.
The research team comprises of research scholar Gautam Sethia, associate professor Sisir Kumar Nayak and professor Somanath Majhi from the department of electronics and electrical engineering, IIT Guwahati.
SOC cannot be directly measured by any sensor and can only be inferred by using the available measured qualities such as battery terminal voltage and current, it said.
As the highly non-linear characteristic of the lithium-ion battery makes it difficult to estimate the SOC accurately, a well-developed estimation algorithm is crucial in ensuring precise, reliable, and cost-effective SOC estimation.
