Battery Safety and thermal runaway in electric vehicles
Principal Investigator
Prof. Aravind Kumar Chandiran
Objective
- To study the catastrophic behaviour of batteries by understanding the battery response towards the actual Indian road and climate conditions.
Description
- Lithium-ion batteries are the widely accepted and successful energy source for E-mobility due to its excellent power density and energy density. However, few vehicles undergo thermal runaway resulting in vehicle fire and leaving casualties, In general, reasons of thermal runaway include over charging, internal short circuit, extreme external temperature, and adverse operating conditions. All these explosions are catastrophic and there is no prior alert or warning to the passenger/hardware, In our lab, thermal runaway of batteries was extensively studied for over 100 cells of different chemistries and manufacturers, in which the explosion pattern is highly impacted based on cell aging, abuse type, cell design, and chemistry, For the existing batteries in market, it is suggestible to adopt appropriate coolants with accurate thermal management systems to avoid heat accumulation within the batteries.
Impact
- In this proposal we propose to: Build a safety chamber, Study NMC/LFP battery chemistries for Indian temperature conditions, Prepare a complete paper on the battery safety conditions when operated in Indian road conditions, Train M.Tech and PhD students.
