1 TARIFF AN ENERGY RECOVERY SYSTEM Technical Area 5 This invention reduces the risk of thermal radiation during electric vehicle charging. It is related to an energy recovery system. Previous Tech 10 Electric vehicle batteries can be exposed to various risks during charging. In lithium-ion batteries in particular, excessive current during charging can lead to unstable cells. Conditions such as voltage fluctuations or excessive temperatures cause thermal propagation. This can lead to chain reactions called thermal emission. Thermal emission 15 This can cause the battery to pose a risk of fire or explosion, and damage the vehicle. This seriously threatens security. The systems currently in use... Thermal diffusion detection in battery management systems is based on temperature increase. This is being carried out. However, temperature-based detection is slow to respond. It does not allow for intervention in the early stages of the risk. Furthermore, 20 because these systems focus solely on controlling thermal radiation regarding the safe recovery of existing energy in the battery It does not include a solution.
