EV abnormal diagnosis solution 'EVcheck'

Electric vehicle battery data acquired through OBD2 is transmitted from SI (Smart Indicator) to Battery Y Cloud through the smartphone of the electric vehicle user. Battery data acquired from the cloud is analyzed in real time for battery aging, stress, and cell-specific abnormalities based on Battery’s proprietary diagnosis technology. Diagnosis results are informed through the SI's LED and voice, and detailed information can be checked on the user's smartphone.
