Why were the issues on my car not detected?

Car Battery Health Monitor detects battery-related problems based on the voltage data of the vehicle battery and the changes in the voltage history data. However, as the battery types and technical standards of vehicles are not completely consistent, and the battery voltages of various types of vehicles are also different, currently, only problems related to voltage can be detected and predicted within a certain range. For some particularly sudden problems or problems without warning, it is currently impossible to detect and predict. We will continue to study related detection technologies and algorithms, hoping to detect and predict more problems to further improve accuracy and timeliness.
