The invention discloses a battery safety state detection method, device and equipment and a storage medium, and the method comprises the steps: transmitting high-frequency battery information to a vehicle-mounted communication terminal through a vehicle battery system when a vehicle runs, and enabling the frequency of the high-frequency battery information to be higher than 2 Hz; the high-frequency battery information is stored through the vehicle-mounted communication terminal; the vehicle-mounted communication terminal sends the high-frequency battery information to a cloud platform in response to a wake-up request of the cloud platform to the vehicle-mounted communication terminal when the vehicle stands; and detecting the safety state of the battery based on the high-frequency battery information through the cloud platform. According to the method, the high-frequency battery information is collected and utilized, the safety state of the battery can be well detected, meanwhile, based on the high-frequency battery information, the real-time state of the battery can be more accurately calculated, the mechanism state change of the battery can be more deeply found, and accurate early warning of battery faults can be more efficiently achieved.
