The invention discloses a rapid battery charging management method and device and a storage medium, and relates to the field of charging management, and the method comprises the steps: collecting the initial
voltage, environment temperature and
transient response parameters of a battery before charging, and building an initial state
reference model of the battery; a micro-amplitude pulse disturbance current is superposed in a
constant current charging stage, dynamic equivalent
internal resistance is calculated in real time, and a battery behavior
feature vector is constructed in combination with a temperature change rate, a
voltage change trend and
voltage rebound time. And inputting the
feature vector into a safety evaluation model, generating a charging
safety coefficient, dynamically adjusting the charging rate or the charging power according to the charging
safety coefficient, and automatically triggering
current limiting, power reduction or power-off protection when abnormal deviation of the
internal resistance occurs or the temperature
rise rate exceeds a threshold value. According to the method, fine sensing and predictive
safety control of the internal state of the battery are achieved, charging efficiency and safety are both considered, and the method is suitable for portable
energy storage equipment such as a power
bank and a
hand warmer.
