The invention provides a storage battery charging method and device and vehicle-mounted equipment, and belongs to the field of new energy vehicles. The method comprises the steps that a BCM obtains a detected full-charge voltage value of a storage battery, wherein the full-charge voltage value of the storage battery is detected under the condition that the storage battery is fully charged; the BCM determines a voltage detection period according to the detected full-charge voltage value of the storage battery, wherein the voltage detection period is in positive correlation with the full-charge voltage value of the storage battery; the BCM outputs the determined voltage detection period to the remote information processor, so that the remote information processor awakens the BCM when the voltage detection period is reached; the BCM obtains the detected voltage value of the storage battery; and when the voltage value, detected by the voltage sensor, of the storage battery is lower than the charging threshold voltage, the BCM awakens the BMS to charge the storage battery. According to the invention, the voltage detection period of the voltage sensor is adjusted according to the full-charge voltage value of the storage battery, so that the phenomenon of power shortage of the storage battery within the charging interval is avoided.
