BATTERY PRESENCE DETECTING METHOD, APPARATUS AND CHARGING SYSTEM
Abstract:
Embodiments of the present invention provide a battery presence detecting apparatus, including: a detection triggering module, configured to detect a charging current on a battery terminal and trigger a logic control module when the charging current is less than a preset current threshold; the logic control module, configured to turn off a battery charging system and instruct a charging and discharging balancing module to perform a charging operation and then a discharging operation on the battery terminal; and a detection determining module, configured to detect a voltage on the battery terminal when the discharging operation is performed and determine whether the voltage on the battery terminal is less than a preset detection voltage, and if the voltage on the battery terminal is less than the preset detection voltage, determine that the battery is absent, and otherwise, determine that the battery is present.
