Efficient Battery Presence Detection Without Charging Interruptions
Here’s PatSnap Eureka !
Summary
Problems
Existing battery presence detection methods for rechargeable batteries with only a '+' and '-' terminal are inefficient, as they require periodic disconnection of the charging loop, leading to increased charging time and energy consumption, which reduces system efficiency and battery life.
Innovation solutions
A battery presence detecting apparatus and method that detects charging current thresholds, performs charging and discharging operations on the battery terminal, and determines battery presence based on voltage comparisons, avoiding periodic loop disconnection and minimizing energy loss.
TRIZ Analysis
Specific contradictions:
General conflict description:
Principle concept:
If periodic disconnection of charging loop is used for battery presence detection, then detection can be performed, but charging time increases and system efficiency decreases
Why choose this principle:
The patent implements continuous battery presence detection through the detection triggering module that continuously monitors battery status without interrupting the charging loop, allowing charging to proceed uninterrupted while detection occurs continuously in the background
Principle concept:
If periodic disconnection of charging loop is used for battery presence detection, then detection can be performed, but charging time increases and system efficiency decreases
Why choose this principle:
The detection triggering module performs preliminary detection of battery presence before full charging operations commence, and the logic control module prepares detection sequences in advance, allowing the system to detect battery presence proactively without waiting for charging interruptions

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.
