BATTERY SYSTEM - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240113347 titled 'BATTERY SYSTEM
Simplified Explanation
The abstract describes a battery system that prevents over-discharge using a sensor element. The system includes a battery pack, a monitoring unit, and a control unit that calculates the battery pack's capacity condition, estimates capacity condition based on current and temperature, and adjusts discharge cutoff voltage to prevent over-discharge.
- Battery system with sensor element to prevent over-discharge
- Battery pack with multiple cells connected in series
- Monitoring unit to monitor battery pack condition
- Control unit to calculate capacity condition and adjust discharge cutoff voltage
- Prevents over-discharge by adjusting cutoff voltage based on capacity conditions

The abstract does not mention how the control unit communicates the adjusted cutoff voltage to the device to ensure proper operation and prevent over-discharge.
Are there any potential limitations or drawbacks to adjusting the discharge cutoff voltage to prevent over-discharge?
The abstract does not address any potential limitations or drawbacks that may arise from adjusting the discharge cutoff voltage, such as impact on device performance or battery efficiency.
Original Abstract Submitted
a battery system that avoids an over discharge with a simple sensor element is provided. the battery system comprises: a battery pack including a plurality of battery cells connected in series, a monitoring unit that monitors a condition of the battery pack, and a control unit that controls a discharge of the battery pack. the control unit calculates capacity condition a of the battery pack at a first discharge cutoff voltage based on the total voltage and the total current, estimates capacity condition b of the battery pack at the first discharge cutoff voltage based on the total current and the temperature, determines an occurrence of an over discharge based on the capacity condition a and the capacity condition b, changes the first discharge cutoff voltage to a second discharge cutoff voltage that is higher than the first discharge cutoff voltage, when the occurrence of the over discharge is determined.
