Internal Short Circuit Detection Device for Early Detection via Constant Current Charging Signal Analysis
This technology is a device that detects internal short circuit faults early by analyzing voltage and current signals during the constant current charging process of lithium-ion batteries.
Existing internal short circuit detection methods have limitations, as they struggle to detect minute initial short circuits, posing a risk of fire or explosion.
By analyzing constant current charging signals to detect short circuits early, this technology can be applied to battery safety management to prevent accidents before they occur.
Key Features:
- An internal short circuit early detection device comprising a processor and memory storing at least one instruction executed by the processor
- Instructions for acquiring battery voltage and current signals measured during the constant current charging process of a lithium-ion battery
- Instructions for calculating the current state of charge of the lithium-ion battery based on the battery voltage and current signals
- A device configured to detect internal short circuit faults early through constant current charging signal analysis
