To recap: the short circuit current is a function of several variables but is mostly determined by the nominal voltage and internal series resistance. If the positive and negative terminals are connected by a wire then the battery is by definition shorted. What the voltage of the battery is does not really matter.
In the shelved state, the open-circuit voltage has a good mapping relationship to the battery state of charge. Therefore, the open-circuit voltage characteristics of lithium-ion batteries are used to obtain its one-to-one correspondence with the state of charge .
The open-circuit voltage is the terminal voltage of the lithium-ion battery after being shelved for a long time. In the shelved state, the open-circuit voltage has a good mapping relationship to the battery state of charge.
Open Circuit Voltage is the potential difference between positive and negative terminals when no current flows and the cell is at rest.
When a load is connected and the circuit is closed, the source voltage is divided across the load. But when the full-load of the device or circuit is disconnected and the circuit is opened, the open-circuit voltage is equal to the source voltage (assume ideal source).
An alternative option, which does not require specific hardware, is analyzing the open-circuit voltage (OCV) curve of batteries. To calculate the OCV, sensors measuring the voltage, current, and temperature of each battery cell are sufficient. These values are already tracked by the battery’s inbuilt battery management system (BMS).
