What is the open circuit voltage and working voltage of the battery?

What is the open circuit voltage of the battery? It means that when the battery is in a non-working state, that is, when there is no current flowing through the circuit under the condition that the battery is not connected to any external load, the voltage value between the two terminals of the battery is directly measured with an electric meter. The open circuit voltage cannot be used as a standard for weighing the battery voltage, but the measured open circuit voltage of a single battery can be compared with each other, and the state of charge change of the battery itself at different times can also be measured as a reference. Through the open circuit voltage of the battery, the state of charge of the battery can be judged. What is the operating voltage of the battery? Also known as terminal voltage, it refers to the potential difference between the positive and negative poles of the battery when the current is over in the circuit when the battery is working. In the battery discharge state, when the current flows through the battery, there is no need to overcome the resistance caused by the battery's internal resistance, so the working voltage is always lower than the open circuit battery, and the opposite is true when charging. Any electric facility can be the load of the battery, but the rated voltage of the load must be the same as that of the battery, and the power of the load should also be equivalent to the capacity of the battery.
