Electric Vehicle High-Voltage Safety Systems
At the ideal temperature of 77 F, a fully charged battery is at 3.6 volts in each cell. However, as temperatures deviate from this ideal, especially when it is an extreme deviation, individual cells do not all react the same and there will be variations in cell voltage. It is important that each battery cell voltage is balanced with one another.

electric circuits
The switch is open. This means, the charges could not flow through the circuit and complete the circuit. This is due to the gap in between the switch. So the applied energy is not converted to current even though the resistance is still there. Hence voltage will be there, where you applied it. Now, in the second case, there is no resistance.
