Voltage is the energy per unit charge. Thus a motorcycle battery and a car battery can both have the same voltage (more precisely, the same potential difference between battery terminals), yet one stores much more energy than the other. The car battery can move more charge than the motorcycle battery, although both are 12V batteries.
One end of the battery is attached to one of the metals, and the other end is attached to the other metal. A chemical reaction between the metals and the electrolyte frees more electrons in one metal than it does in the other.

Electrons flow from the negative end of the battery through the wire and the light bulb and back to the positive end of the battery. Electricity must have a complete path, or electrical circuit, before the electrons can move.
An electrochemical battery produces electricity with two different metals in a chemical substance called an electrolyte. One end of the battery is attached to one of the metals, and the other end is attached to the other metal. A chemical reaction between the metals and the electrolyte frees more electrons in one metal than it does in the other.
In [54, 95], the voltage differences and voltages of the cells in the battery string are used as the inputs of the FLC to adjust the battery balancing current. The inference engine of the FLC controller has produced the larger balancing current with a larger voltage difference and cell voltage.
A transformer changes the voltage of electricity in a conductor or power line. High-voltage transmission lines, such as those that hang between tall metal towers, carry electricity over long distances to where it is needed. Higher voltage electricity is more efficient and less expensive for long distance electricity transmission.
Among RBs, lithium-ion battery technology is the most prominent about high specific energy and specific power. The lithium-ion battery pack consists of battery cells with low terminal voltage connected in series to meet the voltage requirement of the EV system.
