To understand the basic principle of battery properly, first, we should have some basic concept of electrolytes and electrons affinity. Actually, when two dissimilar metals are immersed in an electrolyte, there will be a potential difference produced between these metals.
This electrical potential difference or emf can be utilized as a source of voltage in any electronics or electrical circuit. This is a general and basic principle of battery and this is how a battery works. All batteries cells are based only on this basic principle. Let’s discuss one by one.
Using power from the traction battery pack, this motor drives the vehicle’s wheels. Some vehicles use motor generators that perform both the drive and regeneration functions. Takes the incoming AC electricity supplied via the charge port and converts it to DC power for charging the traction battery.
Rechargeable batteries (like the kind in your cellphone or in your car) are designed so that electrical energy from an outside source (the charger that you plug into the wall or the dynamo in your car) can be applied to the chemical system, and reverse its operation, restoring the battery’s charge.
EV batteries are charged by plugging the vehicle into an electric power source. Although electricity production may contribute to air pollution, the U.S. Environmental Protection Agency categorizes all-electric vehicles as zero-emission vehicles because they produce no direct exhaust or emissions.

When the battery is charging, the lithium ions flow from the cathode to the anode, and the electrons move from the anode to the cathode. As long as lithium ions are making the trek from one electrode to another, there is a constant flow of electrons. This provides the energy to keep your device running.
