The state of charge influences a battery’s ability to provide energy or ancillary services to the grid at any given time. Round-trip eficiency, measured as a percentage, is a ratio of the energy charged to the battery to the energy discharged from the battery.
To understand how EV charging works, think of electricity flowing into your car like in a plumbing system. The voltage, measured in volts, is like water pressure, and pushes an electrical current to the vehicle’s battery. The electrical current flow, measured in amps, is like the water’s volume.
Discharge Process: During the discharge process, the battery’s chemical reactions undergo a reversal. Lithium ions migrate from the negative electrode to the positive electrode, while electrons travel from the negative electrode to the positive electrode.
