The nominal voltage is the average voltage of the battery over its discharge cycle, while the maximum voltage is the highest voltage that the battery can reach when fully charged. For example, the 18650 batteries used by Tesla have a nominal voltage of 3.8 volts and a range of 3.3 to 4.2 volts, and a 17 amp maximum discharge …
Potential Difference (Voltage) • Electricity
Potential difference (also known as voltage) is defined as follows: Potential difference is the difference in potential energy for each electron.; Potential difference has the symbol V, and the unit of Volts: ; Higher-voltage batteries pump electrons to a higher electrical energy than lower-voltage batteries (e.g. 12V car battery vs 1.5V AA battery). ). Therefore, …
