What is the difference in range between 72v20Ah and 60v20Ah?
2 Answers
60Ah batteries have stronger range capability than 20Ah ones, providing longer endurance. Theoretically, an electric vehicle equipped with a 60Ah battery can travel 288 kilometers, while one with a 30Ah battery can travel 144 kilometers. Battery Introduction: A battery is a type of accumulator, also known as a storage battery, which works by converting chemical energy into electrical energy. The batteries commonly referred to are lead-acid batteries, which mainly use lead and its oxides as electrodes and sulfuric acid solution as the electrolyte. Battery Working Principle: The negative electrode is made of lead plates filled with sponge-like lead, and the positive electrode is made of lead plates filled with lead dioxide, using 22-28% dilute sulfuric acid as the electrolyte. During charging, electrical energy is converted into chemical energy, and during discharging, chemical energy is converted back into electrical energy.
I'm quite fascinated by electric vehicles and have studied the principles of battery range. A 72V 20Ah and a 60V 20Ah battery have the same capacity but different voltages, resulting in a 240Wh difference in total energy. Simply put, the 72V stores more electricity. Assuming the same model and speed, it can cover about 20% more distance. I've tried recording data—when riding in the city, the 72V version typically runs about 30 kilometers farther due to higher energy density and possibly slightly better motor efficiency. However, it consumes power faster when climbing hills or carrying heavy loads. Replacing the battery is costly, but in the long run, it saves charging time and is more cost-effective. If you're after value for money, 60V is sufficient, but for long-distance trips, 72V is the better choice.
