Choosing the Ideal Motorcycle Battery Voltage: Comparing 48V, 60V, and 72V

Electric motorcycles have surged in popularity due to their inherent advantages. In 2022 alone, sales reached a staggering 45 million, showcasing the widespread adoption of this mode of transportation. Among the prevalent battery voltages—48V, 60V, and 72V—selecting the right one significantly enhances the electric motorcycle experience. Here’s an in-depth comparison:

Why 48V, 60V, and 72V Batteries Lead the Pack

  1. Covering Endurance Needs:
  • For everyday commuting, the 48V battery offers mileage ranges from 35 km (48V 12Ah) to 100-120 km (48V 30Ah), catering to most user needs. However, the popularity of 60V and 72V batteries persists for specific reasons.
  1. Meeting Dynamic Demands:
  • In mountainous areas, the efficiency of 48V batteries may lag. Higher voltages like 60V and 72V ensure better performance on demanding terrains.
  • Higher voltages also elevate top speeds. While a 48V electric motorcycle might reach 35 km/h, 60V and 72V variants can hit 50-60 km/h, significantly enhancing commuting efficiency.
  1. Compatibility with Motor and Controller:
  • Most motors and controllers can withstand a maximum of 72V, ensuring durability and reduced strain on these components.
  1. Cost Considerations:
  • Balancing price with performance, the 48V, 60V, and 72V batteries cater to the common traveler’s daily needs without excessive costs.
  1. Battery Box Design and Weight:
  • Lead-acid batteries at higher voltages occupy more space and increase vehicle weight. In contrast, lithium-ion batteries offer higher densities with less bulk.

Speed and Cruising Ability

  • Speed varies significantly across battery voltages:
  • 48V: 25 km/h (basic requirement)
  • 60V: 40 km/h (common electric mopeds)
  • 72V: 50-80 km/h (some models reaching higher speeds)

Endurance Estimation

  • Calculations demonstrate the theoretical range for each voltage:
  • 48V: Ranges between 36 km and 60 km depending on battery capacity (12Ah to 20Ah).
  • 60V: Offers ranges from 65 km to 96 km with battery capacities of 20Ah to 32Ah.
  • 72V: Theoretical ranges vary from 115 km to 137 km based on capacities of 32Ah to 38Ah.

Practical Considerations

  • Suitability depends on individual needs:
  • 48V: Ideal for short commutes (36-60 km) without requiring a motorcycle license, fitting for city use and cost-efficient daily travel.
  • 60V: Suited for solo trips, serving those not needing a motorcycle license and looking for a balance between electric bicycles and motorcycles.
  • 72V: Perfect for longer trips, carrying adults, and applications requiring higher power and endurance, such as deliveries or combined travel.

Conclusion

The higher the voltage, the greater the potential for speed and endurance. Selecting the ideal voltage ultimately hinges on individual requirements and specific usage scenarios, allowing users to harness the most practical and efficient option for their needs.
