Electric motorcycle

The application of batteries in electric motorcycles is a key factor driving the development of the electric motorcycle industry. The following analysis will be conducted from four aspects: technical characteristics, application status, comparison of advantages and disadvantages, and future trends:

1、 Technical features and performance advantages
High energy density: Lithium batteries have a much higher energy density than traditional lead-acid batteries, and can provide longer range under the same volume. For example, lithium iron phosphate batteries are widely used in mid to high end vehicle models, and their high energy density characteristics significantly improve the single charge travel distance of electric motorcycles.
Lightweight design: Lithium batteries weigh only a quarter of lead-acid batteries, which significantly reduces the overall weight of the vehicle and improves handling flexibility and acceleration performance.
Long cycle life: The cycle life of lithium batteries generally exceeds 1000 times. Calculated based on daily charging and discharging, the service life can reach more than 3 years. In contrast, lead-acid batteries have a cycle life of only one-fifth of their original lifespan and require more frequent replacement.
Fast charging capability: Supports fast charging technology, some models can charge 90% of their battery in 6 minutes, significantly reducing charging waiting time.
Low self discharge rate: The monthly self discharge rate is less than 5%, while the indicator for lead-acid batteries is as high as 10% -15%, resulting in less power loss when parked for a long time.

2、 Market Application Status
Mainstream technology route: Lithium batteries have become the mainstream power source for electric motorcycles, especially with a continuous increase in penetration rate in high-performance models. Renowned brands have achieved a breakthrough in range by equipping lithium batteries, with some models having a range of over 150 kilometers.
Differentiated technology solution: Some manufacturers adopt graphene batteries as an alternative solution, which improves performance by optimizing the structure of lead-acid batteries. For example, the 72V38Ah graphene battery operates stably in a wide temperature range of -30 ℃ to 60 ℃ and has a manufacturing cost 37% lower than lithium batteries, making it suitable for cost control sensitive markets.
Charging infrastructure support: With the increase in the number of electric motorcycles, the construction of urban charging networks is accelerating. Some cities have achieved dense coverage of charging stations in commercial and residential areas, with a daily service frequency of more than 20 times per station.
