Electric two-wheeled vehicle batteries possess fundamental characteristics such as energy storage, cyclic charge-discharge capabilities, and stable power delivery, making them a core component of the vehicle's powertrain system. By storing electrical energy, the battery continuously supplies power to the motor while the vehicle is in operation, thereby enabling its propulsion function. Currently, the batteries available on the market for electric two-wheelers primarily fall into two categories: lead-acid batteries and lithium-ion batteries; these different types exhibit distinct variations in terms of weight, lifespan, and overall performance.
In terms of performance characteristics, electric two-wheeled vehicle batteries possess a specific "cycle life"-that is, the number of times they can undergo a complete charge-discharge cycle. Lead-acid batteries are characterized by lower costs and mature technology, though they tend to be heavier; lithium-ion batteries, conversely, feature high energy density, lighter weight, and superior range performance, leading to their increasingly widespread adoption in high-end vehicle models. Furthermore, batteries exhibit a certain degree of self-discharge; even when the vehicle remains unused for extended periods, the stored charge will gradually deplete, necessitating periodic recharging and maintenance.
