In the development of electric motorcycle, battery is the core power source of electric motorcycles, and different battery type technology will directly affect the vehicle range, stability and safety. With the continuous development of lithium battery technology, it is gradually replacing lead-acid batteries by virtue of its high energy density, long service life, light weight, and other advantages; lithium batteries can be divided into ternary lithium batteries (NCM or NCA) and lithium iron phosphate batteries (LFP) according to different materials. Both have differences in performance, service life and applicability, and have their own advantages in different usage scenarios.
High safety: LiFePO4 batteries are chemically more stable, with low risk of thermal runaway, strong resistance to high temperature, and are less likely to spontaneously combust or explode during charging and discharging, making them particularly suitable for urban commuter electric motorbikes that require frequent stopping or charging.
Cycle life: LiFePO4 batteries have a long cycle life, usually more than 2,000 cycles, capable of reaching 8-10 years, and can provide a longer use cycle. This is an affordable option for users with high long-term usage needs, reducing the frequency of battery replacement.
The energy density of LiFePO4 battery is higher than that of lead-acid battery and lower than that of Li-ion ternary battery, which is about 100-160Wh/kg, which means that its range is lower than that of Li-ion ternary battery under the same capacity. Therefore, if there is a high demand for range, LiFePO4 battery may be less suitable.
In terms of price, the production cost of lithium iron phosphate batteries is usually lower than that of ternary lithium batteries, because lithium iron phosphate batteries use almost no heavy metals and rare metals, and will be cheaper in raw materials, so they are more widely used in cost-sensitive economy electric motorcycles.
High energy density: Li-ion ternary batteries have a higher energy density than lithium iron phosphate batteries, about 200-250Wh/kg, which is 3-5 times higher than ordinary lead-acid batteries, and can provide a longer range. This feature has a significant advantage in scenarios with high requirements for range, making it ideal for electric cars and EVs.
Small size and light weight: compared to lithium iron phosphate batteries, lithium ternary batteries are usually lighter, and therefore can improve electric motorcycles.
Due to the characteristics of its chemical structure, lithium ternary battery is highly sensitive to heat, and is prone to thermal runaway at high temperatures, with a certain risk of spontaneous combustion. Therefore, the battery management system (BMS) of electric motorcycles is particularly important in the application of lithium ternary batteries, to ensure the safety of use by monitoring the temperature and voltage of the battery.
The cycle life of lithium ternary batteries is generally around 1,000 cycles, usually around 3-5 years, which, although lower than lithium iron phosphate batteries, still meets the needs of most electric motorcycles.
When choosing the right battery for your electric motorcycle, you need to choose according to your actual use needs:
In short, ternary lithium batteries and lithium iron phosphate batteries have their own advantages and disadvantages, in the choice, depending on the user's actual needs and budget for comprehensive consideration. Saintyear lithium batteries are suitable for the pursuit of high range and lightweight users, while lithium iron phosphate batteries have obvious advantages in terms of safety and economy. In the future, with the advancement of battery technology, the battery solutions for electric motorcycles may become more diversified to adapt to different usage scenarios and needs.
The safety of lithium batteries used in electric motorcycles must be given enough attention. When using lithium batteries, we should avoid overcharging, over-discharging, high and low temperature charging, waterproofing and moisture-proofing, using the original charger, controlling the charging time, avoiding battery collisions and impacts, regular inspection and maintenance, and not modifying without permission. It is recommended that you must fully and carefully read the battery manual before using a lithium battery electric motorcycle and perform safe operations to improve the safety of lithium batteries.
Yes, for example, the 60V 45Ah LiFePO4 battery on this website can be used in electric motorcycles or tricycles. Usually, electric motorcycle lithium batteries can be used in electric tricycles, but several adaptation conditions must be considered as a prerequisite, such as battery capacity, BMS, heat dissipation design, space structure size design, etc., and it may even be necessary to connect multiple batteries in parallel to achieve the desired effect.
60V 110Ah/150Ah lithium ternary battery(NCM) is a high-capacity battery, using top brand CATL cells, with a system capacity of 6.6kWh/9.18kWh, which can be used in electric tricycles, electric motorbikes and low-speed intelligent vehicles.
