The core reasons for the decline in Ebike battery life and the large gap between actual and nominal values are concentrated on the battery itself, usage habits and environmental factors. Reasonable adjustments can effectively improve battery life performance. First of all, the condition of the battery itself is key. The capacity of lithium batteries will naturally decay after long-term use. Generally, the decay will be obvious after 2-3 years of use. If the battery is stored improperly (such as long-term storage with full power or loss of power, storage in high/low temperature environments), the decay will be accelerated. Secondly, usage habits have a significant impact. Frequent rapid acceleration and braking will consume a lot of power. Long-term use of high-speed driving and heavy loads (such as carrying people and objects) will also significantly shorten the battery life. In addition, insufficient tire pressure will increase driving resistance and indirectly reduce battery life. Environmental factors cannot be ignored. Low temperature will significantly reduce the activity of lithium batteries. Battery life in winter may be only 60%-70% of normal temperature. Driving against the wind and climbing hills will also increase power consumption. Improvement methods: Develop good charging habits, avoid long-term storage of full power, charge in time when 20%-30% of the battery is left, and keep about 50% of the battery during storage; avoid sudden acceleration and braking when driving, switch to appropriate gears according to road conditions, reduce the load, and regularly check and replenish the tire pressure; try to store the battery indoors in winter, preheat before driving, and reduce the vehicle speed when going against the wind or climbing hills to reduce power consumption and extend the actual battery life.
