How often is it most cost-effective to replace it?
As one of the most affordable commuting tools for ordinary people, the service life of electric two-wheeled vehicles is also set. The price of a cheap one is more than 1,000 yuan, and the price of an expensive one is tens of thousands. Its normal design life is different. So, how many years can our ordinary household electric two-wheeled vehicles last? How often is it most cost-effective to replace it? Let me share with you today
The life of an electric vehicle is related to core components such as the frame, battery, and motor. Under ordinary urban household conditions:
Lead-acid battery electric vehicle: The cycle life of lead-acid batteries is generally around 300-500 times. If calculated based on 300 charge and discharge times per year, it can be used for about 1-1.5 years. However, in actual use, if properly maintained, such as not deep discharge, avoid high-temperature charging, etc., the overall use of lead-acid battery electric vehicles can be 8-10 years.
Lithium battery electric vehicle: The cycle life of lithium batteries is relatively high, generally around 500-1000 times. Calculated based on 300 charge and discharge times per year, lithium batteries can theoretically be used for 1.5-3 years. Under normal use, the service life of lithium battery electric vehicles is usually 5-8 years. If the use environment is good and maintenance is in place, some high-quality products can even be used for more than 10 years.
In the case of high-frequency use and seaside use:
Frequency and intensity of use: If the electric vehicle is used for a long time every day and has a high mileage, the wear of each component will accelerate and the life will be shortened accordingly. For example, in high-frequency use scenarios such as couriers and takeaways, electric vehicles may suffer more serious losses in 2-3 years.
Use environment: In harsh environments such as high temperature and humidity, the battery, motor, controller and other components of electric vehicles are prone to corrosion and aging, which will reduce the service life of electric vehicles. For example, in the southern coastal areas, high humidity and salt spray environments may cause the metal parts of electric vehicles to rust and the electronic components to be damaged, resulting in the overall life of the electric vehicle being shortened by 1-2 years.
Whether to replace an electric vehicle should be considered from three perspectives
Increased maintenance costs
Lead-acid battery electric vehicles: Generally, it is more cost-effective to replace them after about 3-4 years of use. Because after 3-4 years, the endurance of lead-acid batteries will drop significantly, and the charging efficiency will also decrease. Frequent battery replacement may be required, and the cost of battery replacement is high, which is about one-third to one-half of the cost of buying a new electric vehicle. At this time, if the frame, motor and other parts of the electric vehicle are also aging and failing, and the maintenance cost is increasing, then it is more economical to replace a new electric vehicle.
Lithium battery electric vehicles: You can consider replacing them after 5-6 years of use. After 5-6 years, the capacity of lithium batteries may drop to about 70%-80% of the initial capacity, and the battery life will be significantly shortened, affecting the user experience. In addition, the replacement cost of lithium battery packs is high, close to half of the price of a new electric vehicle or even higher. If other parts of the electric vehicle also have serious failures at this time, and the maintenance cost is high, you can consider replacing a new car.
Reduced safety of electric vehicles
When electric vehicles have safety hazards such as frame deformation, significant decline in motor performance, and failure of the brake system, or frequent failures after maintenance, affecting normal use and safety, they should be replaced in time even if the service life has not yet expired.

Poor experience
If consumers have higher demands for the comfort and intelligence of electric vehicles, and the existing electric vehicles cannot meet them, even if the vehicle can still be used normally, they can consider replacing it in advance according to their own economic situation. On the whole, ordinary electric vehicles can be ridden for up to 8-10 years, and high-quality electric vehicles can be ridden for more than 10 years. Of course, most car owners may need to replace new cars in advance. When the maintenance cost increases, the safety of electric vehicles decreases, and the user experience is poor, they need to replace new cars.
