The length of the service life of an electric vehicle mainly depends on the service life of the core components, the main frame, three electric systems (motor, battery, electronic control), and tires are basically fine, so an electric car will basically not have much of a problem!So the question is, how long is the service life of the frame, battery, motor, controller, and tires in an electric vehicle?I'll tell you the answer today!
Let's talk about the frame first, the frame is the base of the battery, if the frame is broken or damaged, then, the electric car basically has no point in repairing. Therefore, the frame is the core component of an electric vehicle. The frame generally has a single-tube and double-tube frame, according to the material, there are carbon steel, aluminum alloy, titanium magnesium alloy, in addition, the length of the life of the frame is related to the size of the pipe diameter, the thickness of the pipe wall, and the welding and painting processOne of the most durable is the titanium-magnesium alloy frame, which has a service life of more than 20 years and will not break!Aluminum alloy in 20 years, the current mainstream carbon steel frame in 10-15 years of service life!For an electric car, under normal riding, the frame can be used for more than 10 years to be qualified!
Speaking of batteries, they are mainly divided into two categories: lead-acid batteries and lithium batteries. Among them, in the case of normal use of household electric vehicles, the normal life of lead-acid batteries within 20Ah is 1Within 5 years. 20-3 years above 2ah. The life of lithium batteries within 20Ah is about 3 years, and the life of lithium batteries above 20Ah is 3-6 years. Some ultra-large capacity vehicle-grade lithium battery units can be used for more than 20 years!
Then talking about the motor, the motor is one of the most durable parts of the electric vehicle, and the service life of the ordinary hub motor is 6-10 years!If it is a liquid-cooled in-wheel motor that dissipates heat and cools down, the service life can reach more than 10 years!If the mid-mounted motor is regularly maintained, the service life can reach 15-20 years!
About the controller, belongs to the "brain center" of electric vehicles, it mainly has a lot of interfaces and wiring harnesses, the biggest problem of the controller is that it is easy to overheat, now it is generally used to use air cooling to cool down, after thermal expansion and contraction, the wiring of the controller is prone to poor contact, and there is no electricity to go. The normal service life of the controller is 5-8 years!Some have good heat dissipation and can achieve a life of more than 10 years!
Finally, tires are the most diligent parts of electric vehicles, and tires are also divided into vacuum tires, inner and outer tubes, and wire tires. Among them, vacuum tires are the most commonly used in electric vehicles. Under normal wear and tear, the front wheel tires are replaced for 6,000 kilometers. After 4000 kilometers of tires for one, vacuum tires **60-120 yuan only, depending on the specific model!
The above is the normal service life of the frame, battery, motor, controller, and tires of an electric vehicle!Many people's old bikes may not be broken after 10 years of riding, and the core reason is that there is nothing wrong with these core components. Tires, like batteries, need to be replaced regularly to avoid breakdowns, guys, what do you think about this?Welcome your message!
