How to extend the lifespan of electric vehicle batteries
Factors affecting the lifespan of electric vehicle batteries
The factors that affect the lifespan of electric vehicle batteries can be divided into three aspects. Firstly, it is the performance and quality of the battery itself, secondly, the factors that cooperate with it in electric vehicles, and thirdly, the user's usage situation. We will focus on discussing the second factor.
There are two main factors that affect the service life of batteries in electric vehicle systems:
One is the efficiency status of the motor, followed by the design of the charger. If the efficiency range of the motor is narrow, on the one hand, the power consumption level increases, and on the other hand, it often works in low efficiency areas, making it easy for the motor to generate heat internally. When the temperature is too high, the magnetic material will undergo irreversible demagnetization, and over time, the efficiency will further decrease, leading to a vicious cycle. This electric vehicle will become a "power tiger" in a sense, even if the battery is replaced, it will be of no use.
In addition, factors that can reduce the efficiency of the motor include excessive wear of the brushes, wear of the flat commutator, wear of the deceleration system, and so on. Therefore, customers should choose a motor with better performance and pay attention to maintaining contact with maintenance services and replacing worn parts when they expire, which helps to make good use of the electric vehicle. When electric bicycles enter thousands of households, they will gradually be understood by people. By briefly introducing several main technical parameters of electric bicycles, it is hoped that it can help increase people's understanding of electric bicycles.
How to extend the lifespan of electric vehicle batteries
For office workers riding electric bikes, the most painful thing is that they run out of battery while riding. The most painful thing is that the battery is broken and they have to spend a lot of money to replace it. In fact, how to use batteries is more economical, and everyone is aware of it. Now let me tell you why batteries have a shorter lifespan.
Generally speaking, the larger the discharge current of electric vehicle batteries, the shorter their lifespan; The deeper the discharge depth, the shorter the battery life. Electric vehicle batteries can cope with short-term high current discharge, at which point the discharge depth is not deep. Low current discharge, even if the discharge depth is slightly deeper, has little impact on the battery's lifespan. I am most afraid of continuous high current discharge and deep discharge.
When the speed of an electric vehicle is 35 kilometers per hour, the discharge current is generally between 10A and 17A, which is around 1C, so the discharge current is relatively high. Such batteries not only require a decrease in capacity, but also have a relatively short lifespan. The discharge depth of electric vehicles is also relatively deeper. If the speed of an electric vehicle is maximized and braking and acceleration are frequent, it will consume more battery. This actually results in the actual service life of the electric vehicle battery being only a short 3-6 months, which means that the optimal power of the battery will decrease after 6 months. You will also find that the electric vehicle is becoming slower and less powerful.
Once again, the editor suggests that when riding an electric bike, do not accelerate or brake hard, as this is the same principle as a car.
Precautions for electric vehicle maintenance
1. Frequent charging
Electric vehicle lead-acid batteries should maintain the habit of charging as needed and should not wait until the battery runs out before charging, as this will affect the battery life. If not used for a long time, charge once a month. Please use the matching dedicated charger for charging.
2. Multiple maintenance
In case of rain and accumulated water, do not let the water flood the center of the wheel hub; Turn off the power switch in a timely manner when getting off the car, and ensure that the tires are fully inflated during normal times; Under heavy loads such as uphill and windward conditions, use foot pedals to assist; If there is a malfunction, promptly send it to the manufacturer's designated maintenance department for repair.
3. Frequent lubrication
According to usage, components such as the front axle, rear axle, center axle, flywheel, front fork, and shock absorber pivot should be cleaned and lubricated every six months to one year (molybdenum disulfide grease is recommended). The transmission components inside the electric wheel hub have been coated with special lubricating oil, so users do not need to wipe and lubricate them themselves.
