Factors Affecting Electric Vehicle Battery Life
The factors affecting electric vehicle battery life can be divided into three aspects. The first is the performance and quality of the battery itself, the second is the factors that cooperate with it in the electric vehicle, and the third is the usage of the user. We will focus on the second factor to discuss.
There are two main factors that affect the service life of the battery in the electric vehicle system:
One is the efficiency state of the motor, and the second is the design of the charger. If the efficiency range of the motor is narrow, on the one hand, the power consumption level will increase. On the other hand, if the motor often works in the low-efficiency area, the inside of the motor is easy to heat up. When the temperature is too high, the magnetic material will be irreversibly demagnetized. Over time, the efficiency will be further reduced. , thus entering a vicious cycle, the electric car will become a “electric tiger” in a sense, even if the battery is replaced, it will not help.
In addition, the factors that cause the motor to reduce the efficiency are: excessive wear of the brushes, wear of the plane commutator, wear of the deceleration system, etc. Therefore, customers should choose a motor with better performance And pay attention to keep in touch with maintenance services and replace worn parts when due, which will help you make good use of your electric vehicle. When electric bicycles enter thousands of households, electric bicycles will gradually be understood by people. Through a brief introduction to several main technical parameters of electric bicycles, I hope to help increase people’s understanding of electric bicycles.
How to prolong the battery life of electric bikes
For office workers who ride electric bikes, the most painful thing is that they are running out of battery. The most painful thing is that the battery is broken and it will cost a lot of money to replace it. In fact, how to use the battery is more economical, everyone knows, now I will tell you why the battery life is short.
Generally speaking, the greater the discharge current of the electric vehicle battery, the shorter the battery life; the deeper the discharge depth, the shorter the battery life. Electric vehicle batteries can cope with short-term high-current discharge, and the depth of discharge is not deep at this time. Small current discharge, even if the depth of discharge is slightly deeper, the battery life has little effect. Most afraid of continuous high current discharge and deep discharge.
When the speed of the electric vehicle is 35 kilometers per hour, the discharge current is generally 10A ~ 17A, that is, the discharge current is about 1C, so the discharge current is relatively large. Such batteries not only have a lower capacity, but also have a relatively short service life, and the depth of discharge of electric vehicles is relatively deeper. If the speed of the electric vehicle is maximized, and the braking and starting acceleration are frequent, the battery consumption will be greater. In this way, the actual service life of the battery of the electric vehicle is only as short as 3 to 6 months, that is to say, the optimal use power of the battery shows a downward trend after 6 months. You will also find that the electric vehicle is becoming more and more The slower it gets, the more boring it gets.
Again, I suggest that you do not accelerate or brake hard when riding an electric bike, which is the same principle as a car.
Electric vehicle maintenance precautions
1. Frequent charging
The lead-acid battery of electric vehicles should be recharged as needed , can not wait until the battery is used up to recharge, this will affect the battery life. If it is not used for a long time, charge it once a month. Please use the matching special charger for charging.
2. Multi-maintenance
In case of rain and accumulation of water, do not let the water flood the center of the wheel hub; turn off the switch in time when getting off the car, and keep the tires fully inflated; In the case of heavy loads such as headwind, use the pedal to assist; in case of failure, send it to the special maintenance department designated by the manufacturer for maintenance.
3. Frequent lubrication
Depending on the usage, the front axle, rear axle, central axle, flywheel, front fork, shock absorber pivot point and other components should be lubricated every six months to one year One scrubbing and lubricating (molybdenum disulfide grease is recommended). The transmission parts in the electric wheel hub have been coated with special lubricating oil, and users do not need to scrub and lubricate by themselves.
