First, the original charger charger is best not to change, the speed limit control of electric vehicles do not get rid of. Because different manufacturers of chargers have their own needs, it is best not to replace the charger at will without the advice of professionals. If the speed limit controller is removed, the speed can be improved, but the safety will be reduced, and the speed limit control will also reduce the service life of the battery.

Second, protect the charger. Under normal circumstances, new electric vehicles bought back will come with instructions on how to protect the charger. However, most users do not have the habit of reading the manual, often after the problem, they will think of looking for the manual, often do something too late, because some new cars to buy back to read the manual must. Today, in order to reduce costs, the charger is basically not designed in the production process, which leads to the charger can not be misplaced (such as: trunk, front basket, etc.). If it is necessary to carry it under special circumstances, it is necessary to do some anti-vibration measures for the charger. After most chargers are vibrated, the internal potentiometer will shift, making the parameters inaccurate, resulting in an abnormal charging state. It should also be noted that it is best to maintain the ventilation of the charger when charging, if the ventilation performance is not good, it will not only affect the life of the charger, but also cause damage to the battery. Xiaobian advice: Buy a charger with a fan.
< br >
Third, maintain the habit of charging every day Even if your car still has a lot of power, even if your car can be used for 3-5 days on a single charge, but Xiaobian still recommends that you charge every day. Charging every day will keep the battery in a low cycle, which will also extend battery life. Some users think that the battery is best to use up after charging, in fact, this cognition is wrong, because the battery is now basically lead-acid battery, and its memory benefit is not large. Long-term discharge has a great impact on the life of the battery.

Fourth, the battery should be fully charged Most chargers in the indicator light has just become full state, in fact, the battery charged at that time is not fully saturated. In this case, the battery should be charged for 30-60 minutes more, which is quite beneficial to inhibit battery vulcanization, thereby increasing the service life of the battery.
< br >
In fact, after the battery is discharged, it will start the vulcanization reaction, and there will be an obvious vulcanization reaction in 12 hours. Timely charging, can effectively remove the less serious vulcanization, if not timely charging, these vulcanization reaction produced by the crystals, will gradually form coarse crystals, ordinary charger for large particles of vulcanization reaction crystals is insoluble, so that the long-term battery capacity will decline, resulting in a shorter battery life. In addition to the above daily charging, electric vehicles should be charged as much as possible after use so that the battery power is saturated.

Sixth, regular deep discharge battery used for a long time to regularly carry out a deep discharge, which is conducive to enhancing the activity of the battery, can increase the capacity of the battery in a small range. The method of complete discharge is to make the car reach the first undervoltage on a flat road. The thing to note here is the first undervoltage. After full discharge, the battery is fully charged. This will increase battery capacity in a small way.

Seventh, develop some good habits to save electricity in the process of cycling as much as possible to glide. For example, when going downhill, use the power off to glide. Enter the taxi ahead of time at traffic lights and try to avoid braking. You'd rather make one extra turn than one less brake when you can. Good driving skills can also indirectly increase battery life.

Eighth, pay attention to the charging environment under normal circumstances, the room temperature is about 25 ° C. At present, most chargers do not have an automatic control system to adjust the ambient temperature, and the general manufacturers are designed according to room temperature when designing chargers. Tips For northern users of winter electric vehicles in the low temperature state into the warm state, the surface of the battery will frost in order to avoid frost caused by leakage, you should wait until the battery temperature is close to the indoor temperature and then charge.

5, regular cleaning: regular cleaning of the external surface, the frame should be cleaned regularly to prevent rust; Wheels, bearings and bearing surfaces are coated with organic antistatic lubricants to ensure slippability
2 Core components such as electric vehicle batteries will gradually lose with the growth of use time, and should be replaced regularly; At the same time, attention should be paid to keeping the vehicle clean, timely check whether the various parts of the vehicle are damaged or worn, and timely repair or replacement.
3 The correct use of electric vehicles, avoid overloading or overuse and other improper behaviors, choose regular after-sales manufacturers or professional maintenance personnel for maintenance, can extend the service life of electric vehicles and reduce the probability of failure.
The answer is as follows: 1. Regular charging: When charging electric vehicles, choose a regular charger, and charge according to the time and method specified in the instruction manual to avoid overcharging or insufficient charging.
2. Tire maintenance: the tires of electric vehicles should maintain proper air pressure to avoid blowout or insufficient grip. It is also necessary to check tire wear regularly and replace severely worn tires in time.
3. Waterproof and moisture-proof: electric vehicle circuit system is easy to be damp, so pay attention to waterproof and moisture-proof. Avoid driving on rainy days or when there is water on the road.
4. Regularly check the battery: the battery of the electric vehicle is an important part of it, and it is necessary to regularly check the battery power, whether the electrode is corroded, and whether the battery box is damaged.
5. Keep the body clean: often clean the body, seats and shell of the electric vehicle, which can maintain the beauty of the car and extend the service life of the car.
6. Maintenance: The maintenance of electric vehicles should choose a regular maintenance organization, and carry out maintenance in accordance with the time and method specified in the manual to avoid failure caused by unrepaired.
The normal use of electric vehicles also requires normal maintenance, including the front wheel and rear wheel bearing disassembly for oil maintenance, check whether the air pressure of the electric vehicle is normal, check whether the health of the battery is reduced due to long-term use of liquid shortage, so the normal maintenance of electric vehicles is also a part of the normal maintenance options can extend the service life of electric vehicles, I hope the answer can help you.
1. For the maintenance of electric vehicles, because some bearings on electric vehicles need to be regularly lubricated, the braking system and tires of electric vehicles also need to be replaced regularly. Electric car batteries also need to be replaced regularly. The battery of an electric car is a vulnerable component. Electric vehicle is a vehicle with simple structure, the main components of electric vehicle include frame, motor, battery and controller.
< br >
2, if it is a new purchase of electric vehicles, electric vehicle batteries should be fully charged before use.
As a high-tech travel tool, electric vehicles also need a certain amount of daily maintenance to ensure their long-term operation and life. Here are some suggestions for electric vehicle maintenance:
Electric vehicles need to be charged regularly, but do not overcharge to avoid shortening battery life. Usually can control between 30% and 80% of the electricity for charging.
After rainy days, it is necessary to wipe the water on the electric vehicle in time to avoid oxidation and corrosion. At the same time, to keep the electric car clean, and use the appropriate car cleaning agent.
Regularly check whether the battery, motor, tires, brakes, lights and other components of the electric vehicle are working properly, and replace the damaged parts in time.
When replacing electric vehicle tires, choose the correct specifications of tires, and ensure that the tire pressure is moderate.
For electric vehicles that are not used for a long time, the battery needs to be removed and stored in a dry and ventilated place to avoid excessive discharge or damage.
Pay attention to the riding mode of electric vehicles and avoid overloading or speeding to extend their service life.
When using an electric vehicle in a high temperature environment, pay attention to the heat dissipation of the battery and the motor to avoid excessive heat causing damage.
In short, electric vehicle maintenance should pay attention to details, and carry out regular inspection and maintenance according to the actual situation, in order to ensure that it plays a long-term and stable role.
Maintenance of electric vehicle battery:

1, rigorous choice of chargers There is a word widely circulated in the industry: the battery is not bad, it is bad. So the choice of charger is very important. The charger used with the car should match the battery pack and meet the requirements of the charger parameter table in this description, otherwise it will damage the battery performance.
< br >
2, accurately grasp the charging time in the process of using electric vehicles, should be based on the actual situation to accurately grasp the charging time, it is best to charge the battery after using about 80% of the power, if the battery is used up, the power should be turned off, do not use the battery 'rebound voltage' to force driving, in order to prevent 'overdischarge' and shorten the battery life. Battery continuous charging time more than 10 hours, the charger still does not change the lamp or the battery hot phenomenon, should immediately stop charging by the battery after-sales service, it is prohibited to continue charging in the case of the charger does not change the lamp.
< br >
3, regular inspection to avoid exposure to the battery can not be close to the fire source, heat source, hot season strictly prohibited direct exposure to the sun, the temperature is too high environment will make the battery internal pressure increase so that the battery pressure limiting valve is forced to open automatically, the direct consequence is to increase the battery water loss, and the battery excessive water loss will inevitably lead to a decline in battery activity, accelerate plate softening, charging the shell heat, Shell bulge, deformation and other fatal damage. At the same time, the battery should also avoid severe vibration, collision and short circuit of the positive and negative terminals.
< br >
4, it is strictly prohibited to suspend the battery charge in the state of loss, usually the user can directly load the car to use, such as shelving a long time (more than 2 months) before use should be added to charge, plug the charger into the battery box and then connect 220 volts alternating current, the charger continues to charge after the green light 1 to 2 hours, you can stop charging.
Electric vehicles are mainly to do wire, battery and motor maintenance.
Electric vehicle battery needs to be charged in time, battery power can basically maintain 2-3 days, if a long time storage, must be fully charged battery, battery is strictly prohibited in the state of loss, storage battery in the state of loss, it is easy to appear salinization, lead sulfate crystal attached to the plate, easy to cause insufficient charging, battery capacity is easy to decline, The longer the battery is idle in the state of loss of power, the more easily the battery is damaged.
< br >
If there is a problem with the battery, it should be repaired in time to ensure the life of the battery to the maximum extent, in order to avoid large current discharge of the battery, the electric vehicle must use the pedal when starting and carrying people uphill, to avoid the battery to release large current instantaneously.
Usually, the maintenance of electric vehicles is very important, such as often cleaning the dust and dirt on the battery cover, keeping the battery dry and clean, and preventing the battery from self-discharging.
< br >
1. A new electric car should be fully charged before use. 2. Keep the battery dry and clean. Make sure to remove dust and dirt from the battery cover. Keep the battery dry and clean to prevent the battery from discharging itself.
3. The battery on the electric bicycle should be firmly installed. When the battery is removed and charged, it should be firmly installed on the electric bicycle to prevent the battery from being damaged by vibration during riding. Do not throw, roll or press the battery during handling. 4. Start with an electric bike. When you start, you should use your pedal. If you don't have a pedal, you can push the ground with your feet to help you get started. When going uphill, use pedals to assist the electric bicycle to go uphill, so as not to discharge too much current and damage the battery.
5. Get into the habit of charging your battery every night. Do not let the battery in a state of low power for a long time, develop a good habit of charging the battery every night. When not used for a long time, it should be fully charged and placed in a cool and dry place for regular charging, generally for 10 days.
6. Don't overdischarge the battery. When riding regularly, be careful not to overdischarge. After the battery is discharged to the termination voltage, the continuous discharge is called overdischarge. Excessive discharge easily leads to a serious shortage of battery power, which greatly shortens its service life. Therefore, when using the battery, try to avoid deep discharge, light discharge, and frequent charging. In general, it is best to charge the battery once when the depth of discharge is 50%. Electric bicycles generally have undervoltage protection. When there is only one indicator on the battery, turn off the power and charge the battery with the pedal as soon as possible to avoid excessive discharge.
