We are also called "electric vehicles" for battery cars. It is a pure electric motor vehicle provided by the battery (battery), which is driven by electric motors (DC, AC, Strings, and Reliers).In recent years, it has been widely popularized in my country.Domestic battery cars are mainly used for tourists, patrols, and cargo. The main purpose of electric tourist vehicles is in parks, scenic spots, leisure resorts, universities, hospitals, golf courses, real estate companies and other places.The main use of patrol vehicles is to carry out public security patrols in the station square and dense places. The main purpose of electric carrier vehicles is at factories, port docks, and logistics warehouses.The main use of electric sanitation vehicles is to clean up the venue, clean the road, and transfer garbage.The service life of the battery car is generally 8 to 12 years, and the service life of the battery is generally 1-4 years (depending on the maintenance of the use)
How to buy battery cars
Look at the brand
There are many electric bicycle brands.Consumers should choose brands with long operating time, low repairs, good quality, and reputation.For example, buy companies that have been certified by the quality management system ISO9001-2000.
Heavy service
Because the components of each electric vehicle have not yet been universal and the maintenance cannot reach socialization, the electric bicycles you buy must pay attention to whether there are special maintenance service departments in the region. If the map is cheap and neglects after -sales service, it is easy to be fooled.
Choice
Electric bicycles can generally be divided into four types: luxury, ordinary, front and rear shock -absorbing types, and lightweight types.Luxury is complete, but the price is high, the ordinary structure is concise, and the economy is economical; lightweight, light and flexible, but the itinerary is short.Consumers should pay attention to this when buying.
Check accessory
The strength requirements and performance requirements of electric bicycle parts should be higher than bicycles.When buying, users should depend on the quality of the vehicle to choose parts, such as: whether the welding and surface of the frame and the front fork are defective, whether the manufacturing of all parts and components is excellent, whether the dual support is strong, whether the tires are selected for famous brands, fasteners, fasteners, fastenersWhether to prevent rust and so on.
Renewal mileage
A set of new batteries with a capacity of 36V/12AH is generally about 50 kilometers. Generally, the longest distance of ride daily is about 35 kilometers per day (because the road conditions affect the actual renewal mileage), riding every day ride every day.Those who have the longest distance of more than 50 kilometers must consider whether there is the possibility of charging twice a day.Without this possibility, it is not suitable to buy electric bicycles.
1. Check whether the appearance of the appearance, the surface of the paint, and the plating part is intact.
2. Actually operate in the manual and check the working status of the vehicle.The transition of the speed adjustment should be smooth, there is no impact on the start, the wheel rotates the spirit
Live, no stagnation, the sound of the wheels rotates soft, no abnormal noise, the brakes should be tight and moderate, and the braking is reliable.
3. Also check whether the auxiliary function (such as power display, speed, mileage display, etc.) should be in a normal state.
4. Whether the matching accessories, chargers, qualification certificates, manuals, and warranty cards are complete.
How to maintain battery car
1. Before using it with sufficient charging.The newly purchased electric vehicles should be used for adequate charging before use.Because many electric vehicles have been put on the store for several months or even more than half a year, they must be used in full and then used. It is best not to use it immediately after sufficient charging.
2. The battery should be installed firmly on the electric bicycle.The battery is charged. When installation, the battery must be installed firmly on the electric bicycle to prevent the battery from vibrating damage during cycling.In the transportation of the battery, it is forbidden to throw, roll, and press heavy pressure.
3. Keep the battery dry and clean.Frequently remove the dust and dirt on the battery cap, pay attention to keep the battery dry and clear to prevent the battery from discharging itself.
4. Develop a good habit of charging the battery every night.It must not allow the battery to be in a state of insufficient power for a long time, and develop a good habit of charging the battery every night.It is not used for a long time, it should be fully charged, placed a cool and dry place, and charged regularly, usually 10 days.
5. Just take the pedal.When the electric bicycle just starts, you must use the pedal. If you do n’t have a pedal, you can push the ground to help start. When you go uphill? Use the foot to help the electric vehicle go uphill to avoid the battery that is too large and damage the battery.
6. Do not allow the battery to discharge, so as to be a shallow diligence.When riding, be careful not to let the battery discharge. After the battery is discharged to the termination voltage, it continues to discharge and is called over -discharge.Excessive discharge can easily cause the battery to be seriously lost, thereby greatly shortening its service life.Therefore, when the battery is used, we should try to avoid deep discharge, so as to achieve shallow diligence. Generally, it is best to charge the battery when the battery depth is 50%.Electric bicycles generally have an underwriting protection function. When there is only one display lamp on the battery volume display, the power should be turned off, the foot should be used, and the battery should be charged as fast as possible to avoid the battery discharge.
7. The battery must not be unlocked for a long time, and it should be turned off immediately when not in use.When the termination voltage is terminated, the internal resistance is large, and the concentration of the electrolyte is very thin, especially in the polar pores and the surface is almost neutral. When the internal resistance has a tendency to fever, the volume expansion, the discharge current is large, the obvious heat appears or even appears even appears or even appears.Heating deformation, at this time the lead sulfate concentration is particularly large, and the possibility of short circuit of survival crystal branches increases. Moreover, lead sulfate will be crystallized into larger particles at this time, that is, the formation of irreversible sulfatePoor and even cannot be repaired.The battery should be used to prevent discharge, and "under pressure protection" is an effective measure.In addition, because the "lack of voltage protection" of the electric vehicle is controlled by the controller, other equipment other than the controller such as voltage meters, indicator lights and other power consumption appliances are directly powered by batteries.Instrument control, electric vehicle lock switch starts to use electricity once it is closed.Although the current is small, discharge will occur if the discharge is 1-2 weeks for a long time.Therefore, it is not necessary to unlock for a long time, and it should be turned off immediately when not in use.
8. Avoid charging.When the charger display is full, it stops charging, and it cannot be charged overnight or even a few days.Excessive charging will cause the polar plate activated material to harden and fall off, and produce water loss and battery deformation.The battery runs in the high temperature season, and there are mainly over -charging problems.Therefore, in the summer, we should try to reduce the battery temperature to ensure good heat dissipation, prevent charging after sun exposure, and stay away from the heat source.Avoid charging, in addition, you must choose the charger parameter to match the battery well, and fully understand the operating status of the battery in the high temperature season, and the changes in the entire service life.Do not put the battery in an overheated environment during use, especially when charging, you should stay away from the heat source.After the battery is heated, it is necessary to take cooling measures. When the temperature of the battery is returned to normal, it must be charged.The installation location of the battery should be as good as possible to ensure good heat dissipation. When the heat is overheated, the charging should be stopped, and the charger and the battery should be checked.When the battery discharge depth is shallow or the ambient temperature is high, the charging time should be shortened.
9. Avoid long -term electricity.Long -term power loss will cause polar plate sulfide.In the case of low temperature, there is a problem of poor charging acceptance capacity and insufficient charging.In the low temperature, the insulation and freezing measures should be taken. Especially when charging, it should be placed in a warm environment, which is conducive to ensuring adequate power, preventing irreversible sulfate, and extending the service life of the battery.
10. Prevent short circuit.When installing or using it, you should be particularly careful. The tools used should take insulation measures. When connecting, you should first connect the electrical appliances other than the battery? There is no short circuit after inspection. Finally, the battery is connected.rupture.It is forbidden to use the battery short -circuit method to detect the power of the battery to prevent casualties caused by explosions. When the battery is in a short circuit state, its short -circuit current can reach hundreds of ampere.The more the short -circuit contact, the greater the short -circuit current, so all the connection parts will generate a lot of heat, and the heat is greater in the weak links. It will melt the connection at the connection to generate short -circuit phenomena.The battery may produce explosive gas with explosive gases or when charging, which will cause sparks when the connection is melted, which will cause the battery to explode.The phenomenon, but there will still be overheating in the short circuit, which will damage the adhesive around the connector, leaving it to leave hidden dangers such as leakage.Therefore, the battery must not be generated in short circuit. When installation or use, the tools should be taken specially in insulation measures. When connecting, the electrical appliances other than the battery should be connected. There is no short circuit after inspection.Good insulation, prevent overlapping and stamping.
11. Each start time cannot exceed 5 seconds.Avoid large -current discharge of batteries for a long time, which will greatly damage the internal structure of the battery.It is recommended that the owner cannot exceed 5 seconds each time.It takes two consecutive starts, and it takes 10 to 15 seconds in the middle.
12. To prevent exposure in the sun, exposure in the sun will increase the temperature of the battery, the activity of the active substances of the battery will increase, which will affect the service life of the battery.
13. The battery after discharge should be replenished in time and should not be put on hold for more than 12 hours.
14. Check and adjust the back and forth brakes.Electric bicycles should be checked and adjusted to brake back and forth before use.The front brake is controlled by the right gate, and the rear brake is controlled by the left gate.The adjustment of the front and rear brakes is suitable for reliable brakes when the left and right brakes reaches half of the stroke.
15. Check the lubrication of the chain before using electric bicycles.Whether the chain axis of the feel and observation of the chain is flexible and whether the chain rust is serious.If rust or rotation is not flexible, add an appropriate amount of lubricating oil, and the chain should be replaced seriously.
16. Before the electric bicycle cycling, the tire pressure, the handlebar to the flexibility, the flexibility of the front and rear wheels, the circuit, the battery power, the working status of the motor, and the light, the horn, etc.
17. The standard load weight of electric bicycles is 75 kg, and overload should be avoided as much as possible.
18. Use electric bicycles in cold weather. You should try to help or drive as much as possible. You should also pay attention to the battery instructions and voltage instructions of the battery? Generally, when the weather is cold, the discharge depth of the battery should be appropriately reduced.This is because the battery capacity and discharge capacity of the battery have been reduced when the weather is cold.
19. Electric bicycles should be stored in places where it is cool, ventilated, dry, and far from corrosive liquids and gases. When stored, the vehicle is upright, the tire gas pressure is sufficient, the car body should not be loaded, and the battery should be stored separately.
