1. Precautions for battery installation.

1. Before installing the battery, check whether there are any hard objects in the battery box or whether the battery box is flat.

2. When installing the battery, the battery wires should be arranged separately and cannot be overlapped or squeezed. The battery wires carry a large current of the entire vehicle and will generate heat during operation. After the battery wires are squeezed, the outer skin is easy to wear, reducing the Insulating properties, causing short circuit and burning.

3. When connecting the battery wire, you must install a spring washer and tighten the screws at the same time to ensure that the battery terminals are not loose to avoid sparking during use, high temperature burning of the battery wire, and short-circuit burning.

4. After connecting the battery, cover it with a rubber pad. When placing the battery to press the wires, separate the battery wires with your hands so that they cannot cross or overlap, and tighten the screws at the same time.

Be careful not to use cardboard, foam and other flammable materials instead of rubber pads, or put them into the battery box as fillers.

5. When installing the battery, if you loosen the air switch connecting wire in the seat bucket, after installing the battery, the two connecting wires of the air switch must be connected properly and cannot be loosened to avoid catching fire and burning the car. .

6. After installing the battery, when installing the seat bucket, the inner lid of the seat bucket should be closed. Metal objects should not be placed in the bucket to prevent metal objects from falling into the battery and contacting the positive and negative terminals of the battery. If touched, it will cause a short circuit and burn the car.

7. You cannot install a single battery without permission (48V plus 1 battery becomes 60V), etc. When the battery voltage rises, internal components such as converters, controllers, and anti-theft devices cannot withstand the high voltage, and the components will burn out and cause short circuits, causing combustion. Install a single battery; the battery is easy to be turned upside down, and it is easy to leak and damage the battery grid during charging. The battery may short-circuit and heat, causing the battery to catch fire.

8. The battery loses water severely. When charging, the battery will heat up and bulge. The high temperature will burn out the battery wires and cause short circuit burning.

9. Do not use low-cost, low-quality batteries. In order to reduce costs, low-quality batteries do not have burrs. The burrs pierce the separator, short-circuit and heat, causing the battery to malfunction.

2. Precautions for charging electric vehicles.

1. When charging, the charger will generate heat, and the battery will also generate heat. You should choose a good ventilation environment. If the ventilation conditions are too poor, short circuit burning may occur due to overheating.

2. When charging, the charger should be placed at the footrest. It is strictly forbidden to cover it with objects or place it on the seat cushion or in the seat bucket.

3. When the charger is carried in the car, there is no shockproof protection. Long-term vehicle bumps will cause the power components to desolder and catch fire during operation. It is recommended not to carry the charger with you in the car.

4. After the charger is dropped or collided, the fan is easy to break. When charging, you should observe whether the charger's cooling fan is operating normally. If the fan is broken, repair it in time or replace it with a new charger.

5. The charging time is 8-10 hours. Do not charge the electric vehicle for a long time, especially in hot summer weather. If you charge for a long time, the heat of the charger will be difficult to dissipate and cause combustion.

6. When charging, the power cord is lengthened at will and often pulled around, resulting in loose connectors, aging circuits, damaged wire rubber, short circuits, and fires.

7. When charging, the electric door lock must be turned off. If the electric door lock is turned on and the charging battery voltage rises, the electric door lock will be burned out and cause a short circuit and fire.

8. Qualified flame-retardant wires should be selected when charging, and the lines should be equipped with leakage protection devices.

3. Precautions for electric vehicle maintenance.

1. After the electric vehicle is repaired, be sure to connect the controller, power cord, and motor cord, and tie up all wiring harnesses with nylon ties to ensure that the plugs are not loose.

2. Electric vehicles cannot be handed over to maintenance workers who have no maintenance experience.

4. It is not allowed to modify or install vehicle wiring without permission.

1. Merchants or users privately modify the vehicle wiring. The modified wiring and wires are not flame-retardant, the wiring is messy, the wrapping is not tight, the joints are easy to loosen, the contact is poor, the internal resistance of the wires increases, and they will burn for a long time. Bad wires cause poor insulation and cause short circuit burning.

2. Merchants or users privately install vehicle wiring, such as installing higher-power light bulbs, speakers, subwoofers, etc., which increases the output load of the converter and easily burns out the internal components of the converter. Cause short circuit burning.

5. Do not use high-pressure water guns to flush the interior of the electric vehicle to avoid short circuiting the internal circuits.

Before traveling, you should check whether the tire pressure is sufficient. If the air pressure of the tire is very sufficient, it will be able to avoid the occurrence of tie-ties. If the electric vehicle is tied on the road, it will be very passive. The way to check is to park the car properly, and then press the tire with the thumbs of both hands. If it can be pressed, or even a lot, then it is time to use the air tube to inflate; if it cannot be pressed, or it cannot be pressed very much, , indicating that the air pressure is sufficient and can be used normally.

When traveling in winter, be sure to keep warm. In other seasons, the weather is not very cold, so the situation will be much better. Sometimes the weather is very cold when traveling in winter. Cycling to work will freeze your face, hands and legs, so it is best to wear a hat, scarf or mask. You can wear cotton gloves on your hands and a cotton windshield on your legs. . With these equipment, it is not only conducive to keeping warm while traveling, but also conducive to travel safety.

When traveling in winter, pay special attention to the ice on the ground. Ice on the ground makes it very easy to slip, and people often fall in such conditions. The prevention method is to slow down your vehicle when it is icy, don't brake, and pass slowly. If there is a car next to you, don't pass it at the same time to prevent the car from sliding and injuring you or knocking you down.

Pay attention to the small animals on the street. Small animals on the street sometimes suddenly emerge from the street or from the side. In order to avoid the small animals, people often fall down, or traffic accidents occur. This kind of situation is difficult to prevent because it is sudden, but you should improve your safety awareness and don't ride too fast. If you encounter such a situation, you will have enough time to brake or stop, so that the car will not lose balance. And fell down and got hurt.

obey traffic rules. It is important to obey traffic rules. Pass when the light is green and stop when the light is red. At night, some motorcycles have no lights and are usually very fast. When he sees the green light, he will pass quickly, but he thinks that there is no car and runs the red light to pass. This is very dangerous. Therefore, when traveling, you should develop a good habit of obeying traffic rules. This will greatly improve your own safety awareness and personal safety.

Please pull over when driving on the road at night. It is very safe to pull over when driving on the road. Cars are traveling very fast and injuries are often very serious. And when driving on the side, try to keep a straight line. If a motorcycle comes out from behind, a traffic accident may easily occur.
