How to protect the battery and motor of electric vehicles

How can I use it to extend the life of my battery? 1. When the electric vehicle is on the bridge, climbing, or driving against the wind, it should be supplemented by manpower drive to prevent the battery power supply current from increasing sharply; 2. When you just get on the car to ride, or when you want to ride after emergency braking and stopping speed during driving, it is best to pedal a few times with your feet, and then ride electrically after the electric vehicle has a certain speed. Try not to make the electric vehicle directly start with electricity in a stationary state; 3. When you need to accelerate while riding, you should slowly rotate the speed regulator to avoid accelerating directly to the fastest gear.

Not only does this not immediately increase the speed of the vehicle, but it also generates an inrush current that can cause damage to the battery. As far as the road conditions allow, keep the electric vehicle at the highest speed as much as possible; 4. In riding, try to avoid frequent braking and starting, and use pedals to drive when the road is congested. This not only increases the "driving range", improves the efficiency of the battery, but also prolongs the service life of the battery; 5. Charge frequently, so that the battery is often in a full state, and users with conditions should be charged at any time; 6. If you are not ready to use it for a long time, you should store the battery after it is fully charged, and replenish it regularly (1 month); 7. The power shows that the battery is out of power, and after a period of time, you will find that the battery has a small amount of voltage, which is called "recovery voltage".

The user should not use this "ramp-up voltage" to drive.

Typing is not easy, such as satisfaction, hope.

Then you have to choose Xupai, and the product sales are all over the domestic market;

Of course, it can be used, and timely maintenance of the battery can also extend the life of the electric vehicle.

1. The life of the original battery of the battery car is generally between two and three years, and the specific replacement depends on the use.

2. According to the normal use and maintenance, there is basically an approximate time for how long the electric vehicle battery will be replaced, but when the following phenomena occur, it can also be judged as the end of the battery life.

3. When the battery is charged, the heat is serious. At the end of the life of the battery, the positive electrode will be seriously softened, the active material will fall off, the internal resistance will increase, and the impurity elements in the plate will continue to dissolve, so that the gas separation will increase during charging, the efficiency will deteriorate, and the heat generation will increase. At this time, if you open the battery safety valve to check, you will see that the electrolyte is black, and it cannot be repaired when it fails seriously.

4. During the use of the battery, the capacity gradually decays, and the performance gradually declines until the end of its life, and the battery needs to be replaced when it fails to meet the user's requirements. In addition to knowing how long the battery of the electric vehicle is replaced, in order to ensure the reliability of the operation, it is also necessary to pay close attention to the operation status of the battery and replace the battery in time.

5. The battery at the end of its life has a significant decline in various properties, and the performance is extremely unstable, which may cause adverse consequences: such as charging heating and deformation, short circuit, open circuit, and even danger.

Under normal circumstances, the battery is guaranteed to be replaced for 15 months, the first 8 months for free, the first 12 months for free turnover, the first 15 months for maintenance, your situation is likely to be 4 batteries one of the broken, if you change the maintenance, it is better to let him give you a piece of production date close to the maintenance is not recommended for you to change the maintenance, it is better to negotiate the merchant, paste about 100 yuan for a new one.

If you're cheap, there's no way to say that.

1. Batteries are divided into original batteries, turnover batteries and maintenance batteries. Generally, the new battery can be replaced after the warranty is over, the warranty period of the turnover battery is 6 months, and the maintenance battery can also be replaced after the warranty, and the warranty period of the maintenance battery is relatively short, generally 3 months.

Second, it is precisely because of the low maintenance battery level and small battery capacity that its durability will become lower after maintenance, charging and discharging. The original car battery can generally be used for more than 2 years, if there is no problem with the original car battery, it is recommended not to replace the maintenance battery.

Third, the original car battery has good balance, and the discharge time is also within the standard time, which is more durable, which is incomparable with the maintenance battery.

The maintenance battery is a turnover battery, which can be used, but it will not be used for too long.

It is charged once every three days, and it is guaranteed to be finished in 6 months.

1. The newly purchased Sen Shen Mo electric vehicle should be fully charged before use. Because many electric vehicles have been shelved in stores for several months, or even more than half a year, they must be fully charged before use, and it is best not to use them immediately after sufficient power, but to stand for about ten minutes.

2. Take down the battery to charge, and when installing, the battery should be installed firmly on the electric bicycle to prevent the battery from being damaged by vibration when riding.

When the battery is transported, it is forbidden to throw, roll over, or weigh hard.

3. Frequently remove the dust and dirt on the battery cap, and pay attention to keeping the battery dry and clean to prevent the battery from discharging itself.

4. The battery must not be in a state of insufficient power for a long time, and it is necessary to develop the habit of charging the battery every night. If you don't use this for a long time, you should fully charge it, place it in a cool and dry place, and charge it regularly (usually 10 days).
