The use and maintenance of four wheeled electric scooters

Summary. How to go from high speed to low speed? Let's talk about it here.

The specific operation is: first press and hold the brake, turn the speed control handle to the bottom, open the power lock, and then do not release the brake, but turn the speed control handle 3 times in a row, and finally let go of the speed control handlebar, let go of the brake, so that the speed can return to the speed limit state.

However, users need to note that the above three methods are for conventional models, and due to the restrictions of the new national standard, many new national standard models have been added to the anti-tampering setting, which means that the speed limit problem cannot be solved only by adjustment, and for such models, it is necessary to rematch the motor, controller, and battery, but it is not recommended that you do this, because the cost is too large, and it is a violation.

If the new electric vehicle cannot run fast, you can try the above three methods to solve the speed limit. Of course, if you can't solve it yourself, you can also ask the maintenance master to help.

How to regulate the speed of the elderly four-wheeled electric scooter.

First hold down the brake, turn the speed control handle to the bottom, turn on the power lock, and then don't let go of the brake, but turn the speed control handle 3 times in a row, and finally let go of the speed control handlebar, let go of the brake, so that the speed can return to the speed limit state. However, users need to note that the above three methods are for conventional models, and due to the restrictions of the new national standard, many new national standard models have been added to the anti-tamper setting, which means that it is impossible to solve the speed limit problem by relying on adjustment alone, and for such models, it is necessary to rematch the motor, controller, and which number of batteries, but it is not recommended that you do this, because the cost is too large, and it is a violation of the suspicion of delay. If the new electric vehicle cannot run fast, you can try the above three methods to solve the speed limit.

Of course, if you can't solve it yourself, you can also ask the maintenance master for help.

I hope the above changes will be helpful to you, and I wish you a happy life and repentance

New regulations for four-wheeled scooters for the elderly:

1. The length of the body does not exceed 3500mm, the competition does not exceed 1500mm, and the height does not exceed 1700mm.

2. The maximum speed of the vehicle within the driving range of 1km should be greater than or equal to 40km h and less than or equal to 70km h.

3. The curb weight of the vehicle does not exceed 750kg, and the power battery should not exceed 30% of the weight of the vehicle.

4. Speed warning, when the vehicle is lower than 20km h, it should be able to send an appropriate reminder sound to the people outside the vehicle.

5. The maximum climbing degree is not less than 20%.

6. The acceleration time of the vehicle from 0 to 30 km h should not be more than 10 seconds.

Precautions for using old scooters:

1. Check the water level of the old scooter.

2. Close the cap of the exhaust port tightly before charging.

3. Don't overcharge. Overcharging can lead to the generation of a large amount of gas (water consumption), heating and aging of the battery.

4. Don't undercharge. Undercharging can cause the battery to passivate.

5. Do not charge frozen and solidified batteries.

6. Avoid charging the old scooter at a temperature above 49.

7. The battery should be charged no matter how many kilometers it travels after daily use.

8. Confirm that the charger is fault-free (the voltage is set correctly).

9. Equalize charging every three months to six months, and charge for 1-2 hours each time. The extension of the life of the old scooter is mainly for the protection of the battery, and the standardization of the method of using the old scooter, which is particularly important.

Summary. Hello, pro, the elderly four-wheeled electric scooter speed regulation is as follows: replace the power battery with better performance, match a larger current controller, which will also increase the cost, therefore, as only for the elderly and ordinary families to travel short distance of low-speed electric vehicles, whether from the product positioning or from the market demand, there is no need to improve the speed of this type of model, and, according to the current manufacturing process, if the speed is increased, the safety of this kind of low-speed electric vehicle is also difficult to guarantee.

It is advisable not to increase the speed!

Hello, dear, the elderly four-wheeled electric scooter speed regulation is as follows: replace the power battery with better performance, match a larger current controller, which will also increase the cost, therefore, as only for the middle-aged and elderly groups and ordinary families for short-distance travel to talk about low-speed electric vehicles, whether from the product positioning or from the market demand, there is no need to improve the speed of this type of model, and, according to the current manufacturing process, if the speed is increased, the safety of this kind of low-speed electric vehicle is difficult to guarantee. It is recommended that you do not increase the speed of the dismantling!

The first type: first do not turn on the power, pinch the brake handle, turn the speed control handle to the end, immediately turn on the power, continue to rotate the speed control handle to the maximum grip tremor limit 3 times in the state of pinching the brake handle, and hold the speed control handle to the end for 5 to 8 seconds for the third time, and unlock it successfully. The second:

Regardless of whether it is a full-speed or a speed-limiting state, in the state of turning off the electric lock, pinch the brake handle at the same time, turn the speed control handle to the bottom of the block, and then open the electric door lock, keep the speed control handle to the end and brake for 3-5 seconds, and enter the full speed state.

Dear, I am glad to answer your question about the speed regulation method of the elderly four-wheeled electric scooter Electric four-wheeled vehicles generally have three forward gears and one reverse gear. When you first start, you should slowly accelerate from the first gear, and then gradually change to the high-end position, and you must not send a code to hang the second or third gear, let alone slam the accelerator. In order not to cause excessive tranquillity current.

Four-wheeled family battery car with different gears: generally divided into 1st gear, 2nd gear, 3rd gear, 1st gear is the smallest speed, and the further down the speed, the faster. If it is a family four-wheeled battery car with integrated braking and acceleration:

The accelerator is the faster it goes down, and it is the fastest speed to step on it. Usually when using a family four-wheeled battery car, just start from the minimum speed of the attack to drive slowly, do not add to the fastest speed, it is easy to accelerate too fast to cause the family four-wheeled battery car to lose control, especially when the elderly use to pay attention to the correct speed regulation.

Summary. Hello, happy to answer your <>

How to regulate the speed of the elderly four-wheeled electric scooter.

Hello, happy to answer your <>

Lao Chang ordered the method of speed regulation of the four-wheeled electric scooter: 1Don't turn on the power in the first place.

2.Pinch the brake handle, turn the speed control handle to the end, and turn on the power immediately. 3.

Under the state of pinching the brake handle, continuously rotate the speed regulation handle to the maximum of 3 times, and keep the speed regulation handle to the end for 5 to 8 seconds in the first three times, and the speed limit is successful.

How can an elderly four-wheeled scooter reach a speed of 20 yards per hour, but how can it become a 30 yard per hour? The above reply I have already seen it on the top and tried it, but it doesn't work.

Kiss, you need to use the computer to brush the controller program.

Expansion: Definition of four-wheeled electric scooter for the elderly: mainly used for daily shopping of elderly cars, the speed of this cover is generally not higher than 10km per hour, and electric vehicles, the power of this kind of car comes from battery power, but it is relatively cheap.

Refers to the four-wheeled low-speed electric vehicle, which is similar in appearance to electric vehicles, the size of the state is smaller, the driving speed is relatively slow, and the driver is the elderly.

1. Don't replace the charger casually, and don't remove the speed limit of the controller. Chargers from various manufacturers generally have individual needs, so don't change them when you're not sure. If the driving range of the control computer board is relatively long, and it is necessary to equip multiple chargers for charging in different places, the charger that is supplemented during the day is used as a separate charger, and the original charger is used at night.

Removing the speed limit of the controller, although the chain can increase the speed of some cars, in addition to reducing the safety of the car, it will also reduce the life of the battery.

2. Protect the charger. The general instruction manual has instructions on protecting the charger. Many users do not have the habit of reading the manual, and often only think of looking for the manual to read after the problem, often it is too late, so it is very necessary to read the manual first.

In order to reduce costs, chargers are basically not designed with high vibration resistance, so chargers are generally not placed in the trunk and basket of electric bicycles.

3. Charge every day. Even if you don't have a long battery life and can last 2 to 3 days on a single charge, it is recommended that you charge it every day so that the battery is in a shallow cycle state and the battery life will be extended. Some early mobile phone users think that the battery is best to be charged after it is basically used, this view is not right, and the memory benefit of lead-acid batteries is not so strong.

4. Frequent discharge has a great impact on the life of the battery. Most chargers may charge 97% to 99% of the battery charge after the indicator light changes to indicate that the battery is fully charged. Although only 1% and 3% of the power is undercharged, the impact on the continuation ability is almost negligible, but it will also form an undercharge accumulation, so after the battery is fully charged, it is also good to continue to float charge as much as possible after the battery is fully charged.

5. Charge in time. The vulcanization process begins after the battery is discharged, and within 12 hours, there is a noticeable vulcanization. If you do not charge in time, these vulcanization crystals will accumulate and gradually form coarse crystals, and the general charger is powerless against these coarse crystals, and will gradually form a decline in battery capacity, which shortens the service life of the battery.

Therefore, in addition to charging every day, it is also necessary to pay attention to charging as soon as possible after use, so that the large battery in front of the chain is in a full state as much as possible.

Hello dear, <>

I'm glad to answer for you, the old four-wheeled electric car has Yamaha's four-wheeled electric sedan, this car can reach a top speed of 80 kilometers per hour, in addition, there is also a Huanyu electric car is also this type of model. The old scooter can also be called the elderly electric vehicle, which is divided into two types: three-wheeled electric vehicle and speed-wheeled electric vehicle, which is a tool for the elderly to travel outdoors. In the old Qing bucket era, the xing energy cousin of the scooter is relatively stable, and the speed is relatively slow.

Old-age scooters are mainly composed of lead-acid batteries, lithium-ion batteries, fuel cells, etc., which convert chemical energy into electrical energy to provide power for electric vehicles. The old scooters do not need to apply for a driver's license and license plate to drive on the road, and the motor commonly used by the elderly is generally a DC motor, with a motor power between 400 watts and 900 watts. <>
