What are some precautions when using electric vehicles?

It is strictly forbidden to be in a state of power loss when the battery is stored.

During use, if the driving range of an electric vehicle suddenly drops significantly by more than ten kilometers in a short period of time, it is very likely that at least one battery in the battery pack has a problem.

Electric vehicles are strictly forbidden to be exposed to the sun, and try to choose a cool place to place them.

Check your tire pressure frequently to prevent air leaks and punctures.

Check whether the brakes are sensitive and the battery is sufficient before use.

Dust and dirt should be removed frequently in the motor compartment, and attention should be paid to keeping the battery dry and clean to prevent the battery from discharging itself. When cleaning the whole vehicle, wait for the car to cool down before rinsing, and the water flow avoids the charging socket.

When driving an electric vehicle at the start, carrying people, and going uphill, try to avoid stepping on the acceleration as much as possible, resulting in instantaneous high-current discharge. High-current discharge can easily lead to lead sulfate crystallization, which will damage the physical properties of the battery plates, especially in the case of manned people. 2 3 mileage, charge when you can charge, keep the power sufficient, drive as much as possible to avoid rapid acceleration and rapid deceleration, in order to improve the mileage and ensure that you can drive to the charging place.

Battery maintenance must replenish the power in time after the new car is proposed to keep the battery in a full state. In the process of use, it is necessary to accurately grasp the charging time according to the actual situation, refer to the usual frequency of use and mileage, and grasp the charging time. Overcharging, over-discharging, and under-charging can all shorten battery life.

If it is shelved for a long time, it should be ensured that the power is maintained at more than 80%, because the battery has a self-discharge phenomenon, and the power is too high, which will affect the safety.

Carry out full charge and discharge operation, fully activate the active material in the battery, reduce the capacity reduction and rate discharge capacity and life, some car factories have set up a small current automatic equalization function, and the balancing maintenance should be carried out regularly according to the instructions as required.

Battery use: The vehicle battery is strictly forbidden to be in a state of power loss when it is stored. The state of power loss refers to the fact that the battery is not charged in time after use, and the battery is stored in the state of power loss, which is easy to sulfate, and the lead sulfate crystals are attached to the plate, which will block the ion channel, resulting in insufficient charging and a decrease in battery capacity. The battery of new energy vehicles needs to be stored after sufficient power and replenished once a month to maintain the healthy state of the battery and avoid long-term power loss resulting in sulfation of the battery plates.

The longer the vehicle is idle, the more damaged the battery will be.

Introduction to the precautions for the use of electric vehicles: correctly grasp the charging time.

After proposing a new car, it is necessary to replenish the power in time to keep the battery in a full state. In the process of use, it is necessary to accurately grasp the charging time according to the actual situation, refer to the usual use frequency and mileage, and grasp the charging time by yourself. During normal driving, if the power gauge indicates that the red and yellow lights are on, you should go to charge; If only the red light is on, stop the operation and charge it as soon as possible, over-discharge will shorten the life of the battery.

The charging time should not be too long, otherwise it will form an overcharge and heat up the vehicle battery. Overcharging, over-discharging, and under-charging can all shorten battery life. During charging, if the battery temperature exceeds 65, charging should be stopped.

Periodic deep discharge.

It is also beneficial for the battery to undergo a deep discharge on a regular basis"Activation"battery, which can slightly increase the capacity of the battery. The general approach is to make a full discharge of the battery at regular intervals. The method of full discharge is to ride the bike to the first undervoltage protection under normal load conditions on a flat road.

Note that we place special emphasis on the first undervoltage protection. After the first under-voltage protection of the battery, after a period of time, the voltage of the battery will rise and return to the non-under-voltage state, at this time, if the battery is used again, the damage to the battery is great. After a full discharge, the battery is fully charged.

You will feel that the battery capacity has increased.

Electric vehicles are repaired by maintenance, so consumers should take good care of them when they use them. Hope mine is helpful to you!

1.Charging: The vehicle should not be overcharged and discharged, the most ideal charging time is the battery discharge depth of 50% 70%, it is recommended to charge once a day, so that the battery is often in a shallow cycle state, which can prolong the battery life.

To use 16A special wire to wiring, the charging line should choose the appropriate wire diameter, the line laying should be fixed installation, and short circuit and leakage protection devices should be installed. Long-term use of fast charging will cause battery life to deteriorate, and it is recommended to use slow charging to replenish the battery when there is sufficient charging time. If the electric vehicle is not used for a long time, it should be charged regularly.

2.Parking: Unplug the power cord of the auxiliary battery when it is parked for a long time.

Do not leave it in humidity, high temperature, sun exposure or other environments for a long time. 3.Use:

Before starting the vehicle (before powering on), check that all wiring connections are tight and correct. Make sure the battery is fully charged and avoid over-discharge. When driving, try to avoid sudden acceleration and sudden braking.

If there is an accident such as a crash, first unplug the key, cut off the power, and stay away from the vehicle, and then seek help from the manufacturer or car repair 4S shop.

Electric vehicles are driven by power batteries and motors, and the vehicle is installed with high-voltage power batteries, although all high-voltage cables and joints are strictly implemented in accordance with national and industry standards, users should avoid touching these high-voltage cables and plug-ins, or disassemble and modify vehicle accessories without authorization, so as to avoid safety hazards such as electric shock.

Don't bump back and forth. Don't wait until the battery is depleted to a point before charging. When it rains, push it to a sheltered place.

1. Regular inspection:

If the driving range of a new energy vehicle suddenly drops significantly, it is likely that at least one battery in the battery pack has a problem, and you should immediately rush to the repair shop to deal with it in time.

2. The charging time should not be too long

New energy vehicles should avoid overcharging, over-discharging and under-charging, which will shorten the battery life. In the process of use, the charging time and frequency should be determined according to the actual vehicle situation, if the fuel gauge indicator light is on, it should be charged as soon as possible, otherwise the over-discharge of the battery will affect the life.

And the charging time should not be too long, otherwise it will form an overcharge and make the battery heat. If the battery temperature exceeds 65 during the charging process, the charging should be stopped immediately to avoid danger.

3. Please step lightly at the start:

If the new energy vehicle is accelerated by slamming at the start, it will cause the battery to discharge with high current, and the high current discharge is easy to produce lead sulfate crystals, thereby damaging the physical properties of the battery plate and affecting the service life.

4. Charge well when parked for a long time:

Some car owners believe that if they do not use the vehicle for a long time, they are not worried about the new energy vehicle being parked in a state of power loss, as long as the car is charged before the next use, which is a big misunderstanding. When the battery is stored in the state of power loss, it is easy to sulfate, and the lead sulfate crystals adhere to the plate, which is extremely harmful to the battery.

5. Prevent exposure to the sun and too cold

If the new energy vehicle is exposed to the sun for a long time, the temperature will be too high, which will increase the internal pressure of the battery and cause the battery to lose water, cause the battery activity to decline, and accelerate the aging of the plate; However, if it is stopped in a cold environment for a long time, it will have a sharp impact on the range and will adversely affect the performance of the battery pack.

For the maintenance of transmission oil, antifreeze, tires, rubber parts, etc., refer to gasoline vehicles.

BEVs use an electric motor instead of a gasoline engine and are driven by an electric motor without the need for an automatic transmission. Compared with the automatic gearbox, the motor has simple structure, mature technology and reliable operation.

The traditional internal combustion engine can limit the speed of efficient torque generation to a narrow range, which is why the traditional internal combustion engine vehicle requires a large and complex transmission mechanism; The electric motor can efficiently generate torque in a fairly wide range of speeds, and does not need a gear shift device during the driving of pure electric vehicles, which is convenient and easy to operate, and has low noise.

Compared with hybrid vehicles, pure electric vehicles use a single electric energy source, and the electronic control system greatly reduces the internal mechanical transmission system of the car, and the structure is more simplified, which also reduces the energy loss and noise caused by the friction of mechanical parts, and saves the interior space and weight of the car.

The first thing to consider is the large parts of the car, including: motor, battery, overall frame, plastic shell.

Motor: no bump or deformation of the shell.

Battery: The battery produced in the month of sale is consistent with the brand said by the merchant.

Large frame of the whole vehicle: no desoldering, no deformation, and the paint surface is intact.

Plastic shell: the paint surface is smooth and clean, no scratches, no cracks, positive color, and compact combination.

Precautions for picking up electric vehicles.

Then it's time to look at the key parts of the electric vehicle: controllers, chargers, gauges, lights, tires, brakes.

Controller: Performing well.

Charger: The performance is intact, matched with the battery of the car, and the shell is not damaged.

Gauges: The display is normal, and there are no scratches on the surface.

Lights: complete, correct turn indications.

Tires: no wear, no cracks, correct installation orientation.

Brakes: smart, without brakes, good braking performance.

Precautions for picking up electric vehicles.

Finally, brushless motors are divided into toothless and toothless, with toothless being the majority; According to the working voltage, it can be divided into 36V, 48V, 60V, 72V, and currently 36V and 48V are the majority; According to the phase angle, it can also be divided into 60 degrees and 120 degrees.

Pure Electric Vehicles: Matters of Use.

1. Please put the parking brake handbrake to the end before driving to avoid burning the brake pads or motor.

2. When the red light flashes in the power display, it means that the power has reached the limit, please stop using the vehicle and charge it in time.

3. When the vehicle needs to change the direction of forward and backward, it should be carried out after the vehicle is stopped, and it should be operated in the order of forward gear - neutral gear - backward gear, or backward gear - neutral gear - forward gear. It is strictly forbidden for the vehicle to suddenly change the direction of driving when driving, which is very easy to cause damage to the electronic control and motor.

4. Parking precautions: Release the accelerator pedal and press the brake pedal to brake. Vehicles should be parked on flat roads as much as possible.

Before leaving the vehicle, tighten the parking brake handbrake, put the transmission lever in neutral (the continuously variable vehicle direction switch is in neutral), turn off the electric lock, and remove and take away the key.

Clause. First, the early attack of electric vehicles is a very good means of transportation, but electric vehicles also have a big problem, that is, electric vehicles need a long time to charge, so we should pay attention to the length of charging time when choosing electric vehicles, and the long time is naturally not suitable for family use.

Clause. Second, the electric car is an environmentally friendly car, and the purpose is to drive in the city. Therefore, if you want to go on the highway, it is recommended that you still do not buy an electric car, because after the highway, the electric car must reach the specified speed, which will seriously affect the battery life of the electric vehicle.

Clause. Third, the driving habits of electric vehicles are different from our general car driving, it seems that electric vehicles are more simple and laughing, in fact, electric vehicles have only one gear, because the motor consumption of the car is very large, not suitable for full load driving, we must pay attention.

Clause. Fourth, the purchase of electric vehicles must pay attention to the battery position of the electric vehicle, because the placement of the battery slag contains the position, related to the space of the car, if the battery position is unreasonable, then the car will be greatly affected, so this aspect must be noted.

Clause. Fifth, the air conditioning system of electric vehicles must be carefully checked, because the air conditioning power of electric vehicles is too large, which will directly affect the mileage, which is also the reason why many people find that the mileage is very problematic after buying an electric car, so when buying a car, you must fully test drive!

1、Choose and use qualified electric bicycles produced by regular manufacturers, charger and battery, regular maintenance, unauthorized modification is strictly prohibited.

2. Electric vehicles shouldPark in a safe placeIt is strictly forbidden to park in stairwells, evacuation passages, and safety exits, and shall not occupy fire truck passages.

It is strictly forbidden to charge in corridors, stairwells, evacuation passages, etcCharging should be carried out outdoors, making sure that there are no combustibles around, and charging at a centralized charging point as much as possible.

In the summer when the temperature is high, try not to use the electric car continuously for a long timeto prevent circuit failures caused by factors such as high line temperature and motor heating.

Shanghai issued the "strictest new regulations for non-motor vehicles":

From May 1, 2021, the "Shanghai Non-motor Vehicle Safety Management Regulations", known as the "most stringent new regulations for non-motor vehicles", came into effect.

The regulations stipulate that electric bicycles are prohibited from parking and charging in public common areas such as foyers, public walkways, stairwells, and corridors on the first floor of buildings, as well as evacuation passages. Where illegally parking or charging, a fine of between 1,000 and 10,000 RMB is to be given, and where the circumstances are serious, a fine of between 10,000 and 50,000 RMB is to be given.

Electric bicycles are a new type of bicycles, which have the same and great differences in use as bicycles, and we will explain in detail the precautions in the use of electric bicycles.

1.The mileage of the electric bicycle is determined by the lead-acid battery used, the general mileage of the 24V, 12Ah battery pack is 25 30 km, which can meet the needs of users within 20 km of the daily commuting distance, and users above 20 km Please choose the 36V, 12Ah battery pack.

2.The maximum speed of an e-bike is less than 20 kilometers per hour when it is driven entirely on electricity, and it should be driven in a bicycle lane to ensure safety.

3.The electric bike accelerates quickly, in order to ensure your safety, please start the motor after the ride is stable, so as to avoid you being in a hurry in the traffic flow, do not start on the spot.

4.When the battery is fully discharged (the controller protection circuit works, there is no current output), it takes 3 to 5 hours to fully charge, and it is better to charge the battery for a few more hours, so be sure to choose a high-quality charger.

5.The acceleration handlebar of the electric bicycle sometimes cannot be fully returned, please develop a good habit of pushing the handlebar back after the acceleration is completed.

6.When braking, the current of the motor is cut off at the same time, so there is no need to worry that the motor will continue to rush forward when braking; But once the brake is released, if the accelerator handlebar is still in the acceleration position at this time, the motor will immediately get the current forward, if you don't want this phenomenon to happen, please develop a good habit of pushing the handlebar back after the acceleration is completed.

7.Before each use of the electric bicycle, you should check whether the tire pressure is sufficient, whether the handlebar steering is reliable, whether the brakes are flexible and effective, whether the electrical socket and plug of the battery box are loose, and whether the battery box is locked.

8.E-bikes are not suitable for driving on uneven or steep roads, so get off the bike and push them out of the car if you encounter such roads.

9.When riding in winter, please try to use full pedal assistance, which can not only make your body workout, not let your legs and feet be frozen, but also help to prolong the service life of the battery (because the low temperature reduces the capacity of the battery pack, the same riding distance, the depth of discharge increases).

10.E-bikes are designed to carry a load of 100 kg, so please do not bring people and objects that are too heavy.

11.Although the electric bicycle has good rain resistance, please avoid direct sun and rain.

12.The seat height of the electric bicycle is subject to the rider's feet on the ground to ensure safety.

13.In the event of an emergency breakdown (e.g. brake failure), try to get out of the vehicle quickly and put the vehicle down.

14.The lead-acid battery used in the electric bicycle is a consumable, its life is only 1 2 years, and the length of life has a great relationship with the daily use and maintenance of the user.

1) The smaller the depth of discharge of the battery each time it is used, the longer the service life of the battery, so no matter how large the capacity of the battery pack is used, users should develop a good habit of charging at any time.

2) When the battery needs to be placed for a long time, it must be fully charged and replenished regularly, generally every 1 3 months.

3) High-current discharge can damage the battery to a certain extent, so please use the pedals to assist when starting and going uphill.
