The electric rear ring is a pit, and the car is out of gas, is it a flat tire?

Yes, it is possible that the outer tire bites the inner tube.

Inflate the try, if you can't fill it up, it's bursting, if the leak is faster, it's pricked, and the leakage is slow (it takes a day or two to see the leakage) is also pricked, but the hole is relatively small, and it's not easy to check.

Did you hear a sound when you were out of gas?

Check the front of the tire for nails or something, ** can't be seen.

Judging from the appearance, 90% of them are flat tires, so quickly pull them to the maintenance office for repair.

Anyway, it's out of gas! It's all about repairing.

Sprinkle the ghost place that sent the third party.

Hurry up and push it to the place where the car is repaired and let the master take a look.

The rear tire of the battery car is a puncture.

Check the vacuum nozzle. See if it's rotten, if it's broken, it is recommended to replace it.

If the electric car is not ridden for a long time, the tires will leak. This is because no matter how good the density of the tire is, it also has a gap, and no matter how good the valve core of the tire vent is, it also has a gap, and it will naturally leak after a long time.

Battery car tubeless.

If you don't have gas, you can't continue to ride, because the vacuum tire has no inner tube, if you continue to ride, the outer tire and the ring will fall off and separate, and it will be difficult to push at that time.

Note to change the Pulse Matters:

1) "Vehicle" refers to motor vehicles and non-motor vehicles.

2) "Motor vehicle" refers to a wheeled vehicle that is driven or towed by a power unit and driven on the road for personnel or for transporting goods and carrying out special engineering operations.

3) "Non-motorized vehicle" refers to a vehicle driven by human or animal power on the road.

and motorized wheelchairs and electric bicycles for the disabled that are driven by power units but are designed to meet the relevant national standards in terms of maximum speed, empty mass and dimensions.

and other means of transportation.

Battery car tubeless.

It will have a flat tire and will not exhaust on its own.

Causes of puncture: Tire leakage, tire pressure is too high, tire pressure is insufficient, tire "sick work".

Puncture prevention: 1) Priority is given to radial tires.

Tubeless tires.

The radial tire carcass is softer, and the belt layer is made of fabric cord or steel cord with high strength and small tensile deformation, so this kind of tire has strong impact resistance, low rolling resistance, and less energy consumption, which is most suitable for driving on the highway.

Tubeless tires have small mass, good air tightness, low rolling resistance, and in the case of tire perforation, tire pressure.

It will not drop sharply and will continue to drive completely. Since this tire can pass directly through the rim.

Heat dissipation, so the working temperature is low, the tire rubber aging speed is slow, and the life is relatively long.

2) Use low-pressure tires whenever possible.

At present, almost all cars and trucks use low-pressure tires; Because the low-pressure tire has good elasticity, wide cross-section, large contact surface with the road, thin wall and good heat dissipation, these characteristics improve the driving smoothness and steering control stability of the car, greatly prolong the life of the tire, and prevent the occurrence of car puncture.

3) Pay attention to speed level and carrying capacity.

Each type of tire has different speed and load limits due to different rubber and structure. When choosing tires, the driver should see the speed level signs and carrying capacity signs on the tires, and choose tires that are higher than the maximum driving speed and maximum carrying capacity of the vehicle to ensure driving safety.

4) Maintain the standard air pressure of the tire.

The life of a tire is closely related to air pressure. If the driver finds that the tires are overheating due to high air pressure, it is absolutely not allowed to use the method of deflating and pouring cold water on the tires to reduce the temperature, which will speed up the aging of the tires. In this case, you can only stop the car for natural cooling and pressure reduction.

For tire pressure too low, the driver should inflate in time and check whether the tire is slow to deflate, so as to replace the tire with good air tightness.

Measures to deal with punctures: Do not brake suddenly, and slow down slowly. Because the sudden puncture of the car at high speed will cause the vehicle to deviate sideways, and sudden braking will make this side deviation more serious, resulting in overturning. Slow down while keeping your hands on the steering wheel.

Turn in the opposite direction of the puncture to keep the vehicle running in a straight line.

In fact, the battery, in addition to the need for ventilation, also needs to be opened. However, one point is often overlooked:

1) Waterproof: Block electrolyte leakage;

2) Breathability: release the gas generated during the working process of the battery, balance the pressure difference between the inside and outside of the battery shell, and prevent **.

3) Dustproof: Prevent external dust, pollen and other particles from entering the battery case to improve the service life of the battery.

The EPTFE (a microporous waterproof and breathable membrane) has such a function (it can not only be waterproof and dustproof, but also exhaust to prevent excessive pressure inside the battery, that is, to balance the pressure and prevent **), which is generally connected to the battery shell by welding or adhesive.
