You can't go out during the epidemic. How long will your car stop?

From the moment the community notified that it was closed and isolated, Brother K began to worry about his car.

Because counting the days before the outbreak and before the Chinese New Year, Brother K's car has been parked in the garage for almost a month.

So brother k called to ask about the property and confirmed that it doesn't matter as long as he doesn't leave the community.

It's no use leaving the community The road around brother k has been broken? ——?

But now that I can go out, it will be easy.

In the dead of night, Brother K came to pick up his long-lost car, hit it, and then started to go around the underground garage. . .

Drive from negative two to negative one, and then negative one goes back to negative two.

The nearest exit is blocked by a board.

Boring brother K even started timing laps, the same route, faster and faster every time.

Sure enough, practice makes perfect.

It is the common sense of every old driver that the car has been there for a long time without a meeting. So what's wrong with this? Is there any way to prevent him from collapsing?

Today, Brother K will come to talk to the riders about it ~

Speaking of "bad", Brother K thinks the most intuitive thing is the battery, which is what we call "battery".

At present, lead-acid batteries are widely used in family cars, and once the car is parked there, it will produce self-discharge. Under normal circumstances, the self-discharge of the battery every day and night will reduce the capacitance by about 1%.

The key point is that if you don't use it for a long time, the battery will be dead after long-term self-discharge, and the most direct consequence is that you can't get a taxi. Secondly, sulfide will be produced in it, which will affect the recharging effect of the battery. It is very likely that this battery is so useless. . .

Brother k searched for a treasure, and this battery is always a four-digit fee! (Of course, there are hundreds of cheap ones. )

Therefore, when the vehicle is ready to park for more than a week, it is necessary to care about this battery.

There are three solutions, but not every one is suitable for everyone.

One suitable for old drivers is to unplug the negative electrode of the battery.

The principle is simple. My car has completely lost power. How did you lose your strength?

What's more, you can remove the whole battery, take it home and charge it with a 12V charger every few days.

But this method is more suitable for "classic cars", because in newer cars, after the battery is completely cut off, the ECU of the vehicle will stop working, and even if you power on again, a fault code may be given. . .

So what is the next second method? ——? Car charging treasure (also called emergency start power supply)

This thing is actually an upgraded version of the mobile phone charging treasure, with a lot of treasures, cheap two or three hundred and one, good four or five hundred.

Brother k still likes this thing. On the one hand, it is convenient. In case there is really no electricity, you don't have to bother to answer it. On the other hand, this thing can also be used as a mobile phone charging treasure, which is not a waste. . .

Of course, I know that in this special period, many riders say that this thing is good, but what if the courier can't deliver it?

So as a last resort, learn from brother K? ——? Go downstairs for a meeting if you have something to do!

It takes at least 10 minutes to drive the generator to supply power to the battery. Of course, it is also excellent to drive around the parking lot four or five times like Brother K ~

Just be careful not to run out of gas!

When the vehicle is parked for a long time, the lubricating oil on the surface of the cylinder and piston of the engine will contact with oxygen and other corrosive acid and alkali components in the air, which will lead to the deterioration of the lubricating oil film and form a jelly that feels very disgusting.

This gel will make the lubricating oil lose its lubricating function, and the longer it stops, the more serious the deterioration will be.

At this time, when starting the car, the friction between the cylinder and the piston will be in a semi-dry state, which will increase the wear of parts, greatly increase the resistance of starting the car, and make it difficult to start.

There is no good solution to this problem, the only thing that can be done is the same as battery maintenance. ——? Start your car!

Brother K's car hasn't been washed for two months.

It rained every day in Hangzhou years ago, and it hasn't been washed. I thought I would wash it once before the Chinese New Year, but I found it closed, and then there was an epidemic. . .

So a good white car is like this? ——?

Face project can't be lost!

If the car is parked in the open air during this time, ultraviolet light+rain+insect bird droppings+dust+tree sap.

What is the composition of car paint? A large number of resins and metals, these substances determine the characteristics of easy oxidation of car paint.

So the best way is to park in the garage. If you can't, at least dress up and cover the car.

However, Brother K should remind me that it is best to clean the car before parking, otherwise those dirty things are really easy to patina and make thieves sick. . .

I really just want to wash the car now.

A witty rider wants to ask, the fuel car is already so troublesome, what is the loss of electricity?

Isn't the electric car/hybrid car worse?

Brother k doesn't think so.

The analysis of two aspects, on the one hand, is because the owners of electric vehicles who are isolated at home generally have household charging piles at home.

So as long as you can go out, you can run around the underground garage without any scruples.

I'll recharge it when there's no electricity, so don't worry about the dilemma of the fuel car running out of gas.

On the other hand, the battery.

At present, there are two kinds of batteries for electric vehicles, one is lithium battery and the other is nickel-hydrogen battery. The characteristics of these two batteries are different, so the methods of long-term storage are also different.

Because of its own characteristics, if lithium batteries are to be stored for a long time, they must not be parked in a fully charged or empty state, otherwise the battery performance is prone to cliff-like decline, and the cruising range is even more worrying.

Therefore, it is recommended that the battery of your car be kept in the range of 50%-70%.

However, the Ni-MH battery car needs an extra step. Compared with lithium battery, Ni-MH battery has similar performance, but the cost is lower, and the self-discharge efficiency will be more, about 30% per month, and the more full the battery, the higher the self-discharge efficiency will be.

According to this principle, if the Toyota hybrid vehicle does not move for a long time, the power can be maintained in the range of 30%-50% to avoid the battery from being damaged due to high self-discharge efficiency.

Of course, there is one more thing to pay attention to. The power battery of an electric vehicle only provides power and air conditioning. All kinds of electrical components in the car still use 12V lead-acid batteries like gasoline cars.

This means that electric vehicles also need to pay attention to batteries. What's more troublesome is that the battery of 12V is dead, so it can't be started by external force. . .

In fact, in a word, if you can, try to drive your own car and save trouble.

Brother K's friend recently brushed the notice sent by 4S shop in the circle of friends? ——?

I wonder when this epidemic will pass. Brother k is really sick.

I want to drive to eat delicious hot pot, barbecue and kebabs. . .

Forget it, let's have some supper. See you tomorrow!
