How to charge the electric vehicle battery is the most reasonable charging time and charging time

Many of my friends I know think that electric vehicle batteries should be charged at any time, no matter how many miles they run a day, no matter how much the battery is used, they should charge the battery when they get home from work, and then unplug it the next day. In this way, although the battery is always fully charged, long-term use will definitely reduce the life of the battery.

First of all, don't be too lazy. Don't wait until the battery is out of charge to charge. In particular, after the battery is used up, the voltage rises again after stopping for a period of time, which is called "rising voltage", and working with the rising voltage will cause irreversible damage to the battery.

Therefore, you must not run away with the pick-up battery, if there is no power on the road, it is best to close the power supply and rely on your own physical strength to drive!!

Also, you can't be lazy when charging. It doesn't matter if you can't charge it, it can be charged overnight, or even for a day. What would it feel like if you were full and let you eat, and in the long run, your stomach would be finished.

The same is true for the battery, which cannot be charged for too long, and will be charged for a long time. Generally, after the charger indicator changes color, recharge for another 2 hours. Charge it a little later in the evening and unplug it immediately after waking up the next day; Or charge earlier, remember to unplug the power supply when you get up at night to pee.

In fact, if you put more effort into making a living, you will be able to better protect your belongings and save a lot of expenses ......

Secondly, don't be too diligent. The charging frequency should be determined according to how much you run each day and the battery condition, and the number of charging times should be minimized under the condition of ensuring normal driving the next day. Generally, it is necessary to grasp the use of battery power.

Recharge when six or seven percent.

It is best to charge the EV charger when the battery level is shown at a third level, and it is best not to put the charger on the car, as long bumps in the driving process can damage the EV charger.

1. Charge when the battery indicator shows one-third of the remaining power.

2. The charging environment should be kept dry and tidy, and the charger should not be wrapped in plastic bags or plastic bottles, because it is easy to burn when the charger cannot breathe.

3. Try not to use fast charging, if it is not necessary, do not use it more than twice in a month.

4. The charger should be placed in a fixed place, do not bump, and even if it is carried, it must fully consider the failure caused by bumps.

5. Use the standard EV charger for charging.

The charger currently used has not been completely de-energized after the charging is completed, and the battery is often overcharged, so at the same time, it is necessary to charge more and charge less. I'll tell you a trick. First of all, under normal circumstances, pay attention to how long it takes to charge for a day of riding.

Charge it immediately after returning home at night, just full before going to bed (time), charge it when you go home, and reduce it before going to bed, so that there will be no overcharging. Charge when you sleep, just full when you wake up, and charge at this time in the future. If you run a lot one day and run out of power, you can charge it 8-9 hours before getting up, and the next day you use it, under normal circumstances, the electric car will not charge for more than 8 hours.

A good way to charge is to charge it for another 1 or 2 hours after replacing the green light.

The battery life is calculated by the number of charge and discharge, and the lead-acid battery is about 350 times. However, the number of charging and discharging mentioned here should be the number of times the charging is completed, and it cannot be considered that the usual charging is a single charge. In this regard, you can rest assured that a set of batteries has been used for more than two years.

So first of all, it is understandable that many owners of electric vehicles charge their cars in this way. In the end, even if the electric range of ordinary electric vehicles is full, it will be about 40 kilometers, so it cannot be inevitable with motorcycles. And, if you run out of electricity, it takes a long time to recharge, usually a few hours, and you can't just run out of gas and go like a motorcycle.

The power of electric vehicles has "uneasiness", so many car owners choose to charge every day to keep the power as much as possible, but you must know that this is the lead-acid battery used by most electric vehicles. The number of charge-discharge times is actually limited, so charging too often will shorten the life of the EV battery. If it is always charged every day, after a long time, the battery will have various problems.

But running out and recharging is not entirely the right way either. Charging the battery of an electric vehicle completely clean will cause some damage to the battery. If you are in a state of power loss all the time, the life of the battery will also be adversely affected, and it is quite difficult to run out of power just now.

If you really want to do this, it is easy to have an embarrassing situation of not being powered in the middle. Carter would be quite angry. It may affect work cards or other work efficiency.

Therefore, the experienced mechanic finally pointed out that the correct way to charge is to judge whether to charge or not based on the remaining power of the battery. Due to accuracy and battery aging, charging generally needs to start when the power displayed on the EV meter is about one-third lower.

Electric cars are also not good if they are charged frequently.

The correct way to charge should be to charge once a week when the electricity consumption is 10%. When the power consumption exceeds 40%, it can be charged once a day, and it can be charged for 6 hours.

And when the electric vehicle is not used for a long time, the battery should be fully charged in advance, and it is recommended to replenish the battery in two or three months.

No, if you charge it often, it will cause damage to the battery, and the correct charging method should be to charge the electric car after the power is used up.

It's not good, and when you see that the battery is about to run out, you should charge it in time at this time, and then the charging time should not be too long, and it should not exceed 12 hours.

I don't think electric cars often charge well because that reduces the life of the battery. I think we'll charge the electric car when there's one bar of power left.

Of course, it is not good, if you charge it often, it will damage the life of the battery, and the most reasonable charging method is to charge it only after about 1 3.

The correct way to charge an electric car is:

1. Charge if you use it, don't charge it if you don't use it, 2. Charge more with more, charge with less with less, charge when you run out, 3. Charge once a day.

At present, the vast majority of electric vehicles use lead-acid batteries, lead-acid batteries are normally full batteries, theoretically speaking, they should be charged immediately, but the charger is not suitable for carrying with the car, so it is not easy to realize the use and charging; And because it is a normally full battery, it must be fully charged as soon as possible after use. Therefore, combined with the characteristics of people's activities, electric vehicles should generally be charged once a day as long as they are used, so that all aspects can be taken into account.

1. The charging time of an electric vehicle is about 5-10 hours.

2. When the charging indicator turns from red to green, it means that the battery is fully charged, at this time, if time allows, it is best to continue charging (floating) for about a few hours, so that the battery can get more energy.

3. However, the continuous charging time should not exceed 12 hours, otherwise it is easy to cause deformation and damage to the battery.

Electric vehicle charging is generally charged for 8 10 hours as well, do not exceed 10 hours, so as not to cause damage to the battery and charger, reduce its service life, in addition, it is best not to deliberately ride to the state of power loss before charging, when the power is left 20% to charge in time. Most electric vehicle batteries are lead-acid batteries or lithium batteries, and if they are charged for too long, they will cause damage to the battery, and the battery is prone to thermal runaway and spontaneous combustion.

What will be the effect of charging an electric car for too long: once or twice is nothing, because now the battery in the hall slide part will be fully charged, and there is a function of automatic power off after being fully charged. However, after a long time, the parameters of the charger will change slightly due to the relationship between the environment, such as high temperature, low temperature, humidity, dropping, etc., which will cause the battery to bulge, lose water too quickly, and reduce capacity.

In addition, the charger will continue to heat in the state of general wax electricity, which has potential safety hazards. It will accelerate the aging rate of the internal components of the charger, reduce the performance of the charger, reduce the service life, and speed up the scrapping. Remember to unplug the power supply within 1 to 2 hours after full charge to avoid damage to the battery or spontaneous combustion of the battery.

Therefore, the charger must be original, and it is best not to use other fast chargers or chargers of different brand specifications, but to buy them from regular merchant stores. Do not connect the socket to charge the battery by yourself. It can also be equipped with an overcharge protector or a timer socket, which will automatically power off after being fully charged.

1. Try to wait until the battery is used up before charging. Inside the battery is the battery solution. There's water, there's chemicals like electrolytes.

Among them, the role of water is very large, if the water is exhausted, the electric Hu burning pool will be scrapped. If it is charging at any time, it is extremely easy to run out of water, so it is best to run out of power and charge it again when the pants are hail to reduce the number of charges.

2. Every time you charge, it is best to wait for the battery temperature to be normal before charging. Don't charge it immediately after riding every time, the battery temperature is relatively high at this time, and charging it immediately will make the temperature higher and not conducive to the life of the battery.

3. Use a charger that meets the battery specifications.

4. The current and voltage cannot be guessed wrongly.
