Can an electric car be used if it is not fully charged

Member of China Electric Vehicle Alliance:

The correct way to use the consumer battery.

Some consumers use batteries in improper ways, one is to charge for a long time, thinking that the longer the charge, the more power; the second is to lose power for a long time, and it will not be charged until it can't run; the third is to charge when the temperature is too high or too low; Fourth, do not pay attention to the regular inspection and maintenance of the battery.

The correct use method can play a role in prolonging the life of the battery to a certain extent. Now I will give a brief introduction to the correct way to use it:

1. It is not advisable to charge after riding.

The life of a battery is determined by the number of charge-discharge cycles, and the more times it is charged-discharged, the faster the life will be reduced. Therefore, you should not just ride an electric car and then charge it, but should master it when the maximum mileage of the battery is 60%-70%.

2. The charging time should not be too long.

Many EV users believe that the longer the charging time, the more battery power there is. This is very wrong. The charging time is generally extended within one hour after the charger is changed.

Long-term overcharging can easily lead to battery deformation, water loss and other phenomena. Thus directly jeopardizing battery life. (The first three charging times of a new car are:

12-14 hours, after the charging time: 6-8 hours).

Third, it is best to use a smart socket.

Many electric vehicle users go home from work to charge, and cut off the power when they go to work the next day, in fact, most chargers cannot 100% guarantee that the battery will automatically turn off when the battery is full. The best way is to buy a smart socket and set the time when charging, so that you can solve the problem of resting at night.

Fourth, it is strictly forbidden to exercise without electricity.

Some users wait until the electric car is not moving, which seriously harms the battery performance. Multiple deep discharges can drastically reduce battery life. If the power is not sufficient on the way, it is best to pedal the assist in advance to avoid deep discharge.

5. Do not charge when the temperature is too high or too low.

The battery itself will generate a small amount of heat during the charging process, and charging at too high a temperature will increase the temperature of the bottle and damage the performance of the battery. The temperature is too low. The battery has poor receptivity, weakened activity, insufficient battery power, increased number of charge and discharge, and shortened battery life.

You can use it, but it's best not to run out of battery and charge it as you ride.

Can be used.

First of all, most electric vehicle batteries are lead-acid batteries, which have a certain number of charging and discharging, generally around 350 370 times. If the user chooses to unplug it before it is fully charged, it is equivalent to wasting an opportunity to fully charge. For example, if a new battery is charged and discharged 350 times, when the first charge reaches 70, the plug is unplugged, which means that 30 of the current charge is not utilized, and only 349 times of charging and discharging opportunities are left.

Secondly, it is also incorrect to charge once with one charge, whether it is from the number of charging and discharging, or from the aging of the battery, charging once will accelerate the aging of the battery, and the use of this method for a long time will make the capacity smaller.

Finally, if the electric vehicle is not fully charged, it will be charged once, and it will accelerate the speed of battery water loss, and long-term operation will also make the battery charge and affect the battery life. Once the battery is charged, it will be an irreversible situation and basically cannot be repaired, so you can only choose to replace the new battery. Therefore, as a user, we must avoid unplugging the electric car when it is not full, and charging it once it is used.

Riding note: When riding uphill, on bridge, and against strong winds, electricity and manpower should be used at the same time to reduce the load on the battery and motor. How to ride at startup:

Generally, electric bicycles have a zero-start function, that is, when they are stationary, open the electric door, and turn the speed control handle to start driving.

However, the starting current at this time is two to three times that of normal driving, which has a great impact on the motor and battery, especially the battery. So in order to extend the driving range of a single charge and the service life of the battery;

When starting, the foot pedal should be started first, when the foot pedal.

After a certain speed in the third or fourth lap, the circuit is turned on, which is especially important in areas with heavy traffic and many traffic lights. Frequent zero starts will inevitably shorten the life of the battery.

Here I am: yes, why? Because now the electric car battery is only divided into two parts:

Lead batteries and lithium batteries!!

Lead-acid batteries are basically gone, and now they are all lithium batteries! The cost of production is basically the same! The so-called Tianwei and Super Energy first-line brands, the quality is good, but the advertising cost is large. So** not cheap!

Lithium batteries don't actually exist, the so-called must be released before they can be rushed, and they have to be rushed three times before 12 hours! This is a misunderstanding!!

The real way is to put it almost there, and there is about 10-15% of the electricity that can be flushed! Just fill it up! In fact, some people react that the battery is good for the battery every day!!

So don't worry about your problem, it won't hurt the battery!!

Hehe. Hope mine can help you!!

Battery flushing every day is good for the battery!

The real way to do it is to put it almost there! This is a misunderstanding, it won't hurt the battery!! The production cost is basically the same, but the advertising cost is large! Just fill it up! : Yes, the quality is good!! What is the so-called Tianwei!

Hehe. Hope mine can help you!! Why. So** not cheap!

Lead batteries and lithium batteries!!

So don't worry about your problems! In fact, some people react!! , the so-called must be discharged before it can be rushed, there are about 10-15% of the electricity can be rushed, and it must be rushed three times before 12 hours!

Lithium batteries don't actually exist, super energy ah, a first-line brand! , now it's all lithium batteries!

Lead-acid batteries are basically gone? Because the current electric car battery is only divided into two pieces, I'll do it.

It is best not to always discharge more than half of the lead-acid battery, which affects the lifespan, and it is best to keep the lead-acid battery full.

If you don't charge it, you can use it, it must be bad for the battery, and it has no effect once in a while.

It must be fully charged for the first time and reused and must reach the time specified in the instructions.

It is best to charge it again in the future, as it is good for the battery. Beg.

There will be an impact. Once or twice is no problem, but after a long time, the plate is easy to vulcanize and crystallize under the condition that the battery is undercharged for a long time, and it adheres to the surface of the plate to block the reversible reaction between the plate and sulfuric acid.

Capacity decreases. The charging time of ordinary electric vehicles is generally 8-12 hours, do not overcharge, overcharging is easy to lose water - battery hot - water loss - hot battery burst deformation. This process is the battery capacity.

Descending, entering the process of a vicious circle.

Battery maintenance method:

1. Use the charger correctly.

Determine if the AC power supply matches the charger input voltage. Determine the charger output voltage and the battery voltage rating.

Whether it matches. Plug in the plug where the charger is connected to the battery compartment first, and then plug in the AC power plug. The charger is used indoors, and attention should be paid to moisture-proof and shock-proof. It is strictly forbidden to cover it when charging, and it should be placed in a ventilated and heat dissipation place.

2. Prevent the battery from overcharging.

The overcharging of the battery produces a large amount of gas to wash the plates, which accelerates the shedding of the active substances on the plates and shortens the life of the battery. Overcharging the battery accelerates water loss, resulting in electrolyte.

Drying up and the temperature of the battery rises, resulting in thermal runaway, plate expansion, and shell deformation.

There is an impact and can cause damage to the battery. The battery car is fully charged, which will cause the battery plates to vulcanize, and the power storage capacity will be reduced. When driving normally, if the power gauge indicates red and yellow lights, it should be charged; If only the red light is on, it should stop running and charge as soon as possible, otherwise the over-discharge of the battery will seriously shorten its life.

In the case of low temperature, the battery car charging mainly has the problem of poor charging acceptance capacity and insufficient charging to cause battery loss. Thermal insulation and anti-freezing measures should be taken at low temperatures, especially when charging, which should be placed in a warm environment, which is conducive to ensuring sufficient power, preventing irreversible sulfation, and prolonging the service life of the battery.

Extended Materials. Causes of vulcanization of lead-acid batteries.

Long-term retention of the battery, long-term overcharge and undercharge during the charging process, and high-current discharge during use can easily cause vulcanization of the battery. Its appearance is: light as soon as it is released, full as soon as it is charged, we call it the "false damage" of the battery.

The sulfide sulfate adheres to the plates, which reduces the reaction area between the electrolyte and the plates, and causes the battery capacity to decay rapidly. Water loss can aggravate the sulfidation of the battery; Vulcanization will aggravate the water loss of the battery, which is easy to form a vicious circle.

The following matters should be paid attention to when using the constant current charging method:

Because the variant of constant current charging is segmented constant current charging, in order to avoid excessive current in the later stage of charging, the charging current should be adjusted in time. Moreover, the size of the charging current, the charging time, the timing of the conversion current and the selection of the charging termination voltage must be strictly implemented.

The remaining capacity of each charged battery should be close to each other, otherwise the charging current must be selected according to the battery with the smallest remaining capacity of the series battery group, and when the small-capacity battery is sufficient, it should be removed immediately, and then continue to charge the large-capacity battery;

During the charging process, the single-grid voltage of the battery should be detected every 2 3 hours, and if the voltage has been reached, it should be transferred to the second stage of charging in time;

When the electrolyte temperature rises to 40 during charging, the charging current should be halved if it continues to rise.

It should be stopped at 45 and can only be charged after the temperature drops below 40;

The density of the charged battery electrolyte shall meet the specified requirements, and the density difference of the electrolyte between each single cell shall not exceed;

Maintenance-free batteries should not be charged by this method.

1. Once or twice is fine, but after a long time, the plate is easy to sulfide and crystallize under the condition that the battery is undercharged for a long time, and (lead sulfate crystals) adhere to the surface of the plate to block the reversible reaction between the plate and sulfuric acid. Capacity decreases.

2. The battery has a storage time life and a life of charging and discharging times, and the general electric vehicle lead-acid battery is charged and discharged about 600 times, that is to say, if it is undercharged for a long time, the power is insufficient and the mileage is short, the charging and discharging frequency is high, and the battery service life is reduced.

3. The battery itself has internal resistance, and the load voltage is low when the power is insufficient, which increases the internal consumption of the battery and reduces the efficiency.

4. The battery will also be naturally fed when it is stored, so it is necessary to fully charge the battery often when it is not in use, let alone when it is in use.

5. Do not charge the battery until it can't walk, which will also speed up the vulcanization of the battery.

6. The charging time of ordinary electric vehicles is generally 8-12 hours, do not overcharge, (don't believe too much in the charger, it can only be protected under certain conditions), overcharging is easy to lose water - the battery is hot - then water loss - hot battery burst deformation. This process is a process in which the battery capacity decreases and enters a vicious circle.

Electric vehicles are indeed a very convenient means of transportation, cars are too big and too troublesome, and they need to spend a lot of money every year for maintenance, refueling and various maintenance. Bicycles are too strenuous to drive, electric cars are just right, and traffic jams have nothing to do with it. Therefore, after I bought my own car, I still often drive electric cars.

It's because electric cars are convenient and cheap, and a single charge is at most a few dollars.

So the question is, can an electric car be fully charged in a few hours? Someone said on the Internet before that no matter what kind of electricity you charge, it will be charged for 12 hours. Anyway, when it's full, it won't continue to be powered.

Even when I was a child, my parents told us that it would take 12 hours to charge anything, otherwise it would hurt the battery, but in fact this is not the case. After you are full of many things, you should end the replenishment as soon as possible, otherwise it will have some impact on the battery pie.

And the words of electric cars,The general charging time is about 8 hoursAs I just said, electric vehicles can't be charged for too long, and if the charging time is more than 12 hours, it will have an impact on the battery life of the electric vehicle. The best state of the battery is not to recharge it after it is used up every time, but to start charging when it is used up to 20%.

This is the best for the state of the battery, of course, there are a few points that you can also pay attention to the dust oak, if you drive an electric car often with people, then it is best to go back to charge every time you use 50% of the electricity. If you don't usually turn it on, then you can use up 70% of the power and recharge, which is the best for the battery.

But if you're not at home a lot, or if you don't drive an electric car very often, then you can't say you don't care about it. It needs to be turned on from time to time and then charged once a month, which is good for the battery. I had an electric car that didn't work for a year, and I couldn't use it when I went to see it later, and the master who repaired the car said that I could only change the battery.

Therefore, we must pay attention to this charging time, many people's batteries are not used badly, but by people who do not understand electric vehicles.

Influential. Accelerate the aging rate of the internal components of the charger, so that the performance of the charger decreases; overcharge the battery and shorten its service life; exacerbate security risks; Increase power consumption. It is recommended that the owner should unplug the charger in time during the daily charging process, which can not only bury the protective charger, but also prolong the battery life.

The impact of not unplugging the charger after charging an electric vehicle is as follows:

1. Accelerate the aging rate of the internal components of the charger, so that the performance of the charger decreases.

There are a lot of components inside the electric vehicle charger, if you don't pull out the charger for a long time, the charging and smiling appliances will always be in the state of connecting current. At this time, the internal components will gradually heat up and accumulate for a long time, which will accelerate the aging rate of the components, reduce the performance of the charger, and affect its life.

2. Overcharge the battery and shorten its service life.

Nowadays, many chargers have charging protection, but even so, if the charger is not pulled out for a long time after being fully charged, there will be a weak current and continue to charge, which will cause some damage to the battery. Long-term accumulation will overcharge the battery and shorten its lifespan.

3. Exacerbate security risks.

The electric vehicle charger will continue to heat up when it is powered on, and now that the temperature is rising, if the electric vehicle is charged in a closed environment, it is very likely to burn the charger and even the electric vehicle, thus causing new safety risks.

4. Increase power consumption.

Although the power required to fully charge an electric vehicle is not much, it is quite a lot of power lost in a year if the charger is not unplugged for a long time.
