Does it affect the use of electric vehicle batteries before they are fully charged?

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.

Unplugging the electric vehicle when it is not fully charged will not harm the battery, but it is recommended to unplug it after it is fully charged, so as to make more reasonable use of the battery. Because most of the batteries of current electric vehicles have a memory effect, it is necessary to charge them reasonably. Electric vehicles are divided into AC electric vehicles and DC electric vehicles.

If the electric vehicle is not fully charged, it will be charged once, and it will speed up the speed of battery water loss, and long-term operation will also make the battery inflated, affecting 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 battery with a new one. Therefore, as a user, we must avoid unplugging the electric car when it is not full, and charging it once it is used.

Precautions for electric vehicle batteries.

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.

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.

Not being fully charged once has no effect on the battery, not many times, many times will have an effect. The electric car you just bought should be charged first, the new battery should be charged for 10-12 hours for three consecutive days, usually charged with use, the power consumption of each ride is best not to exceed two-thirds, and it must be fully charged before each ride to ride, only in this way can the life of the battery be extended.

Battery memory effect refers to the phenomenon that if the battery is a nickel-cadmium battery, it is easy to leave traces in the battery and reduce the battery capacity if it is not fully charged and discharged for a long time.

The battery memory effect means that the battery seems to remember the user's daily charging and discharging amplitude and mode, and it is difficult to change this mode over time, and it can no longer be charged or discharged by a large amount. Lithium-ion batteries do not have this effect.

Summary. This situation must have an impact, the power itself is not full, or often, so that the normal performance of the battery itself can not be maintained, which will have a great impact on the service life of the battery.

Electric vehicles are often charged, but they are not fully charged, is there any harm to the battery?

This situation must have an impact, the power itself is not full, or often, so that the normal performance of the battery itself can not be maintained, which will have a great impact on the service life of the battery.

Therefore, the normal suggestion is that it is best to charge the battery here after each use, and when it is not in use, fully charge the battery to keep the battery in the best condition.

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.

Occasionally, once or twice has little effect, but often, it has a great impact on the service life of the EV battery.

The specific impact is reflected in the following two points:

1. Accelerate the use of electric vehicle battery cycles.

At present, the main battery is mainly lead-acid battery, taking Tianneng battery as an example, generally speaking, the number of complete charge and discharge is about 360 times, theoretically not charged once, it is a cycle, if it is not fully charged, unplug the charger, it will consume the number of charge and discharge times prematurely, so that its life declines.

2. Speed up the water loss rate of electric vehicle batteries.

When an electric vehicle is charging, it releases a lot of heat, and the internal temperature of the battery also rises. If you unplug the charger before it is fully charged and ride directly, the temperature of the originally high battery will become even higher. At this time, the battery loses water faster, which accelerates the aging rate of the battery.

If the battery is charged at more than 80%, it is also called not full, as long as it is not discharged for a long time, it will not have much impact on the battery.

If the battery is not fully charged, and the battery is put into a state of power loss, this is fatal damage to the battery.

The battery has no memory effect, there is nothing special about charging, it cannot be over-discharged (not less than 20% of the power can be charged at any time), and yes, it is best to charge it after use, so that the lead sulfate is deposited on the plate as little as possible, and it cannot be overcharged, and the charging display can be full, and it doesn't matter if it is not full.
