I want to swap out my EV battery, is there anything I need to pay attention to? Voltage, current, ch

Impactful. For example, if your charger is 48 volts 12 ampere, and the battery you change is 48 volts 20 ampere, the battery will always be uncharged, and the electric car will run out of power after a long ride. On the contrary, the battery will damage too quickly, or even burst the battery.

It is recommended to bring the charger when returning the battery, ask the merchant who bought the battery, and let him test what model the charger is for you.

The voltage, current, and dimensions should be the same as the original. In this way, the installation is easy and the rated power is guaranteed.

Replace the battery, the voltage and current are different from the original, no. It's too small to drive an electric car.

The voltage is the same, the current is larger than the original, (the ampere-hours are larger than the original, but the volume is larger than the original,) is OK. But it is better to replace the corresponding charger at the same time.

Hello! It is recommended to replace the battery in its original configuration. The rated voltage of the battery is greater than that of the motor and other accessories, which may burn out these parts, and if it is smaller than the motor, it will be difficult to drive the motor to operate. It is recommended to change the configuration to the same one.

Electric car battery, nothing to pay attention to, choose a good brand, such as Tianneng, Chaowei, and your electric car original volt is the same!

There is a phenomenon of virtual soldering in the output circuit of the charger, which causes the voltage to be measured at the output terminal, and there is no current or only a small current output after the load is added. If you can understand this sentence, it is not difficult to fix, but if you can't understand it, you need to ask someone to help.

The voltage cannot be changed, and the capacity can be increased.

Go to a regular store to replace the battery; Pay attention to the date on the battery when changing the battery; Check whether the electric vehicle battery product logo is complete; It is best to change the brand battery, after the new battery is installed, it is best to use up the electricity in the charging, three times in a row, so that the battery can be activated, do not use up the battery before charging, must leave 10% of the electricity, so as to increase the service life of the battery.

In the process of use, if the driving range of the electric bicycle suddenly drops by more than ten kilometers in a short period of time, it is very likely that at least one battery in the battery group has a short circuit phenomenon such as broken grid, plate softening, and plate active material falling off. At this time, you should go to a professional battery repair institution for inspection, repair or matching.

Precautions for battery maintenance of electric vehicles.

If the battery car is not used for a long time, it also needs to be charged regularly, don't think that it is okay if you don't use it, the battery will be seriously reduced if it is not charged regularly, and the service life will be serious and even scrapped.

When riding an electric car without power, you must not continue to ride, although you can continue to drive for a certain distance, but the damage to the battery is huge. Reduce the service life of the battery, we often forget the charging time when charging, resulting in the full charge and then continue to charge, so that overshoot will lead to water loss of the battery, affecting the service life.

1. When replacing the battery, be sure to consult about safety, and the main thing is how to use it. How long the shelf life, the method of initial charging, including the issuance of an invoice as evidence, these are the details that basically guarantee their rights.

2. Try to replace the original manufacturer. You can go to the merchant who bought the electric car or the store of the same brand to replace it, so as to ensure the original brand, quality assurance and safety assurance. However, it will be a little higher in terms of **.

Category 1, partially updated.

When replacing the battery of electric vehicles, the new battery must be completely consistent with the original battery category, specification and model, in addition to voltage, capacity, power, and charging system must be consistent with the original battery, and the original battery pack should be in the early stage of life, at least not in the later stage of battery life.

The whole group of batteries is in the late stage of life, and it is no longer meaningful to replace individual single batteries, and it is best to replace them all after the end of the life of the whole group of batteries. Regardless of whether the battery of an electric vehicle is replaced as a whole or individually, it should be matched with the original charger and controller.

2. Replace the whole group.

If the entire group of batteries is replaced and the battery category is changed, the characteristics of the controller and charger are involved, which must be consistent with the characteristics of the battery, such as charging rate, charging end, discharge and other requirements.

Hello friends? Pay attention to the replacement of the battery of the electric vehicle, 1;Go to the regular store to replace the battery, 2;Many of the batteries in the refined electric car shops on the street are refurbished batteries, you look new, in fact, they are refurbished, accidentally deceived, now there are some professional refurbished battery workshops, refurbished to electric car repair shops. I was fooled once, scolded them for a month, maybe some electric car repair shops are good batteries, can not be generalized.

3；After the new battery is installed, it is best to use up the electricity before charging, three times in a row, so that the battery can be activated, and do not use up the battery in the future to remember to charge, and must leave 10% of the electricity, which can increase the service life of the battery. 3；Do not charge under the sun in summer, and do not charge when it is freezing, 4Do not charge immediately when you ride home for a long time, wait for ten minutes to start charging to increase the service life of the battery.

Share the marks that must be paid attention to when changing the battery of an electric vehicle.

It is best to change the brand-name batteries such as Chaowei and Tianneng, and the general dealer has a one-year warranty for the customer, so be sure to let the dealer fill in the warranty policy.

The brand should be famous (about 30 yuan expensive), the current should be large (15A for small batteries, 24A for large batteries), and the warranty period (15 months for small batteries and 12 months for large batteries), you must ask for a warranty.

The battery car is replaced with a new battery, and the first charge is not to use up the electricity and recharge.

The battery car power is generally retained by 20%, and if it is less than 20%, there is a risk of power loss, and the battery life is shortened by 80%.

Electric vehicle batteriesIt is the power of the electric car**, and the vast majority of the electric vehicles are installedLead-acid batteriesLead-acid batteries are low cost and cost-effective, because this battery can be recharged and can be used repeatedly.

A battery is a type of battery, also known as a storage battery, which works by converting chemical energy into electrical energy. Usually the battery refers to the lead-acid battery, that is, a kind of electrode mainly made of lead and its oxide, and sulfuric acid solution as the electrolyte.

of batteries. 1. Ordinary battery: The plates of ordinary batteries are composed of lead and lead oxides, and the electrolyte is an aqueous solution of sulfuric acid.

Its main advantages are stable voltage and low price; The disadvantages are low specific energy (i.e. the amount of electrical energy stored per kilogram of battery), short service life, and frequent routine maintenance.

2. Dry-charged battery: the full name is dry-charged lead-acid battery, its main feature is that the negative plate has a high power storage capacity, in a completely dry state, it can save the power obtained within two years, when used, only need to add electrolyte, and wait for 20-30 minutes to use.

3. Maintenance-free battery: Due to the advantages of its own structure, the consumption of electrolyte is very small, and there is basically no need to replenish distilled water during the service life.

It also has the characteristics of shock resistance, high temperature resistance, small size, and small self-discharge.

The service life is generally twice that of ordinary batteries. There are also two types of maintenance-free batteries on the market: the first one is to add electrolyte at one time when purchased, and no maintenance is required in later use (add replenishment solution); The other is that the battery itself has been added with electrolyte and sealed at the factory, and the user cannot add refill liquid at all.

1. Should the battery be discharged before charging?

Unlike other secondary batteries, lead-acid batteries have no memory effect, so no matter what state of charge the battery is, it can be charged directly without discharging.

2. Do I need to charge a new battery before using it?

The battery is generally in a fully charged state when it leaves the factory, but there will be a phenomenon of self-discharge in the sales process, so the new car should be replenished before use. Simply charge the new car with the special charger until the green light is on.

3. Does it take 24 hours to fully charge for the first time?

Generally, the battery of an electric vehicle is fully charged in 8 to 10 hours, and the battery can be appropriately floated for another 1-2 hours after it is fully charged, but remember that it is best to charge it for no more than 12 hours each time. Otherwise, the battery will bulge and deform due to overcharging. In addition, after the battery is used for more than half a year, the battery should be deeply discharged once a month, and then charged the battery after deep discharge, and the time should be controlled at about 12 hours, which will help the recovery of the battery power of the electric vehicle.

4. How much power is left before charging?

Whether it is a newly purchased electric vehicle or an electric vehicle that has been used for a period of time, the battery cannot be completely used up and recharged, which will cause the battery to lose power and seriously reduce the battery life. The specific charging should be based on the actual situation, under normal circumstances, it is best to start charging when the power is about 30% left.

5. For the first charge, the safety issue should be kept in mind.

It's best to charge your new electric car during the day, so you can better control the time. When charging, it is best not to place the charger next to objects that are prone to heat and burn, and it is best not to put it on the seat of the battery car to prevent overheating**.

All in all, the maintenance and maintenance of electric vehicle batteries is very important, the correctness of the charging method directly affects the service life of the battery, and even the improper charging method will have potential safety hazards such as **, I hope the majority of car owners pay more attention to it!

As a veteran lead-acid battery production group, Changxin Battery has excellent reputation and quality, and has been praised by the market for many years. As a high-end product in lead-acid batteries, Changxin graphene series adopts a more scientific direct connection structure, an upgraded formula with higher energy density, and a higher technology content, bringing longer life, longer endurance and more stable performance.

Hello, the new battery needs to be charged. When the new battery is charged for the first time, it must take a long time to ensure that it will be fully charged. Once a new battery is in service, it must be charged and discharged regularly.

The purpose of charging is to enable the battery to store electrical energy and restore its capacity in time to meet the needs of electrical equipment. The purpose of discharge is to check the capacity parameters of the battery in time and promote the activation reaction of the active material of the electrode.

For lead-acid batteries, no matter how far or near they are, they should be charged immediately after use, and they should be charged as they are discharged, and they should not be charged until the power is completely exhausted. If the car is not used for a long time, it is also necessary to ensure that the battery is replenished once a month. This protects the battery and extends its lifespan.

If the electric car is replaced with a new battery, it does not need to be charged, because the new battery has about 80% of the electricity, and it will be good for the battery when he is about to run out. He is the same as our mobile phone, the battery is charged after buying, and he must be charged when he is almost gone.

The electric car needs to be charged for a new battery, just after changing the battery car, the new battery needs to be charged, which is full of some batteries, and cannot run for a long time, it needs to be fully charged for ten hours.

Riding home must be charged, the battery needs to be maintained, and the unused battery must also be charged once a month, so that the battery will not be harmed.

It can be charged or used without charging, as new batteries are generally pre-charged. Unless the battery time is long, there are many leaks, and if you are about to travel long distances, it is best to fully charge it first.

Whether to charge the battery (not just an electric vehicle) depends on whether there is enough electricity to see if there is enough. If there is enough electricity, there is no need to recharge.

Generally, the new battery is replaced without charging, when the battery is full, if you change the new battery is out of power, then it can basically mean that the new battery has been put for a long time or there are other reasons.

The new batteries of electric vehicles are charged and shipped out, but the batteries have the characteristics of self-discharge, if it is a new battery, because the factory time of the battery is different, then charging is only good and no harm. ，

It depends on what kind of battery, if it is a lead-acid battery, it is necessary to run out of electricity and then charge it. If it is a lithium battery, it can be charged at any time.

Hello, 1. Confirm the battery installation part, most models are installed in the engine compartment or luggage compartment, and some models are installed in the cockpit, remove the external protection devices such as the battery protective cover, and measure the voltage between the poles with a multimeter.

2. If the vehicle is equipped with an anti-theft system, you can connect the external power supply first, or connect a battery with sufficient power in parallel. Note that the positive pole of the external power supply can be directly connected to the positive pole binding post, but the negative pole should not be directly connected to the negative terminal post, but should be connected to the body tie iron.

3. Turn off the ignition switch of the faulty vehicle, first disconnect the negative connection line, and then disconnect the positive connection line. If it has a snorkel, remove it first.

4. Dismantle the fixing device of the battery and take out the battery. If the vehicle is connected to an external power supply, be careful not to make the positive wiring come into contact with the body, and use a cotton cloth to isolate it. If the old battery is leaking and corroding, it is also necessary to clean the connecting wires.

This one is the same, it has a special place to put the battery. Remove it and reinstall it, the interface of the same model is the same.

Hello! Friend replacement method and steps: 1:

When the battery arrives, remove the shell of the battery with a screwdriver. 2: Take out the battery pack in the battery, pay attention to the positive and negative poles of the wiring when taking it out, reduce the wire of the battery pack with scissors, replace it with a new battery, connect the positive and negative poles according to the original wiring order, and solder with an electric soldering iron.

3: Put the welded battery pack back into the battery case, just screw the screws, the new battery is generally full, no need to charge, use up the battery, charge for about 10 hours for the first time, and the charging time should not be too long in the future. 4:

At this point, the normal battery replacement is completed, as long as you are careful, it is very simple, let's talk about special circumstances, if you have a multimeter in your hand, you can use a multimeter to test the voltage at both ends of each battery pack, if it is not about 12V, it means that there is a problem with the battery, usually there are one or two problems, we only need to replace these two bad ones, you can save a lot of money. Hope it helps.

I hope you can give me a thumbs up, your thumbs up are important to me, thank you.
