The battery of an electric vehicle is generally how many amperes

The majority of electric vehicle 48V batteries are 22 Ah or 20 Ah hours. If it is 12 amps, it is usually about 50 km.

If it is 10 amps, it is usually about 45 km.

Of course, it's big to see, it's good, it's a lot of running!

The battery capacity of electric vehicles is generally: 2200mA h, 5ah, 10ah, and some electric vehicles can reach 20ah or 50ah. The more batteries are connected in parallel, the greater the capacity.

Electric vehicle battery is the power of electric vehicles**, the vast majority of electric vehicles are equipped with lead-acid batteries, lead-acid batteries have low cost, high cost performance, can be charged, and can be used repeatedly.

Extended Materials. Precautions for use.

1. Do not store it at a loss of electricity

The battery is not charged in time after use, resulting in insufficient charging and a decrease in battery capacity. The longer the idle time, the more serious the damage to the battery. When the battery is not in use, it should be charged once a month to prolong the service life of the battery.

2. Master the charging time.

In general, the battery is charged at night, and the average charging time is about 8 hours. The battery is best charged once when the discharge depth is 60%-70% (down to two grids), and it can be converted into riding mileage when it is actually used, and the necessary charging is carried out according to the actual situation to avoid harmful charging.

3. Prevent high temperature exposure.

The environment with too high temperature will increase the internal pressure of the battery and force the battery pressure limiting valve to open automatically, increasing the water loss of the battery, and excessive water loss of the battery will inevitably cause the battery activity to decline, accelerate the softening of the plate, and cause fatal injuries such as shell heating, shell bulging and deformation during charging.

4. In winter, the battery should be heated indoors for two hours and then charged.

The mainstream electric vehicle batteries on the market are generally 48V20Ah, 60V20Ah, and 72V20Ah, and 48V20Ah electric vehicles will be equipped with 500W motors.

There is a label on the battery shell of the electric vehicle, which says how many volts and how many amperes it is, and if you can't see the label, you can use a multimeter to measure. How far the battery car can run is determined by the capacity of the battery car, the larger the capacity, the farther the distance, the smaller the capacity, the closer the distance.

Battery life of an electric vehicle.

The battery of a new electric bicycle is replaced once a year every 1 year, and the general service life of an electric bicycle is 3-5 years. Electric vehicles are generally used lead-acid batteries, which have the advantages of low cost and can be used, and are used by most electric vehicle manufacturers.

Generally, the battery used in electric vehicles is guaranteed for one year, so the battery of electric vehicles is 70% of the battery capacity used every day, and the cycle is one year.

The 5 batteries of electric vehicles are 60 volts, and the most common batteries used in electric vehicles are 48 volts and 60 volts lead-acid batteries, which are composed of different numbers of 12 volt batteries. Electric vehicle battery is the power of electric vehicles, the vast majority of electric vehicles are equipped with lead-acid batteries, lead-acid batteries are low cost and cost-effective. Because this battery can be recharged and can be used repeatedly, it is called a "lead-acid battery".

In years of practice, electric bicycle manufacturers and battery manufacturers have gradually realized the importance of matching between the battery and the electric drive system related equipment, especially the matching with the charger. Manufacturing quality is the premise of battery quality, but only when it is used with the matching charger can the superior performance of high-quality batteries be exerted, otherwise high-quality batteries can not fully exert their potential superior performance.

Use the charger properly1. Determine whether the input voltage of the AC power supply and the charger is consistent.

2. Determine whether the output voltage of the charger is consistent with the rated voltage of the battery.

3. Plug in the plug connected to the charger and battery box first, and then plug in the AC power plug.

4. The charger is used indoors, and attention should be paid to moisture-proof and vibration-proof. It is strictly forbidden to cover it when charging, and it should be placed in a ventilated and heat dissipation place.

Let's talk about the classification of battery models first, the general electric vehicle battery is: 24V, 36V, 48V, 60V, 64V, of which 36V and 48V are the most common.

36V is commonly used: 36V10Ah, 36V12Ah, and some are also used 36V14Ah, 36V17Ah, 36V20Ah.

48V commonly used are: 48V10AH, 48V12AH, 48V14AH, 48V17AH, 48V20AH.

So how do you know the size and model of your electric car battery? Generally speaking, there are two methods. It is to look at the output current of the charger, and you can know what type of battery it is according to the following parameters:

Hint, look at the charger on: output voltage **v dc**a

36V is: output voltage 36V--42V DC**A.

If yes, then it's 10ah.

If yes, then it's 12ah.

48V is: output voltage 48V--59V DC**A.

If yes, it's 48v10ah.

If yes, it's 48v12ah.

If yes, it's 48v14ah.

If yes, it's 48v17ah.

If yes, it's 48v20ah.

The first method sometimes does not work, because some of the poor chargers do not indicate these parameters at all, so I have to use the second method to see, this method is the simplest, most direct and most practical, that is: open the battery box, count how many batteries there are, if it is three, then generally speaking, it is 36V.

The voltage is determined, and then the capacity is determined. If the battery says 6-dzm-10 on it, then it is 10ah, if it is 6-dzm-12, then it is 12ah, and so on.

Of course, there are also some small manufacturers that have the phenomenon of false standard of electric vehicle battery size, for example: 6-DZM-14, he is actually the national standard 10-12ah, 6-DZM-20, he is actually the national standard 17ah, so it is recommended that you choose a regular battery manufacturer when buying a battery.

Of course, there are also some small manufacturers that have the phenomenon of false standard of electric vehicle battery size, for example: 6-DZM-14, he is actually the national standard 10-12ah, 6-DZM-20, he is actually the national standard 17ah, so it is recommended that you choose a regular battery manufacturer when buying a battery.

When the voltage is constant, the larger the a, the farther it runs, but the larger and heavier the battery.

The general electric bicycle is 12A48V

The electric motorcycle is 20a60v

The tricycle is 32A48V

The size and weight of 20 are moderate, and the power mileage is also okay. Therefore, it is more commonly used. Some large electric vehicles, that is, those who take away errands, ride batteries that are generally 72V55A, or even larger, and it is not a problem to run hundreds of miles a day.

The national standard electric bicycle is generally equipped with a 48V12Ah battery, and the motor power is within 400W. Electric mopeds are generally equipped with 48V20Ah, 60V20Ah, and the motor power is generally 400-800W, while the batteries configured by electric motorcycles are generally high-voltage and high-capacity batteries, such as 72V38Ah, 96V32Ah, etc. The following picture is a standard comparison, you can refer to it!

The most common two, one is 12ah, the other is 20ah, and the others are not so commonly used, but there are still a lot of specifications.

The battery of the electric car, each piece is 12V, 48V is four in series, 60V is five in series, and 72V is six, 20A or 24A is the battery capacity, so let's say, if you ride non-stop, 20A 30 km, 24A can run 45 km, the larger the capacity, the farther you run, you say that you want to change the 60V to 48V, because if the controller is 48V, the motor is also 48V The battery should also be 48V, you are now 60V for 48V, I've said so much, do you still change it?

Electric vehicle batteries.

There are three kinds of voltage: 36 volts, 48 volts and 60 volts, which refer to the voltage of the battery, and the current of 12 amps and 20 amps refers to the capacity of the battery, 12ah, 20ah, (for example: 12ah means to discharge at a current of 12a, the battery can be discharged for one hour, and the battery capacity is the product of current and time).

48, 60 and current and other unequal voltages are designed with the power of the tram, generally try not to change, because the design of the battery is to match the controller and motor.

It is best to match the battery according to the factory standard, because your electric vehicle motor and controller are all matched. If you change a smaller battery than the original and can't bring up the motor, not to mention, it is still a waste battery, for example: it is a calf pulling a big car.

Generally, the battery is replaced by the whole group, so it is good for the car, and the battery of the electric car is best Tianneng, Panasonic, Chaowei, and the others should not be replaced. It's cheap, but it doesn't take long. A small battery is 12V, like your car needs to use 5 12V batteries to match 60V, not that a battery is V, this is not, the batteries are connected in series with 12V.

In addition, the 12 amp and 20 amp batteries are not the same size, so the position of your battery box is limited, and you can't fit it if it's big.

V stands for voltage and A is for capacity.

For example, a battery is equal to a cup, a cup, it can hold 12 ml of water, it can also hold 20 ml of water, the bigger the amp means the larger its capacity and run farther

This is related to the rated voltage of the motor of the electric vehicle, replacing the battery with a smaller voltage than the original may not move the motor, and replacing it with a voltage larger than before may burn the motor.

Then what electric car do you have to look at, the more expensive the configuration is higher. The voltage and current of a cheap battery are lower. Volts and amperes are the units of voltage and current, respectively, haven't you learned this before?

Common voltage: 12V

36v48v

The battery of 60v Emma is 48v, which is the main indicator, and the voltage cannot be low.

Ampere-hour, ampere-hour, a unit that measures the capacity of an energy storage device.

It can be simply understood as: 1a

h indicates that the energy storage device can continue to work for 1 hour when the power supply current intensity is 1A.

The standard voltage of each battery of an electric vehicle is 12 volts, and the four batteries in series are 48 volts. There are many models you are talking about, in fact, there are many kinds of battery capacity, the common ones are 12A H, 15A H, 20A H (A H - Amperes, the larger the number in front, the larger the capacity of the battery), etc., the capacity is different, but the voltage is always 12 volts per section. Secondly, the model number is the number of each manufacturer.

At present, there are two types of batteries used in electric vehicles. One is a lead-acid battery, and the other is a lithium battery, and the lead-acid battery is printed on the wall of each battery with a battery capacity mark. For example, 20Ah means that the battery is a 20 amp battery.

If the lithium battery is produced by a regulated manufacturer, the battery voltage and current are also printed on the outer packaging.

It is not a few amperes but how many ampere-hours that is, ah, which is the capacity of the battery rather than the current value, which is generally marked on the battery label.

The batteries are all marked.!

You can find the manual on the regular battery car, and the output voltage of the battery car is indicated on the manual, that is, how many volts, and after opening the battery cover, you can check how many amperes the battery capacity used by the battery car.

The battery voltage and capacity used in the battery car are expressed by V and A, V stands for volt, which refers to the total voltage of the battery car, A refers to the ampere, which refers to the capacity of the battery car, and usually, the mileage that the battery car can drive is determined by the battery capacity used in the battery car.

The larger the battery capacity used in the battery car, the longer the driving range will be, and the smaller the battery capacity used, the closer the driving range will be.

In addition, the power of the battery car is determined by the voltage, that is, the greater the total voltage of the battery, the stronger the power of the battery car, and the smaller the total voltage of the battery, the smaller the power of the battery car.

The battery voltage and battery capacity used by different brands and different types of battery cars are different, mainly according to the specific use of the battery car.

In addition, the power of the electric vehicle is not determined by the battery alone, but also depends on the controller and the motor, and these comprehensive factors need to be considered to determine the power of the electric vehicle.

Summary. The battery of an electric vehicle is generally around 20 amps. There are some three-wheeled electric vehicles, and there are also 60 amp batteries.

1.The battery of a two-wheeled electric car gives you a maximum of 20 amps. Because the higher the value of the current, the more expensive the battery.

2.The higher the current of the battery. The longer the range. The faster the speed. Because it can meet the instantaneous high current required by the motor. So the speed is fast.

3.If you want a long range. If the voltage is certain, choose a battery with a large current.
