How to look at the battery of an electric car, how to see how many batteries an electric car has

Generally, each electric vehicle battery is 12V, but also 6V (rarely used); The battery shell is generally printed with 6-dzm- (number), the number represents the battery capacity, such as: 12, that is, the battery is 12ah (ampere-hour); Generally, there are 10ah, 12ah, 14ah for small electric vehicles, 16ah, 17ah, 18ah, 20ah for large electric vehicles, etc., the capacity of the battery represents the size of the mileage that can be run, and the mileage of the large capacity is larger, and the larger one can be selected, ** The difference is not big; It can be connected in series to form 36V, 48V, 60V, etc., the general safety voltage is 36V, but with the current situation of overspeeding of people and goods, the voltage is getting bigger and bigger, and you can choose according to your actual situation.

1。If you want to see if there is damage, you can use 30% of the power to go to the sales office and use the device to check the discharge level.

2。If you want to see the quality of the new battery, you must first choose a good brand, and then look at the appearance of the battery, if there are scratches and dirt, it may be to maintain the battery (that is, 80% of the qualified products in the manufacturer's factory) or refurbished batteries, the most important thing is to use it fully charged.

3。The voltage doesn't need to be seen, it's all 12V. The capacity can be seen by the volume, now there are 2 kinds of general, the small one is 3mah and the large one represents milliampere h refers to hours For example, a 900mah battery means that the battery can work for one hour in the case of power consumption of 900 mAh!

The power consumption depends on the controller range.

Hope it helps.

Open the battery box can be seen, generally have brand and power, the current two-wheeled electric vehicle is generally placed 4 pieces, each piece 12V, 4 pieces is 48 volts, the battery shell is generally printed with 6-DZM- (number), the number represents the battery capacity, such as 12, that is, the battery is 12 ampere-hour (AH), as mentioned above, this group of batteries is 48V12Ah.

There are two kinds of batteries for electric vehicles: generally 4-6 batteries, each battery is centimeters long, centimeters wide, and centimeters high. , a rectangle, a square.

According to the size of the battery, the battery compartment of the 60V electric vehicle should be about 30 cm, and it should also be calculated according to a few 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".

Mastering the best EV battery charging method after buying a new EV will go a long way to improve the life of the EV battery

1. Under normal circumstances, electric vehicles (not often with people, not climbing all day), generally drive to 60%-70% of the longest continuous mileage on the manual before charging is the best, which can not only avoid the early capacity loss of the battery, but also avoid over-discharge.

2. If you often take people and climb slopes, it is recommended to drive to 50% of the longest continuous mileage on the manual to charge.

3. If you usually drive very little, and you don't drive to 60%-70% of the longest continuing mileage in a week, it is recommended to charge it once.

4. In any case, the battery charging time should not exceed 8 hours, especially in the case mentioned in point, not more than 5 hours.

There are several ways to inquire about the battery car battery:

1. Check the nameplate on the battery, there will be corresponding nameplates and stickers on the battery of electric vehicles, and there is a basic introduction to the model and parameters of the battery, such as "12V60Ah" means that the rated voltage of the battery is 12 volts;

2. Multimeter measurement, dial the gear of the multimeter to the DC voltage measurement gear, then use the red pen to measure the positive pole, the black pen to measure the negative pole, and see the value of the multimeter pointer or liquid crystal display is the voltage of the battery;

3. Go to the electric vehicle manufacturer's ** to inquire about the battery specifications of the corresponding model, or ** contact the manufacturer to inquire about the nominal voltage of the battery.

Electric vehicle batteries are generally 12V for a group, 48V for 4 groups, 60V for 5 groups, the original charger has a charging voltage index for reference.

Look at the EV charger, look at the rear-wheel motor.

You need to open the battery box to see that the capacity of the battery is written on the battery, and the electric vehicle battery is marked on it: such as 6--dzm--126---dzm--20 is the voltage in front of the number behind the capacity is read: 12 volts 12 volts 12 volts 20 amps.

6-dzm-14.It means that this battery is 14ah, and 6-dzm-10 is 10ah. 6-dzm represents lead-acid type batteries, and the following numbers represent capacity. And 17ahTarget.

There are two ways to look at the EV battery model:

One is the output current of the charger. Look at the output voltage **VDC**A on the charger, 36V is: output voltage 36V--42VDC**A; If yes, then it's 10ah; If yes, then it's 12ah; 48V for:

The output voltage is 48V--59VDC**A.

The second is to open the battery box and count how many batteries there are, if it is three, then it is generally 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.

Electric vehicle battery model classification, general electric vehicle battery is: 24V, 36V, 48V, 60V, 64V these four, of which 36V and 48V are the most common.

36V is commonly used: 36V10Ah, 36V12Ah, and some are also used 36V14Ah, 36V17Ah, 36V20Ah. 48V is commonly used as:

48v10ah，48v12ah，48v14ah，48v17ah，48v20ah。

The models mentioned by the global electric vehicle network evaluation group refer to lead-acid batteries, and the general electric vehicle battery specifications are divided into three 6V, 48V, 60V, and 64V.

With the upgrade of simple electric bicycles, the 36V that was often used in the past has gradually faded out of people's sight, and the current 48V is the most common, accounting for more than 90% of all electric vehicle users.

The charge of an electric vehicle is displayed by the fuel gauge. After opening, the pointer points to H, indicating that the battery is full, with riding, the pointer gradually moves slowly in the direction of L, indicating that the power is gradually decreasing, and the pointer will be charged in time when it reaches a quarter of the deviation L. When starting, add hand oil hard, the oil gauge will fall to L, if the table immediately returns to H, it means that the battery still has a lot of electricity, if the meter does not rise to H, it means that there is no electricity.

1. The first method is relatively simple, that 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.

2. Wang Tuan's method is the simplest, simplest, most direct and most practical, that is: open the battery box and count how many batteries there are, if it is three, then it is generally 36V.

Electric vehicle maintenance method barrage:

1. Use the charger correctly.

Determine if the AC power supply matches the charger input voltage. Determine whether the output voltage of the charger matches the rated voltage of the battery. 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.

Second, the battery cannot be charged at any time.

1. The lead-acid battery is not a lithium battery, it can not be charged at any time, the life of the lead-acid battery is calculated according to the number of flushing and discharging, the battery is most afraid of power loss, and often keeping enough power can extend the life of the battery.

2. When charging, the indicator light of the charger is red first and then green, and the floating charge should be guaranteed for 2 hours after the light turns green, which is good for inhibiting battery vulcanization.

3. Prevent the battery from overcharging.

1. The overcharging of the battery produces a large amount of gas to wash the plate, which accelerates the shedding of the active material on the plate and shortens the life of the battery.

2. The overcharging of the battery accelerates water loss, resulting in the drying up of the electrolyte and the increase of the battery temperature, resulting in thermal runaway, plate expansion and shell deformation.

Fourth, prevent the battery from over-discharge.

Prevent high-current discharge, and try to assist with your feet when starting, uphill, and upwind.

2.Prevent long-term discharge, and do not drive after discharging frequently. Charge when the charge level is reduced by 1 2.

5. Prevent battery power loss.

For batteries that have been left unused for a long time, they should be fully charged once a month, and it is generally better to continue to float for 5 hours after the charger turns red to green.

6. Take care of the battery frequently.

Although the electric vehicle battery is maintenance-free, after half a year of use, with the continuous consumption of water, the vulcanization and softening of the plates will occur, which will cause the battery capacity to decrease or even fail. Choosing to supplement with nano-carbosol battery activator and an appropriate amount of distilled water can extend the battery life to two years.

Open the battery compartment and count how many batteries there are, if it is three, then it is generally 36v.

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

Of course, there are also some small manufacturers that have the phenomenon of false standards for the size of electric vehicle batteries, such as: 6-DZF-14, he is actually the national standard 10-12ah, 6-DZF-20, he is actually the national standard 17ah. Therefore, it is recommended that when you buy a battery, you should choose a regular battery manufacturer.

You can check the smart meter on the battery car, it's clear.

1. The power of the electric vehicle is displayed by the fuel gauge.

2. After opening, the pointer points to H, indicating that the battery is full.

3. As you ride, the pointer gradually moves slowly in the direction of L, indicating that the power is gradually decreasing.

4. When the pointer reaches a quarter of the deviation L, it should be charged in time.
