How long can a 48v lithium battery operate?

450W Dayang electric car, with the car with the super-wet lead acid used for two years is not a force, the top can run 20 kilometers, this year pushed a few cars, these days a few times is only about 10 kilometers, the intention this winter sets lithium batteries, AMD recently read a new lithium battery very cheap, Taobao into a

The battery comes with about 56V, the voltage of the lamp is 58.9V, 58.2V when it is fully charged, 57.9V after 24 hours, and 57.9V after 24 hours.

Installed on the car door, twisted, too special cool, start very good, low speed and lead acid mid-range almost, mid-range is faster than lead acid, and no longer use lead acid, then the problem comes, 48V12A lead acid recovery How much is it?

Start slowly and turn around, the violent starting voltage is directly reduced from 58V to 52V. After the starting speed is stable, the low voltage is about 55V, and the mid-range is about 54V. Then the problem is coming again. Is this voltage drop normal?

Add: No mileage calculation. The day before yesterday, the violence ran for less than 15 kilometers, the driving voltage was about 48V, and the parking voltage was 52V. The total mileage felt not very optimistic.

It is undeniable that the car is not far from the configuration of the car. The 48V battery is normally enough for 35KG to run.

Besides, many of Emma's cars are all brand-name cars and then hang up a sheep's head. If the car you bought at that time is directed at the price, these problems are also in the middle of the situation, my friend has eaten this loss.

The 48V battery is divided into 4 sections of 12V. If each voltage or current is too different, it will affect the performance of the car. Although it is a national famous brand, it is impossible for each battery to be good.

I suggest you change the battery to another car to try, it is better to be new, compare it and see.

The mileage of an electric car is mainly related to the capacity of the battery.

However, the battery's charge and discharge capacity, charger charging status, motor efficiency, road conditions, and rider's condition will affect him.

Now suppose that all the conditions are normal, only considering the capacity of the battery, how much is the battery running mileage of 48V12AH? Just assume that your electric car is the mainstream configuration of the 350W motor.

The working current of the 350W motor is generally 6-7A, then the discharge time of the battery is 1.7-2 hours, the speed is about 25KM/H, and the continuous mileage is 43-50 kilometers. Of course, this is only a theoretical value. Actually, it is impossible to run so far. There is an error of about 10 kilometers. Actually, it can run 33-40 kilometers.

can you understand? Running 25 kilometers is indeed a little less.

"The car repair may be the power consumption of the Emma car", explain this to you.

You asked him to test whether the motor consumes electricity. There is no dynamometer in the place where the car is generally sold. It is impossible to measure the efficiency of the motor and the actual working current. Use a multi-meter to measure the discharge current of the vehicle at a constant speed.

The measurement method is to adjust the multi-meter to the current level of 10A. The string is between the positive pole of the battery and the positive pole of the controller. The person rides up. After the speed is stable, how much current is seen? Is it 6-7A?

48V12A electric car battery, 4 batteries, how many kilometers can you normally run? Changing the battery requires 4 one...

A: The mileage is related to the motor power. For example, the motor power is 350W, the battery is 48V12AH, and the theoretical mileage can reach 40 kilometers. The theoretical mileage calculation process is as follows: 1) uniform average current = power / voltage = 350W / 48V = 7.3A; 2) travel time = battery capacity / average current = 12AH / 7.3A ≈ 1.6 hours; 3) 25 km per hour Hour meter

x This battery is very hot recently, brother also went to buy a block, it seems to be a new product, the store cannot buy this battery, can only buy online.

The installation is fairly simple. The original four lead-acid batteries were removed, and one of the suitcases was short-circuited, and the other was equipped with a lithium-ion battery. . The wiring seems to use flame retardant materials. I can't burn it for a long time, only cut it with scissors. . The battery charger and Emma's character interface are compatible and easy to install. Other electric vehicles may have to change the charging socket.

My electric car is the smallest type of pedal electric motorcycle (motorcycle model, not a bicycle model), and the motor should be about 350W. .

Test environment: The temperature at night is about 20 degrees.

The test process: driving at the fastest speed of the electric car, of course, there is no less traffic light or brakes in the middle, and the acceleration is accelerated. Very limited use

A total of more than 35 kilometers ran, the car is out of power. .

Advantages: The top speed can be increased from 42 kilometers of lead acid to 42 and the body is lighter than ten kilograms. It is farther than the lead-acid battery and can be more than 5-10 kilometers. If the speed of normal opening is slow, it can be no problem to drive to 4,50 kilometers.

Disadvantages: The car is light, and it feels strong when it is turned on. Low power (the power indicator counts from the point at which the highest point on the meter is dropped) is easily exhausted and should be seven or eight kilometers. After the car could not be opened, it didn't take long for the lights to go out automatically. . . The original lead acid can be opened for a long time under low electricity, which should be caused by the difference in the optimal use voltage between the lead-acid battery and the lithium battery.

I am also a Tanon 48V12AH battery. The farthest time is fully charged. When I unplug the power supply, I will go 55 kilometers and go to zero to stop. This was the farthest time, when the electric car was bought for a few months. The speed of the ride is 25 kilometers, because the top speed of the car is so fast. If the speed of other cars can reach 35 kilometers per hour, it is almost impossible to run at full speed and 50 kilometers.

The slower the electric car is, the more mileage it can run.

The electric vehicle of Tanon Battery 48V12AH can run 40--50 kilometers in general, and the old battery is based on actual conditions.

Now electric cars want to run farther:

1. You can choose some large-capacity battery electric vehicles such as 48V20AH when choosing an electric car.

2. Electric vehicles can use the new parallel electric car charger. The electric vehicle of 48V12AH is fully charged for 1 to 2 hours. This can avoid the electric vehicle not being used enough. It should be on Taobao, and it can also avoid the electric vehicle being out of power.
