How many volts is the horn of a 48V battery car? Packed there ? How is it controlled ?

12V, installed in the front of the car, controlled by the button under the handlebar voltage on and off, if it is a fall, you may wish to check which control button of the horn first, under normal circumstances, the probability of horn damage is relatively small.

Generally, there are two plus or minus power supplies, two left and right turn signals, and the last one is the speaker wire.

After pressing the horn switch, use the voltage block of the multimeter to detect the voltage at both ends of the horn connection, and if the voltage is normal, the horn will be damaged. If there is no voltage, the horn switch is damaged or the conductor is broken. The horn switch is short-circuited to the test to quickly find the fault point.

If the positive and negative poles of the electronic horn are reversed, the horn is silent.

The general horn is 12V, installed in the front of the car, controlled by the button below the handlebar voltage on and off, if it is a fall, you may wish to check which control button of the horn first, under normal circumstances, the probability of horn damage is relatively small.

The horn is not on the controller at 48v**, it may be in the dial or under the front insert. Generally, it is good to change the DC 48V voltage, and it is generally 10-15 yuan in the repair shop.

Not necessarily, there are 12V, 24V, 36V, and 48V, but the commonly used ones are 12V, you can ride the bike to the repair and change it, about 10 pieces, up to 15 pieces.

The twelve-volt one, like the motorcycle one, is under the headlight panel. More than a dozen fast oceans. It's easy to change, just plug and unplug.

There are two types of electric vehicle horns, one is 12 volts and the other is 48 volts.

The voltage of the electric vehicle lighting horn is 12V direct current.

That is to say, all the devices on the electric vehicle use the output voltage of its battery 12V. Electric vehicles use batteries as energy**, and convert electrical energy into mechanical energy through controllers, motors and other components.

Movement to control the magnitude of the current to change the speed of the vehicle.

Daily maintenance knowledge and precautions.

Pre-driving inspection: check whether the brakes are flexible, whether the lighting and horn are normal, whether the tire pressure is sufficient, etc. If there is any abnormality in the vehicle, please go to the service point for repair in time.

Every 200km interval of the vehicle, check whether the U-bolt is loose under load, and tighten the nut evenly if it is loose, and repeat it 2-3 times; Slow down when crossing roadblocks and changing lanes, as it is easy to cause damage to the vehicle or even roll over if the speed is too fast.

There are basically two common electric vehicle horns. One is a 48-volt horn for a 48-volt electric vehicle. The other is to use a voltage converter to turn it into a 12-volt general-purpose horn, ie. 12 volt electric horn.

The horns of electric cars are available in 48-volt and 12-volt versions. Basically, that's all there are. 12 volt horns need to use a voltage converter.

With the rapid development of science and technology, speakers are universal from 12 volts to 72 volts.

Electric two-wheelers, divided into electric bicycles, electric mopeds and power motorcycles. According to the new national standard, there are requirements and configuration standards, but the latter two types have no specific requirements for the motor and battery configuration, the first type of battery configuration is up to 48 volts, and the maximum power of the motor configuration is 400W.

The electric moped and power motorcycle battery configuration is 60 96V, and the motor configuration is 500 1200W. The model distinction of the motor: choose the speed, run fast, have a long range, and have strong power, most people will choose mopeds and power motorcycles.

The configuration of the battery is different, and the configuration of the motor is also different.

The motor configuration of the moped, such as 500W, 650W, 800W, 1000W, the batteries installed in these configuration motor models are also different, according to their own choice, with the appropriate battery.

The 12 amp battery is a 350 watt controller, and the 20 amp battery is a 500 watt controller.

The 48-volt 350-watt motor is divided into two types, one is a 48-volt 12-ampere battery that can run up to 40 kilometers to 45 kilometers in a brand new electric vehicle, and if it is an electric vehicle that has been used for more than two or three years, the safe new battery can only run about 40 kilometers. The other is a 48-volt 20A battery, and the new electric car can run up to 40 50 kilometers, and the distance of the car after two or three years of use is about 40 kilometers.

Introducing the 350W motor, which has a maximum speed of 30 km/h.

400W-450W full-disc motor is 40km h, and electric motorcycle motor above 500W is above 50km h (including 50km h).

A car with a 48V12Ah battery and a 350W motor can run 60-80 km under normal circumstances, and a car with a 48V20Ah battery and a 500W motor can run 80-100 km under normal circumstances.

These data are all in good condition, flat roads, and not overloaded. The actual mileage is related to various factors such as vehicle conditions, road conditions, and load. And as the capacity of the battery decreases, the mileage will gradually decrease.

The controller matches with the voltage, greater than 48V, between 72, the controller mainly looks at the current limit, which determines the starting speed, and the top speed depends on the motor.

The 12 amp battery is a 350 watt controller, and the 20 amp battery is a 500 watt controller.

The horn is 12 volts, including the lamp, which goes through a step-down circuit module to output 12 volts to power the horn and the lamp.

1) "Vehicle" means motor vehicle and non-motor vehicle.

2) "Motor vehicle" refers to a wheeled vehicle that is driven or towed by a power unit and driven on the road for personnel or for transporting goods and carrying out special engineering operations.

3) "Non-motorized vehicles" refers to vehicles driven by human or animal power and driven on the road, as well as motorized wheelchairs for the disabled, electric bicycles and other vehicles that are driven by power units but have a design maximum speed, empty mass and external dimensions that meet the relevant national standards.

Precautions for electric vehicles.

When using electric vehicles in summer, try to pay attention to the safety of the battery, because the weather is hot, and the battery has been heating during the use of the electric vehicle, so the safety hazard of the battery is a very big problem, which is easy to cause spontaneous combustion of the battery, and we must pay attention to the ventilation and heat dissipation of the battery, as well as avoid the exposure of the electric vehicle battery to the sun.

Some 48V electric vehicles (and even some electric tricycles) are powered directly by the battery pack, and the accessories manufacturers can also provide 48V accessories (60V accessories are available online), in order to save the cost of a power converter. At present, the vast majority of electric vehicles are equipped with power converters, and the power supply voltage of the light horn is 12V. On the one hand, you can see whether there is a power converter on the car, and on the other hand, you can measure the working voltage of the light horn.

In the past, the old electric vehicle did not install a converter, so the voltage of the electrical appliances on the car is the same as the total voltage of the car, at present, except for some simple bicycle electric vehicles still do not have converters, basically there is a unified installation and configuration of voltage converters, that is, the total voltage is converted to 12V to the lights and horns on the car.

The voltage of the electric vehicle to the horn is 12V, only the battery lead wire on the electric vehicle, the motor power line is the battery pack voltage, except for the accelerator voltage, the other lines are 12V.

To see whether it is a 12-volt horn or a 48-volt horn, a 12-volt horn, then you need to convert 48 volts to 12 volts through a voltage converter, and the voltage on the channel speaker line is 12 volts.

If it is a simple electric car, the horn voltage should be 48 volts. If it is a relatively large electric vehicle, the speaker cable with the shell should be 12 volts. Larger electric vehicles have a voltage converter. The converter supplies power to horn lights, etc.

It should be 12, because such a voltage is common to motorcycles, and electric vehicles are equipped with a step-down exchanger, and 48 is converted into 12

The small electrical appliances on the electric car are all 12V. Including the speaker, there is a converter to convert 48V to 12V. So the voltage to the speaker wire is 12V

The main switch is 48V. Balance the discharge of each battery.

The 12V speaker is connected to the converter output 12V.

Depending on the model, there are 48 volts, and there are also 12 volts with converters, and you can look at the back of the horn, there is a voltage logo.

<> lithium iron phosphate battery for electric vehicles.

No, only if the motor and controller are 60V universal.

The number of charge-discharge cycles of lead-acid batteries is about 350, the number of charge-discharge cycles of ternary lithium batteries is about 800, and the number of charge-discharge cycles of lithium iron phosphate batteries is about 2000. The storage temperature of lithium iron phosphate battery is -10 35, and the discharge working temperature of lithium iron phosphate battery is -20 65.

Before buying a lithium battery, see if the battery cell used is a product, the quality of the battery determines the quality of the battery, such as capacity and energy density, etc., and then find a lithium battery produced by a large manufacturer, the production process is mature, the after-sales service is guaranteed, and the lithium battery market reference price is 1250 yuan. If you need to run long distances, it is best to install a range extender, with which you are not afraid of running out of power halfway, it can help you gallop without worry.

No, most of the controllers are overvoltage and undervoltage protection, the 48V controller voltage exceeds 58V will be overvoltage protection, the controller can not start the car to accelerate and there is no response, if there is no overvoltage protection of the controller, the motor and the controller may burn out, the battery will also be over-discharged resulting in power loss, and the battery will be scrapped after several uses.

The electric car is a 48V motor, a 48V controller, and a 60V battery. This should not be possible. If the battery voltage is too large, it is easy to burn the motor or controller.

No way! This makes it easy for the controller to burn out. A 48V battery must be used.

The 60V battery must be equipped with a 60V controller, a 60V motor, if a 48V controller is used, it will cause the controller to be damaged due to the high input voltage, if the 48V motor is used at the same time. It will also be damaged by heat generation due to the high input voltage of the motor.

Motors are not allowed;

1. Because the motor winding is designed according to the 48 volt voltage, the current generated by the 60 volt voltage makes the 48 volt winding generate strong heat, which makes the insulation aging and burns out after long-term use.

2 Universal controller is OK because the software is a 48-72 volt universal design.

Such a match is not suitable, because the voltage is not the same, if the controller is 48--60 compatible, that is the beginning, otherwise it cannot be used, because the controller will protect.

The 48V controller should still be equipped with a 48V battery, otherwise the controller is easy to be damaged by overvoltage, and the battery capacity is overdischarged.

Summary. 48V electric vehicle because it is a new national standard electric vehicle, so it needs to accept the trouble of speed limit, the maximum speed of this kind of electric vehicle is only 25 kilometers per hour, there is a lack of driving efficiency, and in terms of battery life is basically only about 50 kilometers, basically one or two days need to be charged. Secondly, 60V, 72V electric vehicles, although they are all motor vehicles, but there are certain differences, 60V electric vehicles are usually equipped with motor power will be less than 72V electric vehicles, so there is no 72 electric vehicles in power, generally equipped with 600W motors, greater than 48V 400W, but far less than 72V 1000W motor power.

In addition to the difference in power, 60V electric vehicles basically belong to the classification of electric mopeds, its maximum speed can reach 50 kilometers per hour, far greater than 48V electric vehicles, and 72V electric vehicles can break through the 50 kilometers per hour speed limit, has been and 48V electric vehicles in speed can not be compared.

What is the voltage of a 48v electric vehicle to the horn wire? Thank you.

48V electric vehicle because it is a new national standard electric vehicle, so it needs to accept the trouble of speed limit, this kind of electric vehicle speed is only 25 kilometers per hour, lacking in driving efficiency, and in terms of battery life is basically only about 50 kilometers, basically one or two days need to be charged once. Secondly, 60V, 72V electric vehicles, although they are all motor vehicles, but there are certain differences, 60V electric vehicles are usually equipped with motor power will be less than 72V electric vehicles, so there is no 72 electric vehicles in power, generally equipped with 600W motors, 400W greater than 48V, but far less than 72V 1000W motor power. In addition to the difference in power, 60V electric vehicles basically belong to the classification of electric mopeds, its maximum speed can reach 50 kilometers per hour, far greater than 48V electric vehicles, and 72V electric vehicles can break through the 50 kilometers per hour speed limit, has been and 48V electric vehicles in speed can not be compared.
