Whether a 36V electric vehicle can be changed to a 48V one, and how to change it

OK. 36v to 48v is the cheapest. Install the charger to change to a 48V charger, in addition to extending the charging time by 2-3 hours, the other effects are the same 2 meters can also be changed to 48V, the display is basically accurate.

The general electric vehicle battery is 12V, three batteries are 36V, and four batteries are 48V. One is that the battery box can't fit another piece, and if the other parts are not replaced, the motor, controller, etc. can be burned.

Member of China Electric Vehicle Alliance: If you want to change your 36V electric vehicle to 48V, you must add a 12V and the original car matching battery, the battery is connected in series when wiring, and the car must be replaced with a 48V controller, and a 12V DC converter, and then a 48V charger, calculated, the money required is also a lot: battery 12V a controller converter a charger 60-120.

Don't change it, let's buy it, controller, charger, battery add up to at least about 160.

You can't use the controller to change the machine.

Who are you, this is my grandfather's number, did you steal it?? Damn, whoever stole it, please return it. By the way, I won't pay you back...

The difference between 36V and 48V is:1.The number of batteries is different.

A 48V electric vehicle is made up of 4 12V battery packs, and the four batteries are strung together to make up an electric vehicle, and 3 12V battery packs are made up, and the 3 batteries are strung together to be 36V.

2.**Different: Same single battery, 3 batteries are cheaper than 4 batteries.

3.Different occupied volumes: 3 batteries occupy a small size, which is very suitable for those small cars.

Hello, I have seen your inquiry, please wait for a moment and answer it for you immediately.

Hello, I am your exclusive technician, attentive, careful, dedicated to answering your car questions, for you to find the corresponding problem solutions and solutions! Differences: 48 volts are faster than 48 volts, and 48 volts are equipped with more motor power than 36 volts.

The speed is also fast. 1.The main difference between electric vehicles is that the voltage is different and the motor power is different.

2.The more powerful the motor. The higher the battery voltage, the faster the acceleration and the faster the speed.

3.The lower the battery voltage, the slower the acceleration. Generally, only small trams are equipped with 36-volt batteries.

1. The number of batteries: 3 and 4 respectively, most of the batteries on the market are 12V, 48V.

Electric car. It is made up of 4 x 12V battery packs, and 3 x 12V battery packs are used for 36V electric vehicles; 2. **Different: the same single battery, 3 batteries are cheaper than 4 batteries; 3. The occupied volume is different

The 3 batteries occupy a small size, which is very suitable for those small cars.

36V and 48V batteries generally refer to the length of electricity consumption, while 48V batteries are used for a longer time. To put it simply, the higher the voltage level, the larger the drive motor; The larger the motor, the more power. If you want to walk a long way, or the road conditions are relatively poor, you need to choose a high-voltage electric bicycle, that is, a 48V electric bicycle.

Specifically, 48V is usually assembled from 4 12V batteries and 36V is assembled from 3 12V batteries. The 48v battery has certain advantages in speed and range due to its extra battery and high voltage. If the battery of 48V is 16A, it can run about 45-50 kilometers on a single charge, and if it is 20A, it can run about 60 kilometers.

The 36V can only run about 35 kilometers at most, and the battery needs 14A. Because of the low voltage, the uphill ability is far inferior to that of a 48V car. The higher the battery capacity, the higher the battery.

In short, what kind of bike you want depends on your mileage and incline. It is better to choose a normal bike type, which has a low failure rate, and can be manually assisted when going uphill, which can reduce the probability of damage to the battery, motor and controller, and the battery life will be longer.

The capacity of these two batteries is different, and the 48V electric car has a longer range and is more powerful. But 48v electric cars** are also more expensive. Electric vehicles are a very common means of transportation, this means of transportation is very light and flexible, and electric vehicles are very suitable for driving in congested urban roads.

The structure of electric vehicles is simple, cheap, and the cost of use in the later stage is very low, so this means of transportation is loved by many consumers.

There is a difference between a 48-bit electric vehicle and a 36-bit electric vehicle, which means that the applicable voltage of the two electric vehicles is not the same, and its power is also different.

48-volt electric vehicles and 36-volt electric vehicles, the battery voltage is different, and the motor controller is also different.

The electric car was originally powered by 60V, and it cannot be directly changed to 48V power supply.

There are two ways to change a 60V electric car to a 48V one, but it is not recommended to change it this way.

1. The original 60V motor and controller are not changed, but the 48V voltage is raised to 60V voltage to continue to provide power to the car. However, through such a transformation, this boost circuit needs to consume a certain amount of power, but wastes energy, and the change is of little significance.

2. Because the controller, motor, and all electrical appliances in the 60V electric vehicle, including lights, etc., are designed according to the 60V voltage, if you want to use a 48V battery, the electric vehicle must be greatly changed, and all the electrical appliances must be changed to 48V. It's actually not worth doing such a makeover.

No. 48V is usually equipped with 4 12V batteries, 36V is matched by 3 12V batteries, 48V batteries are also high due to the voltage of one more battery, so there are certain advantages in speed and mileage, which is usually inseparable from the power of the motor, 48V such as the battery is 16A, a charge can run about 45-50 kilometers, if it is 20A, it can run to about 60 kilometers, and 36V can only run about 35 kilometers at most.

Schematic diagram of series and parallel connection.

The first diagram below is in parallel, and the second diagram is in series.

<> specific process: the 60V power supply of the electric bicycle is to connect the 5 groups of 12V batteries in series with the core of the rental core, the positive electrode of the first group of batteries as the positive pole of the total power supply, the negative electrode and the positive electrode of the second group of batteries are connected, and the negative electrode of the fifth group of batteries can be used as the negative pole of the total power supply.

Compare the advantages and disadvantages of 60V electric vehicles with 48V.

First, ** is different.

The ** of 48V electric vehicles will be lower, and the ** of 60V electric vehicles will be higher, for the average person, both can meet the needs of transportation.

Second, the configuration is different.

The battery pack of 48V electric vehicle is generally made up of 4 12V batteries in series, and the 60V battery is connected in series with 5 pieces, and the motors, controllers, tires, brakes, etc. are different, and the configuration of 60V trams will be relatively higher.

Third, the power is different.

Generally, the motor power used in 48V electric vehicles is 350W, and the motor power of 60V electric vehicles will be higher, 600W or 800W.

Summary. Hello, how to step down the DC 48V voltage to 36V, and then use it on the 36V 250W brush motor, because the current of the 36V 250W DC motor can reach 7A, and it will be higher than this value when starting, so the series adjustable voltage regulator circuit can solve the problem.

The following is a circuit diagram of this step-down circuit:

The circuit changes the sampling voltage by changing the value of the potentiometer, and with the regulator tube, the purpose of adjustment can be achieved, so that the output terminal outputs a voltage of 36V.

In the above figure, adjust the flow tube Q1 to choose 13007 or 13009 transistor, the current of the tube is up to 8A 12A, the withstand voltage value is 700V, and the heat sink is added when using, which can meet the requirements. The voltage regulator tube can be selected from 18V to 24V, and the other can be pressed by the icon.

How to reduce the voltage of electric car 48V to 36V!

Hello, Sen Hao can use the method of series resistance to reduce the voltage, the size and power of the step-down resistance should be calculated according to the current or power of the electrical appliance, I can help you calculate, you just need to send the current or power of the electrical appliance. This has two disadvantages, first, the voltage is affected by the power of the electric appliance, so it can only be used for the electric lead device with the same power of the town. Second, there is a 25% energy loss.

Hello, dear, the replacement needs: replace the capacitor of the controller with 60V400UF converter just convert 48V to 12V can only be used for lighting, not for power system! The motor can not be replaced.

To change the following things: 1. The original charger is changed to a 48V charger, except for the charging time is extended by 2-3 hours, the other effects are the same. 2. The instrument can also be changed to 48V, and the display is basically accurate.

3. Add a second-hand 12ah battery with a capacity of not less than 80%. 4. The controller is transformed to 48V, and there is no need to change the controller.
