What will happen if the battery car controller does not match the battery voltage?

Hello:Electric vehicle controllersIt has the function of protecting the battery.

When the battery voltage drops toRated voltageWhen the times are reached, enter the protection program: cut off the power supply of the battery to protect the battery from being damaged by over-discharge (the damage caused by over-discharge is irreversible).

The controller of the electric vehicle does not match the rated voltage of the battery, and the function of protecting the battery will be lost.

The battery voltage is lower than the control voltage of the controller, which will make the controller misjudge and make the battery unable to supply power normally; If the battery voltage is higher than the controller voltage, it will also damage the controller.

Correct configurationIt should be: battery, controller, motor.

The rated voltage of all three is the same.

will affect battery life.

Generally speaking, the factors that affect the battery life can be divided into: the performance and quality of the battery itself, the factors that cooperate with it in the electric vehicle, the use of the user, etc.

In an electric vehicle system, there are two main factors that affect the life of the battery, one is the efficiency state of the motor, and the other is the design of the charger. If the efficiency range of the motor is narrow, the power consumption increases, and it often works in the low efficiency area, and the inside of the motor is easy to heat.

When the temperature is high, the magnetic material.

There will be irreversible demagnetization, and over time, the efficiency will further decrease, thus entering a vicious circle, and the power consumption of the electric vehicle will increase significantly, even if replacing the battery with a new one will not help. Brushes.

Wear and tear on components such as planar converters and gearing systems can also lead to reduced motor efficiency.

The voltage is high, the controller will be broken, and the voltage is low.

EV charging is simply a charger to a battery pack. Without going through the controller.

To charge the battery, as long as the 220V mains power is converted into the DC power required by the bicycle through the charger, it can be charged, and the charging process does not need to go through the controller.

The battery is to provide power to the electric vehicle, and the controller is to control every action of the electric vehicle The electric vehicle controller is used to control the start, run, advance and retreat, speed, stop and other electronic devices of the electric vehicle The core control device is like the brain of the electric vehicle and an important part of the electric vehicle.

At present, electric vehicles mainly include electric bicycles, electric two-wheeled motorcycles, electric tricycles, electric three-wheeled motorcycles, electric four-wheeled vehicles, battery cars, etc., and electric vehicle controllers also have different performance and characteristics because of different models.

To charge the battery, the battery is generally charged directly without going through the controller. Please see the circuit diagram.

will affect battery life.

If the motor and controller can be matched (about the same power), this combination can increase the driving range. However, it is best to match the battery with a protective plate, if it is not equipped with a protective plate, it will affect the battery life.

If the power of the motor is much higher than that of the controller, the flat road may meet the requirements and travel farther than the original mileage, but the uphill may be de-energized.

Because the motor requires more power, the current required will also increase, and the controller has overcurrent protection, and the maximum output current is a given, so overcurrent protection is possible.

Summary. Hello, I am your exclusive service technician, attentive, attentive and careful to help you solve the problem of using the car The voltage of the electric vehicle battery is inconsistent, mainly in the normal standard, the voltage above 12 volts is not much impact, but if there is a voltage level below 12 volts, when the vehicle battery is discharged, all the batteries are in a balanced discharge, once a battery fails, or the battery voltage is too low, resulting in a decrease in his power storage capacity, When this battery is discharged, it will stop discharging other batteries.

What is the effect of inconsistent battery voltage in electric vehicles.

Hello, don't worry, I can ask for your question, but wait a minute, I need text for about 2 minutes.

How to repair and correct.

Charging repairs can be done using a repair charger.

My car is an electric sedan.

The voltage is less than twelve volts.

It's the same with electric car batteries.

Charging repairs can be performed using a repair charger.

Fixing the charger will do the trick.

Yes, the repair charger can be repaired by charging.

Okay, I'll have it repaired.

Hmmm, okay. Ask a custom message

Summary. What is the effect of the inconsistent voltage of the electric vehicle battery: it will affect the low charging voltage and damage the battery, discharge, it is the conversion of chemical energy into electrical energy, and charging is the conversion of electrical energy into chemical energy and storage.

If the charging voltage is low, all the chemicals in the battery plates cannot be released, and the pole will become lead sulfate, which is difficult to reduce, making the battery capacity smaller, and the battery will be scrapped over time.

Kiss Hello What is the effect of the inconsistent voltage of the electric vehicle battery: it will affect the low charging voltage will damage the battery, discharge, it is the chemical energy that is converted into electrical energy and the leakage is excited, and the charging is the conversion of electric energy into chemical energy and storage. If the charging voltage is low, all the chemicals in the battery plates cannot be released, and the pole will become lead sulfate, which is difficult to recall, making the battery capacity smaller, and the battery will be scrapped over time.

Dear, the inconsistency between the voltage of the electric vehicle charger and the battery will lead to: when the charger standardizer says that the voltage is lower than the battery voltage, it will not be able to charge; When the nominal voltage of the charging companion is higher than the battery voltage, the battery will be charged, and even the reed potato will only cause a fire or **.

(1) Check the power management circuit and use a multimeter to measure whether the output voltage at each point is correct. If there is a problem, locate the damaged component and replace it. If the voltage at each point is normal, perform other searches.

2) Check the interface with external functional parts. Focus on the interface section with the handlebar and brake lever. Find the input pin of the rotary handle on the main control chip, turn the rotary handle, and measure whether the voltage value of the point changes from small to large voltage (generally 1-4V).

If there is no change, it means that there is a problem with the input loop of the handlebar. If it is normal, find the brake input pin on the main control chip, measure whether the voltage of the pin is normal, and judge whether there is a problem with the brake input circuit once.

The output voltage of the electric vehicle battery is normal, the input voltage of the controller is abnormal, and the whole vehicle is out of power.

Hello, the most typical thing is that the pusher motor has resistance, disconnects it from the controller, and the resistance disappears, basically you can judge that the controller is damaged. In addition, it will also show the slow speed, shaky start, weakness of the moving car, and the reaction of the car without gear. Workaround:

Due to the importance of the controller, it is generally not recommended to repair it, because the repaired controller will not last long, so it is recommended to replace it directly.

Recently, a friend reported to me that the speed of its electric car is unstable, mainly manifested in the fact that the car can not be seen to be idling, and the speed will be unstable when running on the road, what is the reason? How to solve it? For this problem, let me explain to you today that there are five main reasons for the instability of the speed of electric vehicles.

1. Poor contact of the brake power-off switch.

If the brake power-off switch is in poor contact, it will cause the electric loss to pay the speed of the motor car is fast and slow, and it is unstable. For such situations, users can try to brake the car a few times to see if there is any recovery, and if it does, it can drive normally. If it doesn't work, you have to check it out with the mechanic.

2. The battery screws are loose or the battery wiring is in poor contact.

Check to see if any of the screws inside the battery are loose, and if so, tighten it. In addition, you can also check whether the battery wiring is in poor contact, and if so, it can be restored.

3. Ablation of key door switch contacts.

Check whether the key door switch is ablated, and if there is ablation, the speed of the electric vehicle will also be unstable. For such cases, the only option is to replace the electric gate switch.

Fourth, the motor Hall wiring contact is not high, there is no good or Hall is damaged.

If the motor hall wiring is not in good contact, the speed will also be unstable, and for such cases, it is good to repair the wiring. If the speed is unstable due to Hall damage, you can only choose to replace Hall.

5. Controller failure.

Of course, it is also possible that the controller is faulty and the electric vehicle degree is unstable, and it is enough to replace the controller in this case.

Of course, if you still can't solve the situation of unstable speed of the electric car, it is recommended to find a professional maintenance master, because if you don't repair it, it is likely to cause new problems because of this one problem. However, in daily life, we should also pay attention to strengthening the maintenance of electric vehicles, so that the service life of electric vehicles can be greatly improved.

Answer: The battery is unstable and clanging when walking; Wu Kong should be asked to go to the place where the electric car was repaired to test it. The reasons for the voltage instability of electric vehicles may be:

1) The power supply line and plug are not in good contact. (2) The controller is not working properly. (3) The position of the handle changes (caused by the rider's unskillful technique).
