If the meter that shows the power of the electric car is broken, does it affect the car? Is it dange

It has no effect on the car, but after the power meter is broken, because you can't grasp how much power your car has in time, it is possible that the battery will lose power, once the battery loses power. It will sharply reduce the lifespan by 80%, so there is still a certain harm.

The power switch is damaged, and the instrument cannot be powered on normally. If the power switch is not in good contact, there is no way to power the meter of the electric vehicle. In this case, it is generally necessary to inspect and repair the poor contact of the power supply cable.

If it still doesn't work, you'll need to replace it with a new power switch.

The battery connection is poorly contacted, resulting in an unstable power supply. This is the reason why the battery is not connected properly, because the connection line is not in good contact, the battery power supply will be unstable, so it will not be displayed. For this problem, you need to check if the connecting cable is loose and reconnect.

The fuse is blown and the power supply cannot be connected properly. In some times that we don't know, the electric vehicle will blow the fuse for some reasons, resulting in the meter cannot be powered normally, resulting in the meter cannot be displayed. At this point, we have the option to replace it with a new fuse.

If the electric car is faulty, the instrument panel will display it. When the screen continues to light up a gear, and there is a capitalized M icon inside, this is the motor of the electric vehicle has failed, and there will be symptoms of weak rotation and abnormal noise.

When a yellow faucet light is on, it means that there is a problem with the ECU computer of the electric vehicle, which is the core control device used to control the start, operation, advance and retreat, speed, stop and other electronic devices of the electric vehicle motor. If the power supply circuit of each sensor inside the ECU is short-circuited or open-circuited, and the components are burned out, it will cause the vehicle to operate abnormally.

When there is an exclamation mark in a slogan, in general, it is because of the excessive wear of the brake pads, the elasticity of the brake spring and the breakage, which will lead to the failure of the brake power-off system device, and the vehicle can not drive in the state of electricity.

When a red battery icon appears, it means that the battery of the electric vehicle has failed, and the power supply cannot be supplied normally for some reason, which may be caused by a small problem with a battery in the battery pack, and the voltage capacity and internal resistance of the battery are inconsistent with other batteries. It is also possible that the battery has an open circuit fault, resulting in excessive resistance due to disconnection somewhere in the circuit, and the current cannot pass through normally. The faulty battery needs to be replaced and the circuit needs to be serviced.

Precautions

When the electric car fails, we must send Yantong to the maintenance plant for maintenance in time, sometimes do not pay attention to some reminders, ignore, the consequences will be very serious, and even lose their lives, to always put Ansexun in the first place.

1. The three core components of electric vehicles. Batteries, controllers, motors. When making finished products from electric vehicles, we try not to modify them privately, such as installing battery packs, and the current and voltage of the controller and motor do not work within their normal range, which will affect their life.

2. When charging, the output should be connected to the electric vehicle first, and then the plug should be plugged into the power supply for charging. And vice versa, when charging is complete.

Unplug the power supply and then the output connector.

3. The charging time for the battery is generally 8-10 hours. Based on the electric vehicle charger charging for 2 hours after the green light is on, the first electric car can be charged for an additional 2 hours after the power is exhausted.

4. It is best not to slam the "accelerator" when the electric gear stop car starts. One is because the instantaneous current is too large and easy to cause accidents, and the other is that excessive power loss also damages the battery, electric vehicles do not wait until the last point of power is exhausted before charging, the standard of measurement is 30% of the total power, and do not run out of power to force the electric car, the battery is damaged.

5. Electric vehicle braking method. The braking sequence should be the front brake after the brake, and the situation is urgent, do not brake suddenly, hold the brake lightly and brake little by little, especially if the disc brake is installed.

After all, the electric car is two-wheeled, and the sudden braking will cause the electric vehicle to swing irregularly, which is very easy to cause a stupid accident. In addition, grinding tires will also greatly reduce the life of tires.

1. The battery box is seriously heated.

In general, when the battery is charged, the case is definitely hot, but not hot. If the EV battery is seriously heated when charging or discharging, or even the charging drum phenomenon, the battery has been scrapped and cannot be used again.

The reason for the heat generation of the battery is that the active material on the plates is severely detached, which is an irreversible process. However, if it is severe enough to inflate the package, it can even cause the battery case and circuitry to burn out.

2. The battery is not charged.

If you find that the battery cannot be charged while charging, do not rush to check whether the charger is damaged and whether there is a problem with the connection of the charging circuit (such as whether the wiring and plugs, sockets, and plugs are in good condition). If the battery is in good condition, the battery may be damaged or have a longer life.

3. The charging time is short, and the riding time is less than 5km

For example, the battery will be fully charged quickly (less than half an hour), but driving less than 5 kilometers indicates that the battery is in a state of end-of-life, which is due to the aging of the battery. If the battery life is not long, you can go for repair, if it is longer (more than 2 years), it is recommended to replace the battery.

Hello, I'm helping you sort out the answer to your question, please wait a while Hello friend, if this battery car, the meter is inaccurate, this is all your controller problem, a little more. Because this is all this signal, it is the controller given by the controller to detect the battery voltage, and then give this meter display. You can try this out with a friend by changing the controller.

Hello me, when I am riding, the electric sand car is unstable, one will be full, one will show no power, and the walking will stop, is there a problem?

This is a bit more of a controller problem. First, replace the controller. Anything else should be fine, or check if the controller wiring is loose? If this burns out, it can also cause this problem.

Summary. Hello. Friend.

At present, the LCD dashboard of an electric car cannot be repaired if it is broken, because it has no accessories. You can go to the car shop for a free warranty replacement.

Hope it helps.

The electric car dashboard is broken.

Hello. My friend's current LCD dashboard of an electric car can't be repaired if it's broken, because he has no accessories. You can go to the car shop for a free warranty replacement. Hope it helps.

I hope you can give me a thumbs up, your thumbs up are important to me, thank you.

I bought a new plug and burned out.

I bought a new plug and burned out.

Hello, glad for your question. I'm Xiaolong, an auto repair consultant. With 10 years of experience as a senior fitter in automobiles, he is currently working in an automobile manufacturing company, and has provided comprehensive automotive repair and maintenance consulting for more than 10,000 customers.

We are typing the answer by hand, so please be patient for a while. I'll give you a solution in a few minutes, thanks! <>

Generally, there are three situations: 1. The line behind the fuse or the electrical appliance is used to tie the iron; 2. The electrical appliance behind the fuse fails, and the power consumption increases; 3. The electrical appliances after the fuse start frequently, that is, the frequency of starting and stopping during work exceeds the normal use rule. Check it out, friend.

I hope you can give me a thumbs up, your thumbs up are important to me, thank you.

Is it possible that my EV relay is broken.
