If the battery of the electric car is replaced, it will not show the power, what is going on?

It is obvious that there is a problem with the power point of the power display, it is likely that the electricity it takes is virtual, and the operation can be determined very simply, from the power display meter directly connected to the two long wires to the battery power port, there is no doubt that it can be judged, if it is normal, it is the power problem, if it is still thatHeaderIssue.

The reason why the electric vehicle meter does not display the power level: the first is that the power switch is damaged, resulting in the instrument not being energized normally; The second is the fuse of the vehicle.

Burnout, resulting in the inability to supply power normally; The third is that the connection line of the battery is not in good contact, which makes the power supply unstable; The fourth is that the fuse is not turned on.

caused. Electric vehicles, that is, electric drive vehicles, are divided into two types: AC electric vehicles and DC electric vehicles. It works by converting electrical energy into mechanical energy.

In this way, it is driven by the vehicle, so as to achieve the purpose of automobile movement. As a new energy vehicle, electric vehicles are popular among consumers for their cheap, convenient and environmentally friendly advantages.

As a green sunrise industry, the current development trend of electric vehicles is very good, both in terms of energy and environmental protection.

It has a very big competitive advantage.

For electric vehicle batteries.

There are the following points to pay attention to in the maintenance::

The first is when buying a new car, you need to fully charge the vehicle before using it.

The second is to check whether the rated input voltage is consistent with the power supply voltage when charging.

The third is to unplug the AC power supply first and then the plug connected to the battery after charging.

It has nothing to do with replacing the battery.

It should have touched the line of the dashboard in the process of replacing the battery.

The instrument line connector is disconnected or in poor contact.

Recheck and connect and you're good to go.

If the battery of the electric car is replaced, the battery will not be displayed, and it may not be connected.

There is no electricity source input. Of course, it can't be moved! Host.

The reasons why BAI wants it are as follows:

1. Whether the first electric door switch is in place!

2. Check whether the plug at the electric DAO pool and the output line is loose! Because often shaking during riding will cause the plug to loosen and fall off!

3. Check if the fuse of the battery is blown out! Sometimes, the instantaneous current pulse when the electric gate is opened will also blow the battery fuse!

4. If the cable inside the battery falls off, there will be no power output!

The electric car runs out of electricity, the dashboard shows that the power is still sufficient, and the car does not go, why is this?

There are three possibilities:

1. The battery voltage is too low.

2. The circuit is disconnected.

3. The instrument is broken.

Check method: Step 1: Measure the battery voltage with a multimeter first, if the voltage is lower than 36 volts it is almost impossible to display.

Step 2Turn on the power switch and see if you can get the motor to turn.

Step 3: Change the meter.

That should just be a problem with the battery level display, and there is no problem with battery charging and use.

In this case, you can't ride, and you can't be sure how much you can run based on your feelings, and it's easy to throw you on the road.

It's not a big deal, it's easy to get to the repair shop.

Hello, glad to answer for you! This is a circuit problem. 1：

First, use the meter to confirm whether there is power on both stages of the battery pack. Whether the rated voltage is reached. If there is electricity for the next step, if there is no power or the rated voltage cannot be reached, charge or change a group of electricity.

2: Open the key, whether the vehicle can walk, whether the lamps and other electrical equipment are working normally If you can walk, the electrical equipment is fine, indicating that the instrument is destroyed; If you can't move around, find the front wiring and short the key connector to check if it's a key problem. If the car can move around and the electricity is normal, just replace the whole set of keys.

If the battery is powered and it shows that there is no power, it means that the meter is broken.

Hello, there are many reasons why the electric vehicle battery has an electric meter that shows no power and does not display the power of the disturbed car instrument, generally: 1. The power switch is damaged, resulting in the instrument being unable to be energized normally; 2. The fuse of the vehicle is blown out and the power supply cannot be supplied normally; 3. Poor contact of the battery connection line, resulting in unstable power supply; 4. The fuse is not opened, resulting in the instrument not being displayed, etc. The main manifestation is the decrease in battery capacity, which in turn leads to thermal runaway and deformation of the positive plate, and the expansion of the battery shape.

Because the battery is broken, there are two special forms of circuit breaking, one is the micro circuit break, which refers to the fact that the car is in the process of driving, due to the virtual connection inside the battery, sometimes it will be energized.

Can the electric vehicle battery be repaired if it is fully charged for 4 months, and the meter shows 0?
