What happened when the Wangpai brand Little Turtle King electric car I bought yesterday couldn t be

First, open the key door to see if you can light up the headlights (even if the battery is low).

Second, turn the handlebar, and the wheel hub supported by the double bracket should also rotate without load.

3. Plug in the charger, the red light of the charger indicates that it is in the charging state (the green light indicates that the battery is full).

If the headlight can not be lit and the hub can not rotate, it should be the internal fuse of the battery pack that is burned out, and the fuse with the same current identification is powered on, and then repeat the first, and second, items respectively, if the fuse is burned again, it is a short circuit in the wiring circuit or the controller is damaged.

If the charger indicator light does not light up, it may be that the charger is damaged or the polarity of the charger is not suitable for the charger protection, and the internal fuse is broken, you can find a dealer or experienced technician to help repair it (change the jumper).

Usually, it takes about 10 hours for the battery to be fully charged (it should be noted that it must be equipped with a charger with the same voltage level as the battery), if it can be charged at the beginning, but soon the green indicator lights up, indicating that the battery is fully charged, for the new car is one or more of the battery pack, the battery plate is vulcanized seriously or falls off, resulting in increased internal resistance (common fault of old battery), so that the overall performance of the battery pack is abnormal, and the dealer should be immediately replaced. In order to ensure the consistency of the battery pack, it is best to ask the entire battery pack to be returned or replaced, or find a reputable dealer to purchase another battery pack.

The general situation is that the wire at the charging socket is broken, first change the charger to try it, Wang Pai electric car production area is Linhai City, Taizhou, Zhejiang Province, the overall car is not bad.

The new car has been stored in the merchant for a long time, and the sulfuric acid in the battery has dried up, and some sulfuric acid needs to be added.

There are three possibilities:

First, the charger of the tram is broken. The capacitors on the circuit may have fallen off, broken, or broken wires connecting the battery from the appliance, resulting in the charger light being on but the battery not charging. The solution is to borrow someone else's charger with the same type of interface to try to charge it.

If you can, it is recommended to repair or replace your own charging appliances.

Second, the battery is broken. The wires connecting the batteries in series inside the battery may be fused, or the power cord of the battery charging port may be broken. It is recommended to test it with a mesh meter, whether the resistance of the battery is infinite, if it is, it means that the wire is broken, open the battery box, and connect the wire.

Third, the battery pack is broken. Disassemble the battery box and measure the voltage and resistance of the battery pack one by one. Which piece is abnormal, which piece to replace. Or the battery needs to be woken up, use a charger higher than the charging voltage to charge and wake up the battery.

Look at what brand, is the charger model right?

Don't worry, I don't see anything wrong with the car itself, but the capacity of the battery is not good.

The capacitance will slowly decrease with use, and the voltage will also decrease.

Let's start with speed, if your car is equipped with an actual computer monitor, i.e. the mileage and speed are calculated from the rotation of the front wheels. The measured speed will be more accurate, and the actual slow speed can only indicate that the output voltage of the battery is low. If your car is equipped with a controller computer that measures the speed obtained by measuring the current in the controller, this speed will be more accurate, and the voltage drop caused by the decrease in battery capacitance will be more obvious.

If the quality of the battery you replace is faulty, the capacitance and output voltage will not be able to reach the original level. It is recommended to buy *** brand batteries.

Let's talk about the maintenance of the battery, the landlord uses the little turtle king, the motor power of this car is more than 800w, it belongs to the high-power model, and the speed is much faster than the general electric bicycle. The current in the driving discharge is also large, which is also very important for the loss of the battery. Therefore, develop good driving habits when driving, and do not slam the accelerator when starting at a standstill, which will make the current instantly become very large and hurt the battery.

When encountering a red light in the distance, release the throttle in advance to slow down, and if you brake suddenly, the current will also increase.

The battery capacity is low, often one of the four batteries is not good (we call it bad), use a measuring device to find out this battery and replace it. In addition, pay attention to the electrolyte of the battery in the usual maintenance, and if it is reduced, distilled water or electrolyte should be replenished in time.

My battery has been used for 3 years and still has 90% of the battery power

Your battery should be 48v 20ah.

Generally, it can be at least 40-50 kilometers.

If you can only run 20 to 30 km, it is obvious that there is a problem with the battery.

Is the battery installed? Is the contact good? What brand of battery ? How much did you buy ?

You're too vague to judge.

1.It's not worth it. Go and see for yourself the configuration of the little handsome guy. Let's take a look at their high allocation.

2.The green source should be able to exceed 50But it's too much electricity. The speed is fast, the number of kilometers is less. That can also go up to around 45. But the kilometers are longer.

3.I can't say anything about this. Because a lot of things cost electricity. For example, starting after braking is very power-intensive. And then there's the brake light...

4.These 2 brands are good. It's a bit famous.

5.It doesn't burn, but as they say, it doesn't give full play to the performance of the motor.

6.This depends on your specifics, such as whether it is convenient to charge. Is there a place to put the car.

If it is easy to charge, it should be integrated, that is, the back seat is low. The change they say is to make a hole in the place where you are seated. It's not convenient to put things in the future.

And one is easy to lose if you don't pay attention to the battery. The rear seat lock is very, very easy to open.

7.Personally recommend the second one. Because the 800w motor is enough.

If you find someone to change to 60v20a, you can run at least about 60 miles. That is, now that motor still has potential, but the controller limits him. Also, electric vehicles are designed to have a speed of **, which is easy to cause accidents if it is too fast.

Personally, I don't recommend the one that is too fast.

Finally: 3500 or so cars, minimum configuration: front and rear disc brakes, tubeless. Front oil pressure damper. Smart alarms. LCD screen. Including ABS.

From the configuration point of view, Emma's configuration is unreasonable, and the quality of the brand is only on the one hand, you can't see the height of the configuration, you can't see the instrument and the like, you have to look at the thickness of the shock absorption, the type of brake, and even the tire width, these things are the most important, and many others are useless, and the electric car is not a pointer or an LCD instrument It is the same, but the style.

It doesn't matter if you want to brand the car, because they sell the brand, in fact, why do you install it yourself, just use it for yourself.

The landlord should have bought it, share the experience.

1.You get what you pay for, the high configuration of the green source, the frame, the fork, I didn't say it. But compared with other brands, Emma is also considered to be medium and high-end.

2.According to the configuration you said, the speed and start-up of the green source are stronger, and the actual speed affects the speed a lot. I can't say.

3.According to the configuration you said, Emma's runs farther because he has less horsepower and saves power.

4.The brands are good.

5.The controller is smaller than the motor and does not destroy the motor, but it does not give full play to the performance of the motor, and this situation should not occur in normal original cars, you are sure that it is an 800w motor instead of a 500w ???Or is the seller talking about it, but it's actually a 350w motor and controller?

6.I don't understand, of course, this depends on the demand, if you don't have to take it down to charge, of course it's fixed, it's not good for thieves to steal.

7.If the road is not far and you don't need to run, of course, choose high power. The road is far away, and I can't wait to use a 250W motor. Turtle ran him 80 kilometers.

Typing so many words. Hurry up and adopt it. Bonus points. My hands are sore. You're going to break this down into eight questions. I'm losing by putting one.
