What's the matter with the electric car going automatically without refueling?

The reason why the battery car runs without a gas door is:

1, brushless lathe 1, rotor broken 2, negative wire broken or poor contact, replace the rotor.

2. If there is a brush, the controller may be broken. Replace the controller.

3. The battery car is short-circuited in rainy days or at vehicle speed.

In short, electric cars are driven by electricity. An electric car. Classification of electric vehicles Electric vehicles can be divided into: electric bicycles, electric motorcycles and so on. The first electric car was made in 1834. It is driven by a DC engine. Today, great changes have taken place in various types of electric vehicles. Electric cars are very popular because they save money and fuel.

Extended data:

1. Lead-acid battery (lead-acid colloid battery) has low cost and stable performance. Most electric cars on the market use this battery.

2. Lithium-ion batteries (usually referred to as lithium batteries) have high cost but large specific energy; High specific power; Small self-discharge; No memory effect; Good cycle characteristics; Wide working temperature range; No environmental pollution and the like.

3. The gel battery has high cost and stable performance. There are few electric vehicles using this battery in the market, and only a few businesses are equipped with this high-performance battery, which has the highest safety factor. The service life is far ahead of the advantages of two types of batteries and self-repairing function, which is also the leading position in the industry. The advantage is that there is no lead-acid battery, which avoids the disadvantage of layered lead-acid battery.

4. There are three main driving modes for electric vehicles: one is hub drive, the other is center drive and the other is suspension drive. The electric bicycles in the market are mainly driven by wheel hub, which is better than rear wheel drive, but the front wheel drive performance is relatively poor.

5. Considering the balance of the whole vehicle and the convenience of getting on and off, it is best to put the battery in the inclined tube or vertical tube of the frame, and the configured batteries are basically economical lead-acid batteries. Most electric bicycles use 36V 12AH lead-acid batteries; Because the battery with 24V 12AH has a short continuous mileage, consumers have fewer choices.
