What should I do if the speed of the electric car decreases when the range extender is turned on?

<>5kw low-speed electric vehicle range extender.

You have to describe how to reduce the speed of the car, whether it starts to slow down slowly after turning on the range extender or does it start to slow down after running for a while? The slowdown of the vehicle may be due to the fact that the range extender is not generating electricity, and the range extender is not generating electricity.

The range extender does not generate electricity?

1.First determine whether it can be accelerated, and idle speed will not generate electricity.

2.Use an ammeter to measure the current and voltage to determine whether the power generation is small or not.

3.Determine if the voltage is too high, and the voltage is low and the power generation is large.

4.Change the rotor.

Because the cruising range of low-speed electric four-wheeled vehicles is still relatively limited, can not fully meet the daily travel needs of the public, if you want to increase its cruising range, you can install a range extender, in order to increase its cruising range, increase its range of activities, meet the daily travel needs of the public, and realize the freedom of travel, no longer due to the lack of power halfway and difficult.

The range extender can be purchased directly from the manufacturer, and the manufacturer will ship it directly, which will be cheaper. It is necessary to choose a range extender produced by a large manufacturer and a big brand to have a comprehensive guarantee of quality, performance, technology, after-sales and so on, otherwise if it is a small workshop-type manufacturer, it is easy to break and there is no guarantee in all aspects.

Recommendations for the use of range extenders:

It is not recommended to start the range extender when the battery is full, and it is generally recommended to start it when the battery is only 30%-40%. There is no particularly good effect when starting when the battery is full, in order to be environmentally friendly, it is recommended to start the range extender when needed, battery pollution is more serious than exhaust gas pollution, and protecting the battery is to protect the environment. It is not recommended to use it when the battery is not a little charged, the range extender is electric when it starts, and it may not catch fire when the battery is not charged at all.

It should be completed at the beginning of the design of the structure of unlimited battery life, so that the market will naturally expand.

There are many kinds of fuel range extenders, if it is a city extender with relatively large power, charge the battery while battery life, as long as there is oil, it can drive normally. If the power is too small, it can only assist the battery and delay the discharge, then it is not an "infinite range extension".

You can run if you have oil, but the cost of oil is several times that of electricity, so it can only be used urgently, and it is not cost-effective to use it for a long time.

A range extender is the equivalent of charging a battery.

Summary. Dear, hello, the electric car runs slower and slower after opening the range extender, because there is no re-issue point during the Zengcheng period, and the state of long-term non-power generation, while the battery voltage drops, the speed will also decrease, such as when the battery car is out of power, the speed is particularly slow, or the speed can not run, the state of stop-and-go.

Dear, hello this J, the electric car runs slower and slower after opening the range extender, because there is no re-issue point during the Zengcheng period, and there is no power generation for a long time, while the battery voltage drops, the speed will also drop with it, such as when the battery car is out of power, the speed is particularly slow, or the speed can not run, and the state of stop-and-go and stop-and-go touches the pickpocket.

Dear, due to the low speed, the range of the electric four-wheeled vehicle is relatively limited, can not fully meet the daily travel needs of the public, if the group core bridge wants to increase the mileage, you can install a range extender to increase its mileage, increase the range of activities, to meet the needs of daily travel.

It is not recommended to start when the normal battery is full, and it is generally recommended to start when the battery is only 30% to 40%.

Hello, I'm very happy to answer for you, electric vehicles are useless to install this, under the current efficiency, the range extender can not increase the distance to change the argument, but the lithium battery is more expensive, so it can still have a certain market space. Range extenders are the chicken ribs that survive between lead-acid batteries and lithium batteries. In the long run, sooner or later, it will be obsolete, provided that no new high-efficiency range extender is developed.

The current situation is that there is no breakthrough in battery technology. It is still at the level of the 90s of the last century. Lead-acid batteries must be eliminated.

Lead-acid batteries** have not changed much, but it is recognized that lead-acid batteries, which could have been used for more than 2 years, will soon be out of use for a year and a half. Lead-acid batteries due to the increase in cost, without mentioning the premise of ** qualification. Life is in general shrinkage.

And there are signs that the lithium battery wild barrage is cutting prices. It is estimated that by 2020 the nuclear ridge will be absent. Lithium batteries** will tend to stabilize.

Battery** drops. The lithium battery market will mature.

Fault phenomenon: the engine only has a low speed, the car suddenly does not speed up after about 15km of normal driving, and the engine ignites. When the engine is started again, it is easy to start, the idle speed is unstable, and when the throttle is increased to the quarter position of the stroke, the engine speed decreases, and there is a tendency to stall; When the oil is turned off, the engine speed increases.

The vehicle can only drive at low speeds, increasing the throttle to medium speed in the early morning and increasing the speed when closing the throttle.

Fault analysis and troubleshooting: start the engine, easy to start, unstable idle work; When accelerating, the engine is responsive at low speed and works well; When increasing the throttle to a quarter of the full stroke, the engine speed drops and has a tendency to stall, when the throttle is closed, the engine speed should be determined for the phenomenon of the car, the cause should be determined first, whether it is an oil circuit failure or a circuit fault or a mechanical fault. The flashover test was carried out at the end of the high-voltage line, and the high-voltage spark strength was normal and the continuity was good; The spark plug was tested for flashover, and the flashover performance of the spark plug was good.

The color of the electrode surface indicates that the combustible mixture is in the right proportion. Plug the spark plug hole with your fingers and step on the starting lever, the gas impact on your fingers is strong, indicating that the cylinder is well compressed. Approve the gas distribution time, gas distribution timing; I ask when I approve the ignition with the ignition timing lamp, and the ignition is also on time.

In the case that the cause of the failure is not clear, remove the connecting pipe between the air filter and the carburetor, start the engine, rotate the oil chain finch door handle back and forth, observe the action of the plunger valve through the carburetor inlet, and find that the plunger valve rises when the throttle is increased, but when the throttle is increased to a certain extent, the plunger valve falls, and when the small throttle is closed at this time, the plunger valve rises again. Given that the car uses a constant vacuum carburetor. According to its characteristics of "the rise and fall of the plunger valve is not controlled by the steel cable, but automatically rises and falls by changing the intake volume of the throttle opening" and the actual phenomenon of the car, it is believed that the vacuum in the vacuum chamber is not enough when the throttle is increased.

Therefore, the disassembly carburetor was examined and a crack was found in the vacuum diaphragm.

Due to the crack of the vacuum diaphragm, when it drives the plunger valve to rise to a certain height, the action of vacuum suction and spring force makes the crack leak, the vacuum degree in the vacuum chamber disappears, the spring pushes the plunger down, and the engine speed decreases. Causing malfunctions. Troubleshoot after road test after replacing a new carburetor.

This tram range extender, its working principle is to increase the voltage of the battery, can squeeze all the remaining power of the battery, in fact, the remaining power of the battery is not much, so after walking for a while, he will slow down or not move, which is actually very hurtful to the battery, it is not recommended that you use the range extender.
