Ask a question about an electric car and ask someone to advise you

In the case of motorcycles, it is rare to get 5k.

**There are some domestic cars that are sold** can also be licensed if they are not high, which is a good choice.

The answer depends on what kind of person you are.

From a utilitarian point of view, the obvious choice should be to pull the lever and save five people and kill only one. But critics of utilitarianism argue that once you pull the lever, you become complicit in immoral immorality—you are partly responsible for the death of a single person on the other track. Others, however, believe that being in such a situation requires you to do something, and that your inaction will be equally immoral.

In conclusion, there is no such thing as perfect ethical behavior, and that's the point.

The tram puzzle was first developed by the philosopher Philippa. Ford's 1967 book The Twin Effects of Abortion and Dogma was used to critique the major theories in ethical philosophy, particularly utilitarianism.

Psychologists have found that most people choose to switch tracks when faced with the first situation: they can switch tracks and let the tram hit one person, or they don't switch and let the tram hit five people.

It definitely has an effect, the first few times it should be fully charged, and then used up and then refilled, so that the maximum energy of the battery can be activated! Otherwise, the battery may not reach the calibrated range!

1. Under normal circumstances (not often taking people, not climbing all day), it is best to charge only after 60%-70% of the longest continuous mileage on the manual, which can not only avoid the early capacity loss of the battery, but also avoid over-discharge.

2. If you often take people and climb slopes, it is recommended to drive to 50% of the longest continuous mileage on the manual to charge.

3. If you usually drive very little, and you don't drive to 60%-70% of the longest continuing mileage in a week, it is recommended to charge it once.

4. If you go out or don't open it for a long time, it is recommended to charge it once a month.

5. In any case, the charging time should not exceed 8 hours, especially in the case mentioned in the point, not more than 5 hours.

The performance of electric car batteries or other batteries is similar! They are all memorable, and it is best to run out of electricity before rushing if it does not affect travel!

Honestly, it depends on what you're for. If it's a simple commuter, it's an electric car, and if it's a delivery, it's recommended to buy a motorcycle tricycle. Affordable electric vehicles are no cheaper to gas than motorcycles.

12A and 20A are battery capacity, which has nothing to do with horsepower, the size of horsepower depends on how many watts the power of the motor is, and the motor has a large wattage.

3000 is a bit more expensive in the countryside! It's okay to be in the city! Our country is generally around 2700!

The electric car can't go uphill has nothing to do with the battery! As long as the mileage is reached, it's not about the battery! It is related to the power of the motor and controller!

In fact, the "trump card" of electric vehicles is the first time I have heard of it! We have electric motorcycles here that do well "Oppai", "Ingclair" or something! There are many bicycles!

"Immediately" is a new brand, it's okay! There are many, many things like "Amini", "Jetma", "Dark Horse", "Emma", "New Day", "Oss" (this is not recommended if you go uphill a lot)! For the battery, look at the battery brand, in addition to the "Xinri" has the "Xinri battery" customized in other manufacturers, now many electric vehicle manufacturers do not match the battery, and no matter what battery is sold commercially!

The battery 48v20ha of the best "Tianneng" "Chaowei" to more than 800! 48v12ha is about 500! (Tianneng has a new 48V12HA good battery, the retail price is around 560, and the shelf life is three months more!)

Even if the motor power is the same, just like "Oss", the flat road speed is fast, but the climbing is not good! The power can't be said to be small! But no one else has found this to be the case!

There is a load king bicycle with a large climbing force, 20ha, very old-fashioned style, uphill just now! But the sales are not much, and there are many places that have not been sold!

After the electric car 72V is added to 84V:

1. The speed is increased a little, normal.

2. The stroke is close to the battery failure.

3, electric vehicle 84V is composed of 7 batteries in series, the capacity of these 7 batteries must be the same, if there is a battery capacity lower than other battery capacity, then it is equal to the power used by the electric vehicle is the power of this low-capacity battery, such as this low-capacity battery 18ah, other batteries 20ah, electric vehicles can only use L8Ah, that is, there is a battery without electricity can not be used.

The controller is too big, and 1000's will do.

There is a problem with the charger, and it must be matched.

The battery does not make a sound.

Reasons for the ringing sound:

It is mainly caused by the motor, and there are others such as loose screws on the appearance, the coil of the motor has not been impregnated with paint as a whole, and it will shake slightly when the controller outputs high-frequency current, and therefore cause the whole car to resonate at a certain speed (the resonance must be cleared at a certain frequency).

You can lock all the screws of the whole car (all I can say is that if I call you to lock those key ones, those descriptions, I'll type them here). If it is still the same, you can remove the motor and reinstall it. If it doesn't work, you can try to dip the paint in the hole!!

There is also a way to change a controller, because now the working pulse width and frequency of the controller of different manufacturers are different, and it will not be changed to a high frequency.

Or don't deal with it, it doesn't matter much, it won't affect the life of the car.

When the discharge current is relatively large (that is, the sudden acceleration is fast), the power display is less, and the power is the remaining situation when the speed is stable.

Depending on how you use it now, you can charge it once every 3 to 5 days.

The battery is not well charged for a long time and is easy to vulcanize.

It's not good to charge every day, and it's easy to run out of water. Over-discharge (based on actual usage) is also not good.

First of all, you must know the power of your car and the parameters of the battery. Then you can know.

The current during the ride is calculated as 10A.

Turn on the electric car and let the key see the indication of the ammeter, which is generally charged below one bar. It's almost the same as once a week.
