Which gear should an electric tricycle choose to climb a hill
When electric vehicles are driving, generally choose 2 or 3 gears to climb.
2nd gear is generally the power gear, which can get the most traction.
3rd gear is high-speed gear. Although the driving speed is fast on flat ground, it is not as good as 2nd gear when climbing.
Many people have a misunderstanding about electric vehicle climbing, I think it is the same as a fuel car, and it needs to use a low gear to climb the slope, But in fact, fuel vehicles use first gear to climb hills because first gear can obtain maximum traction for fuel vehicles.
The first gear of a fuel vehicle uses the smallest gear as the input wheel and the most significant gear as the output wheel.
The principle of leverage is applied, and the maximum torque is obtained by significantly reducing the speed.
But the electric vehicle is different, and the motor mainly power it The 1st gear primarily uses the economical way of driving at low speed and low power consumption.
It is not as powerful as the 2nd gear in terms of traction, and it is not as good as the 3rd gear.
If you use slow gear to climb the slope when the slope is long, you will not be able to climb up, but it will also quickly cause the motor to heat up, causing the controller to burn out, and only high-end can be used to exert power.
Electric vehicles are driven by electricity, and they are mainly adjusted by the power system and do not need to rely on oil separation.
Electric vehicles generally use low gear when driving on the road or downhill and switch to medium and high bags at high speed.
In addition, electric vehicles on slopes with a slope of 30 degrees and below can generally go up. Still, some electric cars beyond this angle cannot support the required power for climbing, so most electric vehicles are best only in the Drive on smooth roads.
The reason why electric tricycles are weak in climbing and starting
Motor problem
First, the primary factor we need to consider is the motor problem.
Why do you say that?
Because the motor has the most direct impact on the power of the electric tricycle.
If it has aged, it will cause the motor to demagnetize.Once the motor is demagnetized, it will be powerless when driving it.
The most direct manifestation is a lack of power, not running fast or far.
In this case, in general, repairing the motor has little effect.
Only by choosing to replace the new motor can the problem of insufficient power of the electric tricycle be solved.
Controller problem
Second, we need to consider the controller problem. Why do you say that?
Although the controller is insignificant, it plays a linking role in the electric tricycle.
If there is poor line contact inside it, it will make the entire line unstable.
The most direct manifestation is that the electric tricycle is intermittent and unable to increase its speed, which is insufficient power.
You can find the part with poor contact for this problem and fix it. If it’s just loose and detached, connect it.
And if one of the cables is corrupted, you can only replace it with a new one.
Battery problem
Also, the last thing we can’t ignore is the battery issue.
Why do you say that?
If the battery has been aged and charged,
Then, if you charge the electric tricycle at this time, although the tricycle seems to be fully charged on the surface,
The charging effect is only less than 50%, and the power of the tricycle is still insufficient. Why do you say that?
In this case, generally speaking, the problem of insufficient power of the electric tricycle can only be solved by replacing the battery with a new one.
Resistance problem
Finally, we also need to see if the resistance problem is causing the lack of power in the electric tricycle.
It is mainly reflected in two aspects, including brakes and tires.
From the perspective of braking, if it fails and increases the driving resistance, it will also cause insufficient power for the electric tricycle.
From the perspective of tires, it mainly checks whether there are foreign objects stuck, which increases the driving resistance.
In general, for these two aspects, repair and removal can be done.
How to make electric vehicles climb more powerfully
The electric vehicle needs to use the slow gear of the vehicle to climb the slope. In this mode, the torque of the vehicle increases, and the climbing force will increase.
The specific operation steps are as follows:
Turn the electric car key door to turn on the power.
Set the speed of the handle to low speed mode.
Find the speed lever of the vehicle.
Pull up to enter the slow sense mode.
Turning the handle down is the state of maximum torque, and it is also powerful when going uphill.
Precautions:
- The speed is plodding in this mode, and it needs to be changed back when the road is flat.
- This mode can also be used when the car is trapped.
