As one of the most important means of transportation in the mainland, electric vehicles are widely used, and can be used in all aspects of carrying people, goods and goods. Nowadays, people pay more and more attention to the performance and endurance of the vehicle, and the performance of the vehicle is strong, durable, and less problematic; the endurance is expressed in power saving and more running. In order to save electricity, major car companies have launched a variety of power-saving models, especially now there is a saying that electric vehicles can be charged while walking, is this function true? It can be said that there is 90% of the moisture, there are also publicity gimmicks, in the end is there an electric car can be charged while walking? Today, Duo Bin took you to talk about this problem.
What are the models in the market where electric vehicles can save?
Want electric vehicles to run more roads, many car owners have adopted a variety of power-saving modes, what are the power-saving modes often used? There are 3 aspects.
Method one: use the right method for riding,
The speed of electric vehicles from 25 to 55 kilometers per hour, electric vehicles run the slowest and fastest, are more power-consuming, electric vehicles in the driving of the most power-saving mode is 2 gears, average speed, speed control at about 35 km / h.
The battery configuration of the same model is fully charged with two gears at one time, which can increase the endurance by about 15 kilometers than the first or third gear, which can make the car save power and increase the endurance.
Like riding an electric bicycle, the earliest name is an electric assisted bicycle, when starting, you need to pedal a few times like a bicycle, the electric vehicle can start quickly, and you can use the foot pedal mode when the uphill is almost out of power, so that the endurance can run 10 kilometers more.
This principle is equipped with a controller and instrument energy recovery function system, through the motor to receive the remaining energy into the battery.
There are two parts of energy recovery, the first is that when the motor of the electric vehicle is running, the power of the battery is output to the motor, and the motor converts the electrical energy into the drive system of the kinetic energy output to the car, and drives smoothly through the wheels.
How is excess motor energy generated? How do you store your battery? In general, electric vehicles use rear-wheel motors to generate energy recovery when they go downhill or brake, and then recover energy into the battery through the controller to increase the range of electric vehicles.
Take the Yadi Guanneng 2.0 series, which is equipped with a TTFAR energy recovery controller, which can convert the kinetic energy generated by the electric vehicle when it goes downhill, taxiing and braking, and convert it into electrical energy through the energy recovery system, so as to "charge while riding".
With the electric vehicle's power recovery is a truth, you can see the information of energy recovery on the TTFAR power monitoring instrument. When you show green, it means that you are in the process of energy recovery, which shows the amount of electricity you have recovered from this ride.
Method 3: By range increase system and drag reduction method
Some models are also equipped with low roll-off tires, the body has also been optimized for drag reduction, and some cars are also equipped with a range extension system. These many additional functions are all to reduce energy consumption and be able to recover some electrical energy to increase endurance.
Yadi Guanneng series models, the core components of the TTFAR 7-level range increase system are composed of 7 core components, including TTFAR motors, TTFAR graphene batteries, TTFAR energy recovery controllers, three complementary core components, as well as TTFAR power monitoring instruments, TTFAR low rolling resistance tires, TTFAR resistance drop cables and TTFAR low wind resistance body four major hardware components. Through a full range of technical optimization, the mileage can be comprehensively improved.
The above three methods are also used by electric vehicle movable property, and the latter two are increased on electric vehicles, and the sales price will be more expensive. Don't slip away, the important content is in the back, understand how to do electric vehicles to save electricity and have a long endurance.
Can ordinary people do it while walking and charging? Experiment to get the answer
Electric vehicles without energy recovery systems and functions can be said to be basically impossible in terms of energy recovery, and only by operating the correct power saving mode in charging and vehicle use can the battery life be increased.
Can ordinary electric vehicles be charged while walking? Through a small experiment to get the answer, the controller phase line is connected to the bulb, see if the motor rotation can make the bulb power generation light up.
First remove the back seat treasure of the electric vehicle, find the three thick phase lines of the controller yellow, green and blue, in any two lines, connect a 12-volt light bulb on the Yellow Island Green Line, in order to make the oath to do the real, the battery of the electric vehicle is all disconnected, the body of the electric vehicle, the controller is completely without electricity.
First of all, turn the motor in the positive direction of the hand, see the LED bulb lit up a little, soon extinguished, and then turned positively, the bulb is also lit, do this small test electric vehicle motor can indeed generate electricity.
Can the motor generate electricity and recharge the battery? Use a multimeter to measure the current of the motor phase line, and the red and black meter wall is inserted into any two wire lines to see whether the electricity emitted by the motor is AC or DC.
First hit the multimeter on the DC 200 gear, or in the rotation of the motor to see the change of the situation reversed, there is no response on the multimeter, and the positive rotation is also unresponsive.
Secondly, the multimeter is hit on the AC 200V gear, and through the forward and reverse, there is a slight flashing change on the multimeter, indicating that the motor is emitting alternating current.
Electric vehicle battery uses DC, the motor emits ac power is not able to enter the battery, the same with AC voltage to measure the output voltage of the battery, see the table shows only 0.1V, and then with the DC file measurement, the battery voltage is 11.6V is a very normal voltage.
So, the battery output is direct current, the motor produces alternating current, how does the battery voltage power the motor? It is that the vehicle is equipped with a controller, and its role is to replace the motor of the DC battery with an alternating current power supply machine for use and drive.
This controller can only convert the direct current into alternating current, and cannot convert the alternating current sent by the motor into direct current, so it cannot be converted, nor can it be done to charge the battery while the electric vehicle is walking.
So, what do you think about charging electric vehicles while walking? Welcome to leave a message to communicate.
