The advent of supercapacitors has made people curious about its "super" features, what exactly makes it super, and in what fields can its "super" be demonstrated.

Supercapacitors play a significant role in many application fields. Whether as an active power source or a backup power source, they have become an indispensable part of the energy storage industry. Here are some examples of supercapacitor applications in the automotive field:

Some friends in the automotive field have started to pay attention to supercapacitors after learning about their "super" features. They want to know whether supercapacitors can be used in the automotive field. The answer is yes. Some friends also asked : Can supercapacitors accelerate cars? Let's see whether supercapacitors can play their super role in the automotive field.

Let’s first look at what role supercapacitors can play from the perspectives of fuel vehicles and new energy vehicles?

1. Application of supercapacitors in fuel vehicles

1. Improvement of electrical performance: stabilizes the voltage in the automotive circuit;

2. Improved starting performance: Starting the car at low temperatures is no longer a problem;

3. Improvement of battery status: greatly increases the service life of the battery.

2. Application of supercapacitors in new energy vehicles

1. In the field of new energy vehicles, supercapacitors can be used in conjunction with secondary batteries to form a power source for electric vehicles with stable performance, energy saving and environmental protection.

2. Secondary batteries solve the problem of charging and storing energy for cars and providing lasting power for cars, while the mission of supercapacitors is to provide high-power auxiliary power when starting and accelerating the car.

3. Collect and store energy when the car is braking or idling, decelerating, going downhill, or braking. The excess irregular power generated by the car during operation is safely converted into charging energy for the battery to protect the safe and stable operation of the battery; when starting or accelerating, the battery first transfers energy to the supercapacitor, which can provide the required peak energy in a short time.

Through the above understanding of supercapacitors in the automotive field, everyone must also know the answer to the question of whether supercapacitors can accelerate cars. Supercapacitors can not only accelerate cars, but also play many "super" roles. I believe that in the future, the road of supercapacitors will go further and further as cars travel farther.

1. Batteries with a capacity of tens or hundreds of ampere hours cannot stabilize the voltage of the car circuit? Why do we have to rely on supercapacitors with a capacity hundreds or thousands of times smaller to stabilize the voltage?

2. If the battery is broken, the supercapacitor is useless and it can't start the car...

3. The life of the battery is related to many factors such as the usage method and the environment. No matter how powerful the supercapacitor is, it cannot change the fate of the lead-acid battery (over-discharge, long-term storage, circuit leakage, etc.).

Those "magic tools" on Taobao that claim to save fuel by plugging something into the cigarette lighter are obviously "magic tools for harvesting IQ taxes"...

When the car starts, the current is much higher than the current during normal operation, so supercapacitors are still useful.

The high starting current is a characteristic of gasoline engines, and it is not a problem for pure electric vehicles.
