What are the improvements of supercapacitors in the use of cars?
1. Improvement of electrical function. The voltage drop at the moment of starting, the starting current, the output power of the power supply at the starting moment, the stable voltage during the starting process, the stable current during the starting process, and the average output power of the power supply during the starting process are all improved.
2. The improvement of the starting function. At a temperature of 10°C, the battery without the supercapacitor can be started, but the speed and function of the motor are very good when the supercapacitor is connected in parallel with the battery. Supercapacitors can especially improve the starting performance in cold weather. At -20°C, because the performance of the battery is greatly reduced, it is likely to be difficult to start normally or to start normal combustion after multiple starts. However, when the supercapacitor is connected in parallel with the battery, it only needs to be burned once. The advantages are very obvious.
3. Changes in battery usage status. Because the equivalent series resistance of the supercapacitor is much lower than the internal resistance of the battery, at the moment of starting, the supercapacitor outputs a large current, thereby reducing the output current of the battery, effectively reducing the polarization of the battery plate, and preventing the rise of the internal resistance of the battery. , so that the stable voltage of the starting process is improved. This increases the battery life.
