As a new type of chemical energy storage device for power grids, super capacitors play an important role in life. They are used in different places with high power and large capacity. They can also be green and environmentally friendly and require no maintenance.
People will be confused by the super capacitor's name. To be easier for understanding, you can take it as a special energy storage device similar to a battery. It is based on the electrochemical element between the ordinary battery and the capacitor, and the energy is stored by polarizing the electricity, which is not only highly reversible but also a physical change process.
1. Transportation
Super capacitors can play their role in transportation, mainly in electric and hybrid vehicles. The two have relatively high requirements for power energy, and the battery is affected by various reasons, and the output and life are limited. At this time, the product can play a greater role and achieve better results.
2. Electronics
The characteristics of super capacitors are that they can be charged in a shorter time and provide high currents instantaneously. When the system voltage suddenly drops, it can be used as a backup power supply. In some consumer electronics, it can play a better role to extend its service life and achieve a better working state.
1. Influence on capacitor life
The life of the capacitor will decrease as the temperature increases. Under normal circumstances, whenever the temperature increases by 10 degrees Celsius, the life of the super capacitor will be reduced by half. Any capacitor has an operating temperature range. For example, taking a capacitor with qualified quality as an example, the proper working temperature is about 20 to 120 degrees, and it can work for more than 30,000 hours between 20 and 40 degrees, but if the working temperature is at the extreme temperature, the working life will be shortened to less than 3000 hours. Therefore, when choosing to buy capacitors, high-quality high-temperature-resistant capacitors are better choices.
2. Influence on super capacitor capacity
The capacitance of the capacitor also changes with temperature, which is called the temperature coefficient of the capacitor. When the temperature is too high, the compensation ability of the supercapacitor will be reduced, and it will also produce harmonic resonance with a certain frequency in the power grid, causing certain damage to the system. Therefore, we should consider the effect of temperature on the work of the super capacitor. Otherwise, the capacity of the super capacitor will be reduced, resulting in damage to the system.
3. Influence on capacitor loss
Surely, the increase in temperature will also have a certain influence on the loss of the super capacitor. Generally speaking, as the temperature increases, the tangent value of the super capacitor will be higher. If it works at 140 degrees, the tangent value may be relatively low, which indicates that the temperature is very damaging to the super capacitor.
