What are the benefits of using supercapacitors in parallel with lithium batteries?
As an energy storage device on a par with batteries, supercapacitors have the most notable features of high power density, large capacitance, fast charging, high-current discharge, high charge and discharge times (500,000 times), safety, and environmental protection. The disadvantages are large volume, low energy density, high self-discharge rate, and low monomer withstand voltage. And compared with the battery, like other capacitors, its voltage continues to drop during the discharge process.
Based on the above characteristics, supercapacitors are not suitable as the main energy storage unit, but are widely used in energy recovery systems to improve startup performance. There are two ways to charge the super capacitor: fixed resistance and fixed current. The fixed resistance method is relatively simple, but the loss of power on the resistance is relatively large, and the charging is slow, generally used in pre-charge. Fixed current charging is similar to charging lithium batteries, but the charging current can be much larger. According to the characteristics of supercapacitors, one of its main applications is to be connected in parallel with power batteries to provide large currents when the load suddenly increases.
As a lithium battery, the instantaneous current that can be provided is much smaller than that of lead batteries, so it should be a good choice to use super capacitors in electric vehicles or hybrid vehicles powered by lithium batteries.
The use of supercapacitors to effectively provide high-power pulse output is the main responsibility, and the life of the power battery is naturally longer, and it is easier to successfully complete the purpose of use with a battery with a slightly lower output power.
