Modern portable power tools use a battery as a power source and require instantaneous high power and long life, and require fast charging.
Super capacitor and battery hybrid test cutting time less than 5 seconds. Initially only alkaline batteries were used. The cutting time was 10 seconds, which was much longer than 5 seconds. Using a supercapacitor in parallel with the battery can provide a 3—5S cutting time, using a supercapacitor to carry high currents, and cutting times of 100 times. This is a noticeable change and the battery life will be doubled due to the reduction of peak current. The results show that the addition of a supercapacitor allows the product to meet the performance requirements of the application.
