What is the difference between a battery and a capacitor in use, whether the capacity between them is different, and what is the difference between a capacitor and a battery in terms of charging efficiency, and who will be stronger in discharging? Next, let me show you how to understand Bar.

First of all, let's talk about the difference in capacity

The capacity of the battery is generally much higher than that of the capacitor, but the charging and discharging speed of the capacitor is not comparable to that of the battery. Batteries store more electricity, but capacitors store less electricity

The second is the difference in charging speed

Generally speaking, the battery charges slowly and the capacitor charges quickly. Batteries are rarely charged with high current, but most capacitors can be charged with high current.文章配图17

Capacitors charge quickly and discharge quickly, which can instantly provide large current to high-power electrical appliances. The capacity of the battery is large, but the discharge is slow, and it can supply power to the appliance for a long time.

Generally speaking, the battery capacity is large, and the charging is slow and the discharging is slow. It cannot be charged instantly with high current, nor can it be discharged with high current instantaneously. The battery is generally used as a power supply in the circuit, and the capacity of the capacitor is small.

The third difference in efficiency

The conversion efficiency of the energy form of the battery is lower than that of the capacitor, the battery is easy to heat, and the usage conditions will be greatly restricted.

The difference in the fourth usage scenario

The battery is mainly used for energy storage, and the capacitor can filter LC filter, energy storage, bypass capacitor, coupling, phase shift, and rectifier circuit smoothing.
