The application of supercapacitors in medical devices can be combined with batteries to discharge large currents. The large pulse energy provided by the capacitor can meet the requirement of adding all currents to the corresponding system in high-power systems.
For example, medical X-ray machines have a high instantaneous power during exposure and photography. For mobile X-ray machines, there is usually a backup battery. When using the battery, if the X-ray machine is frequently used for exposure, the battery life will be shortened due to the impact of instantaneous high current discharge. Even if the battery cannot provide the required current pulse, the photography may not be clear. For commercial X-ray machines, the impact of instantaneous high current on the power grid when starting photography is also significant, which can easily lead to poor power quality and other problems in the power grid. The instantaneous high-power characteristic of using supercapacitors can meet the current required for X-ray machine photography, thereby solving the above problems.
