Working principle of ER18505+RHC1520 / upc1520 /hpc1520 composite power supply

(1) The battery is assembled in parallel with the RHC/UPC/EPC/HPC/SLC composite capacitor. The battery is a LiSOCL2 battery energy type with higher safety;

(2) The high pulse discharge is completed by the RHC/UPC/EPC/HPC/SLC composite capacitor, and the capacitor has no voltage hysteresis and no passivation effect;

(3) All high-pulse discharges are completed by the RHC/UPC/EPC/HPC /SLCcomposite capacitor. Before the next pulse comes, the capacitor is fully charged again. After the capacitor is fully charged, the discharge capacity remains unchanged until the battery capacity is exhausted, which can ensure the discharge capacity of the battery pack;
