Abstract
A battery assisting apparatus and a related device. The battery assisting apparatus includes a piezoelectric transformer group which includes N piezoelectric transformers and a drive circuit group which includes N drive circuits. Respective output ends of the N drive circuits are connected to respective input ends of the N piezoelectric transformers in a one-to-one correspondence, and respective output ends of the N piezoelectric transformers are connected to N battery cells in a battery string. M drive circuits in the N drive circuits are configured to respectively output first pulse signals to M piezoelectric transformers in the N piezoelectric transformers. Each of the M piezoelectric transformers is configured to receive the first pulse signal, and output, driven by the first pulse signal, electric energy to a battery cell corresponding to each piezoelectric transformer for charging, so that voltages of the N battery cells are consistent.
