Abstract

A connecting method of combining battery units with relatively low power and relatively low voltage into a battery system. The battery units with relatively low power are connected first in series and then in parallel so as to form a battery combination. Meanwhile, every two batteries connected in series are considered as a minimum combination unit and a central signal of each minimum combination unit is led to a battery management system. Both terminals of the minimum combination unit, except for the positive and negative poles of the battery combination, are connected to the corresponding reference signals in the same row through their respective fuses. The fuses have the function of protecting from severe faults of the corresponding battery.
