Abstract
This invention discloses a battery cluster comprising multiple battery packs configured to be electrically coupled to each other and electrically coupled to an external electrical device. Each battery pack includes a charging / discharging circuit, a low-voltage interface, and a high-voltage interface. The multiple battery packs include at least one first-type battery pack and at least one second-type battery pack. The first-type battery pack has a pack-level battery management circuit and a high-voltage switching circuit located in the high-voltage power path. The second-type battery pack does not have a pack-level battery management circuit but includes a battery monitoring circuit. The first-type and second-type battery packs are interconnected such that the same high-voltage power path extends through both, and activating the high-voltage switching circuit of the first-type battery pack interrupts the current flowing through the high-voltage power path. The pack-level battery management circuit communicates with the battery monitoring circuit through the low-voltage interface to obtain measurement information and control at least the high-voltage switching circuit.
