Title:
BIDIRECTIONAL CHARGING MANAGEMENT SYSTEM AND BATTERY SUPERVISION DEVICE THEREOF
Document Type and Number:
WIPO Patent Application WO/2023/125826
Kind Code:
A1
Abstract:
Disclosed are a bidirectional charging management system and a battery supervision device thereof. The battery supervision device comprises at least one battery pack management unit, and each battery pack corresponds to one battery pack management unit; the battery pack management unit comprises a common-mode rejection circuit, a first power supply module and a first control module, and the common-mode rejection circuit is electrically connected to an external alternating-current power supply; the common-mode rejection circuit comprises several EMI power line filters, and the first power supply module is used for supplying power to the first control module; and the common-mode rejection circuit is used for blocking a common-mode current formed in a corresponding circuit during the process of the first power supply module supplying power to the first control module. According to the present invention, a common-mode rejection circuit is additionally arranged in the battery supervision device. For example, an isolation transformer, EMI power line filters and the like are added at an inlet of an alternating-current power supply, so that a common-mode current formed in a corresponding circuit is promptly blocked during the process of a first power supply module supplying power to a first control module, thereby achieving a good common-mode rejection effect.
