▎ 摘　　要

NOVELTY - The device (102) has a first wired interface (303.1) for accessing a multiplexed wired network and a processor (302) for generating an alert signal upon detection of failure of a battery. A second wired interface (303.2) is directly connected to an entity external to the battery. The processor transmits an alert signal to the external entity through the second wired interface upon detection of the failure of the battery. The second wired interface is directly connected to the external entity connected to the battery. The processor transmits an alert signal to the external entity through the first or second direct wired interfaces. USE - Battery management device for managing and monitoring a traction battery e.g. lithium-ion battery, lithium-metal polymer and graphene battery, of a vehicle e.g. motor vehicle such as moped, storage robot in a warehouse, and electric vehicle. ADVANTAGE - The device allows a man-machine interface connected to a centralized management device of a vehicle such that the centralized management device of the vehicle can control the man-machine interface so as to generate an audible or visual alert, thus improving safety for the driver in an event of failure of the battery upon receipt of the alert signal. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: (1) a method for transmitting an alert signal implemented by a battery management device; (2) a battery management system; and (3) a computer program comprising a set of instructions for transmitting an alert signal implemented by a battery management device. DESCRIPTION OF DRAWING(S) - The drawing shows a block diagram of a battery management device.
