Provided is an apparatus for battery diagnosis and module state change device capable of receiving power from a battery module through a connector connection with a battery module and operating, changing a diagnosis reference value for diagnosing, by a battery management system (BMS), a battery, and changing a setting value of the BMS to change a use of the battery module.

External diagnostics and module status change devices for battery modules

The present disclosure relates to a method for preventing duplicate allocation of an ID to battery modules, and in particularly, to a method for preventing duplicate allocation of an ID to battery modules wherein an ID is prevented from being allocated in a duplicated manner by diagnosing each state where the ID is to be allocated in a duplicated manner.

Method for preventing duplicate allocation of ID to battery modules

The present invention relates to a method of automatically setting a communication resistance of an energy storage device (ESS), and more particularly, to a method of automatically controlling connection of a battery module and a terminating resistance by using a battery management system (BMS) ID allocated to each battery module constituting the ESS.

Communication terminating resistance automatic setting method of energy storage system

The present invention provides a device and method for waking up an MCU of a BMS operating in a sleep mode. More specifically, the present invention provides a device and method for waking up an MCU of a BMS that is in a sleep mode automatically by generating a wake-up signal only once, when an external power source is connected, without user's operation.

MCU wake-up device and method in sleep mode

A thermoplastic resin composition including 10 to 35 wt % of a first graft copolymer resin in which 55 to 65 parts by weight of a diene-based rubber polymer and 35 to 45 parts by weight of a monomer mixture, in which an aromatic vinyl monomer and a vinyl cyanide monomer are mixed in a weight ratio of 60 to 80:20 to 40 respectively, are graft-polymerized, 10 to 30 wt % of a first copolymer resin in which an aromatic vinyl monomer and a vinyl cyanide monomer are copolymerized in a weight ratio of 60 to 80:20 to 40 respectively, 30 to 75 wt % of a polycarbonate resin, and 2 to 8 wt % of a conductive filler.
