HIERARCHICAL THREE-LEVEL CONTROL SYSTEM OF HIGH-VOLTAGE BATTERY OF ELECTRICAL ENERGY STORAGE UNITS

摘要

FIELD: electricity.;SUBSTANCE: hierarchical three-level control system of a high-voltage battery of electrical energy storage units refers to electrical engineering and can be used at creation of high-voltage batteries for needs of transport and electric-power industry. Essence of the invention consists in the fact that to a system containing microcontroller control units of storage units, modules of storage units and the whole battery, which are fed from a battery and connected to each other via series channels of communication to galvanic isolation, there introduced is a back-up communication channel of emergency warning based on in-series connected electronic switches and galvanic isolation devices, which is connected at the control level of the battery to an output of a one-time command of the microcontroller of the battery control unit, and at control levels of modules and storage units - to an input of interruption of the microcontroller of the corresponding control units of modules and storage units.;EFFECT: provision of a possibility of emergency warning of microcontrollers of control units of storage devices and modules of a system and their transfer to a standby state by bypassing series communication channels.;1 dwg
