Abstract

The invention provides a power supply system capable of switching different power modes, and the system comprises a first power supply module which is used for outputting a first power supply voltage; the second power supply module is used for outputting a second power supply voltage; a battery management module; the main control module is used for starting according to the first power supply voltage after the system power supply end is powered on, establishing communication with the battery management module and entering a normal power operation mode; and in an abnormal power operation mode, the main control module controls the second power supply module to output the second power supply voltage, and after normal output of the second power supply voltage is detected, the first power supply voltage output by the first power supply module is closed, and the second power supply module is controlled to output a third power supply voltage. According to the invention, two power supplies with different powers and corresponding control circuits are combined to supply power to a BMS digital part circuit.

Description

technical field [0001] The invention belongs to the technical field of power supply design, and relates to a power supply system, in particular to a power supply system for switching between different power modes. Background technique [0002] At present, the main power supply of BMS (Battery Management System, battery management system) is generally provided by a lithium battery pack, which is a wide voltage input range. With the development of the industry, traditional BMS has gradually increased many communication requirements, such as isolated 485 communication, isolated CAN (Controller Area Network, controller area network) communication, 4G communication, etc. These requirements and the characteristics of the total voltage power supply lead to the selection of a wide voltage input, high power output BUCK step-down power management IC (Integrated Circuit, integrated circuit) chip when designing a BMS power supply. When the battery pack is in a normal state of use, the ...
