摘要： A control system (100) and a method for improving battery output energy efficiency, and an electronic device. The system (100) comprises: a battery (10), a charging chip (20), a voltage conversion module (30), and a power supply management module (40). The battery (10) is used to send, when the control system (100) is not connected to an external power supply, battery voltage to the voltage conversion module (30) by means of the charging chip (20). The voltage conversion module (30) is used to receive the battery voltage, determine an operating mode on the basis of the battery voltage, acquire an output voltage corresponding to the operating mode, and output said output voltage to the power supply management module (40). The power supply management module (40) is used to convert and output at least one system voltage on the basis of the output voltage, said at least one system voltage being used to supply power to a powered system. The present system (100) is not impacted by high-temperature, low-temperature, or other environments, makes full use of the battery capacity of the power supply module, and lowers the cutoff voltage of the battery (10), thus solving the problems of automotive diagnosis for large power output and short long-duration driving, improving the use experience of a user.
