1. A control system for improving battery output energy efficiency, applied to an automotive diagnostic tablet comprising a powered system, the control system comprising a battery, a charging chip, a voltage conversion module, and a power supply management module, wherein:
the battery is connected to the charging chip, the charging chip is connected to the voltage conversion module, and the voltage conversion module is connected to the power supply management module;
the battery is configured to send, when the control system is not connected to an external power supply, battery voltage to the voltage conversion module by means of the charging chip;
the voltage conversion module is configured 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 the output voltage to the power supply management module; and
the power supply management module is configured to output at least one system voltage on the basis of the output voltage, the at least one system voltage being used to supply power to the powered system.
